190 Maintenance CHANGING THE WIPER BLADES Replace wiper blades at least once per year for optimum performance. To replace the wiper blades: 1. Fold back the wiper arm and position the wiper blade at a right angle to the wiper arm. 2. To remove the wiper blade, press the retaining clip (A) to disengage the wiper blade, then pull the blade A down toward the windshield to remove it from the arm. 3. Install the new wiper blade on the arm and press it into place until a click is heard. Poor wiper quality can be improved by cleaning the wiper blades and windshield. Refer to Windows and wiper blades in the Cleaning chapter. To prolong the life of the wiper blades, it is highly recommended to scrape off the ice on the windshield before turning on the wipers. The layer of ice has many sharp edges and can damage the micro edge of the wiper rubber element.
