WARNING
■Shifting the front-wheel drive control switch from “2WD” to “4H ” while
driving
Never operate the front-wheel drive control switch if the wheel s are slipping.
Stop the slipping or spinning before shifting.
■ When the vehicle is parked
If the shift lever is moved before the “4LO” indicator turns on/off, the transfer
mode may not be shifted completely. The transfer mode disengage s both
the front and rear driveshafts from the powertrain and allows the vehicle to
move regardless of the shift position. (At this time, the indicator blinks and
the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic tr ansmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode before placing transmission in P. ( P. 298)
NOTICE
■To prevent damage to the center differential
● For normal driving on dry and hard surface roads, unlock the center differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
loose or bumpy surface.
● Do not push the center differential lock switch when the vehicle is corner-
ing or when its wheels are spinning freely off the ground.

the “TRAC OFF” indicator will come on. Stop the vehicle in a safe place.
(There is no problem with continuing normal driving.) The syste m will be auto-
matically restored after a short time.
WARNING
■ To avoid an accident
Failure to do so, a much greater steering effort and more careful cornering
control will be required.
● Do not use the AUTO LSD system in conditions other than when on e of
the drive wheels spinning occurs in a ditch or rough surface.
● Do not drive with the AUTO LSD system continuously turned on.
NOTICE
■Activating while driving
Do not activate the AUTO LSD system if the wheel is slipping. S top the slip-
ping or spinning before activating.

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenl y,
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 p edal
is depressed when the system de tects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or
turning on slippery road surfaces
◆Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing driving torque when
trailer sway is detected.
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from
spinning when starting the vehicl e or accelerating on slippery roads
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when start -
ing on an uphill
To keep driving safety and perf ormance, the following systems
operate automatically in respon se to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heav ily when operating the vehi-
cle.

reduce power from the engi ne to the wheels. Pressing
to turn the
system off may make it easier for you to rock the vehicle in or der to
free it.
2WD models and 2WD mode on 4WD models
To turn the TRAC system off,
quickly press and release

WARNING
■When the TRAC/VSC/Trailer Sway Control systems is turned off
Be especially careful and drive at a speed appropriate to the r oad condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC/Trailer Sway Control systems off unless
necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, trea d pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC, Trailer Sway Control and VSC systems will not function
correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replaci ng tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspensio n will affect
the driving assist systems, and may cause a system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Swa y Control sys-
tem may not be effective. Refer to your trailer owner’s manual for informa-
tion on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
● Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering w heel.
● Begin releasing the accelerator pedal immediately but very grad ually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( P. 193)

WARNING
■Off-road driving precautions
Always observe the following precautions to minimize the risk of death, seri-
ous injury or damage to your vehicle:
● Drive carefully when off the road. Do not take unnecessary risks by driving
in dangerous places.
● Do not grip the steering wheel spokes when driving off-road. A bad bump
could jerk the wheel and injure your hands. Keep both hands and espe-
cially your thumbs on the outside of the rim.
● Always check your brakes for effectiveness immediately after dr iving in
sand, mud, water or snow.
● After driving through tall grass, mud, rock, sand, rivers, etc. , check that
there is no grass, bush, paper, rags, stone, sand, etc. adhering or trapped
on the underbody. Clear off any such matter from the underbody. If the
vehicle is used with these materials trapped or adhering to the underbody,
a breakdown or fire could occur.
● In a rollover crash, an unbelted person is significantly more likely to die
than a person wearing a seat belt. Therefore, the driver and al l passengers
should fasten their seat belts whenever the vehicle is moving.
● 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 chass is.

NOTICE
■To prevent water damage
● Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams , first check
the depth of the water and the bottom of the riverbed for firmn ess. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand and mud that has accumulated in brake drums and around bra ke
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-r oad driv-
ing that has taken you through rough terrain, sand, mud, or wat er. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.
