Adaptive headlights for automatic driving lights control
The automatic driving lights control feature (option in conjunction with the rain-light sensor) switches the side
lights and dipped headlights on and off automatically.
Switch-on conditions:
•
The automatic driving lights control must be encoded in the light switch cluster or light module.
•
The light switch must be in position A" ("A" stands for automatic driving lights control and for
adaptive headlights).
•
The rain-light sensor must be installed and operational.
The rain-light sensor detects the brightness of the ambient light.
The rain-light sensor sends the following prompts to the light switch cluster or the light module:
-
Ambient brightness low: In twilight, darkness, in an underground garage or tunnel.
"Switch on dipped headlights" request
-
Ambient brightness sufficient.
"Switch off dipped headlights" request
If only the side lights are to be switched on, the light switch must be set to side lights (switch position 1).
When the light switch is set to position "A", the control unit for adaptive headlights is also activated:
•
When the automatic driving lights control function switches on the dipped headlights (e.g. at twilight), the
adaptive headlights function is notified at the same time.
The control unit for adaptive headlights then assumes control of the automatic headlight-range adjustment.
•
In addition, the signals from the rain-light sensor are also evaluated. The headlights are not turned when
the vehicle is cornering until total darkness sets in.
The message "dipped headlights on" is given individually for each headlight.
If a headlight fails, the adaptive headlights are switched off.
The front foglights are switched on in order to ensure a minimum level of illumination.
Turning lights

Light switch in position "A" ("A" stands for automatic driving lights control)
-
Rain-light sensor detects twilight or darkness (threshold exceeded)
and
-
Turn signal indicator ON (not one-touch turn signal)
-
