FORD 2008 Expedition v.1 - Manual (Page 195)

When the Safety Canopy™ system and/or the front airbags are activated,
the safety belt pretensioners for the driver and right front passenger
seating positions will be activated when the respective seatbelt is
properly buckled.
The driver and the right front passenger safety belt system
(including retractors, buckles and height adjusters) must be
replaced if the vehicle is involved in a collision that results in
deployment of front airbags or Safety Canopy™ and safety belt
pretensioners.
Refer to the Safety belt maintenance section in this chapter.
Safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver and right
front passenger. Adjust the height of
the shoulder belt so the belt rests
across the middle of your shoulder.
To lower the shoulder belt height,
squeeze the side release buttons
with your thumb and finger and
slide the height adjuster down. To
raise the height of the shoulder belt,
squeeze the side release buttons
and slide the height adjuster up. Pull down on the height adjuster to
make sure it is locked in place.
Position the safety 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.
