Seat Belt Systems: Description and Operation

A Continuous Loop Single Retractor Restraint System is used on all models. If seat belts or shoulder belts are removed for any reason, the anchor bolts should be tightened to 39-55 Nm (28-35 ft lbs).

Belt assemblies must be installed in matched sets as received and must not be interchanged between vehicle models.

If a component portion other than the removable D-ring cover (buckle portion, retractor portion, etc.) of a seat belt or shoulder belt assembly is nonfunctional or damaged, the entire assembly (buckle, tongue and shoulder harness portions) must be replaced.

The replacement assembly must be installed as a matched set and the manufacturer's identification on the label of the retractor webbing must match the manufacturer's identification on the buckle base.

NOTE: Seat belt assemblies must be replaced after they have been subjected to loading by occupants in a collision.

The system incorporates buzzer and light warnings. The seat belt warning light will illuminate for about 6 seconds after the ignition switch is turned on, regardless of seat belt usage. The seat belt warning buzzer is grounded through the buckle switch of the driver's seat belt.

If the driver's seat belt is not fastened, the seat belt warning buzzer will sound for about six seconds.

However, when the driver's seat belt is fastened, the buzzer stops. This is because the buckle switch is turned OFF and the ground current is cut.
