Seat, seatbelt and SRS airbags
Front seatbelt pretensioners
The driver’s and front pa
ssenger’s seatbelts have a
seatbelt pretensioner. The seatbelt pretensioners are
designed to be activated in the event of an accident in-
volving a moderate to severe frontal collision.
The pretensioner sensor also serves as a SRS frontal
airbag sensor. If the sensor detects a certain predeter-
mined amount of force during a frontal collision, the
front seatbelt is quickly drawn back in by the retractor
to take up the slack so that the belt more effectively re-
strains the front seat occupant.
When a seatbelt pretensioner is activated, an operat- ing 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.
NOTE y
Seatbelt pretensioners are not designed to acti-
vate in minor frontal impacts, in side or in rear im-
pacts or in roll-over accidents. y The driver’s seat and passenger’s seat preten-
sioners and frontal airbag operate simultaneous- ly. y Pretensioners are designed to function on a
one-time-only basis. In the event that a preten-
sioner is activated, both the driver’s and front pas-
senger’s seatbelt retractor assemblies must be re-
placed and only by an authorized SUBARU dealer.
When replacing seatbelt retractor assemblies, use
only genuine SUBARU parts.y If either front seatbelt does not retract or cannot
be pulled out due to a malfunction or activation of
the pretensioner, contac t your SUBARU dealer as
soon as possible.

The front sub sensors are located in both front
fenders and the airbag control module includ-
ing the impact sensors is located under the
center console. If you need service or repair in
those areas or near the front seatbelt retrac-
tors, have an authorized SUBARU dealer per-
form the work.
NOTE
If the front part of the vehicle is damaged in an ac-
cident to the extent that the seatbelt pretensioner
does not operate, cont act your SUBARU dealer as
soon as possible. „ Precautions against vehicle modifica- tion
Always consult your SUBARU dealer if you want to in-
stall any accessory parts to your vehicle.
Do not perform any of the following modifica-
tions. Such modifications can interfere with
proper operation of the seatbelt pertensioners. y
Attachment of any equipment (bush bar,
winches, snow plow, skid plate, etc.) other than
genuine SUBARU accessory parts to the front
end. y Modification of the suspension system or

Seat, seatbelt and SRS airbags
The SRS airbag can function only when the ignition
switch is in the “ON” position.
If the front sub sensors inside the both front fenders
and the impact sensors in the airbag control module
detect a certain predetermined amount of force during
a frontal collision, the control module sends signals to
the frontal airbag modules instructing them to inflate
the SRS frontal airbags. Then both airbag modules
produce gas, which instantly
inflates driver’s and pas-
senger’s SRS frontal airbags. After deployment, the
SRS airbags immediately starts to deflate so that the
driver’s vision is not obstr ucted. The time required
from detecting impact to the deflation of the SRS air-
bag after deployment is shorter than the blink of aneye.
The front passenger’s SRS frontal airbag deploys to-
gether with driver’s SRS frontal airbag even when no
one occupies the front passenger’s seat.
When the 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 vi-
sion and will not interfere with the driver’s ability 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 occurrences are a normal result of
the deployment. This smoke does not indicate a fire in
the vehicle.
Do not touch the SRS airbag system compo-
nents around the steering wheel and dash-
board with bare hands right after deployment.
Doing so can cause burns because the compo-
nents can be very hot as a result of deployment.
The SRS frontal airbag is designed to deploy in the
event of an accident involving a moderate to severe
frontal collision. It is basically not designed to deploy
in lesser frontal impacts because the necessary pro-
tection can be achieved by the seatbelt alone. Also, it
is basically not designed to deploy in side or rear im-
pacts or in roll-over accidents because deployment of
the SRS frontal airbag would not help the occupant in
those situations. The SRS airbag is designed to func-
tion on a one-time-only basis.
SRS airbag deployment depends on the level of force

in a low-speed frontal collision.
1) First impact!
2) Second impact!!
In an accident where the vehicle is impacted more
than once, the SRS frontal airbag deploys only once.
Example: In the case of a double collision, first with an-
other vehicle, then against a concrete wall in immedi-
ate succession, once the SRS frontal airbag is activat-
ed on the first impact, it will not be activated on the second. „

„ SRS airbag system servicing
yWhen discarding an airbag module or scrap-
ping the entire vehicle damaged by a collision,
consult your SUBARU dealer. y The SRS airbag has no user-serviceable
parts. Do not use electrical test equipment on
any circuit related to the SRS airbag system.
For required servicing of the SRS airbag, see
your nearest SUBARU d ealer. Tampering with
or disconnecting the system’s wiring could re-
sult in accidental inflation of the SRS airbag or
could make the system inoperative, which may
result in serious injury. The wiring harnesses of
the SRS airbag system are covered with yellow
insulation and system connectors are yellow
for easy identification.
If you need service or repair in areas listed in

1-62
Seat, seatbelt and SRS airbags
the following, have an authorized SUBARU
dealer perform the work. The SRS airbag con-
trol module, impact sensors and airbag mod-
ules are stored in these areas. y
Under the center console
y Inside each front fender
y Steering wheel and column and nearby areas
y Top of the dashboard on front passenger’s
side and nearby areas
y Inside each center pillar
In the event that the SRS airbag is deployed, re-
placement of the system should be performed only by an authorized SUBARU dealer. When the
components of the SRS airbag system are re-
placed, use only genuine SUBARU parts.
To ensure their long-term reliability, the SRS airbags
must be inspected by a SUBARU dealer ten years af-
ter the date of manufacture, which is shown on the cer-
tification label attached to the driver’s door.
NOTE
In the following cases, co ntact your SUBARU deal-
er as soon as possible. y The front part of the vehicle was involved in an
accident in which the SRS frontal airbags did not deploy.y
The pad section of the steering wheel or front
passenger’s frontal airbag cover is scratched,
cracked, or otherwise damaged. „ Precautions against vehicle modifica- tion
yTo avoid accidental activation of the system
or rendering the system inoperative, which may
result in serious injury, no modifications
should be made to any components or wiring of
the SRS airbag system.
This includes following modifications:
yInstallation of cust om steering wheels
y Attachment of addition al trim materials to
the dashboardy Installation of additi onal electrical/elec-
tronic equipment such as a mobile two-way
radio on or near the SRS airbag system com-
ponents and/or wiring is not advisable. This
could interfere with proper operation of the
SRS airbag system.
