2020 LINCOLN AVIATOR brake

Note:
Certain add-on devices around the
bumper or fascia may create false alerts. For
example, large trailer hitches, bicycle or
surfboard racks, license plate brackets,
bumper covers or any other device that may
block the normal detection zone of the
system. Remove the add-on device to
prevent false alerts.
Note: The system does not react to small or
moving objects, particularly those close to
the ground.
Note: The system does not operate during
hard acceleration or steering.
Note: If your vehicle sustains damage to the
bumper or fascia leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts. Note:
Vehicle loading and suspension
changes can impact the angle of the sensors
and may change the normal detection zone
of the system resulting in inaccurate
measurement of obstacles or false alerts.
Note: When you connect a trailer, the system
may detect the trailer and provide an alert
or the system turns off. If the system does
not turn off, switch the system off manually
after you connect the trailer.
Note: You may experience reduced system
performance on road surfaces that limit
deceleration. For example, roads with ice,
loose gravel, mud or sand.

PRINCIPLE OF OPERATION
The traction control system helps avoid drive
wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels and,
when needed, reduces engine power at the
same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
USING TRACTION CONTROL
WARNING: The stability and traction
control light illuminates steadily if the
system detects a failure. Make sure you
did not manually disable the traction
control system using the information
display controls or the switch. If the stability
control and traction control light is still illuminating steadily, have the system
serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead to
an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
The system turns on each time you switch
on the ignition.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Note: When you switch traction control off,
stability control remains fully active.
Switching the System Off
When you switch the system off or on, a
message appears in the information display
showing system status.
You can switch the system off by accessing
the traction control settings through the
touchscreen.
See Settings (page 498). Note:
If your vehicle detects a loss of traction
due to excessive wheel spin or deceleration,
a display message appears on the
touchscreen prompting you to disable
traction control if needed.
Using the Information Display Controls
You can switch this feature off or on in the
information display.
See General
Information (page 130).
System Indicator Lights and Messages The stability and traction control
light:

PRINCIPLE OF OPERATION
WARNING: 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. WARNING:
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 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 systems applies higher
brake forces.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by applying
brakes to one or more of the wheels
individually and, if necessary, reducing
engine power.
246
Aviator (CTV) Canada/United States of America, enUSA, Edition date: 201902, Third-Printing- Stability Control

Roll Stability Control
The system enhances your vehicle
’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which it
changes by applying the brakes to one or
more wheels individually.
Curve Control
The system enhances your vehicle ’s ability
to follow the road when cornering severely
or avoiding objects in the roadway. Curve
Control operates by reducing engine power
and, if necessary, applying brakes to one or
more of the wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 245). Vehicle without stability control

WHAT IS HILL DESCENT CONTROL
WARNING: Hill descent control
cannot control descent in all surface
conditions and circumstances, such as ice
or extremely steep grades. Hill descent
control is a driver assist system and cannot
substitute for good judgment by the driver.
Failure to do so may result in loss of
vehicle control, crash or serious injury. WARNING:
The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake and shift the transmission into park
(P) for automatic transmission or first gear
for manual transmission.
Note: The system does not function below
3 mph (5 km/h)
.
Hill descent control allows the driver to set
and maintain vehicle speed while
descending steep slopes in various surface
conditions. The system can maintain vehicle speeds on
downhill slopes between
3–20 mph
(5–32 km/h). Above 20 mph (32 km/h), the
system remains on but the descent speed
cannot be set or maintained.
The system requires a cool down interval
after a period of sustained use. The amount
of time that the system can remain active
before cooling varies with conditions. The
system provides a warning in the message
center and a tone sounds when the system
is about to disengage for cooling. At this
time, manually apply the brakes as needed
to maintain descent speed.
SWITCHING HILL DESCENT
CONTROL ON AND OFF
You can switch the hill descent control on
and off through the touchscreen. SETTING THE HILL DESCENT
SPEED WARNING:
The system does not
replace the parking brake. When you leave
your vehicle, always apply the parking
brake and shift the transmission into park
(P) for automatic transmission or first gear
for manual transmission. WARNING:
The system does not
control speed in low traction conditions or
extremely steep slopes. 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 personal injury.
To increase the descent speed, press the
accelerator pedal until you reach the speed
you prefer.
To decrease the descent speed, press the
brake pedal until you reach the speed you
prefer.

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care and
attention. Failure to take care may result
in a crash. WARNING:
Traffic control systems,
inclement weather, air brakes, external
motors and fans may affect the correct
operation of the sensing system. This may
cause reduced performance or false alerts. WARNING:
The system may not
detect small or moving objects, particularly
those close to the ground.
Note: If your vehicle has MyKey™, the sensing
system cannot be switched off when a
MyKey™ is present.
See Principle of
Operation (page 73). Note:
Keep the sensors on the bumper or
fascia free from snow, ice and large
accumulations of dirt. If the sensors are
covered, the system’ s accuracy can be
affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the
bumper or fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alerts.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system. Remove the add-on device to
prevent false alerts.
Note: When you connect a trailer to your
vehicle, the rear parking aid may detect the
trailer and therefore provide an alert. Disable
the rear parking aid when you connect a
trailer to prevent the alert. The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
You can switch the system off through the
touchscreen, information display or from the
pop-up message that appears once you shift
the transmission into reverse (R). If your
vehicle has a parking aid button, you can
switch the system off by pressing the button.
If a fault is present in the system, a warning
message appears in the information display.

Note:
Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage
leaving the sensors misaligned, this may
cause inaccurate measurements or false
alerts.
Note: If you switch traction control off, the
side sensing system also turns off.
Note: Some accessories, for example large
trailer hitches or bike or surfboard racks can
cause reduced performance or false alerts.
Note: The system does not detect an object
that is moving toward the side of your
vehicle, for example another vehicle moving
at low speed, if it does not pass a front or
rear sensor.
The system uses the front and rear
outermost parking aid sensors to detect
objects that are near to the sides of your
vehicle. The system displays them on a
virtual map in the information display as your
vehicle moves past them.
The sensors are on the front and rear
bumpers. The system may not function if:
•
You switch the ignition on, off and back
on within a few seconds.
• Your vehicle remains stationary for over
two minutes.
• The anti-lock brake system activates.
• The traction control system activates.
To reinitialize the system, you may have to
drive your vehicle approximately 10 ft (3 m). The sensor coverage area is up to
24 in
(60 cm) from the side of your vehicle. When the system detects an object within
the coverage area and the driving path of
your vehicle, an audible warning sounds. As
the object moves closer to your vehicle, the
rate of the tone increases.
Object Distance Indicator
(If Equipped)
The system provides object distance
indication through the information display.
