The engine air cleaner/filter is located in the center of the engine compartment.

If you have a diesel engine, you will have a restriction indicator that lets you know when the engine air cleaner/filter needs to be serviced. If you have a gasoline engine, you may have on also. If you don't, see Scheduled Maintenance to determine when to replace the engine air cleaner/filter.

If equipped, the restriction indicator will be located in the engine compartment near the engine air cleaner/filter, on the passenger's side of the vehicle.

When the yellow indicator reaches the red ring in the sight glass, it's time to service the engine air cleaner/filter.

After the engine air cleaner/filter is properly serviced, the indicator can be reset by pressing the button on top of 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.

For more information regarding checking your restriction indicator, see Part B: Owner Checks and Services.

Your vehicle may be equipped with an optional instrument panel mounted air filter restriction indicator. See Air Filter Restriction Indicator.
