The 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.

The Auto High Beam Assist (AHBA) feature automatically selects and deselects high beam in following specific conditions:

  • Road lighting.

  • The absence of other vehicle’s lights.

The system is only active when the ambient light drops below a predetermined level.

For AHBA to become operational, the lighting control must be in the AUTO position, with dipped beam headlights selected.

The instrument panel warning light illuminates when AHBA is selected. See AUTO HIGH BEAM ASSIST (AHBA) (GREEN).

AHBA 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).

To manually select high beam, move the lighting control to the high beam position, as normal. To return to AHBA, move the lighting control back to the central position.

To manually override to dipped beam from high beam, pull the lighting control to the flash position. AHBA is canceled. To return to AHBA, push the lighting control to the high beam position and then return it to the central position.

To switch AHBA off, turn the lighting control from AUTO to headlights.

AHBA can be disabled or enabled via the Vehicle Settings instrument panel menu. See INSTRUMENT PANEL MENU.

The hand of traffic can also be selected depending on the side of driving, within the instrument panel menu.

The following may affect the operation of AHBA:

  • 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 fogged windshield.

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

  • An icy or frosted windshield.


Make sure to defrost the windshield during winter conditions.


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