Automatic alignment of the main-beam assistant
Automatic main-beam headlight switch-off when oncoming traffic is detected
The light cone of the main-beam headlights has a range of about 400 m. The image sensor can detect other
light sources within a range of about 1000 m. This ensures that the image sensor detects oncoming vehicles
before their drivers can be dazzled by the light cone of the main-beam headlights.
When the image sensor detects an oncoming vehicle, the FLA control unit sends a switch-off recommendation
to the light module or footwell module. The light module or footwell module switches the main-beam headlights
off.
Automatic main-beam headlight switch-off when vehicle detected ahead of the car
When the image sensor detects a vehicle ahead, the FLA control unit sends a switch-off recommendation to the
light module or footwell module. The light module or footwell module switches the main-beam headlights off.
Automatic main-beam headlight switch-off when adequate ambient lighting is detected
When the image sensor detects an environment in which ambient lighting is adequate, the FLA control unit
sends a switch-off recommendation to the light module or footwell module. The light module or footwell module
switches the main-beam headlights off.
Adequate ambient lighting means:
•
Daylight
•
Twilight
•
Street lighting (e. g. in illuminated towns)
Automatic main-beam headlight switch-on
If there is no reason for the lights to be dipped, the light module or footwell module switches the main-beam
headlights on. The bi-xenon headlights are switched to full beam.
Displays in the instrument cluster
The FLA indicator light lights up in the instrument cluster as soon as the main-beam assistant is activated (blue
on the BMW 7-Series, orange on the BMW 3, 5, and 6-Series and on the X5).
The main-beam indicator light also lights up (blue) in the usual way as soon as the main-beam headlights are
switched on.
A Check-Control symbol appears (yellow) if the FLA control unit detects a system failure.

Function limitations of the main-beam assistant
The main-beam assistant can be subject to function limitations under the following circumstances:
•
Inclement weather conditions (e.g. fog)
•
Poorly lighted road users (e.g. cyclists, pedestrians)
•
Certain road signs (e.g. the warning sign for a tight bend): Reflections from traffic signs may be incorrectly
interpreted by the main-beam assistant as a vehicle driving ahead or as oncoming traffic.

•
Driving over crests and through dips

•
Certain traffic situations (e.g. tight bends, vehicles approaching from the side)
