By way of example, the following table
shows the required tire pressures that
correspond to various outside tempera-
tures when the temperature in the garage
is 608F (15.68C).
Example:
Tire size: 235/45R17 97W, 245/40R18
97Y
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm
2
)
Rear: 32 psi (220 kPa, 2.2 kgf/cm
2
)
Garage temperature: 608F (15.68C)
Outside
temperature
Adjusted pressure
[psi (kPa, kgf/cm
2
)]
Front Rear
308F (−18C) 36 (250, 2.5) 35 (240, 2.4)
108F (−128C) 38 (265, 2.65) 37 (255, 2.55)
−108F (−238C) 41 (280, 2.8)
39 (270, 2.7)
If the low tire pressure warning light
illuminates when you drive the vehicle in
cold outside air after adjusting the tire
pressures in a warm garage, re-adjust the
tire pressures using the method described
above. Then, increase the vehicle speed
to at least 20 mph (32 km/h) and check to
see that the low tire pressure warning light
goes off a few minutes later. If the low tire
pressure warning light does not go off, the
tire pressure monitoring system may not
be functioning normally. In this event, go to
a SUBARU dealer to have the system
inspected as soon as possible.
While the vehicle is driven, friction be-
tween tires and the road surface causes
the tires to warm up. After illumination of
the low tire pressure warning light, any
increase in the tire pressures caused by an
increase in the outside air temperature or
by an increase in the temperature in the
tires can cause the low tire pressure
warning light to go off.
It may not be possible to install TPMS
valves on certain wheels that are on the
market. Therefore, if you change the
wheels (for example, a switch to snow
tires), use wheels that have the same part
number as the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
in the instrument panel will illuminate
steadily after blinking for approximately
one minute.
WARNING
If the low tire pressure warning light
does not illuminate briefly after the
ignition switch is turned on or the
light illuminates steadily after blink-
ing for approximately one minute,
you should have your Tire Pressure
Monitoring System checked at a
SUBARU dealer as soon as possi-
ble.
If this light illuminates while driving,
never brake suddenly. Instead, per-
form the following procedure. Other-
wise an accident involving serious
vehicle damage and serious perso-
nal injury could occur.
1) Keep driving straight ahead while
gradually reducing speed.
2) Slowly pull off the road to a safe
place.
If this light still illuminates while
driving after adjusting the tire pres-
sure, a tire may have significant
damage and a fast leak that causes
the tire to lose air rapidly. If you have
a flat tire, refer to “Flat Tires” �P381.
When a wheel rim is replaced with-
out the original pressure sensor/
transmitter being transferred, the
low tire pressure warning light will
illuminate steadily after blinking for
approximately one minute. This in-
dicates the TPMS is unable to moni-
tor all four road wheels. Contact
your SUBARU dealer as soon as
possible for tire and sensor replace-
ment and/or system resetting. If the
light illuminates steadily after blink-
