GM Service Manual Online
For 1990-2009 cars only

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 and fog lamps. After your vehicle's HID headlamp or fog lamp bulb has been replaced, you may notice that the beam is a slightly different shade than it was originally. This is normal.
