What is the purpose of the Audi A2's integrated computer system?

I recently bought a used Audi A2 and noticed that it has an integrated computer system. What is the function of this system and how can I make use of it?

The integrated computer system in the Audi A2 serves as a central control unit for various features such as climate control, audio system, and navigation. It allows for easy access and customization of these features through the use of a display screen and buttons on the dashboard.

Aside from controlling various features, the integrated computer system also collects and displays information about the car's performance, fuel consumption, and maintenance needs. This can be useful in helping you keep track of your car's health and ensuring timely maintenance.
