How to Jump Start a Hyundai Kona Electric

1. Remove the motor compartment fuse box cover.
2. Connect one jumper cable to the red, positive (+) jumper terminal of your vehicle (1).
3. Connect the other end of that cable to the red, positive (+) battery/jumper terminal of the assisting vehicle (2).
4. Connect the second cable to the black, negative (-) battery/jumper terminal of the assisting vehicle (3).
5. Connect the other end of the second cable to the black, negative (-) chassis ground of your vehicle (4).
6. Start the assisting vehicle and let it run a few minutes, then start your vehicle.
7. Disconnect the cables in exact reverse order: (4), then (3), then (2), then (1).

• Do not connect the cable to the negative (-) jumper terminal of the discharged battery; a spark could make the battery explode.
• Keep your vehicle running at least 30 minutes at idle or driving; a fully discharged battery may need up to 60 minutes.
• Use only a 12 V power supply and never push-start the vehicle.
