FORD 2000 Windstar - Manual (Page 134)

Lap belts
Adjusting the lap belt
The lap belt does not adjust automatically.
The lap belts should fit snugly and as low as possible around the
hips, not around the waist.
Insert the tongue into the correct
buckle (the buckle closest to the
direction the tongue is coming
from). To lengthen the belt, turn the
tongue at a right angle to the belt
and pull across your lap until it
reaches the buckle. To tighten the
belt, pull the loose end of the belt
through the tongue until it fits
snugly across the hips.
Shorten and fasten the belt when
not in use.
