The seat belt pretensioner system con-
sists mainly of the following components
and their locations are shown in the il-
lustration.1. Front airbag sensors
2. Seat belt pretensioner assemblies
3. Airbag sensor assembly
4. SRS warning light
The seat belt pretensioners are controlled
by the airbag sensor assembly. The airbag
sensor assembly consists of a safing sen-
sor and airbag sensor. When the seat belt pretensioners are acti-
vated, an operating noise may be heard
and a small amount of non
−toxic gas may
be released. This does not indicate that
a fire is occurring. This gas is normally
harmless.
Once the seat belt pretensioners have
been activated, the seat belt retractors
remain locked.
CAUTION
Do not modify, remove, strike or open
the seat belt pretensioner assemblies,
airbag sensor or surrounding area or
wiring. Failure to follow these instruc-
tions may prevent the seat belt pre-
tensioners from activating correctly,
cause sudden operation of the system
or disable the system, which could
result in death or serious injury. Con-
sult your Toyota dealer about any re-
pair and modification.
NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can
interfere with proper operation of the
seat belt pretensioners in some
cases.
 Installation of electronic devices
such as a mobile twoway radio,
cassette tape player or compact
disc player
 Repairs on or near the front seat
belt retractor assemblies
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end
 Repairs made on or near the front
fenders, front end structure or con-
sole

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 front seat belt pretensioners
are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side airbag sensors, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources. (For details, see
“Service reminder indicators and warning
buzzers” on page 88 in Section 1−6.) 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.
When the ignition key is turned to the
“ON” position, the light does not come
on, remains on or flashes.
The light comes on or starts flashing
while driving.
If any seat belt does not retract or can
not be pulled out due to a malfunction
or activation of the relevant seat belt
pretensioner.
The seat belt pretensioner assembly or
surrounding area has been damaged.In the following cases, contact your Toyota
dealer as soon as possible:
The front of the vehicle (shaded in the
illustration) was involved in an accident
that was not severe enough to cause
the seat belt pretensioners to operate.
Either seat belt pretensioner assembly
or surrounding area is scratched,
cracked, or otherwise damaged.

The SRS front airbags may also deploy
if a serious impact occurs to the under-
side of your vehicle. Some examples
are shown in the illustration.The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion. 1. Front airbag sensors
2. Airbag module for front passenger (airbag and inflator)
3. Driver ’s seat belt buckle switch
4. Driver ’s seat position sensor
5. Airbag sensor assembly
6. Airbag module for driver (airbag and inflator)
7. SRS warning light
The airbag sensor assembly consists of a
safing sensor and airbag sensor. The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors very quickly fills the airbags with
non−
toxic gas to help restrain the forward
motion of the occupants. The front airbags
then quickly deflate, so that there is no
obstruction of the driver ’s vision should it
be necessary to continue driving.
When the airbags inflate, they produce a
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.

Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover, dashboard
near the front passenger airbag,
front passenger airbag cover, front
passenger airbag or airbag sensor
assembly. Doing so may prevent the
front airbag system from activating
correctly, cause sudden activation
of the system or disable the sys-
tem, which could result in death or
serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.
If you wish to modify your vehicle for
the handicapped, consult with your
Toyota dealer. It may dangerously in-
terfere with the SRS front airbags op-
eration.NOTICE

This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This

sors, side airbag sensors, driver ’s seat
position sensor, driver ’s seat belt buckle
switch, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources. (For details, see

The SRS side airbag system may not
activate if the vehicle is subjected to a
collision from the side at certain
angles, or a collision to the side of the
vehicle body other than the passenger
compartment as shown in the illustra-
tion.
The SRS side airbags are designed to
inflate when the passenger compartment
area suffers a severe impact from the
side.
Always wear your seat belts properly.
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags are not designed
to inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a lowspeed side
collision.The SRS side airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion.1. SRS warning light
