Turntheignitionswitchtothe “OFF ”
position if the front passenger ’s frontal
airbag ON indicator illuminates and the
OFF indicator extinguishes 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 the “Child restraint systems ”
section in this chapter, correctly install
the child restraint system. Turn the ignition
switch to the “ON ”position and make sure
that the front passenger ’s frontal airbag
ON indicator goes out and the OFF
indicator comes on.
If still the ON indicator remains illuminated
while the OFF indicator extinguishes, 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 illuminates while
the OFF indicator extinguishes after taking
relevant corrective 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 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 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.
Turntheignitionswitchtothe “OFF ”
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 “OFF ”
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 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

Operation
A) Driver ’s side
B) Passenger ’s side
1) SRS AIRBAGs deploy as soon as a collision occurs.
2) After deployment, SRS AIRBAGs start to deflate immediately so that the driver ’s vision is not
obstructed.

The SRS airbag can function only when
the ignition switch is in the“ON ”position.
The Subaru advanced frontal airbag sys-
tem is designed to determine the activa-
tion or deactivation condition of the frontpassenger ’s SRS frontal airbag depend-
ing on the total load on the front passen-ger ’s seat monitored by the front passen-
ger ’s occupant detection system weight
sensor. For this reason, only the driver ’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 simulta-
neously, depending on the severity of
impact, backward-forward adjustment of
the driver ’s seat position and fastening/
unfastening of the seatbelt in the case of
the driver ’s SRS frontal airbag and de-
pending on the severity of impact and the total load on the seat in the case of the
front passenger
’s SRS frontal airbag. After
deployment, the SRS airbag immediately
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 shorter
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. Seat, seatbelt and SRS airbags

! 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).

!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.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). If the vehicle strikes
an object, such as a telephone pole or
sign pole, or if it slides under a truck ’s load
bed, or if it sustains an oblique offset
frontal impact, the driver ’s/driver ’sand
front passenger ’s SRS frontal airbag(s)
may not deploy depending on the level of
accident forces involved. !
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 Seat, seatbelt and SRS airbags
1-49

1-50Seat, seatbelt and SRS airbags
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
The SRS side airbag is stored in the door
side of each front seat seatback, which
bears an “SRS AIRBAG ”label.
In a moderate to severe side impact
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
head.
WARNING
The SRS side airbag is designed as
only a supplement to the primary
protection provided by the seatbelt.
They do not do away with the need
to fasten seatbelts. It is also impor-
tant 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, the force of SRS
side airbag deployment may cause
injuries if your head or other parts of
the body are too close to the SRS
side airbag.

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
because 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 apassenger
’s SRS frontal airbag,
children aged 12 and under should
be placed in the rear seat anyway
and should be properly restrained at
all times.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 Seat, seatbelt and SRS airbags

event of the SRS side airbag deploy-
ment, they could be propelled dan-
gerously toward the vehicle ’s occu-
pants and cause injuries.
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
1) SRS side airbag deploys as soon as a
collision occurs.
2) SRS side airbag protects the front passenger ’s head and chest.
3) After deployment, SRS side airbag starts to deflate immediately. The SRS side airbag can function only
when the ignition switch is in the
“ON ”
position.
The driver ’s and front passenger ’s SRS
side airbags deploy independently of each
other since each has its own impact
sensor. Also, the SRS side airbag deploys
independently of the frontal airbags in the
steering wheel and instrument panel.
An impact sensor is incorporated into
each of the vehicle ’s center pillars. If
either sensor detects a certain predeter-
mined amount of force during a side
impact collision, the control module sends
a signal to the side airbag module on the
impacted side of the vehicle, instructing it
to inflate the SRS side airbag. Then the
side airbag module produces gas, which
instantly inflates the SRS side airbag.
After deployment, the SRS side airbag
will deflate in a few seconds.
The SRS side airbag deploys even when
no one occupies the seat on the side on
which an impact is applied.
When the SRS side airbag deploys, a
sudden, fairly loud inflation noise will be
heard and some smoke will be released.
These occurrences are normal result of
the deployment. This smoke does not
indicate a fire in the vehicle.

CAUTION
Do not touch the SRS side airbag
system components around the
front seat seatback 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 side airbag is designed to
deploy in the event of an accident invol-
ving a moderate to severe side impact
collision. It is basically not designed to
deploy in a lesser side impact. Also, it is
basically not designed to deploy in frontal
or rear impacts because SRS side airbag
deployment would not help the occupant
in those situations.
Each SRS side airbag is designed to
function on a one-time-only basis.
SRS side airbag deployment depends on
the level of force experienced in the
passenger compartment during a side
impact collision. That level differs from
one type of collision to another, and it may
have no bearing on the visible damage
done to the vehicle itself. !
Example of the type of accident in
which the SRS side airbag will most
likely deploy.
A severe side impact near the front seat
activates the SRS side airbag. Seat, seatbelt and SRS airbags
