& Tire pressuresCheck and, if necessary, adjust the
pressure of each tire (including the spare)
at least once a month and before any long
journey.
Check the tire pressure when the tires are
cold. Use a pressure gauge to adjust the
tire pressures to the values shown on the
tire placard. For detailed information, refer
to“Tires and wheels” F11-23.
WARNING
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to deform severely and to
rapidly become hot. A sharp in-
crease in temperature could cause
tread separation, and destruction of
the tires. The resulting loss of
vehicle control could lead to an
accident.

General information&Noise from under the vehicle
NOTEYou may hear a noise from under the
vehicle approximately 5 hours after the

Seat, seatbelt and SRS airbags
Seat heater (if equipped)The seat heater is equipped in the front
seats.
The seat heater operates when the igni-
tion switch is either in the “Acc”or “ON ”
position.
CAUTION
. There is a possibility that people
with delicate skin may suffer
slight burns even at low tempera-
tures if they use the seat heater
for a long period of time. When
using the heater, always be sure
to warn the persons concerned.
. Do not put anything on the seat
which insulates against heat,
such as a blanket, cushion, or
similar items. This may cause the
seat heater to overheat.NOTEUse of the seat heater for a long period
of time while the engine is not running
can cause battery discharge.
& Type A seat heater1) HI–Rapid heating
2) LO–Normal heating
3) OFF –Off
A) Left-hand side
B) Right-hand side
To turn on the seat heater, push the “LO”
or “HI ”position on the switch, as desired,
depending on the temperature.
Selecting the “HI”position will cause the
seat to heat up quicker.
To turn off the seat heater, lightly press the
opposite side of the current position.
The indicator located on the switch illumi-
nates when the seat heater is in operation.
When the vehicle ’s interior is warmed
enough or before you leave the vehicle,
be sure to turn the switch off.& Type B seat heaterEach seat heater has four levels of
adjustment. To use the heater in the
right-hand seat, turn the “R”adjustment
dial forward until the “

Keys and doors
Keys1) Master key (Black)
2) Submaster key (Black)
3) Valet key (Gray)
4) Key number plate
5) Security ID plateThree 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)
. Glove box
The valet key fits only the ignition switch and driver
’s door lock. You can keep the
trunk and 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 “LOCK ”position, thereby
stopping the engine.& Key number plateThe 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 the
key ’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-

Black plate (91,1)
北米Model "A1130BE-A" EDITED: 2011/ 6/ 7
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 undesired
operation.
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.NOTETo 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 the
vehicle.
& Security ID plate1) Key number plate
2) Security ID plateThe 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 replacementYour 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.NOTEA vehicle that is equipped with the
remote engine start system as a dealer
option can register up to three keys for
