light LINCOLN NAVIGATOR 2021 Repair Manual

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:

Active guidelines are only shown with fixed
guidelines. To use active guidelines, turn
the steering wheel to point the guidelines
toward an intended path. If you change the
steering wheel position while reversing, your
vehicle might deviate from the original
intended path.
The fixed and active guidelines fade in and
out depending on the steering wheel
position. The active guidelines do not
display when the steering wheel position is
straight.
Always use caution while reversing. Objects
in the red zone are closest to your vehicle
and objects in the green zone are farther
away. Objects are getting closer to your
vehicle as they move from the green zone
to the yellow or red zones. Use the side view
mirrors and rear view mirror to get better
coverage on both sides and rear of the
vehicle. Obstacle Distance Indicator (If Equipped)
The system will provide an image of your
vehicle and the sensor zones. The zones will
highlight green, yellow and red when the
parking aid sensors detect an object in the
coverage area.Manual Zoom WARNING:
When manual zoom is
on, the full area behind your vehicle may
not show. Be aware of your surroundings
when using the manual zoom feature.

WARNING: Adaptive cruise control
is not a crash warning or avoidance
system.
The system adjusts your vehicle speed to
maintain the set gap between you and the
vehicle in front of you in the same lane. You
can select four gap settings.
The system uses a radar sensor which
projects a beam directly in front of your
vehicle.
Note: It is your responsibility to stay alert,
drive safely and be in control of the vehicle
at all times. The cruise controls are on the steering
wheel. See Cruise Control (page 103).
Switching Adaptive Cruise Control On Press and release the button.
The indicator, current gap setting
and set speed appear in the
information display.
Setting the Adaptive Cruise Speed
Drive to your preferred speed.
Press and release the button.
Take your foot off the accelerator pedal. The indicator, current gap setting and set
speed appear in the information display.
Note:
When adaptive cruise control is active,
the speedometer may vary slightly from the
set speed displayed in the information
display.
Setting the Adaptive Cruise Speed
When Your Vehicle is Stationary
Follow a vehicle to a complete stop. Press while keeping the brake
pedal fully pressed.
The set speed adjusts to 20 mph (30 km/h).
The indicator, current gap setting and set

The camera is blocked.
• There is poor visibility or lighting
conditions.
• There are bad weather conditions.
System Not Available
Conditions that can cause the system to
deactivate or prevent the system from
activating when requested include:
• A blocked sensor.
• High brake temperature.
• A failure in the system or a related
system. Blocked Sensor A message displays if something obstructs
the radar signals from the sensor. The
sensor is in the lower grille. The system
cannot detect a vehicle ahead and does not
function when something blocks the sensor.
Note:
You cannot see the sensor. It is behind
a fascia panel.
Keep the front of your vehicle free of dirt,
metal badges or objects. Vehicle front
protectors and aftermarket lights may also
block the sensor.
Possible Causes and Actions for This Message Displaying: Action
Cause
Clean the grille surface in front of the radar or remove the object
causing the obstruction.
The surface of the radar is dirty or obstructed.
Wait a short time. It may take several minutes for the radar to detect
that it is free from obstruction.
The surface of the radar is clean but the message remains in the
display.

Action
Cause
Do not use the system in these conditions because it may not detect
any vehicles ahead.
Water, snow or ice on the surface of the road may interfere with the
radar signals.
Wait a short time or switch to normal cruise control.
You are in a desert or remote area with no other vehicles and no
roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no actual block. A false\
blocked condition either self
clears, or clears after you restart your vehicle.
Switching to Normal Cruise Control WARNING: Normal cruise control will
not brake when your vehicle is
approaching slower vehicles. Always be
aware of which mode you have selected
and apply the brakes when necessary. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you select
normal cruise control. The gap setting does
not display, and the system does not respond
to lead vehicles. Automatic braking remains
active to maintain set speed. You can change from adaptive cruise control
to normal cruise control through the
information display.
