Connect jumper cables in the right order

The order isn't superstition: the last clamp sparks, so it goes away from the battery and its gas.

⏱ 45s

1. Red clamp to the dead battery's + terminal.
2. Other red clamp to the good battery's + terminal.
3. Black clamp to the good battery's − terminal.
4. Last black clamp to bare metal on the dead car's engine or frame, away from the battery.
5. Once the car is running, take the cables off in reverse order.

Tip: Procedures vary by car, so check the owner's manual first.
