Automatic wipe

The automatic wipe function can be activated by pressing the axial button from status "terminal R ON". The LED on the wiper switch indicates that the function is active. A one-off wipe function (acknowledgement wipe) is additionally started. The acknowledgement wipe is also initiated when the wipe interval is increased by means of the wiper-stage switch but not when the wipe interval is decreased.

The rain/lights/solar/condensation sensor initiates wipe requests according to the heaviness of the rain. The junction box electronics analyze the signal from the rain/lights/solar/condensation sensor every 20 ms. For this, the junction box electronics request the relevant signal values and execute the windscreen wipe according to the wipe request.

With the automatic wipe function, the wipe speed depends on the information from the rain/lights/solar/condensation sensor, i.e. continuous wipe stage 1 or stage 2 may be initiated depending on the rain intensity.
