If you are cleaning your vehicle with the hood open, take care not to spray water directly into either end of the air cleaner/filter housing, as shown in the illustration, as this could damage your vehicle's engine.

When to Inspect the Engine Air Cleaner/Filters

Inspect the air cleaner/filters at the Maintenance II intervals and replace them at the first oil change after each 50,000 mile (83 000 km) interval. See Scheduled Maintenance for more information. If you are driving in dusty/dirty conditions, inspect the 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 engine air cleaner/filters, do the following:

  1. Pull the latches on each side of the cover to open, then move the latches up and out of the way.
  2. Push the air cleaner/filter cover toward the front of the vehicle and then pull it up and away.
  3. Inspect or replace the filter. See Maintenance Replacement Parts .
  4. Reverse Steps 1 and 2 to replace the air cleaner/filter cover.
  5. Repeat the procedure for the second air cleaner/filter.

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.
