Here are a few tips on how to safely jump start a Mercedes-Benz

Tip 1 – Use the dedicated jump start terminals

Most Mercedes-Benz models such as the E, C, S, CLK, ML, CLA, GL, G Class have a positive battery terminal in the engine bay designed specifically for jump starting. The terminal is cover with a red plastic cover marked with a (+).  This terminal should be used to jump start a Mercedes-Benz whenever possible. Right next to it there is a post for you to connect the negative clamp as well. This adds a layer of protection in case you incorrectly connect the jumper cables.

Tip 2 – Disconnect and charge the battery whenever possible

If your situation permits, it is better to disconnect the battery terminals and charge the battery separately before you try starting the Mercedes-Benz. By fully charging the battery before you try to start the car you will avoid triggering unnecessary warnings and fault codes. It is less likely to cause damage to electronics components as well. Warnings such as Low Battery Voltage, SRS Airbag Malfunction can be triggered when jump starting an MB since the battery takes a while to get charged. This can be avoided if you charge the battery before you start you car. If you have a completely discharged battery which is relatively new, we recommend charging it using 2 amp trickle charge to bring the battery back to life. We frequently use a Black and Decker 12 volt Trickle Charger to charge Mercedes-Benz battery. Keep in mind that you need to charge the battery for at least 12 hours using this method.

Step 1 – Connect the jumper cables or jump box to your dead Mercedes-Benz battery and let it charge the battery for at least 10 minutes before the jump start. Not only do you start the battery recovery / charging process but it will be easier to crank the engine. Otherwise, you may only hear a click and the engine won’t turn over.

Step 2 – Continue to keep the jumper cables connected for another 10 minutes after you start the car. The jump box will provide current for your Mercedes-Benz if the main battery voltage is still low. In the meantime, the main battery continues to get charged.
