Cadillac 2006 STS - Manual (Page 25)

Q:
What is wrong with this?
A:
The belt is twisted across the body.
{ CAUTION:
You can be seriously injured by a twisted belt.
In a crash, you would not have the full width
of the belt to spread impact forces. If a belt
is twisted, make it straight so it can work
properly, or ask your dealer to fix it.
To unlatch the belt, just push the button on the buckle.
When the seatbelt is unbuckled or when the vehicle
is turned off, the tension reducer will deactivate.
The belt should go back out of the way.
