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 moderate to severe frontal and
side collisions and rollover accidents.
& Seatbelt with shoulder belt
pretensioner
NOTE
This section is applicable to the dri-
ver ’s side seatbelt.
The pretensioner sensor also serves as
follows.
. SRS frontal airbag sensor .
Side impact sensor
. Front door impact sensor
. Rollover sensor
If the sensor detects a certain predeter-
mined amount of force during frontal or
side collisions or rollover accidents, the
front seatbelt is quickly drawn back in by
the retractor to take up the slack so that
the belt more effectively restrains the
driver.
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 cannot
be pulled out and retracted and therefore
must be replaced.
NOTE
. Seatbelt pretensioners are not de-
signed to activate in minor impacts or
in rear impacts.
. In cases of rollover accidents, as the
curtain airbags deploy, the driver ’s side
seatbelt pretensioner and front passen-
ger ’s side shoulder belt pretensioner are activated simultaneously.
.
In cases of frontal collisions, the
following components will operate si-
multaneously.
–Seatbelt pretensioner for driver
– Seatbelt pretensioner for front
passenger
– SRS frontal airbag for driver
– SRS frontal airbag for front pas-
senger*
– SRS side airbags (both sides) (if
an offset frontal collision occurs)
– SRS curtain airbags (both sides)
(if an offset frontal collision occurs)
*: This does not operate if the occupant
detection system deactivates airbag op-
eration. For details, refer to “Front
passenger ’s SRS frontal airbag ”F 1-51
.
. In cases of side collisions, the
following components will operate si-
multaneously.
–SRS curtain airbag (impacted
side)
– SRS side airbag (impacted side)
(when both the satellite safing sen-
sor and any of the center pillar
impact sensors/front door impact
sensors sense an impact force)

However, when a center pillar im-
pact sensor detects a signal faster
than the front door impact sensor,
or both sensors detect signals
simultaneously, the seatbelt preten-
sioner does not activate.
. 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 should
be replaced 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 the
buyer to the contents of this section.
WARNING
. To obtain maximum protection,
the occupants should sit in an
upright position with their seat-
belts properly fastened. Refer to
“ Seatbelts ”F 1-16.
. 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, consult your 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.
& Seatbelt with shoulder belt
and lap belt pretensioners
NOTE
This section is applicable to the front
passenger ’s side seatbelt.
1) Seatbelt retractor assembly (shoulder
belt pretensioner)
2) Lap belt pretensioner
On the front passenger ’s side, the
shoulder belt pretensioner is supplemen-
1-26

ted by a lap belt pretensioner, which is
located at the base of the center pillar.
Like the shoulder belt pretensioner, the lap
belt pretensioner instantaneously pulls in
the belt to eliminate slack if a certain level
of frontal or side collision force or a
rollover accident is detected. As a result,
the seatbelt restrains the front seat occu-
pant more effectively.
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 pretensioner re-
mains locked. Consequently, the seatbelt
cannot be pulled out and retracted and
therefore must be replaced.
NOTE
.Seatbelt pretensioners are not de-
signed to activate in minor impacts or
in rear impacts.
. In cases of rollover accidents, the
lap belt pretensioner does not activate;
however, as the curtain airbags deploy,
the driver ’s side seatbelt pretensioner
and front passenger ’s side shoulder
belt pretensioner are activated simulta- neously.
.
In cases of frontal collisions, the
following components will operate si-
multaneously.
–Seatbelt pretensioner for driver
– Seatbelt pretensioners for front
passenger
– SRS frontal airbag for driver

the readiness of the seatbelt pretensioner
while the vehicle is being driven. The
seatbelt pretensioners share the control
module with the SRS 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 1-69.
& 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 SRS
airbag 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 SRS airbag
systems. For required servicing
of the seatbelt pretensioner, con-
sult your nearest SUBARU deal-
er.

&SUBARU advanced frontal
airbag system
Your vehicle is equipped with a SUBARU
advanced frontal airbag system that com-
plies with the new advanced frontal airbag
requirements in the amended Federal
Motor Vehicle Safety Standard (FMVSS)
No. 208.
The SUBARU advanced frontal airbag
system automatically determines the de-
ployment force of the driver ’s SRS frontal
airbag at the time of deployment as well as
whether or not to activate the front
passenger ’s SRS frontal airbag and, if
activated, the deployment force of the
SRS frontal airbag at the time of deploy-
ment.
Your vehicle has warning labels on the
driver ’s and front passenger ’s sun visors
beginning with the phrase “EVEN WITH
ADVANCED AIR BAGS” and a tag
attached to the glove box lid beginning
with the phrase “Even with Advanced Air
Bags”. Make sure that you carefully read
the instructions on the warning labels and
tag.
Always wear your seatbelt. The SUBARU
advanced frontal airbag system is a
supplemental restraint system and must
be used in combination with a seatbelt. All
occupants should wear a seatbelt or be
seated in an appropriate child restraint system.
For the locations of the SRS airbags, refer
to
“Components ”F 1-49.
In a moderate to severe frontal collision,
the following components deploy.
. SRS frontal airbag for driver
. SRS frontal airbag for front passenger
. SRS knee airbag for driver
. SRS side airbag*
1
.SRS curtain airbag*1
*1: When an offset frontal collision that is severe
enough to deploy the front airbag occurs.
These components supplement the seat-
belts by reducing the impact to the
occupant ’s head, chest and knees.
! 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.
Have the system inspected by your
SUBARU dealer immediately if the SRS
airbag system warning light illuminates.
! 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 occupant detection system sensor is
installed under the seat upholstery and
monitors the physique and posture of the
front passenger. Using this information,
the occupant detection system determines
whether the front passenger
’s SRS frontal
airbag should be deployed or not.
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. In this
case, although the front passenger ’s SRS
frontal airbag does not operate, the front
passenger ’s seatbelt pretensioner oper-
ates with the driver ’s seatbelt preten-
sioner. For details about the seatbelt
pretensioner, refer to “Front seatbelt pre-
tensioners ”F 1-25.
CAUTION
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.
. Do not apply any strong impact
to the front passenger ’s seat
such as by kicking.
. Do not let rear passengers rest
their feet between the front seat-

back and seat cushion.
. Do not spill liquid on the front
passenger ’s seat. If liquid is
spilled, wipe it off immediately.
. Do not remove or disassemble
the front passenger ’s seat.
. Do not install any accessory
(such as an audio amplifier) other
than a genuine SUBARU acces-
sory under the front passenger ’s
seat.
. Do not place anything (shoes,
umbrella, etc.) under the front
passenger ’s seat.
. Do not use the front passenger ’s
seat with the head restraint re-
moved.
. Do not leave any articles on the
front passenger ’s seat or the
seatbelt tongue and buckle en-
gaged when you leave your ve-
hicle.
. Do not put sharp object(s) on the
seat or pierce the seat uphols-
tery.
. Do not place a magnet near the
seatbelt buckle and the seatbelt
retractor.
. Do not use front seats with their
backward-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
“Manual seat ”F1-4
(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
warning light will illuminate. Have the
system inspected by your SUBARU deal-
er immediately if the SRS airbag system
warning light illuminates.
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. Do not use the front
passenger ’s seat while driving the vehicle
to your SUBARU dealer.
! Passenger ’s frontal airbag ON and
OFF indicators
Refer to “Front passenger ’s frontal airbag
ON and OFF indicators ”F 3-16.
! Occupant detection system
The occupant detection system sensor is
installed under the seat upholstery and
monitors the physique and posture of the
front passenger. Using this information, the occupant detection system determines
whether the front passenger
’s SRS frontal
airbag should be deployed or not.
If the front passenger ’s seat cushion is
wet, this may adversely affect the ability of
the system to determine deployment. If
the seat cushion is wet, the front passen-
ger should stop sitting on the front
passenger ’s seat. Wipe off liquid from
the seat immediately, let the seat dry
naturally and then check that the front
passenger ’s frontal airbag ON and OFF
indicators

work properly.

!Operation
A) Driver ’s side
B) Passenger ’s side
1) SRS AIRBAGs deploy as soon as a collision occurs.
2) After deployment, SRS AIRBAGs start to deflate immediately so that the driver ’s vision is not
obstructed.
The SRS airbags 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 characteristic of item
(s) or person on the front passenger ’s seat
monitored by the front passenger ’s occu-
pant detection system 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 following sensors 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).
. the front sub sensors
. the impact sensors in the airbag control
module
On the driver ’s side, the SRS knee airbag
also inflates with the SRS frontal airbag.
