Engine Air Cleaner/Filter
Notice: If you spray water into the engine air
cleaner/filter intake and water enters the engine air
cleaner/filter housing, as shown in the illustration,
you could damage your vehicle’s engine. The repairs
would not be covered by your warranty. Do not
spray water into the engine air cleaner/filter intake
and/or housing.
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, you
should inspect the air cleaner/filter at every oil change
and replace it at the first oil change after 100,000 miles
(160 000 km). See Scheduled Maintenance on
page 6-4 for more information.
