Driving
■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.
■ If the brake system overheats
TRAC or A-TRAC 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.)
■ Shifting to “4L”
VSC and Trailer Sway Control are automatically turned off.

2384-5. Using the driving support systems
CAUTION
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may 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, especially in the
following situations:
● 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 potholes or uneven surfaces
■ TRAC or A-TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC or A-TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ When the VSC and Trailer Sway Control are activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC/A-TRAC/Trailer Sway Control systems are turned
off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to ensure vehicle stability and driving force,
do not turn the TRAC/VSC/A-TRAC/Trailer Sway Control systems off unless
necessary.

Driving
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)
