Front seatbelt pretensioners
The driver’s and front passenger’s seat-
belts have a seatbelt pretensioner. The
seatbelt pretensioners for the driver’s seat
and front passenger’s seat operate at the
same time as the frontal, and side SRS
airbags.
The pretensioner sensor also serves as
the frontal and side SRS airbag sensors. If
the sensor detects a certain predeter-
mined amount of force during a frontal col-
lision or a side impact collision, the front
seatbelt is quickly drawn back in by the re-
tractor to take up the slack so that the belt
more effectively restrains the front seat
occupant. 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 there-
fore must be replaced.
NOTE y
Seatbelt pretensioners are not de-
signed to activate in minor frontal im-
pacts, in minor side impacts or rear im-
pacts or in roll-over accidents. y The seatbelt pretensioners for the
driver’s seat and front passenger’s
seat operate at the same time as the
frontal, and side SRS airbags. y 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 must be
replaced and only by an authorized
SUBARU dealer. When replacing seat-
belt retractor assemblies, use only
genuine SUBARU parts. y If either front seatbelt does not re-
tract or cannot be pulled out due to a malfunction or activation of the preten-
sioner, contact your SUBARU dealer as
soon as possible.y
If the front seatbelt retractor assem-
bly or surrounding area has been dam-
aged, contact your SUBARU dealer as
soon as possible. y When you sell your vehicle, we urge
you to explain to the buyer that it has
seatbelt pretensioners by alerting him
to the contents of this section.
100121y To obtain maximum protection,
occupants should sit in an upright
position with their seatbelts prop-
erly fastened. Refer to “Seatbelts”
section in this chapter.
yDo not modify, remove or strike
the front seatbelt retractor assem-
blies or surrounding area. This
could result in accidental activa-
tion of the seatbelt pretensioners
or could make the system inoper-
ative, possibly resulting in seri-
ous injury. Seatbelt pretensioners
have no user-serviceable parts.
For required servicing of front
seatbelt retractors equipped with
seatbelt pretensioners, see your
nearest SUBARU dealer.

„System monitors
SRS airbag system warning light
A diagnostic system continually monitors
the readiness of the seatbelt pretensioner
while the vehicle is being driven. The seat-
belt pretensioners share the control mod-
ule with the airbag system. Therefore, if
any malfunction occurs in a seatbelt pre-
tensioner, the SRS airbag system warning
light will illuminate. The SRS airbag sys-
tem warning light will show normal system operation by lighting for approximately 6
seconds when the ignition switch is turned
to the “ON” position.

If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbags will operate improperly (e.g.
SRS airbags may inflate in a very mi-
nor collision or not inflate in a se-
vere collision), which may increase
the risk of injury.

er.
yTampering with or disconnecting
the system’s wiring could result in
accidental activation of the seat-
belt pretensioner and/or airbag or
could make the system inopera-
tive, which may result in serious
injury. The wiring harnesses of
the seatbelt pretensioner and SRS
airbag systems are covered with
yellow insulation and the connec-
tors of the system are yellow for
easy identification. Do not use
electrical test equipment on any
circuit related to the seatbelt pre-
tensioner and airbag systems. For
required servicing of the seatbelt
pretensioner, see your nearest
SUBARU dealer.
The front sub sensors are located in
both front fenders and the airbag
control module including the impact
sensors is located under the center
console. If you need service or re-
pair in those areas or near the front
seatbelt retractors, we recommend
that you have an authorized
SUBARU dealer perform the work.
Do not perform any of the following

TDriver’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, backward-forward adjustment
of the driver’s seat position and whether or
not he/she is wearing the seatbelt.
The backward-forward adjustment of the
driver’s seat position is monitored by the
driver’s seat position sensor under the driver’s seat.
Whether or not the driver is wearing the
seatbelt is monitored by the seatbelt buck-le switch.
Observe the following precautions. Failure
to do so may cause the seatbelt buckle
switch and/or the seat position sensor to
malfunction, preventing the Subaru ad-
vanced frontal airbag system from func-
tioning correctly or causing the system to fail. y
Do not place articles/metal objects or in-
stall any accessory other than a genuine
SUBARU accessory under the driver’s
seat. Do not allow the rear seat occupant
to kick the driver’s seat or push up its bot-
tom surface with his/her feet. y Do not place a magnet near the seatbelt
buckle or under the driver’s seat.
If the seatbelt buckle switch and/or the
driver’s seat position sensor have failed,
the SRS airbag system warning light will il-
luminate. Although the driver’s SRS fron-
tal airbag can deploy regardless of the
backward-forward adjustment of the driv-
er’s seat position even when the warning
light is on, have the system inspected by
your SUBARU dealer immediately if the
SRS airbag system warning light comes
on.
NOTE The driver’s SRS side airbag, SRS cur-
tain airbag and seatbelt pretensioner
are not controlled by the Subaru ad-
vanced frontal airbag system. T Front passenger’s SRS frontal air-
bag
The front passenger’s SRS frontal airbag
uses a dual stage inflator. The inflator op-
erates in different ways depending on the
severity of impact.
The total load on the seat is monitored by
the occupant detection system’s weight
sensor located under the seat.
The system has another sensor that mon-
itors the tension of the front passenger
seatbelt. Using the total seat load and
seatbelt tension data from the sensors,
the occupant detection system deter-
mines whether the front passenger’s SRS
frontal airbag should or should not be in-
flated.
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.
Observe the following precautions. Failure
to do so may prevent the Subaru ad-
vanced frontal airbag system from func-
tioning correctly or cause the system to fail.
Do not attach accessories to the
windshield, or fit an extra-wide mir-
ror over the rear view mirror. If the
SRS airbag deploys, those objects
could become projectiles that could
seriously injure vehicle occupants.

1-56 Seat, seatbelt and SRS airbags
TOperation
1) Driver’s side
2) Passenger’s side
The SRS airbag can function only when
the ignition switch is in the “ON” position.
The Subaru advanced frontal airbag sys- tem is designed to determine the activa-
tion or deactivation condition of the front
passenger’s SRS frontal airbag depend-
ing on the total load on the front passen-
ger’s seat monitored by the front passen-
ger’s occupant detection system weight
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 front sub sensors inside both front
fenders and the impact sensors in the air-
bag control module detect a predeter-
mined amount of force during a frontal col-
lision, the control module sends signals to
the airbag module(s) (only driver’s module
or both driver’s and front passenger’s
modules) instructing the module(s) to in-
flate the SRS frontal airbag(s). The driv-
er’s and front passenger’s SRS frontal air-
bags use dual stage inflators. The two in-
flators of each airbag are triggered either
sequentially or simultaneously, depending
on the severity of impact, backward-for-
ward adjustment of the driver’s seat posi-
tion and fastening/unfastening of the seat-
belt in the case of the driver’s SRS frontal
airbag and depending on the severity of
impact and the total load on the seat in the
case of the front passenger’s SRS frontal
airbag. After deployment, the SRS airbag
immediately starts to deflate so that the driver’s vision is not obstructed. The time
required from detecting impact to the de-
flation of the SRS airbag after deployment
is shorter than the blink of an eye.
Both when only the driver’s SRS frontal
airbag deploys and the driver’s and front
passenger’s SRS frontal airbags deploy,
the driver’s and front passenger’s seatbelt
pretensioners operate at the same time.
Although it is highly unlikely that the SRS
airbag would activate in a non-accident
situation, should it occur, the SRS airbag
will deflate quickly, not obscuring vision
and will not interfere with the driver’s abil-
ity to maintain control of the vehicle.
When the SRS airbag deploys, a sudden,
fairly loud inflation noise will be heard and
some smoke will be released. These oc-
currences are a normal result of the de-
ployment. This smoke does not indicate a
fire in the vehicle.

ploy independently of each other since
each has its own impact sensor. There-
fore, they may not both deploy in the same
accident. Also, the SRS side airbag and
SRS curtain airbag deploys independently
of the driver’s and front passenger’s SRS
frontal airbags in the steering wheel and
instrument panel.
An impact sensor is located in each of the
left and right center pillars and rear wheel
houses. If a center pillar impact sensor
senses an impact force above a predeter-
mined level in a side collision, the control
module causes both the SRS side airbag
and curtain airbag on the impacted side to
inflate regardless of whether the rear
wheel house impact sensor on the same
side senses an impact. If it is a rear wheel
house impact sensor alone that senses a
sufficiently strong impact force, the control
module causes only the SRS curtain air-
bag on the impacted side to inflate. After
deployment, the SRS side airbag immedi-
ately starts to deflate. The time required
from detection of an impact to deflation of
an SRS side airbag after deployment is
shorter than the blink of an eye.
The SRS curtain airbag remains inflated
for a while following deployment then
slowly deflates.
The SRS side airbag and SRS curtain air-
bag deploy even when no one occupies
the seat on the side on which an impact is
applied.
When the SRS side airbag and SRS cur-
tain airbag deploy, a sudden, fairly loud in-
flation noise will be heard and some
smoke will be released. These occurrenc-
es are a normal result of the deployment.
This smoke does not indicate a fire in thevehicle.
The SRS side airbag and SRS curtain air-
bag are designed to deploy in the event of
an accident involving a moderate to se-
vere side impact collision. It is basically not designed to deploy in a lesser side im- pact. Also, it is basically not designed to
deploy in frontal or rear impacts because
SRS side airbag and SRS curtain airbag
deployment would not help the occupant
in those situations.Each SRS side airbag and SRS curtain
airbag are designed to function on a one- time-only basis.
SRS side airbag and SRS curtain airbag
deployment depend on the level of force
experienced in the passenger compart-
ment during a side impact collision. That
level differs from one type of collision to
another, and it may have no bearing on
the visible damage done to the vehicle it-self.
Do not touch the SRS side airbag
system components around the
front seat seatback with bare hands
right after deployment. Doing so can
cause burns because the compo-
nents can be very hot as a result of
deployment.
After deployment, do not touch any
part of the SRS curtain airbag sys-
tem (from the front pillar to the part
of the roof side over the rear seat).
Doing so can cause burns because
the components can be very hot as
a result of deployment.

1-66 Seat, seatbelt and SRS airbags
VExamples of the types of accidents
in which the SRS side airbag and
SRS curtain airbag will basically not
deploy.
1) The vehicle is involved in frontal collision with another vehicle (moving or station- ary).
2) The vehicle is struck from behind.
The SRS side airbag and SRS curtain air-
bag are basically not designed to deploy if
the vehicle is involved in a frontal collision
or is struck from behind. Examples of such
accidents are illustrated.
1) First impact
2) Second impact
A) SRS curtain airbag
B) SRS side airbag
In an accident where the vehicle is struck
from the side more than once, the SRS
side airbag and SRS curtain airbag deploy
only once on the first impact.
Example: In the case of a double side im-
pact collision, first with one vehicle and immediately followed by another from the
same direction, once the SRS side airbag
and SRS curtain airbag are activated on
the first impact, they will not be activated
on the second. „
