GMC YUKON DENALI 2000 Manual page 29

Q:
What's wrong with this?
A:
The shoulder belt is too loose. It won't give nearly
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 against your body.
