Getting started Driving ! Vehicles with rain sensor*: Do not leave windshield wipers in intermittent setting when the vehicle is taken to an automatic car wash or during windshield cleaning. Wipers will operate in the presence of water sprayed on the windshield, and wipers may be damaged as a result. The switch should not be left in intermittent setting as the wipers will wipe the windshield once every time the engine is started. Dust that accumulates on the windshield might scratch the glass and/or damage the wiper blades when wiping occurs on a dry windshield. Switching on windshield wipers Make sure the ignition is switched on. Turn the wiper switch to the desired position 1, 2 or 3, depending on the intensity of the rain. Single wipe Press wiper switch briefly in the direction of arrow 2. The windshield wipers wipe one time without washer fluid. Wiping with windshield washer fluid Pull and hold wiper switch in direction of arrow 4. The windshield wiper operates with washer fluid. Information on filling up the washer reservoir can be found in the "Operation" section ( page 224). ! If anything blocks the windshield wipers (leaves, snow, etc.), switch them off immediately. For safety reasons, withdraw key from steering lock before attempting to remove any blockage. Remove blockage. Turn the windshield wipers on again. If windshield wipers fail to function at all in switch position 1, set the combination switch to the next highest wiper speed have the windshield wipers checked at the nearest authorized Mercedes-Benz Light Truck Center 50
