Seatbelts
Ford Motor Company recommends that all
safety belt assemblies in use in vehicles
involved in a crash be replaced. However, if
the crash 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 crash should
also be inspected and replaced if either
damage or improper operation is noted.
Properly care for safety belts. See Vehicle
Care (page 286).
