Hyundai Sonata: Maintenance / Light Bulbs

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.

WARNING

Absorbent

This vehicle contains a dehumidifying dehumidifier inside the headlamp to mitigate the blurring of the headlamp due to moisture.

The desiccant is a consumable part and its performance may change depending on the usage time or environment.

If the inside of the headlamp continues to become cloudy due to moisture, we recommend that you consult an authorized HYUNDAI dealer.

The desiccant is a consumable part and cannot be guaranteed.
