2016 S63...a few Q

1) What does the "P" in a blue box mean that shows up bottom left of the tack that goes on/off? Can't find in the manual. Btw, Owner's Manual is terrible!
2) I guess you can't have the ECO default to off? One needs to press that button to "off" each time you start?
3) How do you turn off the Radio/Media Music? I a see to do is "Mute" how do you turn it "Off"...can't even find that in the Manual!
2. Correct, can't default it to off but I believe putting the car in Sport turns it off automatically
