How to Enable Night Vision on Audi A6?

I recently purchased an Audi A6 and I noticed that it has a night vision feature. How do I enable this feature and is it useful for night driving?

To enable night vision on your Audi A6, first make sure the headlights are turned on. Then, press the 'car' button on your control panel, followed by the 'night vision' button. This feature can be useful for night driving, as it uses thermal imaging to detect objects on the road that may not be visible to the naked eye.
