2015 FORD FLEX cruise control

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 the system does not detect a vehicle
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. The system can only detect
these vehicles once they move 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. You should
stay alert and intervene when necessary.
If the front end of your 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.

Blocked Sensor
WARNING:Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly
when ACC is activated because the brakes are electronically controlled.
Failing to do so may result in loss of vehicle control, which could result
in serious injury.
WARNING:Do not use tires sizes other than those
recommended because this can affect the normal operation of
ACC. Failing to do so may result in a loss of vehicle control, which
could result in serious injury.
A message regarding a blocked
sensor is displayed if the radar
signals from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the
driver side of the lower grille. A
vehicle ahead cannot be detected
and the system will not function
when the radar signals are obstructed. The following table lists possible
causes and actions for this message being displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some way.Clean the grille surface in front of
the radar or remove the object
causing the obstruction.
The surface of the radar in the
grille is clean but the message
remains in the display.Wait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed.
Heavy rain or snow is interfering
with the radar signals.Do not use the system in these
conditions because it may not
detect any vehicle ahead.

Cause Action
Swirling water, or snow or ice on
the surface of the road may
interfere with the radar signals.Do not use system in these
conditions because it may not
detect any vehicle ahead.
You are in a desert or 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.
