Use the procedure listed below to replace the passenger
compartment air filter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them off
again when the wipers are in the out-wipe position.
The wipers will be straight up and down on the
windshield.
This will allow you access to the leaf screen under
which is located the passenger compartment
air filter.
3. Open the hood to access the engine compartment.
See Hood Release on page 5-11 for more
information.
4. Remove the four screws that hold the leaf screen in
place and lift off the screen by lifting and sliding
toward the center of the vehicle.
5. Pull out on the two tabs located on each end of the
filter cover.
6. Lift the filter cover off by pulling it straight upward.
7. Remove the old filter and insert a new one.
Make sure the arrow on the filter is pointing toward
the passenger compartment.
See Normal Maintenance Replacement Parts on
