& Safety precautions
WARNING
If you wear an implanted pacemaker
or an implanted defibrillator, stay at
least 8.7 in (22 cm) away from the
transmitting antennas installed on
the vehicle.
The radio waves from the transmit-
ting antennas on the vehicle could
adversely affect the operation of
implanted pacemakers and im-
planted defibrillators. If you wear electric medical equip-
ment other than an implanted pace-
maker or an implanted defibrillator,
before using the keyless access
with push-button start system, refer
to “ Radio waves used for the key-
less access with push-button start
system ” mentioned later, and con-
tact the electric medical equipment
manufacturer for more information.
The radio waves from the transmit-
ting antennas on the vehicle could
adversely affect the operation of the
electric medical equipment.
“ Radio waves used for the keyless
access with push-button start sys-
tem ”
. The keyless access with push-
button start system uses radio
waves of the following fre-
quency* in addition to the radio
waves used for the remote key-
less entry system. The radio
waves are periodically output
from the antennas installed on
the vehicle as shown in the
following illustrations.
* Radio frequency: 134 kHz2-10

NOTE . The operational/non-operational
setting for the keyless access function
can be changed. For the setting proce-
dure, refer to “ Disabling keyless ac-
cess function ” F 2-16. The setting can
also be changed by a SUBARU dealer.
For more details, contact a SUBARU
dealer.
. For detailed information about the
operation method for the push-button
ignition switch while the keyless ac-
cess function is switched to the non-
operational mode, refer to “ Access key
– if access key does not operate
properly ” F 9-16.
. The keyless access with push-but-
ton start system uses weak radio
waves. The status of the access key
and environmental conditions may in-
terfere with the communication be-
tween the access key and the vehicle
under the following conditions, and it
may not be possible to lock or unlock
the doors or start the engine.
– When operating near a facility
where strong radio waves are trans-
mitted, such as a broadcast station and power transmission lines
– When products that transmit
radio waves are used, such as an
access key or a remote transmitter
key of another vehicle
– When the access key is placed
near wireless communication
equipment such as a cell phone
– When the access key is placed
near a metallic object
– When metallic accessories are
attached to the access key
– When carrying the access key
with electronic appliances such as
a laptop computer
– When the battery of the access
key is discharged
. The access key is always commu-
nicating with the vehicle and is con-
tinuously using the battery. Although
the life of the battery varies depending
on the operating conditions, it is ap-
proximately 1 to 2 years. If the battery
becomes fully discharged, replace it
with a new one.
. If an access key is lost, it is
recommended that the remaining ac-
cess key be reregistered. For reregis-
tration of an access key, contact a
SUBARU dealer.
. For a spare access key, contact a
SUBARU dealer. . Up to 7 access keys can be regis-
tered for one vehicle.
. Carefully store the key number plate
supplied with the access key. It is
necessary for vehicle repair.
. Do not leave the access key in the
storage spaces inside the vehicle, such
as the door pocket, dashboard and the
rear shelf. Vibrations may damage the
key or turn on the switch, possibly
resulting in a lockout.
. After the vehicle battery is dis-
charged or replaced, initialization of
the steering lock system may be re-
quired 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

Ignition switch (models with-
out push-button start sys-
tem) 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 ignition
switch.
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.3-4
