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 safety belt locks if there is a sudden stop
or a crash.
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.
To unlatch the belt, just push the button on the
buckle. For outboard seating positions, when
the safety belt is not in use, slide the latch plate
up the safety belt webbing. The latch plate should
rest on the stitching on the safety belt, near the
guide loop on the side wall.
