Securing Child Restraints
(Rear Center Seating
Position)
Many child restraints are too wide to
be correctly secured in the center
rear seat, although some of them
will fit there. If the center seat
position is too narrow for the child
restraint, secure it in a rear outside
seat position.
If a child restraint is secured in the
center seat position, follow the
instructions in Securing Child
Restraints (Rear Outboard Seating
Position)
on page 3‑59or Securing
Child Restraints (Rear Center
Seating Position)
on page 3‑61or

Front Seat Position) on page 3‑62.
