How do I activate the auto hold function in my Audi A5?

I just got a new Audi A5 and I heard it has an auto hold function. How do I activate it and what is its purpose?

The auto hold function can be activated by pressing the 'auto hold' button located next to the gear shift. It is designed to keep your vehicle still when stopped in traffic or on an incline.

To activate the auto hold function, simply press and hold the brake pedal for a few seconds. It will activate automatically once the brake is released. This feature can help prevent fatigue when stopped in traffic for long periods of time.

Make sure you have your seatbelt on when trying to activate the auto hold function. It will not work if you do not have your seatbelt fastened. It's a safety feature designed to prevent the vehicle from moving if the driver is not properly restrained.
