FORD 2013 Edge v.2 - Manual (Page 218)

Cause Action
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signals Do not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.
Desert / remote area with no other
vehicles and no roadside objects Wait a short time or switch to
normal cruise control.
Due to the nature of radar technology, it is possible to get a blockage
warning and not be blocked. This can happen, for example, when driving
in sparse rural or desert environments. A false blocked condition will
either self clear or clear after a key cycle.
Switching to Normal Cruise Control
WARNING: Normal cruise control will not brake due to slower
vehicles. Always be aware of which mode is selected and apply
the brakes when necessary.
You can manually change from adaptive cruise control to normal cruise
control through the information display.
The cruise control indicator light will replace the adaptive
cruise control indicator light if normal cruise control is selected.
The gap setting will not be displayed, the system will not
automatically respond to lead vehicles and automatic braking will not be
activated. The system will default to adaptive cruise control when the
engine is started.
