In cold weather starting out at 244 miles, I drive 6 miles with the heat on at 26F and the mileage drops to 200 miles. A few miles later with the battery heat "on" the mileage goes back up to 222 miles. Sooooo many Gothcha's with this vehicle. It does not like cold weather. The computer dash is horrible, Radio [cd] delete? GPS is lost. Trunk space = none.
