Vehicle Care 10-35 Wiper Blade Replacement Windshield wiper blades should be inspected for wear or cracking. See Maintenance Schedule on page 11‑3. Replacement blades come in different types and are removed in different ways. To remove the wiper blade: 1. Pull the windshield wiper arm connector away from the windshield. 3. Install the new blade onto the arm connector and make sure the grooved areas are fully set in the locked position. For the proper type and size, see Maintenance Replacement Parts on page 11‑15. Headlamp Aiming Headlamp aim has been preset and should need no further adjustment. If the vehicle is damaged in a crash, the headlamp aim may be affected. If adjustment to the headlamps is necessary, see your dealer. Glass Replacement If the windshield or front side glass must be replaced, see your dealer to determine the correct replacement glass. 2. Squeeze the grooved areas on each side of the blade, and turn the blade assembly away from the arm connector.
