Well we all live and learn..
Friends calling each other idiots are not really friends are they ??
I guess the buttons in a 4x4 are always a bit confusing at the start, since they are easy to play with, and we, as humans always tend to think that if we get stuck, the buttons will always make the car come clear again.
Point is, as explained above, when on slippery ground, keep the torque on the wheels down to a minimum, and try to ease out. Wheel spin will only make things worse, unless you're on thin ice/black ice/snow, and are wearing your spiky tires.. but then again.. if you're fitted, then you wouldnt be stuck in the first place :-P
Always remember, in your old fwd manual car, you would put the car in 3 or 4th gear and slowly ease out of trouble.. Same goes for the 4x4. Just because all 4 wheels can spin, doesnt mean you dont need to use the conventional thinking :-P
Anyone watching the TopGear Polar special would know this :-P
I would recommend watching this episode to maybe learn a little bit more about snow driving, and especially getting out of a snow bog.
