LIGHTING
|| If active main beam is deactivated while main
beam is on, the lighting is immediately reset to
dipped beam.
When active main beam is activated, the symbol
illuminates with a white glow in the driver
display.
When main beam is activated, the symbol shines
blue. This also applies for LED headlamps if the
main beam is partially dimmed, i.e. if the light
beam shines with slightly more than dipped
beam.
Car with halogen headlamps
The lighting returns to main beam about a sec-
ond after the camera sensor no longer detects
the headlamp beams from oncoming traffic or the
rear lights from vehicles in front.

Car with LED headlamps*
If the active main beam has the on/off functional-
7
ity then 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.
If the active main beam has adaptive functional-
7
ity then, unlike what happens during conven-
tional dimming, the light beam continues to illu-
minate with main beam on both sides of oncom-
ing traffic or vehicles ahead - only the part of the

Depending on the car's equipment level.

light beam that points directly to the vehicle is
dimmed.
Adaptive functionality: Dipped beam directly towards
oncoming vehicle, but continued main beam on both
sides of the vehicle.
The lighting returns to full 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.
Limitations for active main beam
The camera sensor on which the function is
based has limitations.
If this symbol is shown in the driver dis-
play, together with the message
High Beam Temporarily
unavailable , then switching between
main and dipped beam must be performed man-
ually. The rotating ring on the stalk switch can still
be in the position. The
guishes when these message are shown.
The same applies if this symbol is
shown together with the message
Windscreen sensor Sensor
blocked, see Owner's manual
Active main beam may be temporarily unavailable
e.g. in situations with dense fog or heavy rain.
When active main beam becomes available again,
or the windscreen sensors are no longer blocked,
the message goes out and the
minates.
WARNING
Active main beam is an aid for using the opti-
mum beam pattern when conditions are
favourable.
The driver always bears responsibility for man-
ually switching between main and dipped
beam when traffic situations or weather con-
ditions so require.
