I had my dealer coded the new settings for the Start/Stop button. Now, it will use the previous settings which I prefer.
On the side note. How much savings does it really have? I am sure that those frequent Start and Stop will be taxing for the Starter and the Battery. So the probability of earlier failure of the starter plus the depletion of the battery, not to mention the alternator, will surely increase. You can contend that it is more greener doing so but having more parts to replace will make it less green.
