restraint for their weight and size.
We recommend that children be secured in a rear seat,
including: an infant or a child riding in a rear-facing child
restraint; a child riding in a forward-facing child seat; an
older child riding in a booster seat; and children, who
are large enough, using safety belts.
A label on the sun visor says, Never put a rear-facing
child seat in the front. This is because the risk to the
rear-facing child is so great, if the airbag deploys.
