I got into the XF very early yesterday morning and the outside air temperature was very cold. The windscreens were misted up a bit. After I started the engine I thought that I would need to demist the front and rear screens. As I looked down at the front and rear windscreen heater controls, I noticed that the XF had already switched them on for me! The climate control really is very, very good as it focused on clearing the windscreen first...all by itself.
