Chevrolet 2007 Avalanche Owner's Manual page 47

CAUTION:
{
Never do this.
Here a child is sitting in a seat that has
a lap-shoulder belt, but the shoulder part
is behind the child. If the child wears
the belt in this way, in a crash the child
might slide under the belt. The belt's force
would then be applied right on the child's
abdomen. That could cause serious or
fatal injuries.
Wherever the child sits, the lap portion of the
belt should be worn low and snug on the hips,
just touching the child's thighs. This applies
belt force to the child's pelvic bones in a crash.
