: 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.

: Front passenger’s seatbelt buzzer:

The front passenger’s seatbelt buzzer sounds to alert the front passenger
that his or her seatbelt is not fastened. The buzzer sounds once if the vehi-
cle reaches a speed of 12 mph (20 km/h). 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.

■

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/cm

2

 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.

WARNING

■

If the tire pressure warning light comes on (if equipped)
Be sure to observe the following precautions. Failure to do so could
cause loss of vehicle control and result in death or serious injury.

●

Stop your vehicle in a safe place as soon as possible. Adjust the tire
inflation pressure immediately.

●

If the tire pressure warning light comes on even after tire inflation pres-
sure adjustment, it is probable that you have a flat tire. Check the tires.
If the tire is flat, change to the spare tire and have the flat tire repaired
by the nearest SUBARU dealer.

●

Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate,
you could lose control of the steering wheel or the brakes.

■

If a blowout or sudden air leakage should occur (vehicles with a tire
pressure monitoring system)
The tire pressure monitoring system may not activate immediately.

5-2. Steps to take in an emergency

BRZ_U

WARNING

■

Maintenance of the tires (vehicles with a tire pressure monitoring
system)
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pressure
label (tire and load information label). (If your vehicle has tires of a differ-
ent size than the size indicated on the vehicle placard or tire inflation
pressure label [tire and load information label], you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that illuminates a low tire pressure
telltale (tire pressure warning light) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale
(tire pressure warning light) illuminates, you should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driv-
ing on a significantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte-
nance, and it is the driver's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached the level to trigger
illumination of the TPMS low tire pressure telltale (tire pressure warning
light).
Your vehicle has also been equipped with a TPMS malfunction indicator
to indicate when the system is not operating properly. The TPMS mal-
function indicator is combined with the low tire pressure telltale (tire pres-
sure warning light). When the system detects a malfunction, the telltale
will flash for approximately one minute and then remain continuously illu-
minated. This sequence will continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the malfunction indicator is illu-
minated, the system may not be able to detect or signal low tire pressure
as intended.

WARNING

TPMS malfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alternate tires and wheels
allow the TPMS to continue to function properly.

CAUTION

■

To ensure the tire pressure monitoring system operates properly
(vehicles with a tire pressure monitoring system)
Do not install tires with different specifications or makers, as the tire
pressure monitoring system may not operate properly.
