FORD 2013 F-550 v.1 - Manual (Page 40)

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.
Fastening the Cinch Tongue
WARNING: The lap belt should fit snugly and as low as possible
around the hips, not across the waist.
1. Pull the 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.
While you are fastened in the safety belt, the lap and shoulder belt with
a cinch tongue adjusts to your movement. However, if you brake hard,
turn hard, or if your vehicle receives an impact of 5 mph (8 km/h) or
more, the safety belt will become locked and help reduce your forward
movement.
