Much has been written about whether or not to Jump Start a R129 dead battery. The owners manual says to follow the
M-B procedure Remember to have the Ignition Key in position 0 , and connect the Negative (-) terminal last before attempting to start the car.
Many M-B mechanics will tell you that they have done a lot of work on cars that have been jump started incorrectly and this has ended up costing the owner big bucks for the replacement of such electrical components as the ECU, etc., please see

Note: The battery is located on the right side of your trunk and there are Service Mechanics that have suggested that you put a piece of Duct Tape on your battery with a label that says, "
Do not Jump Start or Charge this battery without first contacting the owner." or utilize a
12 Volt Antizap Surge Protector
IMO, if you are in the U.S. why not utilize the
"free" M-B Roadside Assistance
