I was doing a little reading of some reviews on our crossfires and found a interesting bit of info on the automatic transmission. I copied the text which reads:

"It has the usual Mercedes left-right for up-down sequential manual override, plus the same feature as found in an AMG Mercedes: hold the selector in the downchange position for a couple of seconds, and it automatically selects the gear that will give the best overtaking performance from the current speed. As for names, Mercedes's Sequentronic gives way here to AutoStick."

Sorry for posting this if it's something everyone already knew,
