In addition to the labels mentioned, at various places around the inside of the vehicle, watch for airbag identification tags. The number and placement of tags depend on vehicle equipment. Belt webbing should be visually and operationally checked that it automatically retracts, the belt latch mechanism (guide stop), the seatbelt locking tongue, anchoring points and components for wear and damage, together and separately. Fully extend the belt webbing off the automatic belt retractor and check for soiling and wash in a solution of mild soap and water, if necessary. Check webbing for damage; activated pyrotechnic seatbelts do not retract and need be replaced. The occupant or vehicle movement activates the two locking functions of the retractor. Test the first operation by yanking the belt out sharply - the belt must lock while you're pulling it out. If it's not OK, replace the belt and latch. To carry out the second function, securely fasten the belt, drive on a clear and level surface to 12 mph, and fully apply the brake; the seatbelt should become locked as the vehicle stops. The latch for the seatbelts must be inspected for cracks and fractures and used to test the function for proper engagement and release. Examine seatbelt extenders, guides and lock tongues for damage and replace as necessary. Examine lock straps, height adjusters and anchor points for damage and test for proper operation. Replace any damaged or malfunctioning parts.
