How do you jump start a car with a Cadillac ats?

To jump-start a Cadillac ATS, 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) jumper cable to the negative terminal of the working battery and attach the other end to a grounded metal surface on the Cadillac ATS, away from the battery. Start the working vehicle, then attempt to start the ATS.
