Be Prepared!



Before you jumpstart your own battery, you can practice online with our interactive exercise. Just follow the instructions below, and print a copy to keep in your car or trunk.

Pull the car with the good battery next to the vehicle with the dead battery, or in a place where the cables will easily reach from the battery of one car to the battery of the other. The cars should not be touching and both ignitions should be shut off Prop open the hood of each vehicle. 

Visibly locate the batteries and their terminals. Each battery has two metal terminals. One is marked Positive (+); the other Negative (-). There are also positive and negative cables in the jumper set. The red one is positive (+), the black one is negative (-).

You will also need to establish a metal ground within the vehicle with the dead battery.
