How can I activate the stop-and-go assist function in my Audi A8?

I heard that the Audi A8 has a stop-and-go assist function, but I'm not sure how to use it. Can someone guide me on how to activate this feature? Thanks!

To activate the stop-and-go assist function, first make sure the ACC (Adaptive Cruise Control) system is turned on. Then, simply press the 'Set' button on the steering wheel and the car will take over the acceleration and braking, allowing you to comfortably navigate through congested traffic.

If you have the 'Traffic jam assist' package in your Audi A8, you can activate the stop-and-go function by pressing and holding the 'Resume' button on the steering wheel. This will enable the car to automatically accelerate, brake, and steer in stop-and-go traffic situations.
