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.


Make sure that the forward-facing sensors on the rear of the rear-view mirror are not blocked or obstructed.


The AHBA feature is a reactive system, not a predictive system. Its automated function relies on a clear view of other vehicle light sources, at which point the system will react.

The AHBA system automatically disables high beam in the presence of other road users and street lit environments, enabling high beam in their absence. 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 and AHBA is selected within the instrument panel.

The driver can disable and re-enable the AHBA system at any time:

  • Select Exterior Lighting in the Vehicle Settings menu via the instrument panel.

  • Select Headlights High Beam.

  • Select Auto High Beam ON or OFF.

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 low 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) (GREEN)

Push and release the lighting control to manually select high beam. Rotate the lighting control to AUTO to return to AHBA.

The following situations may limit the performance of AHBA:

  • Highly reflective road signs.

  • Highly reflective vehicles, e.g., brightly coloured and emergency service vehicles.

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

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

  • Dirty or obscured sensor.

  • Dirty, damaged, or misted windscreen.

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

  • An icy or frosted windscreen.
