2016 Discovery 4



The Reverse Traffic Detection (RTD) system is a supplement to, not a replacement for, safe driving, good observation and use of the exterior and rear-view mirrors.


The system may not be able to provide sufficient warning for vehicles approaching very quickly.


RTD is automatically disabled when a trailer is connected and when Park assist is active.

In addition to the functionality provided by the Rear camera, the RTD system provides a warning to the driver of any moving vehicle, at either side, that may pose an accident risk during a reversing maneuver.

An amber warning icon (1) will flash in the relevant exterior mirror and an audible warning will be emitted, to indicate the presence of a moving vehicle. The Rear camera screen (2) or the Parking aid screen (3) will also show a warning on the relevant side(s) of the screen. To switch between the Rear camera and the Parking aid screen, touch the camera image or the Rear camera icon accordingly.

The system can be enabled or disabled via the Instrument panel menu. See INSTRUMENT PANEL MENU. When RTD is disabled, an amber dot (4) will be displayed in both exterior mirrors.
