Tire Pressure Monitoring System (Tpms) (U.s.-Spec. Models) - Subaru WRX 2021 Owner's Manual

9-8
In case of emergency/Flat tires
. When you store a flat tire, be sure
to set the rear seatback to the
upright position. If you fold down
the seatback, an accident or
injury may occur when the flat
tire suddenly moves.
& Tire pressure monitoring
system (TPMS) (U.S.-spec.
models)
Low tire pressure warning light
The tire pressure monitoring system pro-
vides the driver with the warning message
indicated by sending a signal from a
sensor that is installed in each wheel when
tire pressure is severely low.
The tire pressure monitoring system will
activate only when the vehicle is driven.
Also, this system may not react immedi-
ately to a sudden drop in tire pressure (for
example, a blow-out caused by running
over a sharp object).
WARNING
. If the low tire pressure warning
light illuminates while driving,
never brake suddenly. Instead,
perform the following procedure.
(1) Keep driving straight ahead
while gradually reducing
speed.
(2) Slowly pull off the road to a
safe place. Otherwise an acci-
dent involving serious vehicle
damage and serious personal
injury could occur.
(3) Check the pressure for all four
tires and adjust the pressure
to the COLD tire pressure
shown on the tire inflation
pressure label on the door
pillar on the driver's side.
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, refer to "Flat
tires" F9-4.
. 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 one 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-
tem resetting.
. When a tire is repaired with liquid
sealant, the tire pressure warning
valve and transmitter may not
operate properly. If a liquid sea-
lant is used, contact your nearest
SUBARU dealer or other qualified
service shop as soon as possi-
ble. Make sure to replace the tire
pressure warning valve and
transmitter when replacing the
tire. You may reuse the wheel if
there is no damage to it and if the
sealant residue is properly
cleaned off.
