!If the front passenger ’s frontal air-
bag ON indicator illuminates and the
OFF indicator turns off even when
an infant or a small child is in a child
restraint system (including boosterseat)
Turn the ignition switch to the “LOCK ”
position 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
system (including booster seat). Remove
the child restraint system from the seat. By
referring to the child restraint manufac-turer ’s recommendations as well as the
child restraint system installation proce-
dures in “Child restraint systems ”F 1-21,
correctly install the child restraint system.
Turn the ignition switch to the “ON ”
position and make sure that the frontpassenger ’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.
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
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 toSeat, seatbelt and SRS airbags

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 off, take the followingactions. . Turn the ignition switch to the “LOCK ”
position.. Ensure that there are no articles, books, shoes, or other objects 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. . 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 turn off for 2 seconds. Now, the ON
indicator should illuminate while the OFF

1-46Seat, seatbelt and SRS airbags
The SRS airbag can function only when
the ignition switch is in the “ON ”position.
The SUBARU advanced frontal airbag
system is designed to determine the
activation or deactivation condition of the
front passenger ’s SRS frontal airbag
depending on the total load on the frontpassenger ’s seat monitored by the front
passenger ’s occupant detection system
weight sensor. For this reason, only thedriver ’s SRS frontal airbag may deploy in
the event of a collision, but this does not
mean failure of the system.
If the front sub sensors and the impact
sensors in the airbag control module
detect a predetermined amount of force
during a frontal collision, the control
module sends signals to the airbag
module(s) (only driver ’s module or both
driver ’s and front passenger ’s modules)
instructing the module(s) to inflate the
SRS frontal airbag(s). The driver ’s and
front passenger ’s SRS frontal airbags use
dual stage inflators.
The two inflators of each airbag are
triggered either sequentially or simulta-
neously, depending on the severity of
impact, in the case of the driver ’s SRS
frontal airbag and depending on the
severity of impact and the total load on
the seat in the case of the front passen-ger ’s SRS frontal airbag. After deployment, the SRS airbag imme-
diately starts to deflate so that the driver
’s
vision is not obstructed. The time required
from detecting impact to the deflation of
the SRS airbag after deployment is short-
er than the blink of an eye.
Both when only the driver ’s SRS frontal
airbag deploys and the driver ’s and front
passenger ’s SRS frontal airbags deploy,
the driver ’s and front passenger ’s seatbelt
pretensioners operate at the same time.
Although it is highly unlikely that the SRS
airbag would activate in a non-accident
situation, should it occur, the SRS airbag
will deflate quickly, not obscuring vision
and will not interfere with the driver ’s
ability to maintain control of the vehicle.
When the SRS airbag deploys, a sudden,
fairly loud inflation noise will be heard and
some smoke will be released. These
occurrences are a normal result of the
deployment. This smoke does not indicate
a fire in the vehicle.
CAUTION
Do not touch the SRS airbag system
components around the steering
wheel and dashboard with bare
hands right after deployment. Doing
so can cause burns because the components can be very hot as a
result of deployment.
The driver ’s SRS frontal airbag and front
passenger ’s SRS frontal airbag are de-
signed to deploy in the event of an
accident involving a moderate to severe
frontal collision. It is basically not designed
to deploy in lesser frontal impacts be-
cause the necessary protection can be
achieved by the seatbelt alone. Also, they
are basically not designed to deploy in
side or rear impacts or in roll-over acci-
dents because deployment of only thedriver ’s SRS frontal airbag or both driver ’s
and front passenger ’s SRS frontal airbags
would not help the occupant in those
situations. The driver ’s and front passen-
ger ’s SRS frontal airbags are designed to
function on a one-time-only basis.
SRS airbag deployment depends on the
level of force experienced in the passen-
ger compartment during a collision. That
level differs from one type of collision to
another, and it may have no bearing on
the visible damage done to the vehicleitself.

1-52Seat, seatbelt and SRS airbags
A hands-free microphone or
other accessory in such a loca-
tion could be propelled through
the cabin with great force by the
curtain airbag, or it could prevent
correct deployment of the curtain
airbag. In either case, the result
could be serious injuries.
. Never hang or place coat hangers
or other hard or pointed objects
near the side windows. If such
items are present when the SRS
curtain airbags deploy, they
could be thrown through the
passenger compartment and
cause serious injuries. They
could also prevent proper opera-
tion of the SRS curtain airbags.WARNING
Do not put any kind of cover or
clothes or other objects over either
front seatback and do not attach
labels or stickers to the front seat
surface on or near the SRS side
airbag. They could prevent proper
deployment of the SRS side airbag,
reducing protection available to the
front seat ’s occupant.
! Operation
The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the “ON ”position.
The driver ’s and front passenger ’s SRS
side airbags and SRS curtain airbags deploy independently of each other since
each has its own impact sensor. There-
fore, they may not both deploy in the same
accident. Also, the SRS side airbag and
SRS curtain airbag deploys independently
of the driver
’s and front passenger ’s SRS
frontal airbags in the steering wheel and
instrument panel.
An impact sensor, which senses impact
force, is located in each of the left and
right center pillars and rear wheel houses.
Another impact sensor, which also senses
impact force, is located under the rear
center seat. If one of the center pillar
impact sensors and the impact sensor that
is located under the rear center seat
together sense an impact force above a
predetermined level in a side collision, the
control module causes both the SRS side
airbag and curtain airbag on the impacted
side to inflate regardless of whether the
rear wheel house impact sensor on the
same side senses an impact. If one of the
rear wheel house impact sensors and the
impact sensor that is located under the
rear center seat together sense an impact
force above a predetermined level, the
control module causes only the SRS
curtain airbag on the impacted side toinflate.
After the deployment, the SRS side airbag

“ 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
