Safety BeltsThis section of the manualdescribes how to use safety beltsproperly. It also describes somethings not to do with safety belts.

{ WARNING

Do not let anyone ride wherea safety belt cannot be wornproperly. In a crash, if you or yourpassenger(s) are not wearingsafety belts, injuries can be muchworse than if you are wearingsafety belts. You can be seriouslyinjured or killed by hitting thingsinside the vehicle harder or bybeing ejected from the vehicle.In addition, anyone who is notbuckled up can strike otherpassengers in the vehicle.

(Continued)

WARNING (Continued)

It is extremely dangerous toride in a cargo area, inside oroutside of a vehicle. In a collision,passengers riding in these areasare more likely to be seriouslyinjured or killed. Do not allowpassengers to ride in any area ofthe vehicle that is not equippedwith seats and safety belts.

Always wear a safety belt, andcheck that all passenger(s) arerestrained properly too.

This vehicle has indicators as areminder to buckle the safety belts.See Safety Belt Reminders onpage 5‑11 for additional information.

Why Safety Belts Work

When riding in a vehicle, you travelas fast as the vehicle does. If thevehicle stops suddenly, you keepgoing until something stops you.It could be the windshield, theinstrument panel, or the safety belts!

Seats and Restraints 3-13

When you wear a safety belt, youand the vehicle slow down together.There is more time to stop becauseyou stop over a longer distance and,when worn properly, your strongestbones take the forces from thesafety belts. That is why wearingsafety belts makes such goodsense.

Questions and Answers AboutSafety Belts

Q: Will I be trapped in the vehicleafter a crash if I am wearing asafety belt?

A: You could be — whether youare wearing a safety belt or not.Your chance of being consciousduring and after a crash, so youcan unbuckle and get out, ismuch greater if you are belted.

Q: If my vehicle has airbags, whyshould I have to wear safetybelts?

A: Airbags are supplementalsystems only; so they work withsafety belts — not instead ofthem. Whether or not an airbagis provided, all occupants stillhave to buckle up to get themost protection.

Also, in nearly all states and inall Canadian provinces, the lawrequires wearing safety belts.

How to Wear Safety BeltsProperlyThis section is only for people ofadult size.

There are special things to knowabout safety belts and children.And there are different rules forsmaller children and infants. If achild will be riding in the vehicle,see Older Children on page 3‑36or Infants and Young Children onpage 3‑38. Follow those rules foreveryone's protection.

Safety Belt Use DuringPregnancySafety belts work for everyone,including pregnant women. Like alloccupants, they are more likely tobe seriously injured if they do notwear safety belts.

A pregnant woman should weara lap-shoulder belt, and the lapportion should be worn as lowas possible, below the rounding,throughout the pregnancy.

The best way to protect the fetus isto protect the mother. When a safetybelt is worn properly, it is more likelythat the fetus will not be hurt in acrash. For pregnant women, as foranyone, the key to making safetybelts effective is wearing themproperly.

Safety Belt ExtenderIf the vehicle's safety belt will fastenaround you, you should use it.

But if a safety belt is not longenough, your dealer will order youan extender. When you go in toorder it, take the heaviest coat youwill wear, so the extender will belong enough for you. To help avoidpersonal injury, do not let someoneelse use it, and use it only for theseat it is made to fit. The extenderhas been designed for adults.Never use it for securing child seats.To wear it, attach it to the regularsafety belt. For more information,see the instruction sheet that comeswith the extender.

Safety System CheckNow and then, check that the safetybelt reminder light, safety belts,buckles, latch plates, retractors,and anchorages are all workingproperly. Look for any other loose ordamaged safety belt system partsthat might keep a safety belt systemfrom doing its job. See your dealerto have it repaired. Torn or frayedsafety belts may not protect you ina crash. They can rip apart underimpact forces. If a belt is torn orfrayed, get a new one right away.

Make sure the safety belt reminderlight is working. See Safety BeltReminders on page 5‑11 for moreinformation.

Keep safety belts clean and dry.See Safety Belt Care on page 3‑20.

airbag for the right frontpassenger.

. A roof-rail airbag for the driverand the passenger seateddirectly behind the driver.

. A roof-rail airbag for the rightfront passenger and thepassenger seated directlybehind the right front passenger.

All of the airbags in the vehicle willhave the word AIRBAG embossedin the trim or on an attached labelnear the deployment opening.

For frontal airbags, the wordAIRBAG will appear on the middlepart of the steering wheel for thedriver and on the instrument panelfor the right front passenger.

With seat-mounted side impactairbags, the word AIRBAG willappear on the side of the seatbackclosest to the door.

With roof-rail airbags, the wordAIRBAG will appear along the trim.

Airbags are designed to supplementthe protection provided by safetybelts. Even though today's airbagsare also designed to help reducethe risk of injury from the force of aninflating bag, all airbags must inflatevery quickly to do their job.

Here are the most important thingsto know about the airbag system:

{ WARNING

You can be severely injuredor killed in a crash if you arenot wearing your safety belt,even with airbags. Airbags aredesigned to work with safetybelts, not replace them. Also,airbags are not designed to inflatein every crash. In some crashessafety belts are the only restraint.See When Should an AirbagInflate? on page 3‑24.

Wearing your safety belt duringa crash helps reduce the chanceof hitting things inside the vehicleor being ejected from it. Airbagsare “supplemental restraints” tothe safety belts. Everyone in thevehicle should wear a safety beltproperly, whether or not there isan airbag for that person.

{ WARNING

Because airbags inflate with greatforce and faster than the blinkof an eye, anyone who is upagainst, or very close to anyairbag when it inflates can beseriously injured or killed. Do notsit unnecessarily close to anyairbag, as you would be if sittingon the edge of the seat or leaningforward. Safety belts help keepyou in position before and duringa crash. Always wear a safetybelt, even with airbags. The drivershould sit as far back as possiblewhile still maintaining control ofthe vehicle.

Occupants should not lean onor sleep against the door or sidewindows in seating positions withseat-mounted side impact airbagsand/or roof-rail airbags.

{ WARNING

Children who are up against,or very close to, any airbagwhen it inflates can be seriouslyinjured or killed. Airbags pluslap-shoulder belts offer protectionfor adults and older children,but not for young children andinfants. Neither the vehicle'ssafety belt system nor its airbagsystem is designed for them.Young children and infantsneed the protection that a childrestraint system can provide.Always secure children properlyin the vehicle. To read how, seeOlder Children on page 3‑36 orInfants and Young Children onpage 3‑38.

There is an airbag readiness lighton the instrument panel cluster,which shows the airbag symbol.

The system checks the airbagelectrical system for malfunctions.The light tells you if there is anelectrical problem. See AirbagReadiness Light on page 5‑11for more information.

The roof-rail airbags for the driver,right front passenger, and secondrow outboard passengers are in theceiling above the side windows.

{ WARNING

If something is between anoccupant and an airbag, theairbag might not inflate properlyor it might force the object intothat person causing severe injuryor even death. The path of aninflating airbag must be keptclear. Do not put anythingbetween an occupant and anairbag, and do not attach or putanything on the steering wheelhub or on or near any otherairbag covering.

Do not use seat accessoriesthat block the inflation path of aseat-mounted side impact airbag.

Never secure anything to the roofof a vehicle with roof-rail airbagsby routing a rope or tie‐downthrough any door or windowopening. If you do, the pathof an inflating roof-rail airbagwill be blocked.

When Should an AirbagInflate?Frontal airbags are designedto inflate in moderate to severefrontal or near-frontal crashes tohelp reduce the potential for severeinjuries mainly to the driver's or rightfront passenger's head and chest.However, they are only designedto inflate if the impact exceedsa predetermined deploymentthreshold. Deployment thresholdsare used to predict how severe acrash is likely to be in time for theairbags to inflate and help restrainthe occupants.

Whether the frontal airbags willor should deploy is not based onhow fast your vehicle is traveling.It depends largely on what you hit,the direction of the impact, and howquickly your vehicle slows down.

Seats and Restraints 3-25

Frontal airbags may inflateat different crash speeds.For example:. If the vehicle hits a stationary

object, the airbags could inflateat a different crash speed than ifthe vehicle hits a moving object.

. If the vehicle hits an objectthat deforms, the airbags couldinflate at a different crash speedthan if the vehicle hits an objectthat does not deform.

. If the vehicle hits a narrow object(like a pole), the airbags couldinflate at a different crash speedthan if the vehicle hits a wideobject (like a wall).

. If the vehicle goes into an objectat an angle, the airbags couldinflate at a different crash speedthan if the vehicle goes straightinto the object.

Thresholds can also vary withspecific vehicle design.

Frontal airbags are not intended toinflate during vehicle rollovers, rearimpacts, or in many side impacts.

In addition, the vehicle hasdual-stage frontal airbags.Dual-stage airbags adjust therestraint according to crash severity.The vehicle has electronic frontalsensors, which help the sensingsystem distinguish between amoderate frontal impact anda more severe frontal impact.For moderate frontal impacts,dual-stage airbags inflate at alevel less than full deployment.For more severe frontal impacts,full deployment occurs.

The vehicle has seat-mountedside impact and roof-rail airbags.See Airbag System on page 3‑21.Seat-mounted side impact androof-rail airbags are intended toinflate in moderate to severe sidecrashes. In addition, these roof-railairbags are intended to inflateduring a rollover or in a severefrontal impact. Seat-mounted sideimpact and roof-rail airbags will

inflate if the crash severity is abovethe system's designed thresholdlevel. The threshold level can varywith specific vehicle design.

Seat-mounted side impact airbagsare not intended to inflate in frontalimpacts, near-frontal impacts,rollovers, or rear impacts. Roof-railairbags are not intended to inflate inrear impacts. A seat-mounted sideimpact airbag is intended to deployon the side of the vehicle that isstruck. Both roof-rail airbags willdeploy when either side of thevehicle is struck, or if the sensingsystem predicts that the vehicle isabout to roll over, or in a severefrontal impact.

In any particular crash, no onecan say whether an airbag shouldhave inflated simply because of thedamage to a vehicle or becauseof what the repair costs were.For frontal airbags, inflation isdetermined by what the vehicle hits,the angle of the impact, and howquickly the vehicle slows down.

3-26 Seats and Restraints

For seat-mounted side impact androof-rail airbags, deployment isdetermined by the location andseverity of the side impact. In arollover event, roof-rail airbagdeployment is determined by thedirection of the roll.

What Makes an AirbagInflate?In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from theinflator. Gas from the inflator fills theairbag causing the bag to break outof the cover. The inflator, the airbag,and related hardware are all part ofthe airbag module.

For airbag location, see Where Arethe Airbags? on page 3‑23.

How Does an AirbagRestrain?In moderate to severe frontal ornear frontal collisions, even beltedoccupants can contact the steeringwheel or the instrument panel.In moderate to severe sidecollisions, even belted occupantscan contact the inside of thevehicle.

Airbags supplement the protectionprovided by safety belts.Frontal airbags distribute theforce of the impact more evenlyover the occupant's upper body,stopping the occupant moregradually. Seat‐mounted side impactand roof-rail airbags distribute theforce of the impact more evenlyover the occupant's upper body.

Rollover capable roof-rail airbagsare designed to help contain thehead and chest of occupants in theoutboard seating positions in thefirst and second rows. The rollovercapable roof-rail airbags aredesigned to help reduce the riskof full or partial ejection in rolloverevents, although no system canprevent all such ejections.

But airbags would not help inmany types of collisions, primarilybecause the occupant's motionis not toward those airbags.See When Should an AirbagInflate? on page 3‑24 for moreinformation.

Airbags should never be regardedas anything more than a supplementto safety belts.

Seats and Restraints 3-27

What Will You See afteran Airbag Inflates?After the frontal airbags andseat-mounted side impact airbagsinflate, they quickly deflate, soquickly that some people may noteven realize an airbag inflated.Roof-rail airbags may still be at leastpartially inflated for some time afterthey inflate. Some components ofthe airbag module may be hot forseveral minutes. For location ofthe airbags, see Where Are theAirbags? on page 3‑23.

The parts of the airbag that comeinto contact with you may be warm,but not too hot to touch. There maybe some smoke and dust comingfrom the vents in the deflatedairbags. Airbag inflation does notprevent the driver from seeing outof the windshield or being able tosteer the vehicle, nor does it preventpeople from leaving the vehicle.

{ WARNING

When an airbag inflates,there may be dust in the air.This dust could cause breathingproblems for people with a historyof asthma or other breathingtrouble. To avoid this, everyonein the vehicle should get out assoon as it is safe to do so. If youhave breathing problems butcannot get out of the vehicle afteran airbag inflates, then get freshair by opening a window or adoor. If you experience breathingproblems following an airbagdeployment, you should seekmedical attention.

The vehicle has a feature that mayautomatically unlock the doors,turn the interior lamps on, turn thehazard warning flashers on, and

shut off the fuel system after theairbags inflate. You can lock thedoors, turn the interior lamps off,and turn the hazard warningflashers off by using the controlsfor those features.

{ WARNING

A crash severe enough to inflatethe airbags may have alsodamaged important functionsin the vehicle, such as the fuelsystem, brake and steeringsystems, etc. Even if the vehicleappears to be drivable after amoderate crash, there may beconcealed damage that couldmake it difficult to safely operatethe vehicle.

Use caution if you should attemptto restart the engine after a crashhas occurred.

In many crashes severe enoughto inflate the airbag, windshieldsare broken by vehicle deformation.Additional windshield breakage mayalso occur from the front outboardpassenger airbag.. Airbags are designed to inflate

only once. After an airbaginflates, you will need somenew parts for the airbag system.If you do not get them, theairbag system will not be thereto help protect you in anothercrash. A new system will includeairbag modules and possiblyother parts. The service manualfor the vehicle covers the needto replace other parts.

. The vehicle has a crashsensing and diagnostic modulewhich records informationafter a crash. See VehicleData Recording and Privacy onpage 13‑21 and Event DataRecorders on page 13‑21.

. Let only qualified technicianswork on the airbag systems.Improper service can mean thatan airbag system will not workproperly. See your dealer forservice.

Passenger SensingSystemThe vehicle has a passengersensing system for the right frontpassenger position. The passengerairbag status indicator will be visibleon the overhead console when thevehicle is started.

The passenger sensing systemturns off the right front passengerfrontal airbag under certainconditions. The driver airbag,seat‐mounted side impact airbagsand the roof-rail airbags arenot affected by the passengersensing system.

The passenger sensing systemworks with sensors that are partof the right front passenger seat.The sensors are designed to detectthe presence of a properly-seatedoccupant and determine if the rightfront passenger frontal airbagshould be enabled (may inflate)or not.

According to accident statistics,children are safer when properlysecured in a rear seat in the correctchild restraint for their weightand size.

We recommend that children besecured in a rear seat, including:an infant or a child riding in arear-facing child restraint; a childriding in a forward-facing child seat;an older child riding in a boosterseat; and children, who are largeenough, using safety belts.

A label on the sun visor says,“Never put a rear-facing child seatin the front.” This is because the riskto the rear-facing child is so great,if the airbag deploys.

{ WARNING

A child in a rear-facing childrestraint can be seriouslyinjured or killed if the rightfront passenger airbag inflates.This is because the back of therear-facing child restraint wouldbe very close to the inflatingairbag. A child in a forward-facingchild restraint can be seriouslyinjured or killed if the right front

WARNING (Continued)

passenger airbag inflates and thepassenger seat is in a forwardposition.

Even if the passenger sensingsystem has turned off the rightfront passenger frontal airbag,no system is fail-safe. No onecan guarantee that an airbag willnot deploy under some unusualcircumstance, even though theairbag is turned off.

Secure rear-facing child restraintsin a rear seat, even if theairbag is off. If you secure aforward-facing child restraint inthe right front seat, always movethe front passenger seat as farback as it will go. It is better tosecure the child restraint in arear seat.

3-30 Seats and Restraints

The passenger sensing system isdesigned to turn off the right frontpassenger frontal airbag if:. The right front passenger seat is

unoccupied.. The system determines that

an infant is present in a childrestraint.

. A right front passenger takeshis/her weight off of the seat fora period of time.

. Or, if there is a critical problemwith the airbag system or thepassenger sensing system.

When the passenger sensingsystem has turned off the right frontpassenger frontal airbag, the offindicator will light and stay lit toremind you that the airbag is off.See Passenger Airbag StatusIndicator on page 5‑12.

The passenger sensing system isdesigned to turn on (may inflate)the right front passenger frontalairbag anytime the system sensesthat a person of adult size issitting properly in the right frontpassenger seat.

When the passenger sensingsystem has allowed the airbag to beenabled, the on indicator will lightand stay lit to remind you that theairbag is active.

For some children, includingchildren in child restraints, and forvery small adults, the passengersensing system may or may notturn off the right front passengerfrontal airbag, depending uponthe person’s seating posture andbody build. Everyone in the vehiclewho has outgrown child restraintsshould wear a safety beltproperly — whether or not thereis an airbag for that person.

{ WARNING

If the airbag readiness light evercomes on and stays on, it meansthat something may be wrongwith the airbag system. To helpavoid injury to yourself or others,have the vehicle serviced rightaway. See Airbag ReadinessLight on page 5‑11 for moreinformation, including importantsafety information.

Seats and Restraints 3-31

If the On Indicator is Lit for aChild Restraint

If a child restraint has been installedand the on indicator is lit:

1. Turn the vehicle off.

2. Remove the child restraint fromthe vehicle.

3. Remove any additional itemsfrom the seat such as blankets,cushions, seat covers, seatheaters, or seat massagers.

4. Reinstall the child restraintfollowing the directionsprovided by the child restraintmanufacturer and refer toSecuring Child Restraints(Rear Seat ) on page 3‑51 orSecuring Child Restraints (FrontPassenger Seat) on page 3‑54.

5. If, after reinstalling the childrestraint and restarting thevehicle, the on indicator isstill lit, turn the vehicle off.Then slightly recline the vehicleseatback and adjust the seatcushion, if adjustable, to makesure that the vehicle seatback isnot pushing the child restraintinto the seat cushion.

Also make sure the childrestraint is not trapped underthe vehicle head restraint.If this happens, adjust the headrestraint. See Head Restraintson page 3‑2.

6. Restart the vehicle.

The passenger sensing systemmay or may not turn off theairbag for a child in a childrestraint depending upon thechild’s seating posture and bodybuild. It is better to secure thechild restraint in a rear seat.

If the Off Indicator is Lit for anAdult-Size Occupant

If a person of adult-size is sittingin the right front passenger seat,but the off indicator is lit, it couldbe because that person is notsitting properly in the seat.

3-32 Seats and Restraints

If this happens, use the followingsteps to allow the system to detectthat person and enable the rightfront passenger frontal airbag:

1. Turn the vehicle off.

2. Remove any additional materialfrom the seat, such as blankets,cushions, seat covers, seatheaters, or seat massagers.

3. Place the seatback in the fullyupright position.

4. Have the person sit upright inthe seat, centered on the seatcushion, with legs comfortablyextended.

5. Restart the vehicle and have theperson remain in this position fortwo to three minutes after the onindicator is lit.

Additional Factors AffectingSystem Operation

Safety belts help keep thepassenger in position on theseat during vehicle maneuversand braking, which helps thepassenger sensing system maintainthe passenger airbag status.See “Safety Belts” and “ChildRestraints” in the Index foradditional information about theimportance of proper restraint use.

A thick layer of additional material,such as a blanket or cushion,or aftermarket equipment suchas seat covers, seat heaters, andseat massagers can affect howwell the passenger sensing systemoperates. We recommend thatyou not use seat covers or otheraftermarket equipment except whenapproved by GM for your specificvehicle. See Adding Equipment tothe Airbag-Equipped Vehicle onpage 3‑34 for more informationabout modifications that can affecthow the system operates.

A wet seat can affect theperformance of the passengersensing system. Here is how:. The passenger sensing system

may turn off the passengerairbag when liquid is soakedinto the seat. If this happens,the off indicator will be lit, andthe airbag readiness light on theinstrument panel will also be lit.

. Liquid pooled on the seat thathas not soaked in may make itmore likely that the passengersensing system will enable (turnon) the passenger airbag while achild restraint or child occupantis on the seat. If the passengerairbag is turned on, the onindicator will be lit.

If the passenger seat gets wet, drythe seat immediately. If the airbagreadiness light is lit, do not installa child restraint or allow anyoneto occupy the seat. See AirbagReadiness Light on page 5‑11for important safety information.

Seats and Restraints 3-33

The on indicator may be lit ifan object, such as a briefcase,handbag, grocery bag, laptop orother electronic device, is put onan unoccupied seat. If this is notdesired remove the object fromthe seat.

{ WARNING

Stowing of articles under thepassenger seat or between thepassenger seat cushion andseatback may interfere with theproper operation of the passengersensing system.

Servicing theAirbag-Equipped VehicleAirbags affect how the vehicleshould be serviced. There areparts of the airbag system inseveral places around the vehicle.Your dealer and the service manualhave information about servicingthe vehicle and the airbag system.To purchase a service manual,see Service Publications OrderingInformation on page 13‑18.

{ WARNING

For up to 10 seconds after thevehicle is turned off and thebattery is disconnected, an airbagcan still inflate during improperservice. You can be injured if youare close to an airbag when itinflates. Avoid yellow connectors.They are probably part of theairbag system. Be sure to followproper service procedures, andmake sure the person performingwork for you is qualified to do so.

Adding Equipment to theAirbag-Equipped VehicleQ: Is there anything I might add

to or change about the vehiclethat could keep the airbagsfrom working properly?

A: Yes. If you add things thatchange the vehicle's frame,bumper system, height, frontend or side sheet metal, theymay keep the airbag systemfrom working properly. Changingor moving any parts of the frontseats, safety belts, the airbagsensing and diagnostic module,steering wheel, instrumentpanel, roof-rail airbag modules,ceiling headliner or pillar garnishtrim, overhead console, frontsensors, side impact sensors,rollover sensor module, or airbagwiring can affect the operation ofthe airbag system.

In addition, the vehicle has apassenger sensing systemfor the right front passengerposition, which includessensors that are part of thepassenger seat. The passengersensing system may not operateproperly if the original seattrim is replaced with non-GMcovers, upholstery or trim,or with GM covers, upholsteryor trim designed for a differentvehicle. Any object, such asan aftermarket seat heater ora comfort enhancing pad ordevice, installed under or on topof the seat fabric, could alsointerfere with the operation ofthe passenger sensing system.This could either prevent properdeployment of the passengerairbag(s) or prevent thepassenger sensing systemfrom properly turning offthe passenger airbag(s).See Passenger SensingSystem on page 3‑28.

Seats and Restraints 3-37

The manufacturer's instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat with alap-shoulder belt until the childpasses the fit test below:. Sit all the way back on the seat.

Do the knees bend at the seatedge? If yes, continue. If no,return to the booster seat.

. Buckle the lap-shoulder belt.Does the shoulder belt rest onthe shoulder? If yes, continue.If no, try using the rear safetybelt comfort guide. See “RearSafety Belt Comfort Guides”under Lap-Shoulder Belt onpage 3‑14 for more information.If the shoulder belt still does notrest on the shoulder, then returnto the booster seat.

. Does the lap belt fit low andsnug on the hips, touching thethighs? If yes, continue. If no,return to the booster seat.

. Can proper safety belt fit bemaintained for the length of thetrip? If yes, continue. If no,return to the booster seat.

Q: What is the proper way towear safety belts?

A: An older child should wear alap-shoulder belt and get theadditional restraint a shoulderbelt can provide. The shoulderbelt should not cross the faceor neck. The lap belt should fitsnugly below the hips, justtouching the top of the thighs.This applies belt force to thechild's pelvic bones in a crash.It should never be worn over theabdomen, which could causesevere or even fatal internalinjuries in a crash.

Also see “Rear Safety Belt ComfortGuides” under Lap-Shoulder Belt onpage 3‑14.

According to accident statistics,children and infants are saferwhen properly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition.

In a crash, children who are notbuckled up can strike other peoplewho are buckled up, or can bethrown out of the vehicle. Olderchildren need to use safety beltsproperly.

3-38 Seats and Restraints

{ WARNING

Never do this.

Never allow two children to wearthe same safety belt. The safetybelt cannot properly spread theimpact forces. In a crash, the twochildren can be crushed togetherand seriously injured. A safetybelt must be used by only oneperson at a time.

{ WARNING

Never do this.

Never allow a child to wear thesafety belt with the shoulder beltbehind their back. A child can beseriously injured by not wearingthe lap-shoulder belt properly.In a crash, the child would not berestrained by the shoulder belt.The child could move too farforward increasing the chance ofhead and neck injury. The childmight also slide under the lapbelt. The belt force would thenbe applied right on the abdomen.That could cause serious or fatalinjuries. The shoulder belt shouldgo over the shoulder and acrossthe chest.

Infants and YoungChildrenEveryone in a vehicle needsprotection! This includes infantsand all other children. Neither thedistance traveled nor the age andsize of the traveler changes theneed, for everyone, to use safetyrestraints. In fact, the law in everystate in the United States and inevery Canadian province sayschildren up to some age must berestrained while in a vehicle.

Seats and Restraints 3-39

{ WARNING

Children can be seriously injuredor strangled if a shoulder beltis wrapped around their neckand the safety belt continues totighten. Never leave childrenunattended in a vehicle and neverallow children to play with thesafety belts.

Airbags plus lap‐shoulder beltsoffer protection for adults and olderchildren, but not for young childrenand infants. Neither the vehicle'ssafety belt system nor its airbagsystem is designed for them. Everytime infants and young children ridein vehicles, they should have theprotection provided by appropriatechild restraints.

Children who are not restrainedproperly can strike other people,or can be thrown out of the vehicle.

{ WARNING

Never do this.

Never hold an infant or a childwhile riding in a vehicle. Due tocrash forces, an infant or a childwill become so heavy it is notpossible to hold it during a crash.For example, in a crash at only40 km/h (25 mph), a 5.5 kg (12 lb)infant will suddenly become a110 kg (240 lb) force on a person'sarms. An infant should besecured in an appropriaterestraint.

3-40 Seats and Restraints

{ WARNING

Never do this.

Children who are up against,or very close to, any airbag whenit inflates can be seriously injuredor killed. Never put a rear-facingchild restraint in the right frontseat. Secure a rear-facing childrestraint in a rear seat. It is alsobetter to secure a forward-facingchild restraint in a rear seat. If youmust secure a forward-facingchild restraint in the right frontseat, always move the frontpassenger seat as far backas it will go.

Q: What are the different types ofadd-on child restraints?

A: Add-on child restraints, whichare purchased by the vehicleowner, are available in fourbasic types. Selection of aparticular restraint should takeinto consideration not onlythe child's weight, height, andage but also whether or not therestraint will be compatible withthe motor vehicle in which it willbe used.

For most basic types of childrestraints, there are manydifferent models available.When purchasing a childrestraint, be sure it is designedto be used in a motor vehicle.If it is, the restraint will have alabel saying that it meets federalmotor vehicle safety standards.

The restraint manufacturer'sinstructions that come with therestraint state the weight andheight limitations for a particularchild restraint. In addition, thereare many kinds of restraintsavailable for children withspecial needs.

Seats and Restraints 3-41

{ WARNING

To reduce the risk of neck andhead injury during a crash,infants need complete support.This is because an infant's neckis not fully developed and its headweighs so much compared withthe rest of its body. In a crash,an infant in a rear-facing childrestraint settles into the restraint,so the crash forces can bedistributed across the strongestpart of an infant's body, the backand shoulders. Infants shouldalways be secured in rear-facingchild restraints.

{ WARNING

A young child's hip bones are stillso small that the vehicle's regularsafety belt may not remain lowon the hip bones, as it should.Instead, it may settle up aroundthe child's abdomen. In a crash,the belt would apply force on abody area that is unprotected byany bony structure. This alonecould cause serious or fatalinjuries. To reduce the risk ofserious or fatal injuries during acrash, young children shouldalways be secured in appropriatechild restraints.

Child Restraint Systems

(A) Rear‐Facing Infant Seat

A rear-facing infant seat (A)provides restraint with the seatingsurface against the back of theinfant.

The harness system holds the infantin place and, in a crash, acts tokeep the infant positioned in therestraint.

(B) Forward-Facing Child Seat

A forward-facing child seat (B)provides restraint for the child'sbody with the harness.

(C) Booster Seats

A booster seat (C) is a childrestraint designed to improve the fitof the vehicle's safety belt system.A booster seat can also help a childto see out the window.

Securing an Add-On ChildRestraint in the Vehicle

{ WARNING

A child can be seriously injuredor killed in a crash if the childrestraint is not properly securedin the vehicle. Secure the childrestraint properly in the vehicleusing the vehicle safety belt orLATCH system, following theinstructions that came with thatchild restraint and the instructionsin this manual.

To help reduce the chance of injury,the child restraint must be securedin the vehicle. Child restraintsystems must be secured in vehicleseats by lap belts or the lap beltportion of a lap-shoulder belt, orby the LATCH system.

Children can be endangered in acrash if the child restraint is notproperly secured in the vehicle.

When securing an add-on childrestraint, refer to the instructionsthat come with the restraint whichmay be on the restraint itself or in abooklet, or both, and to this manual.The child restraint instructionsare important, so if they are notavailable, obtain a replacementcopy from the manufacturer.

Keep in mind that an unsecuredchild restraint can move aroundin a collision or sudden stop andinjure people in the vehicle. Be sureto properly secure any child restraintin the vehicle — even when no childis in it.

In some areas, Certified ChildPassenger Safety Technicians(CPSTs) are available to inspectand demonstrate how to correctlyuse and install child restraints.In the U.S., refer to the NationalHighway Traffic SafetyAdministration (NHTSA) websiteto locate the nearest child safetyseat inspection station. For CPSTavailability in Canada, check withTransport Canada or the ProvincialMinistry of Transportation office.

Securing the Child within theChild Restraint

{ WARNING

A child can be seriously injuredor killed in a crash if the childis not properly secured in thechild restraint. Secure the childproperly following the instructionsthat came with that child restraint.

Where to Put theRestraintAccording to accident statistics,children and infants are saferwhen properly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition.

We recommend that children andchild restraints be secured in a rearseat, including: an infant or a childriding in a rear-facing child restraint;a child riding in a forward-facingchild seat; an older child riding in abooster seat; and children, who arelarge enough, using safety belts.

A label on your sun visor says,“Never put a rear-facing child seatin the front.” This is because the riskto the rear-facing child is so great,if the airbag deploys.

3-44 Seats and Restraints

{ WARNING

A child in a rear-facing childrestraint can be seriouslyinjured or killed if the rightfront passenger airbag inflates.This is because the back of therear-facing child restraint wouldbe very close to the inflatingairbag. A child in a forward-facingchild restraint can be seriouslyinjured or killed if the right frontpassenger airbag inflates and thepassenger seat is in a forwardposition.

Even if the passenger sensingsystem has turned off the rightfront passenger frontal airbag,no system is fail-safe. No onecan guarantee that an airbag willnot deploy under some unusualcircumstance, even though it isturned off.

(Continued)

WARNING (Continued)

Secure rear-facing child restraintsin a rear seat, even if theairbag is off. If you secure aforward-facing child restraint inthe right front seat, always movethe front passenger seat as farback as it will go. It is better tosecure the child restraint in arear seat.

See Passenger Sensing Systemon page 3‑28 for additionalinformation.

When securing a child restraint ina rear seating position, study theinstructions that came with thechild restraint to make sure it iscompatible with this vehicle.

Child restraints and booster seatsvary considerably in size, and somemay fit in certain seating positionsbetter than others. Always makesure the child restraint is properlysecured.

Depending on where you placethe child restraint and the size ofthe child restraint, you may notbe able to access adjacent safetybelt assemblies or LATCH anchorsfor additional passengers or childrestraints. Adjacent seatingpositions should not be used if thechild restraint prevents access toor interferes with the routing ofthe safety belt.

Wherever a child restraint isinstalled, be sure to secure thechild restraint properly.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inyour vehicle — even when no childis in it.

3-46 Seats and Restraints

Lower Anchors andTethers for Children(LATCH System)The LATCH system holds a childrestraint during driving or in a crash.This system is designed to makeinstallation of a child restraint easier.The LATCH system uses anchors inthe vehicle and attachments on thechild restraint that are made for usewith the LATCH system.

Make sure that a LATCH-compatiblechild restraint is properly installedusing the anchors, or use thevehicle's safety belts to secure therestraint, following the instructionsthat came with that restraint, andalso the instructions in this manual.

When installing a child restraintwith a top tether, you must alsouse either the lower anchors or thesafety belts to properly secure thechild restraint. A child restraint mustnever be installed using only the toptether and anchor.

In order to use the LATCHsystem in your vehicle, you needa child restraint that has LATCHattachments. The child restraintmanufacturer will provide youwith instructions on how to use thechild restraint and its attachments.The following explains how toattach a child restraint with theseattachments in your vehicle.

Not all vehicle seating positions orchild restraints have lower anchorsand attachments or top tetheranchors and attachments.

Lower Anchors

Lower anchors (A) are metalbars built into the vehicle. Thereare two lower anchors for eachLATCH seating position that willaccommodate a child restraintwith lower attachments (B).

Seats and Restraints 3-47

Top Tether Anchor

A top tether (A, C) anchors thetop of the child restraint to thevehicle. A top tether anchor is builtinto the vehicle. The top tetherattachment (B) on the child restraintconnects to the top tether anchor inthe vehicle in order to reduce theforward movement and rotation ofthe child restraint during driving orin a crash.

Your child restraint may havea single tether (A) or a dualtether (C). Either will have a singleattachment (B) to secure the toptether to the anchor.

Some child restraints that havea top tether are designed foruse with or without the top tetherbeing attached. Others require thetop tether always to be attached.In Canada, the law requires thatforward-facing child restraints havea top tether, and that the tetherbe attached. Be sure to read andfollow the instructions for your childrestraint.

Lower Anchor and Top TetherAnchor Locations

Top Tether Anchors

The top tether anchors for each rearseating position are located on theback of the rear seatback. The rearcompartment storage panel/covermight need to be adjusted to accessthe anchors. Be sure to use ananchor located on the same side ofthe vehicle as the seating positionwhere the child restraint will beplaced.

Do not secure a child restraint in aposition without a top tether anchorif a national or local law requiresthat the top tether be attached, or ifthe instructions that come with thechild restraint say that the top tethermust be attached.

According to accident statistics,children and infants are saferwhen properly restrained in a childrestraint system or infant restraintsystem secured in a rear seatingposition. See Where to Put theRestraint on page 3‑43 foradditional information.

Securing a Child RestraintDesigned for the LATCHSystem

{ WARNING

If a LATCH-type child restraint isnot attached to anchors, the childrestraint will not be able to protectthe child correctly. In a crash, thechild could be seriously injuredor killed. Install a LATCH-typechild restraint properly using theanchors, or use the vehicle safetybelts to secure the restraint,following the instructions thatcame with the child restraint andthe instructions in this manual.

The following may correct anemission system malfunction:. Check that the fuel cap is fully

installed. See Filling the Tank onpage 9‑58. The diagnosticsystem can determine if thefuel cap has been left off orimproperly installed. A loose ormissing fuel cap allows fuel toevaporate into the atmosphere.A few driving trips with the capproperly installed should turnthe light off.

. Check that good quality fuelis used. Poor fuel qualitycauses the engine not to runas efficiently as designed andmay cause stalling after start-up,stalling when the vehicle ischanged into gear, misfiring,hesitation on acceleration,or stumbling on acceleration.These conditions might go awayonce the engine is warmed up.

If one or more of these conditionsoccurs, change the fuel brand used.It will require at least one full tank ofthe proper fuel to turn the light off.

See Recommended Fuel onpage 9‑54.

If none of the above have madethe light turn off, your dealer cancheck the vehicle. The dealerhas the proper test equipmentand diagnostic tools to fix anymechanical or electrical problemsthat might have developed.

When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. If the vehiclehas a voltmeter gauge or a voltagedisplay on the Driver InformationCenter (DIC), you may see thevoltage move up or down. This isnormal. If there is a problem, analert will be displayed.

The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinningfast enough at idle to produce allof the power needed for very highelectrical loads.

A high electrical load occurs whenseveral of the following are on,such as: headlamps, high beams,fog lamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.

EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.

It can increase engine idle speedto generate more power wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Normally, these actions occurin steps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a DIC message mightbe displayed, such as BATTERYSAVER ACTIVE, BATTERYVOLTAGE LOW, or LOW BATTERY.If one of these messages displays,it is recommended that the driverreduce the electrical loads as muchas possible. See Driver InformationCenter (DIC) on page 5‑23.

Radio ReceptionFrequency interference and staticcan occur during normal radioreception if items such as cell phonechargers, vehicle convenienceaccessories, and external electronicdevices are plugged into theaccessory power outlet. If there isinterference or static, unplug theitem from the accessory poweroutlet.

FM

FM signals only reach about 16 to65 km (10 to 40 mi). Although theradio has a built-in electronic circuitthat automatically works to reduceinterference, some static can occur,especially around tall buildings orhills, causing the sound to fade inand out.

AM

The range for most AM stations isgreater than for FM, especially atnight. The longer range can causestation frequencies to interfere witheach other. Static can occur whenthings like storms and power linesinterfere with radio reception. Whenthis happens, try reducing the trebleon the radio.

XM™ Satellite Radio Service

XM Satellite Radio Service givesdigital radio reception from coast tocoast in the 48 contiguous UnitedStates, and in Canada. Just aswith FM, tall buildings or hills caninterfere with satellite radio signals,causing the sound to fade in andout. In addition, traveling or standingunder heavy foliage, bridges,garages, or tunnels may cause lossof the XM signal for a period of time.

Cellular Phone Usage

Cellular phone usage can causeinterference with the vehicle's radio.

Multi-Band AntennaThe multi-band antenna is on theroof of the vehicle. The antennais used for the AM‐FM radio,OnStar, the XM Satellite RadioService System, and GPS (GlobalPositioning System), if the vehiclehas these features. Keep theantenna clear of obstructionsfor clear reception.

9-4 Driving and Operating

Control of a VehicleBraking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.

BrakingBraking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.

Average driver reaction time isabout three‐fourths of a second.In that time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.

Helpful braking tips to keep in mindinclude:. Keep enough distance between

you and the vehicle in frontof you.

. Avoid needless heavy braking.

. Keep pace with traffic.

If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be somepower brake assist but it will beused when the brake is applied.Once the power assist is used up,it can take longer to stop and thebrake pedal will be harder to push.

Steering

Electric Power Steering(2.4L L4 Engine)

If the engine stalls while driving, thepower steering assist system willcontinue to operate until you areable to stop the vehicle.

If power steering assist is lost dueto a system malfunction, the vehiclecan be steered, but may requireincreased effort.

If the steering wheel is turnedin either direction several timesuntil it stops, or it is held until itis stopped for an extended time,power steering assist may bereduced. The normal power steeringassist should return shortly after afew normal steering movements.

Page 219: 2012 GMC Terrain Owner Manual M - Owner Center Home GMC Terrain Owner Manual M Vehicle Care..... 10-1 General ... when you need to see a service manual for additional instructions

Black plate (5,1)GMC Terrain Owner Manual (Include Mex) - 2012

Driving and Operating 9-5

The electric power steeringsystem does not require regularmaintenance. If you suspectsteering system problems, such asabnormally high steering effort fora prolonged period of time, contactyour dealer for service repairs.

Hydraulic Power Steering(3.0L V6 Engine)

If power steering assist is lost dueto a system malfunction, the vehiclecan be steered, but may requireincreased effort.

Curve Tips. Take curves at a reasonable

speed.. Reduce speed before entering a

curve.

. Maintain a reasonable steadyspeed through the curve

. Wait until the vehicle is out ofthe curve before acceleratinggently into the straightaway.

Steering in Emergencies. There are some situations when

steering around a problem maybe more effective than braking.

. Holding both sides of thesteering wheel allows you to turn180 degrees without removinga hand.

. Anti-lock Brake System (ABS)allows steering while braking.

Off-Road Recovery

The vehicle's right wheels candrop off the edge of a roadonto the shoulder while driving.Follow these tips:

1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so thatit straddles the edge of thepavement.

Page 220: 2012 GMC Terrain Owner Manual M - Owner Center Home GMC Terrain Owner Manual M Vehicle Care..... 10-1 General ... when you need to see a service manual for additional instructions

9-6 Driving and Operating

2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.

3. Then turn the steering wheel togo straight down the roadway.

Loss of Control

Skidding

There are three types of skids thatcorrespond to the vehicle's threecontrol systems:. Braking Skid — wheels are not

rolling.. Steering or Cornering

Skid — too much speed orsteering in a curve causes tiresto slip and lose cornering force.

. Acceleration Skid — too muchthrottle causes the drivingwheels to spin.

Defensive drivers avoid most skidsby taking reasonable care suitedto existing conditions, and bynot overdriving those conditions.But skids are always possible.

If the vehicle starts to slide,follow these suggestions:. Ease your foot off the

accelerator pedal and quicklysteer the way you want thevehicle to go. The vehicle maystraighten out. Be ready for asecond skid if it occurs.

. Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues — suchas enough water, ice, or packedsnow on the road to make amirrored surface — and slowdown when you have any doubt.

. Try to avoid sudden steering,acceleration, or braking,including reducing vehiclespeed by shifting to a lowergear. Any sudden changescould cause the tires to slide.

Remember: Antilock brakes helpavoid only the braking skid.

Off-Road DrivingAll-wheel-drive vehicles can beused for off-road driving. Vehicleswithout all-wheel drive and vehiclesnot equipped with All Terrain (AT) orOn-Off Road (OOR) tires must notbe driven off-road except on a level,solid surface. To contact the tiremanufacturer for more informationabout the original equipment tires,see the Limited Warranty andOwner Assistance Informationmanual.

Controlling the vehicle is the key tosuccessful off-road driving. One ofthe best ways to control the vehicleis to control the speed.

{ WARNING

When driving off-road, bouncingand quick changes in directioncan easily throw you out ofposition. This could cause you tolose control and crash. You andyour passengers should alwayswear safety belts.

Before Driving Off-Road. Have all necessary maintenance

and service work completed.. Fuel the vehicle, fill fluid levels,

and check inflation pressure inall tires, including the spare,if equipped.

. Read all the information aboutall-wheel-drive vehicles in thismanual.

. Make sure all underbodyshields, if equipped, are properlyattached.

. Know the local laws that apply tooff-road driving.

To gain more ground clearance ifneeded, it may be necessary toremove the front fascia lowerair dam.

Notice: Operating the vehiclefor extended periods withoutthe front fascia lower air daminstalled can cause improper airflow to the engine. Re‐attach thefront fascia air dam after off-roaddriving.

Driving and Operating 9-9

When driving on hills:. Use a low gear and keep a firm

grip on the steering wheel.. Maintain a slow speed.. When possible, drive straight up

or down the hill.. Slow down when approaching

the top of the hill.. Use headlamps even during the

day to make the vehicle morevisible.

{ WARNING

Driving to the top of a hill at highspeed can cause an accident.There could be a drop-off,embankment, cliff, or evenanother vehicle. You couldbe seriously injured or killed.As you near the top of a hill,slow down and stay alert.

. Never go downhill forward orbackward with the transmissionin N (Neutral). The brakes couldoverheat and you could losecontrol.

. When driving down a hill, keepthe vehicle headed straightdown. Use a low gear becausethe engine will work with thebrakes to slow the vehicle andhelp keep the vehicle undercontrol.

{ WARNING

Heavy braking when going downa hill can cause your brakes tooverheat and fade. This couldcause loss of control and you orothers could be injured or killed.Apply the brakes lightly whendescending a hill and use a lowgear to keep vehicle speed undercontrol.

If the vehicle stalls on a hill:

1. Apply the brakes to stop thevehicle, and then apply theparking brake.

2. Shift into P (Park) and thenrestart the engine.. If driving uphill when

the vehicle stalls, shift toR (Reverse), release theparking brake, and backstraight down.

. Never try to turn the vehiclearound. If the hill is steepenough to stall the vehicle,it is steep enough to causeit to roll over.

9-10 Driving and Operating

. The vehicle can rollbackward quickly andyou could lose control.

. If driving downhill whenthe vehicle stalls, shift toa lower gear, release theparking brake, and drivestraight down the hill.

3. If the vehicle cannot be restartedafter stalling, set the parkingbrake, shift an automatictransmission into P (Park),and turn the vehicle off.

3.1. Leave the vehicle andseek help.

3.2. Stay clear of the path thevehicle would take if itrolled downhill.

. Avoid turns that take the vehicleacross the incline of the hill.A hill that can be driven straightup or down might be too steep todrive across. Driving across anincline puts more weight on thedownhill wheels which couldcause a downhill slide or arollover.

. Surface conditions can be aproblem. Loose gravel, muddyspots, or even wet grass cancause the tires to slip sideways,downhill. If the vehicle slipssideways, it can hit somethingthat will trip it – a rock, a rut,etc. – and roll over.

. Hidden obstacles can make thesteepness of the incline moresevere. If a rock is driven acrosswith the uphill wheels, or if thedownhill wheels drop into a rutor depression, the vehicle cantilt even more.

. If an incline must be drivenacross, and the vehicle starts toslide, turn downhill. This shouldhelp straighten out the vehicleand prevent the side slipping.

{ WARNING

Getting out of the vehicle onthe downhill side when stoppedacross an incline is dangerous.If the vehicle rolls over, you couldbe crushed or killed. Always getout on the uphill side of thevehicle and stay well clear ofthe rollover path.

Driving and Operating 9-11

Driving in Mud, Sand, Snow,or Ice

Use a low gear when driving inmud – the deeper the mud, thelower the gear. Keep the vehiclemoving to avoid getting stuck.

Traction changes when drivingon sand. On loose sand, suchas on beaches or sand dunes,the tires tend to sink into the sand.This affects steering, accelerating,and braking. Drive at a reducedspeed and avoid sharp turns orabrupt maneuvers.

Traction is reduced on hard packedsnow and ice and it is easy tolose control. Reduce vehicle speedwhen driving on hard packed snowand ice.

{ WARNING

Driving on frozen lakes, ponds,or rivers can be dangerous.Ice conditions vary greatly andthe vehicle could fall through theice; you and your passengerscould drown. Drive your vehicleon safe surfaces only.

Driving in Water

{ WARNING

Driving through rushing water canbe dangerous. Deep water cansweep your vehicle downstreamand you and your passengerscould drown. If it is only shallowwater, it can still wash away theground from under your tires.Traction could be lost, and thevehicle could roll over. Do notdrive through rushing water.

Notice: Do not drive throughstanding water if it is deepenough to cover the wheel hubs,axles or exhaust pipe. Deep watercan damage the axle and othervehicle parts.

If the standing water is not too deep,drive slowly through it. At fasterspeeds, water splashes on theignition system and the vehicle canstall. Stalling can also occur if youget the exhaust pipe under water.While the exhaust pipe is underwater, you will not be able to startthe engine. When going throughwater, the brakes get wet, andit might take longer to stop.See Driving on Wet Roads onpage 9‑12.

9-12 Driving and Operating

After Off-Road Driving

Remove any brush or debris thathas collected on the underbodyor chassis, or under the hood.These accumulations can bea fire hazard.

After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, steering,suspension, wheels, tires, andexhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.

More frequent maintenanceservice is required. Refer tothe Maintenance Schedule onpage 11‑3 for more information.

Driving on Wet RoadsRain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep‐standing or flowing water.

{ WARNING

Wet brakes can cause crashes.They might not work as well ina quick stop and could causepulling to one side. You couldlose control of the vehicle.

(Continued)

WARNING (Continued)

After driving through a largepuddle of water or a car/vehiclewash, lightly apply the brakepedal until the brakes worknormally.

Flowing or rushing water createsstrong forces. Driving throughflowing water could cause thevehicle to be carried away. If thishappens, you and other vehicleoccupants could drown. Do notignore police warnings and bevery cautious about trying todrive through flowing water.

Driving and Operating 9-13

Hydroplaning

Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the roadis wet enough and you are goingfast enough. When the vehicle ishydroplaning, it has little or nocontact with the road.

There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.

Other Rainy Weather Tips

Besides slowing down, other wetweather driving tips include:. Allow extra following distance.. Pass with caution.. Keep windshield wiping

equipment in good shape.. Keep the windshield washer fluid

reservoir filled.. Have good tires with proper

tread depth. See Tires onpage 10‑46.

. Turn off cruise control.

Highway HypnosisAlways be alert and pay attentionto your surroundings while driving.If you become tired or sleepy, finda safe place to park the vehicleand rest.

Other driving tips include:. Keep the vehicle well ventilated.. Keep the interior

temperature cool.. Keep your eyes moving — scan

the road ahead and to the sides.. Check the rearview mirror and

vehicle instruments often.

9-14 Driving and Operating

Hill and Mountain RoadsDriving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips fordriving in these conditions include:. Keep the vehicle serviced and in

good shape.. Check all fluid levels and brakes,

tires, cooling system, andtransmission.

. Shift to a lower gear when goingdown steep or long hills.

{ WARNING

If you do not shift down, thebrakes could get so hot that theywould not work well. You wouldthen have poor braking or evennone going down a hill. You couldcrash. Shift down to let the engineassist the brakes on a steepdownhill slope.

{ WARNING

Coasting downhill in N (Neutral)or with the ignition off isdangerous. The brakes will haveto do all the work of slowingdown and they could get so hotthat they would not work well.You would then have poor brakingor even none going down a hill.You could crash. Always have theengine running and the vehicle ingear when going downhill.

Driving and Operating 9-15

. Stay in your own lane. Do notswing wide or cut across thecenter of the road. Drive atspeeds that let you stay inyour own lane.

. Be alert on top of hills,something could be in yourlane (stalled car, accident).

. Pay attention to special roadsigns (falling rocks area, windingroads, long grades, passing orno-passing zones) and takeappropriate action.

Winter Driving

Driving on Snow or Ice

Drive carefully when there issnow or ice between the tires andthe road, creating less traction orgrip. Wet ice can occur at about0°C (32°F) when freezing rainbegins to fall, resulting in evenless traction. Avoid driving on wetice or in freezing rain until roadscan be treated with salt or sand.

Drive with caution, whatever thecondition. Accelerate gently sotraction is not lost. Accelerating tooquickly causes the wheels to spinand makes the surface under thetires slick, so there is even lesstraction.

Try not to break the fragile traction.If you accelerate too fast, the drivewheels will spin and polish thesurface under the tires even more.

The Antilock Brake System (ABS)on page 9‑35 improves vehiclestability during hard stops onslippery roads, but apply the brakessooner than when on dry pavement.

Allow greater following distance onany slippery road and watch forslippery spots. Icy patches canoccur on otherwise clear roads inshaded areas. The surface of acurve or an overpass can remainicy when the surrounding roadsare clear. Avoid sudden steeringmaneuvers and braking whileon ice.

Turn off cruise control on slipperysurfaces.

Blizzard Conditions

Being stuck in snow can be aserious situation. Stay with thevehicle unless there is help nearby.If possible, use the RoadsideAssistance Program (U.S. andCanada) on page 13‑8 or RoadsideAssistance Program (Mexico) onpage 13‑10. To get help and keepeveryone in the vehicle safe:. Turn on the hazard warning

flashers.. Tie a red cloth to an outside

mirror.

{ WARNING

Snow can trap engine exhaustunder the vehicle. This maycause exhaust gases to getinside. Engine exhaust containsCarbon Monoxide (CO) whichcannot be seen or smelled. It cancause unconsciousness and evendeath.

(Continued)

WARNING (Continued)

If the vehicle is stuck in the snow:. Clear away snow from aroundthe base of your vehicle,especially any that is blockingthe exhaust pipe.

. Check again from time totime to be sure snow doesnot collect there.

. Open a window about 5 cm(2 in) on the side of thevehicle that is away fromthe wind to bring in fresh air.

. Fully open the air outletson or under the instrumentpanel.

. Adjust the climate controlsystem to a setting thatcirculates the air insidethe vehicle and set the fanspeed to the highest setting.See Climate Control Systemin the Index.

WARNING (Continued)

For more information aboutcarbon monoxide, see EngineExhaust on page 9‑30.

Snow can trap exhaust gasesunder your vehicle. This cancause deadly CO (CarbonMonoxide) gas to get inside. COcould overcome you and kill you.You cannot see it or smell it, soyou might not know it is in yourvehicle. Clear away snow fromaround the base of your vehicle,especially any that is blockingthe exhaust.

Run the engine for short periodsonly as needed to keep warm,but be careful.

Driving and Operating 9-17

To save fuel, run the engine for onlyshort periods as needed to warmthe vehicle and then shut the engineoff and close the window most ofthe way to save heat. Repeat thisuntil help arrives but only when youfeel really uncomfortable from thecold. Moving about to keep warmalso helps.

If it takes some time for help toarrive, now and then when you runthe engine, push the acceleratorpedal slightly so the engineruns faster than the idle speed.This keeps the battery charged torestart the vehicle and to signal forhelp with the headlamps. Do thisas little as possible to save fuel.

If the Vehicle Is StuckSlowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.

If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. See TractionControl System (TCS) onpage 9‑37.

{ WARNING

If the vehicle's tires spin at highspeed, they can explode, andyou or others could be injured.The vehicle can overheat,causing an engine compartmentfire or other damage. Spin thewheels as little as possible andavoid going above 55 km/h(35 mph).

For information about using tirechains on the vehicle, see TireChains on page 10‑66.

Rocking the Vehicle to Getit Out

Turn the steering wheel left andright to clear the area around thefront wheels. Turn off any tractionsystem. Shift back and forthbetween R (Reverse) and a forwardgear, spinning the wheels as little aspossible. To prevent transmissionwear, wait until the wheels stopspinning before shifting gears.Release the accelerator pedalwhile shifting, and press lightly onthe accelerator pedal when thetransmission is in gear. Slowlyspinning the wheels in the forwardand reverse directions causes arocking motion that could free thevehicle. If that does not get thevehicle out after a few tries, it mightneed to be towed out. If the vehicledoes need to be towed out, seeTowing the Vehicle on page 10‑80.

Vehicle Load LimitsIt is very important to knowhow much weight the vehiclecan carry. This weight is calledthe vehicle capacity weightand includes the weight ofall occupants, cargo and allnonfactory‐installed options.Two labels on the vehicleshow how much weight itmay properly carry, the Tireand Loading Information labeland the Certification label.

{ WARNING

Do not load the vehicle anyheavier than the GrossVehicle Weight Rating(GVWR), or either themaximum front or rear GrossAxle Weight Rating (GAWR).This can cause systems tobreak and change the way thevehicle handles. This couldcause loss of control and acrash. Overloading can alsoshorten the life of the vehicle.

Tire and Loading InformationLabel

Label Example

A vehicle specific Tire andLoading Information labelis attached to the vehicle'scenter pillar (B-pillar). Withthe driver's door open, youwill find the label attachednear the door lock post.

Page 233: 2012 GMC Terrain Owner Manual M - Owner Center Home GMC Terrain Owner Manual M Vehicle Care..... 10-1 General ... when you need to see a service manual for additional instructions

Black plate (19,1)GMC Terrain Owner Manual (Include Mex) - 2012

Driving and Operating 9-19

The Tire and LoadingInformation label shows thenumber of occupant seatingpositions (A), and the maximumvehicle capacity weight (B) inkilograms and pounds.

The Tire and LoadingInformation label also showsthe tire size of the originalequipment tires (C) and therecommended cold tire inflationpressures (D). For moreinformation on tires and inflationsee Tires on page 10‑46 andTire Pressure on page 10‑53.

There is also important loadinginformation on the Certificationlabel. It tells you the GrossVehicle Weight Rating (GVWR)and the Gross Axle WeightRating (GAWR) for the frontand rear axle. See “CertificationLabel” later in this section.

Steps for Determining CorrectLoad Limit

1. Locate the statement“The combined weight ofoccupants and cargo shouldnever exceed XXX kg orXXX lbs” on your vehicle'splacard.

2. Determine the combinedweight of the driver andpassengers that will beriding in your vehicle.

3. Subtract the combinedweight of the driver andpassengers from XXX kgor XXX lbs.

4. The resulting figure equalsthe available amount of cargoand luggage load capacity.For example, if the “XXX”amount equals 1400 lbsand there will be five 150 lbpassengers in your vehicle,the amount of available cargoand luggage load capacityis 650 lbs (1400 − 750(5 x 150) = 650 lbs).

5. Determine the combinedweight of luggage and cargobeing loaded on the vehicle.That weight may not safelyexceed the available cargoand luggage load capacitycalculated in Step 4.

9-20 Driving and Operating

6. If your vehicle will be towinga trailer, the load from yourtrailer will be transferred toyour vehicle. Consult thismanual to determine how thisreduces the available cargoand luggage load capacity ofyour vehicle.

See Trailer Towing on page 9‑64for important information ontowing a trailer, towing safetyrules and trailering tips. Example 1

A. Vehicle Capacity Weightfor Example 1 = 453 kg(1,000 lbs).

B. Subtract OccupantWeight @ 68 kg(150 lbs) × 2 = 136 kg(300 lbs).

C. Available Occupant andCargo Weight = 317 kg(700 lbs).

Example 2

A. Vehicle Capacity Weightfor Example 2 = 453 kg(1,000 lbs).

B. Subtract OccupantWeight @ 68 kg(150 lbs) × 5 = 340 kg(750 lbs).

C. Available CargoWeight = 113 kg (250 lbs).

B. Subtract OccupantWeight @ 91 kg(200 lbs) × 5 = 453 kg(1,000 lbs).

C. Available CargoWeight = 0 kg (0 lbs).

Refer to the vehicle's Tire andLoading Information label forspecific information about thevehicle's capacity weight andseating positions. The combinedweight of the driver, passengers,and cargo should never exceedthe vehicle's capacity weight.

Certification Label

Label Example

A vehicle-specific Certificationlabel is attached to the lowercenter pillar on the driver side of

the vehicle or on the rear edgeof the driver door. The labelshows the size of the vehicle'soriginal tires and the inflationpressures needed to obtain thegross weight capacity of thevehicle. This is called GrossVehicle Weight Rating (GVWR).The GVWR includes the weightof the vehicle, all occupants,fuel, and cargo.

The Certification/Tire label alsotells you the maximum weightsfor the front and rear axles,called Gross Axle WeightRating (GAWR). To find out theactual loads on the front andrear axles, you need to go toa weigh station and weigh thevehicle. Your dealer can helpyou with this. Be sure to spreadout the load equally on bothsides of the center line.

9-22 Driving and Operating

Never exceed the GVWR for thevehicle, or the GAWR for eitherthe front or rear axle.

If the vehicle is carrying aheavy load, it should be spreadout. See “Steps for DeterminingCorrect Load Limit” earlier in thissection.

{ WARNING

Do not load the vehicleany heavier than theGross Vehicle WeightRating (GVWR), or either themaximum front or rear GrossAxle Weight Rating (GAWR).This can cause systems tobreak and change the way thevehicle handles. This couldcause loss of control and acrash. Overloading can alsoshorten the life of the vehicle.

Your warranty does not coverparts or components that failbecause of overloading.

The label will help you decidehow much cargo and installedequipment your vehicle cancarry.

Using heavier suspensioncomponents to get addeddurability might not change yourweight ratings. Ask your dealerto help you load your vehiclethe right way.

If you put things inside yourvehicle – like suitcases,tools, packages, or anythingelse – they will go as fast asthe vehicle goes. If you have tostop or turn quickly, or if thereis a crash, they will keep going.

{ WARNING

Things inside the vehicle canstrike and injure people in asudden stop or turn, or in acrash.

. Put things in the cargoarea of the vehicle. In thecargo area, put them asfar forward as possible.Try to spread the weightevenly.

The vehicle has aComputer-ControlledCranking System. This featureassists in starting the engineand protects components.If the ignition key is turned tothe START position, and thenreleased when the enginebegins cranking, the enginewill continue cranking for a fewseconds or until the vehiclestarts. If the engine does notstart and the key is held inSTART for many seconds,cranking will be stopped after15 seconds to prevent crankingmotor damage. To preventgear damage, this system alsoprevents cranking if the engineis already running. Enginecranking can be stopped byturning the ignition switchto ACC/ACCESSORY orLOCK/OFF.

Notice: Cranking the engine forlong periods of time, by returningthe key to the START positionimmediately after cranking hasended, can overheat and damagethe cranking motor, and drain thebattery. Wait at least 15 secondsbetween each try, to let thecranking motor cool down.

2. If the engine does not start after5 to 10 seconds, especially invery cold weather (below −18°Cor 0°F), it could be flooded withtoo much gasoline. Push theaccelerator pedal all the wayto the floor and hold it there asyou hold the key in START for amaximum of 15 seconds. Wait atleast 15 seconds between eachtry, to allow the cranking motorto cool. When the engine starts,let go of the key and accelerator.

If the vehicle starts briefly butthen stops again, repeat theprocedure. This clears the extragasoline from the engine. Do notrace the engine immediatelyafter starting it. Operate theengine and transmission gentlyuntil the oil warms up andlubricates all moving parts.

Drive Systems

All-Wheel DriveVehicles with this feature alwayssend engine power to all fourwheels. It is fully automatic,and adjusts itself as neededfor road conditions.

When using a compact sparetire on an AWD vehicle, thesystem automatically detects thecompact spare and disables AWD.To restore AWD operation andprevent excessive wear on thesystem, replace the compact sparewith a full-size tire as soon aspossible. See Compact Spare Tireon page 10‑75 for more information.

Brakes

Antilock BrakeSystem (ABS)This vehicle has the AntilockBrake System (ABS), an advancedelectronic braking system that helpsprevent a braking skid.

When the engine is started and thevehicle begins to drive away, ABSchecks itself. A momentary motor orclicking noise might be heard whilethis test is going on, and it mighteven be noticed that the brakepedal moves a little. This is normal.

If there is a problem with ABS, thiswarning light stays on. See AntilockBrake System (ABS) Warning Lighton page 5‑17.

If driving safely on a wet roadand it becomes necessary toslam on the brakes and continuebraking to avoid a sudden obstacle,a computer senses that the wheelsare slowing down. If one of thewheels is about to stop rolling,the computer will separately workthe brakes at each wheel.

ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpthe driver steer around the obstaclewhile braking hard.

As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.

Remember: ABS does not changethe time needed to get a foot upto the brake pedal or alwaysdecrease stopping distance.

9-36 Driving and Operating

If you get too close to the vehiclein front of you, there will not beenough time to apply the brakesif that vehicle suddenly slows orstops. Always leave enough roomup ahead to stop, even with ABS.

Using ABS

Do not pump the brakes. Just holdthe brake pedal down firmly and letABS work. You might hear the ABSpump or motor operating and feelthe brake pedal pulsate, but this isnormal.

Braking in Emergencies

ABS allows the driver to steer andbrake at the same time. In manyemergencies, steering can helpmore than even the very bestbraking.

Parking Brake

To set the parking brake, hold theregular brake pedal down, thenpush the parking brake pedal down.

If the ignition is on, the brakesystem warning light will come on.See Brake System Warning Light onpage 5‑16.

Notice: Driving with the parkingbrake on can overheat the brakesystem and cause prematurewear or damage to brake systemparts. Make sure that the parkingbrake is fully released and thebrake warning light is off beforedriving.

To release the parking brake, holdthe regular brake pedal down, thenpush down momentarily on theparking brake pedal until you feelthe pedal release. Slowly pull yourfoot up off the park brake pedal.If the parking brake is not releasedwhen you begin to drive, the brakesystem warning light will be on anda chime will sound warning you thatthe parking brake is still on.

Brake AssistThis vehicle has a brake assistfeature designed to assist thedriver in stopping or decreasingvehicle speed in emergency drivingconditions. This feature uses thestability system hydraulic brakecontrol module to supplementthe power brake system underconditions where the driver hasquickly and forcefully applied thebrake pedal in an attempt to quicklystop or slow down the vehicle.The stability system hydraulic brakecontrol module increases brakepressure at each corner of thevehicle until the ABS activates.Minor brake pedal pulsation orpedal movement during this timeis normal and the driver shouldcontinue to apply the brake pedalas the driving situation dictates.The brake assist feature willautomatically disengage whenthe brake pedal is released orbrake pedal pressure is quicklydecreased.

Hill Start Assist (HSA)This vehicle has a Hill Start Assist(HSA) feature, which may be usefulwhen the vehicle is stopped on agrade. This feature is designed toprevent the vehicle from rolling,either forward or rearward, duringvehicle drive off. After the drivercompletely stops and holds thevehicle in a complete standstill ona grade, HSA will be automaticallyactivated. During the transitionperiod between when the driverreleases the brake pedal and startsto accelerate to drive off on a grade,HSA holds the braking pressureto ensure that there is no rolling.The brakes will automaticallyrelease when the accelerator pedalis applied within the two‐secondwindow. It will not activate if thevehicle is in a drive gear and facingdownhill or if the vehicle is facinguphill and in R (Reverse).

Ride Control Systems

Traction ControlSystem (TCS)The vehicle has a Traction ControlSystem (TCS) that limits wheel spin.On a front-wheel-drive vehicle, thesystem operates if it senses thatone or both of the front wheelsare spinning or beginning to losetraction. On an All-Wheel-Drive(AWD) vehicle, the system willoperate if it senses that any of thewheels are spinning or beginning tolose traction. When this happens,the system brakes the spinningwheel(s) and/or reduces enginepower to limit wheel spin.

The system may be heard or feltwhile it is working, but this isnormal.

If the FCA system does not seem tooperate properly, clean the outsideof the windshield area in front of thecamera sensor before consideringtaking the vehicle in for service.

Ultrasonic Parking AssistFor vehicles with the UltrasonicRear Parking Assist (URPA) system,it assists the driver with parkingand avoiding objects while inR (Reverse). URPA operates atspeeds less than 8 km/h (5 mph),and the sensors on the rear bumperdetect objects up to 2.5 m (8 ft)behind the vehicle, and at least20 cm (8 in) off the ground.

{ WARNING

The URPA system does notdetect pedestrians, bicyclists,animals, or any other objectslocated below the bumper or thatare too close or too far from thevehicle. To prevent injury, death,or vehicle damage, even withURPA, always check behind thevehicle and check all mirrorsbefore backing.

How the System Works

URPA comes on automaticallywhen the shift lever is moved intoR (Reverse). A single tone soundsto indicate the system is working.

URPA operates only at speeds lessthan 8 km/h (5 mph).

An obstacle is indicated by audiblebeeps. The interval between thebeeps becomes shorter as thevehicle gets closer to the obstacle.When the distance is less than30 cm (12 in) the beeping is acontinuous tone for five seconds.

To be detected, objects must be atleast 20 cm (8 in) off the ground andbelow liftgate level. Objects mustalso be within 2.5 m (8 ft) from therear bumper. The distance objectscan be detected may be less duringwarmer or humid weather.

Vehicles that have a FlexFuel badgeand a yellow fuel cap can use eitherunleaded gasoline or ethanol fuelcontaining up to 85% ethanol (E85).See Fuel E85 (85% Ethanol) onpage 9‑56. For all other vehicles,use only the unleaded gasolinedescribed under RecommendedFuel on page 9‑54.

Recommended FuelUse regular unleaded gasolinewith a posted octane rating of 87 orhigher. If the octane rating is lessthan 87, an audible knocking noise,commonly referred to as sparkknock, might be heard when driving.If this occurs, use a gasoline ratedat 87 octane or higher as soonas possible. If heavy knocking isheard when using gasoline ratedat 87 octane or higher, the engineneeds service.

Gasoline Specifications(U.S. and Canada Only)At a minimum, gasoline shouldmeet ASTM specificationD 4814 in the United Statesor CAN/CGSB‐3.5 or 3.511 inCanada. Some gasolines containan octane-enhancing additive calledmethylcyclopentadienyl manganesetricarbonyl (MMT). We recommendagainst the use of gasolinescontaining MMT. See Fuel Additiveson page 9‑55 for additionalinformation.

California FuelRequirementsIf the vehicle is certified to meetCalifornia Emissions Standards,it is designed to operate on fuelsthat meet California specifications.See the underhood emission controllabel. If this fuel is not available instates adopting California EmissionsStandards, the vehicle will operatesatisfactorily on fuels meetingfederal specifications, but emissioncontrol system performance mightbe affected. The malfunctionindicator lamp could turn on and thevehicle might fail a smog‐check test.See Malfunction Indicator Lamp onpage 5‑13. If this occurs, return toyour authorized dealer for diagnosis.If it is determined that the conditionis caused by the type of fuel used,repairs might not be covered by thevehicle warranty.

Fuels in ForeignCountriesNever use leaded gasoline or anyother fuel not recommended in theprevious text on fuel. Costly repairscaused by use of improper fuelwould not be covered by the vehiclewarranty.

To check the fuel availability, askan auto club, or contact a major oilcompany that does business in thecountry where you will be driving.

Fuel AdditivesTo provide cleaner air, all gasolinesin the United States are nowrequired to contain additives thathelp prevent engine and fuel systemdeposits from forming, allowing theemission control system to workproperly. In most cases, nothingshould have to be added to thefuel. However, some gasolinescontain only the minimum amountof additive required to meet U.S.Environmental Protection Agencyregulations. To help keep fuelinjectors and intake valves cleanand avoid problems due to dirtyinjectors or valves, look for gasolinethat is advertised as TOP TIERDetergent Gasoline. Look for theTOP TIER label on the fuel pumpto ensure gasoline meets enhanceddetergency standards developedby the auto companies.

For customers who do not useTOP TIER Detergent Gasolineregularly, one bottle of GM FuelSystem Treatment PLUS, added tothe fuel tank at every engine oilchange, can help clean depositsfrom fuel injectors and intakevalves. GM Fuel System TreatmentPLUS is the only gasoline additiverecommended by General Motors.It is available at your dealer.

Gasolines containing oxygenates,such as ethers and ethanol,and reformulated gasolinesmight be available in your area.We recommend that you use thesegasolines, if they comply with thespecifications described earlier.However, E85 (85% ethanol) andother fuels containing more than15% ethanol must not be used invehicles that were not designedfor those fuels.

Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.

Some gasolines that arenot reformulated for lowemissions can contain anoctane-enhancing additivecalled methylcyclopentadienylmanganese tricarbonyl (MMT);ask the attendant where youbuy gasoline whether the fuelcontains MMT. We recommendagainst the use of such gasolines.Fuels containing MMT can reducespark plug life and affect emissioncontrol system performance.The malfunction indicator lampmight turn on. If this occurs,return to your dealer for service.

Fuel E85 (85% Ethanol)Vehicles that have a FlexFuel badgeand a yellow fuel cap can use eitherunleaded gasoline or ethanol fuelcontaining up to 85% ethanol (E85).For all other vehicles, use only theunleaded gasoline described underRecommended Fuel on page 9‑54.

We encourage the use of E85 invehicles that are designed to use it.The ethanol in E85 is a “renewable”fuel, meaning it is made fromrenewable sources such as cornand other crops.

Many service stations will not havean 85% ethanol fuel (E85) pumpavailable. The U.S. Departmentof Energy has an alternative fuelswebsite (www.afdc.energy.gov/afdc/locator/stations/) that can help youfind E85 fuel. Those stations thatdo have E85 should have a labelindicating ethanol content. Do notuse the fuel if the ethanol contentis greater than 85%.

Driving and Operating 9-57

At a minimum, E85 should meetASTM Specification D 5798 orCGSB Specification 3.512. Fillingthe tank with fuel mixtures thatdo not meet ASTM or CGSBspecifications can affect driveabilityand could cause the malfunctionindicator lamp to come on. As theoutside temperature approachesfreezing, ethanol fuel distributorsshould supply winter grade ethanol,the same as with unleadedgasoline.

The starting characteristics ofE85 fuel make it unsuitable for usewhen temperatures fall below −18°C(0°F). In the range of −18°C (0°F) to0°C (32°F), it may take more time tostart the engine.

It is best not to alternaterepeatedly between gasoline andE85. If you do switch fuels, it isrecommended that you add asmuch fuel as possible — do notadd less than 11 L (3 gal) whenrefueling. You should drive thevehicle immediately after refuelingfor at least 11 km (7 mi) to allowthe vehicle to adapt to the changein ethanol concentration.

E85 has less energy per liter(gallon) than gasoline, so you willneed to refill the fuel tank moreoften when using E85 than whenyou are using gasoline. See Fillingthe Tank on page 9‑58.

Notice: Some additives are notcompatible with E85 fuel and canharm the vehicle's fuel system.Do not add anything to E85.Damage caused by additiveswould not be covered by thevehicle warranty.

Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.

Driving and Operating 9-61

The following information hasimportant trailering tips and rulesfor your safety and that of yourpassengers. Read this sectioncarefully before pulling a trailer.

Pulling a Trailer

Here are some important points:. There are many laws, including

speed limit restrictions that applyto trailering. Check for legalrequirements with state orprovincial police.

. Do not tow a trailer at all duringthe first 1 600 km (1,000 miles)the new vehicle is driven.The engine, axle or otherparts could be damaged.

. During the first 800 km(500 miles) that a trailer istowed, do not drive over 80 km/h(50 mph) and do not make startsat full throttle. This reduces wearon the vehicle.

. The vehicle can tow inD (Drive). Use a lower gear ifthe transmission shifts too often.

. Do not use the Fuel Saver Modewhen towing.

. Obey speed limit restrictions.Do not drive faster than themaximum posted speed fortrailers, or no more than 90 km/h(55 mph), to reduce wear on thevehicle.

. For vehicles with the UltraRear Parking Assist (URPA)system, turn the system off whentowing a trailer. If the tow baris installed while not towinga trailer, change the URPAsystem to the “Tow Bar” setting.See Ultrasonic Parking Assist onpage 9‑46 for more information.

Driving with a Trailer

Towing a trailer requires experience.Get familiar with handling andbraking with the added trailerweight. The vehicle is now longerand not as responsive as thevehicle is by itself.

Check all trailer hitch partsand attachments, safety chains,electrical connectors, lamps, tiresand mirror adjustments. If the trailerhas electric brakes, start the vehicleand trailer moving and then applythe trailer brake controller by handto be sure the brakes are working.

During the trip, check regularly to besure that the load is secure, and thelamps and trailer brakes are workingproperly.

Page 276: 2012 GMC Terrain Owner Manual M - Owner Center Home GMC Terrain Owner Manual M Vehicle Care..... 10-1 General ... when you need to see a service manual for additional instructions

Black plate (62,1)GMC Terrain Owner Manual (Include Mex) - 2012

9-62 Driving and Operating

Towing with a Stability ControlSystem

When towing, the sound of thestability control system might beheard. The system is reacting to thevehicle movement caused by thetrailer, which mainly occurs duringcornering. This is normal whentowing heavier trailers.

Following Distance

Stay at least twice as far behind thevehicle ahead as you would whendriving the vehicle without a trailer.This can help to avoid situationsthat require heavy braking andsudden turns.

Passing

More passing distance is neededwhen towing a trailer. Because therig is longer, it is necessary to gofarther beyond the passed vehiclebefore returning to the lane.

Backing Up

Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that handto the left. To move the trailer tothe right, move your hand to theright. Always back up slowly and,if possible, have someoneguide you.

Making Turns

Notice: Making very sharp turnswhile trailering could cause thetrailer to come in contact withthe vehicle. The vehicle couldbe damaged. Avoid making verysharp turns while trailering.

When turning with a trailer, makewider turns than normal so thetrailer will not strike soft shoulders,curbs, road signs, trees or otherobjects. Use the turn signal well inadvance and avoid jerky or suddenmaneuvers.

Turn Signals When Towing aTrailer

The turn signal indicators on theinstrument panel flash wheneversignaling a turn or lane change.Properly hooked up, the trailerlamps also flash, telling otherdrivers the vehicle is turning,changing lanes or stopping.

When towing a trailer, the arrows onthe instrument panel flash for turnseven if the bulbs on the trailer areburned out. Check occasionally tobe sure the trailer bulbs are stillworking.

Driving on Grades

Reduce speed and shift to alower gear before starting downa long or steep downgrade. If thetransmission is not shifted down,the brakes might have to be usedso much that they would get hotand no longer work well.

Page 277: 2012 GMC Terrain Owner Manual M - Owner Center Home GMC Terrain Owner Manual M Vehicle Care..... 10-1 General ... when you need to see a service manual for additional instructions

Black plate (63,1)GMC Terrain Owner Manual (Include Mex) - 2012

Driving and Operating 9-63

The vehicle can tow in D (Drive).Use a lower gear if the transmissionshifts too often.

When towing at high altitude onsteep uphill grades, engine coolantwill boil at a lower temperature thanat normal altitudes. If the engine isturned off immediately after towingat high altitude on steep uphillgrades, the vehicle may showsigns similar to engine overheating.To avoid this, let the engine runwhile parked, preferably on levelground, with the transmission inP (Park) for a few minutes beforeturning the engine off. If theoverheat warning comes on, seeEngine Overheating on page 10‑21.

Parking on Hills

{ WARNING

Parking the vehicle on a hillwith the trailer attached can bedangerous. If something goeswrong, the rig could start to move.People can be injured, and boththe vehicle and the trailer can bedamaged. When possible, alwayspark the rig on a flat surface.

If parking the rig on a hill:

1. Press the brake pedal, butdo not shift into P (Park) yet.Turn the wheels into the curb iffacing downhill or into traffic iffacing uphill.

2. Have someone place chocksunder the trailer wheels.

3. When the wheel chocks are inplace, release the brake pedaluntil the chocks absorb the load.

4. Reapply the brake pedal.Then apply the parking brakeand shift into P (Park).

5. Release the brake pedal.

Leaving After Parking on a Hill

1. Apply and hold the brake pedal.

2. Start the engine.

3. Shift into a gear.

4. Release the parking brake.

5. Let up on the brake pedal.

6. Drive slowly until the trailer isclear of the chocks.

7. Stop and have someone pick upand store the chocks.

Maintenance When TrailerTowing

The vehicle needs service moreoften when pulling a trailer. See thismanual's Maintenance Scheduleor Index for more information.Things that are especially importantin trailer operation are automatictransmission fluid, engine oil, axlelubricant, belts, cooling system andbrake system. Inspect these beforeand during the trip.

Check periodically to see that allhitch nuts and bolts are tight.

Engine Cooling When TrailerTowing

The cooling system may temporarilyoverheat during severe operatingconditions. See Engine Overheatingon page 10‑21.

Trailer TowingBefore pulling a trailer, there arethree important considerations thathave to do with weight:. The weight of the trailer. The weight of the trailer tongue. The total weight on the vehicle's

tires

Weight of the Trailer

How heavy can a trailer safely be?

Speed, altitude, road grades,outside temperature, specialequipment, and the amount oftongue weight the vehicle can carrymust be considered. See “Weightof the Trailer Tongue” later in thissection for more information.

Maximum trailer weight is calculatedassuming only the driver is inthe tow vehicle and it has all therequired trailering equipment.The weight of additional optionalequipment, passengers and cargo inthe tow vehicle must be subtractedfrom the maximum trailer weight.

Use the following chart to determinehow much the vehicle can weigh,based upon the vehicle model andoptions.

† For trailers without trailer brakes the maximum trailer weight is 454 kg(1,000 lbs). See Towing Equipment on page 9‑66 for more information.

*The Gross Combination WeightRating (GCWR) is the totalallowable weight of the completelyloaded vehicle and trailer includingany passengers, cargo, equipmentand conversions. The GCWR for thevehicle should not be exceeded.

Ask your dealer for ourtrailering information or advice.See Customer Assistance Offices(U.S. and Canada) on page 13‑5or Customer Assistance Offices(Mexico) on page 13‑6 for moreinformation.

Weight of the Trailer Tongue

The tongue load (A) of any traileris an important weight to measurebecause it affects the total grossweight of the vehicle. The GrossVehicle Weight (GVW) includesthe curb weight of the vehicle,any cargo carried in it, and thepeople who will be riding in thevehicle. If there are a lot of options,equipment, passengers or cargo inthe vehicle, it will reduce the tongueweight the vehicle can carry, whichwill also reduce the trailer weight thevehicle can tow. If towing a trailer,the tongue load must be added tothe GVW because the vehicle willbe carrying that weight, too. SeeVehicle Load Limits on page 9‑18.

Page 280: 2012 GMC Terrain Owner Manual M - Owner Center Home GMC Terrain Owner Manual M Vehicle Care..... 10-1 General ... when you need to see a service manual for additional instructions

Black plate (66,1)GMC Terrain Owner Manual (Include Mex) - 2012

9-66 Driving and Operating

If a weight-carrying hitch or aweight-distributing hitch is beingused, the trailer tongue (A) shouldweigh 10 to 15 percent of the totalloaded trailer weight (B).

After loading the trailer, weighthe trailer and then the tongue,separately, to see if the weights areproper. If they are not, adjustmentsmight be made by moving someitems around in the trailer.

Trailering may be limited by thevehicle's ability to carry tongueweight. Tongue weight cannot causethe vehicle to exceed the GVWR

(Gross Vehicle Weight Rating)or the RGAWR (Rear Gross AxleWeight Rating). The effect ofadditional weight may reduce thetrailering capacity more than thetotal of the additional weight.

It is important that the vehicledoes not exceed any of itsratings — GCWR, GVWR, RGAWR,Maximum Trailer Rating or TongueWeight. The only way to be sure it isnot exceeding any of these ratingsis to weigh the vehicle and trailer.

Total Weight on the Vehicle'sTires

Inflate the vehicle's tires tothe upper limit for cold tires.These numbers can be found onthe Certification label or see VehicleLoad Limits on page 9‑18 for moreinformation. Do not go over theGVW limit for the vehicle, or theGAWR, including the weight of thetrailer tongue. If using a weightdistributing hitch, do not go over therear axle limit before applying theweight distribution spring bars.

Towing Equipment

Hitches

Use the correct hitch equipment.See your dealer or a hitch dealerfor assistance.. The rear bumper on the vehicle

is not intended for hitches.Do not attach rental hitchesor other bumper-type hitchesto it. Use only a frame-mountedhitch that does not attach to thebumper.

. Will any holes be made in thebody of the vehicle when thetrailer hitch is installed? If thereare, seal the holes when thehitch is removed. If the holesare not sealed, dirt, water, anddeadly carbon monoxide (CO)from the exhaust can get into thevehicle. See Engine Exhaust onpage 9‑30.

Driving and Operating 9-67

Safety Chains

Always attach chains between thevehicle and the trailer. Cross thesafety chains under the tongueof the trailer to help prevent thetongue from contacting the road if itbecomes separated from the hitch.Leave enough slack so the rig canturn. Never allow safety chains todrag on the ground.

Trailer Brakes

Does the trailer have its ownbrakes? Be sure to read and followthe instructions for the trailer brakesso they are installed, adjusted, andmaintained properly.

Because the vehicle has antilockbrakes, do not tap into the vehicle'sbrake system. If this is done, bothbrake systems will not work well,or at all.

Trailer SwayControl (TSC)The vehicle has a Trailer SwayControl (TSC) feature as part of theStabiliTrak system. If TSC detectsthat the trailer is swaying, thevehicle's brakes are automaticallyapplied.

When TSC is applying the brakes,the TCS/StabiliTrak indicator lightflashes to notify the driver to reducespeed. If the trailer continues tosway, StabiliTrak will reduce enginetorque to help slow the vehicle.

TSC will not function if StabiliTrak isturned off. See StabiliTrak® Systemon page 9‑39 for more information.

Engine OilTo ensure proper engineperformance and long life, carefulattention must be paid to engineoil. Following these simple, butimportant steps will help protectyour investment:. Always use engine oil approved

to the proper specification andof the proper viscosity grade.See “Selecting the Right EngineOil” in this section.

. Check the engine oil levelregularly and maintain theproper oil level. See “CheckingEngine Oil” and “When to AddEngine Oil” in this section.

. Change the engine oil at theappropriate time. See EngineOil Life System on page 10‑13.

. Always dispose of engine oilproperly. See “What to Do withUsed Oil” in this section.

Checking Engine Oil

It is a good idea to check theengine oil level at each fuel fill.In order to get an accuratereading, the vehicle must beon level ground. The engine oildipstick handle is a yellow loop.See Engine Compartment Overviewon page 10‑6 for the location ofthe engine oil dipstick.

Obtaining an accurate oil levelreading is essential:

1. If the engine has been runningrecently, turn off the engine andallow several minutes for the oilto drain back into the oil pan.Checking the oil level too soonafter engine shutoff will notprovide an accurate oil levelreading.

2. Pull out the dipstick and cleanit with a paper towel or cloth,then push it back in all the way.Remove it again, keeping thetip down, and check the level.

Vehicle Care 10-11

When to Add Engine Oil

2.4L L4 Engine

3.0L V6 Engine

If the oil is below the cross-hatchedarea at the tip of the dipstick, add1 L (1 qt) of the recommendedoil and then recheck the level.

See “Selecting the Right EngineOil” in this section for anexplanation of what kind of oil touse. For engine oil crankcasecapacity, see Capacities andSpecifications on page 12‑2.

Notice: Do not add too much oil.Oil levels above or below theacceptable operating rangeshown on the dipstick are harmfulto the engine. If you find thatyou have an oil level above theoperating range, i.e., the enginehas so much oil that the oil levelgets above the cross-hatchedarea that shows the properoperating range, the engine couldbe damaged. You should drainout the excess oil or limit drivingof the vehicle and seek a serviceprofessional to remove theexcess amount of oil.

See Engine Compartment Overviewon page 10‑6 for the location of theengine oil fill cap.

Add enough oil to put the levelsomewhere in the proper operatingrange. Push the dipstick all the wayback in when through.

Selecting the Right Engine Oil

Selecting the right engine oildepends on both the proper oilspecification and viscosity grade.See Recommended Fluids andLubricants on page 11‑12.

10-12 Vehicle Care

Specification

Use and ask for licensed engineoils with the dexos1™ approvedcertification mark. Engine oilsmeeting the requirements for thevehicle should have the dexos1approved certification mark.This certification mark indicatesthat the oil has been approvedto the dexos1 specification.

Notice: Failure to use therecommended engine oil orequivalent can result in enginedamage not covered by thevehicle warranty. Check withyour dealer or service provideron whether the oil is approvedto the dexos1 specification.

Viscosity Grade

SAE 5W‐30 is the best viscositygrade for the vehicle. Do not useother viscosity grade oils such asSAE 10W‐30, 10W‐40, or 20W‐50.

If in an area of extreme cold, wherethe temperature falls below −20°F(−29°C), an SAE 0W‐30 oil shouldbe used. An oil of this viscositygrade will provide easier coldstarting for the engine at extremelylow temperatures. When selectingan oil of the appropriate viscositygrade, always select an oil thatmeets the dexos1 specification orequivalent. See “Specification” formore information.

Engine Oil Additives/EngineOil Flushes

Do not add anything to the oil.The recommended oils with thedexos specification and displayingthe dexos certification mark are allthat is needed for good performanceand engine protection.

Engine oil system flushes are notrecommended and could causeengine damage not covered bythe vehicle warranty.

What to Do with Used Oil

Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or ragscontaining used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.

Vehicle Care 10-13

Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all theoil from the filter before disposal.Never dispose of oil by puttingit in the trash or pouring it on theground, into sewers, or into streamsor bodies of water. Recycle it bytaking it to a place that collectsused oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is basedon a combination of factors whichinclude engine revolutions, enginetemperature, and miles driven.Based on driving conditions, themileage at which an oil change isindicated can vary considerably.For the oil life system to workproperly, the system must be resetevery time the oil is changed.

When the system has calculatedthat oil life has been diminished,it indicates that an oil change isnecessary. A CHANGE ENGINEOIL SOON message comes on.See Engine Oil Messages onpage 5‑28. Change the oil as soonas possible within the next 1 000 km(600 mi). It is possible that, if drivingunder the best conditions, the oil lifesystem might indicate that an oilchange is not necessary for up to ayear. The engine oil and filter mustbe changed at least once a yearand, at this time, the system mustbe reset. Your dealer has trainedservice people who will perform thiswork and reset the system. It is alsoimportant to check the oil regularlyover the course of an oil draininterval and keep it at the properlevel.

If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.

How to Reset the Engine OilLife System

Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. To reset thesystem:

1. Turn the ignition to ON/RUN,with the engine off.

2. Press the DIC MENUbutton to display the VehicleInformation menu.

3. Press either the up or downarrows to view REMAININGOIL LIFE.

4. Press the SET/CLR button until100% is displayed.

5. Turn the key to LOCK/OFF.

What to Use

To determine what kind of fluid touse, refer to Recommended Fluidsand Lubricants on page 11‑12.Always use the proper fluid.

Notice: Use of the incorrect fluidmay damage the vehicle and thedamages may not be covered bythe vehicle's warranty. Alwaysuse the correct fluid listed inRecommended Fluids andLubricants on page 11‑12.

Washer Fluid

What to Use

Read the manufacturer'sinstructions before refillingthe windshield washer fluid.If operating the vehicle in anarea where the temperaturemay fall below freezing, usea fluid that has sufficient protectionagainst freezing.

Adding Washer Fluid

Open the cap with the washersymbol on it and add washer fluiduntil full. See Engine CompartmentOverview on page 10‑6 for reservoirlocation.

Notice. When using concentratedwasher fluid, follow themanufacturer's instructionsfor adding water.

. Do not mix water withready-to-use washer fluid.Water can cause the solutionto freeze and damage thewasher fluid tank and otherparts of the washer system.Also, water does not cleanas well as washer fluid.

. Fill the washer fluid tankonly three-quarters fullwhen it is very cold.This allows for fluidexpansion if freezing occurs,which could damage thetank if it is completely full.

. Do not use engine coolant(antifreeze) in the windshieldwasher. It can damage thewindshield washer systemand paint.

BrakesThis vehicle has disc brakes.Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or beheard all the time the vehicle ismoving, except when applyingthe brake pedal firmly.

{ WARNING

The brake wear warning soundmeans that soon the brakes willnot work well. That could lead toa crash. When the brake wearwarning sound is heard, have thevehicle serviced.

Notice: Continuing to drive withworn-out brake pads could resultin costly brake repair.

Some driving conditions or climatescan cause a brake squeal whenthe brakes are first applied orlightly applied. This does not meansomething is wrong with the brakes.

Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts inthe proper sequence to torquespecifications in Capacities andSpecifications on page 12‑2.

Brake linings should always bereplaced as complete axle sets.

Brake Pedal Travel

See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be asign that brake service might berequired.

Brake Adjustment

Every time the brakes are applied,with or without the vehicle moving,the brakes adjust for wear.

Replacing Brake System Parts

The braking system on a vehicle iscomplex. Its many parts have to beof top quality and work well togetherif the vehicle is to have really goodbraking. The vehicle was designedand tested with top-quality brakeparts. When parts of the brakingsystem are replaced, be sure to getnew, approved replacement parts.If this is not done, the brakes mightnot work properly. For example,installing disc brake pads that arewrong for the vehicle, can changethe balance between the frontand rear brakes — for the worse.The braking performance expectedcan change in many other ways ifthe wrong replacement brake partsare installed.

Brake Fluid

The brake master cylinder reservoiris filled with DOT 3 brake fluidas indicated on the reservoir cap.See Engine Compartment Overviewon page 10‑6 for the location of thereservoir.

There are only two reasons whythe brake fluid level in the reservoirmight go down:. The brake fluid level goes down

because of normal brake liningwear. When new linings areinstalled, the fluid level goesback up.

. A fluid leak in the brakehydraulic system can also causea low fluid level. Have the brakehydraulic system fixed, since aleak means that sooner or laterthe brakes will not work well.

Do not top off the brake fluid.Adding fluid does not correct aleak. If fluid is added when thelinings are worn, there will be toomuch fluid when new brake liningsare installed. Add or remove brakefluid, as necessary, only when workis done on the brake hydraulicsystem.

{ WARNING

If too much brake fluid is added,it can spill on the engine andburn, if the engine is hot enough.You or others could be burned,and the vehicle could bedamaged. Add brake fluid onlywhen work is done on the brakehydraulic system.

When the brake fluid falls to a lowlevel, the brake warning light comeson. See Brake System WarningLight on page 5‑16.

What to Add

Use only new DOT 3 brakefluid from a sealed container.See Recommended Fluids andLubricants on page 11‑12.

Always clean the brake fluidreservoir cap and the areaaround the cap before removing it.This helps keep dirt from enteringthe reservoir.

{ WARNING

With the wrong kind of fluid inthe brake hydraulic system,the brakes might not work well.This could cause a crash. Alwaysuse the proper brake fluid.

Electrical System

FusesThe wiring circuits in the vehicleare protected from short circuitsby fuses. This greatly reducesthe chance of damage caused byelectrical problems.

Look at the silver-colored bandinside the fuse. If the band is brokenor melted, replace the fuse. Be sureto replace a bad fuse with a newone of the identical size and rating.

Replace a bad fuse with a new oneof the identical size and rating.

If there is a problem on the roadand a fuse needs to be replaced,the same amperage fuse can beborrowed. Choose some feature ofthe vehicle that is not needed to useand replace it as soon as possible.

There are two fuse blocks inthe vehicle: one in the enginecompartment and one in theinstrument panel.

There is a fuse puller located inthe engine compartment fuse block.See Engine Compartment FuseBlock on page 10‑40. It can be usedto easily remove fuses from the fuseblock.

Tire PressureTires need the correct amountof air pressure to operateeffectively.

Notice: Neither tireunderinflation noroverinflation is good.Underinflated tires, or tiresthat do not have enough air,can result in:. Tire overloading andoverheating which couldlead to a blowout.

. Premature orirregular wear.

. Poor handling.

. Reduced fuel economy.

Overinflated tires, or tiresthat have too much air, canresult in:. Unusual wear.. Poor handling.. Rough ride.. Needless damage fromroad hazards.

The Tire and LoadingInformation label on thevehicle indicates the originalequipment tires and the correctcold tire inflation pressures.The recommended pressureis the minimum air pressureneeded to support the vehicle'smaximum load carrying capacity.

For additional informationregarding how much weightthe vehicle can carry, and anexample of the Tire and LoadingInformation label, see VehicleLoad Limits on page 9‑18.How the vehicle is loadedaffects vehicle handling andride comfort. Never load thevehicle with more weight thanit was designed to carry.

When to Check

Check the tires once a monthor more. Do not forget thecompact spare tire, if the vehiclehas one. The cold compactspare should be at 420 kPa(60 psi). For additionalinformation regarding thecompact spare tire, seeCompact Spare Tire onpage 10‑75.

10-54 Vehicle Care

How to Check

Use a good quality pocket-typegauge to check tire pressure.Proper tire inflation cannot bedetermined by looking at the tire.Check the tire inflation pressurewhen the tires are cold, meaningthe vehicle has not been drivenfor at least three hours or nomore than 1.6 km (1 mi).

Remove the valve cap from thetire valve stem. Press the tiregauge firmly onto the valve toget a pressure measurement.If the cold tire inflation pressurematches the recommendedpressure on the Tire andLoading Information label, nofurther adjustment is necessary.If the inflation pressure is low,add air until the recommendedpressure is reached. If theinflation pressure is high, presson the metal stem in the centerof the tire valve to release air.

Re‐check the tire pressure withthe tire gauge.

Return the valve caps on thevalve stems to prevent leaksand keep out dirt and moisture.

Tire Pressure MonitorSystemThe Tire Pressure Monitor System(TPMS) uses radio and sensortechnology to check tire pressurelevels. The TPMS sensors monitorthe air pressure in your tires andtransmit tire pressure readings toa receiver located in the vehicle.

Each tire, including the spare(if provided), should be checkedmonthly when cold and inflated tothe inflation pressure recommendedby the vehicle manufacturer onthe vehicle placard or tire inflationpressure label. (If your vehicle hastires of a different size than the size

indicated on the vehicle placard ortire inflation pressure label, youshould determine the proper tireinflation pressure for those tires.)

As an added safety feature, yourvehicle has been equipped with atire pressure monitoring system(TPMS) that illuminates a lowtire pressure telltale when one ormore of your tires is significantlyunder‐inflated.

Accordingly, when the low tirepressure telltale illuminates, youshould stop and check your tires assoon as possible, and inflate themto the proper pressure. Driving ona significantly under‐inflated tirecauses the tire to overheat and canlead to tire failure. Under‐inflationalso reduces fuel efficiency andtire tread life, and may affect thevehicle's handling and stoppingability.

Vehicle Care 10-55

Please note that the TPMSis not a substitute for proper tiremaintenance, and it is the driver'sresponsibility to maintain correcttire pressure, even if under‐inflationhas not reached the level to triggerillumination of the TPMS low tirepressure telltale.

Your vehicle has also beenequipped with a TPMS malfunctionindicator to indicate when thesystem is not operating properly.The TPMS malfunction indicator iscombined with the low tire pressuretelltale. When the system detects amalfunction, the telltale will flash forapproximately one minute and thenremain continuously illuminated.This sequence will continue uponsubsequent vehicle start‐ups aslong as the malfunction exists.

When the malfunction indicatoris illuminated, the system may notbe able to detect or signal lowtire pressure as intended. TPMSmalfunctions may occur for a variety

of reasons, including the installationof replacement or alternate tires orwheels on the vehicle that preventthe TPMS from functioning properly.Always check the TPMS malfunctiontelltale after replacing one or moretires or wheels on your vehicle toensure that the replacement oralternate tires and wheels allowthe TPMS to continue to functionproperly.

Tire Pressure MonitorOperationThis vehicle may have a TirePressure Monitor System (TPMS).The TPMS is designed to warn thedriver when a low tire pressurecondition exists. TPMS sensors aremounted onto each tire and wheelassembly, excluding the spare tireand wheel assembly. The TPMSsensors monitor the air pressurein the tires and transmits the tirepressure readings to a receiverlocated in the vehicle.

When a low tire pressure conditionis detected, the TPMS illuminatesthe low tire pressure warning lightlocated on the instrument cluster.

If the warning light comes on,stop as soon as possible andinflate the tires to the recommendedpressure shown on the tire loadinginformation label. See Vehicle LoadLimits on page 9‑18.

A message to check the pressure ina specific tire displays in the DriverInformation Center (DIC). The lowtire pressure warning light and theDIC warning message come on ateach ignition cycle until the tiresare inflated to the correct inflationpressure. Using the DIC, tirepressure levels can be viewed.For additional information anddetails about the DIC operationand displays see Driver InformationCenter (DIC) on page 5‑23.

The low tire pressure warninglight may come on in cool weatherwhen the vehicle is first started, andthen turn off as the vehicle is driven.This could be an early indicator thatthe air pressure is getting low andneeds to be inflated to the properpressure.

A Tire and Loading Informationlabel shows the size of the originalequipment tires and the correctinflation pressure for the tires whenthey are cold. See Vehicle LoadLimits on page 9‑18, for an exampleof the Tire and Loading Informationlabel and its location. Also see TirePressure on page 10‑53.

The TPMS can warn abouta low tire pressure conditionbut it does not replace normaltire maintenance. See TireInspection on page 10‑59,Tire Rotation on page 10‑59and Tires on page 10‑46.

Notice: Tire sealant materials arenot all the same. A non-approvedtire sealant could damage theTPMS sensors. TPMS sensordamage caused by usingan incorrect tire sealant isnot covered by the vehiclewarranty. Always use onlythe GM-approved tire sealantavailable through your dealeror included in the vehicle.

TPMS Malfunction Light andMessage

The TPMS will not function properlyif one or more of the TPMS sensorsare missing or inoperable. Whenthe system detects a malfunction,the low tire pressure warning lightflashes for about one minute andthen stays on for the remainder ofthe ignition cycle. A DIC warningmessage also displays. The lowtire pressure warning light and DICwarning message come on at eachignition cycle until the problem iscorrected. Some of the conditionsthat can cause these to comeon are:. One of the road tires has been

replaced with the spare tire.The spare tire does not have aTPMS sensor. The malfunctionlight and DIC message shouldgo off after the road tire isreplaced and the sensormatching process is performedsuccessfully. See "TPMS SensorMatching Process" later in thissection.

. The TPMS sensor matchingprocess was not done ornot completed successfullyafter rotating the tires.The malfunction light andthe DIC message should gooff after successfully completingthe sensor matching process.See "TPMS Sensor MatchingProcess" later in this section

. One or more TPMS sensorsare missing or damaged.The DIC message and theTPMS malfunction light shouldgo off when the TPMS sensorsare installed and the sensormatching process is performedsuccessfully. See your dealerfor service.

. Replacement tires or wheels donot match the original equipmenttires or wheels. Tires and wheelsother than those recommendedcould prevent the TPMS fromfunctioning properly. See BuyingNew Tires on page 10‑61.

. Operating electronic devices orbeing near facilities using radiowave frequencies similar to theTPMS could cause the TPMSsensors to malfunction.

If the TPMS is not functioningproperly, it cannot detect or signal alow tire condition. See your dealerfor service if the TPMS malfunctionlight and DIC message comes onand stays on.

TPMS Sensor MatchingProcess

Each TPMS sensor has a uniqueidentification code. The identificationcode needs to be matched to a newtire/wheel position after rotating thetires or replacing one or more of theTPMS sensors. The TPMS sensormatching process should also beperformed after replacing a sparetire with a road tire containing theTPMS sensor. The malfunctionlight and the DIC message shouldgo off at the next ignition cycle.The sensors are matched to thetire/wheel positions, using a TPMSrelearn tool, in the following order:driver side front tire, passenger sidefront tire, passenger side rear tire,and driver side rear. See yourdealer for service or to purchasea relearn tool.

Tire InspectionWe recommend that the tires,including the spare tire, if thevehicle has one, be inspectedfor signs of wear or damage atleast once a month.

Replace the tire if:. The indicators at three or

more places around the tirecan be seen.

. There is cord or fabricshowing through the tire'srubber.

. The tread or sidewall iscracked, cut, or snaggeddeep enough to show cordor fabric.

. The tire has a bump, bulge,or split.

. The tire has a puncture, cut,or other damage that cannotbe repaired well because ofthe size or location of thedamage.

Tire RotationTires should be rotatedevery 12 000 km (7,500 mi).See Maintenance Schedule onpage 11‑3.

Tires are rotated to achievea uniform wear for all tires.The first rotation is the mostimportant.

Any time unusual wear isnoticed, rotate the tires assoon as possible and checkthe wheel alignment. Also checkfor damaged tires or wheels.See When It Is Time for NewTires on page 10‑60 and WheelReplacement on page 10‑65.

The rubber in tires ages over time.This also applies for the spare tire,if the vehicle has one, even if it isnever used. Multiple conditionsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place. Tires will typically needto be replaced due to wear beforethey may need to be replaceddue to age. Consult the tiremanufacturer for more informationon when tires should be replaced.

Vehicle Storage

Tires age when stored normallymounted on a parked vehicle.Park a vehicle that will be storedfor at least a month in a cool, dry,clean area away from direct sunlightto slow aging. This area should befree of grease, gasoline, or othersubstances that can deterioraterubber.

Parking for an extended periodcan cause flat spots on the tiresthat may result in vibrations whiledriving. When storing a vehicle forat least a month, remove the tiresor raise the vehicle to reduce theweight from the tires.

Buying New TiresGM has developed andmatched specific tires forthe vehicle. The originalequipment tires installed weredesigned to meet GeneralMotors Tire PerformanceCriteria Specification(TPC Spec) system rating.When replacement tiresare needed, GM stronglyrecommends buying tires withthe same TPC Spec rating.

GM's exclusive TPC Specsystem considers over adozen critical specifications thatimpact the overall performanceof the vehicle, including brakesystem performance, ride andhandling, traction control,and tire pressure monitoringperformance. GM's TPC Specnumber is molded onto the tire'ssidewall near the tire size. If thetires have an all‐season treaddesign, the TPC Spec numberwill be followed by MS for mudand snow. See Tire SidewallLabeling on page 10‑47 foradditional information.

GM recommends replacingall the tires at the same time.Uniform tread depth on alltires will help to maintainthe performance of thevehicle. Braking and handlingperformance may be adverselyaffected if all the tires are notreplaced at the same time. SeeTire Inspection on page 10‑59and Tire Rotation on page 10‑59for information on proper tirerotation.

{ WARNING

Tires could explode duringimproper service. Attemptingto mount or dismount a tirecould cause injury or death.Only your dealer or authorizedtire service center shouldmount or dismount the tires.

{ WARNING

Mixing tires of different sizes,brands, or types may causeloss of control of the vehicle,resulting in a crash or othervehicle damage. Use thecorrect size, brand, and typeof tires on all wheels.

{ WARNING

Using bias-ply tires on thevehicle may cause the wheelrim flanges to develop cracksafter many miles of driving.A tire and/or wheel could failsuddenly and cause a crash.Use only radial-ply tires withthe wheels on the vehicle.

If the vehicle tires must bereplaced with a tire that doesnot have a TPC Spec number,make sure they are the samesize, load range, speed rating,and construction (radial) as theoriginal tires.

Vehicles that have a tirepressure monitoring systemcould give an inaccuratelow‐pressure warning if non‐TPCSpec rated tires are installed.See Tire Pressure MonitorSystem on page 10‑54.

Different Size Tires andWheelsIf wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, tractioncontrol, and electronic stabilitycontrol, the performance of thesesystems can also be affected.

{ WARNING

If different sized wheels are used,there may not be an acceptablelevel of performance and safetyif tires not recommended forthose wheels are selected.This increases the chanceof a crash and serious injury.Only use GM specific wheeland tire systems developedfor the vehicle, and have themproperly installed by a GMcertified technician.

See Buying New Tires onpage 10‑61 and Accessoriesand Modifications on page 10‑3for additional information.

Uniform Tire QualityGradingQuality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width.For example:

Treadwear 200 Traction AATemperature A

The following information relatesto the system developed by theUnited States National HighwayTraffic Safety Administration(NHTSA), which grades tiresby treadwear, traction, andtemperature performance.This applies only to vehiclessold in the United States.

Page 346: 2012 GMC Terrain Owner Manual M - Owner Center Home GMC Terrain Owner Manual M Vehicle Care..... 10-1 General ... when you need to see a service manual for additional instructions

Black plate (64,1)GMC Terrain Owner Manual (Include Mex) - 2012

10-64 Vehicle Care

The grades are molded on thesidewalls of most passengercar tires. The Uniform TireQuality Grading (UTQG)system does not apply to deeptread, winter-type snow tires,space-saver, or temporary usespare tires, tires with nominalrim diameters of 10 to 12 inches(25 to 30 cm), or to somelimited-production tires.

While the tires available onGeneral Motors passengercars and light trucks may varywith respect to these grades,they must also conform tofederal safety requirements andadditional General Motors TirePerformance Criteria (TPC)standards.

All Passenger Car Tires MustConform to Federal SafetyRequirements In AdditionTo These Grades.

Treadwear

The treadwear grade is acomparative rating basedon the wear rate of the tirewhen tested under controlledconditions on a specifiedgovernment test course.For example, a tire graded150 would wear one and ahalf (1½) times as well onthe government course asa tire graded 100. The relativeperformance of tires dependsupon the actual conditions oftheir use, however, and maydepart significantly from thenorm due to variations indriving habits, service practicesand differences in roadcharacteristics and climate.

Traction – AA, A, B, C

The traction grades, fromhighest to lowest, are AA, A, B,and C. Those grades representthe tire's ability to stop onwet pavement as measuredunder controlled conditionson specified governmenttest surfaces of asphalt andconcrete. A tire marked C mayhave poor traction performance.Warning: The traction gradeassigned to this tire is basedon straight-ahead brakingtraction tests, and does notinclude acceleration, cornering,hydroplaning, or peak tractioncharacteristics.

Black plate (65,1)GMC Terrain Owner Manual (Include Mex) - 2012

Vehicle Care 10-65

Temperature – A, B, C

The temperature gradesare A (the highest), B, and C,representing the tire's resistanceto the generation of heat andits ability to dissipate heatwhen tested under controlledconditions on a specifiedindoor laboratory test wheel.Sustained high temperaturecan cause the material ofthe tire to degenerate andreduce tire life, and excessivetemperature can lead to suddentire failure. The grade Ccorresponds to a level ofperformance which allpassenger car tires must meetunder the Federal Motor SafetyStandard No. 109. Grades Band A represent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law. Warning: The

temperature grade for this tireis established for a tire thatis properly inflated and notoverloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heatbuildup and possible tire failure.

Wheel Alignment and TireBalanceThe tires and wheels werealigned and balanced at thefactory to provide the longest tirelife and best overall performance.Adjustments to wheel alignment andtire balancing will not be necessaryon a regular basis. However, checkthe alignment if there is unusual tirewear or if the vehicle is pulling toone side or the other. If the vehiclevibrates when driving on a smoothroad, the tires and wheels mightneed to be rebalanced. See yourdealer for proper diagnosis.

Wheel ReplacementReplace any wheel that is bent,cracked, or badly rusted orcorroded. If wheel nuts keep comingloose, the wheel, wheel bolts, andwheel nuts should be replaced.If the wheel leaks air, replace it.Some aluminum wheels can berepaired. See your dealer if anyof these conditions exist.

Your dealer will know the kind ofwheel that is needed.

Each new wheel should havethe same load-carrying capacity,diameter, width, offset, and bemounted the same way as theone it replaces.

If a Tire Goes FlatIt is unusual for a tire to blow outwhile driving, especially if the tiresare maintained properly. If air goesout of a tire, it is much more likely toleak out slowly. But if there ever is ablowout, here are a few tips aboutwhat to expect and what to do:

If a front tire fails, the flat tirecreates a drag that pulls the vehicletoward that side. Take your footoff the accelerator pedal and gripthe steering wheel firmly. Steer tomaintain lane position, and thengently brake to a stop, well off theroad, if possible.

A rear blowout, particularly on acurve, acts much like a skid andmay require the same correctionas used in a skid. Stop pressingthe accelerator pedal and steerto straighten the vehicle. It maybe very bumpy and noisy. Gentlybrake to a stop, well off the road,if possible.

{ WARNING

Driving on a flat tire will causepermanent damage to the tire.Re-inflating a tire after it hasbeen driven on while severelyunderinflated or flat may causea blowout and a serious crash.Never attempt to re-inflate a tirethat has been driven on whileseverely underinflated or flat.Have your dealer or an authorizedtire service center repair orreplace the flat tire as soonas possible.

{ WARNING

Lifting a vehicle and gettingunder it to do maintenance orrepairs is dangerous without theappropriate safety equipment andtraining. If a jack is provided withthe vehicle, it is designed only forchanging a flat tire. If it is used foranything else, you or others couldbe badly injured or killed if thevehicle slips off the jack. If a jackis provided with the vehicle, onlyuse it for changing a flat tire.

If a tire goes flat, avoid further tireand wheel damage by driving slowlyto a level place, well off the road,if possible. Turn on the hazardwarning flashers. See HazardWarning Flashers on page 6‑3.

Collision Damage Repair(U.S. and Canada)If the vehicle is involved in acollision and it is damaged,have the damage repaired by aqualified technician using the properequipment and quality replacementparts. Poorly performed collisionrepairs diminish the vehicle resalevalue, and safety performance canbe compromised in subsequentcollisions.

Collision Parts

Genuine GM Collision parts arenew parts made with the samematerials and construction methodsas the parts with which the vehiclewas originally built. Genuine GMCollision parts are the best choice toensure that the vehicle's designedappearance, durability, and safetyare preserved. The use of GenuineGM parts can help maintain the GMNew Vehicle Limited Warranty.

Recycled original equipmentparts may also be used for repair.These parts are typically removedfrom vehicles that were total lossesin prior crashes. In most cases,the parts being recycled are fromundamaged sections of the vehicle.A recycled original equipment GMpart may be an acceptable choiceto maintain the vehicle's originallydesigned appearance and safetyperformance; however, the historyof these parts is not known. Suchparts are not covered by the GMNew Vehicle Limited Warranty, andany related failures are not coveredby that warranty.

Aftermarket collision parts arealso available. These are made bycompanies other than GM and maynot have been tested for the vehicle.

As a result, these parts may fitpoorly, exhibit premature durability/corrosion problems, and may notperform properly in subsequentcollisions. Aftermarket parts are notcovered by the GM New VehicleLimited Warranty, and any vehiclefailure related to such parts is notcovered by that warranty.

Repair Facility

GM also recommends that youchoose a collision repair facility thatmeets your needs before you everneed collision repairs. Your dealermay have a collision repair centerwith GM-trained technicians andstate‐of‐the‐art equipment, or beable to recommend a collisionrepair center that has GM-trainedtechnicians and comparableequipment.

Insuring the Vehicle

Protect your investment in theGM vehicle with comprehensiveand collision insurance coverage.There are significant differencesin the quality of coverage affordedby various insurance policy terms.Many insurance policies providereduced protection to the GMvehicle by limiting compensationfor damage repairs by usingaftermarket collision parts.Some insurance companieswill not specify aftermarket collisionparts. When purchasing insurance,we recommend that you ensurethat the vehicle will be repairedwith GM original equipment collisionparts. If such insurance coverageis not available from your currentinsurance carrier, consider switchingto another insurance carrier.

If the vehicle is leased, the leasingcompany may require you to haveinsurance that ensures repairs withGenuine GM Original EquipmentManufacturer (OEM) parts orGenuine Manufacturer replacementparts. Read the lease carefully, asyou may be charged at the end ofthe lease for poor quality repairs.

If a Crash Occurs

If there has been an injury, callemergency services for help. Do notleave the scene of a crash until allmatters have been taken care of.Move the vehicle only if its positionputs you in danger, or you areinstructed to move it by a policeofficer.

Give only the necessary informationto police and other parties involvedin the crash.

For emergency towing seeRoadside Assistance Program(U.S. and Canada) on page 13‑8or Roadside Assistance Program(Mexico) on page 13‑10.

Gather the following information:. Driver name, address, and

telephone number.. Driver license number.. Owner name, address, and

telephone number.. Vehicle license plate number.. Vehicle make, model, and

model year.. Vehicle Identification

Number (VIN).. Insurance company and policy

number.. General description of the

Managing the Vehicle DamageRepair Process

In the event that the vehicle requiresdamage repairs, GM recommendsthat you take an active role in itsrepair. If you have a pre-determinedrepair facility of choice, take thevehicle there, or have it towedthere. Specify to the facility thatany required replacement collisionparts be original equipment parts,either new Genuine GM partsor recycled original GM parts.Remember, recycled parts willnot be covered by the GM vehiclewarranty.

Insurance pays the bill for the repair,but you must live with the repair.Depending on your policy limits,your insurance company mayinitially value the repair using

aftermarket parts. Discuss this withthe repair professional, and insiston Genuine GM parts. Remember,if the vehicle is leased, you maybe obligated to have the vehiclerepaired with Genuine GM parts,even if your insurance coveragedoes not pay the full cost.

If another party's insurancecompany is paying for the repairs,you are not obligated to accepta repair valuation based on thatinsurance company's collisionpolicy repair limits, as you haveno contractual limits with thatcompany. In such cases, you canhave control of the repair and partschoices as long as the cost stayswithin reasonable limits.

Vehicle DataRecording andPrivacyThis GM vehicle has a number ofsophisticated computers that recordinformation about the vehicle’sperformance and how it is driven.For example, the vehicle usescomputer modules to monitor andcontrol engine and transmissionperformance, to monitor theconditions for airbag deploymentand deploy airbags in a crash, and,if so equipped, to provide antilockbraking to help the driver control thevehicle. These modules may storedata to help your dealer technicianservice the vehicle. Some modulesmay also store data about how youoperate the vehicle, such as rate offuel consumption or average speed.These modules may also retain theowner’s personal preferences, suchas radio pre-sets, seat positions,and temperature settings.

Event Data RecordersThis vehicle has an Event DataRecorder (EDR). The main purposeof an EDR is to record, in certaincrash or near crash-like situations,such as an airbag deployment orhitting a road obstacle, data thatwill assist in understanding howa vehicle's systems performed.The EDR is designed to record datarelated to vehicle dynamics andsafety systems for a short period oftime, typically 30 seconds or less.The EDR in this vehicle is designedto record such data as:. How various systems in the

vehicle were operating.. Whether or not the driver and

passenger safety belts werebuckled/fastened.

. How far, if at all, the driver waspressing the accelerator and/orbrake pedal.

. How fast the vehicle wastraveling.

This data can help provide a betterunderstanding of the circumstancesin which crashes and injuries occur.

Important: EDR data is recordedby the vehicle only if a non-trivialcrash situation occurs; no data isrecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age,and crash location) is recorded.However, other parties, such aslaw enforcement, could combinethe EDR data with the type ofpersonally identifying dataroutinely acquired during acrash investigation.

To read data recorded by an EDR,special equipment is required, andaccess to the vehicle or the EDR isneeded. In addition to the vehiclemanufacturer, other parties, suchas law enforcement, that have thespecial equipment, can read theinformation if they have access tothe vehicle or the EDR.
