Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, while the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control)
Maintains drive power and prevents the rear wheels (2WD models) or
four wheels (4WD models) from sp inning when starting the vehicle or
accelerating on slippery roads.
■ Hill-start assist control (if equipped)
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operates for approximately 5 seconds at
maximum.

When driving
When the VSC/TRAC/hill-start assist control systems are operating
If the vehicle is in danger of slip-
ping, the rear wheels (2WD mod-
els) or four wheels (4WD
models) spin, the vehicle starts
to roll backwards when starting
on an incline, this indicator
flashes to indicate that the VSC/
TRAC/hill-start assist control
systems have been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
The stop lights and high mounted
stoplight turn on when the hill-
start assist control system is
operating.
To disable TRAC and/or VSC
If the vehicle gets stuck in fresh snow or mud, TRAC and VSC may
reduce power from the engine to the wheels. You may need to turn
the system off to enable you to rock the vehicle in order to free it.
■Turning off TRAC (2WD models and 2WD mode on 4WD models)
Quickly push and release the
VSC OFF switch to turn off
TRAC.
The AUTO LSD indicator light
should come on.
Push the switch again to turn the
system back on.

194 2-4. Using other driving systems
■Turning off TRAC and VSC
Press and hold the VSC OFF
switch for more than 3 seconds
while the vehicle is stopped to
turn off both TRAC and VSC.
The VSC OFF indicator light
should come on.
Push the switch again to turn both
systems back on.
■Automatic reactivation of TRAC and VSC
Turning the engine switch off after turning off the TRAC and VSC systems
will automatically re-enable them.
■ Automatic TRAC reactivation (AUTO LSD mode)
With AUTO LSD mode, VSC OFF and AUTO LSD indicator lights turn on.
The TRAC system will turn on when the vehicle speed increases.
■ Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on
even when vehicle speed increases.
■ Sounds and vibrations caused by the ABS, TRAC, VSC, brake assist
and hill-start assist control system
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly when the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.

■Hill-start assist control is operational when (if equipped)
●The shift lever is in the D, 4, 3, 2 (5-speed automatic transmission), D, 3,
2 (4-speed automatic transmission) or L positions.
● The brake pedal is not depressed.
■ Hill-start assist control will not operate when (if equipped)
●The shift lever is in the P, R or N positions.
● The rear differential is locked.
■ If the brake system overheats
TRAC and hill-start control will cease operation and a buzzer will sound to
alert the driver. Stop the vehicle in a safe place. (There is no problem with
continuing normal driving.)

196 2-4. Using other driving systems
CAUTION
■The ABS does not operate effectively when
●The limits of the gripping performance have been exceeded.
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the ABS is operating will exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you in the following situ-
ations.
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with pothol es or roads with uneven roads
■ When VSC is activated
The slip indicator flashes and a warning buzzer sounds. Always drive care-
fully. Reckless driving may cause an accident. Exercise particular care when
the indicator flashes and a buzzer sounds.
■ TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ If the hill-start assist contro l does not operate effectively
Do not overly rely on the hill-start assist control. The hill start assist control
may not operate effectively on steep inclines and roads covered in ice.
■ Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and total
load capacity. In addition, make sure that the tires are inflated to the appro-
priate tire pressure level.
The ABS and VSC will not function correctly if different tires are fitted on the
vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.

Off-road precautions (4WD models and PreRunner)
Off-road vehicle feature
● Specific design characteristics give it a higher center of gravity
than ordinary passenger cars. This vehicle design feature causes
this type of vehicle to be more likely to rollover. And, it has a signif-
icantly higher rollover rate than other types of vehicles.
● An advantage of the higher ground clearance is a better view of the
road allowing you to anticipate problems.
● It is not designed for cornering at the same speeds as ordinary
passenger cars any more than low-slung sports cars are designed
to perform satisfactorily under of f-road conditions. Therefore, sharp
turns at excessive speeds may cause rollover.
This vehicle has higher ground cl earance and narrower tread in rela-
tion to the height of its center of gravity to make it capable of per-
forming in a wide variety of off-road applications.

Off-road vehicle precautions
Always observe the following precautions to minimize the risk of serious per-
sonal injury or damage to your vehicle:
●In a rollover crash, an unbelted person is significantly more likely to die
than a person wearing a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is moving.
● Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or
vehicle rollover causing death or serious injury.
● Avoid loading any items on the roof that will raise the vehicle’s center of
gravity.
● Always slow down in gusty crosswi nds. Because of its profile and higher
center of gravity, your vehicle is more sensitive to side winds than an ordi-
nary passenger car. Slowing down will allow you to have much better con-
trol.
● When driving off-road or in rugged terrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may cause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chassis.
● Do not drive horizontally across steep slopes. Driving straight up or
straight down is preferred. Your vehicle (or any similar off-road vehicle)
can tip over sideways much more easily than forward or backward.

200 2-5. Driving information
Off-road drivingWhen driving your vehicle off-road, please observe the following pre-
cautions to ensure your driving enjoyment and to help prevent the
closure of areas to off-road vehicles.
● Drive your vehicle only in areas wh ere off-road vehicles are permit-
ted to travel.
● Respect private property. Get owner’s permission before entering
private property.
● Do not enter areas that are closed. Honor gates, barriers and signs
that restrict travel.
● Stay on established roads. When conditions are wet, driving tech-
niques should be changed or trav el delayed to prevent damage to
roads.
