How to Jump Start a Ford Fusion Hybrid

1. Remove the cap from the positive prong on your vehicle, then clip the positive (+) cable to the positive (+) terminal of the discharged battery.
2. Attach 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 last negative (-) connection to exposed metal on the stalled engine, away from the battery and fuel injection, or to a ground 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 vehicles three more minutes, then remove the cables in reverse order of connection.

• Check the instrument cluster for the Ready to Drive light, as the gasoline engine may not start while the electric motor runs.
• After disconnecting, leave the disabled vehicle in Ready to Drive mode for several minutes to charge the 12V battery.
