Hi guys, I've just bought a R500 D, which seems to have launch control, but I can't find any instructions for it anywhere. It's got the button (left side of steering wheel above the two stack buttons) but it's also got an additional display, to the left of the group of buttons, which looks like an additional round button but illuminates with a blue 1 when the ignition is on. Is this for the launch control? I'm told it might be for traction control, but I didn't think there ever was such a thing. The car is manual, but it just occurs to me that it's the sort of display you might have for a sequential gearbox, anyone know? Thanks
