This is necessary to remove the remaining slack that will exist once the
extra weight of the child is added to the child restraint. It also helps
to achieve the proper snugness of the child seat to your vehicle.
Sometimes, a slight lean toward the buckle will additionally help to
remove remaining slack from the belt.
9. Attach the tether strap (if the child seat is equipped). See Using
Tether Straps in this chapter.
10. Before placing the child in the
seat, forcibly move the seat forward
and back to make sure the seat is
securely held 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 centimeters) of movement for proper installation.
Ford recommends checking with a NHTSA Certified Child Passenger
Safety Technician to make certain the child restraint is properly installed.
In Canada, check with your local St. John Ambulance office for referral
to a Child Passenger Safety Technician.

front of an active airbag.
WARNING: Always use both lap and shoulder safety belt in the
Regular Cab center seating position if applicable.
