How to Jump Start a Ford Bronco Sport

1. Pull back the red rubber boot and clamp the positive (+) jumper 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. Attach the negative (-) jumper cable to the negative (-) terminal of the booster vehicle battery.
4. Make the last negative (-) connection to an exposed metal part of the disabled engine, away from the battery and fuel injection system, or to a ground point.
5. Start the booster vehicle and keep engine speed between 2000 RPM and 3000 RPM on the tachometer.
6. Start the disabled vehicle, then run both engines for three more minutes before disconnecting.
7. Remove the jumper cables in the reverse order from how they were connected.

• Use only a 12 volt supply and park the booster vehicle close to the hood without the vehicles touching.
• If you use a jump pack or booster box, follow the manufacturer's instructions.
• Do not switch the headlamps on when disconnecting the cables; the peak voltage could blow the bulbs.
