Hi, I've noticed that my MS will turn on the HVAC (or continue to run the HVAC) even when the car is off. For example, I get to my destination and exit the car. Then start to unload - my son, bags, etc - and the HVAC continues to run. Similarly, it turns on as soon as I open the door in the morning and begin to load (son, bags, etc). It seems more natural for the HVAC to not turn on until the car is turned on. Part of my concern is that during these times (load/unload), doors are open and so running the HVAC is very inefficient. Is there any way to adjust this? (Other than manually turning off HVAC when I am about to exit the car?) Thanks!
