Active high beam*
The Active High Beam function detects the
headlamp beams of oncoming traffic or the
rear lights of vehicles in front, and switches
the lighting from main beam to dipped beam.
The lighting returns to main beam when the
incoming light has stopped.
Active high beam - AHB
Active high beam (Active High Beam - AHB) is
a function which uses a camera sensor at the
top edge of the windscreen to detect the
headlamp beams of oncoming traffic or the
rear lights of vehicles in front, and then
switches from main beam to dipped beam.
The function can also take streetlights into
account.
The lighting returns to main beam about a
second after the camera sensor no longer
detects the headlamp beams from oncoming
traffic or the rear lights from vehicles in front.
Activating/deactivating
AHB can be activated when the headlamp
control's knob is in position
(provided
that the function has not been deactivated in
the menu system MY CAR), see MY CAR (p.
104).
Stalk switch and knob for headlamp control in
AUTO position.
The function can start while driving in the
dark when the car's speed is 20 km/h or
higher.
Activate/deactivate AHB by moving the left-
hand stalk switch towards the steering wheel
to the end position and then releasing. Deac-
tivation when main beam is on means that the
lights are reset directly to dipped beam.
Car with analogue combined instrument
panel
When AHB is activated the
symbol illu-
minates in the instrument's information dis-
play.
When main beam is switched on the
symbol also illuminates in the combined
instrument panel.
