Snow and Ice Mode !
This setting, minimum for doing similar to off-road assist 4 wheel drive all the time.
- chill acceleration
- reduce regen
I have been using off-road assist on the snowiest / slippery days in Tahoe this winter.. it makes a big difference, especially on side roads / steep slippery driveways.
- I have the regen low setting, although I've never noticed a slipping related to regen like breaks locking up (on previous cars).
- chill mode same thing, makes sense, but good tires (vredstein quatrac pros for our kind of driving / location) and off-road assist make the biggest differences.
I haven't noticed or needed the traction control, but could see it being good with awd all the time.
