■Notes for locking the doors
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
●When the lock operation is performed using the lock sensor, recognition
signals will be shown up to two consecutive times. After this, no recogni-
tion signals will be given.
●If the door handle becomes wet when washing the vehicle while the
access key is within the effective range, the door may lock and unlock
repeatedly. In this case, place the access key in a location 6 ft. (2 m) or
more away from the vehicle (take care to ensure that the key is not sto-
len), and continue to wash the vehicle.
●If the access key is inside the vehicle and a door handle becomes wet
during a car wash, a buzzer will sound outside the vehicle. To turn off the
alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice,
snow, mud, etc. Clean the lock sensor and attempt to operate it again.
■Notes for the unlocking function
●A sudden approach to the effective range or door handle may prevent the
doors from being unlocked. In this case, return the door handle to the
original position and check that the doors unlock before pulling the door
handle again.
●Gripping the door handle when wearing a glove may not unlock the door.
Remove the gloves and touch the sensor on the back of the handle
again.
●If the door handle becomes wet when washing the vehicle while the
access key is within the effective range, the door may lock and unlock
repeatedly. In this case, place the access key in a location 6 ft. (2 m) or
more away from the vehicle (take care to ensure that the key is not sto-
len), and continue to wash the vehicle.
●If there is another access key in the detection area, it may take slightly
longer to unlock the doors after the door handle is gripped.

1-7. Safety information
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and front pas-
senger. The front passenger's airbag system consists of the front
passenger occupant detection control module etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag control module. The
airbag control module consists of an airbag sensor.
In certain types of severe front or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help restrain the motion
of the occupants.

■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, parts of the front and rear pillars, and roof side
rails, may be hot for several minutes. The airbag itself may also be hot.
●The windshield may crack.

1-7. Safety information
■Driver’s SRS frontal airbag
The driver’s SRS frontal airbag uses a dual stage inflator. The inflator oper-
ates in different ways depending on the severity of impact.
Have the system inspected by your SUBARU dealer immediately if the SRS
airbag system warning light illuminates.
NOTE
The driver’s SRS side airbag and SRS curtain airbag are not controlled by
the SUBARU advanced frontal airbag system.
■Front passenger’s SRS frontal airbag
The front passenger’s SRS frontal ai rbag uses a dual stage inflator. The
inflator operates in different ways depending on the severity of impact.
The occupant detection system sensor is installed under the seat upholstery
and monitors 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 nor-
mal. In this case, although the front passenger’s SRS frontal airbag does not
operate, the front passenger’s seatbelt pretensioner operates with the
driver’s seatbelt pretensioner. For details about the seatbelt pretensioner,
refer to “Seatbelt pretensioners”. ( →P. 59)
Observe the following precautions. 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.
●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 than a
genuine SUBARU accessory under the front passenger’s seat.
●Do not place anything (shoes, umbrella, etc.) under the front passenger’s
seat.
●Do not place a magnet near the seatbelt buckle.

Before driving
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 dealer immediately if the SRS
airbag system warning light illuminates.
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. Do not use the front passenger’s seat while driving
the vehicle to your SUBARU dealer.
NOTE
The front passenger’s SRS side airbag and SRS curtain airbag are not con-
trolled by the SUBARU advanced frontal airbag system.
■Passenger’s frontal airbag ON and OFF indicators
→P. 123
■Occupant detection system
The occupant detection system sensor is installed under the seat upholstery
and monitors 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.
If the front passenger’s seat cushion is wet, this may adversely affect the
ability of the system to determine deploy ment. If the seat cushion is wet, the
front passenger should stop sitting on the front passenger’s seat. Wipe off
liquid from the seat immediately, let the seat dry naturally and then check the
SRS airbag system warning light as follows.
●If the SRS airbag system warning light illuminates, keep the seat dry until
the warning light turns off. If the SRS airbag system warning light stays
on even when the seat has dried, do not allow anyone to sit on the front
passenger’s seat and have the system checked by your SUBARU dealer.
●If the SRS airbag system warning light does not illuminate, check that the
front passenger’s frontal airbag ON and OFF indicators work properly. If
the indicators do not work properly, do not allow anyone to sit on the front
passenger’s seat and have the system checked by your SUBARU dealer.

1-7. Safety information
The SRS airbag can function only when the ignition switch is in the “ON”
position.
The SUBARU advanced frontal airbag system is designed to determine the
activation or deactivation condition of the front passenger’s SRS frontal air-
bag depending on the characteristic of the item(s) or person on the front
passenger’s seat monitored by the front passenger’s occupant detection
system 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 sys-tem.
If the front sub sensors and the impact sensors in the airbag control module
detect a predetermined 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).
The driver’s and front passenger’s SRS frontal airbags use dual stage infla-
tors. The two inflators of each airbag are triggered either sequentially or
simultaneously, depending on the severity of impact, in the case of the
driver’s SRS frontal airbag and depending on the severity of impact and the
characteristic of the item(s) or person 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 passen-
ger’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 con-
trol 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.
