Do not put any kind of cover or clothes or other
objects over either front seatback and do not
attach labels or stickers to the front seat sur-
face on or near the SRS side airbag. They could
prevent proper deployment of the SRS side air-
bag, reducing protection available to the front
seat

and chest.
C) After deployment, SRS side airbag starts to deflate im- mediately.
The SRS side airbag can function only when the igni-
tion switch is in the “ON” position.
The driver’s and front passenger’s SRS side airbags
deploy independently of each other since each has its
own impact sensor. Also, the SRS side airbag deploys
independently of the frontal airbags in the steering
wheel and instrument panel.
An impact sensor is incorporated into each of the ve-
hicle’s center pillars. If either sensor detects a certain
predetermined amount of force during a side impact
collision, the control module sends a signal to the side
airbag module on the impacted side of the vehicle, in-
structing it to inflate the SRS side airbag. Then the
side airbag module produces gas, which instantly in-
flates the SRS side airbag. After the deployment, the
SRS side airbag immediately starts to deflate. The
time required from detecting impact to the deflation of
the SRS side airbag after deployment is shorter than
the blink of an eye.
The SRS side airbag deploys even when no one occu-
pies the seat on the side on which an impact is ap-
plied. When the SRS side airbag deploys, a sudden, fairly
loud inflation noise will be heard and some smoke will
be released. These occurrences are normal result of
the deployment. This smoke does not indicate a fire in
the vehicle.
Do not touch the SRS side airbag system com-
ponents around the
front seatback with bare
hands right after deployment. Doing so can
cause burns because the components can be
very hot as a result of deployment.
The SRS side airbag is designed to deploy in the event
of an accident involving a moderate to severe side im-
pact collision. It is basically not designed to deploy in
lesser side impact. Also, it is basically not designed to
deploy in frontal or rear impacts because SRS side air-
bag deployment would not help the occupant in those
situations.
Each SRS side airbag is designed to function on a
one-time-only basis.
SRS side airbag deployment depends on the level of
force experienced in the passenger compartment dur-
ing a side impact collision. That level differs from one

type of collision to another, and it may have no bearing
on the visible damage done to the vehicle itself. When will the SRS side airbag most likely de-
ploy?
A severe side impact near the front seat activates the
SRS side airbag.

1) The vehicle is involved in an ob- lique side-on impact.
2) The vehicle is involved in a side-on impact in an area outside the vicin-
ity of the passenger compartment.
3) The vehicle strikes a telephone pole or similar object.
4) The vehicle is involved in a side-on impact from a motorcycle.
5) The vehicle rolls onto its side or
roof.

There are many types of collisions which might not
necessarily require SRS side airbag deployment. In
the event of accidents like those illustrated, the SRS
side airbag may not deploy depending on the level of
accident forces involved.
When will the SRS side airbag not deploy?
1) The vehicle is involved in frontal collision with another vehicle (moving or stationary).
2) The vehicle is struck from behind.

The SRS side airbag is basically not designed to de-
ploy if the vehicle is involved in a frontal collision or is
struck from behind. Examples of such accidents are il-
lustrated.
1) First impact
2) Second impact
In an accident where the vehicle is struck from the side
more than once, the SRS side airbag deploys only
once.
Example: In the case of a double side impact collision,
first with one vehicle and immediately followed by an-
other from the same direction, once the SRS side air-
bag is activated on the first impact, it will not be activated on the second.
SRS airbag system monitors
A diagnostic system continually monitors the readi-
ness of the SRS airbag system while the vehicle is be-
ing driven. The SRS airbag system warning light
“AIRBAG” will show normal system operation by light-
ing for about 6 seconds when the ignition key is turned
to the “ON” position.
The following components are monitored by the indi- cator: Front sub sensor (Right hand side)
Front sub sensor (Left hand side)

All related wiring
In the event of a malfunction indicated by any of follow-
ing, the vehicle should be taken promptly to your near-
est SUBARU dealer to have the system checked.
Unless checked and repaired, the SRS airbags will not
function reliably: Flashing or flickering of the indicator 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.
SRS airbag system servicing
When discarding an airbag module or scrap- ping the entire car 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, see
your nearest SUBARU dealer. Tampering with
or disconnecting the system
