traction control LINCOLN AVIATOR 2020 User Guide

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.

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.

The system is unable to detect a vehicle, curb or object to park next to or in-between.
The system does not correctly operate.
You may have switched traction control off.
The system does not search for a parking space.
The transmission is in reverse (R). Your vehicle must be moving forward to be able to
detect a parking space.
The sensors may be blocked. For example, snow, ice or large accumulations of dirt.
Blocked sensors can affect how the system functions.
The system does not offer a parking space.
The sensors in the front or rear bumper could be damaged.
There is not enough room in the parking space for your vehicle to safely\
park.
There is not enough space for the parking maneuver on the opposite side \
of the parking
space.
The parking space is more than 5 ft (1.5 m) or less than 2 ft (0.5 m) away.
The vehicle speed is greater than 22 mph (35 km/h) for parallel parkin\
g or greater than
19 mph (30 km/h)
for perpendicular parking.
You recently disconnected or replaced the battery. After you reconnect the battery you
must drive your vehicle on a straight road for a short period of time.
An irregular curb along the parking space prevents the system from corre\
ctly aligning
your vehicle.
The system does not correctly position your vehicle
in a parking space.

WARNING: Pay close attention to
changing road conditions such as entering
or leaving a highway, on roads with
intersections or roundabouts, roads
without visible lanes of travel, roads that
are winding, slippery, unpaved, or steep
slopes. 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. WARNING:
The system is not a crash
warning or avoidance system. WARNING:
Do not use the system
when towing a trailer that has aftermarket
electronic trailer brake controls. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
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. WARNING:
Do not use the system
with a snow plow blade installed. WARNING:
Do not use the system in
poor visibility, for example fog, heavy rain,
spray or snow.
When 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. 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.

Detection issues can occur:
When driving on a different line
than the vehicle in front.
A B With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
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.
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.

WHAT IS DRIVE MODE CONTROL
The system delivers a driving experience
through a suite of sophisticated electronic
vehicle systems. These systems optimize
steering, handling and powertrain response.
This provides a single location to control
multiple systems performance settings.
Changing the drive mode automatically
changes the functionality of the following
systems:
•
Electronically power-assisted steering
system adjusts steering effort and feel
based on the mode you select. See
Steering (page 299).
• Electronic stability control and traction
control maintains your vehicle control in
adverse conditions or high performance
driving. See
Stability Control (page 246).
• Electronic throttle control enhances the
powertrain response to your driving
inputs.
• Transmission controls optimize with shift
schedules tuned to each mode.
• AWD settings become optimized and
tuned to each mode. The system automatically tailors your vehicle
configuration for each mode you select.
Note:
Not all settings, or modes, may be
available.
Note: The system has diagnostic checks that
continuously monitor the system for proper
operation. If a mode is unavailable due to a
system fault, the mode defaults to Normal.
SELECTING A DRIVE MODE
Note: Drive mode changes may not be
available when the ignition is off. Rotate the drive mode dial on the center
console to change the drive mode.
