!Conditions in which front passen- ger’s SRS frontal airbag is not
activated
The front passenger ’s SRS frontal airbag
will not be activated when any of the 
following conditions are met regarding the 
front passenger ’s seat:
. The seat is empty.
. The seat is equipped with a rearward
facing child restraint system and an infant
is restrained with it. (See WARNING thatfollows.) . The seat is equipped with a forward
facing child restraint system and a small 
child is restrained with it. (See WARNING
that follows.) . The seat is equipped with a booster
seat and a small child is in the booster 
seat. (See WARNING that follows.) . The seat is relieved of the occupant
load for a time exceeding the predeter- 
mined monitoring time period. . The seat is occupied by a child who
has outgrown a child restraint system 
(See WARNING that follows.) or by a
small adult. . The front passenger ’s occupant detec-
tion system is malfunctioning.WARNING
NEVER INSTALL A REARWARD FA- 
CING CHILD SEAT IN THE FRONT
PASSENGER ’S SEAT EVEN IF THE
FRONT PASSENGER ’S SRS FRON-
TAL AIRBAG IS DEACTIVATED. Be
sure to install it in the REAR seat in
a correct manner. Also, it is strongly
recommended that any forward fa-
cing child seat or booster seat be
installed in the REAR seat, and that
even children who have outgrown a
child restraint system be also
seated in the REAR seat. This is
because children sitting in the frontpassenger ’s seat may be killed or
severely injured should the frontpassenger ’s SRS frontal airbag de-
ploy. REAR seats are the safest
place for children.
CAUTION
When the front passenger ’s seat is
occupied by a child, observe 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 a child. .
Do not place any article on the
seat other than the child occu-
pant and a child restraint system.
. Do not place more than one child
on the seat.
. Do not install any accessory
such as a table or TV onto theseatback.
. 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 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)
1. Turn the ignition switch to the “LOCK ”
position. 
2. Remove the child restraint system 
from the seat.

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 corre ctive 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 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 frontpassenger ’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 ”
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 ”
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. ! Effect vehicle modifications made

&System operation
CAUTION
Do not touch the SRS airbag system 
components with bare hands right
after deployment. Doing so can
cause burns because the compo-
nents can be very hot as a result ofdeployment.
The SRS airbags can function only when
the ignition switch is in the “ON ”position.
When the SRS airbag(s) deploy(s), 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. !
SUBARU advanced frontal airbagoperation
1) Driver ’s side
2) Passenger ’s side
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 inside both front 
fenders and the impact sensors in the
airbag control module detect a predeter-
mined 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 passen-
ger ’s modules) instructing the module(s)
to inflate the SRS frontal airbag(s). Thedriver ’s and front passenger ’s SRS frontal
airbags use dual stage inflators. The two
inflators of each airbag are triggered either
sequentially or simultaneously, depending
on the severity of impact in the case of thedriver ’s SRS frontal airbag and depending
on the severity of impact and the total load
on the seat in the case of the frontpassenger ’s SRS frontal airbag.
After deployment, the SRS airbag imme-
diately starts to deflate so that the driver ’s
vision is not obstructed and the driver ’s
ability to maintain control of the vehicle is

! Examples of the types of accidents 
in which the SRS side airbag and
SRS curtain airbag will basically not
deploy.
1) The vehicle is involved in frontal collision
with another vehicle (moving or station- ary). 2) The vehicle is struck from behind. 
3) The vehicle pitches end over end.
In the event of accidents like those 
illustrated, the SRS side airbag and SRS 
curtain airbag are basically not designed 
to deploy.
1) First impact 
2) Second impact
A) SRS curtain airbag 
B) SRS side airbag
In an accident where the vehicle is struck 
from the side more than once, the SRS
side airbag and SRS curtain airbag deploy
only once on the first impact. 
Example: In the case of a double side 
impact collision, first with one vehicle and
immediately followed by another from the
same direction, once the SRS side airbag and SRS curtain airbag are activated on
the first impact, they will not be activated
on the second. &

WARNING
If the warning light exhibits any of 
the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system. Immediately take your vehi-
cle to your nearest SUBARU dealer
to have the system checked. Unless 
checked and properly repaired, the 
seatbelt pretensioners and/or SRS
airbags will operate improperly (e.g.
SRS airbags may inflate in a very
minor collision or not inflate in a
severe collision), which may in-
crease the risk of injury. . Flashing or flickering of the warn-
ing light
. No illumination of the warning
light when the ignition switch is 
first turned to the “ON ”position
. Continuous illumination of the
warning light
. Illumination of the warning light while driving
& SRS airbag system servicing
WARNING
. When discarding an airbag mod-
ule or scrapping the entire vehi- 
cle damaged by a collision, con-
sult your SUBARU dealer.
. The SRS airbag has no user-
serviceable parts. Do not use 
electrical test equipment on any 
circuit related to the SRS airbag
system. For required servicing of
the SRS airbag, consult your
nearest SUBARU dealer. Tamper-
ing with or disconnecting thesystem ’s wiring could result in
accidental inflation of the SRS
airbag or could make the system
inoperative, which may result in
serious injury.

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
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. 
To make replacement keys, the security ID

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“ Ignition switch ”F 3-3.
