Radial Tire
Two basic types of tire construction are bias-ply and radial. Thebias-ply tire has steel cord layers that run in the bias direction ina carcass. Radial tire has cords that run in the radial direction.The bias-ply tire is soft and provides a comfortable ride.However, the bias-ply tire generates higher temperature andbecomes less durable. Radial tires are made with strong beltscovering its circumference and are designed for high-speeddriving. Because of the higher rigidity of construction, they cor-ner better and have less rolling resistance. As a result, fuel econ-omy and tire durability are improved.

CD (Drag coefficient)
Flash surface Previous
CD is a coefficient to measure of air resistance that a vehiclereceives while it is moving. A vehicle with a lower CD numberwill have a smother design and greater aerodynamic efficiency.As a result, this contributes better fuel efficiency, vehicle accel-eration and high speed performance.
Resistances on a vehicle while driving
Even if two vehicles have the same front projection area, it ispossible to reduce air resistance of one vehicle by creating amore aerodynamic airflow. (Lesser CD coefficient)
The front projection area of new model is larger than the previ-ous model, however, because of its smooth body shape (includ-ing floor shape), body panel fit and reduced gaps, its air resist-ance is reduced. As a result, the aerodynamic performance andfuel efficiency is improved.
As a vehicle accelerates, air resistance becomes higher thanrolling resistance that are generated while driving.

Stepless Tilt AdjustableSteering Wheel
The tilt steering mechanism allows the driver to select a steer-ing wheel position (in the vertical direction) that is best suitablefor the driving posture.
The angle of the steering column can be adjusted by first press-ing down on the tilt lever as shown to “unlock” the tilt steer-ing mechanism. Once the steering wheel is adjusted to thedesired position, make sure to lock tilt mechanism by pullingup on the tilt lever.

This model uses a Theft Deterrent System (TDS) and an Immobilizer System.
Theft Deterrent System (TDS) is an alarm system thatsounds when a theft is detected. The alarm is activatedwhen any door is opened improperly.
Immobilizer is designed to disable the engine from startingunless the correct key is used to start the engine.
It compares the ID code of each ignition key and the ID coderegistered into the vehicle when the ignition key is inserted intothe key cylinder. If the codes do not match, the engine will notstart. ID code verification is confirmed, a security-warning lampwill turn OFF and enable the engine to start.
How to cancel the TDS1:Pressing the "Door Unlock" button of wireless transmitterkey will automatically cancel the TDS. If the door is unlockedby inserting the key (except for transmitter key) into the doorkey cylinder, the TDS will be activated. The key must then beinserted into the ignition key cylinder and turned to the ONposition to cancel the TDS.
Alarm condition will occur2: If the door is opened except the transmitter key operation,or the engine hood is opened by force.If the battery cables are removed once from the batteryand then re-connected.If the vehicle is subjected to an abnormal vibration orshock.
1: The TDS can be activated or cancelled by locking or unlocking the doors with thewireless transmitter key only.
2: When alarm is activated, the vehicle horn and security horn will sound (on/off),the interior light will illuminate and the hazard light will blink for 30 seconds.
This tip of each ignition key uses an electronic chip thatcontains an ID code. If the key is left in a high temper-ature area or subjected to static electricity, it may causepossible damage to the key and failure to start.
NOTE:
How to activate the TDS1:The TDS will automatically shifts to the armed state 30 sec-onds after the door is locked with the wireless transmitterkey.

D-4D 2nd Generation Common-rail
10
D-4D stands for Direct Injection 4-stroke Common-rail Diesel.It realizes high output power, low fuel consumption, less noiseand vibration, and low emissions by combining two systems:Direct Injection which features high output power and low fuelconsumption, and a Common-rail Diesel System which pro-vides high pressure, more precise and accurate fuel injectionthrough the use of computer control.
In a diesel engine, highly pressurized injected fuel mixes withcompressed, high temperature air in the combustion chamberand self-ignites causing combustion to occur. In Multi PilotInjection, a small amount of fuel is injected several times intothe combustion chamber to create small ignition. Then, main
In Direct Injection, an injection nozzle in the combustion cham-ber directly injects fuel to the the combustion chamber. It is veryeffective in high output, high efficiency, low fuel consumption,and reduction of PM (Particulate Matter) and CO2. (Althoughit requires a high-pressured injection system and more intakeair, its high efficiency is achieved through the use of Common-rail Diesel System and Turbocharger.)
[Reference]Sub-Combustion System: Fuel is injected into a sub chamber.After ignition occurs, the flame blows into the cylinder and cre-ates combustion. As compared with the Direct InjectionSystem, it becomes low output power.
Direct injection Indirect injection
injection is injected to complete combustion. As a result,engine output torque is increased and engine noise duringcombustion (diesel knock) is reduced. The Multi Pilot Injectionmethod is effective at low engine speeds and when cylindertemperature is low.
High-pressurized fuel created by new Higher Pressure SupplyPump is stored in a Common-rail, which is connected to theinjectors. Responding to a signal sent by the computer, theinjector opens, and high-pressurized fuel is injected into thecylinder. Compared to the previous diesel engine, theCommon-rail Diesel supplies high-pressurized fuel injectioneven at low engine speeds. As the highly pressurized fuel exitsthe injector’s very small holes (about the same diameter as ahuman hair), the fuel is sent to the combustion chamber as anextremely fine spray (particle of fuel is small). The fuel in mistform ensures that highly efficient fuel combustion is achieved.
In this model, improved output torque, low fuel consumptionand low emissions are realized by increasing fuel pressure. For fuel injection control (controlling the amount and timing offuel injection), a 32 Bit ECU (computer) with significantlyensured higher data processing speed is used.
Also, optimum injection control is carried out for each cylinderto reduce the fluctuation, enabling the difference between thecylinders. And with the pilot injection*, smooth rotation, lessnoise and vibration is realized.

VN Turbo (Variable Nozzle Vane TypeTurbocharger)
13
Intercooler
12
The Intercooler cools down the hot air, which is sent from theturbocharger to the engine. By lowering the temperature ofthe air, efficiency of the turbocharger and engine output powerare increased.
Turbochargers use exhaust gas energy to spin a turbine wheelwhich in turn spins an air pump. As this occurs, intake air iscompressed and forced into the engine by use of a similar tur-bine. Since the intake air is compressed, more air can enter theengine. As the amount of air entering the engine increases, theamount of fuel also increases. This increase in air and fuelresults in increased engine power.
VN turbo has a nozzle vane in the turbine housing. Accordingto the driver’s request which is calculated in ECU (computer),the VN controller changes the angle of nozzle by using an elec-tric motor.
At low engine speeds, exhaust pressure is low. Therefore, byclosing the nozzle vane creates acceleration in the exhaust gas,causing the turbine to spin faster, and increasing engine powerat low engine speed.
At high engine speeds, the exhaust gas pressure is high.Therefore, the nozzle vane is controlled to open.
VN turbo is effected at lower engine speed by applying theaccelerated exhaust gas to the turbine and it increases engineoutput power at low engine speed.
Intercooler is installed in an intake air duct and is locatedbetween the turbocharger and the engine. The air, that is com-pressed and heated by the turbocharger, is cooled down by thewind stream passing through the Intercooler. By reducing theintake air temperature, the air density* is increased and agreater amount of air is sent to the engine.

Oxygen is needed for fuel to combust. High airdensity enables more oxygen to be sent to theengine. When more oxygen is sent to theengine, the more fuel can be combusted. Thisleads to increased engine output power.
The intake air, cooled by Intercooler, has the same effect as increasing the engine displacement.
Balloons can change their size depending on the tempera-ture around them. Air expands when it is warmed up andcontracts when it is cooled down. In fact, when the air iscooled down, the volume of the air can be reduced with thesame amount of oxygen.

Fuel Cooler (exclusively for vehicleswith inter-cooler)
14
The high-pressured common-rail diesel engine uses a fuel cool-er to cool the fuel heated by the engine before returning it tothe tank. As the temperature of the fuel is lowered, the higherreliability of a fuel system is ensured.
The 1KD-FTV engine uses a pair of balance shafts as shown.They are designed to “balance” the vibrations and inertiaforces caused by combustion and rotating masses in theengine.
The engine produces power by converting the piston’s recipro-cating motion into rotary motion by using a crankshaft. The pis-ton’s reciprocating motion consists of four processes: intakeprocess (piston goes down), compression process (piston goesup), combustion process (piston goes down), and exhaustprocess (piston goes up). Therefore, in order for combustion tooccur in one cylinder, the piston needs to reciprocate twice.Among these four processes, combustion is the only processthat gives the piston a reciprocating force. As for the remainingthree processes, the piston continues its downwards/upwardsmovement by inertia produced during the combustion process.
As a result, imbalanced engine rotation can possibly causevibrations or engine noise during high engine speeds. The bal-ance shafts are driven by the crankshaft and rotate in oppositedirections to reduce vibrations caused by the combustionprocess and rotating engine mass, especially, for larger dis-placement engine.
Although the crankshaft and pistons inside the engine arelubricated with engine oil, Supply pump and injectors in adiesel engine are lubricated with the fuel itself.
To make high pressure, the Supply pump and injector of a com-mon-rail diesel are very elaborate. Their moving parts are lubri-cated with the oil ingredient contained in diesel fuel. If the tem-perature of diesel fuel becomes high, its viscosity is lowered. Asa result, the lubricating performance decreases and the protec-tive oil film on the part cannot be maintained.
In a Common-rail diesel system, some fuel that is compressedand sent from the supply pump is not injected but returned toa tank. High pressure and engine heating make the fuel tem-perature high. Because the characteristics of this engine createhigh pressure, the engine heating value becomes high, andcauses the return fuel temperature to increase. A fuel cooler isattached to the fuel return pipe to cool the return fuel andensure optimum lubricating performance.

4-valve Engine (Per cylinder)
16
This model uses an engine that has four valves per cylinder.There are two intake valves that allow fresh air to enter thecylinder in order to combust with the fuel and two exhaustvalves that allow the combusted gases to discharge from theengine.
By enlarging the total area of the intake and exhaust air pas-sages, more fresh air can be introduced into the engine andcombusted gases can be discharged more efficiently. Thus,overall combustion efficiency is improved. Also, componentssuch as valves and valve springs are lighter and can operate athigher engine speeds.

To help protect the environment, the amount of lead used hasbeen reduced and thorough development of lead-free partshas been implemented. The amount of lead used in one vehi-cle has decreased about 1/3 compared to a Hilux produced in1996.
This model uses lead free parts such as the radiator, heater core,fuel tank, wiring harness, black coating for window glass andwheel balance weights.

High rigidity body / High Tensile SteelSheets

A high Rigidity Body is a body whose structure is rigid againstbending and twisting.
Frame rigidity adds to the overall stability of the vehicle becausethe frame is the skeleton of the vehicle. In order to ensure high-er rigidity, the radial thickness and the cross-sectional height ofthe frame are optimized.Moreover, the higher rigidity of the cabin is also ensured byarranging High Tensile Steel Sheets* panel to a cabin optimally.
Coil springs are superior to leaf springs in absorbing shocks.Coil springs are lightweight and improve ride comfort.

Adaptation of Coil Spring
4WD models are ensured higher controllability and better ridecomfort by changing the attaching point of the stabilizer bar.Stabilizer bar is the spring that connect the right and left sus-pensions to counter a body roll*. The advantage of a stabilizerbar is that it reduces body roll without sacrificing riding com-fort.

Rack and Pinion Type Steering Gear Recirculating-ball Type Steering Gear
Steering GearHousing
This is a steering gear system. The rotation of the steeringwheel is transmitted to the steering pinion. It is then changedto lateral movement by a steering rack. The rack and pinion sys-tem changes tire angle as the steering wheel is turned.Compared to the recirculating-ball type steering system, it issimpler in structure, is lighter and stronger. The direct connec-tion between the pinion gear and the steering rack provides apositive and responsive steering feeling.
In response to the transfer lever shift position, ADD automati-cally connects or disconnects the power that is transmitted todrive the front wheels. When L4 or H4 mode is selected, ADDrealizes powerful driving in 4WD by transmitting power to thefront and rear wheels. However, when selecting H2 mode, thepower transmitted to the front wheels is disconnected. As aresult, economical driving is achieved.
If the power transmitted to the front wheels is not disconnect-ed when driving in 2WD, the drive train parts will rotate withthe front wheels, thus causing a large resistance.

ABS (Anti-lock Brake System)
23
Reverse Synchromesh
22
The synchromesh mechanism used for forward gears has beenadopted for reverse gear in order to realize a smooth shift feel-ing and prevent the grinding noise that occurs when shiftinginto reverse gear.
ABS is an abbreviation for Anti-lock Brake System.During sudden braking on a slippery road, ABS automaticallyprevents the wheels from locking up by using computer con-trol. Without ABS, if the wheels lock up, the driver can lose
steering control or braking distance can increase. ABS ensuresresponsive steering during the braking so that it may contributeto avoid an obstacle.
With ABS, the computer measures the rotationof each wheel when the brakes are applied,and automatically performs brake and releaseoperation repeatedly several times in a second.
To operate ABS effectively, it is necessary to apply as muchbrake pedal pressure as possible. When ABS is activated, thebrake pedal will vibrate or make a groaning noise. However,this condition is normal so it is necessary to continueto apply as much pedal pressure as possible.
ABS is designed to assist vehicle stability dur-ing braking, but not designed to shorten thebraking distance.
When the vehicle is moving backwards, the output shaftrotates in the opposite direction than that of a vehicle movingforward. Therefore, the idler gear needs to mesh the outputshaft and the counter shaft in order to change the direction ofrotation. At that time, if any shafts rotate, gear shifting intoreverse would not occur smoothly.
The manual transmission adopts a synchromesh mechanismthat equalizes rotation speeds between the shift gear and theshifted gear. For example, when shifting from 4th gear to 3rdgear, the rotating speed is different between both gears. Thetransmission would not shift smoothly and would make grind-ing noise without a synchomesh mechanism. The synchromeshmechanism synchronizes the speeds of both gears before shift-ing to provide a smooth shift feeling.
A reverse synchromesh mechanism stops the gears from rotat-ing to provide a smooth shift in reverse.
Synchromesh mechanism
The Right Way of Braking with ABS(Holding brake pedal firmly)
Each time the ignition switch is turned ON, a groaningsound can be heard as the vehicle is taking off. This isa normal condition that occurs when the ABS systemgoes through system self-check.
NOTE:
To avoid wheel locking on a vehicle with-out ABS, the driver must pump and releasethe brake pedal repeatedly, or apply thebrakes carefully before they lock. However, duringpanic braking, it is difficult for even the most experienced driv-er to pump and release the brake pedal. If the road is slippery,even more delicate braking is necessary.

LSPV (Load SensingProportioning Valve)
24
This system automatically regulates braking effectiveness of therear brakes in response to the changes in load (weight of pay-load) to provide optimal brake force distribution between thefront and rear brakes. As a result, braking performance is opti-mized for all load conditions (vehicle loaded or empty).
GOA is an abbreviation for “Global Outstanding Assessment”and is an evaluation for world-class safety.
This type of body structure minimizes deformations of thecabin in order to ensure cabin space in a collision. It is designedto absorb shocks and effectively distribute impact forcesthroughout the entire frame at the same time.
Cases of collision are examined many times through computersimulation analysis (CAE) and real vehicle tests such as full lapfront collision, offset front collision, and side collision. As aresult of our extensive testing in vehicle safety, our safety per-formance continues to be world top level in class.
Generally, the brake effectiveness of the rear brakes is less thanthe front brakes because of a small load acting on rear wheelswhen the vehicle is unloaded. Because of this small load, therear brakes tend to lock up easily when braking.
When the vehicle is loaded, a large load is acting on rearwheels, so they are less likely to lock up. Therefore, the amountof brake effectiveness on rear wheels can be increased in orderto shorten the braking distance.
A LSPV is fitted to the frame and connected to the rear axlehousing by a linkage. It is designed to detect any change in dis-tance between the frame and rear axle housing. LSPV regulatesthe rear brake hydraulic pressure as the vehicle height changes
from the changes in load. When the vehicle is loaded, thebrake pressure to the rear brakes is increased to optimize brakeforce distribution between the front and rear brakes.

Laminated Glass

This type of glass is used for the front windshield and is madeby combining two sheets of glass with one layer of transparentplastic (PVB or resin*) between them.Once bonded together, the glass “sandwich” behaves as a sin-gle unit and looks like normal glass.
Laminated glass is designed to resist penetration from impact.Even if its surface is damaged, this glass is designed to preventcracks from spreading and to keep glass fragments adhered tothe transparent layer for safety. In addition, the transparentfilm layer cuts ultra-violet rays 100%.

SLLC (Super Long-life Coolant)

Anti-corrosion Steel Sheets
28
The surface of a body is painted. This paint preserves theappearance and prevents rust at the same time. If the paint isscratched or peeled off, the steel plate will develop rust easily.Therefore, before a body is painted, it is pre-coated with zinc toraise the rust resistance capabilities.
Toyota Super Long-life Coolant is antifreeze that is used to coolthe engine. Its development is based on the previous Long-lifeCoolant. SLLC* is a formula of low phosphates and organicacids. This formula allows a longer service interval and delivershigher performance.
* SLLC is pink, LLC is red
Antifreeze works to suppress rust in an engine’s cooling system.Also in colder climate areas, it works to prevent the enginefrom freezing. However, as time passes, antifreeze deterioratesand it loses its corrosion inhibiting properties. Therefore, it isnecessary to service the cooling system at the recommendedservice interval.
[Reference]A zinc coating not only prevents direct air contact to the steelplate, but is also corrosive resistant itself. Zinc emits ions to pre-vent rust of a steel plate.

1. Commercially available LLC (Long-life Coolant) is notusually diluted. It must be diluted with water at thetime of use. However, SLLC does not need to bediluted because it is premixed (50%) with distilledwater. Also, please never mix tap water withantifreeze.
2. If SLLC is mixed with the other kinds of antifreeze,its service life will decrease.

Fuel Filter Warning System
30
It is necessary to supply clean fuel to the engine. This is veryimportant especially for a general Common-rail diesel enginesince it has many precision parts. Usually, fuel filter works toremove impurities and dirt from the fuel, and supply clean fuelto the engine. As a fuel filter accumulate impurities, its per-formance can fail. Therefore, the filter must be exchanged reg-ularly.
In contrast, the new Common-rail diesel engine has no regularmaintenance schedule of filter.The new Fuel Filtering System automatically turns on the warn-ing light in the combination meter to let the driver know whento replace the filter. This is done with the filter of high per-formance and capacity. A computer also monitors the fuel sys-tem for problems such as impurities and mixing of water.
Light ON: Any trouble detected in the filter system, or dirtof a filter.
Light blinking: Water is mixed in the fuel system (watermust be removed).

As for a Common-rail diesel engine of this model, theregular maintenance of a fuel filter is not necessaryany more. If any trouble is detected in the fuel system,a warning light will come on. When the light comes on,it is necessary to have it checked at the Toyota dealer.
