SRS airbag system servicing
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
to your nearest SUBARU dealer to
have the system checked. Unless
checked and properly repaired, the
seatbelt pretensioners and/or SRS
airbag will not operate properly in
the event of a collision, which may
increase the risk of injury.
Flashing or flickering of the warn-
ing light
No illumination of the warning
light when the ignition switch is
first turned to the “ON ” position
Continuous illumination of the
warning light
Illumination of the warning light
while driving
When discarding an airbag mod-
ule or scrapping the entire vehicle
damaged by a collision, consult
your SUBARU dealer.
The SRS airbag has no user-ser-
viceable parts. Do not use electri-
cal 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 discon-
necting the system ’s wiring could
result in accidental inflation of the
SRS airbag or could make the sys-
tem inoperative, which may result
in serious injury. The wiring har-
nesses of the SRS airbag system
are covered with yellow insulation
and system connectors are yellow
for easy identification.

1-58 Seat, seatbelt and SRS airbags
In the event that the SRS airbag is de-
ployed, replacement of the system
should be performed only by an autho-
rized SUBARU dealer. When the com-
ponents of the SRS airbag system are
replaced, use only genuine SUBARU
parts.
To ensure their long-term reliability, the
SRS airbags must be inspected by a
SUBARU dealer ten years after the date
of manufacture, which is shown on the
certification plate attached to the driver ’s door jamb.
NOTE
In the following cases, contact your
SUBARU dealer as soon as possible.
The front part of the vehicle was in-
volved in an accident in which only the
driver ’s SRS frontal airbag or both driv-
er ’s and front passenger ’s SRS frontal
airbags did not deploy.
The pad section of the steering
wheel or front passenger ’s frontal air-
bag 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.
Either center pillar or a nearby area
of the vehicle was involved in an acci-
dent in which the SRS side airbag did
not deploy.
The fabric or leather of either front
seatback is cut, frayed, or otherwise
damaged.
Precautions against vehicle
modification
If you need service or repair in areas
listed in the following, have an au-
thorized SUBARU dealer perform
the work. The SRS airbag control
module, impact sensors and airbag
modules are stored in these areas.
Under the center console
Inside each front fender
Steering wheel and column and
nearby areas
Top of the dashboard on front
passenger ’s side and nearby ar-
eas
Each front seat and nearby area
Inside each center pillar
To avoid accidental activation of
the system or rendering the sys-
tem inoperative, which may result
in serious injury, no modifications
should be made to any compo-
nents or wiring of the SRS airbag
system.
This includes following modifica-
tions:
Installation of custom steering
wheels
Attachment of additional trim
materials to the dashboard
Installation of custom seats

4. Before closing the doors, lock all doors
with the inside door lock levers.
5. Close the doors. The system will auto-
matically arm after one minute.
In the passive mode, the system can also
be armed with the remote transmitter or
with the power door locking switches. If
the remote transmitter or power door lock-
ing switch is used to lock the vehicle, arm-
ing will take place immediately regardless
of whether or not the passive mode has
been selected.
Disarming the system
To disarm the system, briefly press the
“ ” button on the transmitter.
Tripped sensor identification
The security indicator light flashes when
the alarm system has been triggered. Al-
so, the number of flashes indicates the lo-
cation of unauthorized intrusion or the se-
verity of impact on the vehicle.
When the ignition switch is turned to the
“ ON ” position, the indicator light will light
for 1 second and then flash as follows: When a door or rear gate (Wagon) or
the trunk (Sedan) was opened: 5 times
When the ignition switch was turned to
the “ON ” position: 3 times
When a strong impact or multiple im-
pacts were sensed: twice (only vehicles
with shock sensors (dealer option))
When a light impact was sensed: once
(only vehicles with shock sensors (deal-
er option))
NOTE
Any of the above indicator light flash-
ings will recur each time the ignition
switch is turned to the “ON ” position.
Rearming the alarm system cancels
the flashing.
Shock sensors (dealer op-
tion)
The shock sensors trigger the alarm sys-
tem when they sense impacts applied to the vehicle and when any of their electric
wires is cut. The alarm system causes the
horn to sound and the turn signal lights to
flash for a short time when the sensed im-
pact is weak, but it warns of a strong im-
pact or multiple impacts by sounding the
horn and flashing the turn signal lights,
both lasting approximately 30 seconds.
If you desire, your SUBARU dealer can
connect them and set them for activation
or deactivation.
NOTE
The shock sensors are not always
able to sense impacts caused by
breaking in, and cannot sense an im-
pact that does not cause vibration
(such as breaking the glass using a
rescue hammer).
The shock sensors may sense vibra-
tion like those shown in the following
and trigger the alarm system. Select
the settings of the alarm system and
shock sensors appropriately depend-
ing on where you usually park your ve-
hicle.
Example:
Vibration from construction site
Vibration in multistory car park
Vibration from trains
You can have the sensitivity of the
shock sensors adjusted to your prefer-
ence by your SUBARU dealer.

3-32 Instruments and controls
Mirrors
Always check that the inside and outside
mirrors are properly adjusted before you
start driving.
Inside mirror
The inside mirror has a day and night po-
sition. Pull the tab at the bottom of the mir-
ror toward you for the night position. Push
it away for the day position. The night po-
sition reduces glare from headlights.
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 contains a
built-in compass.
By pressing and releasing the left but-
ton, the automatic dimming function is tog-
gled on or off. When the automatic dim-
ming function is on, the auto dimming indi-
cator light (green) located to the right of
the button will illuminate.
By pressing and releasing the right but- ton, the compass display is toggled on or
off. When the compass is on, an illuminat-
ed compass reading will appear in the
lower part of the mirror.
Even with the mirror in anti-glare mode,
the mirror surface turns bright if the trans-
mission is shifted into reverse. This is to
ensure good rearward visibility during re-
versing.
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 mir-
ror 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 sen-
sors clean using a piece of dry soft cotton
cloth or an applicator.
Compass 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 metallic objects or structures and
make certain the ignition switch is in the “ ON ” position.
3. Press and hold the left button for 3 sec-
onds then release, and the compass will
enter the calibration mode. “CAL ” and di-
rection will be displayed.
4. Drive slowly in a circle until “CAL ” dis-
appears from the display (approximately
two or three circles). The compass is now
calibrated.
5. Further calibration may be necessary
should outside. Influences cause the mir-
ror 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 recali-
brate the mirror.
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
geographical 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 display through all possible
zone settings. Stop cycling when the cor-
rect zone setting for your location is dis-
played.
4. Releasing the button for 3 seconds will exit the zone setting mode.

Objects look smaller in a convex
mirror and farther away than when
viewed in a flat mirror. Do not use
the convex mirror to judge the dis-
tance of vehicles behind you when
changing lanes. Use the inside mir-
ror (or glance backwards) to deter-
mine the actual size and distance of
objects that you view in convex mir-
ror.

OFF position when the interior has cooled
to a comfortable temperature and the road
is no longer dusty. The indicator light will
go off.
AUTO: When the air inlet selection button
is pressed for at least one second, the in-
dicator flashes twice. The air inlet control
is then adjusted automatically in accor-
dance with the air temperature inside and
outside the passenger compartment, the
intensity of sunlight, and other factors.
Pressing the air inlet selection button can-
cels the “AUTO ” mode. SUBARU recom-
mends using the AUTO position.Air conditioner button
The button ’s positions and their functions
are as follows:
ON: The air conditioner operates while the
fan is running.
Push the button to select this position. The
indicator light will illuminate.
OFF: The air conditioner does not operate.
Push the button a second time to select
this position. The indicator light will go off.

least one second, the indicator flashes
twice. The air conditioner compressor op-
eration is then adjusted automatically in
accordance with the air temperature in-
side and outside the passenger compart-
ment, the intensity of sunlight, and other
factors. Pressing the button cancels the “
AUTO ” mode. SUBARU recommends us-
ing the AUTO position.
NOTE
The air conditioner ’s compressor does
not operate with an outside tempera-
ture of 32 F (0 C) or lower.
Temperature sensors
1) Interior air temperature sensor
2) Solar sensor
The automatic climate control system em-
ploys 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 tempera-
ture correctly. To avoid damaging the sen-
sors, observe the following precautions:
Continued operation in the ON posi-
tion may fog up the windows.
Switch to the OFF position as soon
as the outside dusty condition
clears.
