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.
If there is a malfunction with either the alternator or electrical charging system:
1.Drive carefully to the nearest safe location and stop your vehicle.
2.Turn the engine off and check the alternator drive belt for looseness or breakage.
If the belt is adjusted properly, there may be a problem in the electrical charging system.
In this case, have your vehicle inspected by an authorized HYUNDAI dealer.
