Getting started Driving Intermittent wiping i Intermittent wiping is interrupted when the vehicle is at a standstill and a front door is opened. This protects persons getting into or out of the vehicle from being sprayed. Intermittent wiping will be continued when all doors are closed and the gear selector lever is in drive position D or reverse gear R or the wiper setting is changed using the combination switch Single wipe Press combination switch briefly in direction of arrow 1 to the resistance point. The windshield wipers wipe one time without washer fluid. Wiping with windshield washer fluid Press combination switch in direction of arrow 1 past the resistance point. The windshield wipers operate with washer fluid. ! Do not leave windshield wipers on an 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. ! If you have set intermittent wiping, dirt on the surface of the rain sensor or optical effects may cause the windshield wipers to wipe in an undesired fashion. This could then damage the windshield wiper blades or scratch the windows. You should therefore switch off the windshield wipers when weather conditions are dry. The intermittent wiping interval is dependent on the wetness of the windshield. Turn the combination switch in direction of arrow 2 to position I. After the initial wipe, pauses between wipes are controlled by the rain sensor. i To prevent smears on the windshield or noisy/chattering wiper blades, wipe with windshield washer fluid every now and then even when it is raining. For information on filling up the washer reservoir, see "Windshield washer system and headlamp cleaning system" ( page 257). 53
