Top Strap
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, even though your
vehicle has reduced-force frontal air bags. 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-facing
child restraint 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 a rear seat.
Wherever you install it, be sure to secure the child
restraint properly.
Keep in mind that an unsecured child restraint can move
around in a collision or sudden stop and injure people in
the vehicle. Be sure to properly secure any child
restraint in your vehicle
--
even when no child is in it.
If your child restraint has a top strap, it should be
anchored. If you need to have an anchor installed, you
can ask your Buick dealer to put it in for you. If you
want to install an anchor yourself, your dealer can tell
you how to do it.
Canadian law requires that child restraints have a top
strap, and that the strap be anchored.
