Before driving
BRZ_U (A4450BE-A)
Using the mechanical key (vehicles with a keyless access with
push button start system)
To take out the mechanical key,
push the release knob and take
the key out.
After using the mechanical key,
store it in the access key. Carry
the mechanical key together with
the access key. If the access key
battery is depleted or the “keyless
access” entry function does not
operate properly, you will need
the mechanical key.
(→ P. 476)
■When required to leave the vehicle’s key with a parking attendant
Turn the trunk lid opener main switch off as circumstances demand.
(→ P. 47)
On vehicles without a keyless access with push button start system, provide
the attendant with the valet key.
On vehicles with a keyless access with push button start system, remove the
mechanical key for your own use and provide the attendant with the access
key only.
■ Key number plate
Keep the plate in a safe place, not in the vehicle. In the event that a key
(without a keyless access with push button start system) or mechanical key
(with a keyless access with push button start system) is lost, a new key can
be made at your SUBARU dealer using the key number plate. ( →P. 475)
■ When riding in an aircraft
When bringing a key with remote keyless entry system onto an aircraft,
make sure you do not press any buttons on the key while inside the aircraft
cabin. If you are carrying the key in your bag etc., ensure that the buttons
are not likely to be pressed accidentally. Pressing a button may cause the
key to emit radio waves that could interfere with the operation of the aircraft.

BRZ_U (A4450BE-A)
■Security feature
If a door is not opened within approximately 60 seconds after the vehicle is
unlocked, the security feature automatically locks the vehicle again. (How-
ever, depending on the location of the access key, the key may be detected
as being in the vehicle. In this case, the vehicle may be unlocked.)
■ Battery-saving function
The battery-saving function will be activated in order to prevent the access
key battery and the vehicle battery from being discharged while the vehicle
is not in operation for a long time.
●In the following situations, the keyless access with push button start sys-
tem may take some time to unlock the doors.
• The access key has been left in an area of approximately 6 ft. (2 m) of
the outside of the vehicle for 10 minutes or longer.
• The keyless access with push button start system has not been used for 5 days or longer.
● If the keyless access with push button start system has not been used for
14 days or longer, the doors cannot be unlocked at any door except the
driver’s door.
In this case, take hold of the driver’s door handle, or use the remote key-
less entry system or the mechanical key, to unlock the doors.

Conditions affecting operation
The keyless access with push button start system uses weak radio waves. In
the following situations, the communication between the access key and the
vehicle may be affected, preventing the keyless access with push button
start system, remote keyless entry system and engine immobilizer system
from operating properly. (Way of coping →P. 476)
● When the access key battery is depleted
● Near a TV tower, electric power plant, gas station, radio station, large dis-
play, airport or other facility that generates strong radio waves or electri-
cal noise
● When the access key is in contact with, or is covered by the following
metallic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
• Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
● When another transmitters (that emit radio waves) are being used nearby
● When carrying the access key together with the following devices that
emit radio waves
• A portable radio, cellular phone, cordless phone or other wireless com-
munication device
• Another vehicle's access key or a transmitter that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
● If window tint with a metallic content or metallic objects are attached to
the rear window
● When the access key is placed near a battery charger or electronic
devices

Access key battery depletion
● The standard battery life is 1 to 2 years.
● If the battery charge becomes low, a buzzer will sound in the cabin and a
message will be displayed on the multi-information display when the
engine is stopped. ( →P. 446)
● As the access key always receives radio waves, the battery will become
depleted even if the access key is not used. The following symptoms
indicate that the access key battery may be depleted. Replace the bat-
tery when necessary. ( →P. 392)
• The keyless access with push button start system or the remote key- less entry system does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the access key close to any
of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges
• Table lamps
■ When the access key battery is fully depleted
→ P. 392
■ If the keyless access with push button start system has been deacti-
vated in a customized setting
● Locking and unlocking the doors, unlocking the trunk lid: Use the remote
keyless entry system or mechanical key. ( →P. 38, 476)
● Starting the engine and changing push-button ignition switch modes:
→ P. 477
● Stopping the engine: →P. 4 7 9

cal noise
● When carrying a portable radio, cellular phone or other wireless commu-
nication devices
● When the transmitter is in contact with, or is covered by a metallic object

Window open/close function linked to door operation
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 disconnected, this function will
not operate. ( →P. 484)
■ If the keyless access with push button start system has been deacti-
vated in a customized setting (vehicles with a keyless access with
push button start system)
Use the remote keyless entry system or mechanical key. ( →P. 38, 476)
