Park the functioning car so that the vehicles face each other, preferably only about 18 inches apart, but never touching each other. For automatic transmission cars, put the vehicle in park; for a manual transmission, set the vehicle to neutral

Set the parking brakes on both, so neither car moves unexpectedly

Both cars should be turned off, with keys removed

Set down the jumper cables on the ground, making sure the clamps do not touch each other

Open the hood to both cars, and locate the batteries (refer to the owner’s manual for battery location) and battery terminals. Usually, the two terminals on each battery will be covered in red or black, with a + or – sign on top. Look at the batteries and make sure that you can identify which is positive, and which is negative. This distinction is crucial to the success of your jump. If the battery terminals are dirty, wipe them off with a rag or wire brush.

Attach the red, positive cable clamp to the positive (+) battery terminal of the dead battery. You want a solid connection to the battery terminal, which may require some initial wiggling of the clamps

Attach the red, positive cable clamp on the other side of the jumper cables to the functioning vehicle’s positive (+) battery terminal
Connect the black, negative cable clamp to the working battery’s negative (-) battery terminal. Walk over to the car with the dead battery. Do not connect the black, negative cable clamp to the dead battery. Instead, attach that clamp to an unpainted, metal part of the car such as a shiny, clean nut on the engine block. This will help ensure a safe jump.


Start the working vehicle

Wait a minute or so. Depending on the age of the battery and how long since it died, you may need to let the car run for a minute or two to get the jump to work.

Try starting the dead car. If the car doesn't start, allow the working vehicle to charge the battery for an additional minute or two before attempting again. In some instances, slightly revving the engine of the working car while charging the dead battery may help.

Once the dead car is running, you may disconnect the jumper cables, starting with the black, negative cable clamps. Do not let the clamps touch each other while any part of the cables is still attached to a car.

Now, take a short drive. This will allow the battery to build up a charge. This driving allows the vehicle’s alternator to charge the battery and ensures that your vehicle does not die again once you turn it off.
