How does the Audi A1's park assist feature work?

I heard that the Audi A1 has a park assist feature but I'm not sure how it works. Can someone explain it to me?

The Audi A1 park assist feature uses sensors and cameras to scan the surroundings of your car and assist with parking in tight spaces. It can even help with parallel parking or backing into a space.

To activate park assist, simply press the button on the dashboard when searching for a parking spot. The system will automatically measure the space and guide you through the parking process with visual and audio cues.

I've personally found that using park assist has significantly reduced the stress of parking in busy areas. Just make sure to still pay attention to your surroundings and use caution while using the feature.
