Seating and Safety Restraints
Center seating location
When installing a child safety seat in the front center position, route the
tether strap over the center arm rest and clip it to the center anchor.
If the tether strap is clipped incorrectly, the child safety seat may not be
retained properly in the event of a collision.
4. Tighten the child safety seat tether strap according to the
manufacturer's instructions.
If the safety seat is not anchored properly, the risk of a child being
injured in a collision greatly increases.
If your child restraint system is equipped with a tether strap, and the
child restraint manufacturer recommends its use, Ford also recommends
its use.
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.
