. It is possible to cancel the warning
operation that follows the 6-second
warning after turning ON the ignition
switch. When the ignition switch is
turned ON next time, however, the
complete sequence of the warning
operation resumes. For further details
about canceling the warning operation,
please contact your SUBARU dealer.
If there is no passenger on the front
passenger ’s seat, the seatbelt warning
device for the front passenger ’s seat will
be deactivated. The front passenger ’s
occupant detection system monitors
whether or not there is a passenger on
the front passenger ’s seat.
Observe the following precautions. Failure
to do so may prevent the device from
functioning correctly or cause the device
to fail.
. Do not install any accessory such as a
table or TV onto the seatback.
. Do not store a heavy load in the
seatback pocket.
. Do not allow the rear seat occupant to
place his/her hands or legs on the front
passenger ’s seatback, or allow him/her to
pull the seatback.
. Do not use front seats with their back-
ward-forward position and seatback not
being locked into place securely. If any of them are not locked securely, adjust them
again. For adjusting procedure, refer to
the
“Manual seat ”in the front seats section
in Chapter 1 in this owner ’s manual.
(Models equipped with manual seats only)
If the seatbelt warning device for the front
passenger ’s seat does not function cor-
rectly (e.g., it is activated even when the
front passenger ’s seat is empty or it is
deactivated even when the front passen-
ger has not fastened his/her seatbelt),
take the following actions.
. Ensure that no article is placed on the
seat other than a 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. (Models
equipped with manual seats only)
If the seatbelt warning device for front
passenger ’s seat still does not function
correctly after taking relevant corrective
actions described above, immediately
contact your SUBARU dealer for an
inspection.
& Fastening the seatbelt
WARNING
. Never use a belt that is twisted or
reversed. In an accident, this can
increase the risk or severity of
injury.
. Keep the lap belt as low as
possible on your hips. In a colli-
sion, this spreads the force of the
lap belt over stronger hip bones
instead of across the weaker
abdomen.
. Seatbelts provide maximum re-
straint when the occupant sits
well back and upright in the seat.
To reduce the risk of sliding
under the seatbelt in a collision,
the front seatbacks should be
always used in the upright posi-
tion while the vehicle is running.
If the front seatbacks are not
used in the upright position in a
collision, the risk of sliding under
the lap belt and of the lap belt
sliding up over the abdomen will
increase, and both can result in
serious internal injury or death.
. Do not put cushions or any other
materials betwe en occupants
and seatbacks or seat cushions.

& System monitorsSRS airbag system warning light (Turbo
models)
SRS airbag system warning light (Non-
turbo models)A diagnostic system continually monitors
the readiness of the seatbelt pretensioner
while the vehicle is being driven. The
seatbelt pretensioners share the control
module with the airbag system. Therefore,
if any malfunction occurs in a seatbelt
pretensioner, the SRS airbag system
warning light will illuminate. The SRS
airbag system warning light will show
normal system operation by lighting for
approximately 6 seconds when the igni-
tion switch is turned to the “ON”position.

Seat, seatbelt and SRS airbags
! Operation1) Driver ’s side
2) Passenger ’s sideThe 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 front
passenger
’s SRS frontal airbag depend-
ing on the total load on the front passen-
ger ’s seat monitored by the front
passenger ’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). 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 simultaneously, 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 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.

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.

WARNING
If the warning light exhibits any of
the following conditions, there may
be a malfunction in the seatbelt
pretensioners and/or SRS airbag
system. Immediately take your vehi-
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.
