sensor FORD EXPEDITION 2019 Service Manual

The indicator, current gap setting and set
speed appear in the information display.
Following a Vehicle
WARNING: When following a
vehicle, your vehicle does not always
decelerate quickly enough to avoid a
crash without driver intervention. Always
apply the brakes when necessary. Failing
to do so may result in a crash, serious
injury or death. WARNING: Adaptive cruise control
only warns of vehicles detected by the
radar sensor. In some cases there may
be no warning or a delayed warning. You
should always apply the brakes when
necessary. Failure to do so may result in
a crash, serious injury or death.
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in
the same lane, the vehicle speed adjusts
to maintain a preset gap distance. A
vehicle graphic illuminates in the
instrument cluster.
Note: The brakes may emit noise when
applied by the system.
Note: When you are following a vehicle and
you switch on a direction indicator, adaptive
cruise control may provide a small
temporary acceleration to help you pass.
Your vehicle maintains a consistent gap
from the vehicle ahead until:
• The vehicle in front of you accelerates
to a speed above the set speed.
• The vehicle in front of you moves out
of the lane you are in.
• You set a new gap distance. The system applies the brakes to slow your
vehicle to maintain a safe gap distance
from the vehicle in front. The system only
applies limited braking. You can override
the system by applying the brakes.
If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds, a message appears in the
information display and an indicator
flashes when the system continues to
brake. Take immediate action.
Following a Vehicle to a Complete
Stop
If your vehicle follows a vehicle to a
complete stop and remains stationary for
less than three seconds, your vehicle
accelerates from a stationary position to
follow the vehicle ahead.
If your vehicle follows a vehicle
to a complete stop and remains
stationary for more than three
seconds, press to follow the vehicle ahead.
Or press the accelerator pedal.
Setting the Gap Distance
You can decrease or increase the distance
between your vehicle and the vehicle in
front by pressing the gap control. Press and release to decrease
the gap distance.
Press and release to increase the
gap distance.

Automatic Cancellation
Automatic cancellation can also occur
when:
•
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 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.
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 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.

Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-Printing Cruise ControlE265297

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 247
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201808, Second-Printing Cruise ControlE71621 E257553

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.
