Air Filter
The vehicle has a passenger
compartment particulate air filter.
It is located in the engine
compartment, below the air inlet
grille on the passenger side.
The filter traps most of the pollen
from air entering the climate control
system. It needs to be changed
periodically to ensure system
performance. For information on
how often to change the passenger
compartment air filter, see
Scheduled Maintenance on
page 11‑2.
To change the passenger
compartment air filter:
1. Turn off the ignition when the
windshield wipers are in the up
position.
2. Raise the vehicle hood.
3. Pull back the hood weatherstrip
from the passenger side of the
vehicle halfway to center.
4. Remove the air inlet grille
retainers.
5. Lift the air inlet grille and
disconnect the washer hose at
the quick-connect.
6. Remove the air inlet grille.
7. Remove the water deflector
plate.
8. Remove the old passenger
compartment air filter.
9. Reverse the steps to install the
new air filter.
For best climate control system
performance, reinstall the air filter.
For the type of filter to use, see
