Probably already posted on this thread, but now that its cold in the middle of winter....this is a great function....

If you have automatic climate control, there is a button on your HVAC control that either states "REST" or "MAX".

If it is cold, usually below 50F, and you park your car and know you'll probably be back within 20 minutes, there is a "residual heater" function.

Turn off the car, press the "REST" or "MAX" button and there will be a green light on the button. The HVAC will blow the left over heat into the car for about 20 minutes and will shut itself off.

So if you run an errand (e.g. picking up clothes from the cleaners, going to the store, etc.), when you come back, the car will still be nice and warm.
