Reductions in airow, which may occur more quickly in
dusty areas, indicate that the lter needs to be
replaced early.The lter should be replaced as part of routine
scheduled maintenance. SeeScheduled Maintenance
on page 6-4for replacement intervals. See your
dealer for details on changing the lter. To nd out what
type of lter to use, seeNormal Maintenance
Replacement Parts on page 6-13.
To access the passenger compartment air lter you
must go through the glove box.
1. Open the glove box and remove all articles from the
inside.
2. Release the glove box stops by pushing them both
outward to let the glove box drop open completely.

both ducts.
