How do I unlock my Audi A8's MMI touchpad?

I recently purchased an Audi A8 and I can't seem to figure out how to unlock the MMI touchpad for use while driving. Can you provide any guidance on how to unlock it?

To unlock the MMI touchpad on your Audi A8, press and hold down the volume control button for 3 seconds. This will activate the touchpad and allow you to use it while driving.

Another option is to go into the MMI settings and enable the touchpad under the 'Control Systems' menu. From there, you can also customize the sensitivity and other settings for the touchpad.

I highly recommend using the MMI touchpad while driving for a more intuitive and safer way to control your vehicle's systems. Just remember to keep your eyes on the road and use the touchpad sparingly.
