XS13135a
This indicator comes on when the igni-
tion switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS airbags are operat-
ing properly.This warning light system monitors the
airbag sensor assembly, front airbag
sensors, side and curtain shield airbag
sensors, driver ’s seat position sensor,
driver ’s seat belt buckle switch, front
passenger occupant classification system
∗,
passenger airbag off switch, passenger
airbag on −off indicator light, seat belt
pretensioner assemblies, inflators, “RSCA
OFF” indicator light, interconnecting wiring
and power sources. (For details, see
“Service reminder indicators and warning
buzzers” on page 197 in Section 1 −6.)
∗: The front passenger occupant classifica-
tion system includes the front passenger
occupant classification ECU, load sensor
and front passenger ’s seat belt buckle
switch.
If either 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 switch is turned to the “ON”
position or remains on for more than
6 seconds.
The light comes on while driving. The SRS warning light will come on and
passenger airbag on
−off indicator light will
indicate “OFF” if there is a malfunction in
the front passenger occupant classification
system.

The SRS warning light and the passen-
ger airbag onoff indicator light will in-
dicate “OFF” if there is a malfunction
in the passenger airbag off switch.
CAUTION
Do not turn off the passenger air-
bag off switch except when a mem-
ber of a passenger risk group iden-
tified in TABLE 1 is occupying the
right front passenger seating posi-
tion.
When the passenger airbag off
switch is turned off, the front pas-
senger airbag will not inflate in a
collision and turning off the front
passenger airbag can reduce the
occupant protection which your ve-
hicle safety systems can provide to
you in certain accidents and in-
crease the likelihood of death or
serious personal injuries.
For details, see “—SRS driver airbag
and front passenger airbag” on page
75 in this Section.
XS13131
The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and right front passenger in addition to
the primary safety protection provided
by the seat belts.

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.
XS13104a
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. Passenger airbag on −off indicator light
3. Airbag module for front passenger (airbag and inflator)
4. Front passenger occupant classification ECU
5. Load sensor
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch 8. Driver ’s seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver (airbag and inflator)
11. SRS warning light
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The airbag sensors constantly monitor the
forward deceleration of the vehicle. If an
impact results in a forward deceleration
beyond the designed threshold level, the
system triggers the airbag inflators. At this
time a chemical reaction in the inflators
very quickly fills the airbags with non −tox-
ic gas to help restrain the forward motion
of the occupants. The front airbags then
quickly deflate, so that there is no ob-
struction 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.

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.

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. Passenger airbag on −off indicator light
3. Curtain shield airbag modules (airbag and inflator)
4. Front passenger occupant classification ECU
5. Load sensor
6. Side airbag modules (airbag and inflator) 7. Side and curtain shield airbag sensors
8. Front passenger ’s seat belt buckle
switch
9. Airbag sensor assembly
10. Curtain shield airbag sensors
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly.
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.
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 the 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 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.

The indicator light will indicate “OFF”
when the ignition switch is in the “ON”
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 “OFF” indicator is illuminated, one
of the following is likely to have occurred:
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the back wall.
To ensure that the system correctly de-
tects the presence or absence of a person
of adult size sitting in the right front pas-
senger seat, make sure that none of the
above occur.
Make sure that the “ON” indicator is illu-
minated when a person of adult size is
seated in the right front passenger seat.
If the “OFF” indicator is illuminated, follow
the procedure below: 1. Turn the ignition off.
2. Make sure the airbag off switch is set to the “AUTO” position.
3. Make sure the right front passenger seat belt is worn correctly. 4. Ask the front passenger to adjust the
seatback to the upright position and to
sit up straight on the center of the seat
cushion, with his/her legs comfortably
extended forward.
5. Turn the ignition on, having the pas- senger remain in that position until the
passenger airbag on −off indicator light
indicates “ON”.
If the “OFF” indicator remains illuminated,
move the right front passenger seat fully
rearward.

The SRS warning light will come on
and the passenger airbag onoff indica-
tor light will indicate “OFF” if there is
a malfunction in the front passenger
occupant classification system. Contact
your Toyota dealer as soon as possible.
