Parking Aid Audible Alert
WARNING: This page is about a different car, the 2019 Lincoln MKZ. However, it is still accessible from the selected car via links, so may be relevant.
Audio system volume is automatically reduced when a parking aid alert tone is sounded. The alert tone frequency increases as the vehicle gets closer to an obstacle. When an object is detected within 30 cm (12 in) of the sensors, the warning tone becomes continuous. Objects detected outside the continuous tone area to the side of the vehicle generate a warning tone for 3 seconds. The warning tones are prioritized to the closest object. If the front and rear objects are located the same distance from the vehicle, the rear object is prioritized.
