1-24Seat, seatbelt and SRS airbags
Front seatbelt pretensioners
The driver ’s and front passenger ’s seat-
belts have a seatbelt pretensioner. The
seatbelt pretensioners are designed to be
activated in the event of an accident
involving a moderate to severe frontalcollision.
The pretensioner sensor also serves as a
SRS frontal airbag sensor. If the sensor
detects a certain predetermined amount of
force during a frontal collision, the front
seatbelt is quickly drawn back in by the
retractor to take up the slack so that the
belt more effectively restrains the front
seat occupant.
When a seatbelt pretensioner is activated,
an operating noise will be heard and a small amount of smoke will be released.
These occurrences are normal and not
harmful. This smoke does not indicate a
fire in the vehicle.
Once the seatbelt pretensioner has been
activated, the seatbelt retractor remains
locked. Consequently, the seatbelt can not
be pulled out and retracted and therefore
must be replaced.
NOTE . Seatbelt pretensioners are not de-
signed to activate in minor frontal
impacts, in side or rear impacts or in
roll-over accidents.. The driver ’s seat and passenger ’s
seat pretensioners and frontal airbag
operate simultaneously.. Pretensioners are designed to func-
tion on a one-time-only basis. In the
event that a pretensioner is activated,
both the driver ’s and front passenger ’s
seatbelt retractor assemblies must be
replaced and only by an authorized
SUBARU dealer. When replacing seat-
belt retractor assemblies, use only
genuine SUBARU parts.. If either front seatbelt does not
retract or cannot be pulled out due to
a malfunction or activation of the
pretensioner, contact your SUBARU
dealer as soon as possible. .
If the front seatbelt retractor assem-
bly or surrounding area has been
damaged, contact your SUBARU dealer
as soon as possible.. When you sell your vehicle, we urge
you to explain to the buyer that it has
seatbelt pretensioners by alerting him
to the contents of this section.
WARNING
. To obtain maximum protection,
occupants should sit in an up-
right position with their seatbelts
properly fastened. Refer to “Seat-
belts ”section in this chapter.
. Do not modify, remove or strike
the front seatbelt retractor as-
semblies or surrounding area.
This could result in accidental
activation of the seatbelt preten-
sioners or could make the sys-
tem inoperative, possibly
resulting in serious injury. Seat-
belt pretensioners have no user-
serviceable parts. For required
servicing of front seatbelt retrac-
tors equipped with seatbelt pre-
tensioners, see your nearest
SUBARU dealer.
. When discarding front seatbelt
retractor assemblies or scrap-

ping the entire vehicle due to
collision damage or for other
reasons, consult your SUBARU
dealer.
& System monitors
SRS airbag system warning light (Turbo models)
SRS airbag system warning light (Non-
turbo models)
A diagnostic system continually monitors
the readiness of the seatbelt pretensioner
while the vehicle is being driven. The
seatbelt pretensioners share the control
module with the airbag system. Therefore,
if any malfunction occurs in a seatbelt
pretensioner, the SRS airbag system
warning light will illuminate. The SRS
airbag system warning light will show
normal system operation by lighting for
approximately 6 seconds when the igni-
tion switch is turned to the “ON ”position.
The following components are monitored
by the indicator: . Front sub sensor (Right-hand side)

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. 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
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. . 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

System servicing
WARNING
. When discarding a seatbelt re-
tractor assembly or scrapping
the entire vehicle damaged by a
collision, consult your SUBARU
dealer.
. Tampering with or disconnecting
the system ’s wiring could result
in accidental activation of the
seatbelt pretensioner and/or air-
bag or could make the system
inoperative, which may result in
serious injury. The wiring har-
nesses of the seatbelt preten-
sioner and SRS airbag systems
are covered with yellow insula-
tion and the connectors of the
system are yellow for easy iden-
tification. Do not use electrical
test equipment on any circuit
related to the seatbelt preten-
sioner and airbag systems. For
required servicing of the seatbelt
pretensioner, see your nearest
SUBARU dealer.
CAUTION
The front sub sensors are located in
both front fenders and the airbag
control module including the impact
sensors is located under the center
console. If you need service or
repair in those areas or near the
front seatbelt retractors, have an
authorized SUBARU dealer perform
the work.
NOTE
If the front part of the vehicle is
damaged in an accident to the extent
that the seatbelt pretensioner does not
operate, contact your SUBARU dealer
as soon as possible.

WARNING
Do not attach accessories to the
windshield, or fit an extra-wide mir-
ror over the rear view mirror. If the
SRS airbag deploys, those objects
could become projectiles that could
seriously injure vehicle occupants.
! Driver ’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
buckle 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 tofail. . Do not place articles/metal objects or
install 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
bottom surface with his/her feet. . 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
illuminate. Although the driver ’sSRS
frontal airbag can deploy regardless of
the backward-forward adjustment of the
driver ’s seat position even when the
warning light is on, have the system
inspected by your SUBARU dealer im-
mediately if the SRS airbag system warn-
ing light comes on. NOTE
The driver
’s SRS side airbag, SRS
curtain airbag and seatbelt preten-
sioner are not controlled by the Subaru
advanced frontal airbag system. ! Front passenger ’s SRS frontal air-
bag
The front passenger ’s SRS frontal airbag
uses a dual stage inflator. The inflator
operates 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
monitors the tension of the front passen-
ger seatbelt. Using the total seat load and
seatbelt tension data from the sensors,
the occupant detection system determines
whether the front passenger ’s SRS frontal
airbag should or should not be inflated.
The occupant detection 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. Seat, seatbelt and SRS airbags

! Operation
1) Driver ’s side
2) Passenger ’s side
The SRS airbag can function only when
the ignition switch is in the “ON ”position.
The Subaru advanced frontal airbag sys- tem is designed to determine the activa-
tion or deactivation condition of the frontpassenger
’s SRS frontal airbag depend-
ing on the total load on the front passen-
ger ’s seat monitored by the front
passenger ’s occupant detection system
weight sensor. For this reason, only thedriver ’s SRS frontal airbag may deploy in
the event of a collision, but this does not
mean failure of the system.
If the front sub sensors inside both front
fenders and the impact sensors in the
airbag control module detect a predeter-
mined amount of force during a frontal
collision, the control module sends signals
to the airbag module(s) (only driver ’s
module or both driver ’s and front passen-
ger ’s modules) instructing the module(s)
to inflate the SRS frontal airbag(s). Thedriver ’s and front passenger ’s SRS frontal
airbags use dual stage inflators. The two
inflators of each airbag are triggered either
sequentially or simultaneously, depending
on the severity of impact, backward-
forward adjustment of the driver ’s seat
position and fastening/unfastening of the
seatbelt in the case of the driver ’s SRS
frontal airbag and depending on the
severity of impact and the total load on
the seat in the case of the front passen-ger ’s SRS frontal airbag. After deploy-
ment, the SRS airbag immediately starts to deflate so that the driver
’s vision is not
obstructed. The time required from detect-
ing impact to the deflation of the SRS
airbag after deployment is shorter than the
blink of an eye.
Both when only the driver ’s SRS frontal
airbag deploys and the driver ’s and front
passenger ’s SRS frontal airbags deploy,
the driver ’s and front passenger ’s seatbelt
pretensioners operate at the same time.
Although it is highly unlikely that the SRS
airbag would activate in a non-accident
situation, should it occur, the SRS airbag
will deflate quickly, not obscuring vision
and will not interfere with the driver ’s
ability to maintain control of the vehicle.
When the SRS airbag deploys, a sudden,
fairly loud inflation noise will be heard and
some smoke will be released. These
occurrences are a normal result of the
deployment. This smoke does not indicate
a fire in the vehicle.
