To start a Mercedes with a dead battery, one option is to jumpstart it by connecting the running car’s battery to the dead one and waiting a while before starting. The “donor” car must rev slightly up for the alternator to provide enough power.

Another option is to manually start the Mercedes by inserting the SmartKey® into the ignition, pressing the brake pedal, ensuring the transmission is in Park, and turning the key. Symptoms of a dead Mercedes battery include the dashboard lights not coming on, accessories not turning on, and the car not starting when the ignition is turned on.

Possible reasons for a Mercedes not starting include a depleted battery, issues with the gear selector or brake light switch, faulty sensors or ignition system, and problems with fuses and relays.
