How to Jump Start a Ford F-150 Lightning

1. Find the jumper cable symbols on the right-hand side luggage compartment cover and remove the cover.
2. Remove the red cap and connect the positive (+) jumper cable to the positive (+) jump point of the discharged battery vehicle.
3. Connect the other end of the positive (+) cable to the positive (+) terminal of the booster vehicle battery.
4. Connect the negative (-) cable to the negative (-) terminal of the booster vehicle battery.
5. Make the final negative (-) connection to the negative (-) ground point of the discharged battery vehicle.
6. Run the booster vehicle engine at a moderately high speed and move the low charge vehicle's selector lever to park (P).
7. Switch on the ready to drive mode, then run both vehicles at least three minutes before disconnecting the cables in reverse order.

• Do not connect the negative jumper cable to any other part of your vehicle; use the ground point.
• Keep the cables clear of moving parts.
• Do not switch the headlamps on when disconnecting the cables, as the peak voltage could damage the bulbs.
