Two things: A "sprinkler hose" one of those flattish multi tube hoses with small holes all over the top of the hose placed in long coils under the car makes a great belly wash. Also, a trucker I used to drive with taught me that you should go into Neutral if you have any idea that you may slide in a stopping situation. Works well on the XF so far. No sideways funhouse stuff on these icy TN. hills (yet).
Thanks folks, for all the other help. This is a GREAT forum! 
I disagree with the Nuetral thought. When you put the car in N you lose one of your controls. You shouldn't really use the brakes on the ice anyway. They don't do anything but stop your front wheels from spinning and put you into a slide. Sort of the same concept as hydroplaning.
