2006 SUBARU LEGACY Owners Manual

1-56 Seat, seatbelt and SRS airbags
TOperation
The SRS side airbag and SRS curtain air-
bag can function only when the ignitionswitch is in the “ON” position.
The driver’s and front passenger’s SRS
side airbags and SRS curtain airbags de-
ploy 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 sensory 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 location
could be propelled through the
cabin with great force by the cur-
tain airbag, or it could prevent
correct deployment of the curtain
airbag. In either case, the result
could be serious injuries.
yDo 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 air-
bags, they could cause serious in-
juries by coming off the coat
hooks and being thrown through
the cabin or by preventing deploy-
ment 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 hangers.
Do not put any kind of cover or
clothes or other objects over either
front seatback and do not attach la-
bels or stickers to the front seat sur-
face on or near the SRS side airbag.
They could prevent proper deploy-
ment of the SRS side airbag, reduc-
ing protection available to the front
seat’s occupant.

senses 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. If it is a rear wheel
house impact sensor alone that senses a
sufficiently strong impac
t force, the control
module causes only the SRS curtain air-
bag on the impacted side to inflate. After
the deployment, the SRS side airbag im-
mediately starts to deflate. The time re-
quired from detection of an impact to de-
flation of an SRS side airbag after deploy-
ment 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 air-
bag deploy even when no one occupies
the seat on the side on which an impact is
applied.
When the SRS side airbag and SRS cur-
tain airbag deploy, a sudden, fairly loud in-
flation noise will be heard and some
smoke will be released. These occurrenc-
es are a normal result of the deployment.
This smoke does not indicate a fire in the vehicle.
The SRS side airbag and SRS curtain air-
bag are designed to deploy in the event of
an accident involving a moderate to se-
vere side impact collision. It is basically
not designed to deploy in a lesser side im-
pact. 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 it-self. V
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.
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 sys-
tem (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.

1) The vehicle is involved in an oblique side-on impact.
2) The vehicle is involved in a side-on
impact in an area outside the vicinity
of the passenger compartment.
3) The vehicle strikes a telephone pole
or similar object.
4) The vehicle is involved in a side-on impact from a motorcycle.
5) The vehicle rolls onto its side or roof.
There are many types of collisions which
might not necessarily require SRS side
airbag and SRS curtain airbag deploy-
ment. In the event of accidents like those
illustrated, the SRS side airbag and SRS
curtain airbag may not deploy depending
on the level of accident forces involved.

Examples of the types of accidents
in which the SRS side airbag and
SRS curtain airbag will basically not
deploy.
1) The vehicle is involved in frontal collision with another vehicle (moving or station- ary).
2) The vehicle is struck from behind.
The SRS side airbag and SRS curtain air-
bag are basically not designed to deploy if
the vehicle is involved in a frontal collision
or is struck from behind. Examples of such
accidents are illustrated.
1) First impact
2) Second impact
A) SRS curtain airbag
B) SRS side airbag
In an accident where the vehicle is struck
from the side more than once, the SRS
side airbag and SRS curtain airbag deploy
only once on the first impact.
Example: In the case of a double side im-
pact collision, first with one vehicle and immediately followed by another from the
same direction, once the SRS side airbag
and SRS curtain airbag are activated on
the first impact, they will not be activated
on the second. „
SRS airbag system monitors
A diagnostic system continually monitors
the readiness of the SRS airbag system
(including front seatbelt pretensioners)
while the vehicle is being driven. The SRS
airbag system warning light “AIRBAG” will
show normal system operation by lighting
for approximately 6 seconds when the ig-
nition switch is turned to the “ON” position.
The following components are monitored
by the indicator: y Front sub sensor (Right-hand side)

If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt pre-
tensioners and/or SRS airbag sys-
tem. Immediately take your vehicle
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 mi-
nor collision or not inflate in a se-
vere collision), which may increase
the risk of injury.
yFlashing or flickering of the warn-
ing light
yNo illumination of the warning
light when the ignition switch is first turned to the “ON” position
yContinuous illumination of the
warning light
yIllumination of the warning light

yWhen discarding an airbag mod-
ule or scrapping the entire vehicle
damaged by a collision, consult
your SUBARU dealer.
yThe SRS airbag has no user-ser-
viceable parts. Do not use electri-
cal 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 discon-
necting the system’s wiring could
result in accidental inflation of the
SRS airbag or could make the sys-
tem inoperative, which may result
in serious injury. The wiring har-
nesses of the SRS airbag system
are covered with yellow insulation
and system connectors are yellow
for easy identification.

In the event that the SRS airbag is de-
ployed, replacement of the system
should be performed only by an autho-
rized SUBARU dealer. When the com-
ponents of the SRS airbag system are
replaced, use only genuine SUBARU parts.
NOTE
In the following cases, contact your
SUBARU dealer as soon as possible. y
The front part of the vehicle was in-
volved 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.y The pad of the steering wheel, the
cover over the front passenger’s SRS
frontal airbag, or either roof side (from
the front pillar to a point over the rear
seat) is scratched, cracked, or other-
wise damaged.y Either center pillar and rear wheel
house or a nearby area of the vehicle
was involved in an accident in which
the SRS side airbag and SRS curtain
airbag did not deploy. y The fabric or leather of either front
seatback is cut, frayed, or otherwise
damaged. „
Precautions against vehicle
modificationIf you need service or repair in areas
listed in the following, have an au-
thorized SUBARU dealer perform
the work. The SRS airbag control
module, impact sensors and airbag
modules are stored in these areas. yUnder the center console
