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 trac-
tion control system is in the self−check
mode, but does not indicate a malfunction.
When the traction control system is oper-
ating, the following conditions occur:
The system controls the spinning of the
D
rear wheels (two−wheel drive models)
or 4 wheels (four−wheel drive models).
At this time, the slip indicator light
blinks.
You may feel vibration or noise in your
D
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.

"VSC TRAC" warning light
This light warns that there is a problem
somewhere in the following.
Traction control system
D
Vehicle stability control system
D
"AUTO LSD" system
D
When the system is normal and the igni-
tion key is turned to "ON", the warning
light will come on and will go off after a
few seconds.
It is not a malfunction that the warning
light may stay on for 60 seconds after the
ignition key is turned to "ON".
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes out after a few seconds.
The brake actuator temperature increases
during continuous operation of the above
mentioned systems such as on slippery
roads. If the brake actuator temperature
becomes too high while any of the sys-
tems is operating, a buzzer will start to
sound intermittently to indicate that the
traction control system can no longer op-
erate. In this case, immediately stop your
vehicle at a safe place.
