Inspect the air cleaner/filter at every oil change and replace at the first oil change after 25,000 miles (40,000 km).

To inspect the air cleaner/filter remove the filter from the vehicle and lightly shake filter to release loose dust and dirt. If the filter remains "caked" with dirt, a new filter is required.

See Engine Compartment Overview for location of air cleaner/filter.

1. To check or replace the engine air cleaner/filter do the following:

Loosen the two clips on the top of the engine air cleaner/filter housing and lift the filter cover tabs out of the housing.

2. Push the filter cover housing toward the engine.
3. Pull out the filter.
4. Check or install a new engine air cleaner/filter. See Maintenance Replacement Parts .
5. To reinstall the cover, position the tabs through the slots on the housing. A notch on the sides of the filter cover will indicate the correct engagement. Reinstall the two clips on the top of the housing when you are finished.

Refer to the Maintenance Schedule to determine when to replace the air filter.

See Scheduled Maintenance .

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 the engine, which will damage it. Always have the air cleaner/filter in place when you are driving.
