If the 4LO" (low speed four−wheel drive)
indicator light continues to blink and the
buzzer sounds when you operate the mul-
ti−mode control switch knob to the H4" or
L4" position, drive forward or backward in
a short distance, then stop the vehicle
completely, shift the automatic transmis-
sion selector lever securely into N" and
operate the switch knob again.
If the indicator continues to blink even if
doing so, contact your Toyota dealer as
soon as possible. There may be a trouble
in the four−wheel drive system.
CAUTION
Never operate the multi−mode control
switch knob if the wheels are slip-
ping. Stop the slipping or spinning
before operating.
The traction control system automatical-
ly helps prevent the spinning of rear
wheels when the vehicle is started or
accelerated on slippery road surfaces.
When the engine switch is turned to ON",
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power to the rear wheels cannot be
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
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 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
rear wheels. At this time, the slip indi-
cator light blinks.

(two−wheel drive models)

176
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 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 traction
control system, the AUTO LSD" system,
the vehicle stability control 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 oper-
ating, a buzzer will start to sound intermit-
tently to indicate that the traction control
system can no l onger 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 slip indicator light will
come on and the traction control system
temporarily stops operating in order to
protect the brake actuator. (Although the
traction 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 slip indi-
cator light goes out.
CY16075
TRACTION CONTROL OFF MODE
If your wheels get stuck in an ditch
when you are driving on a severe off
road and sand, turn off the traction
control system. This system that con-
trols engine performance interferes with
the process of freeing your wheels.
To turn off: Briefly push the VSC OFF"
switch.

When the system is normal and the en-
gine switch 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
engine switch 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.
If the VSC OFF" warning light flashes
while driving, the traction control system
does not work. However, as normal brak-
ing operates when being applied, there is
no problem to continue your driving.
In the following cases, contact your Toyota
dealer:

The AUTO LSD" system aids traction
by using the traction control system to
control engine performance and braking
when one of the rear wheels begins to
spin.
This system is used only when wheel
spinning occurs in a ditch or on a
rough surface.
This system is effective in case one of
the rear wheels is spinning.
NOTICE
Do not use the AUTO LSD" system
in conditions other than the above. A
much greater steering effort and more
careful cornering control will be re-
quired.
