While the Mercedes-Benz ECO Start/Stop System cannot be permanently disabled, it can be turned off each time you start your car. Follow these three steps:
Locate the black button with a white capital “A” encircled by a clockwise arrow.
Depending on your model, this “A” will be in one of the following two locations:
Center Console – To left of the COMAND® button, in the bottom corner
Directly below the Start/Stop Engine button – Look for the “A” button right beneath the Start/Stop Engine button
Press the button to turn off ECO/Start Stop System.
