there is a special procedure for checking
and changing the air cleaner/filter. Because this
procedure is difficult, you should have this done at
the dealership service department. Contact your

can be found in the service manual. To purchase

{CAUTION:
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. If it is not there and the engine
backfires, you could be burned. Do not
drive with it off, and be careful working on
the engine with the air cleaner/filter off.
Notice: If the air cleaner/filter is off, a backfire
can cause a damaging engine fire. And, dirt
can easily get into your engine, which will
damage it. Always have the air cleaner/filter in
place when you are driving.
