The brake pad or actuator temperature
increases during continuous operation of
the active traction control system or ve-
hicle stability control system such as on
slippery roads. If the brake pad or actua-
tor temperature becomes too high while
the active traction control system or ve-
hicle stability control system is operating,
a buzzer will start to sound intermittently
to indicate that the active traction control
system can no longer operate. In this
case, stop your vehicle immediately at a
safe place.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous. (The continuous buzzer
sounds for about 3 seconds.)
At the time, the ªVSC TRACº warning light
will come on and the active traction con-
trol system temporarily stops operating in
order to protect the brake pad. (Although
the active traction control system does not
operate, there is no problem to continue
your driving.) The system will be automati-
cally restored after a short time and the
warning light goes out.
If the light comes on while driving, the
active traction control system does not
work. However, as conventional braking
operates when applied, there is no prob-
lem to continue your driving.In the following cases, contact your Toyota
dealer:

The warning light does not come on
after the ignition key is turned to ªONº.

The warning light remains on after the
ignition key is turned to ªONº.

The warning light comes on while driv-
ing.
The ªVSC OFFº indicator light will come
on when the ªVSC TRACº warning light
comes on even if the center differential
lock switch is not pushed.The vehicle stability control system
helps provide integrated control of the
systems such as anti±lock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
This vehicle stability control activates
when the vehicle speed is more than the
following speed.
Two±wheel drive models:
15 km/h (9 mph)
Four±wheel drive models:
ª2WDº or ª4HIº mode
15 km/h (9 mph)
ª4LOº mode 30 km/h (18 mph)
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
begins to move. This means that the sys-
tem is in the self±check mode but does
not indicate a malfunction.

CAUTION

Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks, sounding an alarm sounds,
special care should be taken while
driving.

Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
ªChecking and replacing tiresº on
page 432 in Section 7±2.)If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to ªONº. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.Four±wheel drive models onlyÐ
Pushing the center differential lock
switch automatically turns the vehicle
stability control system off. At this
time, the ªVSC OFFº indicator comes
on with the center differential lock indi-
cator light.
ªVSC OFFº indicator light comes on for a
few seconds when the ignition key is
turned to ªONº.

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 under-
body. 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 per-
son 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 mov-
ing.

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.
NOTICE

If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.

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 can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil's lubricating qualities.

Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.

Always perform a maintenance in-
spection after each day of off±road
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance informa-
tion, refer to the ªScheduled Main-
tenance Guideº or ªOwner's Manual
Supplementº.
