FORD 2013 F-550 v.2 - Manual (Page 237)

Always use caution while reversing. Objects in the red zone are closest
to your vehicle and objects in the green zone are further away. Objects
are getting closer to your vehicle as they move from the green zone to
the yellow or red zones. Use the side view mirrors and rear view mirror
to get better coverage on both sides and rear of the vehicle.
Selectable settings for this feature are FIXED and OFF.
Visual Park Aid Alert
Note: Visual park alert is only available when the transmission is in
R (Reverse).
Note: The reverse sensing system is not effective at speeds above 3 mph
(5 km/h) and may not detect certain angular or moving objects.
The visual park aid alert allows the driver to view the area that is being
detected by the reverse sensing system. The system uses red, yellow and
green highlights which appear on top of the video image when an object
is detected by the reverse sensing system. The alert highlights the
closest object detected. The reverse sensing alert can be disabled and if
visual park aid alert is enabled, highlighted areas are still displayed.
Refer to Adjusting the Rear View Camera Settings above on how to
enable or disable the visual park alert feature.
