3. Tighten the tether strap
according to the child seat
manufacturer’s instructions.
If the safety seat is not anchored properly, the risk of a child being
injured in a collision greatly increases.
Child booster seats
The belt-positioning booster (booster seat) is used to improve the fit of
the vehicle safety belt. Children outgrow a typical child seat (e.g.,
convertible or toddler seat) when they weigh about 40 lb (18 kg) and are
around four (4) years of age. Consult your child safety seat owner guide
for the weight, height, and age limits specific to your child safety seat.
Keep your child in the child safety seat if it properly fits the child,
remains appropriate for their weight, height and age AND if properly
secured to the vehicle.
Although the lap/shoulder belt will provide some protection, children
who have outgrown a typical child seat are still too small for lap/shoulder
belts to fit properly, and wearing an improperly fitted vehicle safety belt
could increase the risk of serious injury in a crash. 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 vehicle lap/shoulder safety belts fit
better. They lift the child up so that the lap belt rests low across the hips
and the knees bend comfortably at the edge of the cushion, while
minimizing slouching. Booster seats may also make the shoulder belt fit
better and more comfortably. Try to keep the belt near the middle of the
shoulder and across the center of the chest. Moving the child closer (a
few centimeters or inches) to the center of the vehicle, but remaining in
the same seating position, may help provide a good shoulder belt fit.
