FORD 2003 Expedition v.1 - Manual (Page 162)

The safety belt pretensioner removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and Safety Canopy
௢
system. When the safety belt pretensioner deploys, the lap and shoulder
belt are tightened.
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 seat 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 air bags or Safety Canopy
௢ and safety belt pretensioners.
Refer to the Safety belt maintenance section in this chapter.
Front and second row safety belt height adjustment
Your vehicle has safety belt height
adjustments for the driver, right
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 and slide the height
adjuster down. To raise the height
of the shoulder belt, push the
button 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.
