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 seat belt pretensioners are
operating properly. This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front passenger occupant
classification system and indicator light,
front passenger ’s seat belt buckle switch,
seat belt pretensioner assemblies, inflat-
ors, warning light, “RSCA OFF” indicator
light, interconnecting wiring and power
sources. (For details, see “Service remind-
er indicators and warning buzzers” on
page 145 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.
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.
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. 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.

Collision from the rear
Collision from the side Vehicle rollover
The SRS front airbags are generally not
designed to inflate if the vehicle is in-
volved in a side or rear collision, if it
rolls over, or if it is involved in a low
speed frontal collision. But, when ever a
collision of any type causes sufficient
forward deceleration of the vehicle, de-
ployment of the SRS front airbags may
occur.
Hitting a curb, edge
of pavement or
hard surface Falling into or
jumping over
a deep hole
Landing hard or vehicle falling
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. Front passenger occupant classification indicator light
4. Airbag module for front passenger (airbag and inflator)
5. Front passenger occupant classification system (ECU and sensors)
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch

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 dashboard (shaded in the illustra-
tion) is scratched, cracked, or other-
wise 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. Front passenger occupant classification indicator light
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 sensors 8. 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.
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, front, center and rear
garnish and roof interior may be hot for
several minutes, but the airbags them-
selves will not be hot. The airbags are
designed to inflate only once.

Make sure the “RSCA OFF” indica-
tor light is off. The curtain shield
airbags will not inflate in a vehicle
rollover if this indicator light is on
and you may be killed or seriously
injured. For details, see “Roll sens-
ing of curtain shield airbags off
switch” on page 94 in this Section.
Do not allow anyone to get his/her
head closer to the area where the
side airbag and curtain shield air-
bag inflate, since these airbags
could inflate with considerable
speed and force. Otherwise, he/she
may be killed or seriously injured.
Special care should be taken espe-
cially when you have a small child
in the vehicle.Do not allow anyone to kneel on
the passenger seat, facing the pas-
senger ’s side door, since the side
airbag and curtain shield airbag
could inflate with considerable
speed and force. Otherwise, he/she
may be killed or seriously injured.
Special care should be taken espe-
cially when you have a small child
in the vehicle.

In the following cases, contact your Toyota
dealer as soon as possible:
Any of the SRS side airbags and cur-
tain shield airbags have been inflated.
The portion of the doors (shaded in the
illustration) was involved in an acci dent
that was not severe enough to cause
the SRS side airbags and curtain
shield airbags to inflate.
The surface of the seats with the side
airbag (shaded in the illustration) is
scratched, cracked, or otherwise dam-
aged.

NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
Your vehicle is equipped with a front
passenger occupant classification sys-
tem. This system detects the conditions
1—4 in the table on page 92 and based
on these conditions activates or deacti-
vates the following systems;
Front passenger airbag
Side airbag on the front passenger
seat
Front passenger ’s seat belt pretension-
er
The system monitors the weight and
load on the front passenger seat, and
the seat belt buckle switch to determine
conditions 1—4.
In order for the system to detect the
conditions correctly, do not do any of
the following:
Apply a heavy load to the front pas-
senger seat.
Attach a commercial seatback table,
etc. to the front passenger seatback.
Put weight on the front passenger seat
by putting your hands or feet on the
seatback from the rear passenger seat.
The front passenger occupant classifi-
cation indicator light indicates the ac-
tuation of the front passenger airbag,
side airbag on the front passenger seat
and front passenger ’s seat belt preten-
sioner.
The indicator light will indicate “OFF”
when the ignition switch is in the “ON”
position with the condition 2 in the table
shown below.
