The book says auxillery heating. It's a great gadget that will heat your car without the engine running. Let's say you want to use your car at 7 am, but do not have a garage. you set the timer and the preferred interior temperature. Your car measures the outside temperature all night then calculates how long it will need to heat to your preferred interior teperature. Kicks in by itself. The advantage is huge if your office doesn't have protected parking or you don't have a garage.
