SERVICE MANUAL UPDATE
The Driver Information Center System Check Table and Circuit Operation contain inaccurate information. The Driver Information Center lights all segments at once, not sequentially, upon power-up. Please make the following corrections to your copies of the 1987, 1988 and 1989 Pontiac 6000 Chassis Service Manuals.

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.
