Seating and Safety Restraints
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.
Do not leave children, unreliable adults, or pets unattended in
your vehicle.
To improve the fit of lap and shoulder belts on children who have
outgrown child safety seats, Ford recommends use of a belt-positioning
booster seat that is labeled as conforming to all applicable Federal motor
vehicle safety standards. Belt-positioning booster seats raise the child
and provide a shorter, firmer seating cushion that encourages safer
seating posture and better fit of lap and shoulder belts on the child.
A belt-positioning booster seat should be used if the shoulder belt rests
in front of the child's face or neck, or if the lap belt does not fit snugly
on both thighs, or if the thighs are too short to let the child sit all the
way back on the seat cushion when the lower legs hang over the edge of
the seat cushion. You may wish to discuss the special needs of your child
with your pediatrician.
Child booster seats
Children outgrow a typical convertible or toddler seat when they weigh
40 lb. (18 kg) 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.
When children should use booster seats
Children need to use booster seats from the time they outgrow the
toddler seat until they are big enough for the vehicle seat and
lap/shoulder belt to fit properly. Generally this is when they weigh about
80 lb. (36 kg) (about 8 to 12 years old).
