Switching the System On
Press and release ON.
The information display will
show the grey indicator light.
The current gap setting and
SET will
also display.
Setting a Speed
1. Accelerate to the desired speed.
2. Press and release
SET+. The
vehicle speed will be stored in the
memory.
3. The information display will show a green indicator light, current gap
setting and desired set speed.
4. Take your foot off the accelerator pedal. 5. A lead vehicle graphic will
illuminate if there is a vehicle
detected in front of you. Note:
When adaptive cruise control is
active, the set speed displayed in the
information display may vary slightly
from the speedometer.
Following a Vehicle WARNINGS
When following a vehicle in front
of you, your vehicle will not
decelerate automatically to a stop,
nor will your vehicle 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. Adaptive cruise control only
warns of vehicles detected by
the radar sensor. In some cases there
may be no warning or the warning
may be delayed. The driver should
always apply the brakes when
necessary. Failing to do so may result
in a crash, serious injury or death. Note:
The brakes may emit a sound
when modulated by the adaptive cruise
control system.
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. The distance setting is
adjustable.
The lead vehicle graphic will
illuminate.
212
MKZ (CC9) Cruise ControlE144529 E164805 E164805
The vehicle will maintain a constant
distance between 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 your lane or out of view
• the vehicle speed falls below 12
mph (20 km/h)
• a new gap distance is set.
The vehicle will apply the brakes to
slow the vehicle to maintain a safe
distance from the vehicle in front. The
maximum braking which the system
can apply is limited. You can override
the system by applying the brakes.
If the system predicts that its
maximum braking level will not be
sufficient, an audible warning will
sound while the system continues to
brake. This is accompanied by a
heads-up display; a red warning bar
illuminating on the windshield. You
should take immediate action.
Setting the Gap Distance
Note: It is your responsibility to select
a gap appropriate to the driving
conditions. Gap decrease

The last set speed will display in grey
but will not erase.
Overriding the System WARNING
Whenever the driver is overriding
the system by pressing the
accelerator pedal, the system will not
automatically apply the brakes to
maintain separation from any vehicle
ahead. You can override the set speed and
gap distance by pressing the
accelerator pedal. When you override the
system, the green indicator
light illuminates and the
lead vehicle graphic does not show in
the information display.
The system will resume operation
when you release the accelerator
pedal. The vehicle speed will decrease
to the set speed, or 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 will gradually change to the
selected speed.
• Press and release
SET+ or SET-.
The set speed will change in
approximately 1 mph (2 km/h)
increments.
The system may apply the brakes to
slow the vehicle to the new set speed.
The set speed will display
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
will return to the previously set speed.
The set speed will display
continuously in the information
display while the system is active.
Low Speed Automatic
Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). An
audible alarm will sound and the
automatic braking releases if the
vehicle drops below this speed. Hilly Condition Usage
Note:
An audible alarm will sound and
the system will shut down if it is
applying brakes for an extended period
of time. This allows the brakes to cool
down. The system will function
normally again when the brakes have
cooled down.
You should select a lower gear
position 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 them from overheating.
Switching the System Off
Note: The set speed memory erases
when you switch off the system.
Press and release
OFF or turn 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 will not illuminate if the
system does not detect a vehicle in
front of you.
215
MKZ (CC9) Cruise Control
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. The driver
should stay alert and intervene 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
detections. See an authorized dealer
to have the radar checked 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.
Blocked Sensor WARNINGS
Do not use the system when
towing a trailer with brake
controls. Aftermarket trailer brakes
will not function properly when the
system is activated because the
brakes are electronically controlled.
Failing to do so may result in loss of
vehicle control, which could result in
serious injury. Do not use tire sizes other than
those recommended because
this can affect the normal operation
of the system. Failing to do so may
result in a loss of vehicle control,
which could result in serious injury. 216

A message displays if something
obstructs the radar signals from the
sensor. The sensor is located behind
a fascia cover near the driver side of
the lower grille. The system cannot
detect a vehicle ahead and will 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 obstruction.
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 no longer obstructed.
The surface of the radar in the grille is
clean but the message remains in the display.
Do not use the system in these condi-tions 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 condi-tions 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 normalcruise 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
and not be blocked. This can happen,
for example, when driving in sparse
rural or desert environments. A false
blocked condition will either self clear
or clear after a key cycle. Switching to Normal Cruise
Control WARNING
Normal cruise control will not
brake due to slower vehicles.
Always be aware of which mode is
selected and apply the brakes when
necessary. 217

COLLISION WARNING
SYSTEM
PRINCIPLE OF OPERATION (If
Equipped) WARNINGS
This system is designed to be a
supplementary driving aid. It is
not intended to replace the driver ’s
attention, and judgment, or the need
to apply the brakes. This system does
NOT activate the brakes
automatically. Failure to press the
brake pedal to activate the brakes
may result in a collision. The collision warning system
with brake support cannot help
prevent all collisions. Do not rely on
this system to replace driver judgment
and the need to maintain distance
and speed. Note:
The system does not detect,
warn or respond to potential collisions
with vehicles to the rear or sides of the
vehicle.
Note: The collision warning system is
active at speeds above approximately
5 mph (8 km/h). This system is designed to alert the
driver of certain collision risks. A radar
detects if your vehicle is rapidly
approaching another vehicle traveling
in the same direction as yours. If it is, a red warning light illuminates
and an audible warning chime sounds.
The brake support system assists the
driver in reducing the collision speed
by charging the brakes. If the risk of
collision further increases after the
warning light illuminates, the brake
support prepares the brake system
for rapid braking. This may be
apparent to the driver. The system
does not automatically activate the
brakes but, if the brake pedal is
pressed, full force braking is applied
even if the brake pedal is lightly
pressed.
Using the Collision Warning
System
WARNING
The collision warning system
’s
brake support can only help
reduce the speed at which a collision
occurs if the driver applies the
vehicle ’s brakes. The brake pedal
must be pressed just like any typical
braking situation. 230

System Limitations WARNING
The collision warning system
’s
brake support can only help
reduce the speed at which a collision
occurs if the driver applies the
vehicle ’s brakes. The brake pedal
must be pressed just like any typical
braking situation. Due to the nature of radar technology,
there may be certain instances where
vehicles do not provide a collision
warning. These include: •
Stationary vehicles or vehicles
moving below 6 mph (10 km/h).
• Pedestrians or objects in the
roadway.
• Oncoming vehicles in the same
lane.
• Severe weather conditions (see
blocked sensor section).
• Debris build-up on the grille near
the headlamps (see blocked
sensor section).
• Small distance to vehicle ahead.
• Steering wheel and pedal
movements are large (very active
driving style).
