The SRS (Supplemental Restraint Sys-
tem) airbags are designed to provide
further protection for the driver and
front passenger in addition to the pri-
mary safety protection provided by the
seat belts.
In response to a severe frontal impact,
the SRS airbags work together with the
seat belts to help reduce injury by inflat-
ing. The SRS airbags help to reduce inju-
ries mainly to the driver’s or front passen-
ger ’s head or chest caused by directly
hitting the steering wheel or dashboard.
The front passenger airbag is activated
even with no passenger in the front seat.
Be sure to wear your seat belt properly.Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seat belt restraint
system by the driver and the front pas-
senger when the SRS airbags are inflated.
CAUTION
A driver or front passenger too close
to the steering wheel or dashboard
during airbag deployment can be
killed or seriously injured. Toyota
strongly recommends that:
The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
The front passenger sit as far back
as possible from the dashboard.
All vehicle occupants be properly
restrained using the available seat
belts.
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS airbags are operating
properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, front seat belt pretensioner assem-
blies, inflators, warning light, interconnect-
ing wiring and power sources. (For details,
see “Service reminder indicators and
warning buzzers” in Section 15.)

The SRS airbag system is designed to
activate in response to a severe frontal
impact within the shaded area between
the arrows in the illustration.
The SRS airbags will deploy if the severi-
ty of the impact is above the designed
threshold level, comparable to an approxi-
mate 25 km/h (15 mph) collision when
impacting straight into a fixed barrier that
does not move or deform.
If the severity of the impact is below the
above threshold level, the SRS airbags
may not deploy.However, this threshold velocity will be
considerably higher if the vehicle strikes
an object, such as a parked vehicle or
sign pole, which can move or deform on
impact, or if it is involved in an underride
collision (e.g. a collision in which the nose
of the vehicle “underrides”, or goes under,
the bed of a truck, etc.).
It is possible that in some collisions at the
lower zone of airbag sensor detection and
activation the SRS airbags and seat belt
pretensioners will not operate all together.
For the safety of all occupants, always
wear your seat belts properly.
Collision from the rear
Collision from the side
Vehicle rollover
The SRS airbags are not designed to
inflate if the vehicle is involved in a
side or rear collision, if it rolls over, or
if it is involved in a lowspeed frontal
collision.

NOTICE
Do not operate the back window wip-
er if the back window is dry. It may
scratch the glass.
To defog or defrost the back window,
push the switch with the back window
closed.
The key must be in the “ON” position.
The thin heater wires on the inside of the
back window will quickly clear the surface.
An indicator light will illuminate to indicate
the defogger is operating.
On some models, heater panels in the
outside rear view mirrors will also quickly
clear the surfaces.
Push the switch once again to turn the
defogger off.
The system will automatically shut off af-
ter the defoggers have operated about 15
minutes.Make sure you turn the defoggers off
when the surfaces are clear. Leaving the
defoggers on for a long time could cause
the battery to discharge, especially during
stopandgo driving. The defoggers are
not designed for drying rain water or for
melting snow.
CAUTION
On some models, since the mirror
surfaces can get hot, keep your
hands off them when the defogger
switch is on.
NOTICE
When cleaning the inside of the back
window, be careful not to scratch or
damage the heater wires or connec-
tors.

NOTICE
To ensure the correct audio system
operation:
Be careful not to spill beverages
over the audio system.
Do not put anything other than a
cassette tape or Compact Disc into
the slot.
The use of cellular phone inside or
near the vehicle may cause a noise
from the speakers of the audio sys-
tem which you are listening to.
However, this does not indicate a
malfunction.
RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radio—it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range. The farther you are
from a station, the weaker its signal will
be. In addition, reception conditions
change constantly as your vehicle moves.Here are some common reception prob-
lems that probably do not indicate a prob-
lem with your radio:
FM
Fading and drifting stations—Generally, the
effective range of FM is about 40 km (25
miles). Once outside this range, you may
notice fading and drifting, which increase
with the distance from the radio transmit-
ter. They are often accompanied by distor-
tion.
Multipath—FM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this
happens, the signals will cancel each oth-
er out, causing a momentary flutter or
loss of reception.
Static and fluttering—These occur when
signals are blocked by buildings, trees, or
other large objects. Increasing the bass
level may reduce static and fluttering.
Station swapping—If the FM signal you
are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the origi-
nal signal can be picked up again.AM
Fading—AM broadcasts are reflected by
the upper atmosphere—especially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound
alternately strong and weak.
Station interference—When a reflected sig-
nal and a signal received directly from a
radio station are very nearly the same
frequency, they can interfere with each
other, making it difficult to hear the broad-
cast.
Static—AM is easily affected by external
sources of electrical noise, such as high
tension power lines, lightening, or electri-
cal motors. This results in static.
CARING FOR YOUR CASSETTE PLAYER
AND TAPES
For the best performance for your cas-
sette player and tapes:
Clean the tape head and other parts regu-
larly.
A dirty tape head or tape path can
decrease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)

Use highquality cassettes.
Lowquality cassette tapes can cause
many problems, including poor sound,
inconsistent playing speed, and
constant autoreversing. They can also
get stuck or tangled in the cassette
player.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player
if you are not listening to it, especially
if it is hot outside.
Store cassettes in their cases and out
of direct sunlight.
Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side). The tape used in
these cassettes is thin and could get
stuck or tangled in the cassette player.
CARING FOR YOUR COMPACT DISC
PLAYER AND DISCS
Use only compact discs labeled as
shown. CDR (CDRecordable),
CDRW (CDRewritable) and personal
computer use CDROMs may not be
playable on your compact disc player.
Your compact disc player is intended
for use with 12 cm (4.7 in.) discs only.
Extremely high temperatures can keep
your compact disc player from working.
On hot days, use the air conditioning
to cool the vehicle interior before you
listen to a disc.
Bumpy roads or other vibrations may
make your compact disc player skip.
If moisture gets into your compact disc
player, you may not hear any sound
even though your compact disc player
appears to be working. Remove the
disc from the player and wait until it
dries.

Your compact disc player cannot play
special shaped or lowquality compact
discs such as those shown here. Do
not use them as the player could be
damaged.
Handle compact discs carefully, espe-
cially when you are inserting them.
Hold them on the edge and do not
bend them. Avoid getting fingerprints
on them, particularly on the shiny side.
Dirt, scrapes, warping, pin holes, or
other disc damage could cause the
player to skip or to repeat a section of
a track. (To see a pin hole, hold the
disc up to the light.)
Remove discs from the compact disc
player when you are not listening to
them. Store them in their plastic cases
away from moisture, heat, and direct
sunlight.
To clean a compact disc: Wipe it with a
soft, lintfree cloth that has been damp-
ened with water. Wipe in a straight line
from the center to the edge of the disc
(not in circles). Dry it with another soft,
lintfree cloth. Do not use a conventional
record cleaner or antistatic device.
CAUTION
Compact disc players use an invisible
laser beam which could cause hazard-
ous radiation exposure if directed
outside the unit. Be sure to operate
the player correctly.

Depressing the brake pedal on slippery
road surfaces such as on the manhole
cover, the steel plate under the construc-
tion, joints in the bridge, etc. on a rainy
day tends to activate the antilock brake
system.
You may hear a click or motor 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
antilock brake system is in the self
check mode, and does not indicate a mal-
function.
When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the antilock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the antilock brake sys-
tem activation, the brake pedal may
move a little forward.
CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tires grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at the moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The antilock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed
resulting in a longer stopping dis-
tance.
