CY13019
The SRS (Supplemental Restraint Sys-
tem) front airbags are designed to pro-
vide further protection for the driver
and front passenger in addition to the
primary safety protection provided by
the seat belts.
Your vehicle is equipped with ADVANCED
AIRBAGS" designed based on US motor
vehicle safety standards (FMVSS208). The
airbag system controls airbag deployment
power for the driver and front passenger.
The driver airbag system consists of the
driver seat’s position sensor etc. The front
passenger ’s airbag system consists of the
front passenger occupant classification
sensor etc.

CY13280
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 8. 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 air bags 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. 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, primarily to the head and chest, it
may also cause other, less severe injuries
to the face, chest, arms and hands. These
are usually in the nature of minor burns
or abrasions and swelling, but the force of
a deploying airbag can cause more seri-
ous injuries, especially if an occupant’s
hands, arms, chest or head is in close
proximity to the airbag module at the time
of deployment. This is why it is important
for the occupant to: avoid placing any
object or part of the body between the
occupant and the airbag module; sit
straight and well back into the seat; wear
the available seat belt properly; and sit as
far as possible from the airbag module,
while still maintaining control of the ve-
hicle.
Parts of the airbag module (steering wheel
hub, airbag cover and inflator) may be hot
for several minutes after deployment, so
do not touch! The airbags inflate only
once. The windshield may be damaged by
absorbing some of the force of the inflat-
ing airbag.

The SRS side and curtain shield airbags
may deploy if a serious impact occurs
to the underside of your vehicle. Some
examples are shown in the illustration.
CY13278
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 air bags 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 air bags
with non−toxic gas to help restrain the
lateral motion of the occupants.

87
CY13294
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 95 in this Section.
CY13026
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.

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
14 in the table on page 93 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 14.
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.
CY13267a
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 engine switch is in the ON"
position with the condition 2 in the table
shown below.
Front passenger occupant
classification system

92
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:
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 rear/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 ON" indicator is illu-
minated when an adult is seated in the
front passenger seat. If the OFF" indica-
tor is illuminated, ask the passenger to sit
up straight, well back in the seat, and
with the seat belt worn correctly. If the
OFF" indicator still remains illuminated,
either ask the passenger to move to the
rear seat, or if that is not possible, move
the front passenger seat fully rearward. The front passenger occupant classifi-
cation indicator light will indicate ON"
and OFF" when the engine switch is
turned to the ON" position. After
about four seconds, it will go off. After
that, the front passenger occupant clas-
sification system operates and judges
whether to indicate ON" or OFF".
CY13299a
The SRS warning light will come on
and front passenger occupant classifi-
cation indicator light will indicate
OFF" if there is a malfunction in the
front passenger occupant classification
system.
