How do you jump start an E220?

To jump-start a Mercedes E220, first ensure both vehicles are turned off. Connect the 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 black jumper cable to the negative terminal of the working battery and attach the other end to a metal ground on the E220, away from the battery. Start the working vehicle, let it run for a few minutes, then attempt to start the E220.
