Courtesy Wipe
WARNING: This page is about a different car, the 2017 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
When the windshield washer is requested, a few seconds after the windshield wash cycle has completed, an additional wipe of the windshield occurs to clear any washer solvent remaining on the windshield.
The courtesy wipe feature can be configured on/off using the message center.
