63 02 03 007 Adaptive Headlight - Continued


National-market version

The options "Daytime driving lights" and "Manual headlight beam throw adjustment" are available in certain countries. Vehicles with manual headlight beam throw adjustment do not have adaptive headlights. This is because vehicles with manual headlight beam throw adjustment have low-beam halogen headlights. Adaptive headlights (optional equipment 524) are only available in conjunction with optional equipment 522 "Xenon dipped and main-beam headlights".

Switching on adaptive headlights in conjunction with daytime driving lights function

The optional equipment "daytime driving lights" (Northern Europe and Canada) means that

Low-beam headlights and side lights (E70, E92, E93: daytime driving lights) are always switched on:

- Light switch in position "2"
- Terminal 15 ON


The automatic headlight beam throw adjustment is active (actuated by the control unit for adaptive headlights).

If terminal 15 is switched off, the low-beam headlights and the side lights are automatically switched off as well.

The light switch must also be set to position "A" with the optional equipment "Daytime driving lights". The control unit for adaptive headlights is then in standby.

System functions for optional equipment Daytime driving lights when the light switch is set to position "A":

- If the vehicle is encoded with the optional equipment "Daytime driving lights" (end of line), the light switch can remain in position "A" at all times.

When terminal R is switched on, the side lights, parking lights and number-plate lights are switched on.

As soon as terminal 15 is switched on, the low-beam headlights are also switched on.

- When the low-beam headlights are switched on, the control unit for adaptive headlights is activated (for automatic headlight beam throw adjustment).

- The indicator light on the light switch lights up and indicates the system's operational readiness.

- The adaptive headlights turn when the vehicle is stationary if the steering wheel angle is turned (to the right only).

- The headlights are moved when the vehicle corners if the rain/light sensor identifies darkness.

The switch-on conditions for the adaptive headlights in conjunction with optional equipment "Daytime driving lights" are as follows:

- The vehicle must be encoded with the optional equipment "Daytime driving lights" (end of line)

- The light switch must be in position "A"

- Terminal 15 must be switched on and reverse gear must not be engaged

- Rain/light sensor must identify darkness
