I have noticed that one can activate both the seat heaters and ventilation at the same time. I have never seen that before in any of my other cars. Interesting "feature" as it allows the seat heater to work but draws away any sweat/moisture

I have never tried this, I will have to give it a shot tomorrow on my way to Cars and Coffee.

Our RS6 does the same, seat heaters and vents can be activated simultaneously.

it’s for when you’re wet from rain. Mercedes has done this for 30 years.

I can activate both on most cars. One is an electric grid for heat and the other is just fans so it doesn’t really matter if both are on or not in regards to causing a problem.

I do it sometimes when I get in the car in wet ski pants. Works geat in the cayenne - dry and warm.
