How do I activate the self-parking feature on my Audi A3?

I just purchased an Audi A3 and was wondering about how to use its self-parking feature. Can anyone explain to me the steps for activating this feature and any tips or best practices for using it effectively?

To activate the self-parking feature on your Audi A3, first make sure your vehicle is in a safe, open space. Then, press the button with the letter 'P' on it, located above the rearview mirror. The car will automatically search for an available parking space and guide you through the process of parking. Make sure to always be aware of your surroundings and be ready to take manual control if needed.
