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.
To inspect the air cleaner/filter, remove the filter from
the vehicle and lightly shake the filter to release loose
dust and dirt. If the filter remains caked with dirt, a new
filter is required.

1. Remove all three screws and carefully remove the
filter cover.
