This system can be used to select a desired speed that the vehicle will maintain automatically on clear roads.

To the extent possible, the system automatically adjusts the speed to a slower vehicle ahead of you.

The distance that the vehicle maintains to the vehicle ahead of you can be varied.

For safety reasons, it depends on the speed.

To maintain a certain distance, the system automatically decelerates, applies the brakes lightly, or accelerates again if the vehicle ahead begins moving faster.

If the vehicle ahead of you brakes to a halt, the system is able to detect this within the given system limits. If the vehicle ahead of your drives away again from a halt, your vehicle is able to accelerate if operated accordingly.

Even if some time passes before the vehicle drives away again, the BMW can still be accelerated automatically and simply.

As soon as the road is clear, it accelerates to the desired speed.

The speed is also maintained on downhill gradients, but may not be maintained on uphill slopes if engine power is insufficient.
