TDriver’s SRS frontal airbag
The driver’s SRS frontal airbag uses a
dual stage inflator. The inflator operates in
different ways depending on the severity
of impact, backward-forward adjustment
of the driver’s seat position and whether or
not he/she is wearing the seatbelt.
The backward-forward adjustment of the
driver’s seat position is monitored by the
driver’s seat position sensor under the driver’s seat.
Whether or not the driver is wearing the
seatbelt is monitored by the seatbelt buck-le switch.
Observe the following precautions. Failure
to do so may cause the seatbelt buckle
switch and/or the seat position sensor to
malfunction, preventing the Subaru ad-
vanced frontal airbag system from func-
tioning correctly or causing the system to fail. y
Do not place articles/metal objects or in-
stall any accessory other than a genuine
SUBARU accessory under the driver’s
seat. Do not allow the rear seat occupant
to kick the driver’s seat or push up its bot-
tom surface with his/her feet. y Do not place a magnet near the seatbelt
buckle or under the driver’s seat.
If the seatbelt buckle switch and/or the
driver’s seat position sensor have failed,
the SRS airbag system warning light will il-
luminate. Although the driver’s SRS fron-
tal airbag can deploy regardless of the
backward-forward adjustment of the driv-
er’s seat position even when the warning
light is on, have th e system inspected by
your SUBARU dealer immediately if the
SRS airbag system warning light comes
on.
NOTE
The driver’s SRS si de airbag, SRS cur-
tain airbag and seatbelt pretensioner
are not controlled by the Subaru ad-
vanced frontal airbag system. T Front passenger’s SRS frontal air-
bag
The front passenger’s SRS frontal airbag
uses a dual stage inflator. The inflator op-
erates in different ways depending on the
severity of impact.
The total load on the seat is monitored by
the passenger’s occupant detection sys-
tem weight sensor under the seat.
The system has another sensor that mon-
itors the tension of the front passenger
seatbelt. Using the total seat load and
seatbelt tension data from the sensors,
the occupant detection system deter-
mines whether the front passenger’s SRS
frontal airbag should or should not be in-
flated. The occupant detecti on system may not
inflate the front passenger’s SRS frontal
airbag even when the driver’s SRS frontal
airbag deploys. This is normal.
Observe the following precautions. Failure
to do so may prevent the Subaru ad-
vanced frontal airbag system from func-
tioning correctly or cause the system to fail.
Do not attach accessories to the
windshield, or fit an extra-wide mir-
ror over the rear vi ew mirror. If the
SRS airbag deploys, those objects
could become projectiles that could
seriously injure vehicle occupants.

1-46 Seat, seatbelt and SRS airbags
yDo not apply any strong impact to the
front passenger’s seat such as by kicking.
y Do not spill liquid on the front passen-
ger’s seat. If liquid is spilled, wipe it off im-
mediately. y Do not disassemble the front passen-
ger’s seat. y Do not install any accessory (such as
an audio amplifier) other than a genuine
SUBARU accessory under the front pas-
senger’s seat. y Do not place anything (shoes, umbrella,
etc.) under the front passenger’s seat. y The front passenger’s seat must not be
used with the head restraint removed. y Do not leave any article including a child
restraint system on the front passenger’s
seat or the seatbelt tongue and buckle en-
gaged when you leave your vehicle.y Do not place a magnet near the seatbelt
buckle and the seatbelt retractor.y Do not use front seats with their back-
ward-forward position and seatback not
being locked into place securely. If any of
them are not locked securely, adjust them
again. For adjusting procedure, refer to
the “Manual seat” in the front seats sec-
tion in Chapter 1 in this owner’s manual.
(Models equipped with manual seats only)
If the seatbelt buckle switch and/or front
passenger’s occupant detection system
have failed, the SRS airbag system warn- ing light will illumi
nate. Have the system
inspected by your SUBARU dealer imme-
diately if the SRS airbag system warning
light comes on.
If your vehicle has sustained impact, this
may affect the proper function of the
Subaru advanced frontal airbag system.
Have your vehicle inspected at your
SUBARU dealer.
NOTE
The front passenger’s SRS side airbag,
SRS curtain airbag and seatbelt preten-
sioner are not controlled by the Subaru
advanced frontal airbag system. T Passenger’s frontal airbag ON and
OFF indicators
or : Front passenger’s frontal air- bag ON indicator
or : Front passenger’s frontal air- bag OFF indicator
The front passenger’s frontal airbag ON
and OFF indicators show you the status of
the front passenger’s SRS frontal airbag.
The indicators are located between the
map lights.
When the ignition switch is turned to the
“ON” position, both the ON and OFF indi- cators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators ex-
tinguish for 2 seconds. After that, one of
the indicators illuminates depending on
the status of the fr ont passenger’s SRS
frontal airbag determined by the Subaru
advanced frontal airbag system monitor-
ing.
If the front passenger ’s SRS frontal airbag
is activated, the passenger’s frontal airbag
ON indicator will illuminate while the OFF
indicator will remain extinguished.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger’s frontal air-
bag ON indicator will remain extinguished
while the OFF indicator will illuminate.
If both the ON and OFF indicators remain
lit or extinguished simultaneously, the sys-
tem is faulty. Contact your SUBARU deal-
er immediately for an inspection.

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 air-
bag are basically not designed to deploy if
the vehicle is involved in a frontal collision
or is struck from behind. Examples of such
accidents are illustrated.
1) First impact
2) Second impact
A) SRS curtain airbag
B) SRS side airbag
In 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 im-
pact 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 monitors
A 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 “AIRBAG” will
show normal system operation by lighting
for approximately 6 seconds when the ig-
nition switch is turned to the “ON” position.

Front passenger’s frontal airbag ON
and OFF indicatory All related wiring„ SRS airbag system servicing
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to 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 mi-
nor collision or not inflate in a se-
vere collision), which may increase
the risk of injury.
yFlashing or flickering of the warn-
ing light
yNo illumination of the warning
light when the ignition switch is first turned to the “ON” position
yContinuous illumination of the
warning light
yIllumination of the warning light
while driving
yWhen discarding an airbag mod-
ule or scrapping the entire vehicle
damaged by a collision, consult
your SUBARU dealer.
yThe SRS airbag has no user-ser-
viceable parts. Do not use electri-
cal 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 discon-
necting the system’s wiring could
result in accidental inflation of the
SRS airbag or could make the sys-
tem inoperative, which may result
in serious injury. The wiring har-
nesses of the SRS airbag system
are covered with yellow insulation
and system connectors are yellow
for easy identification.
