NORMAL DRIVING MODE
Leave the system on during ordinary
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 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 engine switch is turned
to the "ON" position. If the indicator light
does not come on when the engine switch
is turned on, contact your Toyota dealer.

The brake actuator temperature increases

ing systems under conditions such as on
slippery roads.

If the brake actuator temperature becomes
too high while any of the systems is oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no longer 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
sounds for about 3 seconds.)
At this time, the slip indicator light comes
on and the traction control system tempo-
rarily stops operating in order to protect
the brake actuator. (Although the traction
control system does not operate, it is not
a problem to continue driving.) The sys-
tem is automatically restored after a short
time and the slip indicator light goes off.

When getting the vehicle out of mud or
snow, etc., and only one of the rear
wheels begins to spin, it may be benefi-
cial to turn off the traction control sys-
tem. This system which also controls
engine performance may interfere with
the process of freeing the rear wheels.
