!SRS seat cushion airbag operation
1) Driver ’s side
2) Passenger ’s side
WARNING
The SRS seat cushion airbag is
designed not to deploy when the
seatbelt for the corresponding seat
is not fastened. For safety, all per-
sons in the vehicle should fasten
their seatbelts.
The SRS seat cushion airbags are de-
signed to deploy simultaneously when the
SRS frontal airbags deploy. For details
about the operating conditions, refer to
“SUBARU advanced frontal airbag opera-
tion ”F 1-57.
The front passenger ’s SRS seat cushion
airbag is designed not to deploy in either
of the following conditions.
. The front passenger ’s seatbelt is not
fastened (even when the front passen-
ger ’s frontal airbag ON indicator illumi-
nates while the OFF indicator remains off).
. The front passenger ’s frontal airbag
ON indicator is off while the OFF indicator
illuminates.
NOTE
When the front passenger ’s SRS fron-
tal airbag is deactivated by the occu-
pant detection system, the front pas-
senger ’s SRS seat cushion airbag is
also deactivated.
! SRS side airbag and SRS curtain
airbag operation
The following airbags deploy indepen-
dently of each other because each has
its own impact sensor.
.Driver ’s SRS side airbag
. Front passenger ’s SRS side airbag
. SRS curtain airbag (right-hand side)
. SRS curtain airbag (left-hand side)
Therefore, they may not both deploy in the
same accident. Also, the SRS side airbag
Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)

Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
deploys independently of the driver’s and
front passenger ’s SRS frontal airbags in
the steering wheel and instrument panel.
An impact sensor, which senses impact
force, is located in each of the following
locations.
. In the left and right front doors
. In the left and right center pillars
. In the left and right rear wheel houses
. In the airbag control module
. In the left and right front fenders (only
SRS curtain airbags are designed to
deploy when the front sub sensors sense
a severe impact.)
A rollover sensor is also located inside the
airbag control module.
If both of the following sensors together
sense an impact force above a predeter-
mined level in a side collision, the control
module causes both the SRS side airbag
and curtain airbag on the impacted side
to inflate regardless of whether the rear
wheel house impact sensor on the same
side senses an impact.
. the impact sensor that is located in the
airbag control module
. one of the center pillar impact sensors
or front door impact sensors
If both of the following sensors together sense an impact force above a predeter-
mined level in a side collision, the control
module causes
only the SRS curtain
airbag on the impacted side to inflate.
. the impact sensor that is located in the
airbag control module
. one of the rear wheel house impact
sensors
Even if a frontal collision occurs, both right
and left SRS curtain airbags will deploy
when the front sensor and the control unit
determine that the impact results from an
offset frontal collision.
The SRS curtain airbags are designed to
deploy under the following conditions.
. The driver ’s SRS frontal airbag deploys
or the driver ’s and passenger ’sSRS
frontal airbags deploy in a frontal collision.
. The system determines that the colli-
sion is an offset frontal collision.
. The vehicle is in an extremely inclined
state such as during a rollover.
The SRS curtain airbags are basically not
designed to deploy in the following cases.
. In a frontal collision when the SRS
frontal airbags do not deploy or the system
determines that the collision is other than
an offset frontal collision
. In most lesser inclined states If the rollover sensor detects rollover of the
vehicle, the control module inflates the
SRS curtain airbags
. At this time, the
driver ’s and front passenger ’s seatbelt
pretensioners also operate at the same
time.
After the deployment, the SRS side airbag
immediately starts to deflate. The time
required from detection of an impact to
deflation of an SRS side airbag after
deployment is shorter than the blink of
an eye.
The SRS curtain airbag remains inflated
for a while following deployment then
slowly deflates.
The SRS side airbag and SRS curtain
airbag deploy even when no one occupies
the seat on the side on which an impact is
applied.
The SRS side airbag and SRS curtain
airbag are designed as follows:
. to deploy in the event of an accident
involvingamoderatetosevereside
impact collision
. to function on a one-time-only basis.
The SRS side airbag and SRS curtain
airbag are not designed to deploy in the
following cases:
. in most lesser side impacts

WARNING
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system.
.Flashing or flickering of the warn-
ing 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
Immediatelytakeyourvehicleto
your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the seatbelt pretensioners and/or SRS
airbags will operate improperly (e.g.
SRS airbags may inflate in a very
minor collision or not inflate in a
severe collision), which may in-
crease the risk of injury.
&
SRS airbag system servicing
WARNING
. When discarding an airbag mod-
ule or scrapping the entire vehi-
cle damaged by a collision, con-
sult 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
nearest SUBARU dealer. Tamper-
ing with or disconnecting the
system ’s wiring could result in
accidental inflation of the SRS
airbag or could make the system
inoperative, which may result in
serious injury.
