FORD 2012 F-150 Raptor v.3 - Manual (Page 223)

6. Allow the belt to retract to remove slack. The belt will click as it
retracts to indicate it is in the automatic locking mode.
7. Try to pull the belt out of the retractor to make sure the retractor is
in the automatic locking mode (you should not be able to pull more belt
out). If the retractor is not locked, unbuckle the belt and repeat Steps 5
and 6.
8. Remove remaining slack from the
belt. Force the seat down with extra
weight, e.g., by pressing down or
kneeling on the child restraint while
pulling up on the shoulder belt in
order to force slack from the belt.
This is necessary to remove the
remaining slack that will exist once
the additional weight of the child is
added to the child restraint. It also
helps to achieve the proper
snugness of the child seat to the
vehicle. Sometimes, a slight lean
towards the buckle will additionally
help to remove remaining slack from the belt.
9. Attach the tether strap (if the child seat is equipped). Refer to
Attaching child safety seats with tether straps later 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 cm) of
movement for proper installation.
11. Ford recommends checking with a NHTSA Certified Child Passenger
Safety Technician (CPST) to make certain the child restraint is properly
installed.
