SRS Airbag (Supplemental Restraint System Airbag)
70■SUBARU Advanced Frontal
Airbag SystemThis vehicle is equipped with a SUBARU
advanced frontal airbag system that
complies with the new advanced frontal
airbag requirements in the amended
Federal Motor Vehicle Safety Standard
(FMVSS) No. 208.
The SUBARU advanced frontal airbag
system automaticall y determines the
deployment force of the driver’s SRS
frontal airbag at the time of deployment as
well as whether or not to activate the front
passenger’s SRS frontal airbag and, if
activated, the deployment force of the
SRS frontal airbag at the time of deploy-
ment.
This vehicle has warning labels on the
driver’s and front passenger’s sun visors beginning with th
e phrase “EVEN WITH
ADVANCED AIR BAGS” and a tag
attached to the glove box lid beginning
with the phrase “Even with Advanced Air
Bags”. Make sure that you carefully read
the instructions on the warning labels and
tag.
Always wear your seatbelt. The SUBARU
advanced frontal airbag system is a
supplemental restraint system and must
be used in combination with a seatbelt. All
occupants should wear a seatbelt or be
seated in an appropriate child restraint
system.
For the locations of the SRS airbags, refer
to "Components" P68.
In a moderate to severe frontal collision,
the following components deploy.
 SRS frontal airbag for driver
 SRS frontal airbag for front passenger
 SRS curtain airbag*
 SRS knee airbag for driver
*: When an offset frontal collision that is
severe enough to deploy the front airbag
occurs.These components supplement the
seatbelts by reducing the impact to the
occupant’s head, chest and knees.
NOTEOnly driver’s SRS frontal airbag and
front passenger’s SRS frontal airbag
are controlled by the SUBARU
advanced frontal airbag system.
▼ Driver’s SRS frontal airbagThe driver’s SRS frontal airbag uses a
dual stage inflator. The inflator operates in
different ways depending on the severity
of impact.SRS airbag system warning light

72SRS airbag system warning lightIf the seatbelt buckle switch and/or front
passenger’s occupant detection system
have failed, the SRS airbag system
warning light will illuminate. Have the
system inspected by your SUBARU
dealer immediately if the SRS airbag
system warning light illuminates.
If your vehicle has sustained impact, this
may affect the proper function of the
SUBARU advanced frontal airbag system.
If the SRS airbag system warning light illu-
minates, immediately stop the vehicle in a
safe place, and consult a SUBARU
dealer.

Refer to "Front Passenger’s Frontal
Airbag ON and OFF Indicators" P135. ▼
Occupant detection system
1) Occupant detection sensorsThe occupant detection sensors are
installed between the seat and seat rails,
and monitor the physique and posture of
the front passenger. Using this informa-
tion, the occupant det ection system deter-
mines whether the front passenger’s SRS
frontal airbag should be deployed or not.

If the front passenger’s frontal airbag ON
and OFF indicators do not work properly,
do not allow anyone to sit on the front passenger’s seat and have the occupant

detection system checked by your
SUBARU dealer.
: Front passenger’s frontal airbag ON
indicator
: Front passenger’s frontal airbag
OFF indicator
Also, if luggage is placed on the front
passenger’s seat, this may adversely
affect the ability of the system to deter-
mine deployment. This may prevent the
front passenger’s frontal airbag ON and
OFF indicators from working properly.
Check that the indicators work properly.
When the OFF indicator turns off and the
ON indicator illuminates, the front
passenger’s frontal airbag may deploy
during a collision. Remove luggage from
the front passenger’s seat.
▼ Conditions in which front
passenger’s SRS frontal airbag is
not activatedThe front passenger’s SRS frontal airbag
will not be activated when any of the
following conditions are met regarding the
front passenger’s seat:
 The seat is empty.
 The seat is equipped with an appro-
priate child restrain t system and an infant
or a child is restrained in it. (See
WARNING that follows.)
 The front passenger’s occupant detec-
tion system is malfunctioning.
WARNING
Do not kick the front passenger seat
or subject it to severe impact. Oth-
erwise, the SRS airbag system
warning light may illuminate to indi-
cate a malfunction of the front pas-
senger occupant detection system.
In this case, immediately stop the
vehicle in a safe pl ace, and consult
a SUBARU dealer.

▽Examples of the types of acci -
dents in which the SRS side
airbag and SRS curtain airbag
are not designed to deploy in
most cases1) The vehicle is involved in frontal colli- sion with another vehicle (moving or stationary).
2) The vehicle is struck from behind.
3) The vehicle pitches end over end.
In the event of accidents like those illus-
trated, the SRS side airbag and SRS
curtain airbag are not designed to deploy
in most cases.1) First impact
2) Second impact
A) SRS curtain airbag
B) SRS side airbagIn an accident where the vehicle is struck
from the side more than once, the SRS
side airbag and SRS curtain airbag deploy
only once on the first impact.
Example: In the case of a double side
impact collision, first with one vehicle and
immediately followed by another from the same direction, once the SRS side airbag

and SRS curtain airbag are activated on
the first impact, they will not be activated
on the second.
■ SRS Airbag System MonitorsSRS airbag system warning lightA diagnostic system continually monitors
the readiness of the SRS airbag system
(including seatbelt pretensioners) with the
ignition switch in the “ON” position. The
SRS airbag system warn ing light will show
normal system operation by illuminating
for approximately 6 seconds when the
ignition switch is turned to the “ON” posi-
tion.
The following components are monitored
by the indicator:

properly in the event of a collision,
which may result in injury. Flashing or flickering of the
warning light No illumination of the warning
light when the ignition switch is
first turned to the “ON” position Continuous illumination of the
warning light Illumination of the warning light
while driving
WARNING
 When discarding an airbag
module or scrapping the entire
vehicle damaged by a collision,
consult your SUBARU dealer. The SRS airbag has no user-
serviceable parts. Do not use
electrical test equipment on any
circuit related to the SRS airbag
system. For required servicing of
the SRS airbag, consult your
