FORD 2015 F-150 - Manual (Page 221)

Low Speed Automatic
Cancellation
The system does not function at vehicle
speeds below 12.4 mph (20 km/h). An
audible alarm sounds and the automatic
braking releases if the vehicle drops below
this speed.
Hilly Condition Usage
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again when the brakes have
cooled.
Select a lower gear when the system is
active in situations such as prolonged
downhill driving on steep grades, for
example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle’s regular brake system to prevent
it from overheating.
Switching the System Off
Note: The set speed memory erases when
you switch off the system.
Press and release OFF or switch off the
ignition.
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
does not illuminate if the system does not
detect a vehicle in front of you.
E71621
Detection issues can occur:
When driving on a different line
than the vehicle in front. A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane. B
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. C
In these cases the system may brake late
or unexpectedly. Stay alert and take action
when necessary.
