WARNING
Never attempt to remove the radiator cap until the engine has been shut off and has cooled
down completely. Since the coolant is under pressure, you may suffer serious burns from a
spray of boiling hot coolant when the cap isremoved.

Do not pour the coolant too quickly, as this may lead to insufficient air bleeding and trapped air in thesystem.

WARNING
Do not operate the engine with the air cleaner

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. 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.
