Seating and Safety Restraints
there are no nicks, tears or cuts. Replace if necessary. All safety belt
assemblies, including retractors, buckles, front safety 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 LATCH and tether anchors, and attaching
hardware, should be inspected after a collision. Ford Motor Company
recommends that all safety belt assemblies in use in vehicles involved in
a collision be replaced. However, if the collision was minor and an
authorized dealer 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.
Failure to inspect and if necessary replace the safety belt
assembly under the above conditions could result in severe
personal injuries in the event of a collision.
For proper care of soiled safety belts, refer to Interior in the Cleaning
chapter.
