How do I use the adaptive cruise control in my Audi A4?

I just got my new Audi A4 and I am not sure how to use the adaptive cruise control. Can someone please explain it to me step by step?

The adaptive cruise control feature in Audi A4 allows your car to maintain a safe distance from the vehicle in front of you by automatically adjusting your speed. To activate it, simply press the ACC button on your steering wheel and set your desired speed. It's important to note that ACC only works above 20 mph.

Using the adaptive cruise control in your Audi A4 is simple and efficient. Just set your desired speed and keep your foot off the gas pedal. The car will automatically slow down if it detects a slower vehicle ahead and will accelerate back to your set speed once the road is clear.
