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)

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 3-23.
& 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

Ignition switch
WARNING
. Never turn the ignition switch to
“ LOCK ”while the vehicle is
being driven or towed because
that will lock the steering wheel,
preventing steering control. And
when the engine is turned off, it
takes a much greater effort than
usual to steer.
. Before leaving the vehicle, al-
ways remove the key from the
ignition switch for safety and
never allow an unattended child
to remain in the vehicle. Failure
to follow this procedure could
result in injury to a child or
others. Children could operate
the power windows, the moon-
roof or other controls or even
make the vehicle move.
CAUTION
Do not attach a large key holder or
key case to either key. If it banged
against your knees or hands while
you are driving, it could turn the
ignition switch from the “ON ”posi- tion to the
“Acc ”or “LOCK ”posi-
tion, thereby stopping the engine.
Also, if the key is attached to a
keyholder or to a large bunch of
other keys, centrifugal force may act
on it as the vehicle moves, resulting
in unwanted turning of the ignitionswitch.
The ignition switch has four positions:
LOCK, Acc, ON and START. NOTE . Keep the ignition switch in the
“ LOCK ”position when the engine is
not running. . Using electrical accessories for a
long time with the ignition switch in the“ ON ”or “Acc ”position can cause the battery to go dead..
If the ignition switch will not move
from the “LOCK ”position to the “Acc ”
position, turn the steering wheel
slightly to the left and right as you turn
the ignition switch. & LOCK
The key can only be inserted or removed
in this position. The ignition switch will lock
the steering wheel when you remove the
key.
If turning the key is difficult, turn the
steering wheel slightly to the right and left
as you turn the key.
The key can be turned from “Acc ”to
“ LOCK ”only when the key is pushed in
