Step 1: Make sure the car you are about to get a jump from is close enough for the booster (also known as jumper) cables to safely reach both batteries without the cars touching each other.

Step 2: Turn off all accessories on both cars. This means headlights, radios, flashers, or any other items running from the battery.

Step 3: Set the emergency brakes in both cars.

Step 4: If possible, place a damp cloth over each battery.

Step 5: Place one red clamp of the booster cables on the positive post of the dead battery. Remember this post will be marked "plus" (+) for positive.

Step 6: Place the the red clamp on other end of the cable on the "plus" (+) post of the good battery.

Step 7: Connect one of the black clamps of the booster cables on the "negative" (-) post of the good battery.

Step 8: Connect the remaining black clamp to the engine or some metallic surface of the stalled car. This is the "ground." It is important that the clamp be as far away from the battery as possible and none of the cables are in the way of any moving engine parts.

Step 9: Start the engine of the car from which you are getting a boost. Rev the engine slightly for a few seconds.

Step 10: Start your engine and remove all of the booster cable clamps. Remove them in the reverse order they were applied. Start by removing the black negative clamp on the engine of your car, then remove the black negative clamp from the booster car. After that remove the red clamp from the booster car and then lastly remove the red clamp from your car.
