Seat, seatbelt and SRS airbags
– CONTINUED –
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 system (if equipped)
The security system helps to protect your vehicle and
valuables from theft. The horn sounds and the turn
signal lights flash if someone attempts to break into
your vehicle. The starter motor is also interrupted to
prevent starting the vehicle without a key.
The system can be armed and disarmed with the re-
mote transmitter.
The system does not operate when the key is inserted
into the ignition switch. „System operation
The security system will give the following alarm indi-
cations when triggered: y The turn signal lights will flash and the horn will
sound intermittently. In addition, the starter motor will
not operate. y The alarm automatically resets after 30 seconds;
however, the alarm will reactivate if the vehicle is tam-
pered with again. The alarm will continue for six times
if any sensor continues to be activated.
The alarm is triggered by: y Opening a door, the rear gate or trunk lid.
y Application of physical shock to the vehicle (e.g. forced entry). Note that there are two alarm levels for
shock: warning and alarm. In warning mode, the alarm
detects lower level vibrations and triggers 2 warning
chirps on the horn and two flashes on the lights as a
deterrent to would be vandals. In alarm mode, higher
levels of shock are detected and the system will go into full alarm. y
Ignition switch being turned on while in armed state.
NOTE
With the valet mode selected, the security system
does not operate when the remote transmitter is
used for locking and unlocking. The security indi-
cator light in the combination meter flashes twice
per second to show that the valet mode is select-
ed. For details, refer to “Valet mode” in this sec- tion. „ Arming the system
T To arm the system using remote transmitter
1. Close all windows.
2. Remove the key from the ignition switch.
3. Open the doors and get out of the vehicle.
4. Make sure that the engine hood (and the trunk lid)
are locked.
5. Close all doors (and the rear gate on the Wagon).

Keys and doors
In passive mode, the system will automatically
activate the alarm but WILL NOT automatically
lock the doors. In order to lock the doors you
must either lock them as indicated in step 4
above or with the key once they have been
closed. Failure to lock the doors manually will
result in a higher security risk.
T Disarming the system
To disarm the system, briefly press the “ ” button
on the transmitter. V Tripped sensor identification (all models ex- cept WRX-STi)
If an electronic chirp sounds four times and the turn
signal lights flash four times when you disarm the sys-
tem, this indicates that the alarm was triggered. The
number of times the indicator light flashes indicates
what sensor caused the alarm condition.
To enter identification mode:
1. Open the driver’s door and leave it open.
2. Turn the ignition switch to the “ON” position twice. (“LOCK” “ON” “LOCK” “ON” “LOCK”)
3. The indicator light will start flashing. The indicator light provides the following indications.
Flashing once:
Any door, the rear gate or the trunk lid
has been opened.
Flashing three times: The impact sensor in the sys-
tem’s unit has been activated. This may indicate that
your vehicle has been shocked or tampered with by
some outside force and/or unauthorized person.
Flashing four times: The ignition switch has been
turned on or the battery has been disconnected.
NOTE
The battery must be reconnected before the indi-
cator light will flash.
To exit this mode, close the door and turn the ignition
switch to the “ON” position.

Auto-dimming mirror/compass (if equipped)
1) Left button
2) Auto dimming indicator
3) Photosensor
4) Right button
The inside electronic compass mirror has an anti-glare
feature which automatically reduces glare coming
from headlights of vehicles behind you. It also con-
tains a built-in compass. y By pressing and releasing the left button, the auto-
matic dimming function is toggled on or off. When the
automatic dimming function is on, the auto dimming in-
dicator light (green) located to the right of the button will illuminate.y
By pressing and releasing the right button, the com-
pass display is toggled on or off. When the compass is
on, an illuminated compass reading will appear in the
lower part of the mirror.
Even with the mirror in anti-glare mode, the mirror sur-
face turns bright if the transmission is shifted into re-
verse. This is to ensure good rearward visibility during
reversing. V Photosensors
The mirror has a photosensor attached on both the
front and back sides. If the glare from the headlights of
vehicles behind you strikes the mirror, these sensors

detect it and make the reflection surface of the mirror
dimmer to help prevent you from being blinded. For
this reason, use care not to cover the sensors with
stickers, or other similar items. Periodically wipe the
sensors clean using a piece of dry soft cotton cloth or
an applicator. VCompass calibration
1. For optimum calibration, switch off all nonessential
electrical accessories (rear window defogger, heater/
air conditioning system, spotlight, etc.) and ensure all
doors are shut.
2. Drive to an open, level area away from large metal-
lic objects or structures and make certain the ignition
switch is in the “ON” position.
3. Press and hold the left button for 3 seconds then re-
lease, and the compass will enter the calibration
mode. “CAL” and direction will be displayed.
4. Drive slowly in a circle until “CAL” disappears from
the display (about two or three circles). The compass
is now calibrated.
5. Further calibration may be necessary should out-
side. Influences cause the mirror to read inaccurately.
You will know that this has occurred if your compass
begins to read in only limited directions. Should you
encounter this situation, return to step one of the
above procedure and recalibrate the mirror. V
Compass zone adjustment
Compass calibration zones
1. The zone setting is factory preset to Zone 8. Refer
to the “Compass calibration zone” map shown above
or one attached to the end of this manual to verify that
the compass zone setting is correct for your geograph-
ical location.
2. Press and hold the right button for 3 seconds then
release, and the word “ZONE” will briefly appear and
then the zone number will be displayed.
3. Press the right hand button repeatedly to cycle the

Temperature sensors
1) Interior air temperature sensor
2) Solar sensor
The automatic climate control system employs several
sensors. These sensors are delicate. If they are not
treated properly and become damaged, the system
may not be able to control the interior temperature cor-
rectly. To avoid damaging the sensors, observe the
following precautions:
– Do not subject the sensors to impact.
– Keep water away from the sensors.
– Do not cover the sensors. The sensors are located as follows:
– Solar sensor: beside windshield defroster grille
– Interior air temperature sensor: beside the fan
speed control dial
– Outside temperature sensor: behind front grille.

Appearance care
– CONTINUED –
flush the suspension and axle parts, as they are par-
ticularly prone to mud and sand buildup. Do not use a
sharp-edged tool to remove caked mud.
NOTE
Be careful not to damage brake hoses, sensor har-
nesses, and other parts when washing suspen-
sion components. TUsing a warm water washer
y Keep a good distance of 12 in (30 cm) or more be-
tween the washer nozzle and the vehicle. y Do not wash the same area continuously.
y If a stain will not come out easily, wash by hand.
Some warm water washers are of the high tempera-
ture, high pressure type, and they can damage or de-
form the resin parts such as mouldings, or cause wa-
ter to leak into the vehicle. „ Waxing and polishing
Always wash and dry the vehicle before waxing and
polishing.
Use a good quality polish and wax and apply them ac-
cording to the manufacturer’s instructions. Wax or pol-
ish when the painted surface is cool.
Be sure to polish and wax the chrome trim, as well as
the painted surfaces. Loss of wax on a painted surface leads to loss of the original luster and also quickens
the deterioration of the surface. It is recommended
that a coat of wax be applied at least once a month, or
whenever the surface no longer repels water.
If the appearance of the paint has diminished to the
point where the luster or tone cannot be restored,
lightly polish the surface with a fine-grained com-
pound. Never polish just the affected area, but include
the surrounding area as well. Always polish in only
one direction. A No. 2000 grain compound is recom-
mended. Never use a coarse-grained compound.
Coarser grained compounds have a smaller grain-size
number and could damage the paint. After polishing
with a compound, coat with wax to restore the original
luster. Frequent polishing with a compound or an in-
correct polishing technique will result in removing the
paint layer and exposing the undercoat. When in
doubt, it is always best to contact your SUBARU deal-
er or an auto paint specialist.
NOTE
Be careful not to block the windshield washer noz-
zles with wax when waxing the vehicle. „
Cleaning aluminum wheels
