How do you jump start a 2007 cls 550?

To jump-start a 2007 CLS 550, you’ll need a set of jumper cables and a functioning vehicle. First, connect one end of the red cable to the positive (+) terminal of the dead battery, and the other end to the positive (+) terminal of the working battery. Next, connect one end of the black cable to the negative (-) terminal of the working battery and the other end to a metal ground on the car with the dead battery. Start the working vehicle, let it run for a few minutes, then attempt to start your CLS 550.
