The brake actuator temperature increases
during the active traction control system
or vehicle stability control system operat-
ing. If the brake actuator temperature be-
comes too high while the active traction
control system or vehicle stability control
system is operating, a buzzer will start to
sound intermittently to indicate that the
active traction control system can no lon-
ger operate. In this case, immediately stop
your vehicle 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 active
traction control system temporarily stops
operating in order to protect the brake
actuator. (Although the active traction con-
trol system does not operate, there is no
problem to continue your driving.) The
system will be automatically restored after
a short time and “VSC/TRAC” warning
light goes off if the accelerator pedal is
released.
When the “ABS” warning light come on,
the active traction control system is not
operating.
The “VSC/TRAC” warning light will come
on when the ignition key is turned “ON”,
and will go off after a few seconds.The “VSC/TRAC” warning light may stay
on for 60 seconds after the ignition key
is turned to “ON” position. It is normal if
it goes off after a few seconds.
Depressing the brake pedal repeatedly
may turn on the “VSC/TRAC” warning
light. It is normal if it goes off after a few
seconds.
When the “VSC/TRAC” warning light
comes on the active traction control sys-
tem is not operating, but there is no prob-
lem if you continue to drive.
In the following cases, contact your Toyota
dealer:
The “VSC/TRAC” warning light does not
come on after the ignition key is turned
“ON”.
The “VSC/TRAC” remains on after the
ignition key is turned “ON”.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicles and
power to 4 wheels may not be main-
tained, even though the active trac-
tion control system is in operation.
Do not drive the vehicle under any
speed or maneuvering conditions
which will cause the vehicle to lose
traction. 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 road conditions pres-
ent.

NOTICE
Do not use liquid sealants for a flat
tire as tire pressure warning valve
and transmitter will be damaged.
When the tires must be repaired or
replaced, have them repaired or re-
placed by the nearest Toyota dealer
or an authorized tire dealer. The
tire pressure warning valves and
transmitters will be affected by the
installation or removal of tires.

IF THE TIRE PRESSURE WARNING
LIGHT BLINKS...
If the tire pressure warning light blinks
when the ignition switch is turned to
the “ON” position, the tire pressure
warning system is not working properly.
The system will be disabled in the follow-
ing conditions:
(When the condition becomes normal, the
system will work properly.)
If tires not equipped with tire pressure
warning valves and transmitters are
used.
If the ID code on the tire pressure
warning valves and transmitters is not
registered.
If electronic devices or facilities using
similar radio wave frequencies are
nearby.
If a radio set at similar frequencies is
in use in the vehicle.
If a window tint that affects the radio
wave signals is installed.
If the tire pressure warning select
switch is set to a different tire setting.
If there is a lot of snow or ice on the
vehicle, in particular around the wheels
or wheel housings.
If non −genuine Toyota wheels are used.
If tire chains are used.
If the spare tire is in a location subject
to poor radio wave signal reception.
If the tire inflation pressure is 500 kpa
(5.1 kgf/cm2 or bar, 73 psi) or more
higher than the specified level.
If the tire pressure warning light blinks
frequently when the ignition switch is
turned to the “ON” position, have it
checked by your Toyota dealer.
