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
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
50,000 miles (83 000 km). 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.
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
filter is required.
