warning light will illuminate. Have the
system inspected by your SUBARU deal-
er immediately if the SRS airbag system
warning light illuminates.
If your vehicle has sustained impact, this
may affect the proper function of the
SUBARU advanced frontal airbag system.
Have your vehicle inspected at your
SUBARU dealer. NOTE
The front passenger ’s SRS side airbag,
SRS curtain airbag and seatbelt pre-
tensioner are not controlled by the
SUBARU advanced frontal airbag sys-tem. ! Passenger ’s frontal airbag ON and
OFF indicators
Refer to “Front passenger ’s frontal airbag
ON and OFF indicators ”F 3-16.
! 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 that follows.) .
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.
When the front passenger ’s seat is occu-
pied 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 ’sSRS
frontal airbag even though that seat is
occupied by a child. . Do not place any article on the seat
other than the child occupant 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 the seatback.. Do not store a heavy load in the
seatback pocket.. Do not allow the rear seat occupant 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)
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

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 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.
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
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

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.

!Example of accident in which the driver ’s/driver ’s and front passen-
ger ’s SRS frontal airbag(s) will most
likely deploy.
A head-on collision against a thick con-
crete wall at a vehicle speed of 12 to 19
mph (20 to 30 km/h) or higher activates
only the driver ’s SRS frontal airbag or both
driver ’s and front passenger ’s SRS frontal
airbags. The airbag(s) will also be acti-
vated when the vehicle is exposed to a
frontal impact similar in fashion and
magnitude to the collision describedabove. !
Examples of the types of accidents
in which it is possible that thedriver ’s/driver ’s and front passen-
ger ’s SRS frontal airbag(s) will de-
ploy.
Only the driver ’s SRS frontal airbag or
both driver ’s and front passenger ’s SRS
frontal airbags may be activated when the
vehicle sustains a hard impact in the
undercarriage area from the road surface
(such as when the vehicle plunges into a
deep ditch, is severely impacted or
knocked hard against an obstacle on the
road such as a curb). Seat, seatbelt and SRS airbags

! Examples of the types of accidents in which deployment of the driver ’s/driver ’s
and front passenger ’s SRS frontal airbag(s) is unlikely to occur.
1) The vehicle strikes an object, such as a
telephone pole or sign pole.
2) The vehicle slides under the load bed of a truck.
3) The vehicle sustains an oblique offset frontal impact.
4) The vehicle sustains an offset frontal collision.
5) The vehicle strikes an object that can move or deform, such as a parked vehicle.
There are many types of collisions which
might not necessarily require deployment
of driver ’s/driver ’s and front passenger ’s
SRS frontal airbag(s). In the event of
accidents like those illustrated, the dri-ver ’s/driver ’s and front passenger ’s SRS
frontal airbag(s) may not deploy depend-
ing on the level of accident forces in-volved.

!Examples of the types of accidents
in which the driver ’s/driver ’s and
front passenger ’s SRS frontal
airbag(s) will basically not deploy.
The driver ’s and front passenger ’s SRS
frontal airbags are designed basically not to deploy if the vehicle is struck from the
side or from behind, or if it rolls onto its
side or roof, or if it is involved in a low-
speed frontal collision.
1) First impact
2) Second impact
In an accident where the vehicle is
impacted more than once, the driver ’s
and/or front passenger ’s SRS frontal
airbag(s) will deploy only once on the firstimpact.
Example: In the case of a double collision,
first with another vehicle, then against a
concrete wall in immediate succession,
once either or both of the driver ’s and front
passenger ’s SRS frontal airbags is/are
activated on the first impact, it/they will not
be activated on the second impact. &
SRS side airbag and SRS
curtain airbag
The SRS side airbag is stored in the door
side of each front seat seatback, which
bears an “SRS AIRBAG ”label.
Inamoderatetoseveresideimpact
collision, the SRS side airbag on the
impacted side of the vehicle deploys
between the occupant and the door panel
and supplements the seatbelt by reducing
the impact on the occupant ’s chest and
waist. The SRS side airbag operates only
for front seat occupants.
The SRS curtain airbag on each side of
the cabin is stored in the roof side
(between the front pillar and a point over
the rear seat). An “SRS AIRBAG ”mark is
located at the top of each center pillar.
Inamoderatetoseveresideimpact
collision, the SRS curtain airbag on the
impacted side of the vehicle deploys
between the occupant and the side
window and supplements the seatbelt by
reducing the impact on the occupant ’s
head.
WARNING
The SRS side airbag and SRS
curtain airbag are designed as only
a supplement to the primary protec-
tion provided by the seatbelt. They Seat, seatbelt and SRS airbags

1-50Seat, seatbelt and SRS airbags
do not do away with the need to
fasten seatbelts. It is also important
to wear your seatbelt to help avoid
injuries that can result when an
occupant is not seated in a proper
upright position.
WARNING
. Do not sit or lean unnecessarily
close to either front door. The
SRS side airbag is stored in both
front seat seatbacks next to the
door, and it provides protection
by deploying rapidly (faster than
the blink of an eye) in the event of
a side impact collision. However,
theforceofSRSsideairbag
deployment may cause injuries if your head or other parts of the
body are too close to the SRS
side airbag.
. Since your vehicle is equipped
with SRS curtain airbags, do not
sit or lean unnecessarily close to
the front or rear door on either
side. Also, do not put your head,
arms and hands out of the win-
dow. The SRS curtain airbag on
each side of the cabin is stored in
the roof side (between the front
pillar and a point over the rear
seat), and it provides protection
by deploying rapidly (faster than
the blink of an eye) in the event of
a side impact. However, the force
of its deployment may cause
injuries if your head is too close
to it.
WARNING
Do not rest your arm on either front
door or its internal trim. It could be
injured in the event of SRS side
airbag deployment.

WARNING
. Never allow a child to kneel on
the front passenger ’s seat facing
the side window or to wrap his/
her arms around the front seat
seatback. In the event of an
accident, the force of the SRS
side airbag deployment could
injure the child seriously be-
cause his/her head or arms or
other parts of the body are too
close to the SRS side airbag.
Since your vehicle is also
equipped with a front passen-ger ’s SRS frontal airbag, children
aged 12 and under should be
placed in the rear seat anyway
and should be properly re-
strained at all times.
. Never allow a child to kneel on
any passenger ’s seat facing the
side window or put their head,
arms and hands out of the win-
dow. In the event of an accident,
the force of the SRS curtain
airbag deployment could injure
the child seriously because his/
her head is close to the SRS
curtain airbag.
WARNING
. Do not attach accessories to the
door trim or near either SRS side
airbags and do not place objects
near the SRS side airbags. In the
event of the SRS side airbag
deployment, they could be pro-
pelled dangerously toward thevehicle ’s occupants and cause
injuries.
. Do not attach a hands-free micro-
phone or any other accessory to
a front pillar, a center pillar, a rear
pillar, the windshield, a side win-
dow, an assist grip, or any other
cabin surface that would be near
a deploying SRS curtain airbag.
