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.
In the following cases, contact your Toyota
dealer:
The indicator light does not come on
when the ignition key is turned “ON”.

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
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 sys-
tem 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 warning
light goes out.
If the light comes on while driving, the
traction control system does not work.
However, as conventional braking operates
when applied, there is no problem to con-
tinue your driving.

The warning light comes on while driv-
ing.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
is started. This means that the active
traction control system is in the self
check mode, but does not indicate a mal-
function.

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” to turn the audio system
on and off.
Push “AM”, “FM1·2”, “TAPE” or “CD” to
turn on that function without pushing
“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.YOUR RADIO ANTENNA
To lower a power antenna, turn off the
audio system by pushing “PWR·VOL” or
turn the ignition key to “LOCK”.
The power antenna automatically retracts
when the radio mode is switched off to
turn on the cassette tape player.
NOTICE

To prevent damage to the antenna,
make sure it is retracted before
driving your Toyota through an au-
tomatic car wash.
 On models with glass antenna, at-
taching film (especially conductive
or metallic type) on the rear glass
will noticeably reduce the sensitiv-
ity of the radio.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should be to the right.
NOTICE
Do not oil any part of the player and
do not insert anything other than cas-
sette tapes into the slot, or the tape
player may be damaged.
YOUR COMPACT DISC PLAYER
When you insert a disc, gently push it in
with the label side up. (The player will
automatically eject a disc if the label side
is down.) The compact disc player will
play from track 1 through the end of the
disc. Then it will play from track 1 again.
NOTICE
Never try to disassemble or oil any
part of the compact disc player. Do
not insert anything except a compact
disc into the slot.
The player is intended for use with 12 cm
(4.7 in.) discs only.
