ery difference of 10°F (5.6°C) between the
temperature in the garage and the tem-
perature outside. By way of example, the
following table shows the required tire
pressures that correspond to various out-
side temperatures when the temperature
in the garage is 60°F (15.6°C).
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm
Rear: 32 psi (220 kPa, 2.2 kgf/cm
Garage temperature: 60°F (15.6°C)
Outside Adjusted pressure
temperature [psi (kPa, kgf/cm

30°F (–1°C) 36 (250, 2.5)
10°F (–12°C) 38
(265, 2.65)
–10°F 40 (280, 2.8)
(–23°C)
If the low tire pressure warning light
comes on 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
2
) the tires to warm up. After illumination of
2
) the low tire pressure warning light, any in-
crease in the tire pressures caused by an
increase in the outside air temperature or
by an increase in the temperature in the
2
)] tires can cause the low tire pressure warn-
ing light to go off.

System resetting is necessary when the
35 (240, 2.4)
wheels are changed (for example, a
switch to snow tires) and new TPMS
37
valves are installed on the newly fitted
(255, 2.55)
wheels. Have this work performed by a
SUBARU dealer following wheel replace-
39 (270, 2.7)
ment.
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
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
the standard-equipment
will not fully function and the warning light
in the instrument panel will flash.
When a tire is replaced, adjustments are
necessary to ensure continued normal op-
eration of the tire pressure monitoring sys-
tem. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.
If the low tire pressure warning light
does not come on briefly after the ig-
nition switch is turned ON or the
light is flashing, you should have
your Tire Pressure Monitoring Sys-
tem checked at a SUBARU dealer as
soon as possible.
If this light comes on while driving,
never brake suddenly and keep driv-
ing straight ahead while gradually
reducing speed. Then slowly pull off
the road to a safe place. Otherwise
an accident involving serious vehi-
cle damage and serious personal in-
jury could occur.
