Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
&Seatbelt maintenance
To 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 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 a moderate to severe frontal
and side collision and rollover accident.
& Seatbelt with shoulder belt
pretensioner
NOTE
This section is applicable to the follow-
ing components.
. Except Crosstrek models:
– Driver ’s seatbelt
– Front passenger ’s seatbelt
. Crosstrek models:
– Driver ’s seatbeltThe pretensioner sensor also serves as
follows.
. SRS frontal airbag sensor
. Side impact sensor
. Front door impact sensor
. Rollover sensor (Crosstrek models)
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
1-20 

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 impacts or
in rear impacts.
. In the case of rollover accidents
– Crosstrek models:
As the curtain airbags deploy, the
driver ’s side seatbelt pretensioner
and front passenger ’sside
shoulder belt pretensioner are acti-
vated simultaneously.
– Except Crosstrek models:
Seatbelt pretensioners are not acti-
vated.
. 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 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 1-48
.
. 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)
– Seatbelt pretensioner for driver
(when both the satellite safing sen-
sor and the driver ’s side front door
impact sensor 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.
– Seatbelt pretensioner for front
passenger (shoulder belt preten-
sioner only) (when both the satellite
safing sensor and the front passen-
ger ’s side front door impact sensor
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.

belts properly fastened. Refer to
“Seatbelts ”F 1-11.
. 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

Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
&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” F1-46.
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.
Have the system inspected by your
SUBARU dealer immediately if the SRS
airbag system warning light illuminates.
NOTE
The 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.
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 1-20.
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.
1-48 

.Do not apply any strong impact
to the front passenger ’sseat
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
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” F1-3 and “Reclining
the seatback ”F 1-4.
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.
NOTE
The front passenger ’s SRS side airbag
and SRS curtain airbag are not con-
trolled by the SUBARU advanced fron- tal airbag system.
!
Passenger ’s frontal airbag ON and
OFF indicators
Refer to “Front passenger ’s frontal airbag
ON and OFF indicators” F3-16.
! 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 the SRS airbag
system warning light as follows.
