Keys
1) Master key (black)
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
. Glove box
The valet key fits only the ignition switch
and driver ’s door lock. You can keep the 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 OFF position, thereby stop-
ping 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 thevehicle.
For information on making replacement
keys for vehicles with the immobilizer
system, refer to “Security ID plate ”F 2-3. Immobilizer
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.

Security indicator light
The security indicator light deters potential
thieves by indicating that the vehicle is
equipped with an immobilizer system. It
begins flashing in the following ways. .Once approximately every 3 sec-
onds:
–Approximately 60 seconds after the
ignition switch is turned from the “ON ”
position to the “Acc ”or “LOCK ”posi-
tion – Immediately after the ignition key is
pulled out
. Twice approximately every 2 sec-
onds:

for surveillance (Refer to “Arming the
system ”F 2-15.)
. Other flashing patterns:
The alarm system may have been trig-
gered by unauthorized intrusion or any
impact to the vehicle body. Refer to“ Tripped sensor identification ”F 2-18.
If the security indicator light does not flash,
the immobilizer system may be faulty. If
this occurs, contact your SUBARU dealer
as soon as possible.
In case an unauthorized key is used (e.g.
an imitation key), the security indicator
light illuminates.
NOTE
Even if the security indicator light
flashes irregularly or its fuse blows
(the light does not flash if its fuse is
blown), the immobilizer system will
function normally. & 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, contact 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
use with one vehicle. Door locks &

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 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

11. Test every registered transmitter to
confirm correct operation. !Deleting old transmitter codes
The control unit of the 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 lost transmit-ter ’s code remains in the memory. For
security reasons, lost transmitter codes
should be deleted from the memory.
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.
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 for 30
seconds.. The turn signal lights will flash for 30
