Anybody know exactly how it does that. Does it allow limited wheel slip? If so is it a percentage of front wheel rpm? Does it prevent one side from slipping if the other side is grabbing--maybe by applying brake to the slipping side?
In other words, just exactly what does it do and how does it know to do it?

That sounds more like a description of ASR rather than the snow chain mode. The snow chain button is just a way of partially deactivating ASR. ASR is so vigilant about avoiding wheel spin that sometimes with snow chains in heavy snow it prohibits the car from moving at all. Depressing the snow chain button allows for a little more wheel spin.
