FORD 2014 Taurus v.1 - Manual (Page 204)

With hands off the wheel (and nothing obstructing its movement) and
the transmission in R (Reverse), the vehicle steers itself as instructions
to safely move the vehicle back and forward in the space are displayed in
the touch screen. While reversing, the touch screen displays a message
instructing the driver to check their surroundings (for safety reasons)
and to back-up slowly, accompanied by a corresponding graphic.
When you think the vehicle has enough space in front and behind it, or
you hear a solid tone from the parking aid, bring the vehicle to a
complete stop.
When automatic steering is finished, the touch screen displays a message
indicating that the active park assist process is done. The driver is
responsible for checking the parking job and making any necessary
corrections before putting the transmission in P (Park).
