Ford 2002 Excursion Owner's Manual page 145

The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to the Safety belt maintenance section in this
chapter.
Failure to replace the safety belt assembly under the above
conditions could result in severe personal injuries in the event of
a collision.
Front and second row safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver, front
passenger and second row outboard
passengers. Adjust the height of the
shoulder belt so the belt rests
across the middle of your shoulder.
To lower the shoulder belt height,
push the button down and slide the
height adjuster down. To raise the
height of the shoulder belt, slide the
height adjuster up. Pull down on the
height adjuster to make sure it is locked in place.
Position the shoulder belt height adjusters so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the seat belt and
increase the risk of injury in a collision.
