High Intensity Discharge (HID)
Lighting

CAUTION:
The low beam high intensity discharge

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.

CAUTION:
Halogen bulbs have pressurized gas

scratch the bulb. You or others could be
injured. Be sure to read and follow the
instructions on the bulb package.
