The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration.
1. SRS warning light
2. Front passenger occupant classification indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. Front passenger occupant classification system (ECU and sensors)
5. Front passenger ’s seat belt buckle switch
6. Side airbag modules (airbag and inflator)

7. Curtain shield airbag sensors
8. Side and curtain shield airbag sensors
9. Airbag sensor assembly
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly consists of a safing sensor and
airbag sensor.
In a severe side impact, the side and
curtain shield airbag sensor and/or the
curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain
shield airbag inflators. At this time, a
chemical reaction in the inflators quickly
fills the air bags with non −toxic gas to help
restrain the lateral motion of the occu-
pants.
In a vehicle rollover, the airbag sensor
assembly triggers the curtain shield airbag
inflator. At this time, a chemical reaction
in the inflators quickly fills the airbags
with non −toxic gas to help restrain the
lateral motion of front and second seat
occupants. When the airbags inflate, they produce a
fairly loud noise and release some smoke
and residue along with non
−toxic gas. This
does not indicate a fire. This smoke may
remain inside the vehicle for some time,
and may cause some minor irritation to
the eyes, skin or breathing. Be sure to
wash off any residue as soon as possible
to prevent any potential skin irritation with
soap and water. If you can safely exit
from the vehicle, you should do so imme-
diately.
Deployment of the airbags happens in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats as well as parts of the front
and rear pillar, front, center and rear gar-
nish and roof interior may be hot for sev-
eral minutes, but the airbags themselves
will not be hot. The airbags are designed
to inflate only once.CAUTION
SRS side airbags and curtain shield
airbags inflate with considerable
force. To reduce the possibility of
death or serious injury when they in-
flate, the driver, front passenger and
second seat passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.

The 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 side airbags and curtain
shield airbags are operating properly.This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system and
indicator light, front passenger ’s seat belt
buckle switch, seat belt pretensioner as-
semblies, inflators, roll sensing of curtain
shield airbags off indicator light, intercon-
necting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 132.)
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or starts flashing
while driving.
The SRS warning light will come on and
front passenger occupant classification in-
dicator light will indicate “OFF” if there is
a malfunction in the front passenger occu-
pant classification system.

When the ignition key is inserted and
turned on, the inside rear view mirror al-
ways turns on in the “AUTO” mode.
When the inside air temperature is low, it
may take a little longer for the mirror to
darken in response to the detection of
headlights.
CAUTION
Do not adjust the mirror while the
vehicle is moving. Doing so may
cause the driver to mishandle the ve-
hicle and an accident may occur re-
sulting in death or serious injuries.
13c570b
To ensure correct functioning of anti−glare
mirror sensors located on both sides of
the mirror, do not touch or cover the sen-
sors with your finger or a piece of cloth,
etc.

Pushing the “AUTO” button for longer
than 3 seconds turns on or off the
compass display.
The compass may not show the correct
direction in the following conditions:
The vehicle is stopped immediately af-
ter turning. The compass does not ad-
just while the vehicle is stopped.
The ignition switch is turned off imme-
diately after turning.
The vehicle is on an inclined surface.
The vehicle is in a place where the
earth’s magnetic field is subject to in-
terference by artificial magnetic fields
(underground parking, under a steel
tower, between buildings, roof parking,
near a crossing, near a large vehicle,
etc.).
The vehicle is magnetized. (There is a
magnet or a metal object on or near
the inside rear view mirror.)
The battery has been disconnected.
Any door is open.
If the deviation is small, the compass
works to calibrate the direction automati-
cally while the vehicle is in motion.
For obtaining additional precision or for
complete calibrating, see “Calibrating the
compass” below.
NOTICE
Do not put magnets or a metal object
near the inside rear view mirror. Do-
ing this may cause malfunction of the
compass sensor.
CALIBRATING THE COMPASS
(deviation calibration)
The direction display on the compass
deviates from the true direction deter-
mined by the earth’s magnetic field, The
amount of deviation varies according to
the geographic position of the vehicle.
To adjust for this deviation, stop the ve-
hicle and push the button for longer than
about 6 seconds until the number (1 −15)
appears on the display. Then push the
button again, referring to the following
map to select the number of the zone
where the vehicle is.

(b) Driver’s Seat Belt Reminder Lightand Buzzer
The light and buzzer act as a reminder to
buckle up the driver’s seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes and
the buzzer sounds if the driver ’s seat belt
is not fastened. Unless the driver fastens
the belt, the light continues flashing and
the buzzer sounds 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Re- minder Light
The light acts as a reminder to have the
front passenger buckle up the seat belt.
Once the ignition key is turned to “ON” or
“START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Unless
the front passenger fastens the belt, the
light continues flashing.
If luggage or other load is placed on the
front passenger seat, depending on its
weight and how it is placed on the seat,
built −in sensors in the seat cushion may
detect the pressure, causing the reminder
light to flash. (d) Charging System Warning Light
This warning light comes on when the
ignition key is turned to the “ON” position,
and goes off when the engine is started.
When there are problems in the charging
system while the engine is r
unning, the
warning light comes on.
NOTICE
When the charging system warning
light comes on while the engine is
running, malfunctions such as the en-
gine drive belt being broken may have
occurred. If the warning light comes
on, immediately stop the vehicle in a
safe place and contact your Toyota
dealer.
(e) Engine Oil Replacement Reminder Light
This light acts as a reminder to replace
the engine oil.
This light will come on when the ignition
switch is turned to “ON”, and will go off
after about a few seconds. When you drive for about 7200 km (4500
miles) after engine oil replacement, this
light illuminates for about 3 seconds and
then flashes for about 12 seconds with
the ignition key is turned to “ON” position.
If you continue driving without engine oil
replacement, and if the driving range ex-
ceeds 8000 km (5000 miles), the light will
come on after the ignition key is turned
to “ON” position. The light will remain on
thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road condition. If the light comes on, re-
place it as soon as possible.
You need to reset the light after the en-
gine oil replacement. Reset the light by
following the procedure below:
1. Turn the ignition key to the “LOCK” position
with the odometer reading
shown. (For details, see “Odometer and
trip meter” on page 131).
2. Turn the ignition key to the “ON” posi- tion while holding down the “ODO/
TRIP” knob.
Hold down the knob until the light goes
off. Before the light goes off, it illuminates
for 3 seconds, flashes for 2 seconds, illu-
minates for 1 second.

137
(h) SRS Warning Light
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 and seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system and
indicator light, front passenger ’s seat belt
buckle switch, seat belt pretensioner as-
semblies, inflators, roll sensing of curtain
shield airbags off indicator light, intercon-
necting wiring and power sources.
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion or remains on for more than 6
seconds or flashes.
The light comes on or flashes while
driving.The SRS warning light will come on and
front passenger occupant classification in-
dicator light will indicate “OFF” if there is
a malfunction in the front passenger occu-
pant classification system.
(i) “ABS” Warning Light
The light comes on when the ignition
key is turned to the “ON” position. If
the antilock brake system and the
brake assist system work properly, the
light turns off after a few seconds.
Thereafter, if either of the systems mal-
functions, the light comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti
−lock brake system, the brake assist
system, the vehicle stability control sys-
tem and/or active traction control system
do/does not operate, but the brake system
still operates conventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti −lock brake system does not operate
so that the wheels could lock up during
a sudden braking or braking on slippery
road surfaces. If either of the following conditions oc-
curs, this indicates a malfunction some-
where in the components monitored by
the warning light system. Contact your
Toyota dealer as soon as possible to
service the vehicle.
The light does not come on when the
ignition key is turned to the “ON” posi-
tion, or remains on.
The light comes on while you are driv-
ing.
A warning light turning on briefly during
operation does not indicate a problem.
CAUTION
If the “ABS” warning light remains on
together with the brake system warn-
ing light, immediately stop your ve-
hicle at a safe place and contact your
Toyota dealer.
In this case, not only the antilock
brake system will fail but also the
vehicle will become extremely unsta-
ble during braking.
