2-22 Seats and Restraints
3. The belt should not be twisted
and it should lie flat. The elastic
cord must be under the belt and
the guide on top.
WARNING
A safety belt that is not properly
worn may not provide the
protection needed in a crash.
The person wearing the belt could
be seriously injured. 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.
4. Buckle, position, and release
the safety belt as described
previously in this section. Make
sure that the shoulder belt
crosses the shoulder.
To remove and store the comfort
guide, squeeze the belt edges
together so that the safety belt can
be removed from the guide. Slide
the guide back into its storage
pocket located on the side of the
seatback.
