Ford Expedition (2018 year). Manual — part 57

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.

E144529

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 RES+ or SET- to change the set
speed in small increments.

•

Press the accelerator or brake pedal
until you reach the desired speed. Press
RES+ or SET-.

•

Press and hold RES+ or SET- to
change the set speed in large
increments. Release the control when
you reach the desired 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 CNCL or tap the brake pedal. The
set speed does not erase.

Resuming the Set Speed

Note:

Only use resume if you are aware of

the set speed and intend to return to it.

Press RES+. 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.

Automatic Cancellation

Automatic cancellation can also occur if:
•

The tires lose traction.

•

You apply the parking brake.

Park Brake Application

Automatic parking brake application and
cancellation occurs if:
•

You unbuckle the seatbelt and open
the door after you stop the vehicle.

•

You hold the vehicle at a stop
continuously for more than three
minutes.

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 after the brakes cool.

Note:

When towing with adaptive cruise

control, turn on Tow/Haul Mode.

Note:

Tow/Haul mode increases the time

gaps and allows more distance for braking.

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 Adaptive Cruise Control
Off

Note:

You erase the set speed and gap

setting when you switch the system off.

Press OFF when the system is in standby
mode, or switch the ignition off.

Detection Issues

WARNINGS

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.

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.

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. 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.

System Not Available

The system may not turn on if there is:
•

A blocked sensor.

•

High brake temperature.

•

A failure in the system or a related
system.

Blocked Sensor

E257553

Note:

You cannot see the sensor. It is

behind a fascia panel.

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.

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.

Action

Cause

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. This happens, for example, when driving in sparse rural or desert
environments. 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.

You can change from adaptive cruise
control to normal cruise control through
the information display.

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, and the system
does not respond to lead vehicles.
Automatic braking remains active to
maintain set speed.
