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 sound the following
alarms when triggered. . The vehicle ’s horn will sound for 30
seconds.. The turn signal lights will flash for 30
seconds.
If any of the doors 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 any of the doors, the rear gate
or trunk lid. Physical impact to the vehicle, such as
forced entry (only models with shock
sensors (dealer option))
NOTE
The alarm system can be set to trigger
the illumination of the following interiorlights. . Dome light (illuminates only when
the dome light switch is in the “DOOR ”
position) . Map lights (models with moonroof)
The notifications regarding the dome
light and the map lights are deactivated
as the factory setting. A SUBARU
dealer can activate the system. Contact
your SUBARU dealer for details. & 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 ”F 2-17.
2. Sit in the driver ’s seat and shut all
doors (and the rear gate if your vehicle is a 5-door).
3. Turn the ignition switch to the “ON ”
position.
4. Hold down the REAR (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:
The odometer/trip meter screen displays “ AL oF ”and the horn sounds twice,
indicating that the system is now deacti-vated.
If the system was previously deacti- vated:
The odometer/trip meter screen displays “ AL on ”and the horn sounds once,
indicating that the system is now acti-vated.
NOTE
You may have the above setting
change done by your SUBARU dealer. Keys and doors

!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 (5-door) was
opened: 5 times. When a door or the trunk (4-door) was
opened: 4 times. When the ignition switch was turned to
the “ON ”position: 3 times
. When a strong impact or multiple
impacts were sensed: twice (only models
with shock sensors (dealer option)) . When a light impact was sensed: once
(only models 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 the flashing. &
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 rescue hammer). . The shock sensors may sense vi-
bration as indicated in the following
examples 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. Examples:
–Vibration from a construction site
– Vibration in a multistory car park
– Vibration from trains
. You can have the sensitivity of the
shock sensors adjusted to your pre-
ference by your SUBARU dealer. Keys and doors

monitoring system (TPMS) is functioning
properly. If there is no problem and all tires
are properly inflated, the light will turn off.
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 tire inflation pressure for thosetires.)
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 as
possible.
WARNING
If this light does not illuminate
briefly after the ignition switch is
turned ON or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
If this light illuminates 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 illuminates 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 illuminate Instruments and controls
3-17

3-18Instruments and controls
steadily after blinking for approxi-
mately one minute. This indicates
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 min-
ute, 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 turn off a few minutes later. Therefore, be
sure to install the specified size for
the front and rear tires.
& ABS warning light
CAUTION
. If any of the following conditions
occur, we recommend that you
have the ABS system repaired at
the first available opportunity by
your SUBARU dealer. – The warning light does not
illuminate when the ignition
switch is turned to the “ON ”
position.
– The warning light illuminates
when the ignition switch is
turned to the “ON ”position,
but it does not turn off even
when the vehicle speed ex-
ceeds approximately 8 mph
(12 km/h).
– The warning light illuminates
during driving.
. When the warning light is on (and
the brake system warning light is
off), the ABS function shuts
down. However, the conventional
brake system continues to oper- ate normally.
With a vehicle equipped with an EBD
system, the ABS warning light illuminates
together with the brake system warning
light if the EBD system malfunctions. For
further details of the EBD system mal-
function warning, refer to “Electronic
Brake Force Distribution (EBD) systemwarning ”F 3-19.
NOTE
If the warning light behavior is as
described in the following conditions,
the ABS system may be considerednormal. . The warning light illuminates right
after the engine is started but turns off
immediately, remaining off.. The warning light remains illumi-
nated after the engine has been started,
but it turns off when the vehicle speed
reaches approximately 8 mph (12km/h).. The warning light illuminates during
driving, but it turns off immediately and
remains off.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may illumi-
nate. This is due to the low battery voltage
and does not indicate a malfunction.

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/com-
pass (if equipped)
1) Auto dimming indicator
2) Left (mirror) button
3) Photosensor
4) Right (compass) button
5) Compass display
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 on the left
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 upper right corner 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 Instruments and controls
