Tire pressure monitoring system (TPMS) (U.S.-spec. models)
344
The tire pressure monitoring sys-
tem does not function when the
vehicle is stationary. After adjust-
ing the tire pressures, increase
the vehicle speed to at least 20
mph (32 km/h) to start the TPMS
rechecking of the tire inflation
pressures. If the tire pressures
are now above the severe low
pressure threshold, the low tire
pressure warning light should
turn off a few minutes later.

WARNING
.
If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
Otherwise, an accident involving
serious vehicle damage and ser-
ious personal injury could occur.
(1) Keep driving straight ahead
while gradually reducing
speed.
If this light still illuminates while
driving after adjusting the tire
pressure, a tire may have signifi-
cant damage and a fast leak that
causes the tire to lose air rapidly.
If you have a flat tire, replace it
with a spare tire as soon as
possible.
(2) Slowly pull off the road to a
safe location.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the tire inflation
pressure label. The tire infla-
tion pressure label is located
on the door pillar on the
driver’s side.
Low tire pressure warning light
The tire pressure monitoring system pro-
vides the driver with a warning message
when tire pressure is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven at
speeds above 20 mph (32 km/h). Also, this
system may not react immediately to a
sudden drop in tire pressure (for example,
a blow-out caused by running over a sharp
object).
.
When a spare tire is mounted or a
wheel rim is replaced without the
original pressure sensor/trans-
mitter being transferred, the low
tire pressure warning light will
illuminate steadily after blinking
for approximately 1 minute. This
indicates the TPMS is unable to
monitor all four road wheels.
Contact your SUBARU dealer as
soon as possible for tire and
sensor replacement and/or sys-
Even when the vehicle is driven a
very short distance, the tires get
warm and their pressures in-
crease accordingly. Be sure to
let the tires cool thoroughly be-
fore adjusting their pressures to
the standard values shown on the
tire inflation pressure label. Refer
to “Tires and wheels” �P471.
