implanted pacemakers and
implanted defibrillators.If you wear electronic medical
equipment other than an implanted
pacemaker or an implanted
defibrillator, before using the key-
less access with push-button start
system, refer to “Radio waves used
for the keyless access with push-
button start system” mentioned
later, and contact the electronic
medical equipment manufacturer
for more information. The radio
waves from the tr ansmitting anten-
nas on the vehicle could adversely
affect the operation of the elec-
tronic medical equipment.“Radio waves used for the keyless

NOTEThe operational/non-operational
setting for the keyless access function
can be changed. For the setting proce-
dure, refer to "Disabling Keyless
Access Function" P103.
 For detailed info rmation about the
operation method fo r the push-button
ignition switch while the keyless
access function is switched to the non-
operational mode, refer to "Access Key
Fob – If Access Key Fob Does Not
Operate Properly" P325.
 The keyless access with push-
button start system uses weak radio
waves. The status of the access key
fob and environmental conditions may
interfere with the communication
between the access key fob and the
vehicle under the following conditions,
and it may not be possible to lock or
unlock the doors or start the engine.
CAUTION
 Never leave or store the access
key fob inside the vehicle or
within 6.6 ft (2 m) around the
vehicle (e.g., in the garage). The
access key fob may be locked
inside the vehicle, or the battery
may discharge rapidly. Note that
the push-button ignition switch
may not turn on in some cases
depending on the location of the
access key fob. The access key fob contains elec-
tronic components. Observe the
following precautions to prevent
malfunctions.
- It is recommended to have the
access key fob battery
replaced at an authorized
SUBARU dealer to avoid the
risk of damage.- Do not get the access key fob
wet. If the access key fob gets
wet, wipe it off immediately
and let it dry completely.- Do not apply strong impacts
to the access key fob.
- Never leave the access key
fob in direct sunlight or
anywhere that may become
hot, such as on the dash-
board. It may damage the
battery or cause circuit
malfunctions.- Do not wash the access key
fob in an ultrasonic washer.- Do not leave the access key
fob in humid or dusty loca-
tions. Doing so may cause
malfunctions.- Keep the access key fob away
from magnetic sources.- Do not leave the access key
fob near a personal computer
or home electrical appliance.- Do not leave the access key
fob near a battery charger or
any electrical accessories.- Do not apply metallic window
tint or attach metallic objects
to the windows.- Do not fit non genuine acces- sories or parts.
If the access key fob is dropped,
the integrated emergency key
inside may become loose. Be
careful not to lose the emergency
key.
 When traveling in an airplane, do
not press the button of the access
key fob. If any button of the
access key fob is pressed, radio
waves are emitted and may affect
the operation of the airplane. In a
bag, take measures to prevent the
buttons from being pressed acci-
dentally.

If an access key fob is lost, it is
recommended that all of the remaining
access key fobs be reregistered. For
reregistration of an access key fob,
contact a SUBARU dealer.
 For a spare access key fob, contact
a SUBARU dealer.
 Up to 7 access key fobs can be
registered for one vehicle.
 Do not leave the access key fob in
the storage spaces inside the vehicle,
such as the door pocket, dashboard or
inside the corner of the trunk. Vibra-
tions may damage the access key fob
or turn on the switch, possibly
resulting in a lockout.
 After the vehicle battery is
discharged or replaced, initialization of
the steering lock system may be
required to start the engine. In this
case, perform the following procedure
to initialize the steering lock. (1) Turn the push -button ignition
switch to the “OFF” position. For
