Cleaner/Filter
For vehicles without a change indicator, inspect the air
cleaner/filter every 15,000 miles (25 000 km) and
replace the filter every 30,000 miles (50 000 km). If you
are driving in dusty/dirty conditions, inspect the filter
at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
Locate the filter change indicator (if equipped). When the
change indicator turns black or is in the red/orange
"change" zone, replace the filter and reset the indicator.
If your vehicle is equipped
with a filter change
indicator, it lets you know
when the filter needs
to be replaced.
