The airbag control module causes both
the SRS side airbag andSRS curtain
airbag on the impacted side to inflate if
both of the following sensors together
sense an impact force above a predeter-
mined level in a side collision.
. One of the center pillar impact sensors
. Impact sensor that is located under the
rear center seat
The airbag control module causes only the
SRS curtain airbag on the impacted side
to inflate if both of the following sensors
together sense an impact force above a
predetermined level in a side collision.
. One of the rear wheel house impact
sensors
. Impact sensor that is located under the
rear center seat
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 to deploy in the event
of an accident involving a moderate to
severe side impact collision. They are
basically not designed to deploy in a
lesser side impact. Also, they are basically
not designed to deploy in frontal or rear
impacts because SRS side airbag and
SRS curtain airbag deployment would not
help the occupant in those situations.
Each SRS side airbag and SRS curtain
airbag are designed to function on a one-
time-only basis.
SRS side airbag and SRS curtain airbag
deployment depend on the level of force
experienced in the passenger compart-
ment during 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.
!
Example of the type of accident in
which the SRS side airbag and SRS
curtain airbag will most likely de-
ploy.
A severe side impact near the front seat
activates the SRS side airbag and SRS
curtain airbag.

Seat, seatbelt and SRS airbags
! Examples of the types of accidents in which the SRS side airbag and SRS
curtain airbag are unlikely to deploy.
1) The vehicle is involved in an oblique
side-on impact.
2) The vehicle is involved in a side-on impact in an area outside the vicinity 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 and SRS curtain airbag deploy-
ment. In the event of accidents like those
illustrated, the SRS side airbag and SRS
curtain airbag may not deploy depending
on the level of accident forces involved.

! Examples of the types of accidents
in which the SRS side airbag and
SRS curtain airbag will basically not
deploy.1) The vehicle is involved in frontal collision
with another vehicle (moving or station-
ary). 2) The vehicle is struck from behind.
The SRS side airbag and SRS curtain
airbag are basically not designed to
deploy if the vehicle is involved in a frontal
collision or is struck from behind. Exam-
ples of such accidents are illustrated.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 front seatbelt pretensioners)
while the vehicle is being driven. The
SRS airbag system warning light “AIR-
BAG ”will show normal system operation
by lighting for approximately 6 seconds
when the ignition switch is turned to the
“ON ”position.

be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system. Immediately take your vehi-
cle to your nearest SUBARU dealer
to have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbag will not operate properly in
the event of a collision, which may
increase 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.
CAUTION
If you need service or repair in areas
indicated in the following list, have
the work performed by an author-
ized SUBARU dealer. The SRS air-

nents of the SRS airbag system are
replaced, use only genuine SUBARU
parts.
NOTEIn the following cases, contact your
SUBARU dealer as soon as possible.

involved in an accident in which only
the driver ’s SRS frontal airbag or both
driver ’s and front passenger ’sSRS
frontal airbags did not deploy.

cover over the front passenger ’s SRS
frontal airbag, or either roof side (from
the front pillar to a point over the rear
seat) is scratched, cracked, or other-
wise damaged.
. Center pillar, rear wheel house or
rear sub frame, or an area near these
parts, was involved in an accident in
which the SRS side airbag and SRS
curtain airbag did not deploy.
. The fabric or leather of either front
seatback is cut, frayed, or otherwise
damaged.
. The rear part of the vehicle was
involved in an accident in which no
SRS airbag was deployed.
& Precautions against vehicle

parking facility.
CAUTION
Do not attach a large key holder or
key case to either key. If it bangs
against your knees while you are
driving, it could turn the ignition
switch from the “ON ”position to the
“ Acc ”or “LOCK ”position, thereby
stopping the engine.& Key number plateThe key number is stamped on the key
number plate attached to the key set.
Write down the key number and keep it in
another safe place, not in the vehicle. This
number is needed to make a replacement

Immobilizer
CAUTION
FCC WARNING
Changes or modifications not ex-
pressly approved by the party re-
sponsible for compliance could void
the user ’s authority to operate the
equipment.
The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle’ s immobilizer system can
be used to operate your vehicle. Even if
an unregistered key fits into the ignition
switch and can be turned to the “START ”
position, the engine will automatically stop
after several seconds.
Each immobilizer key contains a trans-
ponder in which the key ’s ID code is
stored. When a key is inserted into the
ignition switch and turned to the “ON”
position, the transponder transmits the
key ’s ID code to the immobilizer system ’s
receiver. If the transmitted ID code
matches the ID code registered in the
immobilizer system, the system allows the
engine to be started. Since the ID code is
transmitted and acted upon almost in-
