Deysha's answer seems entirely accurate to me. The transmission has 3 modes - Drive, Sport, and Selectshift. Only Selectshift displays what gear you are in.
Selectshift is activated by first putting the transmission from Drive into Sport mode with the gear shift lever, then pressing the toggle buttons on the gear shift knob to manually "select shift" your gear.
I know, we are talking semantics and I'm being picky. But, before I'd driven one, I was a little confused by this. Hope this helps out my fellow noobs.
Thank you, guys!
