Seat, seatbelt and SRS airbags
– CONTINUED –
yIf the front seatbelt retractor assembly or sur-
rounding area has been damaged, contact your
SUBARU dealer as soon as possible. y When you sell your vehicle, we urge you to ex-
plain to the buyer that it has seatbelt pretension-
ers by alerting him to the contents of this section.
y To obtain maximum protection, the occu-
pants should sit in an upright position with
their seatbelts properly fastened. Refer to the “Seatbelts” section in this chapter.y Do not modify, remove or strike the front
seatbelt retractor assemblies or surrounding
area. This could result in accidental activation
of the seatbelt pretensioners or could make the
system inoperative, possibly resulting in seri-
ous injury. Seatbelt pretensioners have no
user-serviceable parts. For required servicing
of front seatbelt retractors equipped with seat-
belt pretensioners, see your nearest SUBARU
dealer.y When discarding front seatbelt retractor as-
semblies or scrapping the entire vehicle due to
collision damage or for other reasons, consult
your SUBARU dealer.
„ System monitors
A diagnostic system continually monitors the readi-
ness of the seatbelt pretensioner while the vehicle is
being driven. The seatbelt pretensioners share the
control module with the SRS airbag system. There-
fore, if any malfunction occurs in a seatbelt preten-
sioner, the SRS airbag system warning light will illumi-
nate. The SRS airbag system warning light will show
normal system operation by lighting for about 6 sec-
onds when the ignition key is turned to the “ON” posi-

The front sub sensors are located in both front
fenders and the SRS airbag control module in-
cluding 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, we recommend that you have an autho-
rized SUBARU dealer perform 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, contact 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 pretensioners. 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
front end structure. y Installation of a tire of different size and con-
struction from the tires specified on the tire
placard attached to the driver’s door jamb.

„ 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 dealer. 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 be-
low, we recommend that you have an autho-
rized SUBARU dealer perform the work. The
SRS airbag control module, impact sensors
and airbag modules are stored in these areas. yUnder 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 Each front seat and nearby area (only for ve-
hicles with SRS side airbags)
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 plate attached to the driver’s door jamb.
NOTE
In the following cases, contact 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.
In addition, if your vehicle is equipped with SRS
side airbags, contact your SUBARU dealer as
soon as possible in the following cases.y Either center pillar or a nearby area of the vehi-
cle was involved in an accident in which the SRS
side airbag did not deploy.y The fabric or leather of either front seatback is
cut, frayed, or otherwise damaged. „ Precautions against vehicle modifica- tion

„Security indicator light
The security indicator light deters potential thieves by
indicating that the vehicle is equipped with an immobi-
lizer system. It begins flashing (approximately once
every three seconds) about 60 seconds after the igni-
tion switch is turned from the “ON” position to the
“ACC” or “LOCK” position or immediately after the key
is pulled out.
If the security indicator light does not flash, the immo-
bilizer system may be faulty. If this occurs, we recom-
mend that you contact your SUBARU dealer as soon
as possible.
In case an unauthorized key is used (e.g. an imitation
key), the security indicator light comes on.
NOTE
Even if the security indicator light flashes irregu-
larly or its fuse blows (the light does not flash if its
fuse is blown), the immobilizer system will func-
tion normally. „ Key replacement
Your key number and security ID will be required if you
ever need a replacement key made. Any new key
must be registered for use with your vehicle’s immobi-
lizer system before it can be used. Up to four keys can be registered for use with one vehicle.
For security, all the keys registered with your vehicle’s
immobilizer system will have their ID codes erased
and re-registered when a new key is made. Therefore,
all of your vehicle’s keys must be presented when a
new key is registered. Any key that is not re-registered
when a new key is made cannot be used after the oth-
er keys are re-registered. For information on replace-
ment keys and on the registration of keys with your im-
mobilizer system, we recommend that you contact
your SUBARU dealer.

Instruments and controls
– CONTINUED –
If the light comes on while driving, it is unnecessary to
stop the vehicle, but avoid driving up steep grades or
in stop and go traffic. TAutomatic transmission control system warn- ing
If the light flashes after the engine starts, it may indi-cate that the automatic transmission control system is
not working properly. Contact your nearest SUBARU
dealer for service immediately. „ Rear differential oil temperature
warning light (WRX-STi)
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 differential
and other parts of the powertrain.
If this light comes on when the engine is running, it
may indicate that the rear differential oil temperature is
too hot.
At this time, the driver’s control center differential will automatically cancel the current torque-distribution ra-
tio 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 y
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 tem-
perature.y The rear differential oil will deteriorate if its tem-
perature increases enough for the rear differential
oil temperature warning light to come on. It is ad-
visable 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” position and goes out after
about two seconds.
This is an indication that the ABS system is working
properly.

Climate control
„
Cooling and dehumidifying in high hu-
midity and low temperature weather
conditions
Under certain weather conditions (high relative humid-
ity, low temperatures, etc.) a small amount of water
vapor emission from the air outlets may be noticed.
This condition is normal and does not indicate any
problem with the air conditioning system. „ Air conditioner compressor shut-off
when engine is heavily loaded
To improve acceleration and gas mileage, the air con-
ditioner compressor is designed to temporarily shut off
during air conditioner operation whenever the acceler-
ator is fully depressed such as during rapid accelera-
tion or when driving on a steep upgrade. „ Refrigerant for your climate control
system
Your air conditioner uses ozone friendly refrigerant
HFC134a. Therefore, the method of adding, changing
or checking the refrigerant is different from the method
for CFC12 (Freon). Consult your SUBARU dealer for
service. Repairs needed as a result of using the wrong
refrigerant are not covered under warranty. Air filtration system (Turbo model
only)
If your vehicle’s air conditioning system is equipped
with an air filtration system, replace the filter element
according to the replacement schedule shown below.
This schedule should be followed to maintain the fil-
ter’s dust collection ability. Under extremely dusty con-
ditions, the filter should be replaced more frequently. It
is recommended that you have your filter checked or
replaced by your SUBARU dealer. For replacement,
use only a genuine SUBARU air filter kit.
Replacement schedule:
Every 12 months or 7,500 miles (12,000 km) whichev-
er comes first
