traction control LINCOLN NAVIGATOR 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 automatically turns on each time
you switch the ignition on.
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 On and Off
You can switch traction control on and off
through the information display controls. See
General Information
(page 133).
When you switch the system off, a message
and an illuminated icon appear on the
instrument cluster.
Switch traction control on again to return the
system to normal operations. Note:
Your vehicle may have MyKey
restrictions regarding this feature.
See
Principle of Operation (page 78).
System Indicator Lights and Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:
• When a driving condition activates either
of the systems.
• If a problem occurs in either of the
systems. The stability and traction control
off light temporarily illuminates on
engine start-up and stays on when
you switch the traction control system off.

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 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:
244
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Stability Control

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.
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.
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 243). Vehicle without stability control

SIDE 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:
The system may not
detect small or moving objects, particularly
those close to the ground. WARNING:
To help avoid personal
injury, always use caution when in reverse
(R) and when using the sensing system. WARNING:
The parking aid system
can only assist you to detect objects when
your vehicle is moving at parking speeds.
To help avoid personal injury you must
take care when using the parking aid
system.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover up the sensors. 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.

Note:
If you drive your vehicle less than 2 ft
(0.5 m) or greater than 5 ft (1.5 m) away from
other parked vehicles, the system may not
be able to detect an available parking
space.
When the system detects a suitable space,
a message displays and a tone sounds. Stop
your vehicle and follow the onscreen
instructions. If your vehicle is moving very
slowly, you may have to move forward a
short distance before the system is ready to
park.
Note: You must observe that the space the
system selects remains clear of obstructions
at all times during the maneuver.
Note: The system always offers the last
parking space it detects. For example, if your
vehicle detects multiple spaces when you
are driving, it offers the last one.
Note: If the vehicle speed is greater than
approximately 22 mph (35 km/h), the system
shows a message to instruct you to reduce
the vehicle speed. Automatically Steering into a Parallel
Parking Space
When you shift into reverse (R), with your
hands off the steering wheel and nothing
obstructing its movement, your vehicle steers
itself into the space. The system displays
instructions to move your vehicle backward
and forward in the space.
Note:
If the vehicle speed exceeds
approximately
6 mph (9 km/h), you interrupt
the maneuver, or the system switches off,
you must take full control of your vehicle.
Note: If the system detects an object is very
close to your vehicle and it may be unsafe
to continue the maneuver, it may instruct you
to stop your vehicle. The system may not
provide any further instruction. Steering
assistance continues to operate but you
must decide if it is safe to continue the
maneuver. When you believe your vehicle is correctly
parked, or a solid tone sounds and an
information message appears, bring your
vehicle to a complete stop.
When the Active Park Assist maneuver is
complete, a tone sounds and an information
message appears.
Note:
You are responsible for checking how
your vehicle is parked and making any
necessary corrections before leaving your
vehicle.

parking spaces and steers your vehicle into
the space. You control the accelerator,
gearshift and brakes. The system visually
and audibly guides you into a perpendicular
parking space. Press the button twice to search
for a parking space. When the vehicle speed is less than 19 mph
(30 km/h), the system scans both sides of
your vehicle for an available parking space.
A message and a graphic appear in the
information display to indicate the system is
searching for a parking space. Use the
direction indicator lever to search for a
parking space on the driver or passenger
side of your vehicle.
Note: The system scans both sides of your
vehicle and offers parking spaces one side
at a time if you do not use the direction
indicator.
Note: The system defaults to the passenger
side if you do not use the direction indicator. Drive your vehicle approximately
3 ft (1 m)
and perpendicular to the other parked
vehicles when searching for a parking space. Note:
If you drive your vehicle less than 2 ft
(0.5 m)
or greater than 5 ft (1.5 m) away from
other parked vehicles, the system may not
be able to detect an available parking
space.
When the system detects a suitable space,
a message displays and a tone sounds. Stop
your vehicle and follow the onscreen

Troubleshooting
Possible Cause
Symptom
You may have switched the 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 dirt buildup. Blocked sensors
can affect how the system functions.
The system does not offer a parking space.
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.
Your vehicle is rolling in the opposite direction of the current transmis\
sion position. For
example, rolling forward when in reverse (R).
The system does not correctly position your vehicle
in a parking space.
An irregular curb along the parking space prevents the system from corre\
ctly aligning
your vehicle.

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.
The set speed does not erase.
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
door after you stop the vehicle.
• You hold the 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 and gap
setting 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.

Note:
If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor automatically recalibrates
successfully.
