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 your
vehicle. The starter motor is also inter-
rupted to prevent starting the vehicle
without a key.
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 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.
In addition, the starter motor will notoperate. . 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 (see “Dis-
arming 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 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:

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 (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
impacts were sensed: twice (only
vehicles with shock sensors (dealeroption))
When a light impact was sensed: once
(only vehicles with shock sensors
(dealer 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 theflashing. &
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 are 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
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. Keys and doors

. You can have the sensitivity of the
shock sensors adjusted to your pre-
ference by your SUBARU dealer. Child safety locks
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.
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. 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.

3-32Instruments 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
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. !
Auto-dimming mirror/compass (ifequipped)
1) Left button
2) Auto dimming indicator
3) Photosensor
4) Right button
The auto-dimming 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
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
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

using the AUTO position.
NOTE
The air conditioner ’s compressor does
not operate with an outside tempera-
ture of 32 8F(0 8C) or lower.
& 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 sys-
tem may not be able to control the interior
temperature correctly. To avoid damaging
the sensors, observe the following pre- cautions: –
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 defros-
ter grille– Interior air temperature sensor: beside
the fan speed control dial– Outside temperature sensor: behind
front grille. Operating tips for heater and
air conditioner &
Cleaning ventilation grille
Always keep the front ventilator inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept clean
because cooling performance is impaired
by any accumulation of insects and leaves
on the condenser. &Efficient cooling after parking
in direct sunlight
After parking in direct sunlight, drive with
the windows open for a few minutes to

dealer.
The driver ’s control center differential
allows you to freely change the degree
of limitation of the differential action
(limited slip differential (LSD) torque) of
your vehicle ’s center differential.
By using the center differential control dial,
you can set an initial LSD torque to match
the road surface conditions, driving con-
ditions and your driving style.
1) LSD torque
2) Traction torque
A) Initial LSD torque (adjustable)
B) Mechanical LSD torque &
Auto mode
In the auto mode, the system estimates
the driving and road conditions using
signals from the wheel speed sensor,
throttle position sensor, steering angle
sensor and brake switch, etc. According
to the result, it electronically and auto-
matically controls the degree of limitation
of the differential action (LSD torque) to
optimize the differential action of the
center differential. When the ignition
switch is turned ON, the “AUTO ”indicator
light in the combination meter comes on.
The system can be switched to a manual mode. &
Manual mode
In the manual mode, you can use the
center differential control dial to adjust the
initial LSD torque as desired. When this
mode is selected, the “AUTO ”indicator
light in the combination meter goes off. ! Manual switch
Press the “DCCD-MANU ”switch on the
center console to switch from auto mode
to manual mode. The “AUTO ”indicator
light in the combination meter will go off.
Press the switch again to go back to auto
mode. The “AUTO ”indicator light in the
combination meter will come on. Starting and operating

components may accelerate their corro- sion.
After driving off-road or on muddy or
sandy roads, wash the mud and sand off
the underbody. Carefully flush the suspen-
sion and axle parts, as they are particu-
larly 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 harnesses, and other parts
when washing suspension compo-nents. !Using a warm water washer
. Keep a good distance of 12 in (30 cm)
or more between the washer nozzle and
the vehicle. . Do not wash the same area continu-
ously.. If a stain will not come out easily, wash
by hand. Some warm water washers are
of the high temperature, high pressure
type, and they can damage or deform the
resin parts such as moldings, or cause
water 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 according to the manufac-turer
’s instructions. Wax or polish 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 recom-
mended 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 dimin-
ished to the point where the luster or tone
cannot be restored, lightly polish the
surface with a fine-grained compound.
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. Coarse-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
acompoundoranincorrectpolishing
technique will result in removing the paint
layer and exposing the undercoat. When
in doubt, it is always best to contact your
SUBARU dealer or an auto paint specia- list.
NOTE
Be careful not to block the windshield
washer nozzles with wax when waxing
the vehicle. & Cleaning aluminum wheels
. Promptly wipe the aluminum wheels
clean of any kind of grime or agent. If dirt
is left on too long, it may be difficult to
clean off. . Do not use soap containing grit to
clean the wheels. Be sure to use a neutral
cleaning agent, and later rinse thoroughly
with water. Do not clean the wheels with a
stiff brush or expose them to a high-speed
washing device. . Clean the vehicle (including the alumi-
num wheels) with water as soon as
possible when it has been splashed with
sea water, exposed to sea breezes, or
driven on roads treated with salt or otheragents. Appearance care
