At Mercedes-Benz of Arrowhead in Peoria, AZ, we’ve compiled a step-by-step guide to jump-start your luxury vehicle.
What You Need to Jump-Start Your Car

- A set of jumper cables
- A second vehicle with a working battery
- Electricity-safe gloves
- A blanket (optional for added safety)
Step-by-Step Guide to Jump-Starting Your Mercedes-Benz
Position the Vehicles
- Park the assisting vehicle close to your Mercedes-Benz, ideally with the hoods facing each other. Ensure both vehicles are in Park and the parking brakes are engaged.
- Turn off the engine of the assisting vehicle.
Locate the Battery Terminals
- Open the hoods and identify the battery terminals on both vehicles.
- Positive terminals are usually marked with a red cover, while negative terminals are black.
- Check for corrosion—clean off any buildup before proceeding.
Attach the Jumper Cables in the Correct Order
- Connect the red clamp to the positive (+) terminal of the dead battery.
- Connect the other red clamp to the positive (+) terminal of the working battery.
- Attach one black clamp to the negative (-) terminal of the working battery.
- Finally, to ground the circuit, attach the remaining black clamp to an unpainted metal surface on your Mercedes-Benz (not directly to the battery).
Jump-Start the Vehicle
- Start the engine of the working vehicle and let it run for a few minutes.
- Try starting your Mercedes-Benz. If it doesn’t start immediately, wait a few more minutes and try again.
Safely Disconnect the Cables
- Once your Mercedes-Benz starts, carefully remove the jumper cables in the reverse order:
- First, remove the black clamp from the grounded metal surface.
- Then, remove the black clamp from the working battery.
- Next, remove the red clamp from the working battery.
- Finally, remove the red clamp from your Mercedes-Benz battery.
Allow the Battery to Recharge
- Let your vehicle run for at least 10 minutes to allow the alternator to recharge the battery.
- Take a short drive to ensure the battery holds a charge.
When to Seek Professional Assistance
If your Mercedes-Benz doesn’t start even after attempting a jump-start, there may be an underlying issue, such as:
- A failing alternator

- A faulty ignition switch or fuse
- A severely drained or expired battery
