Bring the Engines Close
First, bring the working car engine close to your own. Parked either parallel or facing your car is fine, but ideally, the two engines should be within two feet of one another.
Shut off Power:
Next, turn both vehicles off.
Connect Positive to Positive:
Start by connecting the positive (often red) clamps of the jumper cables to the positive terminals of your battery. These are often marked, but they can be hard to see. Be sure to look closely to ensure that you are connecting to the right portion of the battery.
Connect Negative to Negative:
Connect the negative (often black) clamps of the jumper cable to the negative terminal of the live battery. In your car, stick the negative terminal to an unpainted metal surface.
