ating, the following conditions occur:
The system controls the spinning of the
front 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

“VSC” 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.
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.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 skid control system helps
provide integrated control of the sys-
tems such as an antilock brake sys-
tem, brake assist system, traction con-
trol, engine control, etc. This system
automatically controls the output of the
brakes or engine to help prevent the
vehicle from skidding when cornering
on a slippery road surface or abrupt
steering wheel operation occurs.
This system activates when the vehicle
speed is about 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.)
If the vehicle is going to skid during driv-
ing, the slip indicator light blinks and an
alarm sounds intermittently. Special care
should be taken while driving.
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.“VSC” warning light

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 tire pressure warning system is de-
signed to provide warning when tire
pressure of any one of the tires is criti-
cally reduced while the vehicle is mov-
ing. The low tire pressure warning light
comes on to inform you that such low
tire pressure may hamper driving.
This system is not designed to operate
when the vehicle is stopped. Therefore,
check the tire pressures regularly. The
recommended cold tire pressures, tire size
and the vehicle capacity weight are on the
tire pressure label. (For instruction, see
“Checking tire pressure” in Section 72.)
Installed tires should be of the specified
size. They should be of the same size
and construction. If tires other than of the
specified size are used, or if tires of dif-
ferent sizes or constructions are mixed,
the tire pressure warning system will not
function properly.
LOW TIRE PRESSURE WARNING LIGHT
This light comes on when the ignition key
is turned to the “ON” position. It goes off
after a few seconds. This indicates that
the tire pressure warning system is func-
tioning properly.
If the low tire pressure warning light
comes on while driving, adjust tire
pressure to the specified level. (See
“Tires” in Section 8.)
After the tire pressure is adjusted, the
light should go off after driving at about
more than 30 km/h (19 mph) for some
time. If the light still remains, have the
tire pressure warning system checked at
your Toyota dealer.

not function properly under certain cir-
cumstances. In the following cases, the
low tire pressure warning light may not
come on even if the tire pressure is
low, or it may come on when the tire
pressure is actually normal.
The tread wear is uneven among the
installed tires.
A compact spare tire, snow tires, or
tire chains are used.
The tire pressure is excessively higher
than specified, or tire pressure is sud-
denly reduced due to bursts or other
causes.
The vehicle is driven on a slippery
road surface such as rough road and
frozen road.
The vehicle speed is less than 30 km/h
(19 mph) or more than 100 km/h (62

ing or rotating tires or wheels memo-
ries the present tire condition as a
standard.
After replacing or rotating the tires or
wheels, perform the initial adjustment as
follows.1. Park the vehicle at a safe place and apply the parking brake. Stop the en-
gine.

(19 mph) or over for about total 8
hours, when the tire pressure warning
system detects the normal tire pressur-
es.
Do not push the reset switch without ad-
justing the tire pressure to the specified
level. Otherwise, the low tire pressure
warning light may not come on even if the
tire pressure is low, or it may come on

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
Mast type antenna—To remove an anten-
na, carefully turn it counterclockwise.
NOTICE

Mast type antenna:
To prevent damage to the antenna,
make sure it is removed before
driving your Toyota through an au-
tomatic car wash.
 Onglass antenna (builtin on the
rear window glass):
Attaching the film (especially con-
ductive or metallic type) on the rear
glass will noticeably reduce the
sensitivity of the radio.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should face 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.
