Seating and Safety Restraints
Follow all instructions provided by the
manufacturer of the booster seat.
Never put the shoulder belt under a child's
arm or behind the back because it
eliminates the protection for the upper part of the
body and may increase the risk of injury or death
in a collision.
Never use pillows, books, or towels to boost
a child. They can slide around and increase
the likelihood of injury or death in a collision.
SAFETY SEATS FOR CHILDREN
Child and infant or child safety seats
Use a safety seat that is recommended for the size
and weight of the child. Carefully follow all of the
manufacturer's instructions with the safety seat you
put in your vehicle. If you do not install and use the
safety seat properly, the child may be injured in a
sudden stop or collision.
When installing a child safety seat:
