<TD align=left width=778><FONT size=1>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.
