The brake pad or actuator temperature
increases during continuous operation of
the traction control system or vehicle sta-
bility control system such as on slippery
roads. If the brake pad or actuator tem-
perature becomes too high while the trac-
tion control system or vehicle stability
control system is operating, a buzzer will
start to sound intermittently to indicate
that the 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 “VSC TRAC” warning light
will come on and the traction control sys-
tem temporarily stops operating in order to
protect the brake pad. (Although the trac-
tion control system does not operate,
there is no problem to continue your driv-
ing.) The system will be automatically re-
stored after a short time and the warning
light goes out.
If the light comes on while driving, the
traction control system does not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving. In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
The “TRAC OFF” indicator light will come
on when the “VSC TRAC” warning light
comes on even if the “TRAC OFF” switch
is not pushed. The active traction control system auto-
matically helps prevent the spinning of
4 wheels (4WD mode) or rear wheels
(2WD mode) when the vehicle is started
or accelerated on slippery road sur-
faces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against 4 wheels (4WD mode)
or rear wheels (2WD mode) cannot be
maintained, even though the active
traction control system is in opera-
tion. Do not drive the vehicle under
any speed or maneuvering conditions
which may cause the vehicle to lose
traction control. In situations where
the road surface is covered with ice
or snow, your vehicle should be fitted
with snow tires or tire chains. Always
drive at an appropriate and cautious
speed for the present road condi-
tions.

Leave the system on during the ordi-
nary driving so that it can operate
when needed.
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 ac-
tive traction control system is in the self−
check mode, but does not indicate a mal-
function. When the active traction control system is
operating, the following conditions occur:
The system controls the spinning of the
4 wheels (4WD mode) or rear wheels
(2WD mode). At this time, the slip indi-
cator light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
The slip indicator light comes on for a few
seconds when the ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.u16029
“VSC TRAC” warning light
This light warns that there is a problem
somewhere in the active traction control
system or the vehicle stability control sys-
tem.
The warning light will come on when the
ignition key is turned to “ON” and will go
off after a few seconds.
