Engine Air Cleaner/Filter
See Engine Compartment
Overview on page 5-12 for
the location of the
engine air cleaner/filter and
the air filter restriction
indicator, if equipped.
When to Inspect the Engine Air
Cleaner/Filter
If your vehicle is equipped with an air filter restriction
indicator, it lets you know when the engine air cleaner/
filter needs to be replaced. On vehicles with a restriction
indicator, you should inspect the air filter restriction
indicator at every oil change and replace the engine air
cleaner/filter when the indicator tells you to.
On vehicles without an air filter restriction indicator,
inspect the air cleaner/filter at the Maintenance
II
intervals and replace it at the first oil change after each
50,000 mile (83 000 km) interval. See Scheduled
Maintenance on page 6-4 for more information. If you
are driving in dusty/dirty conditions, inspect the filter
at each engine oil change.
