temperature 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 8F (15.6 8C).
Example:
Tire size: P205/55R16 89V and
P205/50R17 88V
Standard tire pressures:
Front: 33 psi (230 kPa, 2.3 kgf/cm

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
turns off a few minutes later. If the low tire
pressure warning light does not turn 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 turn off.
System resetting is necessary when the
wheels are changed (for example, a
switch to snow tires) and new TPMS
valves are installed on the newly fitted
wheels. Have this work performed by a
SUBARU dealer following wheel replace-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 the standard-equipment
wheels. Without four operational TPMS
valve/sensors on the wheels, the TPMS
will not fully function and the warning light
on the combination meter will illuminate
steadily after blinking for approximatelyone minute.
When a tire is replaced, adjustments are
necessary to ensure continued normal
operation of the tire pressure monitoring
system. As with wheel replacement, there-
fore, you should have the work performed
by a SUBARU dealer.
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 and keep
driving straight ahead while gradu-
ally reducing speed. Then slowly
pull off the road to a safe place.
Otherwise an accident involving
serious vehicle damage and serious
personal injury could occur.
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

11-34Maintenance and service
NOTE .The air pressure in a tire increases
by approximately 4.3 psi (30 kPa, 0.3 kgf/cm
2) when the tire becomes warm.
. The tires are considered cold when
the vehicle has been parked for at least
three hours or has been driven less
than one mile (1.6 km).
WARNING
Do not let air out of warm tires to
adjust pressure. Doing so will result
in low tire pressure.
Incorrect tire pressures detract from con-
trollability and ride comfort, and they
cause the tires to wear abnormally. .
Correct tire pressure (tread worn
evenly)
Roadholding is good, and steering is
responsive. Rolling resistance is low, so
fuel consumption is also lower. .
Abnormally low tire pressure (tread
worn at shoulders)Rolling resistance is high, so fuel con-
sumption is also higher.

corresponding fuse. If a fuse has blown,
replace it.
1. Turn the ignition switch to the “LOCK ”
position and turn off all electrical acces- sories.
2. Remove the cover.
3. Determine which fuse may be blown.
Look at the back side of each fuse box
cover and refer to “Fuses and circuits ”
F 12-12.
4. Pull out the fuse with the fuse puller.
5. Inspect the fuse. If it has blown,
replace it with a spare fuse of the samerating.
6. If the same fuse blows again, this
indicates that its system has a problem.
Contact your SUBARU dealer for repairs. Main fuse
Main fuse box
The main fuses are designed to melt
during an overload to prevent damage to
the wiring harness and electrical equip-
ment. Check the main fuses if any
electrical component fails to operate (ex-
cept the starter motor) and other fuses are
good. A melted main fuse must be
replaced. Use only replacements with the
same specified rating as the melted main
fuse. If a main fuse blows after it is
replaced, have the electrical system
checked by your nearest SUBARU dealer. Installation of accessories
Always consult your SUBARU dealer
before installing fog lights or any other
electrical equipment in your vehicle. Such
accessories may cause the electronic
system to malfunction if they are incor-
rectly installed or if they are not suited for
the vehicle.

grade C corresponds to a level of
performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety Stan-
dards No. 109. Grades B and A
represent higher levels of perfor-
mance on the laboratory test wheel
than the minimum required by law.
WARNING
The temperature grade for this
tire is established for a tire
that is properly inflated and
not overloaded. Excessive
speed, underinflation, or ex-
cessive loading, either sepa-
rately or in combination, can
cause heat buildup and possi-
ble tire failure. Reporting safety defects (U.S.A.)
If you believe that your vehicle has
a defect which could cause a
crash or could cause injury or
death, you should immediately in-
form the National Highway Traffic
Safety Administration (NHTSA) in
addition to notifying Subaru of
America, Inc.
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of vehi-
cles, it may order a recall and
remedy campaign. However,
NHTSA cannot become involved
in individual problems between
you, your dealer, or Subaru of
