Courtesy Wipe
WARNING: This page is about a different car, the 2018 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
If the windshield wiper switch is off 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 remaining fluid that remains on the windshield.
The courtesy wipe feature can be disabled using a diagnostic scan tool.
