Securing a Child Restraint in a
Center Seat Position
(3rd, 4th and 5th Row)
1-58
If your child restraint is equipped with the LATCH
system, see Lower Anchorages and Top Tethers for
Children (LATCH System) on page 1-52 . See Top Strap
on page 1-49 if the child restraint has one.
For vehicles with fourth and/or fifth rows, there are no
top strap anchors at the fourth and fifth row center
seating positions. Do not secure a child seat in these
positions if a national or local law requires that the
top strap must be anchored.
If your child restraint does not have the LATCH system,
you'll be using the lap belt to secure the child restraint
in this position.
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.
