WARNING
■
When refueling
Observe the following precautions to prevent fuel overflowing from the fuel
tank:
● Securely insert the fuel nozzle into the fuel filler neck
● Stop filling the tank after the fuel nozzle automatically clicks off
● Do not top off the fuel tank
● Observe other precautions that are posted at the service station.
● Turn the cap to the right until it clicks to ensure that it is fully tightened. If
the cap is not securely tightened, fuel spillage could occur in the event of
an accident, creating a fire hazard.
■ When replacing the fuel cap
Do not use anything but a genuine fuel tank cap designed for your vehicle.
Doing so may cause a fire or other incident which may result in death or seri-
ous injury.
CAUTION
■Refueling
● Do not spill fuel during refueling.
Doing so may damage the vehicle, such as causing the emission control
system to operate abnormally or damaging fuel system components or the
vehicle's painted surface.
● Never add any cleaning agents to the fuel tank. The addition of a cleaning
agent may cause damage to the fuel system.
● Immediately put fuel in the tank whenever the low fuel warning light illumi-
nates. Engine misfires as a result of an empty tank could cause damage to
the engine. Continuing to operate your vehicle at an extremely low fuel
level may result in a reduction of engine performance.

BRZ_U (A4450BE-A)
WARNING
■SRS airbag
●Put children aged 12 and under in the
rear seat properly restrained at all
times. The SRS airbag deploys with
considerable speed and force and can
injure or even kill children, especially if
they are 12 years of age and under and
are not restrained or improperly
restrained. Because children are lighter
and weaker than adults, their risk of
being injured from deployment is
greater.
For that reason, we strongly recom-
mend that ALL children (including those
in child seats and those that have out-
grown child restraint devices) sit in the
REAR seat properly restrained at all
times in a child restraint device or in a
seatbelt, whichever is appropriate for
the child's age, height and weight.
Secure ALL types of child restraint
devices (including forward facing child
seats) in the REAR seats at all times.
According to accident statistics, chil-
dren are safer when properly restrained
in the rear seating positions than in the
front seating positions.
For instructions and precautions con-
cerning the child restraint system, refer
to “Child restraint systems”. ( →P. 141)

Before driving
BRZ_U (A4450BE-A)
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)
● Slight abrasions, burns, bruising etc., may be sustained from SRS air-
bags, due to the extremely high speed deployment (inflation) by hot
gases.
● 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.

■
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 airbag 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. 61)
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.

102 1-7. Safety information
BRZ_U (A4450BE-A)
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. 131
■ 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 deployment. 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.
