How can I adjust the head-up display in my Audi A8?

I recently purchased an Audi A8 and have been trying to adjust the head-up display. Can anyone provide instructions on how to do this properly?

To adjust the head-up display in your Audi A8, first locate the button on the lower left side of your steering wheel. Press and hold this button until the display illuminates. Then, using the rotary knob on the lower right side of the steering wheel, adjust the display to your desired height and angle.

One way to adjust the head-up display in your Audi A8 is to use the MMI (Multi Media Interface) system. Simply go to the settings menu and select 'Display' then 'Hud'. From here, you can adjust the brightness and vertical position of the display.
