WIPER BLADES CAUTION ● After wiper blade replacement, return the wiper arm to its original position. Otherwise it may be damaged when the engine hood is opened. ● Make sure the wiper blade contacts the glass. Otherwise, the arm may be damaged from wind pressure. ADI0721 CLEANING If your windshield is not clear after using the windshield washer or if a wiper blade chatters when running, wax or another material may be on the blade or windshield. Clean the outside of the windshield with a washer solution or a mild detergent. Your windshield is clean if beads do not form when rinsing with clear water. Clean the blade by wiping it with a cloth soaked in a washer solution or a mild detergent. Then rinse the blade with clear water. If your windshield is still not clear after cleaning the blades and using the wiper, replace the blades. REPLACEMENT 1. Pull the wiper arm up. 2. Lift the tab, then remove the wiper blade. 3. Attach the new wiper blade to the wiper arm until a click sounds. 7-17
