I have the 1.4 auto petrol stop/start and it says so long as requirement are met, on of which is engine temperature but can't remember what else they said, it turns off when you apply the footbrake. This happens when the shift is in drive, not tried it when using the manual function as I don't use much. I got this feature because it came with the car, it wasn't something I would have asked for but it has surprised me how well it works. As soon as you lift foot of the brake pedal engine has started.
Don't know if its a gimmick or actually does good but it certainly works exactly as they said it would
