When activated you take your feet off the gas and brake, and the car determines the safe speed considering the steepness and surface conditions. The vehicle controls the throttle and brake, you just steer. It's a little freaky 1st time you use it!
Btw- you can press the gas to speed up, but braking deactivates it....... At least on my RR
What you are describing is HDC found in SUVs not in BMW sedans/coups. SehrSchnell was actually describing "Starting Assistant" which holds the brakes for 2 seconds when you are stopped on an uphill grade. Useful when leaving steep parking garage ramps and there is another car right behind you.
