NOTE: The rain sensor is an optical measuring instrument. Contamination such as oil, grease or dust impair its correct operation. Before switching on the automatic windshield wipers, the windshield must be clean in the area of the rain sensor. 6 7 8 The rain sensor comprises an opto-electronic measuring and evaluation circuit. The sensor can calculate the amount of precipitation falling on the windshield and request that the windshield wipers are switched on. On the basis of the information provided by the rain sensor, the windshield wipers are then set to the required wipe speed. The windshield wash/wipe system will only operate if the ignition switch is in the position "I" or "II". Five wash functions are available: "Off", "Flick-wipe", "Speed 1", "Speed 2" and "Intermittent" or "Automatic wipe" (depending on the vehicle specification). In "Speed 1" or "Speed 2" mode, the wipers are operating continuously at either normal speed or fast speed.
