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 Hyundai Accent 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.

NOTICE

Always follow these instructions when handling your vehicle's battery to prevent damage to your battery:

• When you do not use the vehicle for a long time in a low temperature area, disconnect the battery and keep it indoors.
• Always charge the battery fully to help prevent battery case damage in low temperature areas.
• Prevent liquid from wetting the battery terminals. The performance of the battery may be degraded and may cause injury. Be cautious when loading liquid in the trunk.
• Do not tilt the battery.
• If you connect unauthorized electronic devices to the battery, the battery may be discharged. Never use unauthorized devices.

Small maintenance note for Hyundai Accent owners: keep the terminals clean and tight, and have the charging system checked if you notice slow cranking or frequent jump starts.

For Best Battery Service

• Keep the battery securely mounted to help prevent vibration-related damage and intermittent electrical issues in your Hyundai Accent.
• Keep the battery top clean and dry to reduce corrosion and unwanted current leakage across the case.
• Keep the terminals and connections clean, tight, and coated with petroleum jelly or approved terminal grease to slow corrosion and maintain reliable starting.
• Rinse any spilled acid from the battery immediately with a solution of water and baking soda, then wipe the area dry.

Battery Recharging

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 to 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:
  (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.
• Always use a genuine HYUNDAI approved battery when you replace the battery.

By jump starting

After a jump start from a good battery, drive the vehicle for 20-30 minutes before it is shutoff. The vehicle may not restart if you shut it off before the battery had a chance to adequately recharge. See "Jump Starting" in chapter 6 for more information on jump starting procedures. As an extra reminder for Hyundai Accent owners, minimizing repeated short trips and ensuring lights/accessories are off after parking can help prevent low-battery situations.

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