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
is started. This means that the traction
control system is in the selfcheck 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 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 front wheels.
To turn off: Push “TRAC OFF” switch.
The “TRAC OFF” indicator light will come
on.
To turn on: Push “TRAC OFF” switch
once again.
The “TRAC OFF” indicator light will go off.

The traction control system will automati-
cally go on, and the “TRAC OFF” indicator
light will go off when you drive over 30
km/h (19 mph) even if the “TRAC OFF”
switch is pushed to cancel the traction
control system.
“TRAC OFF” indicator light comes on for
a few seconds when the ignition key is
turned to “ON”. It will come on again
when you push the “TRAC OFF” switch to
turn off the system.
The light may come on for 60 seconds
after the ignition key is turned to the “ON”
position. It is normal if they go out after
a while.
Depressing the brake pedal repeatedly
may turn on the “TRAC OFF” indicator
light. It is normal if it goes out after a few
seconds.
In the following cases, contact your Toyota
dealer:
The indicator light does not come on
when the ignition key is turned “ON”.
The indicator light remains on after the
ignition is turned on.
The indicator light comes on with the
normal driving mode while driving.
“VSC TRAC” warning light
This light warns that there is a problem
somewhere in the traction control system
or the vehicle skid control system.
The light will come on when the ignition
key is turned to “ON”, and will go off after
about a few seconds.
The light may come on for 60 seconds
after the ignition key is turned to the “ON”
position. It is normal if they go out after
a while.
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 traction
control system or vehicle skid control sys-
tem such as on slippery roads. If the
brake actuator temperature becomes too
high while the traction control system or
vehicle skid control system is operating,
a buzzer will start to sound intermittently
to indicate that the traction control system
can no longer operate. In this case, imme-
diately 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 “VSC TRAC” warning light will come
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, there is
no problem to continue your driving.) The
system will be automatically restored after
a short time and the “VSC TRAC” warning
light goes out.
If the light comes on while driving, the
system does not work. However, as con-
ventional braking operates when applied,
there is no problem to continue your driv-
ing.

rear wheels (twowheel drive mode)
when the vehicle is started or acceler-
ated on slippery road surfaces.
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 to the 4 wheels (fourwheel
drive mode) or rear wheels (two
wheel drive mode) cannot be main-
tained, even though the traction con-
trol 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.
Leave the system on during the ordi-
nary driving so that it can operate
when needed.

ignition key is turned to “ON”.
The warning light comes on while driv-
ing. The vehicle skid control system helps
provide integrated control of the sys-
tems such as antilock brakes, traction
control, engine control, etc. This sys-
tem automatically controls the output of
the brakes or engine to help prevent
the vehicle from skidding when corner-
ing on a slippery road surface or oper-
ating steering wheel abruptly.
The vehicle skid control activates when
the vehicle speed is more than 15 km/h
(9 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the system is
in the selfcheck mode but does not indi-
cate a malfunction.
CAUTION
Do not rely excessively on the ve-
hicle skid control system. Even if
the vehicle skid control system is
operating, you must always drive
carefully and attentively to avoid
serious injury. Reckless driving will
result in an unexpected accident. If
the slip indicator light flashes,
sounding an alarm sounds, special
care should be taken while driving.
Only use tires of specified size. The
size, manufacture, 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 skid control sys-
tem may not function correctly.
When replacing the tires or wheels,
contact your Toyota dealer. (See
“Checking and replacing tires” in
Section 72.)

Type 3: AM·FM ETR radio/cassette player/
compact disc auto changer
This section describes some of the basic
features on Toyota audio systems. Some
information may not pertain to your sys-
tem.
Your audio system works when the ignition
key is in the “ACC” or “ON” position.
TURNING THE SYSTEM ON AND OFF
Push “PWR·VOL” or “PWR/VOL” to turn
the audio system on and off.
Push “AM”, “FM1·2”, “TAPE” or “CD” to
turn on that function without pushing
“PWR·VOL” or “PWR/VOL”.
You can turn on each player by inserting
a cassette tape or compact disc.
You can turn off each player by ejecting
the cassette tape or compact disc. If the
audio system was previously off, then the
entire audio system will be turned off
when you eject the cassette tape or com-
pact disc. If the another function was pre-
viously playing, it will come on again.
SWITCHING BETWEEN FUNCTIONS
Push “AM”, “FM1·2”, “TAPE” or “CD” if the
system is already on but you want to
switch from one function to another. TONE AND BALANCE
For details about your system’s tone and
balance controls, see the description of
your own system.
Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange, and bass levels. In
fact, different kinds of music and vocal
programs usually sound better with differ-
ent mixes of treble, midrange, and bass.
Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another.
