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.

Warning and Indicator Lights
138engine at the first safe opportunity and
contact your nearest SUBARU dealer
immediately.■ AT OIL TEMP Warning
Light (AT Models) If this light illuminates when the engine is
running, it may indicate that the transmis-
sion fluid temperature is too hot.
If the light illuminates while driving, imme-
diately stop the vehicle in a safe place and
let the engine idle until the warning light
turns off.■ Low Tire Pressure
Warning Light (If
Equipped)When the ignition switch is turned to the
“ON” position, the low tire pressure
warning light will illuminate for approxi-
mately 2 seconds to check that the tire
pressure monitoring system (TPMS) is
functioning properly. If there is no problem
and all tires are properly inflated, the light
will go out.
Each tire, including the spare (if provided),
should be checked monthly when cold
and inflated to the inflation pressure
recommended by the vehicle manufac-
turer on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the

proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that illumi-
nates a low tire pressure telltale when one
or more of your tires is significantly under-
inflated. Accordingly, when the low tire
pressure telltale illuminates, you should
stop and check your tires as soon as
possible, and inflate them to the proper
pressure. Driving on a significantly under-
inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TP MS is not a substi-
tute for proper tire maintenance, and it is
the driver’s responsibility to maintain
correct tire pressure, even if under-infla-
tion has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is no t operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure tell-
tale. When the system detects a malfunc-
tion, the telltale will flash for approximately one minute and then remain continuously

illuminated. This sequence will continue
upon subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after replacing
one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.
Should the warning light illuminate
steadily after blinking for approximately
one minute, have the system inspected by
your nearest SUBARU dealer as soon as
possible.
WARNING
If this light does not illuminate
briefly after the ig nition switch is
turned on or the light illuminates
steadily after blinking for approxi-
mately one minute, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
