Buick Lucerne 2007 Owner's Manual page 51

A booster seat (F-G) is a child restraint designed to
improve the fit of the vehicle's safety belt system.
Some booster seats have a shoulder belt
positioner, and some high-back booster seats
have a five-point harness. A booster seat can
also help a child to see out the window.
Q:
How Should I Use a Child Restraint?
A:
A child restraint system is any device designed
for use in a motor vehicle to restrain, seat,
or position children. A built-in child restraint
system is a permanent part of the motor
vehicle. An add-on child restraint system is
a portable one, which is purchased by the
vehicle's owner. To help reduce injuries, an
add-on child restraint must be secured in the
vehicle. With built-in or add-on child restraints,
the child has to be secured within the child
restraint.
When choosing an add-on child restraint,
be sure the child restraint is designed to be
used in a vehicle. If it is, it will have a label
saying that it meets federal motor vehicle safety
standards. Then follow the instructions for the
restraint. You may find these instructions on the
restraint itself or in a booklet, or both.
