*1: Driver’s seatbelt buzzer:Vehicles without a keyless access with push button start system
The driver’s seatbelt buzzer sounds to alert the driver that his or her seatbelt
is not fastened. Once the engine switch is turned to the “ON” position, the
buzzer sounds for 6 seconds. If the vehicle reaches a speed of 12 mph (20
km/h), the buzzer sounds once. If the seatbelt is still unfastened after 24
seconds, the buzzer will sound intermittently for 10 seconds. Then, if the
seatbelt is still unfastened, the buzzer will sound in a different tone for 20
more seconds.
Vehicles with a keyless access with push button start system
The driver’s seatbelt buzzer sounds to alert the driver that his or her seatbelt
is not fastened. Once the
push-button ignition switch is turned to “ON”
mode
, the buzzer sounds for 6 seconds. If the vehicle reaches a speed of
12 mph (20 km/h), the buzzer sounds once. If the seatbelt is still unfastened
after 24 seconds, the buzzer will sound intermittently for 10 seconds. Then,
if the seatbelt is still unfastened, the buzzer will sound in a different tone for
20 more seconds.
*2: Front passenger’s seatbelt buzzer:
The front passenger’s seatbelt buzzer sounds to alert the front passenger

5-2. Steps to take in an emergency
BRZ_U
■
Low fuel level warning light
When the vehicle is on an incline, curve and so forth, the fuel inside the tank
moves, which may cause the warning light to come on early.
■ Front passenger detection sensor and passenger seatbelt reminder
and warning buzzer
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash and warning
buzzer to sound, even if a passenger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■
When the tire pressure warning light comes on (if equipped)
Check the tire inflation pressure and adjust to the appropriate level.
■The tire pressure warning light may turn on due to natural causes
(if equipped)
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the tire inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire (vehicles with a tire pres-
sure monitoring system)
The compact spare tire is not equipped with a tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire has been replaced with the spare
tire. Replace the spare tire with the repaired tire and adjust the tire infla-
tion pressure. The tire pressure warning light will go off after a few min-
utes.

■If the tire pressure monitoring system is inoperative (if equipped)
The tire pressure monitoring system will be disabled in the following con-
ditions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with tire pressure warning valves and transmit-
ters are used.
●If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
●If the tire inflation pressure is 55 psi (380 kPa, 3.80 kgf/cm2 or bar) or
higher.
The tire pressure monitoring system may be disabled in the following
conditions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine SUBARU wheels are used. (Even if you use SUBARU
wheels, the tire pressure monitoring system may not work properly
with some types of tires.)
●If tire chains are used.
●If a large metallic object which can interfere with signal reception is
put in the trunk.
■If the tire pressure warning light frequently comes on after blinking
for approximately one minute (if equipped)
If the tire pressure warning light frequently comes on after blinking for
approximately one minute when the push-button ignition switch is turned
to “ON” mode (vehicles with a keyless access with push button start sys-
tem) or the engine switch is turned to the “ON” position (vehicles without
a keyless access with push button start system), have it checked your
SUBARU dealer.
