2017 LINCOLN MKX brake sensor

When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows time to move your foot
from the brake to the accelerator pedal. The
system releases the brakes automatically
once the engine has developed sufficient
torque to prevent your vehicle from rolling
down the slope. This is an advantage when
pulling away on a slope, for example from a
car park ramp, traffic lights or when reversing
uphill into a parking space.
Note:
The system only functions when you
bring your vehicle to a complete standstill in
an uphill gear (for example, drive (D) when
facing uphill or reverse (R) when facing
downhill).
Note: There is no warning light to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep the
brake pedal pressed. 2. If the sensors detect that your vehicle is
on a slope, the system activates
automatically.
3. When you remove your foot from the brake pedal, your vehicle remains on the
slope without rolling away for about two
to three seconds. This hold time
automatically extends if you are in the
process of driving off.
4. Drive off in the normal manner. The system releases the brakes automatically.
Note: When you remove your foot from the
brake pedal and press the pedal again when
the system is active, you will experience
significantly reduced brake pedal travel. This
is normal.
Switching the System On and Off
Vehicles with Manual Transmission
You can switch this feature on or off in the
information display. The system remembers
the last setting when you start your vehicle. Vehicles with Automatic Transmission
You cannot turn the system on or off. When
you switch the ignition on, the system
automatically turns on.
AUTO HOLD WARNINGS
The system does not replace the
parking brake. When you leave your
vehicle, always apply the parking brake. You must remain in your vehicle when
the system turns on. At all times, you
are responsible for controlling your vehicle,
supervising the system and intervening, if
required. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death. The system will turn off if a malfunction
is apparent. Failure to take care may
result in the loss of control of your vehicle,
serious personal injury or death. 199

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving braking
system, aftermarket roof racks,
suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability control
system. In addition, installing any stereo
loudspeakers may interfere with and
adversely affect the electronic stability
control system. Install any aftermarket stereo
loudspeaker as far as possible from the front
center console, the tunnel, and the front
seats in order to minimize the risk of
interfering with the electronic stability control
sensors. Reducing the effectiveness of the
electronic stability control system could lead
to an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. WARNINGS
Remember that even advanced
technology cannot defy the laws of
physics. It’ s always possible to lose control
of a vehicle due to inappropriate driver input
for the conditions. Aggressive driving on any
road condition can cause you to lose control
of your vehicle increasing the risk of personal
injury or property damage. Activation of the
electronic stability control system is an
indication that at least some of the tires have
exceeded their ability to grip the road; this
could reduce the operator’ s ability to control
the vehicle potentially resulting in a loss of
vehicle control, vehicle rollover, personal
injury and death. If your electronic stability
control system activates, SLOW DOWN. The system automatically turns on each time
you switch the ignition on.
If a fault occurs in either the stability control
or the traction control system, you may
experience the following conditions:•
The stability and traction control light
illuminates steadily.
• The stability control and traction control
systems do not enhance your vehicle's
ability to maintain traction of the wheels.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the system applies higher
brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:

WARNINGS
The sensors may not detect objects in
heavy rain or other conditions that
cause interference. Active park assist does not apply the
brakes under any circumstances.
The system is designed to aid the
driver. It is not intended to replace your
attention and judgment. You are still
responsible to drive with due care and
attention. Note:
The Blind Spot Information System
does not detect traffic alongside or behind
your vehicle during an active park assist
maneuver.
The system detects an available parallel or
perpendicular parking space and
automatically steers your vehicle into the
space (hands-free) while you control the
accelerator, gearshift and brakes. The system
visually and audibly guides you to park your
vehicle. If you are uncomfortable with the proximity
to any vehicle or object, you may choose to
override the system by grabbing the steering
wheel or pushing the active park assist
button.
Parallel Park Out Assist automatically steers
your vehicle out of a parallel parking space
(hands-free) while you control the
accelerator, gearshift and brakes. The system
visually and audibly guides you to enter
traffic.
The system may not correctly operate in any
of the following conditions:
•
You use a spare tire or a tire significantly
worn more than the other tires.
• One or more tires are improperly inflated.
• You try to park on a tight curve.
• Something passes between the front
bumper and the parking space (a
pedestrian or cyclist). •
The edge of the neighboring parked
vehicle is high off the ground (for
example, a bus, tow truck or flatbed
truck).
• The weather conditions are poor (heavy
rain, snow, fog, etc).
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. Covered sensors
can affect the system's accuracy. Do not
clean the sensors with sharp objects.
Note: The sensors may not detect objects
with surfaces that absorb ultrasonic waves
or cause ultrasonic interference (motorcycle
exhaust, truck air brakes or horns).
Do not use the system if:
• You have attached a foreign object (for
example, a bike rack or trailer) close to
the sensors on the front or rear of your
vehicle.
• You have attached an overhanging
object (for example, a surfboard) to the
roof.

USING ADAPTIVE CRUISE
CONTROL
(If Equipped) WARNINGS
Always pay close attention to changing
road conditions when using adaptive
cruise control. The system does not replace
attentive driving. Failing to pay attention to
the road may result in a crash, serious injury
or death. WARNINGS
Adaptive cruise control may not detect
stationary or slow moving vehicles
below
6 mph (10 km/h). Do not use the adaptive cruise control
when entering or leaving a highway,
on roads with intersections or roundabouts
or non-vehicular traffic or roads that are
winding, slippery, unpaved, or steep slopes. Do not use adaptive cruise control
when towing a trailer that has trailer
brakes. The auto-brake component of the
adaptive cruise control system does not
operate the trailer brakes. Using adaptive
cruise control when towing a trailer that has
trailer brakes may result in the loss of vehicle
control, which could result in serious injury. Adaptive cruise control is not a crash
warning or avoidance system.
Adaptive cruise control does not detect
pedestrians or objects in the road.
Adaptive cruise control does not detect
oncoming vehicles in the same lane. WARNINGS
Do not use the system in poor visibility,
for example fog, heavy rain, spray or
snow. Do not use tire sizes other than those
recommended because this can affect
the normal operation of the system. Failure
to do so may result in a loss of vehicle
control, which could result in serious injury. Note:
It is your responsibility to stay alert,
drive safely and be in control of the vehicle
at all times.
The system helps you to maintain a gap from
the vehicle in front of you. If there is no
vehicle in front of you the system will
maintain a set speed. The system is intended
to provide enhanced operation of your
vehicle when following other vehicles which
are in the same lane and traveling in the
same direction. You can select four gap
settings.
The system uses a radar sensor which
projects a beam directly in front of your
vehicle.

MKX (CD9) Canada/United States of America, enUSA, First Printing Cruise Control

WARNINGS
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. Note:
The brakes may emit noise when
applied by the 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. A vehicle
graphic illuminates in the instrument cluster.
When you are following a vehicle and you
switch on your left directional 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. •
The vehicle speed falls below 12 mph
(20 km/h).
• You set a new gap distance.
The vehicle applies 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 is insufficient, an audible
warning sounds while the system continues
to brake. The red warning bar appears on
the windshield. You should take immediate
action.
Setting the Gap Distance
You can decrease or increase the distance
between your vehicle and the vehicle in front
by pressing the gap control.
Note: It is your responsibility to select a gap
appropriate to the driving conditions. Gap decrease.
A
Gap increase.
B The selected gap appears in the information
display as shown by the bars in the graphic.
Four gap distance settings are available.

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. 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 A message appears if something obstructs
the sensor's radar signals. The sensor is
located 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 signal.
Note:
You cannot see the sensor, it is behind
a fascia panel.
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 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.

Brake Support: The brake support system
assists the driver in reducing the collision
speed by lightly applying 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 you press the brake pedal, the
system may apply full force, even if the brake
pedal is lightly pressed.
Active Braking
: Active braking may activate
if the system determines that a collision is
imminent. The system may help the driver
reduce impact damage or avoid the crash
completely.
Some vehicles are able to switch active
braking off using the information display
controls.
See General Information (page
114). Active braking automatically turns on
every time you switch the ignition on. Note:
If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends using
the highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings.
Adjusting the Pre-Collision Assist Settings
You can adjust the Pre-Collision Assist
settings by using the information display
control. See General Information (page 114).
If required, you can switch active braking off
using the information display control.
See
General Information (page 114).
Note: Active braking automatically turns on
every time you switch the ignition on. Blocked Sensors
