I don't like the auto stop start, it seems like a gimmick to boost the EPA fuel economy numbers, I added a switch to disable it without having to hit the button every time I get in. I find it annoying and unpredictable, the manual states it should shut off anytime you stop except when the AC is on, but it fails to shut down under many other conditions (which I haven't been able to fully identify), when it does shut down, I don't really like it, I made it so it can be enabled in the drive through line. I've never noticed the hill holder, so I guess its on. Off topic, but I also don't really like the way the adaptive cruise control works, it slows down too far from the car in front, even on the farthest setting, and accelerates faster than I would like, so I frequently have that disabled. I also have the LKAS disabled, I don't really like it, I use for long trips occasionally. I also have the ADAS disabled, I find it annoying.
