Seatbelt pretensionersThe following seatbelts have a seatbelt
pretensioner.
.Driver’s seatbelt
.Front passenger’s seatbelt
The seatbelt pretensioners are designed
to be activated in the event of an accident
involving a moderate to severe frontal and
side collision and rollover accident.
WARNING
.To obtain maximum protection,
the occupants should sit in an
upright position with their seat-
belts properly fastened. Refer to
“Seatbelts”F1-12.
.Do not modify, remove or strike
the seatbelt retractor assemblies
equipped with seatbelt preten-
sioners or surrounding area. This
could result in accidental activa-
tion of the seatbelt pretensioners
or could make the system inop-
erative, possibly resulting in ser-
ious injury. Seatbelt preten-
sioners have no user-serviceable
parts. For required servicing of
seatbelt retractors equipped with
seatbelt pretensioners, consultyour SUBARU dealer.
.When discarding seatbelt retrac-
tor assemblies equipped with
seatbelt pretensioners or scrap-
ping the entire vehicle due to
collision damage or for other
reasons, consult your SUBARU
dealer.
NOTE.Seatbelt pretensioners are not de-
signed to activate in minor impacts or
in rear impacts.
.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 a seatbelt that has a seatbelt
pretensioner does not retract or cannot
be pulled out due to a malfunction or
activation of the pretensioner, contact
your SUBARU dealer as soon as pos-
sible.
.If the seatbelt retractor assembly or
surrounding area has been damaged,
contact your SUBARU dealer as soonas possible.
.When you sell your vehicle, we urge
you to inform the buyer that the vehicle
is equipped with seatbelt preten-
sioners. Also, notify the buyer of the
contents in this section.

.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, any
seatbelt that has a seatbelt pretensioner is
quickly drawn back in by the retractor to
take up the slack so that the belt more
effectively restrains the seat occupant.
The driver’s seatbelt pretensioner includes
a tension reducing device which limits the
peak forces exerted by the seatbelt on the
occupant in the event of a collision.
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.!In cases of rollover accident, frontal
collisions or side collisions, the
following components will operate
simultaneously
For details, refer to“In cases of rollover
accident, frontal collisions or side colli-
sions, the following components will oper-
ate simultaneously”F1-23.
&Seatbelt with shoulder belt
and lap belt pretensioners
NOTEThis section is applicable to the front
passenger’s side seatbelt.1) Seatbelt retractor assembly (shoulder
belt pretensioner and adaptive force
limiter)
2) Lap belt pretensioner
On the front passenger’sside,the
shoulder belt pretensioner is supplemen-
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 collision force is detected. As a
result, the seatbelt restrains the front seat
occupant more effectively.
The front passenger’s seatbelt preten-
sioner includes a tension reducing device
which limits the peak forces exerted by the
seatbelt on the occupant in the event of a
collision.
The adaptive force limiter will select a
reducing load to the suit body size of
occupant as detected by the occupant
detection sensor.
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 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.1) Occupant detection sensorsThe occupant detection system sensors
are installed between the seat and seat
rails, and monitor the physique and pos-
ture of the front passenger. Using this
information, the occupant detection sys-
tem determines whether the front passen-
ger’s SRS frontal airbag should be de-
ployed or not.
The occupant detection system may not
inflate the front passenger’s SRS frontal
airbag even when the driver’s SRS frontalairbag 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“Seatbelt preten-
sioners”F1-21.
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’sseat.
.Do not place anything (shoes,
umbrella, etc.) under the front
passenger’s seat.
.Do not place any objects (books,
etc.) around the front passen-
ger’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 vehi-
cle.
.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
forward-backward 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“Forward and backward
adjustment”F1-5 and“Reclining
the seatback”F1-5.

!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.
