This bulletin has been revised to correct the models affected. 1990 Electras/LeSabres are being omitted as Buick does not offer SIR on these models. Please discard 90-10-1 and replace it with 90-10-1A.
This bulletin is being issued to inform dealers that the window shade slack comfort feature on the front lap shoulder belt restraint system will not be available on the vehicles listed above. All dealership personnel should be aware of this change.
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.
