How do I activate the night vision feature in my Audi A8?

I read that the Audi A8 has a night vision feature but I can't seem to figure out how to activate it. Is there a specific button or setting I need to use?

To activate the night vision feature in your Audi A8, press the 'View' button on your steering wheel and select 'Night Vision' from the on-screen menu. The display will then use infrared technology to show you objects in front of the car that may not be visible with the headlights alone.
