2020 LINCOLN NAUTILUS brake sensor

Following a Vehicle
WARNING: When following a vehicle
that is braking, your vehicle does not
always decelerate quickly enough to avoid
a crash without driver intervention. Apply
the brakes when necessary. Failure to
follow this instruction could result in
personal injury or death. WARNING: The system only warns
of vehicles detected by the radar sensor.
In some cases there may be no warning
or a delayed warning. Apply the brakes
when necessary. Failure to follow this
instruction could result in personal 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 and release the button 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 the button to
cycle through the four gap settings.

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:

•
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.

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.

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.

When Inflating Your Tires
WARNING: Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure to
follow this instruction could result in
personal injury or death.
When putting air into your tires (such as at a
gas station or in your garage), the tire
pressure monitoring system may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over
20 mph (32 km/h) for the light to turn off after
you have filled your tires to the
recommended inflation pressure.
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system monitors
tire pressure in each pneumatic tire. While
driving in a normal manner, a typical
passenger tire inflation pressure may
increase about
2–4 psi (14–28 kPa) from a
cold start situation. If the vehicle is stationary
overnight with the outside temperature significantly lower than the daytime
temperature, the tire pressure may decrease
about
3 psi (21 kPa) for a drop of 30°F (17°C)
in ambient temperature. This lower pressure
value may be detected by the tire pressure
monitoring system as being significantly
lower than the recommended inflation
pressure and activate the system warning
light for low tire pressure. If the low tire
pressure warning light is on, visually check
each tire to verify that no tire is flat. If one or
more tires are flat, repair as necessary.
Check the air pressure in the road tires. If
any tire is under-inflated, carefully drive the
vehicle to the nearest location where air can
be added to the tires. Inflate all the tires to
the recommended inflation pressure.
CHANGING A ROAD WHEEL WARNING:
If the tire pressure
monitor sensor becomes damaged it may
not function. Note:
The use of tire sealant may damage
your tire pressure monitoring system and
should only be used in roadside
emergencies. If you must use a sealant, use
the Tire Mobility Kit sealant. Replace the tire
pressure monitoring system sensor and
valve stem on the wheel by an authorized
dealer after use of the sealant.
Note: The tire pressure monitoring system
indicator light will illuminate when the spare
tire is in use. To restore the full function of
the monitoring system, all road wheels
equipped with tire pressure monitoring
sensors must be mounted on the vehicle.
If you get a flat tire while driving, do not apply
the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe place
on the side of the road.
