Maintenance and care WINDSHIELD WIPER BLADES Check the wiper blades at least twice a year or when they seem less effective. Substances such as tree sap and some hot wax treatments used by commercial car washes reduce the effectiveness of wiper blades. Checking the wiper blades If the wiper blades do not wipe properly, clean both the windshield and wiper blades using undiluted windshield wiper solution or a mild detergent. Rinse thoroughly with clean water. To avoid damaging the blades, do not use fuel, kerosene, paint thinner or other solvents. Changing the wiper blades To replace the wiper blades: 1. Pull the wiper arm away from the windshield and lock into the service position. 2. Turn the blade at an angle from the wiper arm. Push the lock pin manually to release the blade and pull the wiper blade down toward the windshield to remove it from the arm. 3. Attach the new wiper to the wiper arm and press it into place until a click is heard.
