1-20 Seat, seatbelt and SRS airbags
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 in-
volving a moderate to severe frontal colli-
sion.
The pretensioner sensor also serves as
the frontal SRS airbag sensor. If the sen-
sor detects a certain predetermined
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 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
Seatbelt pretensioners are not de-
signed to activate in minor frontal im-
pacts, in side or rear impacts or in roll-
over accidents.
The driver ’s seat and passenger ’s
seat pretensioners and frontal SRS air-
bag operate simultaneously.
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 only by an authorized
SUBARU dealer. When replacing seat-
belt retractor assemblies, use only
genuine SUBARU parts.
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.
If the front seatbelt retractor assem-
bly or surrounding area has been dam-
aged, 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 him
to the contents of this section.
100121
To obtain maximum protection,
the occupants should sit in an up-
right position with their seatbelts
properly fastened. Refer to the “ Seatbelts ” section in this chap-
ter.
Do 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.

1-22 Seat, seatbelt and SRS airbags
System servicing
NOTE
If the front part of the vehicle is dam-
aged in an accident to the extent that
the seatbelt pretensioner does not op-
erate, contact your SUBARU dealer as
soon as possible.
Precautions against vehicle
modification
Always consult your SUBARU dealer if
you want to install any accessory parts to
your vehicle.
When discarding a seatbelt retrac-
tor assembly or scrapping the en-
tire vehicle damaged by a colli-
sion, consult your SUBARU deal-
er.
Tampering with or disconnecting
the system ’s wiring could result in
accidental activation of the seat-
belt pretensioner and/or SRS air-
bag or could make the system in-
operative, which may result in se-
rious injury. The wiring harnesses
of the seatbelt pretensioner and
SRS airbag systems are covered
with yellow insulation and the
connectors of the system are yel-
low for easy identification. Do not
use electrical test equipment on
any circuit related to the seatbelt
pretensioner and SRS airbag sys-
tems. For required servicing of
the seatbelt pretensioner, see
your nearest SUBARU dealer.
The front sub sensors are located in
both front fenders and the SRS air-
bag control module including the
impact sensors is located under the
center console. If you need service
or repair in those areas or near the
front seatbelt retractors, we recom-
mend that you have an authorized
SUBARU dealer perform the work.
Do not perform any of the following
modifications. Such modifications
can interfere with proper operation
of the seatbelt pretensioners.
Attachment of any equipment
(bush bar, winches, snow plow,
skid plate, etc.) other than genu-
ine SUBARU accessory parts to
the front end.
Modification of the suspension
system or front end structure.
Installation of a tire of different
size and construction from the
tires specified on the vehicle plac-
ard attached to the driver ’s door
pillar or specified for individual
vehicle models in this Owner ’s
Manual.

When a heavy article is placed on the
seat.
When the front passenger ’s seat is occu-
pied by an adult, observe the following
precautions. Failure to do so may lessen
the load on the front passenger ’s seat, de-
activating the front passenger ’s SRS fron-
tal airbag despite the fact that the seat is
occupied by an adult.
Do not allow the rear seat occupant to
lift the front passenger ’s seat cushion us-
ing his/her feet.
Do not place any article under the front
passenger ’s seat, or squeeze any article
from behind and under the seat. This may
lift the seat cushion.
Do not squeeze any article between the
front passenger ’s seat and side trim/pillar,
door or center console box. This may lift
the seat cushion.
If the passenger ’s frontal airbag
OFF indicator illuminates and the
ON indicator extinguishes even
when the front passenger ’s seat is
occupied by an adult
This can be caused by the adult incorrect-
ly sitting in the front passenger ’s seat.
Turn the ignition switch to the “OFF ” posi-
tion. Ask the front passenger to set the
seatback to the upright position, sit up
straight in the center of the seat cushion, correctly fasten the seatbelt, position his/
her legs out forward, and adjust the seat
to the rearmost position. Turn the ignition
switch to the
“ON ” position. If the OFF in-
dicator remains illuminated while the ON
indicator remains extinguished, take the
following actions.
Turn the ignition switch to the “OFF ” po-
sition.
Ensure that there is no article, book,
shoe, or other object trapped under the
seat, at the rear of the seat, or on the side
of the seat.
Ensure that the backward-forward posi-
tion and seatback of front passenger ’s
seat are locked into place securely by
moving the seat back and forth.
Next, turn the ignition switch to the “ON ”
position and wait 6 seconds to allow the
system to complete self-checking. Follow-
ing the system check, both indicators ex-
tinguish for 2 seconds. Now, the ON indi-
cator should illuminate while the OFF indi-
cator remains extinguished.
If the OFF indicator still illuminates while
the ON indicator remains extinguished,
ask the occupant to move to the rear seat
and immediately contact your SUBARU
dealer for an inspection.

is at the proper level but the light remains
on, contact your nearest SUBARU dealer
immediately.
AT OIL TEMPerature
warning light (AT vehi-
cles)
The AT oil temperature warning light
comes on when the ignition switch is
turned to the
“ON ” position and goes out
after approximately two seconds.
If this light comes on when the engine is
running, it may indicate that the automatic
transmission fluid temperature is too hot.
If the light comes on while driving, it is un-
necessary to stop the vehicle, but avoid
driving up steep grades or in stop and go
traffic.
Automatic transmission control
system warning
If the light flashes after the engine starts,
it may indicate that the automatic trans-
mission control system is not working
properly. Contact your nearest SUBARU dealer for service immediately.
Rear differential oil tem-
perature warning light
(WRX-STI)
If this light comes on when the engine is
running, it may indicate that the rear differ-
ential oil temperature is too hot.
At this time, the driver
’s control center dif-
ferential will automatically cancel the cur-
rent torque-distribution ratio setting and
adopts its minimum ratio.
If the light comes on while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place.
Park the vehicle for several minutes. After
the light goes out, you can start driving.
If the light does not go out, contact the
nearest SUBARU dealer for service.
NOTE
If the tire pressures are not correct
and/or the tires are not all the same
size and brand, the rear differential will
be heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.
The rear differential oil will deterio-
rate if its temperature increases
enough for the rear differential oil tem-
perature warning light to come on. It is
advisable to have the rear differential
oil replaced as soon as possible.
ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ” posi-
tion and goes out after approximately two
seconds.
This is an indication that the ABS system
is working properly.
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
comes on. Continued driving with
this light on can damage the rear dif-
ferential and other parts of the pow-
ertrain.
If the warning light behaves as fol-
lows, the ABS system may not work
properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally.
