NORMAL OPERATING CONDITION
DescriptionINFOID:0000000003774368
XENON HEADLAMP
 Brightness and the color of light may change slightly immediately after turning the headlamp ON until the
xenon bulb becomes stable. This is normal.
 Illumination time lag may occur between right and left. This is normal.
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 causes for the control difference. This
is normal.
