How to Jump Start a Hyundai Kona

1. Park the vehicles close enough for the cables to reach without touching, shift both into P (Park), apply the parking brake and turn both vehicles OFF.
2. Switch off all electrical devices, open the hood and remove the engine compartment fuse box cover.
3. Connect one jumper cable to the red, positive (+) battery terminal of your vehicle (1).
4. Connect the other end of that cable to the red, positive (+) battery/jumper terminal of the assisting vehicle (2).
5. Connect the second cable to the black, negative (-) battery/jumper terminal of the assisting vehicle (3).
6. Connect the other end of the second cable to the chassis ground of your vehicle (4).
7. Start the assisting vehicle, let it run at about 2,000 RPM for a few minutes, then start your vehicle.
8. Disconnect the cables in exact reverse order: (4), (3), (2), then (1).

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