My '08 FX 45 came with a "Snow Mode" switch, unfortunately none of the sales personnel I spoke with on my purchase could give me a concise answer to what exactly this does. I can feel that when it is engaged that it automatically slows the wheel acceleration thereby decreasing slip, but when I asked if this put it in AWD all the time mode I received differing opinions. When I checked the Owners Manual it did not really say. Any one know?? Thanks.
