Remembering when I learned to drive (many) years ago when all cars were RWD the cars handle differently in snow. I've got 4 snows on the road and just keep my tank fairly full here in Western NY....never had a problem EXCEPT when I was on a scout campout trying to motor up an icy grade...car wouldn't go there on it's own but with 10 scouts pushing it I guess I wasn't really stuck.

I'd encourage you to get into the snow and play with the car to aquaint yourself with the feel. Something I do every year...and stay away from camping in the winter
