A booster seat (F) is designed for children who 
are about 40 to 60 lbs., or even up to 80 lbs. 
(18 to 27 kg, or even up to 36 kg), and about four
to eight years of age. A booster seat is designed to
improve the fit of the vehicle’s safety belt system.

When choosing a 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. These restraints use the belt system in
your vehicle, but the child also has to be secured within
the restraint to help reduce the chance of personal injury.
The instructions that come with the child restraint will
show you how to do that. Both the owner’s manual and
the child restraint instructions are important, so if either
one of these is not available, obtain a replacement copy
from the manufacturer.

The child restraint must be secured properly in the
passenger seat.

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.
