How does the adaptive cruise control work in a 2019 Audi A1?

I am considering buying a 2019 Audi A1 and I am curious about the adaptive cruise control feature. How does it work and what are its limitations?

The adaptive cruise control system in the 2019 Audi A1 uses radar and sensors to maintain a safe distance from the vehicle in front of you. It can adjust your speed and even bring the car to a complete stop if necessary. However, it is important to note that it is not a fully autonomous driving system.
