Jump starting can be dangerous if it is not performed correctly. Follow the jump starting procedure in this section to avoid serious injury or damage to your vehicle. If you are in doubt about how to start your vehicle correctly, we strongly recommend that you have a service technician or towing service do it for you.

WARNING

To avoid SERIOUS INJURY or DEATH to yourself or others, always follow these precautions when working near or handling the battery:

If acid gets into your eyes, flush your eyes with clean water for at least 15 minutes and get immediate medical attention. If acid gets on your skin, wash the area thoroughly. If you feel pain or burning, consult a doctor immediately.

  • When lifting a plastic-cased battery, excessive pressure on the case may cause battery acid leakage. Lift the battery with a battery carrier or with your hands on opposite corners.
  • Do not attempt to start your vehicle if the battery is frozen.
  • NEVER attempt to recharge the battery while the battery cables are connected to the battery.
  • The electronic ignition system operates with high voltage. NEVER touch these components when the engine is running or when the Engine Start/Stop button is in the ON position or when the ignition switch is in the ON position.

Jump Starting Procedure

Information

Your vehicle has a 12V maintenance-free battery located in the engine compartment. When attempting to start the vehicle from an external power source, open the hood and follow the procedure below.

1. Position the vehicles close enough for the jumper cables to reach, but do not allow the vehicles to touch.

2. Avoid fans or any moving parts in the engine compartment at all times, even when the vehicles are off.

3. Turn off all electrical devices such as the radio, lights, and air conditioner. Place both vehicles in P (Park) and set the parking brake. Turn off both vehicles.

4. Open the engine hood.

5. Connect the jumper cables in the exact sequence shown in the illustration. First, connect one end of the jumper cable to the red, positive (+) jump start terminal of your vehicle (1).

6. Connect the other end of the jumper cable to the red, positive (+) battery/jump terminal of the assisting vehicle (2).

7. Connect the second jumper cable to the black, negative (-) battery/ground of the assisting vehicle (3).

8. Connect the other end of the second jumper cable to the black, negative (-) ground on the chassis of your vehicle (4). Do not allow the jumper cables to contact anything other than the correct battery or jump terminal or correct ground. Do not lean over the battery when making connections.

9. Start the engine of the assisting vehicle and let it run at approximately 2000 rpm for several minutes. Then start your vehicle.

10. Keep the vehicle running for at least 30 minutes at idle or while driving to make sure your battery receives enough charge to be able to start the vehicle on its own after the vehicle is stopped. A fully discharged battery may require up to 60 minutes of running time to fully recharge. If the vehicle is operated for less time, the battery may not restart.

If your vehicle does not start after several attempts, it probably requires service. In this case, contact qualified assistance. If the cause of battery discharge is not obvious, have your vehicle checked by an authorized HYUNDAI dealer.

Disconnect the jumper cables in the exact reverse order from which you connected them:

1. Disconnect the jumper cable from the black, negative (-) chassis ground of your vehicle (4).

2. Disconnect the other end of the jumper cable from the black, negative (-) battery/chassis ground of the assisting vehicle (3).

3. Disconnect the second jumper cable from the red, positive (+) battery/jumper terminal of the assisting vehicle (2).

4. Disconnect the other end of the jumper cable from the red, positive (+) jumper terminal of your vehicle (1).

Information

Improper battery disposal can be harmful to the environment and human health. Dispose of the battery in accordance with your local laws or regulations.

NOTICE

To prevent damage to your vehicle:

  • Use only a 12-volt power source (battery or jumper cable system) to jump start your vehicle.
  • Do not attempt to start your vehicle by push starting.

Information

The main latch is electronic type. It cannot be easily opened in the event of a power failure.

PLEDGE

  • Do not store the jumper cables in the bed floor, including under-bed storage.
  • If you have a lot of cargo placed in the bed area, all cargo must be removed to access the under-bed storage and the jumper cables.
