Wondering how to jump a car? Whether it’s because you’ve accidentally left the lights on or your battery is getting a little older and will eventually need to be replaced, it’s important to know the steps required to perform this simple procedure.

Jumping a Car

Step 1: Safely Position the Vehicles

You naturally want to make sure your car and the one you’re using to jump it are close enough for the jumper cables to reach. While you’re doing this, make sure the two vehicles are not touching. Additionally, shut them both off, apply the parking brakes to keep them from moving, and see to it that no one is standing in between them while the charging is taking place.

Step 2: Conduct a Quick Inspection of the Cables and Batteries

Once the cars are situated the way you want them, pull out the jumper cables to see that they are in proper working order. You’ll also want to examine the batteries themselves. Both need to be clean and free of leaks and cracks.

Step 3: Attach Positive to Positive

To attach the cables to the batteries, the first thing you’ll want to do is locate the positive cables and the positive battery terminals. Both should be marked with the color red. Connect the positive cable clamp to the positive terminal on the dead battery first. Then do the same with the good one. 

Step 4: Connect the Negative Cables

The color that designates which cables and terminals are the negative ones is black. Next, match the negative clamp with the negative terminal on the working battery. Attach the remaining negative clamp to an unpainted metal surface on the disabled vehicle. Be careful to make sure that no part of it is touching the battery.

Step 5: Jump-Start Your Car

Start the car with the good battery and let it run for two to five minutes. Once you get your car going, let it run for a few minutes to see if the charge keeps.

Step 6: Remove the Cables Safely

Take all cables off in the opposite order that they were attached. While you’re doing this, avoid sparking by not allowing them to touch each other.

Don’t forget to consult your owner’s manual to brush up on each step of this procedure.
