If this warning light comes on while the engine is running, the battery is not being charged. Immediately turn off all electrical accessories. Try not to use electrically operated controls, such as the power windows. Keep the engine running; starting the engine will quickly discharge the battery.

In this case, have your vehicle inspected by an authorized HYUNDAI dealer.
