brake LINCOLN NAUTILUS 2020 Repair Manual

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.
Note: The system remembers 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
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
driver door after you stop your vehicle.
• You hold your 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. 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:
240
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Cruise ControlE71621

•
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 WARNING: The system may not
operate properly if the sensor is blocked.
Keep the windshield free from obstruction. The camera is mounted behind the interior
mirror. The sensor is in the lower grille.
Note:
You cannot see the sensor. It is behind
a fascia panel.
A message displays if something obstructs
the camera or the sensor. The system cannot
detect a vehicle ahead and does not function
when something blocks the sensor.
241
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Cruise ControlE243054 E244279

Keep the front of your vehicle free of dirt,
metal badges or objects. Vehicle front
protectors and aftermarket lights may also
block the sensor.
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. 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.
Using Lane Centering WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
Do not use the system
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. WARNING:
Do not use the system
in poor visibility, for example fog, heavy
rain, spray or snow. WARNING: Large contrasts in outside
lighting can limit sensor performance. WARNING:
The sensor may
incorrectly track lane markings as other
structures or objects. This can result in a
false or missed warning. WARNING:
Do not use the system
when towing a trailer. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death.
The system is designed to help keep your
vehicle in the center of the lane by applying
continuous assistance steering torque input
toward the lane center on highways.
Note: The assistance steering torque is
limited and may not be sufficient for all
driving situations.

STEERING
Electric Power Steering
WARNING: The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked as soon as possible. WARNING:
If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required. If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to the
steering system. You do not lose the ability
to steer your vehicle manually. Typical
steering and driving maneuvers allow the
system to cool and return to normal
operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment. Note:
A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
(If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with the
brake system to help operate advanced
stability control and accident avoidance
systems. Additionally, whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short distance
before the system relearns the strategy and
reactivates all systems.

PRE-COLLISION ASSIST
WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Failure to take care may result in the loss
of control of your vehicle, serious personal
injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury. WARNING:
The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
In situations where the
vehicle camera has limited detection
capability, this may reduce system
performance. These situations include but
are not limited to direct or low sunlight,
vehicles at night without tail lights,
unconventional vehicle types, pedestrians
with complex backgrounds, running
pedestrians, partly obscured pedestrians,
or pedestrians that the system cannot
distinguish from a group. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death. WARNING:
The system cannot help
prevent all crashes. Do not rely on this
system to replace driver judgment and the
need to maintain a safe distance and
speed.
Using the Pre-Collision Assist System
The system is active at speeds above
approximately 3 mph (5 km/h) and pedestrian
detection is active at speeds up to
50 mph
(80 km/h). If your vehicle is rapidly approaching another
stationary vehicle, a vehicle traveling in the
same direction as yours, or a pedestrian
within your driving path, the system is
designed to provide three levels of
functionality:
1. Alert
2. Brake Support
3. Active Braking
261
Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 201907, First-Printing Driving AidsE156130

Alert: When active, a flashing visual warning
appears and an audible warning tone
sounds.
Brake Support
: The system is designed to
help reduce the impact speed by preparing
the brakes for rapid braking. Brake support
does not automatically apply the brakes. If
you press the brake pedal, the system could
apply additional braking up to maximum
braking force, even if you lightly press the
brake pedal. 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.
Note: Brake Support and Active Braking are
active at speeds up to 75 mph (120 km/h). If
the vehicle has a radar sensor, included with
Adaptive Cruise Control, then Brake Support
and Active Braking are active up to the
maximum speed of the vehicle.
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. Distance Indication and Alert (If Equipped)
Distance Indication and Alert is a function
that provides the driver with a graphical
indication of the time gap to other preceding
vehicles traveling in the same direction. The
Distance Indication and Alert screen in the
display screen shows one of the graphics
that follow.

WARNING: Exceeding the Safety
Compliance Certification label vehicle
weight limits can adversely affect the
performance and handling of your
vehicle, cause vehicle damage and
can result in the loss of control of your
vehicle, serious personal injury or
death.
Maximum Loaded Trailer Weight
Maximum loaded trailer weight is the
highest possible weight of a fully loaded
trailer the vehicle can tow. Consult an
authorized dealer (or the RV and Trailer
Towing Guide available at an authorized
dealer) for more detailed information.
GCWR (Gross Combined Weight
Rating)
GCWR is the maximum allowable weight
of the vehicle and the loaded trailer,
including all cargo and passengers, that
the vehicle can handle without risking
damage. (Important: The towing
vehicle ’s braking system is rated for operation at Gross Vehicle Weight
Rating, not at Gross Combined Weight
Rating.) Separate functional brakes
should be used for safe control of towed
vehicles and for trailers where the Gross
Combined Weight of the towing vehicle
plus the trailer exceed the Gross Vehicle
Weight Rating of the towing vehicle.
The gross combined weight must never
exceed the Gross Combined Weight
Rating.
Note:
For trailer towing information
refer to the RV and Trailer Towing Guide
available at an authorized dealer. WARNING:
Do not exceed the
GVWR or the GAWR specified on the
certification label. WARNING:
Do not use
replacement tires with lower load
carrying capacities than the original
tires because they may lower your
vehicle's GVWR and GAWR limitations.
Replacement tires with a higher limit
than the original tires do not increase
the GVWR and GAWR limitations. WARNING:
Exceeding any
vehicle weight rating can adversely
affect the performance and handling
of your vehicle, cause vehicle damage
and can result in the loss of control of
your vehicle, serious personal injury
or death.
Steps for determining the correct load
limit:
1. Locate the statement "The combined
weight of occupants and cargo
should never exceed XXX kg or XXX
lb." on your vehicle ’s placard.

TOWING A TRAILER
WARNING: Do not exceed the
GVWR or the GAWR specified on the
certification label. WARNING:
Towing trailers
beyond the maximum recommended
gross trailer weight exceeds the limit
of your vehicle and could result in
engine damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and personal
injury.
Note: Your vehicle may have electrical
items, such as fuses or relays, related
to towing.
See Fuses (page 303).
Your vehicle's load capacity designation
is by weight, not by volume, so you
cannot necessarily use all available
space when loading a vehicle or trailer. Towing a trailer places an extra load on
your vehicle's engine, transmission, axle,
brakes, tires and suspension. Inspect
these components periodically during,
and after, any towing operation.
Load Placement
To help minimize how trailer movement
affects your vehicle when driving:
•
Load the heaviest items closest to
the trailer floor.
• Load the heaviest items centered
between the left and right side trailer
tires. •
Load the heaviest items above the
trailer axles or just slightly forward
toward the trailer tongue. Do not
allow the final trailer tongue weight
to go above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the correct
rise or drop. When both the loaded
vehicle and trailer are connected, the
trailer frame should be level, or
slightly angled down toward your
vehicle, when viewed from the side.
When driving with a trailer or payload, a
slight takeoff vibration or shudder may
be present due to the increased payload
weight. Additional information regarding
proper trailer loading and setting your
vehicle up for towing is located in the
Load Carrying chapter. See Load Limit
(page 273).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.

TRAILER SWAY CONTROL WARNING: Turning off trailer sway
control increases the risk of loss of vehicle
control, serious injury or death. Ford does
not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple times,
gradually reducing vehicle speed. This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE SPEED
appears in the information display. The first
thing to do is slow your vehicle down, then
pull safely to the side of the road and check
for proper tongue load and trailer load
distribution.
See Load Carrying (page 270).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed the trailer weight
for your vehicle configuration listed in
the chart below. Note:
Make sure to take into
consideration trailer frontal area. Do not
exceed 20 ft² (1.86 m²) for vehicles
without towing package, or 30 ft² (2.79
m²) for vehicles with towing package.
Note: For high altitude operation,
reduce the gross combined weight by
2% per
1,000 ft (300 m) starting at the
1,000 ft (300 m) elevation point.
Note: Certain states require electric
trailer brakes for trailers over a specified
weight. Be sure to check state
regulations for this specified weight. The
maximum trailer weights listed may be
limited to this specified weight, as the
vehicle ’s electrical system may not
include the wiring connector needed to
activate electric trailer brakes.
