I don't have my manual in front of me so I haven't checked this out yet, but it seems like the Auto start stop function triggers with a firm press of the break pedal once you are stopped. I've found that I can prevent it from engaging by using just enough pedal pressure to keep me from moving and if I want to engage it, I just press a bit harder. The only time this hasn't "worked" is when I'm on an upward incline - when I try it then, the indicator light on the dash board lights up amber and nothing happens. Like I said, I need to check the manual out, but this seems like an interesting feature. I know I can turn it off completely by pressing the center console button to disable it for that trip, but having control via the brake pedal seems handy. I've found this useful when waiting at a left turn on green situation where I'll need to go quickly and don't want any hesitation. Has anyone else seen this behavior?
