Good question that I don't have a direct answer. If'n you have a refresh I can't see it will harm anything, trying the procedure.
Auto parking brake?

It wouldn't surprise me the least that gm took that away also, on the global b, only thing better that I have come across is a bigger screen, that you can't do much with, and animated lights.

2022 1500, the only time the parking brake auto engages is when I back up to a trailer using the hitch camera. Never had it auto engage otherwise.

Interesting, mine engages anytime I’m on less then flat ground and whenever I have tow/haul mode engaged while pulling a trailer.
