your vehicle.

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.
CAUTION
Contact your SUBARU dealer if the
following occurs, even if it is not yet
time to change the filter.

the vents.

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