Air filtration system
Your vehicle’s air conditioning system is
equipped with an air filtration system.
Replace the air filter element according
to the replacement schedule shown in the
following table. This schedule should be
followed to maintain the filter ’s dust
collection ability. Under extremely dusty
conditions, the filter should be replaced
more frequently. Have your filter checked
or replaced by your SUBARU dealer. For
replacement, use only a genuine
SUBARU air filter kit.
Replacement schedule: Every 12 months or 9,300 miles (15,000
km) whichever comes first
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter: . Reduction of the air flow through
the vents.
. Windshield gets easily fogged or
misted. NOTE

tioning, heating and defroster perfor-
mance if not properly maintained.

may damage the paint surface.
6. Pour the coolant and fill to the reser-
voir tank’s “FULL ”level mark.
7. Put the radiator cap back on and
tighten firmly. At this time, make sure that the rubber gasket in the radiator cap is
correctly in place.
8. Start and race the engine at 2,000 to
3,000 rpm for 5 to 6 times within 40seconds.
9. Stop the engine and wait until the
coolant cools down (122 to 140
8F [50 to
60 8C]). If there is any loss of coolant, add
coolant to the radiator ’s filler neck and to
the reserve tank ’s “FULL ”level.
10. Put the radiator cap and reservoir cap
back on and tighten firmly. Air cleaner element
WARNING
Do not operate the engine with the
air cleaner element removed. The air
cleaner element not only filters
intake air but also stops flames if
the engine backfires. If the air
cleaner element is not installed
when the engine backfires, you
could be burned.
CAUTION
When replacing the air cleaner ele-
ment, use a genuine SUBARU air
cleaner element. If it is not used,
there is the possibility of causing a
negative effect to the engine.
The air cleaner element functions as a
filter screen. When the element is perfo-
rated or removed, engine wear will be
excessive and engine life shortened.
The air cleaner element is a dry type. It is
unnecessary to clean or wash the ele-ment. Maintenance and service
