Seating and safety restraints
Child and infant or child safety seats
Use a safety seat that is recommended for the size
and weight of the child. Carefully follow all of the
manufacturer's instructions with the safety seat you
put in your vehicle. If you do not install and use the
safety seat properly, the child may be injured in a
sudden stop or collision.
When installing a child safety seat:
Review and follow
the information
presented in the Air
Bag Supplemental
Restraint System
section in this
chapter.
Use the correct
safety belt buckle for that seating position.
Insert the belt tongue into the proper buckle until
you hear a snap and feel it latch. Make sure the
tongue is securely fastened in the buckle.
Keep the buckle release button pointing up and
away from the safety seat, with the tongue
between the child seat and the release button, to
prevent accidental unbuckling.
Place seat back in upright position.
Put the safety belt in the automatic locking mode.
Refer to Automatic locking mode.
Ford recommends the use of a child safety seat
having a top tether strap. Install the child safety seat
in a seating position which is capable of providing a
tether anchorage. For more information on top
tether straps, refer to Attaching safety seats with
tether straps.
