Operational and Functional ChecksFront and Rear Seat Belt Retractors
Front and rear seat belt retractors will lock under the following conditions:
^ The vehicle exceeds a 15° angle
^ The vehicle exceeds 0.60 g of deceleration force
^ The webbing is pulled out of the retractor rapidly
^ During hard cornering or while descending a winding downhill grade
^ While braking to stop at a downhill intersection
All retractors will unlock when 25.4 mm (1 in) of the belt is fed back into the retractor.
Static Test
1. Remove the retractor assembly.
2. Tilt the retractor slowly.

Safety Belt Operational Checks
Front and Rear Restraints The front seats and rear seats have a three-point seat belt system with a seat belt retractor. The rear seat latch plate should move up and down easily on the belt. An audible click should be heard when the front or rear latch plate is inserted into the buckle. Inspect the attachment of the latch plate to the buckle by grasping the belt and pulling firmly. The belt should disconnect easily when the button on the buckle is pushed in.
