when placing the black jumper cable on the dead car, put the clamp

Clamp the black jumper cable to a solid, unpainted metal part of the dead car’s engine block or chassis, away from the battery and fuel system, not to the dead battery’s negative terminal.

Correct placement of the black clamp

When jump-starting a car, the usual safe recommendation is:

1. Red clamp to the positive (+) terminal on the dead battery.

2. Red clamp to the positive (+) terminal on the good battery.

3. Black clamp to the negative (−) terminal on the good battery.

4. Black clamp on the dead car to an unpainted metal part of the engine or chassis, away from the battery (a bolt, bracket, or engine lifting point is typical).

That last step is what your question is about: the black clamp goes on a grounded metal part of the dead car, not on the battery terminal.

Why not on the dead negative terminal?

Placing the final black clamp on bare metal away from the battery helps:

• Reduce the chance of sparks right above the battery, where hydrogen gas might be present.

• Provide a good ground connection through the car’s chassis/engine.

Many guides summarize it as: red to dead, red to donor, black to donor, black to metal.

Mini forum-style takeaway

When placing the black jumper cable on the dead car, put the clamp on clean, unpainted metal on the engine block or chassis, away from the battery and moving parts.
