Engine Air Cleaner/Filter
See
Engine Compartment Overview on page 5-12
for
location of engine air cleaner/filter and change indicator
(if equipped).
When to Inspect
If your vehicle is equipped with a filter change indicator
it will let you know when the filter needs to be
replaced. Inspect the air cleaner/filter every 15,000
miles (25 000 km) and replace the filter if necessary.
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
or change indicator at each engine oil change.
How to Inspect
Locate the filter change indicator. 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 filter to release loose dust and
dirt. If the filter remains “caked” with dirt, a new filter
is required.
