Cabin, coolant, engine oil, transmission oil and fuel temperatures are eletronically managed and include back up heaters to bring them to ( and keep at) operating or set up temps.

Actually from my experience over the Christmas break this is not true for the cabin controls and the temp was only -28 to -31Celsius.
I did my winter loop to visit family and over our 10 day winter break. On the first leg of trip the battery was frozen to the point where the car would start but not provide heat under the Auto or manual function. The voltage is too low, and the computer will not allow the fan to run in auto or manual.
The only way to keep the windows from frosting was to push the defrost setting which works fine to keep the front windshield from frosting up but you get no heat on your midsection or feet. Driving like this for many hours is not fun.
Needless to say there are additional items required to make this vehicle work in winter. -31 celsius was enough to freeze the battery to keep the fan function from working and it never really worked until the last portion of the loop where we lucked out and a Chinook system was able to warm the battery up to around -10 celsius.
Talking with the SA, this happens to be a common issue to when the temp drops.
