FORD 2013 Flex v.1 - Manual (Page 246)

Detection Issues
The radar sensor has a limited field of vision. It may not detect vehicles at
all or detect a vehicle later than expected in some situations. The lead
vehicle graphic will not illuminate if a vehicle is not detected in front of you.
Detection issues can occur:
A. When driving on a different line
than the vehicle in front.
B. With vehicles that edge into your
lane. These vehicles can only be
detected once they have moved fully
into your lane.
C. There may be issues with the
detection of vehicles in front when
driving into and coming out of a
bend or curve in the road.
In these cases the system may brake late or unexpectedly. The driver
should stay alert and intervene when necessary.
If the front end of the vehicle is hit or damaged, the radar sensing zone may
be altered causing missed or false vehicle detections. See your authorized
dealer to have the radar checked for proper coverage and operation.
Adaptive Cruise Control Not Available
Several conditions exist which can cause the system to deactivate or
prevent the system from activating when requested. These conditions
include:
• a blocked sensor
• high brake temperature
• a failure in the system or a related system.
