How to jump-start a Mercedes-Benz in Manchester, NH
Open the hood, clip the red cable to the positive jump terminal under the plastic cover, and clip the black cable to unpainted metal on the engine block or frame. Start the donor car, give it two to five minutes, then try your Mercedes-Benz.
Most Mercedes-Benz cars have a dedicated jump terminal under the hood, so the cables never need to reach the battery itself. The battery is often in the trunk or under a rear seat, depending on the model.

Jump-start your Mercedes-Benz in Manchester, NH from the under-hood terminals
Mercedes-Benz typically provides a remote jump-start terminal under the hood, and that is the point you connect to. The terminal under the cover is positive, and the negative connection goes to bare metal nearby, so the battery stays out of the job.
What do you need before you jump-start a Mercedes-Benz?
You need a working donor vehicle and jumper cables with red (positive) and black (negative) clamps. Park the donor car close enough that the cables reach without stretching.
Winter makes this more than a theoretical need in Manchester. Manchester Airport averages 129.1 days a year with a low at or below 32 degrees Fahrenheit (NOAA, 1991 to 2020 normals), so a cold morning is a common setting for a dead battery.
Where are the jump terminals on a Mercedes-Benz?
Look under the hood for a plastic cover marked with a plus sign or a battery icon. The positive terminal post sits under that cover.
For the negative connection, look for a bare metal bolt or ground post nearby on the chassis. That is the point the last black clamp goes, not the dead battery.
In what order do you connect jumper cables to a Mercedes-Benz?
Connect the two red clamps first, then the two black clamps. Attach the cables in this order:
1. Clip one red clamp to the positive jump post on the Mercedes-Benz, under the plastic cover.
2. Clip the other red clamp to the positive (+) terminal on the donor battery.
3. Clip one black clamp to the negative (-) terminal on the donor battery.
4. Clip the last black clamp to an unpainted, solid metal grounding point on the Mercedes-Benz engine block or frame, away from the battery or fuel lines.
How do you start a jumped Mercedes-Benz and remove the cables?
Start the donor vehicle and let it run for 2 to 5 minutes. That feeds a charge into the Mercedes-Benz system. Then try starting your Mercedes-Benz.
Once it runs, take the cables off in reverse order:
1. Remove the black clamp from the Mercedes-Benz ground point.
2. Remove the black clamp from the donor battery.
3. Remove the red clamp from the donor battery.
4. Remove the red clamp from the Mercedes-Benz jump post.

FAQ
Why shouldn’t the last black clamp go on a dead battery’s negative post?
The negative post on a dead battery can be hidden or prone to sparking. Use an unpainted, solid metal ground point on the engine block or frame instead, away from the battery and fuel lines.
What should you tell roadside assistance when you call for a Mercedes-Benz?
Give the model and year of your Mercedes-Benz. Say where it is parked, such as at home or in a specific parking lot.
