Where do you jump start a 2007 BMW 750li?

To jump start a 2007 BMW 750Li, locate the battery in the trunk, as it's stored there. Open the trunk, remove the access panel, and connect the positive (red) jumper cable to the positive terminal and the negative (black) cable to a grounded metal point in the trunk. Then, connect the other ends of the cables to the donor vehicle's battery and start the donor car. Once the BMW starts, remove the cables in reverse order.
