FORD 2012 F-550 v.1 - Manual (Page 179)

Front safety belt height adjustment
Your vehicle has safety belt height
adjustments at the front outboard
seating positions. Adjust the height
of the shoulder belt so the belt rests
across the middle of your shoulder.
To adjust the shoulder belt height,
pull on the center button and slide
the height adjuster down. Release
the button and pull down on the
height adjuster to make sure it is
locked in place. To adjust the belt
upward, slide the adjuster up and then pull down on the height adjuster
to make sure it is locked in place
WARNING: Position the safety belt height adjusters so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the safety
belt and increase the risk of injury in a collision.
Safety belt extension assembly
If the safety belt is too short when fully extended, a safety belt extension
assembly can be obtained from an authorized dealer.
Use only extensions manufactured by the same supplier as the safety
belt. Manufacturer identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if the safety belt is too
short for you when fully extended.
WARNING: Do not use extensions to change the fit of the
shoulder belt across the torso.
Safety belt warning light and indicator chime
The safety belt warning light illuminates in the instrument cluster and a
chime sounds to remind the occupants to fasten their safety belts.
