What's This Thing ?
I slightly removed the carpet and to see what was behind the carpet
I came across this tool near by the spare tyre . So, what's it ? I looked the manual and could not figure out what it was lol
There are cables but it's not battery
Another thing, my tires are Continental but this spare tyre is Pirelli
. So, I would appreciate some of guys take a look your spare tires and see if these are also different brand or not
BTW, I am very happy with my Continentals
Thanks

Battery ? WOW, I thought it was battery too but I know our battery is located in the front not in the trunk so this is why I ruled out that option lol
Thanks for your replies, it never dawned on me that there was a battery for ECO / START thingy lol

Spare tires are spare tires. They don't have to be the same brand or size. My car came with continentals and have Pirelli spare too, also in full size. I don't know about the US spec, but in china, all the imported W212 came with full size spares. The made in china stretched version E (V212) now come with midget spare.

lol Well, thanks for your reply , I will e-mail this image to a friend of mine in the dealership . Let's see what it turns out to be lolEDIT :
Final verdict is it's an additional battery that helps ECO / START system run on . Let's say you turn on this ECO button and waiting at the lights and this ensures engine to stop and start when you press the gas pedal it helps the engine start w/o making it feel any jerk

Can this secondary battery be "tapped" like the primary battery for an auxillary amplifier, etc.? It would be great to not have to run a power cable from the main battery up front.

If you have a full size spare and it is not the same as the driving tires on the car, I would ask mercedes to replace it with the same tire as your driving tires....someone, at some point, will use that tire to retire a wheel and you will have a mismatch of tires.
