GMC 2009 Acadia - Manual (Page 26)

Q: What is wrong with this?
A: The belt is over an armrest.
{ CAUTION
You can be seriously injured if
your belt goes over an armrest
like this. The belt would be much
too high. In a crash, you can slide
under the belt. The belt force
would then be applied on the
abdomen, not on the pelvic
bones, and that could cause
serious or fatal injuries. Be sure
the belt goes under the armrests.
Q: What is wrong with this?
A: The shoulder belt is worn under
the arm. It should be worn over
the shoulder at all times.
