Engine Air Cleaner/Filter
The engine air cleaner/filter
is located in the center of
the engine compartment.

Air Cleaner/Filter
If your vehicle has an
air cleaner/filter change
indicator, inspect the
indicator at every oil
change and replace the
filter when the indicator
tells you to.
For vehicles without a change indicator, inspect the air
cleaner/filter at every oil change and replace the
filter at the first oil change after 25,000 miles
(40 000 km).

careful working on the engine with the air
cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre can
cause a damaging engine re. And, dirt can
easily get into your engine, which will damage it.
Always have the air cleaner/lter in place when you
are driving.
