How to Jump Start a Ford Fusion

1. Connect the positive (+) jumper cable to the positive (+) terminal of the discharged battery.
2. Connect the other end of the positive (+) cable to the positive (+) terminal of the booster vehicle battery.
3. Connect the negative (-) cable to the negative (-) terminal of the booster vehicle battery.
4. Make the final negative (-) connection to an exposed metal part of the stalled engine, away from the battery and fuel injection system, or to a ground connection point if available.
5. Start the booster vehicle and keep engine speed between 2000 and 3000 RPM, then start the disabled vehicle.
6. Run both engines for an additional three minutes, then remove the cables in reverse order of connection.

• Removal order: negative cable on disabled vehicle, negative on booster battery, positive on booster battery, positive on disabled battery.
• Let the engine idle for at least one minute after removing the cables.
