Driving
If the rear wheels spin, the slip
indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.
■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The AUTO LSD system will cease operation, and the slip indicator will
change from flashing to being on continuously to alert the driver. Stop the
vehicle in a safe place. (There is no problem with continuing normal driving.)
The system will be automatically restored after a short time.
When the AUTO LSD system is operating
CAUTION
■To avoid an accident
● Do not use the AUTO LSD system in conditions other than the above.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

2344-5. Using the driving support systems
If the vehicle gets stuck in fresh snow or mud, A-TRAC system 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.
Stop the vehicle completely,
and press the VSC off switch
for more than 3 seconds.
The “TRACTION CONTROL
OFF” will be shown on the dis-
play.
Press the switch again to turn
the system back on.
■When the “TRAC OFF” indicator light comes on or the message is dis-
played on the multi-information disp lay showing that “TRACTION CON-
TROL OFF” has been disabled even if the VSC off switch has not been
pressed
TRAC cannot be operated. Contact your Toyota dealer.
■ Sounds and vibrations caused by the ABS, brake assist, VSC, TRAC, A-
TRAC and Trailer Sway Control systems
● A sound may be heard from the engine compartment when the brake pedal
is depressed repeatedly, when the engine is started or just after the vehicle
begins to move. This sound does not indicate 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 after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ Reactivation of the TRAC/VSC/A-T RAC/Trailer Sway Control systems
Even after the TRAC/VSC/A-TRAC/Trailer Sway Control systems have been
turned off, turning the engine switch off and then on again will automatically
reactivate the TRAC/VSC/A-TRAC/Trailer Sway Control systems.
■ Reactivation of the TRAC system linked to vehicle speed
When only the TRAC system is turned off, the TRAC system will turn on
when vehicle speed increases. However, when both TRAC/VSC systems are
turned off, the systems will not turn on even when vehicle speed increases.

2364-5. Using the driving support systems
CAUTION
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC, A-TRAC, VSC and Trailer Sway Control systems will not
function correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension 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 Sway 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.
Failure 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 wheel.
● Begin releasing the accelerator pedal immediately but very gradually 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. 175)

2424-6. Driving tips
■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
● Install tire chains on the rear tires. Do not install tire chains on the front tires.
● Install tire chains on rear tires as tightly as possible. Retighten chains after
driving 1/4  1/2 mile (0.5  1.0 km).
● Install tire chains following the instructions provided with the tire chains.
CAUTION
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
● Use tires of the specified size.
● Maintain the recommended level of air pressure.
● Do not drive in excess of 75 mph (120 km/h), regardless of the type of
snow tires being used.
● Use snow tires on all, not just some wheels.
● 4WD models: Do not mix tires of different makes, models, tread patterns
or treadwear.
■ Driving with tire chains
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in the vehicle being unable to be driven safely,
and may cause death or serious injury.
● Do not drive in excess of the speed limit specified for the tire chains being
used, or 30 mph (50 km/h), whichever is lower.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

2464-6. Driving tips
■Additional information for off-road driving
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaini ng to driving your vehicle off-road,
consult the following organizations.
● State and Local Parks and Recreation Departments
● State Motor Vehicle Bureau
● Recreational Vehicle Clubs
● U.S. Forest Service and Bureau of Land Management
CAUTION
■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 spok es 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 driving 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. Th erefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is moving.
● When driving off-road or in rugged te rrain, 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.
