Pontiac 2005 Grand Prix - Manual (Page 36)

{ CAUTION:
Never do this.
Here two children are wearing the same belt.
The belt can not properly spread the impact
forces. In a crash, the two children can be
crushed together and seriously injured. A belt
must be used by only one person at a time.
Q:
What if a child is wearing a lap-shoulder belt,
but the child is so small that the shoulder belt
is very close to the child’s face or neck?
A:
If the child is sitting in a seat next to a window,
move the child toward the center of the vehicle.
If the child is sitting in the center rear seat position,
move the child toward the safety belt buckle. In
either case, be sure that the shoulder belt still is on
the child’s shoulder, so that in a crash the child’s
upper body would have the restraint that belts
provide. If the child is sitting in a rear seat outside
position, see Rear Safety Belt Comfort Guides
for Children and Small Adults on page 1-26
