2009 SUBARU LEGACY ECU

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 passenger ’s occupant detection sys-
tem weight sensor 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“ Manual seat ”in the front seats section in
Chapter 1 in this Owner ’s Manual. (Mod-
els equipped with manual seats only)

. 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. (Models
equipped with manual seats only)
If the ON indicator still illuminates while
the OFF indicator extinguishes after taking
relevant correctiv e actions described
above, relocate the child restraint system
to the rear seat and immediately contact
your SUBARU dealer for an inspection.
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 illuminates while the OFF
indicator extinguishes), take the follow-
ing 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 illuminates while
the OFF indicator extinguishes despite the fact that the actions noted above
have been taken, seat the child/small
adult in the rear seat and immediately
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 is met regarding the front passen-ger ’s seat.
. When the seat is occupied by an adult.
. When a heavy article is placed on the
seat.
When the front passenger ’s seat is occu-
pied by an adult, observe the following
precautions. Failure to do so may lessen
the load on the front passenger ’s seat,
deactivating the front passenger ’s SRS
frontal airbag despite the fact that the seat
is occupied by an adult. .
Do not allow the rear seat occupant to
lift the front passenger ’s seat cushion
using his/her feet. . Do not place any article under the front
passenger ’s seat, or squeeze any article
from behind and under the seat. This may
lift the seat cushion. . Do not squeeze any article between
the front passenger ’s seat and side trim/
pillar, door or center console box. This
may lift the seat cushion. ! If the passenger ’s frontal airbag OFF
indicator illuminates and the ON
indicator extinguishes even when
the front passenger ’s seat is occu-
pied by an adult
This can be caused by the adult incor-
rectly sitting in the front passenger ’s seat.
Turn the ignition switch to the “LOCK ”
position. Ask the front passenger to set
the seatback to the upright position, sit up
straight in the center of the seat cushion,
correctly fasten the seatbelt, position his/
her legs out forward, and adjust the seat to
the rearmost position. Turn the ignition
switch to the “ON ”position. If the OFF
indicator remains illuminated while the ON
indicator remains extinguished, take the
following actions. . Turn the ignition switch to the “LOCK ”
position.

.Ensure that there is no article, book,
shoe, or other object trapped under the
seat, at the rear of the seat, or on the side
of the seat. . 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. (Models
equipped with manual seats only) . Next, turn the ignition switch to the
“ ON ”position and wait 6 seconds to allow
the system to complete self-checking.
Following the system check, both indica-
tors extinguish for 2 seconds. Now, the
ON indicator should illuminate while the
OFF indicator remains extinguished.
If the OFF indicator still illuminates while
the ON indicator remains extinguished,
ask the occupant to move to the rear seat
and immediately contact your SUBARU
dealer for an inspection. ! Effect vehicle modifications made

& Key number
1) Key number plate
2) Security ID 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 thevehicle.
For information on making replacement
keys for vehicles with the immobilizer
system, refer to the
“Immobilizer ”section
in this chapter.

Immobilizer
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 does not start, pull out the
key once before trying again. Refer to the“ Ignition switch ”section in chapter 3.
This device complies with Part 15 of
the FCC Rules and with RSS-210 of
Industry Canada. Operation is subject
to the following two conditions: (1) This device may not cause harmful inter-
ference, and (2) this device must
accept any interference received, in-
cluding interference that may cause

& Security indicator light
Vehicle with SI-DRIVE
Vehicle without SI-DRIVE
The security indicator light deters potential
thieves by indicating that the vehicle is equipped with an immobilizer system. It
begins flashing approximately 60 seconds
after the ignition switch is turned from the“
ON ”position to the “Acc ”or “LOCK ”
position or immediately after the key is
pulled out.
If the security indicator light does not flash,
the immobilizer system may be faulty. If
this occurs, contact your SUBARU dealer
as soon as possible.
In case an unauthorized key is used (e.g.
an imitation key), the security indicator
light illuminates.
NOTE
Even if the security indicator light
flashes irregularly or its fuse blows
(the light does not flash if its fuse is
blown), the immobilizer system will
function normally. & 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, contact your SUBARU
dealer.
NOTE
A vehicle that is equipped with the
remote engine start system as the
dealer option can register up to three
keys for use with one vehicle.

&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 ordifferent. Programming transmitter codes intosystem:
Key unit tag
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
tag showing the code is affixed to the key
unit, and another is affixed to the circuit
board inside the transmitter. If there is no
tag, 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 (Station wagon) or trunk lid (Sedan).
2. Open the driver ’sdoor,sitonthe
driver ’s seat, and close the door.
3. Perform the following steps within 45 seconds.(1) Open and close the driver ’s door
once. Keys and doors
