FORD 2011 F-550 v.2 - Manual (Page 169)

How to use the automatic locking mode
• Buckle the combination lap and
shoulder belt.
• Grasp the shoulder portion and
pull downward until the entire
belt is pulled out.
• Allow the belt to retract. As the belt retracts, you will hear a clicking
sound. This indicates the safety belt is now in the automatic locking
mode.
How to disengage the automatic locking mode
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.
WARNING: After any vehicle collision, the front passenger and
rear outboard safety belt systems must be checked by an
authorized dealer to verify that the “automatic locking retractor”
feature for child seats is still functioning properly. In addition, all safety
belts should be checked for proper function.
