Well, as my car is post-september prod, I have the feature. I tried it yesterday morning: it was freezing -3°C, so all windows were frozen. I set the auto ventilation/heating to start, and checked it out about 30 minutes later.
The only thing the car did was blowing very cold air into the passenger's compartment. No heating whatsoever.
Although the manual clearly states "heating".
Anyone who knows if I'm doing something wrong ? It would be extremely cool (actually, "hot"
) if I could have my car defrosting all windows by the time I leave for work !
