Certain light duty pickup trucks and sport utility vehicles fail to conform to Federal Motor Vehicle Safety Standard No. 209, "Seat Belt Assemblies." One of the two sensors in the driver's and front passenger's seat belt retractors could be inoperative. The seat belt retractors will lock when the belt webbing is extracted during a crash; however, the mechanism that locks the seat belt retractor when the vehicle decelerates quickly, such as heavy braking, may not operate as intended.

Dealers will inspect the seat belt assemblies to determine proper vehicle sensor function. Owner notification is expected to begin during July 2004. Owners should contact GMC at 1-866-996-9463.
