How do I enable Audi's night vision in my car?

I recently purchased an Audi A6 and have been very impressed with the technology. However, I can't seem to figure out how to activate the night vision feature. Can anyone provide some guidance on how to enable this feature?

To enable night vision in your Audi, first make sure that your car has the optional night vision assistant feature. If it does, simply navigate to the settings menu on your infotainment system and select 'Night Vision'. From there, you can toggle the feature on and off.
