2021 LINCOLN NAVIGATOR power steering

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings could be worn-out, you should
have them checked. If the vehicle has
continuous vibration or shudder in the
steering wheel while braking, you should
have the system checked.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Wheels
(page 403). See
Warning Lamps and
Indicators (page 129).
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when driving from a car wash or
standing water to dry the brakes. Brake Over Accelerator
In the event the accelerator pedal becomes
stuck or entrapped, apply steady and firm
pressure to the brake pedal to slow the
vehicle and reduce engine power. If you
experience this condition, apply the brakes
and bring your vehicle to a safe stop. Switch
the engine off, move the transmission to park
(P) and apply the parking brake. Inspect the
accelerator pedal and the area around it for
any items or debris that may be obstructing
its movement. If none are found and the
condition persists, do not drive your vehicle.
Have your vehicle towed to the location you
are having it checked.
Emergency Brake Assist
Emergency brake assist detects when you
brake heavily by measuring the rate at which
you press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal. Emergency brake assist
can reduce stopping distances in critical
situations.Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking. This lamp momentarily illuminates
when you switch the ignition on.
If the light does not illuminate
during start up, remains on or flashes, the
anti-lock braking system may be disabled.
Have the system checked. If the anti-lock
brake system is disabled, normal braking is
still effective. If the brake warning lamp
illuminates with the parking brake
released, have your brake system
serviced immediately.
It also illuminates momentarily when you
switch the ignition on to confirm the lamp is
functional. If it does not illuminate when you
switch the ignition on, or begins to flash at
any time, have the system checked.

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:

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.

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.
DRIVE MODE CONTROL
Lincoln Drive Modes
Lincoln Drive Modes deliver a driving
experience through a suite of sophisticated
electronic vehicle systems. These systems
optimize steering, handling and powertrain
response. You can control performance
settings for multiple systems from this single
location.
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 297).
• Electronic stability control and traction
control maintain your vehicle control in
adverse conditions or high performance
driving. See Stability Control (page 248).
• Electronic throttle control enhances the
powertrain response to your inputs.
• Transmission controls optimize with shift
schedules tuned to each mode.
• Driveline settings optimize for each
mode.
Using the System
The system automatically tailors your vehicle
configuration for each mode you select. To change the drive mode setting, use the
drive mode selector on the center console.
Note:
Mode changes are not available when
the vehicle ignition is off or when the engine
is not running.
Note: Not all settings may be available.

•
NORMAL – For everyday driving. This
mode is a perfect balance of excitement,
comfort and convenience.
• EXCITE – For aggressive on-road driving.
This mode increases throttle response,
provides a sportier steering feel, along
with quicker shifting. The suspension
stiffens, with an emphasis on handling
and control. The transmission also holds
gears longer, helping your vehicle
accelerate faster when shifting gears.
• CONSERVE
– Enables efficient and
responsible driving. It helps deliver
maximum fuel efficiency and increases
driving range.
• NORMAL 4A
– For general on-road
driving. Use this mode on normal firm
surfaces such as dry or wet pavement
and hard packed dirt or gravel roads.
Delivers power to all four wheels, as
required. •
SLIPPERY
– For less than ideal road
conditions, such as snow or ice covered
roads. Slippery mode inspires confidence
without taking away from driving
pleasure. Slippery mode lowers throttle
response and optimizes shifting for
slippery surfaces.
• DEEP CONDITIONS
– Used for crossing
terrain that has deformable deep, rutted
surfaces such as mud, deep snow or
deep sand. Do not use on dry, hard
surfaced roads.
• SLOW CLIMB
– Used when you need
extra power, such as when climbing
steep grades, going through deep sand
or pulling a boat out of a launch ramp.
Do not use on dry, hard surfaced roads.
Slow Climb mode puts you in 4x4 Low
drive line settings.
Note: Slow Climb is only available on
vehicles with 4x4 and a two-speed transfer
case. Note:
The system has diagnostic checks that
continuously monitor the system for proper
operation. Certain drive modes are not
available based on gear shifter position. If
a mode is unavailable due to a system fault
or change in gear shifter position, the mode
defaults to
NORMAL.

•
Do not rest your foot on the brake pedal
while driving.
• Avoid carrying unnecessary weight.
• Avoid adding particular accessories to
your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski
racks).
• Avoid driving with the wheels out of
alignment.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During this
time, your vehicle may exhibit some unusual
driving characteristics.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle. Note:
Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water, check
the depth. Never drive through water that is
higher than the bottom of the wheel hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that the
steering power assist works.
FLOOR MATS WARNING:
Use a floor mat designed
to fit the footwell of your vehicle that does
not obstruct the pedal area. Failure to
follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
Pedals that cannot move
freely can cause loss of vehicle control and
increase the risk of serious personal injury.
