Engine Air Cleaner/Filter
See Engine Compartment
Overview on page 5-12 for
location of engine air
cleaner/filter and air filter
restriction indicator
(if equipped).
When to Inspect
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
25,000 miles (40 000 km). See Scheduled Maintenance
on page 6-4 for more information.
How to Inspect
Vehicles with an Air Filter Restriction
Indicator
Locate the air filter restriction indicator on the engine air
cleaner/filter cover. When the indicator turns black or
is in the red/orange “change” zone, replace the filter and
reset the indicator. See the steps following to replace
the engine air cleaner/filter and to reset the air filter
restriction indicator.
Vehicles without an Air Filter Restriction
Indicator
To inspect the air cleaner/filter, remove the engine air
cleaner/filter from the vehicle using the steps following.
When you have the engine air cleaner/filter removed,
lightly shake it to release loose dust and dirt. If the
engine air cleaner/filter remains caked with dirt, a new
one is required.
