How to Jump Start a Ford Expedition

1. Park the booster vehicle close to the hood of the disabled vehicle without letting the two vehicles touch, and use only a 12 volt supply.
2. Pull the red rubber boot backward and connect the positive (+) jumper cable to the positive (+) terminal of the discharged battery.
3. Connect the other end of the positive (+) cable to the positive (+) terminal of the booster vehicle battery.
4. Connect the negative (-) jumper cable to the negative (-) terminal of the booster vehicle battery.
5. Connect the other negative (-) end to an exposed metal part of the disabled engine away from the battery and fuel injection system, or to a ground point.
6. Start the booster vehicle and keep engine speed between 2000 and 3000 RPM, then start the disabled vehicle.
7. Run both engines for an additional three minutes, then remove the cables in the reverse order of connection.

• Do not connect the negative jumper cable to any other part of your vehicle; use the ground point.
• If using a jump pack or booster box, follow the manufacturer's instructions.
• Do not switch the headlamps on when disconnecting the cables, as peak voltage could blow the bulbs.
