You cannot turn it off, or better yet why would I? Maybe to zip around a parking lot like a kid spewing snow in donuts?
Think I found the reason the Durango was sliding all over yesterday. Remembered it has a SNOW MODE. Only tried it for one or two swings, but I believe that is the ticket to get the stability control to work as expected in the slick. When in that mode it says T/C = FULL, in street T/C = STREET.
Find some snow and try it.
I switched and did my driveway corner like the afternoon, indeed it felt different and very similar to the Jeep in its Street mode. Going to take it back to Iowa and back in the next couple of days. I’ll confirm soon.

Seems like here and south to there at least all have at least 6-10” that made the place ready for Christmas.
We do not generally use that at all in the Jeep, because besides changing the AWD percentage front/rear it raises it up a couple of inches. In the worst shit, I have never needed to change any setting in that wonderful machine.
I say absent slick conditions/spots and on these cold roads and air, that 392 combo with the new tires? Bad ass to the max if others are in the way.
