Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
CAUTION
When the front passenger’s seat is
occupied by an infant in an appro-
priate child restraint system, ob-
serve the following precautions.
Failure to do so may increase the
load on the front passenger ’s seat,
activating the front passenger ’s
SRS frontal airbag even though that
seat is occupied by an infant.
. Do not place any article on the
seat other than the infant in the
child restraint system.
. Do not place more than one
infant in the child restraint sys-
tem.
. Do not install any accessory
such as a table or TV onto the
seatback.
. Do not store a heavy load in the
seatback pocket.
. Do not allow the rear seat occu-
pant to place his/her hands or
legs on the front passenger ’s
seatback, or allow him/her to pull
the seatback. !
If the front passenger ’s frontal
airbag ON indicator illuminates
and the OFF indicator turns off
even when an infant or a small
child is in a child restraint sys-
tem (including booster seat)
1. Turn the ignition switch to the “LOCK” /
“OFF ”position.
2. Remove the child restraint system
from the seat.
3. By referring to the child restraint
manufacturer ’s recommendations as well
as the child restraint system installation
procedures in “Child restraint systems ”
F 1-27, correctly install the child restraint
system.
4. Turn the ignition switch to the “ON”
position and make sure that the front
passenger ’s frontal airbag ON indicator
turns off and the OFF indicator illuminates.
If still 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 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. (Models
equipped with manual seats only)
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 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. Children should always wear a
seatbelt when sitting in the seat irre-
spective of whether the airbag is
deactivated or activated. If the front
passenger ’s SRS frontal airbag is acti-
vated (the ON indicator remains illumi-
nated 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-
1-54

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 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.
CAUTION
When the front passenger ’s seat is
occupied 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. This may
result in personal injury.
. Do not allow the rear seat occu-
pant 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 be-
tween the front passenger ’s seat
and side trim/pillar, door or cen-
ter console box. This may lift the
seat cushion.
! If the passenger ’s frontal airbag
OFF indicator illuminates and
the ON indicator turns off even
when the front passenger ’s seat
is occupied by an adult
This can be caused by the adult incor-
rectly sitting in the front passenger ’s seat.
1. Turn the ignition switch to the “LOCK”/
“OFF ”position.
2. 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.
3. Turn the ignition switch to the
“ON”
position.
If the OFF indicator remains illuminated
while the ON indicator remains off, take
the following actions.
1. Turn the ignition switch to the “LOCK”/
“OFF ”position.
2. 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.
3. Ensure that the backward-forward
position 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)
4. Turn the ignition switch to the “ON”
position and wait 6 seconds to allow the
system to complete self-checking. Follow-
ing the system check, both indicators turn
off for 2 seconds. Now, the ON indicator
should illuminate while the OFF indicator
remains off.
If the OFF indicator still remains illumi-
nated while the ON indicator remains off,
ask the occupant to move to the rear seat
and immediately contact your SUBARU
dealer for an inspection.

Keys and doors/Immobilizer
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. This
system, however, is not a 100% anti-theft
guaranty.
For models with “keyless access with
push-button start system ”:
If you press the push-button ignition
switch when carrying an unregistered
access key, the switch will not turn to the
“ON ”position and the engine will not start.
If the engine does not start, perform the
procedure described in “Starting engine”
F 9-19.
For models without “keyless access
with push-button start system ”:
Even if an unregistered key fits into the
ignition switch and can be turned to the
“START ”position, the engine will auto-
matically stop after several seconds.
If the engine does not start, pull out the
key once before trying again. Refer to
“ Ignition switch (models without push-
button start system) ”F 3-4.
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.
. Do not modify or remove the
system. If modified or removed,
the proper operation of the sys-
tem cannot be guaranteed.
NOTE
. To protect your vehicle from theft,
please pay close attention to the fol-
lowing security precautions:
–Never leave your vehicle unat-
tended with its keys inside.
– Before leaving your vehicle,
close all windows and the moon-
roof, and lock the doors (all models)
and rear gate (Outback).
– Do not leave spare keys or any
record of your key number in the
vehicle.
. The vehicle has a maintenance-free
type immobilizer system.

Refer to “Security indicator light ”F 3-30.
& Key replacement
Your key number 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. The maximum
number of keys that can be registered
for use with one vehicle is as follows.
. Four (models without “keyless access
with push-button start system ”)

is required in order to register a new key.
If you lose a key, the lost key ’s ID code still
remains in the memory of the vehicle’ s
immobilizer system. For security reasons,
the lost key ’s ID code should be erased
from the memory. To erase the lost key ’s
ID code, all keys that will be used are
required.
For details about new key registration and
