&SRS airbag system servicing
WARNING
. When discarding an airbag mod-
ule or scrapping the entire vehi-
cle damaged by a collision, con-
sult your SUBARU dealer.
. 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
If you need service or repair in areas
listed in the following, have an
authorized 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
areas
. Each front seat and nearby area
. Inside each center pillar
. In each roof side (from the front
pillar to a point over the rear seat)
. Between the rear seat cushion
and rear wheel house on each side
. Under the rear center seat
In the event that the SRS airbag is
deployed, replacement of the system
should be performed only by an author-
ized SUBARU dealer. When the compo-
nents of the SRS airbag system are
replaced, use only genuine SUBARU parts.
NOTE
In the following cases, contact your
SUBARU dealer as soon as possible. . The front part of the vehicle was
involved in an accident in which the

four transmitter codes into the system. If
you have only one current transmitter,
program it four times. If you have two
current transmitters, program each one
twice. If you have three current transmit-
ters, program two of them once and the
third one twice. This process will leave
only current transmitter codes in thesystem’s memory.
NOTE
Make sure no one else is operating
their keyless entry system within range
of your vehicle when programming
transmitters. If someone else were to
operate their remote transmitter while
you are programming your transmit-
ters, it is possible that their transmitter
code will be programmed into your
system, allowing them unauthorized
access to your vehicle. Alarm system
The alarm 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 yourvehicle.
The system can be armed and disarmed
with the remote transmitter.
The system does not operate when the
key is inserted into the ignition switch.
Your vehicle
’s alarm system has been set
for activation at the time of shipment from
the factory. You can set the system for
deactivation yourself or have it done by
your SUBARU dealer. & System alarm operation
The alarm system will give the following
alarms when triggered: . The vehicle ’s horn will sound and the
turn signal lights will flash for 30 seconds.. If any door (or the rear gate/trunk lid)
remains open after the 30-second period,
the horn will continue to sound for a
maximum of 3 minutes. If the door (or
the rear gate/trunk lid) is closed while the
horn is sounding, the horn will stop
sounding with a delay of up to 30 seconds. The alarm is triggered by: .
Opening a door, the rear gate or trunk
lid. Physical impact to the vehicle, such as
forced entry (only vehicles with shock
sensors (dealer option)) & Activating and deactivating
the alarm system
To change the setting of your vehicle ’s
alarm system for activation or deactiva-
tion, do the following.
1. Disarm the alarm system (refer to “ Disarming the system ”in this section).
2. Sit in the driver ’s seat and shut all
doors (and the rear gate if your vehicle is a
Station wagon).
3. Turn the ignition switch to the “ON ”
position.
4. Hold down the UNLOCK side of the driver ’s power door locking switch, open
the driver ’s door within the following 1
second, and wait 10 seconds without
releasing the switch. The setting will then
be changed as follows:
If the system was previously activated:

2. Turn the ignition switch from “ON ”to
“ LOCK ”position and remove the key from
the ignition switch.
3. Open the doors and get out of the vehicle.4. Before closing the doors, lock all doors
with the inside door lock levers.
5. Close the doors. The system will
automatically 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
locking switch is used to lock the vehicle,
arming will take place immediately regard-
less 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.
Also, the number of flashes indicates the
location of unauthorized intrusion or the
severity 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 (Station
wagon) was opened: 5 times
When the trunk (Sedan) was opened:
4 times
Whenastrongimpactormultiple
impacts were sensed: twice (only
vehicles with shock sensors (dealeroption))
When a light impact was sensed: once
(only vehicles with shock sensors
(dealer option))
& Shock sensors (dealer op- tion)
The shock sensors trigger the alarm
system 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 impact is weak, but it warns of Keys and doors

a strong impact or multiple impacts by
sounding the horn and flashing the turn
signal lights, both lasting approximately 30seconds.
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 break-
ing in, and cannot sense an impact that
does not cause vibration (such as
breaking the glass using a rescuehammer).. The shock sensors may sense vi-
bration like those shown in the follow-
ing and trigger the alarm system.
Select the settings of the alarm system
and shock sensors appropriately de-
pending on where you usually park
your vehicle.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 pre-
ference by your SUBARU dealer. Child safety locks
WARNING
Always use the child safety lock
whenever a child rides in the rear
seat. Serious injury could result if a
child accidentally opened the door
and fell out.
Each rear door has a child safety lock that
prevents the doors from being opened
even if the inside door handle is pulled.
When the child safety lock lever is in the
lock position, the door cannot be opened
from inside regardless of the position of
the inner door handle lock lever. The door
can only be opened from the outside. Windows &
Power windows
WARNING
To avoid serious personal injury
caused by entrapment, you must
do the following. . When operating the power win-
dows, be extremely careful to
prevent anyone ’s fingers, arms,
neck or head from being caught
in the window.
. Always lock the passengers ’win-
dows using the lock switch when
children are riding in the vehicle.
. Before leaving the vehicle, al-
ways remove the key from the
ignition switch for safety and
never allow an unattended child
to remain in the vehicle. Failure
to follow this procedure could
result in injury to a child operat-
ing the power window.
The power windows operate only when
the ignition switch is in the “ON ”position.

properly. If there is no problem and all tires
are properly inflated, the light will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pres-
sure label, you should determine the
proper inflation pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illuminates
a low tire pressure telltale when one or
more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver ’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the level to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction,
the telltale will flash for approximately one
minute and then remain continuously
illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of re-
placement or alternate tires or wheels on
the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate stea-
dily after blinking for approximately one
minute, have the system inspected by
your nearest SUBARU dealer as soon aspossible.WARNING
If this light does not come on briefly
after the ignition switch is turned ON
or the light illuminates steadily after
blinking for approximately one min-
ute, you should have your Tire
Pressure Monitoring System
checked at a SUBARU dealer as
soon as possible.
If this light comes on while driving,
never brake suddenly and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
If this light still comes on while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, replace it with a spare tire
as soon as possible.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/transmitter
being transferred, the Low tire pres-
sure warning light will illuminates
steadily after blinking for approxi-
mately one minute. This indicates Instruments and controls
3-33

3-34Instruments and controls
the TPMS is unable to monitor all
four road wheels. Contact your
SUBARU dealer as soon as possible
for tire and sensor replacement and/
or system resetting. If the light
illuminates steadily after blinking
for approximately one minute,
promptly contact a SUBARU dealer
to have the system inspected.
CAUTION
The tire pressure monitoring system
is NOT a substitute for manually
checking tire pressure. The tire
pressure should be checked peri-
odically (at least monthly) using a
tire gauge. After any change to tire
pressure(s), the tire pressure mon-
itoring system will not re-check tire
inflation pressures until the vehicle
is first driven more than 20 mph (32
km/h). After adjusting the tire pres-
sures, increase the vehicle speed to
at least 20 mph (32 km/h) to start the
TPMS re-checking of the tire infla-
tion pressures. If the tire pressures
are now above the severe low
pressure threshold, the low tire
pressure warning light should go
off a few minutes later. Therefore, be
sure to install the specified size for the front and rear tires.
& 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. . The warning light does not come
on when the ignition switch is
turned to the “ON ”position.
. The warning light comes on when
the ignition switch is turned tothe “ON ”position, but it does not
go out even when the vehicle
speed exceeds approximately 8
mph (12 km/h).
. The warning light comes on dur-
ing driving. If any of these conditions occur,
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer.
The ABS warning light comes on together
with the brake system warning light if the
EBD system becomes faulty. For further
details of the EBD system fault warning,
refer to “Brake system warning light ”.
NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal. . The warning light comes on right
after the engine is started but goes out
immediately, remaining off.. The warning light remains on after
the engine has been started, but it goes
out when the vehicle speed reaches
approximately 8 mph (12 km/h).. The warning light comes on during
driving, but it goes out immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.

CAUTION
. Do not use sharp instruments or
window cleaner containing abra-
sives to clean the inner surface
of the rear window. They may
damage the conductors printed
on the window.
. To prevent the battery from being
discharged, do not operate the
defogger continuously for any
longer than necessary.
NOTE
If your vehicle is equipped with the
outside mirror defogger, the outside
mirror defogger operates while the rear
window defogger is operating. 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
position. Pull the tab at the bottom of the
mirror toward you for the night position.
Push it away for the day position. The
night position reduces glare from head-lights. &

2) Auto dimming indicator
3) Photosensor
4) Right button
The auto-dimming mirror/compass has an
anti-glare feature which automatically re-
duces glare coming from headlights of
vehicles behind you. It also contains a
built-in compass. . By pressing and releasing the left
button, the automatic dimming function is
toggled on or off. When the automatic
dimming function is on, the auto dimming
indicator light (green) located to the right
of the button will illuminate. . By pressing and releasing the right Instruments and controls

button, the compass 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 surface turns bright if the
transmission is shifted into reverse. This
is to ensure good rearward visibility duringreversing. ! 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. !
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
seconds then release, 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 (approxi-
mately two or three circles). The compass
is now calibrated.
5. Further calibration may be necessary
should outside 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 recali-
brate the mirror. !
Compass zone adjustment
1. The zone setting is factory preset to
Zone 8. Refer to the “Compass calibration
zone ”map 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
correct zone setting for your location isdisplayed.
4. Releasing the button for 3 seconds will
exit the zone setting mode.
