FORD 2012 F-550 v.3 - Manual (Page 173)

Before you can reach and latch a combination lap and shoulder belt
(with a cinch tongue) into the buckle, you may have to lengthen the lap
belt portion of it.
1. To lengthen the lap belt, pull
some webbing out of the shoulder
belt retractor.
2. While holding the webbing below
the tongue, grasp the tip (metal
portion) of the tongue so that it is
parallel to the webbing and slide the
tongue upward.
3. Provide enough lap belt length so that the tongue can reach the
buckle.
How to fasten the cinch tongue
1. Pull the combination lap and shoulder belt from the retractor so that
the shoulder belt portion of the safety belt crosses your shoulder and
chest.
2. Be sure the belt is not twisted. If the belt is twisted, remove the twist.
3. Insert the belt tongue into the proper buckle for your seating position
until you hear a snap and feel it latch.
4. Make sure the tongue is securely fastened to the buckle by pulling on
the tongue.
WARNING: The lap belt should fit snugly and as low as possible
around the hips, not across the waist.
WARNING: Front and rear seat occupants, including pregnant
women, should wear safety belts for optimum protection in an
accident.
WARNING: Each seating position in your vehicle has a specific
safety belt assembly which is made up of one buckle and one
tongue that are designed to be used as a pair. 1) Use the shoulder belt
on the outside shoulder only. Never wear the shoulder belt under the
arm. 2) Never swing the safety belt around your neck over the inside
shoulder. 3) Never use a single belt for more than one person.
