How do you jump start a 1998 BMW 318i?

To jump start a 1998 BMW 318i, first ensure both vehicles are turned off. Connect the positive (+) terminal of the dead battery to the positive terminal of the working battery using a jumper cable. Then, connect the negative (-) terminal of the working battery to a metal ground on the dead car (not directly to the negative terminal). Start the working car, let it run for a few minutes, and then try to start the BMW.
