2) Submaster key (Black)
3) Valet key (Gray)
4) Key number plate
5) Security ID plate
Three types of keys are provided for your vehicle:
Master key, submaster key and valet key.
The master key and submaster key fit all
locks on your vehicle. . Ignition switch
. Driver ’s door
. Trunk lid release lever (4-door)
. Glove box
The valet key fits only the ignition switch and driver
’s door lock. You can keep the
trunk and glove box locked when you
leave your vehicle and valet key at a
parking facility.
CAUTION
Do not attach a large key holder or
key case to either key. If it bangs
against your knees while you are
driving, it could turn the ignition
switch from the “ON ”position to the
“ Acc ”or “LOCK ”position, thereby
stopping the engine.
& Key number plate
The key number is stamped on the key
number plate attached to the key set.
Write down the key number and keep it in
another safe place, not in the vehicle. This
number is needed to make a replacement
key if you lose your key or lock it inside the
vehicle. Refer to “Key replacement ”F 2-3. Immobilizer
CAUTION
FCC WARNING
Changes or modifications not ex-
pressly approved by the party re-
sponsible for compliance could void
the user ’s authority to operate the
equipment.
The immobilizer system is designed to
prevent an unauthorized person from
starting the engine. Only keys registered
with your vehicle ’s immobilizer system can
be used to operate your vehicle. Even if
an unregistered key fits into the ignition
switch and can be turned to the “START ”
position, the engine will automatically stop
after several seconds.
Each immobilizer key contains a trans-
ponder in which the key ’s ID code is
stored. When a key is inserted into the
ignition switch and turned to the “ON ”
position, the transponder transmits thekey ’s ID code to the immobilizer system ’s
receiver. If the transmitted ID code
matches the ID code registered in the
immobilizer system, the system allows the
engine to be started. Since the ID code is
transmitted and acted upon almost in-

stantly, the immobilizer system does not
impede normal starting of the engine.
If the engine fails to start, pull out the key
once before trying again. Refer to“Ignition
switch ”F 3-3.
This device complies with Part 15 of
the FCC Rules and RSS-Gen of IC
Rules. Operation is subject to the
following two conditions: (1) this de-
vice may not cause harmful interfer-
ence, and (2) this device must accept
any interference received, including
interference that may cause undesiredoperation.
CAUTION
. Do not place the key under direct
sunlight or anywhere it may
become hot.
. Do not get the key wet. If the key
gets wet, wipe it dry with a cloth
immediately.
NOTE
To protect your vehicle from theft,
please pay close attention to the fol-
lowing security precautions: . Never leave your vehicle unattended
with its keys inside. . Before leaving your vehicle, close all windows and the moonroof, and lock
the doors and rear gate..
Do not leave spare keys or any
record of your key number in thevehicle. & Security ID plate
1) Key number plate
2) Security ID plate
The security ID is stamped on the security
ID plate attached to the key set. Write
down the security ID and keep it in
another safe place, not in the vehicle.
This number is needed to make a replace-
ment key if you lose your key or lock it
inside the vehicle.
This number is also needed for replace-
ment or repair of the engine control unit, integrated unit, and combination meter. &
Security indicator light
Refer to “Security indicator light ”F 3-25.
& Key replacement
Your key number plate and security ID
plate will be required if you ever need a
replacement key made. Any new key must
be registered for use with your vehicle ’s
immobilizer system before it can be used.
Up to four keys can be registered for use
with one vehicle.
For security, all the keys registered with
your vehicle ’s immobilizer system will
have their ID codes erased and re-
registered when a new key is made.
Therefore, all of your vehicle ’s keys must
be presented when a new key is regis-
tered. Any key that is not re-registered
when a new key is made cannot be used
after the other keys are re-registered. For
information on replacement keys and on
the registration of keys with your immo-
bilizer system, co ntact your SUBARU
dealer.
NOTE
A vehicle that is equipped with the
remote engine start system as a dealer
option can register up to three keys for Keys and doors

1) Negative ( ) side facing up
3. Replace with a new battery (type CR2025 or equivalent) making sure to
install the new battery with the negative( ) side facing up.
4. Refit the removed half of the transmit-
ter case.
After the battery is replaced, the trans-
mitter must be synchronized with the
remote keyless entry system ’s control
unit. Press either the “
”or “”button
six times to synchronize the unit. & Replacing lost transmitters
If you lose a transmitter or want to
purchase additional transmitters (up to
four can be programmed), you should re-
program all of your transmitters for secur- ity reasons. It is recommended that you
have your dealer program all of your
transmitters into your system. !
Programming the transmitters
The remote keyless entry system is
equipped with a special code learning
feature that allows you to program new
transmitter codes into the system or to
delete old ones. The system can learn up
to four unique transmitter codes. The four
transmitter codes may be the same or
different.
Programming transmitter codes into system:
Bag containing transmitter
Transmitter circuit board
To register a new transmitter with the
remote keyless entry system, it is neces-
sary to program the transmitter ’s code
(identification number) into the system. A
label showing the code is affixed to the
bag containing the transmitter, and an-
other is affixed to the circuit board inside
the transmitter. If there is no bag, open the
transmitter case and make a note of the
eight-digit number. Program the number
into the system in accordance with the
following procedure:
1. Firmly close the doors and the rear
gate, or trunk lid.
2. Open the driver ’s door, sit in the
driver ’s seat, and close the door.
3. Perform the following steps within 45 seconds.

NOTE
If you do not start entering the number
using the lock switch before the elec-
tronic tone stops sounding, an error
will occur. In this event, perform the
procedure again beginning with part 3.
9. When you have finished entering the
code a second time, an electronic tone will
sound for 1 second and automatic door
locking and unlocking operation will take
place once to indicate completion of
registration, provided the code entered
the second time is identical to that entered
the first time. NOTE
If the code entered the second time is
not identical to the code entered the
first time, an error will occur. In this
event, perform the procedure again
beginning with part 5. If an error occurs
five times, perform the procedure again
starting with part 3.
10. If you wish to program another trans-
mitter code into the system (up to four
transmitter codes can be programmed into
the system), perform the procedure begin-
ning with part 4. When you have finished
programming all of the necessary trans-
mitter codes into the system, remove the
key from the ignition switch.11. Test every registered transmitter to
confirm correct operation. !
Deleting old transmitter codes
The control unit of the remote keyless
entry system has four memory locations to
store transmitter codes, giving it the ability
to operate with up to four transmitters.
When you lose a transmitter, the losttransmitter ’s code remains in the memory.
For security reasons, lost transmitter
codes should be deleted from the mem-
ory.
To delete old transmitter codes, program
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.

ing that the system has been armed for surveillance.
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 remote
transmitter ’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
transmitter (i.e. the transmitter is lost,
broken or the transmitter battery is too
weak), you can disarm the system without
using the transmitter as follows. . Turn the ignition switch from the
“ LOCK ”to the “ON ”position with a
registered key. & Valet mode
When you choose the valet mode, the
alarm system does not operate. In valet
mode, the remote transmitter is used only for locking and unlocking the doors and
rear gate (5-door) and panic activation.
To enter the valet mode, change the
setting of your vehicle
’s alarm system for
deactivation mode. Refer to “Activating
and deactivating the alarm system ”F 2-
16. The security indicator light will con-
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 2-16.
& 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.

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
