fender and fascia openings. The headlamp lens
should have a minimum 0.5 mm (0.02 in) gap
between the lens and the body panel.

Note: In some cases, the forward mounting hole in the
headlamp housing may need to be slightly enlarged to
move the headlamp away from the fascia.
5. Adjust the headlamps on both sides, as necessary,
by loosening the fasteners and moving the front
corner of the headlamp away from the front
compartment opening. Reinstall the bolt while
holding the lamp in position. This will gain
clearance between the headlamp and the fascia.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
