The Dynamic Cruise Control is similar to all newer BMWs. Essentially it incorporates braking functions and is close enough to the Active Cruise, except without the radar.

As y'all discovered, you can brake fairly moderately using the cruise stalk to decel. The brake lights will illuminate and the brakes will engage until you release the stalk.

The system will also brake on downhill gradients should the vehicle begin to coast too quickly. For example, if you set the speed at 60km/h and you descend a hill, it will first release the throttle and coast via engine braking and the torque converter lockup. If the vehicle continues to speed up, it will apply the brakes gently to retain the 60km/h setting.

The system also will brake individual wheels gently should you go around a bend too quickly. When the sensors determine that the yaw-rate around a curve exceeds a threshold, it will brake the vehicle. Best way to try this out is on a cloverleaf offramp, should road and traffic conditions permit.
