Ford Mercury Villager 1997 Owner's Manual page 139

NOTE: The second row two-passenger bench seat has a unique
safety restraint system. If your vehicle has the
two-passenger bench seat it is very important that the
unique safety belt system is used properly. Please read
Auxiliary safety restraint system for the second row
bench seat in this section, which explains the unique
safety belt system. Be sure that you understand it before
anyone rides in the two-passenger bench seat.
Passenger Outboard Lap/Shoulder Belts
All seats except the driver's seat and the third seat middle
position are equipped with a dual locking mode retractor on the
shoulder belt portion of the lap/shoulder safety belt. (The
driver seat has only a vehicle sensitive locking mode and the
third seat middle position has a lap belt without a retractor —
description follows.)
Dual Locking Mode Retractors Operate in Two Ways:
Vehicle sensitive (emergency) locking mode
In this operating mode, the shoulder belt retractor will allow the
occupant freedom of movement, locking tight only on hard
braking, hard cornering or impacts of approximately 5 mph
(8 km/h) or more.
