Pontiac 2010 Vibe - Manual (Page 33)

If you slid under it, the belt would
apply force on your abdomen.
This could cause serious or even
fatal injuries. The shoulder belt
should go over the shoulder and
across the chest. These parts of
the body are best able to take belt
restraining forces.
The shoulder belt locks if there is a
sudden stop or crash.
Q: What is wrong with this?
A: The shoulder belt is too loose.
It will not give as much
protection this way.
{ CAUTION
You can be seriously hurt if your
shoulder belt is too loose. In a
crash, you would move forward
too much, which could increase
injury. The shoulder belt should fit
snugly against your body.
