■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, 3.87 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.

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.

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.

If you have a flat tire
Your vehicle is equipped with a spare tire. The flat tire can be
replaced with the spare tire.
■Before jacking up the vehicle
●Stop the vehicle in a safe place on a hard, flat surface.
● Set the parking brake.
● Shift the select lever to P (vehicles with an automatic trans-
mission) or shift lever to R (vehicles with a manual transmis-
sion).
● Stop the engine.
● Turn on the hazard warning flashers. ( →P. 418)

■The compact spare tire (vehicles with a compact spare tire)
●The compact spare tire is identified by the label “TEMPORARY USE
ONLY” on the tire sidewall.
Use the compact spare tire temporarily only in an emergency.
●Make sure to check the tire pressure of the compact spare tire.
(→ P. 502)
■When using the compact spare tire (vehicles with a tire pressure
monitoring system)
As the compact spare tire is not equipped with the tire pressure warning
valve and transmitter, low inflation pressure of the spare tire will not be
warned. Also, if you replace the compact spare tire after the tire pressure
warning light comes on, the light remains on.
■If you have a flat rear tire (vehicles with a compact spare tire)
Install the compact spare tire on the front of the vehicle. Perform the fol-
lowing steps.
Replace a front tire with the compact spare tire.
Replace the flat rear tire with the tire removed from the front of
the vehicle.
■After completing the tire change (vehicles with a tire pressure mon-
itoring system)
The tire pressure monitoring system must be reset. ( →P. 375)
