Controls in detail Good visibility Windshield wipers Information on the windshield wipers ( page 47) is found in the "Getting started" section. Intermittent wiping ! To prevent damage of the windshield wipers, do not leave the wiper switch in intermittent setting, when the vehicle is taken to an automatic car wash or when cleaning the windshield. 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 when wiping occurs on a dry windshield! i Intermittent wiping is interrupted when the vehicle is at standstill and a front door is opened. Windshield wipers without rain sensor At speeds of approximately 105 mph (170 km/h) the wiper switches automatically to continuous wiping. Always obey local speed limits. Windshield wipers with rain sensor* The rain sensor controls the windshield wipers automatically according to the amount of water on the windshield. Switch ignition on. Set the wiper switch to position 1 ( page 47). One initial wipe, pauses between wipes are automatically controlled by the rain sensor monitoring wetness of windshield. ! If leaves, snow, etc. block the windshield wipers, the wiper motor turns off. For safety reasons, withdraw key from steering lock. Remove blockage. Turn the windshield wipers on again. If windshield wipers fail to function at all in switch position 1, set the wiper switch to the next highest wiper speed. have the windshield wipers checked at the nearest authorized Mercedes-Benz Light Truck Center. i When intermittent wiping is on and the key is turned from position 1 to position 2 in the steering lock ( page 33), and kept in that position for longer than 2 seconds, the wipe interval will be set to approximately 5 seconds. 122
