On mine, I wasn't facing uphill, I used the hard button, and it creeped toward the hill and then started its ascent, by itself... And I was pretty sure the box in uconnect is still "start" assist which is different. That's when you park facing uphill on a steep hill like in some towns, "San Francisco, Ca, Portland, Me, Etc".
Normally what can happen in THAT situation, is if your foot is not on the break you can roll backwards, and sometimes put the transmission in a bind. That hill start assist, helps by applying the brakes for you to limit the roll back and not put the transmission in a bind to allow a seamless travel up the hill.....
Of course I could be wrong, but that is what I read in the book?? LOL
