You can also accomplish this with engine in park. When pushing the start/stop button, at the same time have the release button on the shifter pushed in straight line shifter, or on the gated shifter, have it pushed to the side.
I find in winter it is best to deactivate the auto wiper. Turns the system to regular delay system. Driving around in light snow/spray the sensor doesn't seem to adequately keep the window clean to my needs.
