How do you jump start a 1998 jaguar vanden plas?

To jump-start a 1998 Jaguar Vanden Plas, first ensure both vehicles are turned off. Connect the positive (red) jumper cable to the dead battery's positive terminal, then attach the other end to the positive terminal of the working battery. Next, connect the negative (black) jumper cable to the working battery's negative terminal, and attach the other end to a metal ground on the Jaguar, away from the battery. Start the working vehicle, let it run for a few minutes, then attempt to start the Jaguar.
