How do I enable Audi A8 interior ventilation?

I recently purchased a new Audi A8, but I am having trouble figuring out how to enable the interior ventilation system. Can anyone provide some guidance?

To enable the ventilation system in your Audi A8, simply press the "Vent" button located on the climate control panel. This will allow fresh air to flow throughout the vehicle's interior.

One helpful tip for increasing the effectiveness of your Audi A8's ventilation system is to regularly replace the cabin air filter. This will ensure that clean air is circulating throughout the car at all times.
