Consult an authorized HYUNDAI dealer to replace most vehicle light bulbs. It is difficult to replace vehicle light bulbs because other parts of the vehicle must be removed before you can get to the bulb. This is especially true for removing the headlamp assembly to get to the bulb(s).
Removing/installing the headlamp assembly can result in damage to the vehicle.
Information
After heavy driving, rain or washing, headlamp and trunk lenses could appear frosty. This condition is caused by the temperature difference between the lamp inside and the outside temperature. This is similar to the condensation on your windows inside your vehicle during the rain and doesn’t indicate a problem with your vehicle. If the water leaks into the lamp bulb circuitry, have your vehicle checked by an authorized HYUNDAI dealer.
Information - Desiccant (if equipped)
This vehicle is equipped with desiccant to reduce fogging inside the headlamp due to moisture.
The desiccant is consumable and its performance may change based on the used period or environment.
If fogging inside the headlamp due to moisture continues for a long time, have your vehicle checked by an authorized HYUNDAI dealer.
