Chevrolet 2005 Uplander Owner's Manual page 51

CAUTION:
{
Newborn infants need complete support,
including support for the head and neck. This is
necessary because a newborn infant's neck is
weak and its head weighs so much compared
with the rest of its body. In a crash, an infant in a
rear-facing seat settles into the restraint, so the
crash forces can be distributed across the
strongest part of an infant's body, the back and
shoulders. Infants always should be secured in
appropriate infant restraints.
CAUTION:
{
The body structure of a young child is quite
unlike that of an adult or older child, for whom
the safety belts are designed. A young child's
hip bones are still so small that the vehicle's
regular safety belt may not remain low on the
hip bones, as it should. Instead, it may settle up
around the child's abdomen. In a crash, the belt
would apply force on a body area that is
unprotected by any bony structure. This alone
could cause serious or fatal injuries. Young
children always should be secured in
appropriate child restraints.
