Seat, seatbelt and SRS airbags
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 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 impactIn 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 airbagThe 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.

Seat, seatbelt and SRS airbags
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. 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 the
vehicle ’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.Seat, seatbelt and SRS airbags

Seat, seatbelt and SRS airbags
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.
. Do not hang coat hangers or
other hard or pointed objects on
the coat hooks. If such items
were hanging on the coat hooks
during deployment of the SRS
curtain airbags, they could cause
serious injuries by coming off the
coat hooks and being thrown
through the cabin or by prevent-
ing deployment of the curtain
airbags.
Before hanging clothing on the
coat hooks, make sure there are
no sharp objects in the pockets.
Hang clothing directly on the
coat hooks without using hang-
ers.
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 is located in each of the
left and right center pillars and rear wheel
houses. If a center pillar impact sensor
senses an impact force above a prede-

Black plate (85,1)
北米Model "A2420BE-B" EDITED: 2006/ 7/ 26
termined 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 it is a rear
wheel house impact sensor alone that
senses a sufficiently strong impact force,
the control module causes only the SRS
curtain airbag on the impacted side to
inflate. 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
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 to deploy in the event
of an accident involving 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 and SRS curtain airbag
deployment would not help the occupant
in those situations.
Each SRS side airbag and SRS curtain
airbag are designed to function on a one-
time-only basis.
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 and SRS
curtain airbag will most likely de-
ploy.
A severe side impact near the front seat
activates the SRS side airbag and SRS
curtain airbag.

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.

& SRS airbag system servicing
WARNING
. When discarding an airbag mod-
ule or scrapping the entire vehi-
cle damaged by a collision,
consult 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, see your nearest
SUBARU dealer. Tampering with
or disconnecting the system ’s
wiring could result in accidental
inflation of the SRS airbag or
could make the system inopera-
tive, which may result in serious
injury. The wiring harnesses of
the SRS airbag system are cov-
ered with yellow insulation and
system connectors are yellow for
easy identification.
CAUTION
If you need service or repair in areas
listed in the following, have an
authorized SUBARU dealer perform
the work. The SRS airbag control
module, impact sensors and airbag
modules are stored in these areas.
. Under the center console
. Inside each front fender
. Steering wheel and column and
nearby areas
. Top of the dashboard on front
passenger ’s side and nearby
areas
. Each front seat and nearby area
. Inside each center pillar
. In each roof side (from the front
pillar to a point over the rear seat)
. Between the rear seat cushion
and rear wheel house on each
side
In the event that the SRS airbag is
deployed, replacement of the system
should be performed only by an author-
ized SUBARU dealer. When the compo-
nents of the SRS airbag system are
replaced, use only genuine SUBARU
parts.
NOTEIn the following cases, contact your
SUBARU dealer as soon as possible.
. The front part of the vehicle was
involved in an accident in which the
only the driver ’s SRS frontal airbag or
both driver ’s and front passenger ’s
SRS frontal airbags did not deploy.
