I always want the car to power off automatically if I exit the car with the fob (even if I don't lock the car with the fob after leaving it, since it does not do this automatically I think, is there an option for this?). So I must keep the 'Auto Power ON/OFF' feature enabled (Page 198 of manual). I am also assuming that there is a time gap here, that although the car powers off it doesn't just shut everything off the moment the fob is a little out of the car, that it will stay powered on until I walk sufficiently far away from the car for a long enough period, which I haven't tested but the specifics are probably not configurable, fine.
But I never want the car to power on automatically when I enter the car with the fob, where the car was auto-powered off by the fob leaving the car when I last left it and then locked with the fob button. I always want to use the Start/stop button to start the car. Page 198 of the manual states that if I turn the car off with the Start/stop button before leaving it, then this will accomplish that, but then obviously there is no auto-power off since I'm offing it manually instead.
So is there a way to always use the Start/stop button to turn the car on (Manual Power ON), but to allow the Auto Power OFF function only?
Also is there a button combination to disable the fob itself / put it into energy saver so it can't be relayed and doesn't need to be put in a shielded pouch (not that anyone would get very far jacking an E, I doubt a single one has been stolen

Thanks all.
Edited, separately does anyone know what the 'outer handle pop-out setting' does, I thought this would disable the pop-out when the car was unlocked or door opened, but it doesn't do that. Manual says it's supposed to "activate the custom settings on key fob for the outer handle auto pop-out function", what does this mean?
