When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
scheduled maintenance intervals
and replace it at the first oil change
after each 80 000 km (50,000 mi)
interval. See Scheduled
Maintenance on page 11 2 for more
information. If you are driving in
dusty/dirty conditions, inspect the
filter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect or replace the engine air
cleaner/filter, do the following:
1. Unfasten the clips that hold the
cover on and remove the cover.
2. Lift out the engine air cleaner/
filter.
3. Inspect or replace the air filter.
See Maintenance Replacement
Parts on page 11 9 to determine
which filter to use.
4. Reinstall the engine air cleaner/
filter cover. Fasten the clips to
hold the cover in place.
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.
