Adjustable Upper Shoulder Belt Anchorage
In the front seating positions, the shoulder belt can be
adjusted upward or downward to position the belt away
from your neck. Press the release button to release the
anchorage, and then move it up or down to the position
that fits you best.
As a guide, if you are shorter than average, you will
prefer a lower position, and if you are taller than average,
you will prefer a higher position. When you release the
button, verify the shoulder belt anchorage is latched by
pulling downward on the shoulder belt anchorage until it
is locked into position.
