Engine Air Cleaner/Filter
SeeEngine Compartment
Overview on page 5-14for
the location of the
engine air cleaner/lter and
the air lter restriction
indicator, if equipped.
When to Inspect
If your vehicle is equipped with an air lter restriction
indicator, it lets you know when the engine air cleaner/
lter needs to be replaced. On vehicles with a restriction
indicator, you should inspect the air lter restriction
indicator at every oil change and replace the engine air
cleaner/lter when the indicator tells you to.On vehicles without an air lter restriction indicator,
inspect the air cleaner/lter at the MaintenanceII
intervals and replace it at the rst oil change after
50,000 miles (83 000 km). SeeScheduled Maintenance
on page 6-4for more information. If you are driving in
dusty/dirty conditions, inspect the lter at each engine
oil change.
How to Inspect
Vehicles with an Air Filter Restriction
Indicator
Locate the air lter restriction indicator on the engine air
cleaner/lter cover. When the indicator turns black or
is in the red/orange “change” zone, replace the lter and
reset the indicator. See the steps following to replace
the engine air cleaner/lter and to reset the air lter
restriction indicator.
Vehicles without an Air Filter Restriction
Indicator
To inspect the air cleaner/lter, remove the engine air
cleaner/lter from the vehicle using the steps following.
When you have the engine air cleaner/lter removed,
lightly shake it to release loose dust and dirt. If the
engine air cleaner/lter remains caked with dirt, a new
lter is required.

Replacing the Engine Air Cleaner/Filter
and Resetting the Air Filter Restriction
Indicator
1. Locate the air cleaner/lter assembly on the
front corner of the engine compartment on the
passenger’s side of the vehicle.
2. Loosen the screws on the cover of the housing and
lift up the cover.3. Remove the engine air cleaner/lter from the
housing. Care should be taken to dislodge as
little dirt as possible.
4. Clean the engine air cleaner/lter sealing surfaces
and the housing.
5. Inspect or replace the engine air cleaner/lter.
6. Reinstall the cover and tighten the screws.
7. Reset the air lter restriction indicator, if equipped,
by pressing the top button on the indicator.
