This is what I was referring to when I say "Traction Control (DTC)". I know you recommended leave it on, but I'm still wondering if it makes sense to leave DTC on when going down steep snowy/dirt/gravel/muddy road where you might need more stability control than traction as it's downhill, unless it helps with braking traction which probably isn' the case. I was turning DTC on only for uphill in the snow and switching back to normal, DSC mode, when going downhill or faster on flatter sections. I really didn't like having to switch modes though and would prefer to leave DTC in snow and/or dirt even at higher speeds.
