Operational and Functional Checks

Keep sharp objects and potentially damaging objects away from the seat belts.
Avoid bending or damaging any portion of the buckle or the latch plate.
Do not bleach or dye the belt webbing. Use only mild soap and water in order to clean the belts.
When installing the seat belt anchor bolts and the screws, start the bolts and the screws by hand in order to prevent crossthreading.
Do not attempt any repairs on the retractor mechanisms or the covers. Replace any defective assemblies with new assemblies.
Replace any belts that are cut or damaged in any way.

Inspect all seat belt anchor bolts and the screws in order to verify that they are secure.
Inspect the seat belt buckle. The buckle must lock and unlock easily.
After inserting the latch into the buckle, tug sharply on the belt. The buckle must remain locked.
Fully extend the shoulder belt portion to make sure that there is no twisting or tears in the belt.
Let the shoulder belt retract fully. The belt should retract easily.
