The Auto High Beam Assist (AHBA) system cannot be relied upon to activate or deactivate high beam in all potential 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.

The AHBA system automatically selects and deselects high beam, under specific conditions of road lighting and in the absence of other vehicle lights. The system is only active when the ambient light drops below a predetermined level. AHBA is enabled when the lighting control is in the AUTO position.

The driver can disable and re-enable the AHBA 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. Automatic high beam assist: Toggle on or off. Toggle on to activate and view the available options.

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

The AHBA system only activates when the vehicle's speed exceeds 40 km/h (25 mph). The system deactivates when the vehicle's speed drops below 24 km/h (15 mph).

Push and release the lighting control to manually override to dipped beam from high beam. Rotate the collar to AUTO to return to AHBA. The instrument panel warning lamp illuminates. See AUTO HIGH BEAM ASSIST (AHBA) (BLUE).
