WARNING: Never place, or allow a child to place, the shoulder
belt under a child's arm or behind the back because it reduces
the protection for the upper part of the body and may increase the risk
of injury or death in a crash.
WARNING: To avoid risk of injury, do not leave children or pets
unattended in your vehicle.
