indicate a problem with your vehicle.  
When moisture condenses in the lamp,  
it will be removed after driving with the  
headlamp on. The removable level may  
differ depending on lamp size, lamp  
position and environmental condition.  
However, if moisture is not removed, we  
recommend that your vehicle is inspected  
by an authorised HYUNDAI dealer.
