Air Cleaner/Filters
Inspect the air cleaner/filters at the Maintenance II
intervals and replace them at the first oil change after

Maintenance on page 7-4 for more information.

filters at each engine oil change.
How to Inspect the Engine
Air Cleaner/Filters
To inspect the air cleaner/filters, remove the filters from
the vehicle and lightly shake the filters to release
loose dust and dirt. If the filters remain caked with dirt,
new filters are required.
To inspect or replace the filters, do the following:
1. Flip the clasps on the top of the engine air
cleaner/filter cover forward to unlatch the cover.
2. Lift the front of the cover at an angle and remove.
This is necessary due to the four tabs located on
the rear of the cover.
3. Remove the engine air cleaner/filter element and
any loose debris that may be found in the air
cleaner base.
4. Inspect or replace the filter.
5. Repeat the procedure for the second air cleaner/filter.
