CHEVROLET 2010 Silverado - Manual (Page 71)

Q: What is wrong with this?
A: The belt is twisted across the body.
{ WARNING:
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/retailer to fix it.
