These two tips will most likely get a "duh" from most members here but may come in handy for brand new Z owners...
1- The noise from the dash after you turn off the car then open the door is the steering wheel locking (took me a couple of days to figure out what the loud noise was).
2- Each click of the temperature control knob = 1 degree (took me another couple days to realize that one).
Then again, maybe I'm the only one who didn't figure out ^^ immediately
