Anchor the top strap to one of these anchor points. Be
sure to use an anchor point located on the same side of
the vehicle as the seating position where the child
restraint will be placed.
Once you have the top strap anchored, you'll be ready to
secure the child restraint itself. Tighten the top strap
when and as the child restraint manufacturer's
instructions say.

Securing a Child Restraint in a
Rear Seat Position
CAUTION:
A child in a child restraint in the center front seat
can be badly injured or killed by the right front
passenger air bag if it inflates. Never secure a
child restraint in the center front seat. It's always
better to secure a child restraint in the rear seat.
You may secure a forward
in the right front passenger seat, but before you
do, always move the front passenger seat as far
back as it will go. It's better to secure the child
restraint in the rear seat.
