2006 Volkswagen Passat multi-functional display or combi-instrument

Hello. I have another question. I need your kind help (i) how do I get the service to display without resetting it accidently?What am I doing wrong? (ii) I also have a large mutli-functional display screen on the dashboard which shows the warning lamps in the upper part and miles left in the fuel tank, temperature, etc. in the lower part (when the ignition is on/engine off in Position 2). However, following the manual's instructions, I have tried using the extra buttons on the wiper and rocker switch to bring up the menu and settings for things like winter tyres, next service, coming/leave home functions, etc in the upper display. However, nothing happens. Please help! (iii) do I have front fog lights on my car. I have the symbol indicated on the round lights dial (showing all external lights and rear fog lights) but i cannot push the dial to the front fog symbol without breaking the dial. Maybe I don't have front fog lights but why have the symbol on the dial? (iv) my front passenger spot light glass is cracked. Any suggestions where I can get a cheap replacement? Thank you.
