Ford Super Duty (2017 year). Manual — part 60

Each time you start the vehicle, the system
selects the last chosen gap for the current
driver.

Disengaging the System

Press the brake pedal or press CNCL. The
last set speed displays in grey but does not
erase.

Overriding the System

WARNING

If you override the system by pressing
the accelerator pedal, it does not
automatically apply the brakes to

maintain a gap from any vehicle ahead.

When you press the accelerator pedal, you
override the set speed and gap distance.

E144529

The green indicator illuminates
when the system engages.

The system resumes operation

when you release the accelerator pedal.
The vehicle speed decreases to the set
speed, or to a lower speed if following a
slower vehicle.

Changing the Set Speed

•

Accelerate or brake to the desired
speed, then press and release SET+.

•

Press and hold SET+ or SET- until the
desired set speed shows on the
information display. The vehicle speed
gradually changes to the selected
speed.

•

Press and release SET+ or SET-. The
set speed changes in approximately
1 mph (1 km/h).

•

Hold the SET+ or SET- button to
change the set speed in increments of
approximately 5 mph or 10 km/h.

The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display while the system is
active.

Resuming the Set Speed

Note: Only use resume if you are aware of
the set speed and intend to return to it.

Press and release RES. The vehicle returns
to the previously set speed. The set speed
shows continuously in the information
display while the system is active.

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 and Trailer Tow
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.

Note: When towing with adaptive cruise
control, turn on Tow/Haul Mode and Diesel
Engine Brake.

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.

(If Equipped)

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

WARNING

On rare occasions, detection issues
can occur due to the road
infrastructures, for example bridges,

tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required.

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.

244

(If Equipped)

If something hits the front end of your
vehicle or damage occurs, the
radar-sensing zone may change. This could
cause missed or false vehicle detections.
Contact an authorized dealer to have them
check for proper coverage and operation.

System Not Available

Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
•

A blocked sensor.

•

High brake temperature.

•

A failure in the system or a related
system.

Note: If you disable electronic stability
control, adaptive cruise control is not
available. See Using Stability Control
(page 227).

Blocked Sensor

E183741

A message displays if something obstructs
the radar signals from the sensor. The
sensor is behind a cover near the driver side
of the lower grille. The system cannot
detect a vehicle ahead and does not
function when something obstructs the
radar signals. The following table lists
possible causes and actions for this
message displaying.

Action

Cause

Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion.

The surface of the radar in the grille is dirty
or obstructed in some way.

Wait a short time. It may take several
minutes for the radar to detect that it is free
from obstruction.

The surface of the radar in the grille is clean
but the message remains in the display.

Do not use the system in these conditions
because it may not detect any vehicles
ahead.

Heavy rain or snow is interfering with the
radar signals.

Do not use the system in these conditions
because it may not detect any vehicles
ahead.

Swirling water, or snow or ice on the surface
of the road may interfere with the radar
signals.

Wait a short time or switch to normal cruise
control.

You are in a desert or remote area with no
other vehicles and no roadside objects.

245

(If Equipped)

Due to the nature of radar technology, it is
possible to get a blockage warning and not
have a blockage. This can happen, for
example, when driving in sparse rural or
desert environments. A false blocked
condition either self clears or clears after
a key cycle.

Switching to Normal Cruise
Control

WARNING

Normal cruise control will not brake
when your vehicle is approaching
slower vehicles. Always be aware of

which mode you have selected and apply
the brakes when necessary.

You can manually change from adaptive
cruise control to normal cruise control
through the information display. See
Information Messages (page 128).

E71340

The cruise control indicator light
replaces the adaptive cruise
control indicator light if you

select normal cruise control. The gap
setting does not display, the system does
not automatically respond to lead vehicles
and automatic braking remains active to
maintain set speed. The system recalls its
last setting when you start your vehicle.
