See Engine Compartment Overview for location of engine air cleaner/filter and change indicator (if equipped).

When to Inspect

If your vehicle is equipped with a filter change indicator it lets you know when the filter needs to be replaced. Vehicles with a restriction indicator, inspect the air cleaner/filter at every oil change and replace the filter when the indicator tells you to. Vehicles without a change indicator, inspect the air cleaner/filter at every oil change and replace it at the first oil change after 25,000 miles (40 000 km).

How to Inspect

Locate the filter change indicator. When the change indicator turns black or is in the red/orange "change" zone, replace the filter and reset the indicator. 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.

To inspect and replace the filter and reset the indicator (if equipped), do the following:

  1. Loosen the screws on the cover of the housing and lift up the cover.
  2. Remove the air cleaner/filter from the housing. Care should be taken to dislodge as little dirt as possible.
  3. Clean the filter sealing surface and the housing.
  4. Install the new engine air cleaner/filter.
  5. Reinstall the cover and tighten the screws.
  6. Reset the filter change indicator, if equipped, by pressing the top button on the indicator.

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.
