List of actions controlling the illumination and extinction of the interior lights in manual mode:
The illumination of the interior lights is controlled by a central button with 3 positions and the following modes:
●forced on: the interior light bulbs are on.
●forced off: forced extinction of the interior lights forces the bulbs to be switched off regardless of the door switch
positions. Forced illumination of the light is still possible using the button.
