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 page 6-15 for the correct part number for the filter. 8. Reverse Steps 1 through 6 to reinstall the cover. Steering Wheel Climate Controls There are four controls that can be programmed for use with the climate control system. The controls are located on the left side of the steering wheel. See Reconfigureable Steering Wheel Controls (SWC) on page 3-8 for more information on programming these controls. 3-33
