Whenever you jump start any car, the cables should be connected positive cable first, then wait at least 30 seconds. Waiting for a short period of time will allow the car with the weak battery to adjust to the newfound power. Mercedes was smart enough to realize that even their batteries can go dead & installed a voltage control device called overvoltage relay to protect the computers!!
