Image Display - Vehicles Equipped With An Interior Auto-Dimming Mirror Display

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The liftgate must remain closed for correct operation of the rear camera system.

The parking aid camera image is displayed in the interior auto-dimming mirror glass when the transmission is placed in reverse. The interior auto-dimming mirror video display turns on when the interior auto-dimming mirror receives voltage from the reversing lamp circuit.

The camera is on any time it receives voltage (when the ignition is ON), but a video signal is only generated under certian conditions. When reverse gear is selected, the camera continuously generates a video signal. When any gear except reverse is selected, the camera turns the video signal off when the vehicle speed reaches 16 km/h (10 mph), and turns the video signal on when vehicle speed falls below 8 km/h (5 mph). The video signal is sent from the camera to the auto-dimming mirror on shielded twisted pair wires. If the camera is not configured properly, some features may be inoperative.

Vehicles equipped with the interior auto-dimming mirror display do not have any features that can be configured by the driver. The following system feature(s) are always on:
