The first option is available when ignition is off and car in accessory mode, ie when you first shut off the car and about to make a quickie stop at Starbucks. This is similar to the REST mode on older BMW and Benz, but the difference is that this one is buried under menus and can only be triggered within the first few minutes after stop.
The second and third options are timers that can be set anytime but will only run when everything is powered off. You do need to set this up after each run. The timers won't rerun itself on a daily basis
