Second Small Battery

For your information for those that don't know, I have been told by 2 MB technicians I have a second really small battery which will allow one to shift the electric-controlled transmission shift in the event the main battery is dead. I have heard nothing about this battery before. With the main battery dead (and I asssume the second battery having some charge left), you will hear a rather fast and loud pulsating beep when you open the door and you will see a lighted (I don't know the proper name) speedometer/tachometer/multifunction display. The second time Mercedes-Benz Roadside Assistance responded (my battery has gone dead 3 times so far) the technician did not have a charged portable battery pack so we had to shift the transmission to neutral so we could push the ML out of my garage and jump it with the R class he drove. If the small battery had been dead too, like the first time my main battery went dead, I don't know what they would do to shift the transmission to be able to move the car without a portable battery pack.

I have an appointment today to bring my ML to my dealer for service. I am going to leave it with them for a day or whatever it takes. And yes, I did take it to my dealer the first time the battery went dead and they couldn't find anything wrong.
