To start a dead car, you generally need a set of jumper cables and another vehicle with a working battery. First, park the working car so the batteries are near each other. Then, connect the red cable to the positive terminal of the dead battery, and the other end to the positive terminal of the good battery. Connect one end of the black cable to the good battery's negative terminal, and the other to a metal part of the dead car's engine block. Start the working car for a few minutes, then try to start the dead car. If it starts, let it run to recharge the battery.
