  • Page 40 As the seat belts lose much of their strength when exposed to violent stretching, they should be replace after any collision, even though they may appear to be undamaged. Never repair the belt on you own; have this done by an authorized Volvo dealer only. Maintenance Check periodically that the anchor bolts are secure and that the belts are in good condition.
