How to Enable and Use Audi A7 Night Vision Assist?

I am having some difficulty understanding the night vision assist feature on my Audi A7. Can someone please explain how to enable and use it properly? Thanks!

To enable Audi A7 night vision assist, first open your car's menu and select 'Night Vision' under the 'Driver Assistance' tab. Then select 'Activate' to turn it on. Once enabled, the feature will display a clear image of pedestrians and animals in low-light conditions, helping you avoid potential hazards on the road.

First, make sure your car's headlights are on. Then, while driving at speeds above 20mph, press the 'NV' button located on the end of the turn signal lever to activate night vision assist. Keep in mind that the feature only works in temperatures above 25 degrees Fahrenheit, and may not detect objects if they are too far away or moving too quickly.
