1-40Seat, seatbelt and SRS airbags
WARNING
Never hold a child on your lap or in
your arms. The SRS airbag deploys
with considerable force and can
injure or even kill the child.WARNING
The SRS airbag deploys with con-
siderable speed and force. Occu-
pants who are out of proper position
when the SRS airbag deploys could
suffer very serious injuries. Be-
cause the SRS airbag needs enough
space for deployment, the driver
should always sit upright and well
back in the seat as far from the
steering wheel as practical while
still maintaining full vehicle control
and the front passenger should
move the seat as far back as
possible and sit upright and well
back in the seat.
It is also important to wear your seatbelt to help avoid injuries that
can result when the SRS airbag
contacts an occupant not in proper
position such as one thrown toward
the front of the vehicle during pre-
accident braking.
WARNING
Do not put any objects over the
steering wheel pad and dashboard.
If the SRS frontal airbag deploys,
those objects could interfere with its
proper operation and could be pro-
pelled inside the vehicle and cause
injury.

WARNING
Do not attach accessories to the
windshield, or fit an extra-wide mir-
ror over the rear view mirror. If the
SRS airbag deploys, those objects
could become projectiles that could
seriously injure vehicle occupants.
! Driver ’s SRS frontal airbag
The driver ’s SRS frontal airbag uses a
dual stage inflator. The inflator operates in
different ways depending on the severity
of impact, backward-forward adjustment
of the driver ’s seat position and whether or
not he/she is wearing the seatbelt.
The backward-forward adjustment of the driver ’s seat position is monitored by the driver
’s seat position sensor under the
driver ’s seat.
Whether or not the driver is wearing the
seatbelt is monitored by the seatbelt
buckle switch.
Observe the following precautions. Failure
to do so may cause the seatbelt buckle
switch and/or the seat position sensor to
malfunction, preventing the Subaru ad-
vanced frontal airbag system from func-
tioning correctly or causing the system tofail. . Do not place articles/metal objects or
install any accessory other than a genuine
SUBARU accessory under the driver ’s
seat. Do not allow the rear seat occupant
to kick the driver ’s seat or push up its
bottom surface with his/her feet. . Do not place a magnet near the
seatbelt buckle or under the driver ’s seat.
If the seatbelt buckle switch and/or the driver ’s seat position sensor have failed,
the SRS airbag system warning light will
illuminate. Although the driver ’sSRS
frontal airbag can deploy regardless of
the backward-forward adjustment of the
driver ’s seat position even when the
warning light is on, have the system
inspected by your SUBARU dealer im-
mediately if the SRS airbag system warn-
ing light comes on. NOTE
The driver
’s SRS side airbag and
seatbelt pretensioner are not controlled
by the Subaru advanced frontal airbagsystem. ! Front passenger ’s SRS frontal air-
bag
The front passenger ’s SRS frontal airbag
uses a dual stage inflator. The inflator
operates in different ways depending on
the severity of impact.
The total load on the seat is monitored by
the occupant detection system ’s weight
sensor located under the seat.
The system has another sensor that
monitors the tension of the front passen-
ger seatbelt. Using the total seat load and
seatbelt tension data from the sensors,
the occupant detection system determines
whether the front passenger ’s SRS frontal
airbag should or should not be inflated.
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.
Observe the following precautions. Failure
to do so may prevent the Subaru ad-
vanced frontal airbag system from func-
tioning correctly or cause the system to fail. Seat, seatbelt and SRS airbags

. Do not apply any strong impact to the
front passenger ’s seat such as by kicking.
. Do not spill liquid on the front passen-
ger ’s seat. If liquid is spilled, 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 accessory under the front pas-senger ’s seat.
. Do not place anything (shoes, umbrel-
la, etc.) under the front passenger ’s seat.
. The front passenger ’s seat must not be
used with the head restraint removed. . Do not leave any article including a
child restraint system on the front passen- ger ’s seat or the seatbelt tongue and
buckle engaged when you leave yourvehicle. . Do not place a magnet near the
seatbelt buckle and the seatbelt retractor.. 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 tothe “Front seats ”section in this chapter.
. If you use an optional seatbelt exten-
der, remove it after each use. (Refer to the“ Seatbelt extender ”section in this chap- ter.)
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 comes on.
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.
NOTE
The front passenger ’s SRS side airbag
and seatbelt pretensioner are not con-
trolled by the Subaru advanced frontal
airbag system. !
Passenger ’s frontal airbag ON and
OFF indicators
ON or: Front passenger ’s frontal airbag
ON indicator
or: Front passenger ’s frontal airbag
OFF indicator
The front passenger ’s frontal airbag ON
and OFF indicators show you the status of
the front passenger ’s SRS frontal airbag.
The indicators are located next to the
clock in the center portion of the dash-board.
When the ignition switch is turned to the “ ON ”position, both the ON and OFF
indicators illuminate for 6 seconds during
which time the system is checked. Follow-
ing the system check, both indicators
extinguish for 2 seconds. After that, one
of the indicators illuminates depending on

the status of the front passenger’s SRS
frontal airbag determined by the Subaru
advanced frontal airbag system monitor-ing.
If the front passenger ’s SRS frontal airbag
is activated, the passenger ’s frontal airbag
ON indicator will illuminate while the OFF
indicator will remain extinguished.
If the front passenger ’s SRS frontal airbag
is deactivated, the passenger ’s frontal
airbag ON indicator will remain extin-
guished while the OFF indicator willilluminate.
With the ignition switch turned to the “ON ”
position, if both the ON and OFF indica-
tors remain lit or extinguished simulta-
neously even after the system check
period, the system is faulty. Contact your
SUBARU dealer immediately for an in-spection. ! Conditions in which front passen- ger’s SRS frontal airbag is not
activated
The front passenger ’s SRS frontal airbag
will not be activated when any of the
following conditions are met regarding the
front passenger ’s seat:
. The seat is empty.
. The seat is equipped with a rearward
facing child restraint system and an infant
is restrained with it. (See WARNING that follows.) .
The seat is equipped with a forward
facing child restraint system and a small
child is restrained with it. (See WARNING
that follows.) . The seat is equipped with a booster
seat and a small child is in the booster
seat. (See WARNING that follows.) . The seat is relieved of the occupant
load for a time exceeding the predeter-
mined monitoring time period. . The seat is occupied by a child who
has outgrown a child restraint system
(See WARNING that follows.) or by a
small adult. . The front passenger ’s occupant detec-
tion system is faulty.
WARNING
NEVER INSTALL A REARWARD FA-
CING CHILD SEAT IN THE FRONT
PASSENGER ’S SEAT EVEN IF THE
FRONT PASSENGER ’S SRS FRON-
TAL AIRBAG IS DEACTIVATED. Be
sure to install it in the REAR seat in
a correct manner. Also, it is strongly
recommended that any forward fa-
cing child seat or booster seat be
installed in the REAR seat, and that
even children who have outgrown a
child restraint system be also seated in the REAR seat. This is
because children sitting in the frontpassenger
’s seat may be killed or
severely injured should the frontpassenger ’s SRS frontal airbag de-
ploy. REAR seats are the safest
place for children.
When the front passenger ’s seat is occu-
pied by a child, observe the following
precautions. Failure to do so may increase
the load on the front passenger ’s seat,
activating the front passenger ’sSRS
frontal airbag even though that seat is
occupied by a child. . Do not place any article on the seat
other than the child occupant and a child
restraint system. . Do not place more than one child on
the seat.. 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. Seat, seatbelt and SRS airbags

Turntheignitionswitchtothe “OFF ”
position if the front passenger ’s frontal
airbag ON indicator illuminates and the
OFF indicator extinguishes even when an
infant or a small child is in a child restraint
system (including booster seat). Remove
the child restraint system from the seat. By
referring to the child restraint manufac-turer ’s recommendations as well as the
child restraint system installation proce-
dures in the “Child restraint systems ”
section in this chapter, correctly install
the child restraint system. Turn the ignition
switch to the “ON ”position and make sure
that the front passenger ’s frontal airbag
ON indicator goes out and the OFF
indicator comes on.
If still the ON indicator remains illuminated
while the OFF indicator extinguishes, 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 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.
If the ON indicator still illuminates while
the OFF indicator extinguishes after taking
relevant corrective actions described
above, relocate the child restraint system
to the rear seat and immediately contact
your SUBARU dealer for an inspection.
NOTE
When 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. If the front passenger ’s SRS
frontal airbag is activated (the ON
indicator illuminates while the OFF
indicator extinguishes), take the follow-
ing actions. . Ensure that no article is placed on
the seat other than the occupant. . Ensure that there is no article left in
the seatback pocket.
If the ON indicator still illuminates while
the OFF indicator extinguishes despite
the fact that the actions noted above have been taken, seat the child/small
adult in the rear seat and immediately
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 a heavy article is placed on the
seat.
When the front passenger ’s seat is occu-
pied by an adult, observe the following
precautions. Failure to do so may lessen
the load on the front passenger ’s seat,
deactivating the front passenger ’s SRS
frontal airbag despite the fact that the seat
is occupied by an adult. . Do not allow the rear seat occupant to

lift the front passenger’s seat cushion
using his/her feet. . Do not place any article under the front
passenger ’s seat, or squeeze any article
from behind and under the seat. This may
lift the seat cushion. . Do not squeeze any article between
the front passenger ’s seat and side trim/
pillar, door or center console box. This
may lift the seat cushion. ! If the passenger ’s frontal airbag OFF

indicator extinguishes even when
the front passenger ’s seat is occu-
pied by an adult
This can be caused by the adult incor-
rectly sitting in the front passenger ’s seat.
Turntheignitionswitchtothe “OFF ”
position. Ask the front passenger to set
the seatback to the upright position, sit up
straight in the center of the seat cushion,
correctly fasten the seatbelt, position his/
her legs out forward, and adjust the seat to
the rearmost position. Turn the ignition
switch to the “ON ”position. If the OFF
indicator remains illuminated while the ON
indicator remains extinguished, take the
following actions. . Turn the ignition switch to the “OFF ”
position.. Ensure that there are no articles, books, shoes, or other objects trapped
under the seat, at the rear of the seat, or
on the side of the seat. .
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. . Next, turn the ignition switch to the
“ ON ”position and wait 6 seconds to allow
the system to complete self-checking.
Following the system check, both indica-
tors extinguish for 2 seconds. Now, the
ON indicator should illuminate while the
OFF indicator remains extinguished.
If the OFF indicator still illuminates while
the ON indicator remains extinguished,
ask the occupant to move to the rear seat
and immediately contact your SUBARU
dealer for an inspection. ! Effect vehicle modifications made

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 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 frontpassenger ’s SRS frontal airbag depend-
ing on the total load on the front passen-ger ’s seat monitored by the front passen-
ger ’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). Thedriver ’s and front passenger ’s SRS frontal
airbags use dual stage inflators.
The two inflators of each airbag are
triggered either sequentially or simulta-
neously, 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 de-
pending on the severity of impact and the total load on the seat in the case of the
front passenger
’s SRS frontal airbag. After
deployment, the SRS airbag immediately
starts to deflate so that the driver ’s vision
is not obstructed. The time required from
detecting 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.
CAUTION
Do not touch the SRS airbag system
components around the steering
wheel and dashboard with bare hands right after deployment. Doing
so can cause burns because the
components can be very hot as a
result of deployment.
The driver ’s SRS frontal airbag and front
passenger ’s SRS frontal airbag are de-
signed to deploy in the event of an
accident involving a moderate to severe
frontal collision. It is basically not designed
to deploy in lesser frontal impacts be-
cause the necessary protection can be
achieved by the seatbelt alone. Also, they
are basically not designed to deploy in
side or rear impacts or in roll-over acci-
dents because deployment of only thedriver ’s SRS frontal airbag or both driver ’s
and front passenger ’s SRS frontal airbags
would not help the occupant in those
situations. The driver ’s and front passen-
ger ’s SRS frontal airbags are designed to
function on a one-time-only basis.
SRS airbag deployment depends on the
level of force experienced in the passen-
ger compartment during a collision. That
level differs from one type of collision to
another, and it may have no bearing on
the visible damage done to the vehicleitself. Seat, seatbelt and SRS airbags
