My X type sailed thru today passing 90% of other stranded cars. I had to take staff home as their Audi/Mercedes/Porsche were stuck with wheel spins in car park :)
Only thing mobile around here was .. me .. and a Smart Car belting about. They are really good in the snow, Smart Cars!
Auto boxes lower gear selector is just a gear 'hold'. It will stay in that gear.
Steer into skids as in most situations. Try not to hit brakes in panic!
There are 2 steep hills which caught most cars, I weaved thru them on 2 (gear to side of D). I've never used those gears & dont know when they should be used.
My 1984 Golf is fine in the snow. It's all the newer cars that seem to have the trouble. Perhaps it's the tyres. Mine uses 155x13" which have a high profile and appear very 'upright'. Most modern cars seem to have much wider and lower profile tyres which can't be too clever in the snow.
Let's face it, there is a whole generation with no experience of driving on snow and ice and they get stuck because they 'gun' the car leading to spinning wheels instead of changing down to a lower gear (2nd is best ) and proceeding slowly. Agree with Albags on gears and skids. Also, as I mentioned in another post, keep a bag of kitty litter in the boot to put under wheels as traction.
I have an old VW Polo (89), it's great in the snow as it's front wheel drive. For those of you with rear wheel drive cars, stick the other half in the back to put some weight on rear axle.
