Why can't I activate my automatic parking system in my Audi A8?

I am trying to use the automatic parking system in my Audi A8, but it is not working. The car is not responding when I press the button to activate it. What could be causing this issue?

Make sure that the car is in a suitable position for automatic parking. It needs to be in a clear, open space with enough room for the car to maneuver.

Check if there are any obstacles or objects in the way of the parking space. The car's sensors may be detecting them and preventing the system from activating.

If the issue persists, try restarting the car's computer system. Sometimes, a simple reset can resolve technical glitches.
