&Head restraint adjustment
WARNING
.Never drive the vehicle with the
head restraints removed because
they are designed to reduce the
risk of serious neck injury in the
event that the vehicle is struck
from the rear. Also, never install
the head restraints the opposite
way around. Doing so will pre-
vent the head restraints from
functioning as intended. There-
fore, when you remove the head
restraints, you must reinstall all
head restraints correctly to pro-
tect vehicle occupants.
.All occupants, including the dri-
ver, should not operate a vehicle
or sit in a vehicle’s seat until the
head restraints are placed in their
proper positions in order to mini-
mize the risk of neck injury in the
event of a crash.
Both the driver’s seat and front passen-
ger’s seat are equipped with head re-
straints. Both head restraints are adjusta-
ble in the following ways.!Head restraint height adjustment
1) Head restraint
2) Release button
Each head restraint should be adjusted so
that the center of the head restraint is
closest to the top of the occupant’s ears.
To raise:
Pull the head restraint up.
To lower:
Push the head restraint down while
pressing the release button on the top of
the seatback.
To remove:

Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
CAUTION
.Do not allow the retractor to roll
up the seatbelt too quickly.
Otherwise, the metal tongue
plates may hit against the trim,
resulting in damaged trim.
.Have the seatbelt fully rolled up
so that the tongue plates are
neatly stored. A hanging tongue
plate can swing and hit against
the trim during driving, causing
damage to the trim.
&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 moderate to severe frontal and
side collisions and rollover accidents.
The pretensioner sensor also serves as
follows.
.SRS frontal airbag sensor
.Side 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
1-24

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.
.In cases of rollover accidents, as the
SRS curtain airbags deploy, the seat-
belt pretensioners are activated simul-
taneously.
.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 seat cushion airbag fordriver
–SRS seat cushion airbag for front
passenger*
–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”F1-52
.
.In cases of side collisions, the
following components will operate si-
multaneously.
–SRS curtain airbag (impacted
side)
–SRS side airbag (impacted side)
(when any of the center pillar im-
pact sensors/front door impact sen-
sors senses an impact force)
–Seatbelt pretensioner for driver
(when the driver’s side front door
impact sensor senses an impact
force)
–Seatbelt pretensioner for front
passenger (when the front passen-
ger’s side front door impact sensor
senses an impact force)
.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 authorizedSUBARU 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”F1-16.
.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

Seat, seatbelt and SRS airbags/Front seatbelt pretensioners
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.
&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
modulewiththeSRSairbagsystem.
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”F1-68.
&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
systems. For required servicing
of the seatbelt pretensioner, con-
sult your nearest SUBARU deal-
er.
CAUTION
The sensors and SRS airbag control
modules are located in the following
locations.
.Front sub sensors: on both sides
of the radiator panel
.Front door impact sensors: on
both front doors
.SRS airbag control module (in-
cluding the impact sensors and
rollover sensor): under the cen-
ter console
If you need service or repair in those
areas or near the front seatbelt
retractors, have the work performed
by your authorized SUBARU dealer.
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.

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 asupplemental 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.
Your vehicle is equipped with a SUBARU
SRS curtain airbag system that complies
with the Federal Motor Vehicle Safety
Standard (FMVSS) No. 226.
For the locations of the SRS airbags, refer
to“Components”F1-48.
In a moderate to severe frontal collision,
the following components deploy.
.SRS frontal airbag for driver
.SRS frontal airbag for front passenger
.SRS seat cushion airbags
.SRS curtain airbag*

*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 and chest.
Inamoderatetoseveresideimpact
collision, the SRS side airbag on the
impacted side of the vehicle deploys
between the occupant and the door panel
and supplements the seatbelt by reducing
the impact to the occupant’s chest and

In a moderate to severe side impact
collision, the SRS curtain airbag on the
impacted side of the vehicle deploys
between the occupant and the side
window and supplements the seatbelt by
reducing the impact to the occupant’s
head.
NOTE
The SRS side airbag and seatbelt
pretensioner are not controlled by the
SUBARU advanced frontal airbag sys-
tem.
!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 total load on the seat is monitored by
the passenger’s occupant detection sys-tem sensor located under the seat.
The system has another sensor that
monitors the tension of the front passen-
ger’s seatbelt. Using the total seat load
and seatbelt tension data from the sen-
sors, the occupant detection system de-
termines 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.
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’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 disassemblethe 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 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).
