FORD 2003 F-550 v.3 - Manual (Page 84)

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 seat belt and
increase the risk of injury in a collision.
Lap belts
Adjusting the lap belt
The lap belt should fit snugly and as low as possible around the
hips, not across the waist.
• 1st row center seating position
The lap belt does not adjust automatically.
Insert the tongue into the correct
buckle (the buckle closest to the
direction the tongue is coming
from). To lengthen the belt, turn the
tongue at a right angle to the belt
and pull across your lap until it
reaches the buckle. To tighten the
belt, pull the loose end of the belt
through the tongue until it fits
snugly across the hips.
Shorten and fasten the belt when
not in use.
• 2nd row center seating position (if equipped)
The lap belt will adjust automatically. To fasten, grasp the tongue, and
with a continuous motion, pull out enough webbing to buckle the tongue
