What is Audi A8's Parking Assist feature and how does it work?

I'm interested in purchasing an Audi A8 and I've heard about the Parking Assist feature. What exactly is this feature and how does it function?

Audi A8's Parking Assist feature uses ultrasonic sensors to measure the distance between your car and surrounding objects. It then provides visual and audible feedback to help guide you into a parking spot.

The Parking Assist feature also has a 360-degree view camera system, giving you a complete view of your surroundings while parking. It's especially helpful for tight spaces or crowded parking lots.
