Now-there is some info about dimmer and lighting - still nothing bout WHERE that bloody sensor is hidden(IF it's there - mine defo doesn't have it-dark graphics) in control panel:
Lighting
The lighting for the Comfort display is activated at the Key-ON and dimmed at night (night mode); the lighting for the Matrix display is activated and dimmed at the Key-ON (day mode and night mode).
The lighting of the graphics and the pointers, on the other hand, is activated and dimmed at night (night mode).
If there are failure messages (except for "Ice danger" and feedback messages), the brightness of the display is automatically set at the maximum daytime value even in nightime conditions.
Brightness sensor (only for versions with bright graphics) The control panels with bright graphics have a brightness sensor to management the vehicle on board lighting appropriately. The brightness sensor is incorporated in the control panel.
The control panel distinguishes daytime (day mode) from nightime (night mode) conditions depending on the status of the side lights (activated / deactivated) and the sensor signalling.
If there is no sensor (versions with dark graphics) the control panel distinguishes daytime from nightime conditions depending on the side lights status only.
Dimming For the Comfort panel in daytime conditions (day mode), the display is lit to 100% and the brightness cannot be adjusted (dimmed). The adjustment is only possible in nightime conditions (night mode).
The brightness of the display can be adjusted (dimmed) for the Matrix panel in daytime conditions as well.
In nightime conditions, the brightness of the display is automatically dimmed to a pre-set level and the graphics and the pointers light up. The driver can adjust the brightness of the panel, the radio, the Connect Nav+ and the automatic climate control (to 8 settings) via an item in the setup menu.
The lighting brightness cannot be reduced to zero.
If the brightness is adjusted the display shows the specific message and the brightness adjustment symbols come on/go off. With all the symbols lit up, the brightness is at the maximum level.
The effect of the adjustment is immediately visible.
Hope it will solve your question lyubohar ;-)
