When to Inspect the Engine Air Cleaner/Filter
Inspect the air cleaner/filter at the Maintenance II intervals and replace it at the first oil change after each 50,000 mile (80 000 km) interval. See Scheduled Maintenance for more information. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change.
