SUBARU dealer immediately if the SRS

Front passenger’s SRS frontal
airbag
The 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 system sensors
are installed between the seat and seat
rails, and monitor 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 no t 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.

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
seatback and seat cushion.Do not spill liquid on the front
passenger’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

sory under the front passenger’s
seat.Do not place anything (shoes,
umbrella, etc.) under the front
passenger’s seat.Do not place any objects (books,
etc.) around the front
passenger’s seat.

posture of the front passenger. Using this
information, the occupant detection
system determines whether the frontpassenger’s SRS frontal airbag should be
deployed or not.

WARNING
Do not kick the front passenger seat
or subject it to severe impact. Oth-
erwise, the SRS airbag system
warning light may illuminate to indi-
cate a malfunction of the front pas-
senger occupant detection system.
In this case, contact your SUBARU
dealer immediately.
CAUTION
Electrical devices, such as cell
phones, laptops, portable music
players, or electronic games, espe-
cially when connected to the acces-
sory power outlet and placed on the
front passenger’s seat or used by
the person sitting in the front pas-
senger’s seat, may affect the opera-
tion of the occupant detection
system. If either of the following sit-
uations occurs when using an elec-
tronic device in the vehicle, at first
try to relocate that device to avoid it
creating any interference. The SRS airbag system warning
light illuminates.The front passenger’s frontal
airbag ON and OFF indicators
operate erratically.
If the device continues to cause
interference, the use of that device
in the vehicle should be discontin-
ued.

▽Examples of the types of acci -
dents in which the SRS side
airbag and SRS curtain airbag
are not designed to deploy in
most cases1) The vehicle is involved in frontal colli- sion with another vehicle (moving or stationary).
2) The vehicle is struck from behind.
3) The vehicle pitches end over end.
In the event of accidents like those illus-
trated, the SRS side airbag and SRS
curtain airbag are not designed to deploy
in most cases.1) First impact
2) Second impact
A) SRS curtain airbag
B) SRS side airbagIn an accident where the vehicle is struck
from the side more than once, the SRS
side airbag and SRS curtain airbag deploy
only once on the first impact.
Example: In the case of a double side
impact collision, first with one vehicle and
immediately followed by another from the same direction, once the SRS side airbag
and SRS curtain airbag are activated on
the first impact, they will not be activated
on the second.

SRS airbag system warn
ing light will show
normal system operation by illuminating
for approximately 6 seconds when the
ignition switch is turned to the “ON” posi-
tion.
