Front seatbelt pretensioners
The 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 curtainairbag.
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 ”F 1-17.
. 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 monitors
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. For details,
refer to “SRS airbag system monitors ”F 1-
71.
& 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. Do not use elec-
trical test equipment on any
circuit related to the seatbelt
pretensioner and airbag sys-
tems. 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. 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. &
Precautions against vehicle modification
Always consult your SUBARU dealer if
you want to install any accessory parts to
your vehicle.
CAUTION
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the seatbelt pretensioners. . Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts to
the front end.
. Modification of the suspension
system or front end structure.
. Installation of a tire of different
size and construction from the
tires specified on the vehicle
placard attached to the door
pillar or specified for individual

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 illuminates, have the system
inspected by your SUBARU dealer im-
mediately if the SRS airbag system warn-
ing light illuminates. NOTE
The driver
’s SRS side airbag, SRS
curtain airbag and seatbelt preten-
sioner are not controlled by the
SUBARU advanced frontal airbag sys-tem. ! 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
advanced frontal airbag system from
functioning 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 system is designed to determine the
activation or deactivation condition of the
front passenger
’s SRS frontal airbag
depending on the total load on the frontpassenger ’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 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 imme-
diately 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 short-
er than the blink of an eye.
When only the driver ’s SRS frontal airbag
deploys and both 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

A hands-free microphone or
other accessory in such a loca-
tion could be propelled through
the cabin with great force by the
curtain airbag, or it could prevent
correct deployment of the curtain
airbag. In either case, the result
could be serious injuries.
WARNING
Do not hang coat hangers or other
hard or pointed objects on the coat
hooks. If such items were hanging
on the coat hooks during deploy-
ment of the SRS curtain airbags,
they could cause serious injuries by
coming off the coat hooks and being
thrown through the cabin or by 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 the front 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 be-
cause each has its own impact sensor.
Therefore, they may not both deploy in the
same accident. Also, the SRS side airbag
and SRS curtain airbag deploys indepen-
dently of the driver ’s and front passen-
ger ’s SRS frontal airbags in the steering
wheel and instrument panel.
An impact sensor, which senses impact
force, is located in each of the left and Seat, seatbelt and SRS airbags
1-63

right center pillars and rear wheel houses.
Another impact sensor, which also senses
impact force, is located under the second-
row center seat. In addition, a rollover
sensor is located inside the airbag controlmodule.
If one of the center pillar impact sensors
and the impact sensor that is located
under the second-row center seat to-
gether sense 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. At this time,
the driver ’s and front passenger ’s seatbelt
pretensioners also operate at the sametime.
If one of the rear wheel house impact
sensors and the impact sensor that is
located under the second-row center seat
together sense an impact force above a
predetermined level in a side collision, 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
SRS curtain airbags. At this time, the
driver ’s and front passenger ’s seatbelt pretensioners also operate at the sametime.
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 isapplied.
When the SRS side airbag and SRS
curtain airbag deploy, a sudden, fairly loud
inflation noise will be heard and some
smoke will be released. These occur-
rences are a normal result of the deploy-
ment. This smoke does not indicate a fire
in the vehicle.
CAUTION
Do not touch the SRS side airbag
system components around the
front seat seatback with bare hands
right after deployment. Doing so can
cause burns because the compo-
nents can be very hot as a result of deployment.
After deployment, do not touch any
part of the SRS curtain airbag
system (from the front pillar to the
part of the roof side over the
second-row seat). Doing so can
cause burns because the compo-
nents can be very hot as a result ofdeployment.
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. Also, in the
case of a rollover, the SRS curtain airbag
deploys. They are not designed to deploy
in most lesser side impact. Also, they are
not designed to deploy in most frontal or
most rear impacts because SRS side
airbag and SRS curtain airbag deploy-
ment would not help the occupant in thosesituations.
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
