How to disengage the automatic locking mode
Ford Motor Company recommends that all safety belt assemblies
and attaching hardware should be inspected by a qualified
technician after any collision. Safety belt assemblies not in use during a
collision should also be inspected and replaced if either damage or
improper operation is noted.
Disconnect the combination lap/shoulder belt and allow it to retract
completely to disengage the automatic locking mode and activate the
vehicle sensitive (emergency) locking mode.
After any vehicle collision, the front passenger and rear outboard
seat belt systems must be checked by a qualified technician to
verify that the "automatic locking retractor" feature for child seats is
still functioning properly. In addition, all seat belts should be checked
for proper function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the seat belt assembly "automatic locking retractor" feature or
any other seat belt function is not operating properly when checked
according to the procedures in Workshop Manual.
Failure to replace the Belt and Retractor assembly could
increase the risk of injury in collisions.
