NORMAL OPERATING CONDITION
Description
INFOID:0000000010121371
LED HEADLAMP
• LED brightness and color may slightly change until the temperature becomes stable. This is not malfunction.
• Illumination time lag may occur between right and left. This is not malfunction.
• Brightness may be reduced due to aged deterioration of LED.
• Because of the dummy portion of connecting part of front combination lamp, water may be seemed as if it
enters in headlamp after the vehicle is washed or after the rain. But, actually water is not entered in head-
lamp, and this is not malfunction.
AUTO LIGHT SYSTEM
The headlamp may not be turned ON/OFF immediately after passing dark area or bright area (short tunnel,
sky bridge, shadowed area, etc.) while using the auto light system. This is caused by the control difference.
This is normal.
