FERNLICHT-ASSISTENT (AHBA)

NOTES

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.

NOTES

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

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.

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

The instrument panel warning lamp illuminates when AHBA is selected. See FERNLICHT-ASSISTENT (AHBA) (GRÜN).

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).

To manually select high beam, move the lighting control to the high beam position, as normal. To return to AHBA operation, 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 (2). AHBA cancels. To return to AHBA operation, push the lighting control to the high beam position (1) and then return it to the central position.

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

The AHBA system can be disabled or enabled via the Vehicle settings instrument panel menu. See INSTRUMENTENTAFEL MENÜ.

The hand of traffic can also be selected within the instrument panel menu. As default, this is set to be opposite the hand of drive, so if the vehicle is Left Hand Drive (LHD), the hand of traffic is Right Hand Drive (RHD).

NOTES

For vehicles fitted with a navigation system, for each ignition cycle, the hand of traffic resets. The hand of traffic resets according to the region in which the vehicle is being driven.

The following may affect the operation of the AHBA 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.

NOTES

Make sure to defrost the windscreen during winter conditions.
