6. While pushing down with your
knee on the child seat pull up on
the shoulder belt portion to tighten
the lap belt portion of the
combination lap and shoulder belt.
7. Allow the safety belt to retract and remove any slack in the belt to
securely tighten the child safety seat in the vehicle.
8. Attach the tether strap (if the child seat is equipped). Refer to
Attaching child safety seats with tether straps later in this chapter.
9. Before placing the child into the
child seat, forcibly pull the child
seat forward and back to make sure
that the seat is held securely in
place. To check this, grab the seat
at the belt path and attempt to
move it side to side and forward and
back. There should be no more than
1 inch (2.5 cm) of movement for
proper installation.
10. Check from time to time to be sure that there is no slack in the
lap/shoulder belt. The shoulder belt must be snug to keep the lap belt
tight during a collision.
11. Ford recommends checking with a NHTSA Certified Child Passenger
Safety Technician (CPST) to make certain the child restraint is properly
installed. In Canada, check with your local St. John Ambulance office for
referral to a CPST.
