~1min read

Inspect the air cleaner/filter at the scheduled maintenance intervals and replace it at the first oil change after each 80 000 km (50,000 mile) interval. See Maintenance Schedule, for more information.

If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change.
