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 deploy- ment, the SRS airbag immediately starts
to deflate so that the driver
’s vision is not
obstructed. The time required from detect-
ing 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.

!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.
In a rollover, SRS curtain airbags on both
sides of the vehicle deploy between the
occupant and the side window and sup-
plement the seatbelt by reducing the
impact to 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
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 or a rollover. How-
ever, 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.

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. In addition, a rollover sensor
is located inside the airbag control mod-
ule. If one of the center pillar impact
sensors and the impact sensor that is
located under the rear center seat to-
gether 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 a suffi-
ciently strong impact force, the control
module causes only the SRS curtain
airbag on the impacted side to inflate. If
the rollover sensor detects rollover of the
