Immobilizer
1082-2. ImmobilizerThe 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. If
engine start is attempted with an unregis-
tered access key fob or key, the engine
will not start. Even if the engine does start,
it will stop after a few seconds. This
system, however, is not a 100% anti-theft
guarantee.NOTE To protect your ve hicle from theft,
please pay close attention to the
following security precautions: - Never leave your vehicle unat-
tended with its keys inside. - Before leaving your vehicle,

close all windows and lock the
doors.
- Do not leave spare keys or any
record of your key number in the
vehicle.
 The vehicle has a maintenance-free
type immobilizer system.
■ Security Indicator LightRefer to "Security Indicator Light" P148.■ Key ReplacementYour key number 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. The maximum
number of keys that can be registered for
use with one vehicle is seven.
One key that has already been registered
is required in order to register a new key.NOTEIf you lose a key, the lost key’s ID code
still remains in the memory of the vehi-
cle’s immobilizer system. For security
reasons, the lost key’s ID code should
be erased from the memory. To erase
the lost key’s ID code, all keys that will
be used are required. For details about new key registration

and erasing the lost key’s ID code,
contact your SUBARU dealer.
■ Certification for Immobilizer
SystemRefer to "Certificati on for Keyless Access
with Push-Button Start System" P106.
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. Do not modify or remove the
system. If modified or removed,
the proper operation of the
system cannot be guaranteed.

 Turn the push-button ignition switch to
the “ACC” position.NOTEOnly registered keys will stop the
alarm. If the immobilizer transponder
is not registered, the alarm will not

2-6. WindowsNOTE In order to make opening and
closing the doors easier, completely
closed windows are linked to door
operations. Therefore, when a door is
opened, its window opens slightly. When a door is closed, its window

closes completely. However, if the
battery has discharged or is discon-
nected, this function will not operate.
 If the power window system detects
resistance, an impact or abnormality,
the window operation may be automat-
ically stopped to prevent further
jamming, entrapment or malfunction.
- The closing window slides down
slightly and stops.
- The opening window stops
sliding down.
 The power window system may
detect resistance, an impact or an
abnormality in the following cases. - A substantial sized object is
caught between the window and the
roof side (between the front pillar
and a point over the rear seat).
- A foreign object is caught
between the window and the roof
side (between the front pillar and a
point over the rear seat).
- The vehicle drives over a deep
pothole.
 The window cannot be closed for a
few seconds after th e window is auto-
matically stopped by the system.

To avoid serious personal injury
caused by entrapment, always con-
form to the follo wing instructions
without exception. When operating the power
