2012 SUBARU IMPREZA WRX keyless

&Tire pressures
Check 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, referto “Tires and wheels ”F 11-23.
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 anaccident. &

&Replacing the battery
CAUTION
. Do not let dust, oil or water get on
or in the transmitter when repla-
cing the battery.
. Be careful not to damage the
printed circuit board in the trans-
mitter when replacing the battery.
. Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
. There is a danger of explosion if
an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
When the transmitter battery begins to get
weak, transmitter range will begin to
decrease. Replace the battery as soon
as possible. To replace the battery:
1. Open the transmitter case using a flat-
head screwdriver.
2. Remove the old battery from the
holder.
1) Negative (
) side facing up
3. Replace with a new battery (type CR2025 or equivalent) making sure to
install the new battery with the negative( ) side facing up.
4. Refit the removed half of the transmit-
ter case.
After the battery is replaced, the trans-
mitter must be synchronized with the
remote keyless entry system ’s control
unit. Press either the “
”or “”button
six times to synchronize the unit. & Replacing lost transmitters
If you lose a transmitter or want to
purchase additional transmitters (up to
four can be programmed), you should re-
program all of your transmitters for secur- Keys and doors

ity reasons. It is recommended that you
have your dealer program all of your
transmitters into your system. ! Programming the transmitters
The remote keyless entry system is
equipped with a special code learning
feature that allows you to program new
transmitter codes into the system or to
delete old ones. The system can learn up
to four unique transmitter codes. The four
transmitter codes may be the same ordifferent.
Programming transmitter codes into system:
Bag containing transmitter
Transmitter circuit board
To register a new transmitter with the
remote keyless entry system, it is neces-
sary to program the transmitter ’s code
(identification number) into the system. A
label showing the code is affixed to the
bag containing the transmitter, and an-
other is affixed to the circuit board inside
the transmitter. If there is no bag, open the
transmitter case and make a note of the
eight-digit number. Program the number
into the system in accordance with the
following procedure:
1. Firmly close the doors and the rear
gate, or trunk lid.
2. Open the driver ’s door, sit in the
driver ’s seat, and close the door.
3. Perform the following steps within 45 seconds.(1) Open and close the driver ’s door
once.
1) ON
2) LOCK
(2) Insert the key into the ignition
switch, then turn it from the “LOCK ”

2-14Keys and doors
7. Perform parts 5 and 6 of the procedure
for each of the remaining digits of the
transmitter code beginning with the sec-
ond digit (counting from the left) and
finishing with the eighth digit. NOTE . When you finish entering the eighth
digit, an electronic tone will sound for
30 seconds.. If the interval between one push of
the switch and the next exceeds 5
seconds, an error will occur. In this
event, perform the procedure again
beginning with part 4. If an error occurs
six times, perform the procedure again
starting with part 3.
8. Before the electronic tone stops
sounding, use the power door lock switch
to reenter the transmitter code beginning
with the leftmost digit. NOTE
If you do not start entering the number
using the lock switch before the elec-
tronic tone stops sounding, an error
will occur. In this event, perform the
procedure again beginning with part 3.
9. When you have finished entering the
code a second time, an electronic tone will
sound for 1 second and automatic door
locking and unlocking operation will take place once to indicate completion of
registration, provided the code entered
the second time is identical to that entered
the first time.
NOTE
If the code entered the second time is
not identical to the code entered the
first time, an error will occur. In this
event, perform the procedure again
beginning with part 5. If an error occurs
five times, perform the procedure again
starting with part 3.
10. If you wish to program another trans-
mitter code into the system (up to four
transmitter codes can be programmed into
the system), perform the procedure begin-
ning with part 4. When you have finished
programming all of the necessary trans-
mitter codes into the system, remove the
key from the ignition switch.
11. Test every registered transmitter to
confirm correct operation. ! Deleting old transmitter codes
The control unit of the remote keyless
entry system has four memory locations to
store transmitter codes, giving it the ability
to operate with up to four transmitters.
When you lose a transmitter, the losttransmitter ’s code remains in the memory.
For security reasons, lost transmitter codes should be deleted from the mem-
ory.
To delete old transmitter codes, program
four transmitter codes into the system. If
you have only one current transmitter,
program it four times. If you have two
current transmitters, program each one
twice. If you have three current transmit-
ters, program two of them once and the
third one twice. This process will leave
only current transmitter codes in thesystem
’s memory.
NOTE
Make sure no one else is operating
their keyless entry system within range
of your vehicle when programming
transmitters. If someone else were to
operate their remote transmitter while
you are programming your transmit-
ters, it is possible that their transmitter
code will be programmed into your
system, allowing them unauthorized
access to your vehicle.
