AUTO HIGH BEAM ASSIST (AHBA)

WARNING

The Auto High Beam Assist (AHBA) 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 injury or death.

WARNING

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 causing serious injury or death.

NOTES

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 as follows:

  1. Select Exterior lighting in the Vehicle settings menu, via the instrument panel. See INSTRUMENT PANEL MENU.

  2. Select Headlights high beam.

  3. Select Auto High Beam ON or OFF.

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

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 colored and emergency service vehicles.

  • 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 windshield.

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

  • An icy or frosted windshield.
