How to Jump Start a Ford Mustang Mach-E

1. Remove the rear and left side front luggage compartment covers to reach the booster cable connection points.
2. 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 (-) jumper 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, then unlock the driver door.
6. Run the booster vehicle engine at a moderately high speed, put the discharged vehicle in park (P), and switch on ready to drive mode.
7. Run both vehicles for at least three minutes, then disconnect 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 any moving parts.
• Do not switch the headlamps on when disconnecting the cables because the peak voltage could damage the bulbs.
