How to enable automatic parallel parking in Audi A6?

I recently purchased an Audi A6 and was wondering how to enable the automatic parallel parking feature. I've read the manual but still can't figure it out. Can someone provide step-by-step instructions?

To enable automatic parallel parking in your Audi A6, first make sure the feature is available in your model and trim level. Next, put the car in Drive mode and press and hold the Parking button on the center console. Follow the prompts on the display screen to confirm your selection and the car will begin searching for a suitable parking spot. Once a spot is found, follow the instructions on the screen to complete the parking maneuver.
