If it's like my 190 you push up on the rear of the sunroof button to tilt it up, and pull down on the button to close.

The fog lights are activated by pulling the knob out when the rotary light switch is at the parking or headlight position. Thus, you can run the foglights without the headlights being on. You can't do that with most cars- the headlights have to be on to turn on the foglights.
