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. SRS warning light
3. Front passenger occupant classification
system (ECU and sensors)
4. Seat belt pretensioner assemblies
5. Front passenger 's seat belt buckle
switch
6. Airbag sensor assemblyThe 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 two- way 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

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. SRS warning light
3. Airbag module for front passenger
(airbag and inflator)
4. AIRBAG ONº and AIRBAG OFFº indi-
cator lights
5. Front passenger occupant classification
system (ECU and sensors)
6. Front passenger 's seat belt buckle
switch
7. Driver 's seat belt buckle switch8. Driver 's seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver
(airbag and inflator)
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.

If the light stays on, it indicates that the
SRS driver and front passenger airbag
system and/or front passenger occupant
classification system and AIRBAG ONº
and AIRBAG OFFº indicator lights have a
problem. If the light flashes, the SRS side
airbag system and/or curtain shield airbag
system have a problem.
The SRS warning light and AIRBAG OFFº
indicator light will come on if there is a
malfunction in the front passenger occu-
pant classification system.
In the following cases, contact your Toyota
dealer as soon as possible:
The SRS front airbags have been in-
flated.
The front of the vehicle (shaded in the

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. AIRBAG ONº and AIRBAG OFFº indi-
cator lights
3. Curtain shield airbag modules
(airbag and inflator)
4. Front passenger occupant classification
system (ECU and sensors)
5. Side airbag modules
(airbag and inflator)
6. Curtain shield airbag sensors
7. Side and curtain shield airbag sensors8. Front passenger 's seat belt buckle
switch
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 airbags with non- toxic gas to help
restrain the lateral motion of the occu-
pants.
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 designed 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 pillars, and roof side rail may be
hot for several 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 outside passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.

The AIRBAG ONº and AIRBAG OFFº
indicator lights indicate the actuation of
the front passenger airbag, side airbag
on the front passenger seat and front
passenger 's seat belt pretensioner.
The AIRBAG OFFº indicator light will be
illuminated when the ignition switch is in
the ONº position with the condition 2 in
the table shown below.If the front passenger occupant classifica-
tion system determines that a person of
adult size sits in the front passenger seat
but the AIRBAG OFFº indicator light is
illuminated, one of the following is likely
to have occurred:
A rear passenger lifts the front passen-
ger seat cushion with their legs.
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the second seat.
To ensure the system correctly detects an
adult sitting in the front passenger seat,
make sure the above do not occur.
Make sure that the AIRBAG ONº indicator
light is illuminated when an adult is
seated in the front passenger seat. If the
AIRBAG OFFº indicator light is illumina-
ted, ask the passenger to sit up straight,
well back in the seat, and with the seat
belt worn correctly. If the AIRBAG OFFº
indicator light still remains illuminated, ei-
ther ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward.The AIRBAG ONº and AIRBAG OFFº
indicator lights will be illuminated ini-
tially when the ignition key is turned to
the ONº position. After about 4 sec-
onds, they will go off. After that, the
front passenger occupant classification
system operates and judges which indi-
cator light be illuminated.
