How do I activate hands-free mode in my Audi A8?

I want to be able to use voice commands while driving, but I'm not sure how to activate the hands-free mode in my Audi A8. Can someone please explain the steps?

Once you've activated hands-free mode, make sure to speak clearly and try to avoid any background noise that may interfere with the system's ability to understand your commands.

To activate hands-free mode in your Audi A8, press the voice recognition button on the steering wheel and wait for the system to prompt you. Then simply speak your desired command. For example, you could say 'Call John Smith on mobile.'

You can also activate hands-free mode by saying 'Hey Audi' while driving. This will wake up the voice recognition system and you can then give your command.
