High Intensity Discharge (HID)
Lighting
CAUTION:
{
The low beam high intensity discharge lighting
system operates at a very high voltage. If you
try to service any of the system components,
you could be seriously injured. Have your
dealer or a qualified technician service them.
Your vehicle may have HID headlamps. After your
vehicle's HID headlamp bulb has been replaced,
you may notice that the beam is a slightly different
shade than it was originally. This is normal.
