adding it. If coolant touches the exhaust pipe, it may cause a bad smell, smoke, and/or a fire. Do not splash the engine coolant over
painted parts. The alcohol contained in the en-gine coolant may damage the paint surface.

diator cap is correctly in place.
8. Start and run the engine for more than five min-utes at 2,000 to 3,000 rpm.
9. Stop the engine and wait until the coolant coolsdown (122 to 140°F [50 to 60 °C]). 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
The air cleaner element functions as a filter screen.
When the element is perforated or removed, engine
wear will be excessive and engine life shortened.
The air cleaner element is a viscous type. It is un-
necessary to clean or wash the element.
WARNING
Do not operate the engine with the air cleaner
element removed. The air cleaner element notonly filters intake air but also stops flames ifthe engine backfires. If the air cleaner elementis not installed when the engine backfires, youcould be burned.
Replacing the air cleaner element
Non-turbo models
Replace the air cleaner element according to the
maintenance schedule in the “Warranty and Mainte-
nance Booklet ”. Under extremely dusty conditions,
replace it more frequently. It is recommended that
you always use genuine SUBARU parts.

CAUTION
Never use engine coolant as washer fluid be-
cause it could cause paint damage. Replacement of windshield wiper blades
Grease, wax, insects, or other material on the wind-
shield or the wiper blade results in jerky wiper
operation and streaking on the glass. If you cannot
remove the streaks after operating the windshield
washer or if the wiper operation is jerky, clean the
outer surface of the windshield (or rear window) andthe wiper blades using a sponge or soft cloth with a
neutral detergent or mild-abrasive cleaner. After
cleaning, rinse the windshield and wiper blades with
clean water. The windshield is clean if beads do not
form when you rinse the windshield with water.
CAUTION
Do not clean the wiper blades with gasoline or a solvent, such as paint thinner or benzene. This will cause deterioration of the wiperblades.
If you cannot eliminate the streaking even after fol-
lowing this method, replace the wiper blades using
the following procedures:
1. Raise the wiper arm off the windshield.
