i thought dynamic hitch assist was just showing blue lines for backing up to your hitch that project where you're going to line up, similar to how our front camera works.
maybe that knob is the new gear selector like Dodges, and the hand lever is just a hand rest only LOL. j/k obviously, but I was really surprised when I saw dodges really do only have a KNOB to change gears. The center console shifter is already pansy enough, a KNOB? What is it a minivan?! lol
I'm digressing, it may be a terrain selector. Our explorer sport has a similar knob with settings for mud, snow, gravel, etc. With the auto 4wd feature, I wouldn't be surprised at all if the knob was for selecting different modes.
