WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice:
If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
Van Models
The air cleaner/filter assembly may
have an air cleaner/filter restriction
indicator that shows when the

needs to be serviced.
The air cleaner/filter restriction
indicator is located on the air
