WARNING
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and
can cause death or serious injury especially if the front passenger is very
close to the airbag. The front passenger seat should be as far from the air-
bag as possible with the seatback adjusted, so the front passenger sits
upright.
● Improperly seated and/or restrained infants and children can be killed or
seriously injured by a deploying airbag. An infant or child who is too small
to use a seatbelt should be properly secured using a child restraint sys-
tem. SUBARU strongly recommends that all infants and children be placed
in the rear seats of the vehicle and properly restrained. The rear seats are
safer for infants and children than the front passenger seat. ( →P. 141)
●Do not sit on the edge of the seat or
lean against the dashboard.
● Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
● Do not allow the front seat occupants to
hold items on their knees.
● Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.

Front passenger occupant detection system
Your vehicle is equipped with a front passenger occupant detection
system. Using the sensors installed under the seat cover, the system
detects the conditions of the front passenger seat and activates or
deactivates the frontal airbag for front passenger seat. 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 not
a malfunction. If the seatbelt buckle switch and/or front passenger’s
occupant detection system have fa iled, the SRS airbag system warn-
ing light will illuminate. Have the system inspected by your SUBARU
dealer immediately if the SRS ai rbag system warning light illumi-
nates.
If your vehicle has sustained impact , this may affect the proper func-
tion of the SUBARU advanced front al airbag system. Immediately
contact your SUBARU dealer a nd have your vehicle inspected. Do
not use the front passenger seat while driving to your SUBARU
dealer.

*
1: The occupant detection system does not operate during self-
checking.
*
2: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may not
recognize him/her as an adult depending on his/her physique and
posture.
*
3: In the event the front passenger does not wear a seatbelt.
*
4: The front passenger’s SRS side airbag, SRS curtain airbag and seatbelt pretensioner are not controlled by the occupant detection
system.
*
5: For some children, child in seat, child in booster seat or child in convertible seat, the system may not recognize him/her as a
child. Factors which may affect this can be the physique or pos-
ture.
Children who have outgrown a child restraint system should
always wear the seatbelt when sitting in the seat irrespective of
whether the airbag is deactivated or activated.
*
6: When a child restraint system is installed on the front passenger seat, do not place any article on the seat other than the child
occupant and a child restraint system.
Failure to do so may prevent the front passenger occupant detec-
tion system from functioning correctly or cause the system to fail.
*
7: Do not place more than one child on the front passenger seat. Failure to do so may prevent the front passenger occupant detec-
tion system from functioning correctly.
*
8: Never install a child restraint system on the front passenger seat. See the caution that follows regarding installation of a child
restraint system. ( →P. 146)
*
9: In case the indicator is not illuminated, consult this manual on how to installing the child restraint system properly. ( →P. 146)

WARNING
■
Front passenger occupant detection system precautions
Observe the following precautions regarding front passenger occupant
detection system.
Failure to do so may cause the occupant detection system to not function
correctly, resulting in death or serious injury.
● Wear the seatbelt properly.
● Do not apply excessive force to the seat.
● Do not put sharp object(s) on the seat or pierce the seat upholstery.
● Do not put objects under the front passenger seat.
● Do not use a seat accessory, such as a cushion or seat cover, that covers
the seat cushion surface.
● Do not spill liquid on the front passenger seat. If liquid is spilled, wipe it off
immediately and dry the seat. If the airbag warning light illuminates, dry
the seat until the warning light turns off. If the airbag warning light stays on
even when the seat has dried, do not allow anyone to sit on the front pas-
senger seat and have the system checked by your SUBARU dealer. If the
airbag warning light does not illuminate, check that the airbag ON/OFF
indicator light works properly. If the indicator light does not work properly,
do not allow anyone to sit in the front passenger’s seat and have the sys-
tem inspected by your SUBARU dealer.
● Do not remove or disassemble the front passenger seat. Also, do not
replace or modify the seat upholstery or foam inside the seat.
● Do not install any accessory (such as an audio amplifier) other than a gen-
uine SUBARU accessory under the front passenger’s seat.
● Do not place a magnetized items near the seatbelt buckle.

WARNING
■Front passenger occupant detection system precautions
●Never install a rearward facing child seat in the front passenger’s seat
even if the front passenger’s SRS frontal airbag is deactivated. Be sure to
install it in the rear seat in a correct manner. Also, it is strongly recom-
mended that any forward facing 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 front passenger’s seat may be killed or severely injured should the
front passenger’s SRS frontal airbag deploy. SUBARU believes that the
rear seats are the safest place for children
● If luggage or electronic devices are placed on the front passenger seat,
the OFF indicator may turn off and the ON indicator may illuminate. If this
occurs, the front passenger’s airbag may deploy during a collision. If this is
not desirable, remove the luggage or el ectronic devices from the front pas-
senger seat.
● Modifications for persons wi th disabilities that may affect the front passen-
ger occupant detection system. (U.S. onl y) Removing, replacing or modify-
ing any parts of the front seats, seatbelts, front bumper, front side frame,
instrument panel, combination meter, steering wheel, steering column,
tires, suspension or floor panel can affect the operation of the SUBARU
front passenger occupant detection system.
