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. 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
one inch of movement for proper
installation.
9. 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.
Installing child safety seats in the front row lap belt seating
positions (SuperCab and SuperCrew)
Installing a child safety seat in the front row lap seating position
should be avoided if at all possible. The passenger sensing
system does not recognize child seats in the front center seating
position.
Never place a rear-facing child seat in the front center seating
position of a vehicle with rear seating positions.
1. Lengthen the lap belt. To lengthen the belt, hold the tongue so that its
bottom is perpendicular to the direction of webbing while sliding the
tongue up the webbing.
