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. “AIR BAG ON” and “AIR BAG OFF” indicator 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 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 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.

58
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 part 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
rear outside passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
13T031
Do not allow anyone to lean against
the door when the vehicle is in use,
since the side airbag and curtain
shield airbag could inflate with con-
siderable speed and force. Other-
wise, he/she may be killed or seri-
ously injured. Special care should
be taken especially when you have
a small child in the vehicle.
Sit up straight and well back in the
seat, distributing your weight evenly
in the seat. Do not apply excessive
weight to the outer side of the
seats with a side airbag, and to the
front pillar, rear pillar and roof side
rail with a curtain shield airbag.

59
13T032
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.
13T033
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.
13T034
Do not allow anyone to get his/her
head or hands out of windows,
since the curtain shield 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.

60
13T079
Do not attach a cup holder or any
other device or object on or around
the door. When the side airbag in-
flates, the cup holder or any other
device or object will be thrown with
great force or the side airbag may
not activate correctly, resulting in
death or serious injury. Likewise,
the driver and front passenger
should not hold objects in their
arms or on their knees.
13T072
Do not attach a microphone or any
other device or object around the
area where the curtain shield airbag
activates such as on the windshield
glass, side door glass, front and
rear pillars, roof side rail and assist
grips. When the curtain shield air-
bag inflates, the microphone or oth-
er device or object will be thrown
away with great force or the curtain
shield airbag may not activate cor-
rectly, resulting in death or serious
injury.
Do not hook a hanger, heavy or
sharp pointed objects on the coat
hook. If the curtain shield airbag
inflates, those items will be thrown
away with great force or the curtain
shield airbag may not activate cor-
rectly, resulting in death or serious
injury. When you hang clothes,
hang them on the coat hook direct-
ly.
Do not use seat accessories which
cover the parts where the side air-
bags inflate. Such accessories may
prevent the side airbags from acti-
vating correctly, causing death or
serious injury.
Do not modify or replace the seats
or upholstery of the seats with side
airbags. Such changes may prevent
the side airbag system from activat-
ing correctly, disable the system or
cause the side airbags to inflate ac-
cidentally, resulting in death or seri-
ous injury.

61
Do not disassemble or repair the
front and rear pillars and roof side
rail containing the curtain shield
airbags. Such changes may disable
the system or cause the curtain
shield airbags to inflate accidental-
ly, resulting in death or serious in-
jury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Scion dealer about any
repair and modification.
If you wish to modify your vehicle for
a person with a physical disability,
consult your Scion dealer. It may dan-
gerously interfere with the SRS side
airbags and curtain shield airbags op-
eration.NOTICE
Do not perform any of the following
changes without consulting your
Scion dealer. Such changes can
interfere with proper operation of the
SRS side airbag and curtain shield
airbag system in some cases.
 Installation of electronic devices
such as a mobile two–way radio,
cassette tape player or compact
disc player
 Modification of the suspension sys-
tem
 Modification of the side structure of
the passenger compartment
 Repairs made on or near the con-
sole or front seat
13T080
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 SRS side airbags and curtain
shield airbags are operating properly.

62
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system,
“AIR BAG ON” indicator light, “AIR BAG
OFF” indicator light, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 105.)
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 light comes on while driving.
The SRS warning light and “AIR BAG
OFF” indicator light will come on if there
is a malfunction in the front passenger
occupant classification system.
13T037
In the following cases, contact your Scion
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 accident
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.
The portion of the front pillars, rear
pillars or roof side rail garnishes (pad-
ding) containing the curtain shield air-
bags inside (shaded in the illustration)
is scratched, cracked, or otherwise
damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Scion dealer.

63
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.
13T089
The “AIR BAG ON” and “AIR BAG 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 “AIR BAG 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 “AIR BAG 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 “AIR BAG ON” indica-
tor light is illuminated when an adult is
seated in the front passenger seat. If the
“AIR BAG 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.

classification system

64
The “AIR BAG ON” and “AIR BAG 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.
13T090
The SRS warning light and “AIR BAG
OFF” indicator light will come on if
there is a malfunction in the front pas-
senger occupant classification system.
