Ford Windstar Owner's Manual page 190

The automatic locking mode must be used to hold small
children in position, particularly sleeping children and those
who may try to squirm out of the belts. The emergency locking
mode is also used while buckling the belts.
Frequently check the child seat's lap and shoulder harness belts
for correct placement and tightness. Use the child seat only if
the harness belts will stay snug when belts are placed into the
lock mode with a child in the seat. If belts do not remain snug,
take the vehicle to the dealer for child seat repair.
Always adjust the lap and shoulder harness belts provided with
this child seat snugly around your child.
Do not leave children, unreliable adults, or pets
unattended in your vehicle.
Safety belts and seats can become hot in a vehicle that
has been closed up in sunny weather; they could burn a
small child. Check seat covers and buckles before you
place a child anywhere near them.
Failure to follow all of the instructions on the use of this
child restraint system can result in your child striking the
vehicle's interior during a sudden stop or crash.
