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 has 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.
