Seating and safety restraints
How to disengage the automatic locking mode
Ford 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 seat belt system at all outboard
seating positions (except driver, which has no "automatic locking
retractor" feature) 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.
