How do you jump-start a Mercedes C200?

To jump-start a Mercedes C200, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the positive terminal of the dead battery, then attach the other end to the positive terminal of the working battery. Next, connect the negative (black) cable to the negative terminal of the working battery, and then attach the other end to a grounded metal surface on the car with the dead battery. Start the working vehicle, allow it to run for a few minutes, then attempt to start the C200.
