General Motors bulletins are intended for use by professional
technicians, not a "do-it-yourselfer". They are written to inform those
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 a General
Motors dealer servicing your brand of General Motors vehicle for
information on whether your vehicle may benefit from the information.
