How do you jump start your BMW x5?

To jump start your BMW X5, first ensure both vehicles are turned off. Connect the red positive cable to the positive terminal of the dead battery and then to the positive terminal of the working battery. Next, connect the black negative cable to the negative terminal of the working battery and attach the other end to an unpainted metal surface on the dead vehicle to ground it. Start the working vehicle, let it run for a few minutes, and then attempt to start your X5.
