Hyundai Tucson: Maintenance / Battery

WARNING

To prevent serious injury or death to you or bystanders 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, it is highly combustible, and may explode if ignited.

Keep batteries out of reach of children.

Batteries contain sulfuric acid that 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.

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

NOTICE

To prevent battery damage:

  • Always fully charge the battery and store indoors when you do not plan to use the vehicle for a long time if the outside temperature is low enough to cause the battery to freeze.
  • Always fully charge the battery to prevent battery case damage in low temperature areas.
  • Never connect unauthorized devices to the battery.
