Lighting for the display and W-key of the selector lever of the automatic!

Moin dear friends and the forum! Unfortunately I still have a small problem! If I set the ignition key to position II and make stand lighting, I can see the illumination of the display clearly and brightly at the selector lever for the automatic. One can see where the selector lever is at the moment, namely on P. What interests me, is the W key to the right of the selector lever. 1. Is the W key also illuminated? 2. If yes! How do you open this entire display to change lamps? 3. Which lamps are these? Many greetings from Torsten P.S. To explain the W key: the W key is called winter start-up aid. In the case of ice and snow smoothness, an automatic driver has to press the W button because the automatic drives off with the 3rd gear and because the tires can then drive better with great power and little gas pedal.
