If your vehicle is not a convertible, two top strap anchors
are already installed for the rear seating positions. You'll
find the anchors behind the rear seat, on the floor in the
cargo area.
Anchor the top strap to this bracket. Once you have the
top strap anchored, you'll be ready to secure the child
restraint itself.

Securing a Child Restraint in a Rear
Seat Position
-
You'll be using the lap shoulder belt. See the earlier
part about the top strap if the child restraint has one.
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.
1. Put the restraint on the seat.
2. Pick up the latch plate, and run the lap and shoulder
portions of the vehicle's safety belt through or
around the restraint. The child restraint instructions
will show you how.
