Passenger Compartment Air Filter
The passenger compartment air lter removes certain
odor and particles from the air including pollen and dust
particles. Reductions in air ow, which may occur
more often in dusty areas, indicate that the lter may
need to be replaced early.
The lter should be replaced as part of the routine
scheduled maintenance. SeeScheduled Maintenance
on page 7-4for more information.
The passenger compartment air lter is located on the
passenger’s side of the engine compartment near
the battery. SeeEngine Compartment Overview on
page 6-12for more information on location.
To check or replace the air lter, do the following:
1. With the hood open, unlatch and remove the
access panel.
2. Pull the old lter out of the housing.
3. Insert the new lter into the housing. The lter should
be fully inserted with the arrows pointing up.
4. Reinstall the air lter access panel.
