2020 Defender



The Adaptive Driving Beam (ADB) system cannot be relied upon to activate or deactivate high beam in all possible circumstances. The driver remains responsible for the correct use of the headlights at all times. Incorrect use of the headlights may cause an accident, potentially resulting in serious injury or death.


The forward-facing sensors are mounted on the rear of the rear-view mirror. Keep this area of the vehicle clean and free from obstructions, e.g., stickers, debris, mud, snow, or ice. Failure to do so can lead to accidents, potentially resulting in serious injury or death.

ADB activates automatically once the vehicle's speed reaches 40 km/h (25 mph) and the camera does not detect an urban environment. ADB automatically deactivates when the vehicle's speed slows to 24 km/h (15 mph), when ambient light exceeds a predetermined level or when the gear selector is in Reverse (R).

ADB is defined as a system that evaluates the road scene ahead of the vehicle. ADB automatically adapts the light distribution according to the position of the preceding and oncoming traffic. ADB is enabled when the lighting control is in the AUTO position and the ambient light level is below a predetermined level.


When ADB is active, the blue high beam indicator lamp remains illuminated, as the headlights will deploy partial or full high beam at this time. See HIGH BEAM (BLUE).

The driver can disable and re-enable the ADB system at any time via the touchscreen:

  1. Touch the settings icon¹ from any screen.

  2. Touch the ALL soft key.

  3. Touch Vehicle.

  4. Touch Exterior Lights.

  5. Adaptive Driving Beam: Toggle on or off.

  6. Touch the exit icon², after selection, to return to the previously displayed screen.

Pull and release the lighting control to manually override to dipped beam from ADB. The instrument panel warning lamp illuminates.

Push and release the lighting control to return to ADB. The instrument panel warning lamp illuminates. See DIPPED BEAM (GREEN).

Repeated pushing of the lighting control toggles the operation of the high beam between automatic and manual.

Rotate the lighting control to the dipped beam position to switch the ADB system off.

The following may affect operation of the ADB system:

  • Highly reflective road signs.

  • Dimly lit road users, e.g., cyclists or pedestrians.

  • Adverse weather conditions, e.g., rain or fog.

  • A dirty or obscured sensor.

  • A dirty, damaged, or misted windscreen.

  • Oncoming vehicles, partially obscured by a central motorway barrier.

  • An icy or frosted windscreen.
