The steps for connecting jumper cables to a car: 1. Clamp the red cable of the jumper wire to the red positive terminal of the "rescued car" battery, then clamp the other end of the red cable to the red positive terminal of the "rescue car" battery. 2. Clamp the black cable to the negative terminal of the "rescued car" battery, then clamp the other end of the black cable to the black negative terminal of the "rescue car" battery. 3. Start the engine of the "rescue car" first, then start the engine of the "rescued car". Below are some precautions: It is recommended to use copper jumper cables with an outer diameter of 10mm or more; jumper cables that are too long can easily lose power, making it difficult to start the vehicle. Generally, it is recommended to use jumper cables that are 3-4 meters long. Also, avoid using jumper cables that cost only a few dollars, as their quality is very unreliable. They not only easily leak electricity but may also damage the car.
