CAUTION:
{
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 in Rear Seat Passengers on
page 37. Make sure that the shoulder
belt crosses the shoulder.
To remove and store a comfort guide, squeeze
the belt edges together so that you can take them
out of the guide. Slide the guide back on its
storage clip located between the interior body
and the seatback.
