Engine Air Cleaner/Filter
See
Overview on page 5-14
for
the location of the engine
air cleaner/filter and the air
filter restriction indicator, if
the vehicle has one.
When to Inspect the Engine
Air Cleaner/Filter
If your vehicle has 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
Maintenance on page 6-4
for more information. If you
are driving in dusty/dirty conditions, inspect the filter
at each engine oil change.

restriction indicator.

filter is required.
