How to Jumpstart Your Car

  1. Park the working vehicle next to the car that needs a jump. Don’t let the vehicles touch, or it could cause a short.
  2. Put both cars in park and turn off their ignitions.
  3. In both cars, turn off lights, the radio, air conditioning, things plugged into power outlets, and anything else that can drain power from the battery.
  4. Before going any further, take a look at both batteries. If either battery is cracked or leaking, do not attach jumper cables. The battery could explode.
  5. Locate the dead battery’s positive and negative terminals. Luckily batteries are usually clearly labeled with + and – signs, so they should be easy to find!
  6. Connect the jumper cables. Attach one red clamp to the dead battery’s positive terminal, and the other red clamp to the working battery’s positive post. Connect the black clamp to the working battery’s negative post, and the other black clamp to any solid, unpainted metal surface inside the dead vehicle’s engine compartment, like a nut on the engine block. Don’t worry if you see a spark after connecting the negative cable. It’s totally normal.
  7. Make sure the cables are secure and not touching any moving engine parts.
  8. Start the working car. Let it idle for a few minutes to feed power into the dead vehicle’s battery.
  9. Check that you have the cables set up correctly by turning on the dome light in the dead vehicle. If it turns on, they’re good!
  10. After a few minutes, start the dead vehicle and let them idle together. If the engine is cranking but won’t turn over completely, give it a few more minutes and rev the engine of the working vehicle.
  11. Once the dead car is running smoothly, it’s time to remove the jumper cables. Be careful not to let the clamps touch each other, or you could be in for a serious shock. Disconnect the jumper cables in the reverse order you connected them: black clamps first, then red.
  12. You’re good to go! Allow the dead vehicle to run for at least 30 minutes. This gives the battery time to recharge. Make sure you drive the vehicle somewhere safe before shutting it off in case you have to jump your battery again.

Remember to always keep a set of jumper cables in your car emergency kit to help you and other drivers!
