The windshield wipers will move to the service position if you switch the ignition on briefly, switch it off again, then press the windshield wiper lever down on the steering column. Once in the service position, the base of the windshield is easily accessible for cleaning and the wipers can be moved away from the glass so that they do not freeze to the windshield. You can find more information on this feature in sections 3.1 and 3.2 of your Owner's Manual.
