Ozzieg, Have you checked your battery ground cable? Take a test light from your positive battery terminal cable and try to ground it out on the engine or on the body of your ML and see if you have a good connection.
I don't know of a ""Reset Button"

There is no reset button. Check the cables as suggested and have the battery charged. If it depletes itself again over a short period of time have the battery checked out for being defective, if not defective have the car checked out for a current draw when shut off.
