Make sure the “AIRBAG ON” indica-
tor light is illuminated when using
the seat belt extender for the front
passenger seat. If the “AIRBAG
OFF” indicator light is illuminated,
disconnect the extender tongue
from the seat belt buckle, then re-
connect the seat belt. Reconnect
the seat belt extender after making
sure the “AIRBAG ON” indicator
light is illuminated. If you use the
seat belt extender while the “AIR-
BAG OFF” indicator is illuminated,
the front passenger airbag and side
airbag on the front passenger side
may not activate correctly, causing
death or serious injury in the event
of the collision.Be sure to wear the seat belt with-
out the seat belt extender if you
can fasten the seat belt without the
extender.
Do not use the seat belt extender
when installing a child restraint
system on the front or rear passen-
ger seat. If installing a child re-
straint system with the seat belt
extender connected to the seat belt,
the seat belt will not securely hold
the child restraint system, which
could cause death or serious injury
to the child or other passengers in
the event of collision.
13T013
To connect the extender to the seat
belt, insert the tab into the seat belt
buckle so that the “PRESS” signs on
the buckle release buttons of the ex-
tender and the seat belt are both facing
outward as shown.
You will hear a click when the tab locks
into the buckle.
When releasing the seat belt, press on
the buckle release button on the extender,
not on the seat belt. This helps prevent
damage to the vehicle interior and extend-
er itself.

The front passenger ’s seat belt pretension-
er will not activate if no passenger is
detected in the front passenger seat by
the front passenger occupant classification
system. However, the front passenger ’s
seat belt pretensioner may activate if lug-
gage is put on the seat, or the seat belt
is buckled up regardless of the presence
of an occupant in the seat. (As for the
front passenger occupant classification
system, see “—Front passenger occupant
classification system” on page 63.)
The seat belt pretensioners and SRS air-
bags may not operate together in all colli-
sions.
13T015
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. “AIRBAG ON” and “AIRBAG OFF” indi-
cator lights
4. Front passenger occupant classification
system (ECU and sensors)
5. Seat belt pretensioner assemblies
6. Front passenger ’s seat belt buckle
switch
7. 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 Scion dealer about any re-
pair and modification.

46
NOTICE
Do not perform any of the following
changes without consulting your
Scion dealer. Such changes can
interfere with proper operation of the
seat belt pretensioners in some
cases.

If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Scion dealer as soon as possible.
When the ignition key is turned to the
“ON” position, the light does not come
on or remains on for more than 6 sec-
onds.

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 ON” and “AIRBAG OFF” 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. Knee airbag module for driver
(airbag and inflator)
11. 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 inflat-
ors 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.

In the following cases, contact your Scion
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.

Collision from the rear
Collision from the front
Vehicle rollover
The SRS side airbags and curtain shield
airbags are not generally designed to
inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a low–speed side
collision.
13T030
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 ON” and “AIRBAG OFF” 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 consist 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.

Your vehicle is equipped with a front
passenger occupant classification sys-
tem. This system detects the conditions
1. through 4. in the table on page 65
and based on these conditions activates
or deactivates 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. through 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 seat seat-
back.
Put weight on the front passenger seat
by putting your hands or feet on the
seatback from the rear passenger seat.
13T081
The “AIRBAG ON” and “AIRBAG OFF”
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 OFF” indicator light will be
illuminated 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 “AIRBAG OFF” indicator light is
illuminated, one of the following is likely
to have occurred:
A rear passenger lifts the front passen-
ger seat cushion with his/her legs.
Objects are placed under the front pas-
senger seat.
The front passenger seatback is in
contact with the rear 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 ON” indicator
light is illuminated when an adult is
seated in the front passenger seat. If the
“AIRBAG OFF” indicator light is illumi-
nated, ask the passenger to sit up
straight, well back in the seat, and with
the seat belt worn correctly. If the “AIR-
BAG OFF” indicator light still remains illu-
minated, either ask the passenger to move
to the rear seat, or if that is not possible,
move the front passenger seat fully rear-
ward.

The “AIRBAG ON” and “AIRBAG OFF”
indicator lights will be illuminated ini-
tially when the ignition key is turned to
the “ON” position. After about four sec-
onds, they will go off. After that, the
front passenger occupant classification
system operates and judges which indi-
cator light be illuminated.

recognize him/her as a child depending on his/her physique and posture.
*2: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/her
as an adult depending on his/her physique or posture.
*3: Never install a rear−facing child restraint system on the front passenger seat. A forward−facing child restraint system should only
be installed on the front passenger seat when it is unavoidable. (See “Child restraint” on page 67 as for installing the child restraint
system.)
