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.

132 1-7. Safety information
BRZ_U (A4450BE-A)
The front passenger’s frontal airbag ON and OFF indicators show
you the status of the front passenger’s SRS frontal airbag. When
the engine switch is turned to the “ON” position, (vehicles without a
keyless access with push button start system), or the push-button
ignition switch is turned to “ON” mode (vehicles with a keyless
access with push button start system), both the ON and OFF indi-
cators illuminate for 6 seconds during the system check. After the
system check, both the ON and OFF indicators turn off for 2 sec-
onds. Then, either the ON or OFF indicator illuminates depending
on the condition of the front passenger’s frontal airbag.
When the OFF indicator remains off and ON indicator illuminates,
the front passenger’s frontal airbag may deploy during a collision.
When the OFF indicator illuminates and ON indicator remains off,
the front passenger’s frontal airbag does not deploy during a colli-
sion.
If the front passenger’s frontal airbag ON and OFF indicators
remain on when the engine switch is turned to the “ON” position
(vehicles without a keyless access with push button start system)
or the push-button ignition switch is turned to “ON” mode (vehicles
with a keyless access with push button start system), or the indica-
tors remain off after the system check, the system may be malfunc-
tioning. Have the vehicle inspected by your SUBARU dealer
immediately.
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 monitoring system.

*
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. 145)
*
9: In case the indicator is not illuminated, consult this manual on how to installing the child restraint system properly. ( →P. 145)
