Your Maintenance Schedule, in the back pocket of this Owner's Manual, tell you when to replace the air filter. If you want to replace the air cleaner element yourself, here's how to do it.
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.
Refer to Scheduled Maintenance to determine when to replace the air filter.
To replace the engine air cleaner/filter, do the following:
If the air filter element is dirty, you should replace it. If it is only dusty, it may be cleaned by blowing compressed air through it from the clean side.
Make sure that you are away from the engine compartment when cleaning the air filter with compressed air.
