Locking Vehice While On
I have otherBenz's and I simply lock the door with the manual key, the ML is not allowing this?

P.S.
Thats why they have a heated seat option.
But in your case you are driving it to the 7-11 and want to continue to heat the car while you run in.. AHH the ML has a special button for this look at your 3 a/c controllers and the middle one you will notice it says AC REST turn off your car then hit the AC REST button and turn up the fan speed to desired it limits at like 2 1/2 or 3 and turn it to heat (recommend using full fan speed and full heat temp). It will take residual heat from the motor and heat the car for up to 30 mins or so then auto turn off, or if the voltage on the battery drops it will shut off.
