FORD 2003 F-550 v.1 - Manual (Page 90)

The shoulder belt should cross the chest, resting snuglyon the center of
the shoulder. The lap belt should rest low and snug across the hips,
never up high across the stomach.
If the booster seat slides on the vehicle seat, placing a rubberized mesh
sold as shelf or carpet liner under the booster seat mayimprove this
condition.
The importance of shoulder belts
Using a booster without a shoulder belt increases the risk of a child’s
head hitting a hard surface in a collision. For this reason, you should
never use a booster seat with a lap belt only. It is best to use a booster
seat with lap/shoulder belts in the back seat- the safest place for children
to ride.
Follow all instructions provided bythe manufacturer of the
booster seat.
Never put the shoulder belt under a child’s arm or behind the
back because it eliminates the protection for the upper part of
the bodyand mayincrease the risk of injuryor death in a collision.
Never use pillows, books, or towels to boost a child. Theycan
slide around and increase the likelihood of injuryor death in a
collision.
