1-22Seat, seatbelt and SRS airbags
CAUTION
The front sub sensors are located in
both front fenders and the SRS
airbag 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.
NOTE
If the front part of the vehicle is
damaged in an accident to the extent
that the seatbelt pretensioner does not
operate, 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.
CAUTION
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
placard attached to the driver ’s
door pillar or specified for indivi-
dual vehicle models in this Own-er ’s Manual. Child restraint systems
Infants and small children should always
be placed in an infant or child restraint
system in the rear seat while riding in the

restraint system that meets Federal Motor
Vehicle Safety Standards or Canada
Motor Vehicle Safety Standards, is com-
patible with your vehicle and is appro-
priate for the child
’s age and size. All child
restraint systems are designed to be
secured in vehicle seats by lap belts or

the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag system. Immediately take your vehi-
cle to your nearest SUBARU dealer
to have the system checked. Unless
checked and properly repaired, the

. 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 result in accidental
inflation of the SRS airbag or
could make the system inopera-
tive, which may result in serious
injury. The wiring harnesses of
the SRS airbag system are cov-
ered with yellow insulation and
system connectors are yellow for
easy identification.

CAUTION
Do not operate the engine with the
oil pressure warning light on. This
may cause serious engine damage.
& 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 the engine has started.
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
unnecessary 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 transmis-
sion control system is not working prop-
erly. Contact your nearest SUBARU deal- er for service immediately.
& Rear differential oil
temperature warning
light (WRX-STI)
CAUTION
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 thepowertrain.
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 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 en-
ough 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 ”
position and goes out after approximately
2 seconds.
This is an indication that the ABS system
is working properly.
CAUTION
If the warning light behaves as
follows, 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. Instruments and controls

heated interior. This results in quicker
cooling by the air conditioner. Keep the
windows closed during the operation of
the air conditioner for maximum cooling
efficiency. &Lubrication oil circulation in
the refrigerant circuit
Operate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil. & Checking air conditioning
system before summer sea-son
Check the air conditioner unit for refriger-
ant leaks, hose conditions and proper
operation of each spring. Have your
SUBARU dealer perform this check. & Cooling and dehumidifying in
high humidity and low tem-
perature weather conditions
Under certain weather conditions (high
relative humidity, 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 conditioningsystem. &
Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is designed
to temporarily shut off during air condi-
tioner operation whenever the accelerator
is fully depressed such as during rapid
acceleration or when driving on a steepupgrade. & Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the meth-
od 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
If your vehicle
’s air conditioning system is
equipped with an air filtration system,
replace the filter element according to
the replacement schedule shown in the
following. This schedule should be fol-
lowed to maintain the filter ’s dust collec-
tion ability. Under extremely dusty condi-
tions, 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) whichever comes first
