How can I activate the auto-hold feature in my Audi A6?

I noticed that my Audi A6 has an auto-hold button but I can't seem to figure out how to activate it. Can someone help me understand the process?

To activate the auto-hold feature in your Audi A6, first press the button labeled 'Auto-Hold' located on your center console. Once activated, the auto-hold feature will automatically hold the vehicle in a stationary position when you release the brake pedal. This is particularly convenient in stop-and-go traffic or at red lights.

The auto-hold feature in your Audi A6 is a great addition for city driving. To activate it, simply press the 'Auto-Hold' button located near your gear shift lever. Once activated, you can release the brake pedal and the vehicle will stay in place until you press the accelerator.
