safety belt and let it go back all the way. The safety
belt will move freely again and be ready to work for an
adult or larger child passenger.
Securing a Child Restraint in a
Center Rear Seat Position
If you have a extended cab or crew cab pickup, you can
secure a child restraint in the center rear seat position.
Crew Cab
When you secure a child restraint in the center rear
seat position of a crew cab, you'll be using a
lap-shoulder belt that works the same way as the safety
belts in the rear outside seat positions. For instructions
on how to secure a child restraint using a lap-shoulder
belt see Securing a Child Restraint in a Rear Outside
Seat Position on page 1-49.
Extended Cab
There is limited space in the rear seating area of an
extended cab model. If you want to secure a child
restraint in a rear seat position of an extended cab
model, especially in the rear center seat position,
be sure to study the instructions that came with your
child restraint to see if there is enough room to secure
your seat properly.
When you secure a child restraint in the center rear
seat position of an extended cab, you'll be using the lap
belt. Be sure to follow the instructions that came with
the child restraint. Secure the child in the child restraint
when and as the instructions say. See Top Strap on
page 1-42 if the child restraint has one.
If your child restraint is equipped with the latch system,
see lower Anchorages and Top Tethers for Children
(LATCH System) on page 1-46.
