Where is the negative terminal for jump-starting an Audi A6L?

The jump-starting position for an Audi A6L is located on the left side of the engine. Ensure that the discharged battery and the rescue battery have the same voltage. Car batteries are typically 12 volts. Trucks or tractors may operate on a 24-volt system, sometimes combining two 12-volt batteries to form a 24-volt system. Never connect a 12-volt battery to a 24-volt battery. Steps for jump-starting a car: Take out one cable; first connect one end of the cable to the positive terminal of the rescue car's battery, then connect the other end to the positive terminal of the discharged car's battery. Take out another cable; first connect one end to the negative terminal of the rescue car's battery, then connect the other end to a metal part of the discharged car's engine. Start the rescue car; then start the discharged car following the normal procedure. Quality of jumper cables: When purchasing jumper cables, choose genuine, quality-assured cables. Opt for thicker ones with an outer diameter of at least 10mm and a length of around 3 meters. Avoid cheap, low-quality cables priced at just a few dozen dollars to prevent them from burning out due to inability to handle large starting currents.
A few days ago I just helped a friend jump-start an Audi A6L. The negative terminal position is usually a sturdy grounded metal point in the engine compartment, such as a bolt on the engine block or a metal part of the frame. Never connect directly to the negative battery terminal—that's extremely dangerous because hydrogen gas in the battery can cause an explosion if sparked. Specifically, the grounding point for the A6L is often on a small black bracket near the radiator under the hood, which is easy to locate—just clamp it securely. When jump-starting, remember the steps: first connect the red clamp to the dead battery's positive terminal, then attach the black clamp to this grounding point, and only then connect to the rescue car's battery. Ensure the vehicle is turned off, connections are firm, and wires aren't crossed to prevent short circuits. Always check the battery condition—if anything seems off, seek professional help immediately rather than pushing through. While jump-starting is simple, safety comes first. Regular battery maintenance habits can prevent a lot of trouble.
