FORD 2004 Expedition v.1 - Manual (Page 183)

Never let a passenger hold a child on his or her lap while the
vehicle is moving. The passenger cannot protect the child from
injury in a collision.
Always follow the instructions and warnings that come with any infant or
child restraint you might use.
Children and safety belts
If the child is the proper size, restrain the child in a safety seat.
Children who are too large for child safety seats (as specified by your
child safety seat manufacturer) should always wear safety belts.
Follow all the important safety restraint and air bag precautions that
apply to adult passengers in your vehicle.
If the shoulder belt portion of a combination lap and shoulder belt can
be positioned so it does not cross or rest in front of the child’s face or
neck, the child should wear the lap and shoulder belt. Moving the child
closer to the center of the vehicle may help provide a good shoulder belt
fit.
Do not leave children, unreliable adults, or pets unattended in
your vehicle.
Child booster seats
Children outgrow a typical convertible or toddler seat when they weigh
40 pounds and are around 4 years of age. Although the lap/shoulder belt
will provide some protection, these children are still too small for
lap/shoulder belts to fit properly, which could increase the risk of serious
injury.
To improve the fit of both the lap and shoulder belt on children who
have outgrown child safety seats, Ford Motor Company recommends use
of a belt-positioning booster.
Booster seats position a child so that safety belts fit better. They lift the
child up so that the lap belt rests low across the hips and the knees
bend comfortably. Booster seats also make the shoulder belt fit better
and more comfortably for growing children.
