Jump starting can be dangerous if done incorrectly. Follow the jump starting procedure in this section to avoid serious injury or damage to your vehicle. If in doubt about how to properly jump start your vehicle, we strongly recommend that you have a service technician or towing service do it for you.
WARNING
To prevent SERIOUS INJURY or DEATH to you or bystanders, always follow these precautions when working near or handling the battery:
Always read and follow instructions carefully when handling a battery.
Wear eye protection designed to protect the eyes from acid splashes.
Keep all flames, sparks, or smoking materials away from the battery.
Hydrogen is always present in battery cells, is highly combustible, and may explode if ignited.
Keep batteries out of reach of children.
Batteries contain sulfuric acid which is highly corrosive. Do not allow acid to contact your eyes, skin or clothing. 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, thoroughly wash the area. If you feel pain or a burning sensation, get medical attention immediately.
- When lifting a plastic-cased battery, excessive pressure on the case may cause battery acid to leak. Lift with a battery carrier or with your hands on opposite corners.
- Do not attempt to jump start your vehicle if your battery is frozen.
- NEVER attempt to recharge the battery when the vehicle’s battery cables are connected to the battery.
- The electrical ignition system works with high voltage. NEVER touch these components with the engine running or when the ignition switch is in the ON position.

CALIFORNIA PROPOSITION 65 WARNING
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer, birth defects and reproductive harm. Batteries also contain other chemicals known to the State of California to cause cancer. Wash hands after handling.
CAUTION
- When you do not use the vehicle for a long time in a low temperature area, disconnect the battery and keep it indoors.

For best battery service
- Keep the battery securely mounted.

- Keep the terminals and connections clean, tight, and coated with petroleum jelly or terminal grease.
- Rinse any spilled acid from the battery immediately with a solution of water and baking soda.
Battery recharging
By battery charger
Your vehicle has a maintenance-free, calcium-based battery.
- If the battery becomes discharged in a short time (because, for example, the headlights or interior lights were left on while the vehicle was not in use), recharge it by slow charging (trickle) for 10 hours.
- If the battery gradually discharges because of high electric load while the vehicle is being used, recharge it at 20-30A for two hours.
WARNING
Always follow these instructions when recharging your vehicle’s battery to avoid the risk of SERIOUS INJURY or DEATH from explosions or acid burns:
- Before performing maintenance or recharging the battery, turn off all accessories and place the ignition switch in the LOCK/OFF position.
- Keep all flames, sparks, or smoking materials away from the battery.
- Always work outdoors or in an area with plenty of ventilation.
- Wear eye protection when checking the battery during charging.
- The battery must be removed from the vehicle and placed in a well ventilated area.
- Watch the battery during charging, and stop or reduce the charging rate if the battery cells begin boiling violently.
- The negative battery cable must be removed first and installed last when the battery is disconnected. Disconnect the battery charger in the following order: Turn off the battery charger main switch. Unhook the negative clamp from the negative battery terminal. Unhook the positive clamp from the positive battery terminal.
- Always use a genuine HYUNDAI approved battery when you replace the battery.
