FORD 1999 Windstar - Manual (Page 137)

Contact the manufacturer of your child safety seat for information about
ordering a tether strap.
Tether anchorage hardware
Children should be placed in the rear in an appropriate child
safety seat that is properly secured to the vehicle.
Rear-facing infant seats must always be secured in the rear seat.
In vehicles without a rear seat, a rear-facing infant seat should
be secured in the front seat only if your vehicle does not have a
passenger side air bag or your vehicle is equipped with a passenger air
bag deactivate switch and the switch is turned to “OFF.”
When using forward-facing child safety seats in vehicles with
only two seating positions so the forward-facing child safety seat
cannot be placed in the rear of the vehicle, move the passenger seat as
far back from the instrument panel as possible.
Tether strap anchorage locations
have been provided in your vehicle.
The left side of the figure is the
front of the vehicle.
The tether can be attached directly to the rear of all passenger seating
except the front passenger seat equipped with power adjustment. The
front passenger seat with manual adjustment does have a tether anchor.
