Keeping jump leads in your car can be the difference between being stranded on the side of the road and doing a quick repair to go about your day. Jumping your Mercedes-Benz E350 is the same as jumping any other vehicle; you must find the correct battery terminals on your car as well as a car with a working battery. The car with the working battery will give your Mercedes' battery a charge, allowing it to have enough power to operate once again.
Park a car with a live battery beside the Mercedes E350 and pop both bonnets, so you have easy access to the batteries.
Attach the positive jump lead clip to the positive battery terminal on the Mercedes E350. The cable is red on most jump leads, and most batteries have a "+" sign to indicate positive.
Attach the other positive jump lead clip to the positive terminal on the other car.
Attach the negative jump lead clip to the negative battery terminal on the vehicle with the working battery. The cable is black on most jump leads, and most batteries have a "-" sign to indicate negative.
Attach the other negative jump lead clip to a piece of metal under the hood of the Mercedes to ground the current.
Start the vehicle with the working battery. Allow it to sit and run for a few minutes, which will charge the Mercedes' battery.
Unclip all jump leads in reverse order.
Allow the Mercedes to run for several minutes before turning it off.
