SRS Airbag (Supplemental Restraint System Airbag)
70■SUBARU Advanced Frontal
Airbag SystemThis vehicle is equipped with a SUBARU
advanced frontal airbag system that
complies with the new advanced frontal
airbag requirements in the amended
Federal Motor Vehicle Safety Standard
(FMVSS) No. 208.
The SUBARU advanced frontal airbag
system automaticall y determines the
deployment force of the driver’s SRS
frontal airbag at the time of deployment as
well as whether or not to activate the front
passenger’s SRS frontal airbag and, if
activated, the deployment force of the
SRS frontal airbag at the time of deploy-
ment.
This vehicle has warning labels on the
driver’s and front passenger’s sun visors beginning with th
e phrase “EVEN WITH
ADVANCED AIR BAGS” and a tag
attached to the glove box lid beginning
with the phrase “Even with Advanced Air
Bags”. Make sure that you carefully read
the instructions on the warning labels and
tag.
Always wear your seatbelt. The SUBARU
advanced frontal airbag system is a
supplemental restraint system and must
be used in combination with a seatbelt. All
occupants should wear a seatbelt or be
seated in an appropriate child restraint
system.
For the locations of the SRS airbags, refer
to "Components" P68.
In a moderate to severe frontal collision,
the following components deploy.
 SRS frontal airbag for driver
 SRS frontal airbag for front passenger
 SRS curtain airbag*
 SRS knee airbag for driver
*: When an offset frontal collision that is
severe enough to deploy the front airbag
occurs.These components supplement the
seatbelts by reducing the impact to the
occupant’s head, chest and knees.
NOTEOnly driver’s SRS frontal airbag and
front passenger’s SRS frontal airbag
are controlled by the SUBARU
advanced frontal airbag system.
▼ Driver’s SRS frontal airbagThe driver’s SRS frontal airbag uses a
dual stage inflator. The inflator operates in
different ways depending on the severity
of impact.SRS airbag system warning light

▼Front passenger’s SRS frontal
airbagThe front passenger’s SRS frontal airbag
uses a dual stage inflator. The inflator
operates in different ways depending on
the severity of impact.1) Occupant detection sensorsThe occupant detection sensors are
installed between the seat and seat rails,
and monitor the physique and posture of
the front passenger. Using this informa-
tion, the occupant detection system deter-
mines whether the front passenger’s SRS
frontal airbag should be deployed or not.
The occupant detect ion 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
pretensioner. For details about the
seatbelt pretensioner, refer to "Seatbelt
Pretensioners" P44.

If you think that the Front passenger's
frontal airbag ON/OFF indicator is incor-
rect, take the following actions.
 Ensure that no article is placed on the
seat other than the occupant.
 Ensure that the backward-forward
position 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 ON indicator still remains illuminated
while the OFF indicator turns off after
taking relevant corrective actions
described above, 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 small adult always
take the rear seat.
NOTEWhen a small adult is seated in the
front passenger’s seat, the SUBARU
advanced frontal airbag system may or
may not activate th e front passenger’s
SRS frontal airbag depending on the
occupant’s seating posture. If the OFF
indicator remains illuminated while the
ON indicator turns off when a small
adult is seated in the front passenger's
seat, see next section “Conditions in
which front passenger's SRS frontal
airbag is activated.”▼ Conditions in which front

WARNING
NEVER INSTALL A CHILD
RESTRAINT SYSTEM IN THE
FRONT PASSENGER’S SEAT EVEN
IF THE FRONT PASSENGER’S SRS
FRONTAL AIRBAG IS DEACTI-
VATED. Be sure to install it in the
REAR seat in a correct manner.
Also, it is strongly recommended
that any child restraint system
(including any 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 front
passenger’s seat may be killed or
severely injured should the front
passenger’s SRS frontal airbag
deploy. REAR seats are the safest
place for children.
CAUTION
Observe the following precautions
as it increase the load on the front
passenger's seat and not work
properly. Do not install any accessory such
as a table or TV onto the
seatback.
 Do not allow the rear seat occu-
pant to place his/her hands or
legs on the front passenger's
seatback, or allow him/her to pull
the seatback.

This can be caused by the adult incor-
rectly sitting in the front passenger’s seat.
1. Turn the ignition switch to the “OFF”
position.
2. 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.
3. Turn the ignition switch to the “ON”
position.
If the OFF indicator remains illuminated
while the ON indica tor remains off, take
the following actions.
1. Turn the ignition switch to the “OFF”
position.
2. Make sure that the front passenger
does not use a blanket, extra seat
cushion, seat cover, extra seat heater or
massager, etc.
3. If wearing excessive layers of clothing,
the front passenger should remove any
unnecessary items before sitting in the
front passenger’s seat, or should sit in a
rear seat.
4. 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 turn off for 2 seconds. Now, the ON
indicator should illuminate while the OFF
indicator remains off.
If the OFF indicator still remains illumi-
nated while the ON indicator remains off,
ask the occupant to move to the rear seat
and immediately contact your SUBARU
dealer for an inspection.
CAUTION
When the front passenger's seat is
occupied by an adult, observe the
following precautions.Failure to do so may lessen the load
on the front passenger's seat, deac-
tivating the fron t passenger's SRS
frontal airbag despite the fact that
the seat is occupied by an adult.This may result in personal injury. Do not allow the rear seat occu-
pant 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. Do not squeeze any article
between the front passenger's

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 acti-
vation 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 sensors. 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
passenger’s modules) instructing the
module(s) to inflate the SRS frontal
airbag(s).
