What is the function of the self-leveling suspension system in an Audi 80?

I recently purchased an Audi 80 and noticed that it has a self-leveling suspension system, but I'm not sure exactly what this feature does. Can someone explain its purpose and how it works?

The self-leveling suspension system in Audi 80 models is designed to automatically adjust the height of the vehicle based on load and terrain conditions. This helps to maintain a consistent ride height and improves handling and stability while driving. In simpler terms, it helps to keep your car level and stable no matter the weight or surface it's on.
