How can I activate the auto hold function in my Audi A1?

I've noticed my Audi A1 has an auto hold function but I'm not sure how to activate it. Can someone please explain the process to me?

To activate the auto hold function in your Audi A1, simply press and hold the button located on the center console. This will activate the feature and allow you to release the brake pedal without the car moving. Don't worry, the auto hold function will automatically turn off when you press the accelerator pedal.
