steering LINCOLN NAUTILUS 2021 Service Manual

The brake indicator momentarily
illuminates when you switch the
ignition on to confirm the lamp is
functional. It may also illuminate when you
apply the parking brake and the ignition is
on. If it illuminates when your vehicle is
moving, make sure the parking brake is
disengaged. If the parking brake is
disengaged, this indicates low brake fluid
level or a brake system fault. See an
authorized dealer. Brakes – Information Messages The brake fluid level
is low and the brake
system should be
inspected immedi-
ately. See Checking the Brake Fluid (page 218).

Brakes – Frequently Asked Questions
Is brake dust on the wheels normal? Brake dust could 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 Wheels
(page 356). Will wet driving conditions effect my
braking abilities?
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.
Is brake noise considered normal? Occasional brake noise is normal. If a
metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out and an
authorized dealer should check them.
If the vehicle has continuous vibration
or shudder in the steering wheel while
braking, an authorized dealer should
check your vehicle.
When should you replace the brake fluid? Brake fluid absorbs water over time
which degrades the effectiveness of the
brake fluid. Change the brake fluid at
the specified intervals to prevent
degraded braking performance.

Normal Scheduled Maintenance (page
463

HOW DOES STABILITY CONTROL
WORK
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.
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.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control 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
Roll stability control 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.

ELECTRIC POWER STEERING
Electric Power Steering Precautions
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 vehicle off. After at least 10 seconds, switch
the vehicle 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. Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle manually
nor will it cause damage to the system.
Normal steering and driving allows the
system to cool down and steering assist
returns to normal.
Note:
There is no fluid reservoir to check or
fill.

Note:
If the detected object is 12 in (30 cm)
or less from your vehicle, visual indication
remains on.
SIDE PARKING AID
What is the Side Parking Aid
The front and rear outermost parking aid
sensors map objects that are near to the
sides of your vehicle.
Side Parking Aid Limitations
The sensor coverage is up to
24 in (60 cm)
from the sides of your vehicle.
The side parking aid may not function if:
• You switch your vehicle 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. •
Your vehicle is in park (P).
• The steering wheel angle information is
not available. You must drive at least
492 ft (150 m) above 19 mph (30 km/h) to
reset the steering wheel angle
information.
Note: If you switch traction control off, the
side sensing system also turns off.
To reinitialize the system, drive the length of
your vehicle.
The side parking aid does not detect an
object that is moving toward the side of your
vehicle, for example another vehicle moving
at a low speed, if it does not pass a front or
rear parking aid sensor.
If the transmission is in reverse (R), the side
sensing system provides audible warnings.
When your vehicle is moving slowly,
obstacles are detected within
24 in (60 cm)
and are inside the driving path of your
vehicle. Once your vehicle reaches a
standstill condition, the audible warning
stops after a few seconds. Visual indication
is always present in reverse (R). If your vehicle is in neutral (N), the side
sensing system provides visual indication
only when your vehicle is moving slowly and
there is a front or rear park aid obstacle
detected, and the side obstacle is within
24 in (60 cm)
from the side of your vehicle.
Once your vehicle reaches a stop, the visual
indication stops after a few seconds.
If the transmission is in drive (D) or any other
forward gear, the side sensing system
provides audible and visual warnings. When
your vehicle is moving slowly, obstacles are
detected within
24 in (60 cm) and are inside
the driving path of your vehicle. Once your
vehicle reaches a standstill condition, the
audible warning and visual indication stops
after a few seconds.
