Adaptive Headlights For Automatic Driving Lights Control

The automatic driving lights control feature (option in conjunction with the rain-light sensor) automatically switches the side lights and dipped headlights on or off.

Switch-on conditions:

• The automatic driving lights control must be encoded (in the light module on the E60, E61, E63, E64, E65, E66, in the footwell module on the E70, E81, E87, E90, E91, E92, E93).
• The light switch must be in position "A" ("A" for automatic driving lights control and 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 module (on the E70, E81, E87, E90, E91, E92, E93: footwell 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 dawn/dusk), the adaptive headlights function is notified at the same time.

  The control unit for adaptive headlights thus assumes control of the automatic headlight - range adjustment.

• In addition, signals from the rain - light sensor are evaluated (E60, E61, E63, E64, E65, E66: by the light module; E90, E91, E92, E93: by the footwell module).

  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.
