Safety belt maintenance
Inspect the safety belt systems periodically to make sure they work
properly and are not damaged. Inspect the safety belts to make sure
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front seat belt buckle
assemblies, buckle support assemblies (slide bar-if equipped), shoulder
belt height adjusters (if equipped), shoulder belt guide on seatback (if
equipped), child safety seat tether bracket assemblies (if equipped),
LATCH child seat tether anchors and lower anchors (if equipped), and
attaching hardware, should be inspected after a collision. Ford Motor
Company recommends that all safety belt assemblies used in vehicles
involved in a collision be replaced. However, if the collision was minor
and a qualified technician finds that the belts do not show damage and
continue to operate properly, they do not need to be replaced. Safety
belt assemblies not in use during a collision should also be inspected and
replaced if either damage or improper operation is noted.
