5-2. Steps to take in an emergency
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 30 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
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 30 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
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).

5-2. Steps to take in an emergency
■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.
