. Do not remove or disassemble
the front passenger ’s seat.
. Do not install any accessory
(such as an audio amplifier) other
than a genuine SUBARU acces-
sory under the front passenger ’s
seat.
. Do not place anything (shoes,
umbrella, etc.) under the front
passenger ’s seat.
. Do not use the front passenger ’s
seat with the head restraint re-
moved.
. Do not leave any articles on the
front passenger ’s seat or the
seatbelt tongue and buckle en-
gaged when you leave your ve-
hicle.
. Do not put sharp object(s) on the
seat or pierce the seat uphols-
tery.
. Do not place a magnet near the
seatbelt buckle and the seatbelt
retractor.
. Do not use front seats with their
backward-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
“Manual seat ”F1-4
(models equipped with manual
seats only).
If the seatbelt buckle switch and/or front
passenger ’s occupant detection system
have failed, the SRS airbag system
warning light will illuminate. Have the
system inspected by your SUBARU deal-
er immediately if the SRS airbag system
warning light illuminates.
If your vehicle has sustained impact, this
may affect the proper function of the
SUBARU advanced frontal airbag system.
Have your vehicle inspected at your
SUBARU dealer. Do not use the front
passenger ’s seat while driving the vehicle
to your SUBARU dealer.
! Passenger ’s frontal airbag ON and
OFF indicators
Refer to “Front passenger ’s frontal airbag
ON and OFF indicators ”F 3-16.
! Occupant detection system
The occupant detection system sensor is
installed under the seat upholstery and
monitors the physique and posture of the
front passenger. Using this information, the occupant detection system determines
whether the front passenger
’s SRS frontal
airbag should be deployed or not.
If the front passenger ’s seat cushion is
wet, this may adversely affect the ability of
the system to determine deployment. If
the seat cushion is wet, the front passen-
ger should stop sitting on the front
passenger ’s seat. Wipe off liquid from
the seat immediately, let the seat dry
naturally and then check that the front
passenger ’s frontal airbag ON and OFF
indicators

work properly.

!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.

Seat, seatbelt and SRS airbags/*SRS airbag (Supplemental Restraint System airbag)
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.
In an offset frontal collision, SRS side
airbags and 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 and chest.
! 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.
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
. On both the right and left sides at the
front of the vehicle (front sub sensors)
Rollover sensor and frontal impact sensor
are located inside the airbag control
module which is located under the center
of the instrument panel.
If the impact sensor that is located under
the rear center seat and one of the center
pillar impact sensors or front door impact
sensors both 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 the impact sensor that is located under
the rear center seat and one of the rear
wheel house impact 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.
Even if a frontal collision occurs, both right
and left SRS side airbags and SRS curtain
airbags will deploy when the front sensor
and the control unit determine that the
impact results from an offset frontal colli-
sion.
The SRS side airbags and SRS curtain
airbags are designed to deploy when the
driver
’s SRS frontal airbag deploys or the
driver ’s and passenger ’s SRS frontal air-
bags deploy in a frontal collision, and also
when the system determines that the
collision is an offset frontal collision. The
SRS side airbags and SRS curtain air-
bags are basically designed not to deploy
in a frontal collision when the SRS frontal
airbags do not deploy or the system
determines that the collision is other than
an offset frontal collision.
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
1-62
