6. Push the front side (“LOCK ”side) of
the power door locking switch to set the
door locks.
7. Close the door. An electronic chirp will
sound once, the turn signal lights will flash
once and the security indicator light will
start flashing rapidly. After rapid flashing
for 30 seconds (standby time), the indi-
cator lights will then flash slowly (twice
approximately every 2 seconds), indicat-
ing that the system has been armed forsurveillance. NOTE . The system can be armed even if the
engine hood and/or the windows are
opened. Always make sure that they
are fully closed before arming thesystem. .
The 30-second standby time can be
eliminated if you prefer. Have it per-
formed by your SUBARU dealer.. If your vehicle is a 4-door and you
unlock the trunk using the remotetransmitter ’s “
”button with the
alarm system armed, the system will
be temporarily placed in a standby
state. The system will go back to the
surveillance state upon locking thetrunk.. The system is in the standby mode
for a 30-second period after locking the
doors with the remote transmitter. The
security indicator light will flash at
short intervals during this period. . If any of the following actions are
done during the standby period, the
system will not switch to the surveil-
lance state.
–Doors are unlocked using the
remote transmitter. – Any door (including the rear gate
of a 5-door or the trunk of a 4-door)
is opened. – Ignition switch is turned to the
“ ON ”position.
& Disarming the system
Briefly press the “
”button (for less than
2 seconds) on the remote transmitter. The driver ’s door will unlock, an electronic chirp will sound twice, the turn signal
lights will flash twice. The flashing of the
security indicator light will then change
slowly (once approximately every 3 sec-
onds from twice approximately every 2
seconds), indicating that the alarm system
has been disarmed. NOTE
After disarming the alarm system,
briefly press the
“
”button a second
time within 5 seconds to unlock all
other doors and the rear gate (5-door). ! Emergency disarming
If you cannot disarm the system using the

tinue to flash once every 3 seconds
indicating that the system is in the valetmode.
To exit valet mode, change the setting of
your vehicle ’s alarm system for activation
mode. Refer to “Activating and deactivat-
ing the alarm system ”F 2-15.
& Passive arming
When passive arming mode has been
programmed by the dealer, arming of the
system is automatically accomplished
without using the remote transmitter. Note
that in this mode, DOORS MUST BE
MANUALLY LOCKED. ! To enter the passive mode
If you wish to program the passive arming
mode, have it done by your SUBARU
dealer. !
Arming the system
CAUTION
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 in-
dicated in step 4 below or with the
key once they have been closed.
Failure to lock the doors manually
will result in a higher security risk.
1. Turn the ignition switch to the “ON ”
position.
1) ON
2) LOCK
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 1 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 (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

&Temperature gauge
1) Normal operating range
The temperature gauge shows engine
coolant temperature when the ignition
switch is in the “ON ”position.
The coolant temperature will vary in
accordance with the outside temperature
and driving conditions.
We recommend that you drive moderately
until the pointer of the temperature gauge
reaches near the middle of the range.
Engine operation is optimum with the
engine coolant at this temperature range
and high revving operation when the
engine is not warmed up enough should
be avoided.
CAUTION
If the pointer exceeds the normal
operating range, safely stop the
vehicle as soon as possible.
Refer to “Engine overheating ”F9-

The CHECK ENGINE warning light may
stop blinking and illuminate steadily after
several driving trips. You should have your
vehicle checked by an authorized
SUBARU dealer immediately. &Charge warning light
If this light illuminates when the engine is
running, it may indicate that the charging
system is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the alternator belt. If the belt is
loose, broken or if the belt is in good
condition but the light remains illuminated,
contact your nearest SUBARU dealer
immediately. &Oil pressure warning light
If this light illuminates when the engine is
running, it may indicate that the engine oil
pressure is low and the lubricating system
is not working properly.
If the light illuminates while driving or does
not turn off after the engine starts, stop the
engine at the first safe opportunity and
check the engine oil level. If the oil level is
low, add oil immediately. If the engine oil is
at the proper level but the light remains illuminated, contact your nearest
SUBARU dealer immediately.
For details about checking the engine oil
level or adding the engine oil, refer to“

nated. This may cause serious en-
gine damage.
& Rear differential oil
temperature warning
light (STI)
CAUTION
Reduce vehicle speed and park the
vehicle in a safe place as soon as
possible if the R.DIFF TEMP light
illuminates. Continued driving with
this light illuminated can damage
the rear differential and other parts
of the powertrain.
If this light illuminates when the engine is
running, it may indicate that the rear
differential oil temperature is too hot.
At this time, the driver ’s control center
differential will automatically cancel the current torque-distribution ratio setting and
adopt its minimum ratio.
If the light illuminates while driving, reduce
vehicle speed and stop the vehicle at the
nearest safe place. Park the vehicle for
several minutes. After the light turns off,
you can start driving.
If the light does not turn off, contact the
nearest SUBARU dealer for service.
NOTE . If the tire pressures are not correct
and/or the tires are not all the same
size and brand, the rear differential will
be heavily loaded when the vehicle is
driven, resulting in an abnormally high
oil temperature.. The rear differential oil will deterio-
rate if its temperature increases en-
ough for the rear differential oil tem-
perature warning light to illuminate. It is
advisable to have the rear differential
oil replaced as soon as possible. & Low tire pressure
warning light (U.S.-spec. models)
When the ignition switch is turned to the “ON ”position, the low tire pressure warn-
ing light will illuminate for approximately 2
seconds to check that the tire pressure
