For best battery service

• Keep the battery securely mounted.
• Keep the battery top clean and dry.
• Keep the terminals and connections clean, tight, and coated with petroleum jelly or terminal grease.
• Rinse any spilled electrolyte from the battery immediately with a solution of water and baking soda.
• If the vehicle is not going to be used for an extended time, disconnect the battery cables.

WARNING - Battery dangers

Always read the following instructions carefully when handling a battery.

Keep lighted cigarettes and all other flames or sparks away from the battery.

Hydrogen, a highly combustible gas, is always present in battery cells and may explode if ignited.

Keep batteries out of the reach of children because batteries contain highly corrosive SULFURIC ACID. Do not allow battery acid to contact your skin, eyes, clothing or paint finish.

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

Wear eye protection when charging or working near a battery. Always provide ventilation when working in an enclosed space.

An inappropriately disposed battery can be harmful to the environment and human health. Dispose the battery according to your local law(s) or regulation.

• When lifting a plastic-cased battery, excessive pressure on the case may cause battery acid to leak, resulting in personal injury. Lift with a battery carrier or with your hands on opposite corners.

• The electrical ignition system works with high voltage. Never touch these components with the engine running or the ignition switched on.

Failure to follow the above warnings can result in serious bodily injury or death.• Never attempt to recharge the battery when the battery cables are connected.

CAUTION

• When you don’t use the vehicle for a long time in the low temperature, remove the battery and store it indoors.

• Always charge the battery fully to prevent the battery case damaged in low temperatures.

Battery recharging

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 - Recharging battery

When recharging the battery, observe the following precautions:
• The battery must be removed from the vehicle and placed in an area with good ventilation.
• Do not allow cigarettes, sparks, or flame near the battery.
• Watch the battery during charging, and stop or reduce the charging rate if the battery cells begin gassing (boiling) violently or if the temperature of the electrolyte of any cell exceeds 120°F (49°C).
• Wear eye protection when checking the battery during charging.
• Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.

WARNING

• Before performing maintenance or recharging the battery, turn off all accessories and stop the engine.
• The negative battery cable must be removed first and installed last when the battery is disconnected.
• Operation related to the battery should be done in an authorized HYUNDAI dealer.
