&Seatbelt maintenanceTo clean the seatbelts, use a mild soap
and lukewarm water. Never bleach or dye
the belts because this could seriously
affect their strength.
Inspect the seatbelts and attachments
including the webbing and all hardware
periodically for cracks, cuts, gashes,
tears, damage, loose bolts or worn areas.
Replace the seatbelts even if only minor
damage is found.
CAUTION
. Keep the belts free of polishes,
oils, chemicals and particularly
battery acid.
. Never attempt to make modifica-
tions or changes that will prevent
the seatbelt from operating prop-
erly.
Front seatbelt pretensionersThe driver ’s and front passenger ’s seat-
belts have a seatbelt pretensioner. The
seatbelt pretensioners for the driver ’s seat
and front passenger ’s seat operate at the
same time as the frontal, and side SRS
airbags. If the vehicle rolls over, they
operate simultaneously with the curtain
airbag.
The front and side airbag sensors and the
rollover sensor are used as the preten-
sioner sensors. If a sensor detects a
certain predetermined amount of force
during a frontal collision, a side impact
collision or a rollover collision of the
vehicle, 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 minor side impacts or rear
impacts.
. The seatbelt pretensioners for the
driver ’s seat and front passenger ’s
seat operate at the same time as the
frontal, and side SRS airbags. If the
vehicle rolls over, they operate simul-
taneously with the curtain airbag.
. 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 result-
ing in serious injury. Seatbelt
pretensioners have no user-ser- viceable parts. For required ser-
vicing of front seatbelt retractors
equipped with seatbelt preten-
sioners, 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 monitorsSRS airbag system warning lightA 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)
. Front sub sensor (Left-hand side)
. Airbag control module (including im-
pact and rollover sensors)

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.

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
on both sides of the radiator panel,
and the airbag control module in-
cluding the impact sensors is lo-
cated under the center console. If
you need service or repair in those
areas or near the front seatbelt
retractors, we recommend that you
have an authorized SUBARU dealer
perform the work.NOTEIf 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.

Seat, seatbelt and SRS airbags
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 to
fail.
. 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.
NOTEThe 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 occupant detection system ’s weight
sensor located 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.
. Do not apply any strong impact to the
ProCarManuals.com

The Subaru advanced frontal airbag sys-
tem is designed to determine the activa-
tion or deactivation condition of the front
passenger’s SRS frontal airbag depend-
ing on the total load on the front passen-
ger ’s seat monitored by the front passen-
ger ’s occupant detection system weight
sensor. For this reason, only the driver ’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 located on both
sides of the radiator panel and the impact
sensors in the airbag control module
detect a predetermined 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 passenger ’s modules)
instructing the module(s) to inflate the
SRS frontal airbag(s). The driver ’s and
front passenger ’s SRS frontal airbags use
dual stage inflators. The two inflators of
each airbag are triggered either sequen-
tially or simultaneously, depending on the
severity of impact, backward-forward ad-
justment 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 passenger ’s SRS frontal airbag. After deployment, the SRS airbag immediately
starts to deflate so that the driver
’s vision
is not obstructed. The time required from
detecting 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.
CAUTION
Do not touch the SRS airbag system
components around the steering
wheel and dashboard with bare
hands right after deployment. Doing
so can cause burns because the components can be very hot as a
result of deployment.
The driver ’s SRS frontal airbag and front
passenger ’s SRS frontal airbag are de-
signed to deploy in the event of an
accident involving a moderate to severe
frontal collision. It is basically not designed
to deploy in lesser frontal impacts be-
cause the necessary protection can be
achieved by the seatbelt alone. Also, they
are basically not designed to deploy in
side or rear impacts or in rollover acci-
dents because deployment of only the
driver ’s SRS frontal airbag or both driver ’s
and front passenger ’s SRS frontal airbags
would not help the occupant in those
situations. The driver ’s and front passen-
ger ’s SRS frontal airbags are designed to
function on a one-time-only basis.
SRS airbag deployment depends on the
level of force experienced in the passen-
ger compartment during a 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.

preventing deployment of the cur-
tain airbags.
Before hanging clothing on the coat
hooks, make sure there are no sharp
objects in the pockets. Hang cloth-
ing directly on the coat hooks with-
out using hangers.
WARNING
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
surface on or near the SRS side
airbag. They could prevent proper
deployment of the SRS side airbag,
reducing protection available to thefront seat
’s occupant.
! Operation
The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the “ON”position.
The driver ’s and front passenger ’s SRS
side airbags and SRS curtain airbags
deploy independently of each other since
each has its own impact sensor. There-
fore, they may not both deploy in the same
accident. Also, the SRS side airbag and
SRS curtain airbag deploys independently
of the driver ’s and front passenger ’s SRS
frontal airbags in the steering wheel and
instrument panel.
An impact sensor is located in each of the left and right center pillars and rear wheel
houses. In addition, the rollover sensor is
inside the airbag control module. If a
center pillar impact sensor senses an
impact force above a predetermined 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. If it is a rear wheel
house impact sensor alone that senses a
sufficiently strong impact force, the control
module causes only the SRS curtain
airbag on the impacted side to inflate. If
the rollover sensor detects rollover of the
vehicle, the control module inflates the
curtain airbag. After 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.
