Q:
What is wrong with this?
A:
The belt is twisted across the body.
1-22
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.
