My only time I have driven a VX in snow I used 4-Lo the whole time. Totally stock with not-so-great street tires on some old logging roads that hadn't been plowed and hadn't had to much traffic on them, so just 2 grooves cut out. Got stuck going up a hill in normal TOD mode so that when I put it into 4-Lo and just left it. Tried winter mode for a bit but that was way worse than normal. Maybe good for light snow on pavement, but useless off-road in snow.
