ECU SUBARU IMPREZA 2011 4.G Owner's Manual

WARNING
Do not attach accessories to the
windshield, or fit an extra-wide mir-
ror over the rear view mirror. If the
SRS airbag deploys, those objects
could become projectiles that could
seriously injure vehicle occupants.
! Driver ’s SRS frontal airbag
The driver ’s SRS frontal airbag uses a
dual stage inflator. The inflator operates in
different ways depending on the severity
of impact.
Have the system inspected by your
SUBARU dealer immediately if the SRS
airbag system warning light illuminates. NOTE
The driver
’s SRS side airbag, SRS
curtain airbag and seatbelt preten-
sioner are not controlled by the
SUBARU advanced frontal airbag sys-tem. ! Front passenger ’s SRS frontal air-
bag
The front passenger ’s SRS frontal airbag
uses a dual stage inflator. The inflator
operates in different ways depending on
the severity of impact.
The total load on the seat is monitored by
the occupant detection system ’s weight
sensor located under the seat.
The system has another sensor that
monitors the tension of the front passen-
ger seatbelt. Using the total seat load and
seatbelt tension data from the sensors,
the occupant detection system determines
whether the front passenger ’s SRS frontal
airbag should or should not be inflated.
The occupant detection system may not
inflate the front passenger ’s SRS frontal
airbag even when the driver ’s SRS frontal
airbag deploys. This is normal.
Observe the following precautions. Failure
to do so may prevent the SUBARU
advanced frontal airbag system from
functioning correctly or cause the system
to fail. .
Do not apply any strong impact to the
front passenger ’s seat such as by kicking.
. Do not spill liquid on the front passen-
ger ’s seat. If liquid is spilled, wipe it off
immediately. . Do not remove or disassemble the front
passenger ’s seat.
. Do not install any accessory (such as
an audio amplifier) other than a genuine
SUBARU accessory under the front pas-senger ’s seat.
. Do not place anything (shoes, umbrel-
la, etc.) under the front passenger ’s seat.
. The front passenger ’s seat must not be
used with the head restraint removed. . Do not leave any article including a
child restraint system on the front passen- ger ’s seat or the seatbelt tongue and
buckle engaged when you leave yourvehicle. . Do not place a magnet near the
seatbelt buckle and the seatbelt retractor.. Do not use front seats with their back-
ward-forward position and seatback not
being locked into place securely. If any of
them are not locked securely, adjust them
again. For adjusting procedure, refer to“ Front seats ”F 1-2.

seat other than the child restraint system
and the child occupant. . Ensure that there is no article left in the
seatback pocket.. Ensure that the backward-forward po- sition and seatback of front passenger
’s
seat are locked into place securely by
moving the seat back and forth.
If the ON indicator still remains illuminated
while the OFF indicator turns off after
taking relevant corrective actions de-
scribed above, relocate the child restraint
system to the rear seat and immediately
contact your SUBARU dealer for aninspection. NOTE
When a child who has outgrown a child
restraint system or a small adult is
seated in the front passenger ’s seat,
the SUBARU advanced frontal airbag
system may or may not activate the
front passenger ’s SRS frontal airbag
depending on the occupant ’s seating
posture. If the front passenger ’s SRS
frontal airbag is activated (the ON
indicator remains illuminated while
the OFF indicator turns off), take the
following actions. . Ensure that no article is placed on
the seat other than the occupant. . Ensure that there is no article left in
the seatback pocket.
If the ON indicator still remains illumi-
nated while the OFF indicator turns off
despite the fact that the actions noted above have been taken, seat the child/
small adult in the rear seat and im-
mediately contact your SUBARU dealer
for an inspection. Even if the system
has passed the dealer inspection, it is
recommended that on subsequent trips
the child/small adult always take the
rear seat.
Children who have outgrown a child
restraint system should always wear the
seatbelt irrespective of whether the airbag
is deactivated or activated. !
Conditions in which front passen- ger’s SRS frontal airbag is activated
The front passenger ’s SRS frontal airbag
will be activated for deployment upon
impact when any of the following condi-
tions are met regarding the front passen- ger ’s seat.
. When the seat is occupied by an adult.
. When a heavy article is placed on the

Three 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

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 plate
The 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 thekey ’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-

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 undesiredoperation.
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.
NOTE
To 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 thevehicle. & Security ID plate
1) Key number plate
2) Security ID plate
The 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 3-25.
& Key replacement
Your 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.
NOTE
A vehicle that is equipped with the
remote engine start system as a dealer
option can register up to three keys for Keys and doors

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- 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 or
different.
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.

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.
