proach the curbs as squarely as possible. Also,
make sure the tires are not pressed against thecurb when you park the vehicle.If you feel unusual vibration while driving or
find it difficult to steer the vehicle in a straight
line, one of the tires and/or wheels may be dam- aged. Drive slowly to the nearest authorized
SUBARU dealer and have the vehicle inspected. Tire pressures and wear
Maintaining the correct tire pressures helps to maxi-
mize the tires ’ service lives and is essential for good
running performance. Check and, if necessary, ad-
just the pressure of each tire (including the spare) at least once a month (for example, during a fuel stop)
and before any long journey.
Check the tire pressures when the tires are cold.
Use a pressure gauge to adjust the tire pressures to
the values shown on the tire placard. The tire plac-
ard is located on the door pillar on the driver ’s side.
Driving even a short distance warms up the tires
and increases the tire pressures. Also, the tire pres-
sures are affected by the ambient temperature. It is
best to check tire pressure outdoors before driving the vehicle.
When a tire becomes warm, the air inside it ex-
pands, causing the tire pressure to increase. Be
careful not to mistakenly release air from a warm tire
to reduce its pressure.
