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.
The pretensioner sensor also serves as
follows.
. SRS frontal airbag sensor
. Side impact sensor (front door impact
sensor)
& Seatbelt with shoulder belt
pretensioner
NOTE This section is applicable to the dri-
ver ’ s side seatbelt. Front seatbelt pretensioner
If the sensor detects a certain predeter-
mined amount of force during frontal or
side collisions, 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 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 1-40
.
. 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.
– 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

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 1-11.
. 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
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, the1-18

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 or side collision force is detected.
As a result, the seatbelt restrains the front
seat occupant 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.

position such as one thrown toward
the front of the vehicle during pre-
accident braking.
WARNING
. Do not put any objects over the
steering wheel pad and dash-
board. If the SRS frontal airbag
deploys, these objects could in-
terfere with its proper operation
and could be propelled inside the
vehicle, causing injury.
. Do not put any objects under the
driver ’ s side of the instrument panel. If the knee airbag deploys,
those objects could interfere with
its proper operation and could be
propelled inside the vehicle,
causing injury.
. The key must not be attached to
heavy, sharp or hard acces-
sories, or another key. If the knee
airbag deploys, those objects
could interfere with its proper
operation and could be propelled
inside the vehicle and cause
injury.
WARNING
Do not attach accessories to the
windshield, or fit an extra-wide mir- ror over the inside rear view mirror.
If the SRS airbag deploys, those
objects could become projectiles
that could seriously injure vehicle
occupants.
! 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,1-40

indicator
/ : Front passenger ’ s frontal airbag OFF
indicator
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.
. 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 have
the 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. CAUTIONElectrical devices, such as cell
phones, laptops, portable music
players, or electronic games, espe-
cially when connected to the acces-
sory power outlet and placed on the
front passenger ’ s seat or used by
the person sitting in the front pas-
senger ’ s seat, may affect the opera-
tion of the occupant detection sys-
tem. If the occupant detection sys-
tem warning light illuminates or
operates erratically when using an
electronic device in the vehicle, at
first try to relocate that device to
avoid it creating any interference. If
the device continues to cause inter-
ference, the use of that device in the
vehicle should be discontinued.
