How do you jump start Mercedes s320?

To jump-start a Mercedes S320, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery and then to the positive terminal of the working battery. Next, connect the negative (black) jumper cable to the negative terminal of the working battery and attach the other end to a metal ground point on the dead vehicle, such as an unpainted bolt or bracket. Start the working vehicle, let it run for a few minutes, then attempt to start the S320.
