NORMAL DRIVING MODE
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
rear wheels. At this time, the slip indi-
cator light blinks.
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 ignition key is turned
to “ON”. If the indicator light does not
come on when the ignition is turned on,
contact your Toyota dealer.
TRACTION CONTROL OFF MODE
If your wheels get stuck in a 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: Push “TRAC OFF” switch.
The “TRAC OFF” indicator light will come
on.
The vehicle stability control system is al-
ways activated, even if the traction control
system is turned off.
To turn on: Push “TRAC OFF” switch
once again.
The “TRAC OFF” indicator light will go off.

In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.
The “TRAC OFF” indicator light will come
on when the “VSC” warning light comes
on even if the “TRAC OFF” switch is not
pushed. The active traction control system auto-
matically helps prevent the spinning of
4 wheels (4WD mode) or rear wheels
(2WD mode) when the vehicle is started
or accelerated on slippery road sur-
faces.
When the ignition key is turned to “ON”,
the system automatically turns on.
CAUTION
Under certain slippery road condi-
tions, full traction of the vehicle and
power against 4 wheels (4WD mode)
or rear wheels (2WD mode) cannot be
maintained, even though the active
traction control system is in opera-
tion. 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.
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 ac-
tive traction control system is in the self
−
check mode, but does not indicate a mal-
function.

When the active traction control system is
operating, the following conditions occur:
The system controls the spinning of the
4 wheels (4WD mode) or rear wheels
(2WD mode). At this time, the slip indi-
cator light blinks.
You may feel vibration or noise in your
vehicle, caused by operation of the

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 active traction control
system or the vehicle stability control sys-
tem.
The warning light will come on when the
ignition key is turned to “ON” and will go
off after a few seconds. The brake pad or actuator temperature
increases during continuous operation of
the active traction control system or ve-
hicle stability control system such as on
slippery roads. If the brake pad or actua-
tor temperature becomes too high while
the active traction control system or ve-
hicle stability control system is operating,
a buzzer will start to sound intermittently
to indicate that the active traction control
system can no l
onger operate. In this
case, stop your vehicle immediately 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 con-
trol system temporarily stops operating in
order to protect the brake pad. (Although
the active traction control system does not
operate, there is no problem to continue
your driving.) The system will be automati-
cally restored after a short time and the
warning light goes out.
If the light comes on while driving, the
active traction control system does not
work. However, as conventional braking
operates when applied, there is no prob-
lem to continue your driving.

In the following cases, contact your Toyota
dealer:
The warning light does not come on
after the ignition key is turned to “ON”.
The warning light remains on after the
ignition key is turned to “ON”.
The warning light comes on while driv-
ing.The vehicle stability control system
helps provide integrated control of the
systems such as antilock brake sys-
tem, traction control, engine control,
etc. This system automatically controls
the brakes and engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
The vehicle stability control activates
when the vehicle speed is more than the
following speed.
Front drive control lever in “H”
15 km/h (9 mph)
Front drive control lever in “L4” 30 km/h (18 mph)
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 sys-
tem is in the self −check mode but does
not indicate a malfunction.
CAUTION
Do not rely excessively on the ve-
hicle stability control system. Even
if the vehicle stability control sys-
tem is operating, you must always
drive carefully and attentively to
avoid serious injury. Reckless driv-
ing will result in an unexpected ac-
cident. If the slip indicator light
blinks, sounding an alarm sounds,
special care should be taken while
driving.
Only use tires of specified size. The
size, manufacturer, brand and tread
pattern for all 4 tires should be the
same. If you use the tires other
than specified, or different type or
size, the vehicle stability control
system may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” on
page 377 in Section 72.)

The tandem master cylinder brake system
is a hydraulic system with two separate
sub−systems. If either sub −system s hould
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will increase. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power −assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserved
vacuum for one or two stops—but no
more!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTILOCK BRAKE SYSTEM
(with “ABS” warning light)
The antilock brake system is designed
to help prevent lockup of the wheels
during a sudden braking or braking on
slippery road surfaces. This assists in
providing directional stability and steer-
ing performance of the vehicle under
these circumstances.
Effective way to press the ABS brake
pedal: When the anti −lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti −lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. This
will result in reduced braking performan-
ce.
The anti −lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
