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 damaged starter motor
A faulty ignition switch or fuse
A severely drained or expired battery
