B) Security ID plate
The security ID is stamped on the metal plate attached
to the key set. Write down the security ID and keep it
in another safe place, not in the vehicle. This number

„Security indicator light
The security indicator light deters potential thieves by
indicating that the vehicle is equipped with an immobi-
lizer system. It begins flashing (approximately once
every three seconds) about 60 seconds after the igni-
tion switch is turned from the “ON” position to the
“ACC” or “LOCK” position or immediately after the key
is pulled out.
If the security indicator light does not flash, the immo-
bilizer system may be faulty. If this occurs, we recom-
mend that you contact your SUBARU dealer as soon
as possible.
In case an unauthorized key is used (e.g. an imitation
key), the security indicator light comes on.
NOTE
Even if the security indicator light flashes irregu-
larly or its fuse blows (the light does not flash if its
fuse is blown), the immobilizer system will func-
tion normally. „ Key replacement
Your key number and security ID will be required if you
ever need a replacement key made. Any new key
must be registered for use with your vehicle’s immobi-
lizer 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 registered. Any key that is not re-registered
when a new key is made cannot be used after the oth-
er keys are re-registered. For information on replace-
ment keys and on the registration of keys with your im-
mobilizer system, we recommend that you contact
your SUBARU dealer.

Remote keyless entry system
Two transmitters are provided for your vehicle.
The remote keyless entry system has the following
functions. yLocking and unlocking the doors (and rear gate on
the Wagon) without a key y Sounding a panic alarm
y Arming and disarming the security system (if your
vehicle is equipped with an optional security system).
See the next section “Security system (if equipped)”
for detailed information.
This device complies with Part 15 of the FCC
Rules and with RSS-210 of Industry Canada. Oper-
ation is subject to the following two conditions: (1)
This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved
by the party responsible for compliance could
void the user’s authority to operate the equipment.
The operable distance of the keyless entry system is
approximately 30 feet (10 meters). However, this dis-
tance will vary depending on environmental condi- tions. The system’s operable distance will be shorter
in areas near a facility or electronic equipment emitting
strong radio waves such as a power plant, broadcast
station, TV tower, or remote controller of home elec-
tronic appliances.
The remote keyless entry system does not operate
when the key is inserted in the ignition switch to pre-
vent accidental lockout.
y
Do not expose the transmitter to severe
shocks, such as those experienced as a result
of dropping or throwing. y Do not take the transmitter apart except when
replacing the battery. y Do not get the transmitter wet. If it gets wet,
wipe it dry with a cloth immediately.

A) 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. Reinstall the back half of the transmitter case by
snapping it back on.
After the battery is replaced, the transmitter must
be synchronized with the keyless entry system’s
control unit. Press either the “ ” or “ ” but- ton six times to synchronize the unit.
yDo not let dust, oil or water get on or in the
transmitter when replacing the battery. y Be careful not to damage the printed circuit
board in the transmitter when replacing the bat-
tery.
„ 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 security
reasons. It is recommended that you have your dealer
program all of your transmitters into your system. T 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 system can learn up to four unique transmit-
ter codes. The four transmitter codes may be the
same or different.

3. Press and release any button on the transmitter
that you wish to program into the system. The horn will
sound twice to indicate that the transmitter has been
programmed.
Any additional transmitters can also be programmed
at this time. Repeat steps 1 through 3 for an additional
transmitter.
To exit the programming mode:
1. After all of your transmitters are programmed, re-
move the key from the ignition switch.
The horn will sound three times to indicate that the
system has exited the programming mode.
2. Make sure that the keyless entry system properly
operates by operating each transmitter. T
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 transmitter’s code re-
mains in the memory. For security reasons, lost trans-
mitter codes should be deleted from the memory.
To delete old transmitter codes, program four trans-mitter codes into the system. If you have only one cur-
rent transmitter, program it four times. If you have two
current transmitters, program each one twice. If you
have three current transmitters, program two of them
once and the third one twice. This process will leave
only current transmitter codes in the system’s memo-ry.
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 transmitters, it is possible that
their transmitter code will be programmed into
your system, allowing them unauthorized access
to your vehicle.

Security system (if equipped)
The security 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 interrupted to
prevent starting the vehicle without a key.
The system can be armed and disarmed with the re-
mote transmitter.
The system does not operate when the key is inserted
into the ignition switch. „System operation
The security system will give the following alarm indi-
cations when triggered: y The turn signal lights will flash and the horn will
sound intermittently. In addition, the starter motor will
not operate. y The alarm automatically resets after 30 seconds;
however, the alarm will reactivate if the vehicle is tam-
pered with again. The alarm will continue for six times
if any sensor continues to be activated.
The alarm is triggered by: y Opening a door, the rear gate or trunk lid.
y Application of physical shock to the vehicle (e.g. forced entry). Note that there are two alarm levels for
shock: warning and alarm. In warning mode, the alarm
detects lower level vibrations and triggers 2 warning
chirps on the horn and two flashes on the lights as a
deterrent to would be vandals. In alarm mode, higher
levels of shock are detected and the system will go into full alarm. y
