For snow driving most cars if you put it in "2" you lock out
low gear & make it much easier to get traction & avoid
downshifts going up hill.
On RWD it also eases you down hill with very little braking.
Just avoid sudden downshifts or you get spin out.
With FWD there are a few more rules. Biggest thing with FWD
is if you HAVE to go out in snow storms get snow tires. You
may not need them but it makes a HUGE difference.
My 1st FWD car was one of these.

About 3000 lbs sitting over the front wheels made it go in snow even
with bald bias ply tires. Added snows the next year & you could
go almost anywhere a big 4WD truck can.
