Battery
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.
Ě -
Wear eye protection designed to protect the eyes from acid splashes.
ğ -
Keep all flames, sparks, or smoking materials away from the battery.
ě -
Hydrogen is always present in battery cells, is highly combustible, and may explode if ignited.
Ĝ -
Keep batteries out of reach of children.
ĝ -
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 Engine Start/Stop button is in the ON position.
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.
-
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 liftgate.
-
Do not tilt the battery.
-
If you connect unauthorized electronic devices to the battery, the battery may be discharged. NEVER use unauthorized devices.

By battery charger
Your vehicle has a maintenance-free, calcium-based battery.
-
If the battery becomes discharged over a short time (because, for example, the headlights or interior lights are left on while the vehicle is not used), recharge it by slow charging (trickle) for 10 hours.
-
If the battery gradually discharges because of high electrical load while the vehicle is being used, recharge at 20-30 A for two hours.
To prevent the risk of serious injury or death from explosions or acid burns:
-
Before performing maintenance or recharging the battery, turn off all accessories and stop the engine.
-
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. Do not contact the battery. This may result in serious injury.
-
Remove the battery from the vehicle and place it in a well ventilated area.
-
Watch the battery during charging, and stop or reduce the charging rate if the battery cells begin boiling violently.
-
Remove the negative battery cable first and install it 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.
-
-
Do not open or remove the cap on top of the battery. This may cause leaks of internal electrolyte that could result in severe injury.
-
Absorbent Glass Mat (AGM) batteries are maintenance-free and should be serviced by an authorized HYUNDAI dealer. Only charge using fully automatic battery chargers that are specifically for AGM batteries.
By jump starting
After a jump start from a good battery, drive the vehicle for 30 minutes or operate at idle for at least 60 minutes before it is shut off. The vehicle may not restart if you shut it off before the battery has a chance to adequately recharge. For more information on jump starting procedures, refer to Jump Starting.
WL_TakingCareOfBatteryWarning_8
