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.
The occupant detection system may not
inflate the front passenger’s SRS frontal
airbag even when the driver’s SRS frontal
airbag deploys. This is normal. In this
case, although the front passenger’s SRS
frontal airbag does not operate, the front
passenger’s seatbelt pretensioner oper-
ates with the driver’s seatbelt preten-
sioner. For details about the seatbelt
pretensioner, refer to“Front seatbelt pre-
tensioners”F1-17.
CAUTION
Observe the following precautions.
Failure to do so may prevent the
SUBARU advanced frontal airbag
system from functioning correctly
or cause the system to fail.
.Do not apply any strong impact to
the front passenger’s seat such
as by kicking.
.Do not let rear passengers rest
their feet between the front seat-
back and seat cushion.
.Do not spill liquid on the front
passenger’s seat. If liquid isspilled, wipe it off immediately.
.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 vehi-
cle.
.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 themagain. For adjusting procedure,
refer to“Manual seat”F1-4
(models equipped with manual
seats only).
SRS airbag system warning lightIf the seatbelt buckle switch and/or front
passenger’s occupant detection system
have failed, the SRS airbag system warn-
ing light will illuminate. Have the system
inspected by your SUBARU dealer imme-
diately 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.

.Do not place more than one infant
in the child restraint system.
!If the front passenger’s frontal
airbag ON indicator illuminates
and the OFF indicator turns off
even when an infant or a small
child is in a child restraint sys-
tem (including booster seat)
1. Turn the ignition switch to the“LOCK”/
“OFF”position.
2. Remove the child restraint system from
the seat.
3. By referring to the child restraint
manufacturer’s recommendations as well
as the child restraint system installation
procedures in“Child restraint systems”
F1-21, correctly install the child restraint
system.
4. Turn the ignition switch to the“ON”
position and make sure that the front
passenger’s frontal airbag ON indicator
turns off and the OFF indicator illuminates.
If still the ON indicator remains illuminated
while the OFF indicator turns off, take the
following actions.
.Ensure that no article is placed on the
seat other than the child restraint system
and the child occupant.
.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.
If the ON indicator still remains illuminated
while the OFF indicator turns off after
taking relevant corrective actions de-
scribed above, relocate the child restraint
system to the rear seat and immediately
contact your SUBARU dealer for an
inspection.
NOTEWhen a child who has outgrown a child
restraint system or a small adult is
seated in the front passenger’s seat,
the SUBARU advanced frontal airbag
system may or may not activate the
front passenger’s SRS frontal airbag
depending on the occupant’s seating
posture. Children should always wear a
seatbelt when sitting in the seat irre-
spective of whether the airbag is deac-
tivated or activated. If the front passen-
ger’s SRS frontal airbag is activated
(the ON indicator remains illuminated
while the OFF indicator turns off),
ensure that no article is placed on the
seat other than the occupant.
If the ON indicator still remains illumi-
nated while the OFF indicator turns off
despite the fact that the actions noted
above have been taken, seat the child/small adult in the rear seat and imme-
diately contact your SUBARU dealer for
an inspection. Even if the system has
passed the dealer inspection, it is
recommended that on subsequent trips
the child/small adult always take the
rear seat.
Children who have outgrown a child
restraint system should always wear the
seatbelt irrespective of whether the airbag
is deactivated or activated.
!Conditions in which front passen-
ger’s SRS frontal airbag is activated
The front passenger’s SRS frontal airbag
will be activated for deployment upon
impact when any of the following condi-
tions are met regarding the front passen-
ger’s seat.
.When the seat is occupied by an adult.
.When certain items (e.g. jug of water)
are placed on the seat.
