As a guide, if you are shorter than average, you will
prefer the shoulder belt anchorage in a lower position,
and if you are taller than average, you will prefer the
shoulder belt anchorage in a higher position. After you
release the anchorage button, try to move it up or down
to make sure that it is locked in position.
