Overriding the Set Speed 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. Use the accelerator pedal
normally to intentionally exceed
the set speed limit.
When you override the system, the green
indicator light illuminates and the vehicle
image does not appear in the information
display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a
lower speed if following a slower vehicle. Changing the Set Speed Press and release to increase the
set speed in small increments.
Press and release to decrease
the set speed in small
increments.
Press and hold either button to change the
set speed in large increments. Release the
button when you reach your preferred
speed.
The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.
Canceling the Set Speed Press and release the button or
tap the brake pedal.
The set speed does not erase.
Note: If you press the clutch pedal (manual
transmission only) for an extended period,
this action also cancels the set speed.
Resuming the Set Speed Press and release the button.
Your vehicle speed returns to the
previously set speed and gap setting. The
set speed displays continuously in the
information display when the system is
active.
Note: Only use resume if you are aware of
the set speed and intend to return to it.

Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). The
information display indicates low engine
speed, an audible alarm sounds and the
automatic braking releases if the vehicle
drops below this speed.
Automatic cancellation can also occur
when:
•
The tires lose traction.
• You apply the parking brake.
Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.
Hilly Condition and Trailer Tow
Usage
You should 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.
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 after the brakes cool.
Note: When towing with adaptive cruise
control, switch on Tow/Haul Mode and
Diesel Engine Brake.
Note: Tow/Haul mode increases the time
gaps and allows more distance for braking.
Switching Adaptive Cruise Control
Off Press and release the button
when the system is in standby
mode, or switch the ignition off. Note:
You erase the set speed and gap
setting when you switch the system off.
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. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.
The radar sensor has a limited field of view.
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.
247
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Cruise Control
(If Equipped)E265297

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. You should stay alert and
take action when necessary.
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 detection. Optimal system performance requires a
clear view of the road by the
windshield-mounted camera.
Optimal performance may not occur if:
•
The camera is blocked.
• There is poor visibility or lighting
conditions.
• There are bad weather conditions.
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.
Blocked Sensor The camera is mounted on the windshield
behind the interior mirror.

A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does
not function when something blocks the
sensor.
Note:
You cannot see the sensor. It is
behind a fascia panel.
Keep the front of your vehicle free of dirt,
metal badges or objects. Vehicle front
protectors and aftermarket lights may also
block the sensor.
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 is dirty or
obstructed.
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 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.
Water, 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.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. A false blocked condition either self clears, or clears after you restart your
vehicle.
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. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, and the system
does not respond to lead vehicles.
Automatic braking remains active to
maintain set speed.
You can change from adaptive cruise
control to normal cruise control through
the information display.

temporarily unable to provide a warning
on the indicated side(s). This may be
because:
• Your vehicle is under the activation
speed.
• The direction indicator is active.
• Your vehicle is in a dynamic maneuver.
• The road has no or poor lane markings
in the camera field-of-view.
• The camera is obscured or unable to
detect the lane markings due to
environmental, traffic or vehicle
conditions. For example, significant sun
angles, shadows, snow, heavy rain or
fog, following a large vehicle that is
blocking or shadowing the lane or poor

• Driving too close to the lane markings.
Troubleshooting Why is the feature not available (line markings are gray) when I can see the lane markings
on the road?
Your vehicle speed is outside the operational range of the feature.
The sun is shining directly into the camera lens.
A quick intentional lane change has occurred.
Your vehicle stays too close to the lane markings.
Driving at high speeds in curves.
The last feature activation occurred a short time ago.
Ambiguous lane markings, for example in construction zones.
Rapid transition from light to dark, or from dark to light.
Sudden offset in lane markings.
