Active traction control system
(four−wheel drive models)
The active traction control system auto-
matically helps prevent the spinning of
4 wheels when the vehicle is started or
accelerated on slippery road surfaces.
D You may feel vibration or noise in your
vehicle, caused by operation of the
brakes. This indicates the system is
functioning properly.
When the engine switch is turned to “ON”,
the system automatically turns on.
The slip indicator light comes on for a few
seconds when the engine switch is turned
to “ON”. If the indicator light does not
come on when the engine switch is turned
on, contact your Toyota dealer.

The brake actuator temperature increases
during continuous operation of the active
traction control system, the vehicle stabil-
ity control system, the downhill assist con-
trol system and the hill−start assist control
system such as on slippery roads. If the
brake actuator temperature becomes too
high while any of the systems is operat-
ing, a buzzer will start to sound intermit-
tently to indicate that the active traction
control system can no longer operate. In
this case, immediately stop your vehicle at

maintained, even though the traction
control system is in operation. 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.
NORMAL DRIVING MODE

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.
If the system continues to operate, the
buzzer sound changes from intermittent to
continuous.
(The
continuous
buzzer
sounds for about 3 seconds.)
When the active traction control system is
operating, the following conditions occur:
