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.

reset the indicator. See the steps following to replace
the engine air cleaner/filter and to reset the air filter
restriction indicator.
