122 1-7. Safety information
BRZ_U (A4450BE-A)
In 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 curtain airbag

WARNING
■
If the SRS airbags deploy
Do not touch the SRS side airbag system components around the front seat
seatback with bare hands right after deployment. Doing so can cause burns
because the components can be very hot as a result of deployment.
After deployment, do not touch any part of the SRS curtain airbag system
(from the front pillar to the part of the roof side over the rear seat). Doing so
can cause burns because the components can be very hot as a result of
deployment.
■ SRS side airbag and SRS curtain airbag precautions
The SRS side airbag and SRS curtain airbag are designed only to be a sup-
plement to the primary protection prov ided by the seatbelt. They do not do
away with the need to fasten seatbelts. It is also important to wear your seat-
belt to help avoid injuries that can result when an occupant is not seated in a
proper upright position.
■ When to contact your SUBARU dealer
In the following cases, the vehicle will require inspection and/or repair. Con-
tact your SUBARU dealer as soon as possible.
● Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an acci-
dent that was not severe enough to
cause the SRS airbags to inflate.

124 1-7. Safety information
BRZ_U (A4450BE-A)
●A portion of a door is damaged or
deformed, or the vehicle was involved
in an accident that was not severe
enough to cause the SRS side airbags
and curtain airbags to inflate.
● The pad section of the steering wheel
or dashboard is scratched, cracked, or
otherwise damaged.
● The surface of the seats with the side
airbag is scratched, cracked, or other-
wise damaged.
● The portion of the front pillars, rear pil-
lars or roof side rail garnishes (padding)
containing the curtain airbags inside is
scratched, cracked or otherwise dam-
aged.

WARNING
■
SRS airbag precautions
Observe the following precauti ons regarding the SRS airbags.
Failure to do so may cause death or serious injury.
● The driver and all passengers in the vehicle must wear their seatbelts
properly.
The SRS airbags are supplemental devices to be used with the seatbelts.
● The driver should always sit upright and well back in the seat as far from
the steering wheel as practical while still maintaining full vehicle control
and the front passenger should move the seat as far back as possible and
sit upright and well back in the seat.

126 1-7. Safety information
BRZ_U (A4450BE-A)
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.

WARNING
■
SRS airbag precautions
● Do not use seat accessories which cover the parts where the SRS side
airbags inflate as they may interfere with inflation of the airbags. Such
accessories may prevent the side airbags from activating correctly, disable
the system or cause the side airbags to inflate accidentally, resulting in
death or serious injury.
● Do not strike or apply significant levels of force to the area of the SRS air-
bag components ( →P. 98).
Doing so can cause the SRS airbags to malfunction.
● Do not allow anyone to kneel on the
passenger seat toward the door or put
their head or hands outside the vehicle.
● Do not attach anything to or lean any-
thing against areas such as the dash-
board or steering wheel pad.
These items can become projectiles
when SRS driver and front passenger
airbags deploy.
● Do not attach anything to areas such as
a door, windshield glass, side door
glass, rear quarter glass, front and rear
pillar or roof side rail.

WARNING
■SRS airbag precautions
●Do not touch any of the component parts immediately after the SRS air-
bags have deployed (inflated) as they may be hot.
● If breathing becomes difficult after the SRS airbag has deployed, open a
door or window to allow fresh air in, or leave the vehicle if it is safe to do
so. Wash off any residue as soon as possible to prevent skin irritation.
● If the areas where the SRS airbags are stored, such as the steering wheel
pad and front and rear pillar garni shes, are damaged or cracked, have
them replaced by your SUBARU dealer.
■ Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications
without consulting your SUBARU dealer.
The SRS airbags may malfunction or deploy (inflate) accidentally, causing
death or serious injury.
● Installation, removal, disassembly and repair of the SRS airbags.
● Repairs, modifications, removal or replacement of the steering wheel,
instrument panel, dashboard, seats or seat upholstery, front, side and rear
pillars or roof side rails.
● Repairs or modifications of the front fender, front bumper, or side of the
occupant compartment.
● Installation of a grille guard (bull bars, kangaroo bar, etc.), snow plows,
winches.
● Modifications to the vehicle's suspension system.
● Installation of electronic devices su ch as mobile two-way radios and CD
players.
● Modifications to your vehicle for a person with a physical disability.

properly repaired, the seatbelt pret ensioners, SRS airbag system and/or
front passenger occupant detection system will not operate properly in the
event of a collision, which may increase the risk of injury.
● Flashing or flickering of the warning light
● No illumination of the warning light when the ignition switch is first turned

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.
