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 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 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 seatingposture. 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 action.
. Ensure that no article is placed on
the seat other than the occupant.
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 certain items (e.g. jug of water)
are placed on the seat.
!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. Make sure that the front passenger
does not use a blanket, seat cushion, seat
cover, seat heater or massager, etc.
1-52

3. If wearing excessive layers of clothing,
the front passenger should remove any
unnecessary items before sitting in the
front passenger’s seat, or should sit in a
rear seat.
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.

!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 airbags 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 characteristic of item
(s) or person on the front passenger ’s seat
monitored by the front passenger ’s occu-
pant detection system 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 following sensors 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).
. the front sub sensors
. the impact sensors in the airbag control
module
On the driver ’s side, the SRS knee airbag
also inflates with the SRS frontal airbag.
1-54

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 characteristic
of item(s) or person on the seat in the case
of the front passenger ’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
not impaired. 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.
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 as follows.
. to deploy in the event of an accident
involving a moderate to severe frontal
collision
. to function on a one-time-only basis
The driver ’s SRS frontal airbag and front
passenger ’s SRS frontal airbag are not
designed as follows.
. to deploy in most lesser frontal im-
pacts
*1
. to deploy in most side or rear impacts
or in most roll-over accidents*2
*1: Because the necessary protection can be
achieved by the seatbelt alone.
*2: Because deployment of only the driver ’s
SRS frontal airbag or both the driver ’s and front
passenger ’s SRS frontal airbags would not
protect the occupant in those situations.
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 vehicle
itself.
!Example of accident in which the
driver ’s/driver ’s and front pas-
senger ’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 described
above.!
Examples of the types of acci-
dents in which it is possible that
the driver ’s/driver ’s and front
passenger ’s SRS frontal
airbag(s) will deployOnly 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).
1-56

!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 occur1) 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 acci-
dents in which the driver ’s/dri-
ver ’s and front passenger ’s SRS
frontal airbag(s) are not de-
signed to deploy in most cases
The driver ’s and front passenger ’s SRS frontal airbags are not designed to deploy
in most of the following cases.
.
If the vehicle is struck from the side or
from behind
. If the vehicle rolls onto its side or roof
. If the vehicle 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 first
impact.
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
1-58

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.
In a moderate to severe side impact
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.
For Crosstrek models, in a rollover, SRS
curtain airbags on both sides of the
vehicle deploy between the occupant
and the side window and supplement the
seatbelt by reducing the impact to the
occupant ’s head.
In an offset frontal collision, SRS curtain
airbags on both sides of the vehicle
deploy between the occupant and the
side window and supplement the seatbelt
by reducing the impact to the occupant ’s
head and chest.
! Operation
The SRS side airbag and SRS curtain
airbag can function only when the ignition
switch is in the “ON”position.
The following airbags deploy indepen-
dently of each other since each has its
own impact sensor. .
Driver ’s SRS side airbag
. Front passenger ’s SRS side airbag
. SRS curtain airbag (right-hand side)
. SRS curtain airbag (left-hand side)
Therefore, they may not both deploy in the
same accident. Also, the SRS side airbag
and SRS curtain airbag deploys indepen-
dently of the driver ’s and front passen-
ger ’s SRS frontal airbags in the steering
wheel and instrument panel.
An impact sensor, which senses impact
force, is located in each of the following
locations.
. In the left and right front doors
. In the left and right center pillars
. In the left and right rear wheel houses
. Under the rear center seat
For Crosstrek models, a rollover sensor is
also located inside the airbag control
module.
If both of the following sensors together
sense an impact force above a predeter-
mined 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.
. the impact sensor that is located under the rear center seat
.
one of the center pillar impact sensors
or front door impact sensors
If both of the following sensors together
sense an impact force above a predeter-
mined level in a side collision, the control
module causes only the SRS curtain
airbag on the impacted side to inflate.
. the impact sensor that is located under
the rear center seat
. one of the rear wheel house impact
sensors
For Crosstrek models, if the rollover
sensor detects rollover of the vehicle, the
control module inflates the SRS curtain
airbags on both sides. At this time, the
driver ’
s and front passenger ’s seatbelt
pretensioners also operate at the same
time.
After the deployment, the SRS side airbag
immediately starts to deflate. The time
required from detection of an impact to
deflation of an SRS side airbag after
deployment is shorter than the blink of
an eye.
The SRS

curtain airbag remains inflated
for a while following deployment then
slowly deflates.
The SRS side airbag and SRS curtain

Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
airbag deploy even when no one occupies
the seat on the side on which an impact is
applied.
When the SRS side airbag and SRS
curtain airbag deploy, a sudden, fairly loud
inflation noise will be heard and some
smoke will be released. These occur-
rences are a normal result of the deploy-
ment. 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 of
deployment.
After deployment, do not touch any
part of the SRS curtain airbag
system (from the front pillar to the
part of the roof side over the rear
seat). Doing so can cause burns
because the components can be
very hot as a result of deployment.
The SRS side airbag and SRS curtain
airbag are designed as follows:
. to deploy in the event of an accident
involvingamoderatetosevereside impact collision
.
to function on a one-time-only basis.
The SRS side airbag and SRS curtain
airbag are not designed to deploy in the
following cases:
. in most lesser side impact
. in most frontal or most rear impacts
(because the SRS side airbag and SRS
curtain airbag deployment would not
protect the occupant in those situations)
For Crosstrek models, the SRS curtain
airbags are also designed to deploy when
the vehicle is in an extremely inclined
state such as during a rollover. They are
not designed to deploy in most lesser
inclined state.
SRS side airbag and SRS curtain airbag
deployment depend on the level of force
experienced in the passenger compart-
ment 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.
1) A severe side impact near the front seat.

!Examples of the types of acci-
dents in which the SRS curtain
airbag will most likely deploy.
Except Crosstrek models
1) A severe side impact near the front seat or the rear seat. 2) An offset frontal collision that is severe
enough to deploy the front airbag.
