NOTESeatbelt pretensioners are not de-
signed to activate in minor impacts or
in rear impacts.&Driver’s seatbeltFront seatbelt pretensionerThe 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 pretensioner re-
mains locked. Consequently, the seatbelt
cannot be pulled out and retracted and
therefore must be replaced.
&Front passenger’s seatbelt1) Seatbelt retractor assembly (shoulder
belt pretensioner)
2) Lap belt pretensionerThe shoulder belt pretensioner is supple-
mented 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 is detected.
As a result, the seatbelt restrains the front
seat occupant more effectively.

&Safety tips.Pretensioners are designed to function
on a one-time-only basis. If a pretensioner
is activated, have both front seatbelt
retractor assemblies replaced only by an
authorized SUBARU dealer. When repla-
cing seatbelt 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 assembly
or surrounding area has been damaged,
contact your SUBARU dealer as soon as
possible.
.When you sell your vehicle, we urge
you to inform the buyer that the vehicle is
equipped with seatbelt pretensioners.
Also, notify the buyer of the contents of
this section.&System monitorsA diagnostic system continually monitors
the readiness of the seatbelt pretensioner
with the ignition switch in the“ON”position.
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 willilluminate. For details, refer to“SRS airbag
system monitors”F1-62.
&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 electrical test equipment on
any circuit related to the seatbelt
pretensioner and SRS airbag sys-
tems. For required servicing of
the seatbelt pretensioner, con-
sult your nearest SUBARU deal-
er.

&SUBARU advanced frontal
airbag systemYour 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 deployment.
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 at-
tached 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 restraintsystem.
For the locations of the SRS airbags, refer
to“Components”F1-41.
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 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.
SRS airbag system warning lightHave the system inspected by your
SUBARU dealer immediately if the SRS
airbag system warning light illuminates.NOTEThe driver’s SRS side airbag and SRS
curtain airbag 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.

!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 passenger
should stop sitting on the front passen-
ger’s seat. Wipe off liquid from the seat
immediately, let the seat dry naturally and
then check the SRS airbag system warn-
ing light as follows.
.If the SRS airbag system warning light
illuminates, keep the seat dry until the
warning light turns off. If the SRS airbag
system warning light stays on even when
the seat has dried, do not allow anyone to
sit on the front passenger’s seat and havethe system checked by your SUBARU
dealer.
.If the SRS airbag system warning light
does not illuminate, check that the front
passenger’s frontal airbag ON and OFF
indicators work properly. If the indicators
do not work properly, do not allow anyone
to sit on the front passenger’s seat and
have the system checked by your
SUBARU dealer.
Also, if luggage or electronic devices are
placed on the front passenger’s seat, this
may adversely affect the ability of the
system to determine deployment. This
may prevent the front passenger’s frontal
airbag ON and OFF indicators from work-
ing properly. Check that the indicators
work properly.
When the OFF indicator turns off and the
ON indicator illuminates, the front passen-
ger’s frontal airbag may deploy during a
collision. Remove luggage and electronic
devices from the front passenger’s seat.
CAUTION

!OperationA) 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 de-
pending 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.

!SRS curtain airbag
Your vehicle is equipped with a SUBARU
SRS curtain airbag system that complies
with the Federal Motor Vehicle Safety
Standard (FMVSS) No. 226.
The SRS curtain airbag on each side of the
cabin is stored in the roof side (between
the front pillar and a point over the rear
seat). An“SRS AIRBAG”mark is located
at the top of each center pillar.
Inamoderatetoseveresideimpact
collision, the SRS curtain airbag on the
impacted side of the vehicle deploys
between the occupant and the side win-
dow and supplements the seatbelt by
reducing the impact on the occupant’s
head.
In a rollover, SRS curtain airbags on both
sides of the vehicle deploy between the
occupant and the side window and supple-
ment the seatbelt by reducing the impact to
the occupant’s head.
In an offset frontal collision, SRS curtain
airbags on both sides of the vehicle deploy
between the occupant and the side win-
dow and supplement the seatbelt by
reducing the impact to the occupant’s
head.!Operation
The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the“ON”position.
The following airbags deploy indepen-
dently of each other since each has its
own impact sensor.
.Driver’s SRS side airbag
.Front passenger’s SRS side airbag
.SRS curtain airbag (right-hand side)
.SRS curtain airbag (left-hand side)
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 passenger’s
SRS frontal airbags in the steering wheel
and instrument panel.
An impact sensor, which senses impact
force, is located in each of the following
locations.
.In the left and right front doors
.In the left and right center pillars
.In the left and right rear wheel houses
.Under the rear center seat
.On both sides of the radiator panel
(frontal impact sensor)
The rollover sensor and frontal impact
sensor are located inside the airbagcontrol module, which is located under
the center of the instrument panel.
