How to activate the Audi A8 advanced safety features?

I recently purchased an Audi A8 and I am having trouble setting up the advanced safety features such as adaptive cruise control and lane keep assist. Can someone provide step by step instructions on how to activate these features?

To activate the adaptive cruise control on your Audi A8, first press the 'Menu' button on your MMI control panel. Then scroll to the 'Driver Assistance' menu and select 'Adaptive Cruise Control.' Follow the prompts to activate the feature and adjust your desired speed and following distance. For lane keep assist, you can activate it in the same menu under 'Lane Assist' and follow the prompts for calibration.

I have found that the easiest way to activate the advanced safety features on the Audi A8 is to use the voice command system. Simply press the voice button on your steering wheel and say 'Activate adaptive cruise control' or 'Activate lane keep assist.' The system will then guide you through the setup.
