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
illustration) was involved in an accident
that was not severe enough to cause
the SRS front airbags to inflate.

The pad section of the steering wheel
or front passenger airbag cover
(shaded in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.

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.
