2021 LINCOLN NAVIGATOR sensor

The radar sensor has a limited field of view.
It may not detect vehicles at all or detect a
vehicle later than expected in some
situations. The lead vehicle graphic does not
illuminate if the system does not detect a
vehicle in front of you. Detection issues can occur:
When driving on a different line
than the vehicle in front.
A
With vehicles that edge into your
lane. The system can only detect
these vehicles once they move
fully into your lane.
B
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. You should stay alert and take
action when necessary.
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.
Optimal performance may not occur if:

•
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.
Do not use the system in these conditions because it may not detect
any vehicles ahead.
Heavy rain or snow is interfering with the radar signals.

replace your attention and judgment. You
are still responsible to drive with due care
and attention. WARNING:
At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. Failure to take care may result in
the loss of control of your vehicle, serious
personal injury or death. WARNING:
The system may not
function if the sensor is blocked. WARNING: Take regular rest breaks
if you feel tired. Do not wait for the system
to warn you. WARNING:
Certain driving styles may
result in the system warning you even if
you are not feeling tired. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all limit
sensor performance. WARNING:
The system will not
operate if the sensor cannot track the road
lane markings. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. WARNING:
The system may not
correctly operate if your vehicle is fitted
with a suspension kit not approved by us.
Note: Keep the windshield free from
obstructions. For example, bird droppings,
insects and snow or ice.
Note: If the camera is blocked or if the
windshield is damaged, the system may not
function.
Note: If enabled in the menu, the system
activates at speeds above 40 mph (64 km/h). The system automatically monitors your
driving behavior using various inputs
including the front camera sensor.
If the system detects that your driving
alertness is reduced below a certain
threshold, the system will alert you using a
chime and a message in the information
display.

Using Driver Alert
Switching the system on and off
You may switch the system on or off through
the information display. See General
Information (page 134). When activated, the
system monitors your alertness level based
upon your driving behavior in relation to the
lane markings, and other factors.
System Warnings
Note: The system does not issue warnings
below approximately
40 mph (64 km/h).
The warning system is in two stages. At first
the system issues a temporary warning that
you need to take a rest. This message will
only appear for a short time. If the system
detects further reduction in driving alertness,
another warning may be issued which will
remain in the information display for a longer
time. Press OK on the steering wheel control
to clear the warning. When active the system
will run automatically in the background and
only issue a warning if required. Resetting the System

•
Switching the ignition off and on.
• Stopping your vehicle and then opening
and closing the driver’ s door.

System Lights and Messages
When the system detects a vehicle, an alert
indicator illuminates in the exterior mirror on
the side the approaching vehicle is coming
from. If you turn the direction indicator on for
that side of your vehicle, the alert indicator
flashes.
Note:
The system may not alert you if a
vehicle quickly passes through the detection
zone. Blocked Sensors
The sensors are behind the rear bumper on
both sides of your vehicle.
Note:
Keep the sensors free from snow, ice
and large accumulations of dirt.
Note: Do not cover the sensors with bumper
stickers, repair compound or other objects.
Note: Blocked sensors could affect system
performance.
If the sensors become blocked, a message
may appear in the information display. See
Information Messages (page 139). The alert
indicators remain illuminated but the system
does not alert you. Blind Spot Information System with
Trailer Tow
The system is designed to detect vehicles
that may have entered the blind spot zone
(A). The detection area is on both sides of
your vehicle and trailer, extending rearward
from the exterior mirrors to the end of your
trailer.
The system turns on when all of the following
occur:
•
You attach a trailer to your vehicle.
• You have set up the trailer to work with
the system through the information
display.

System Errors
If the system detects a fault, a warning lamp
illuminates and a message displays. See
Information Messages (page 139).
Switching the System On and Off
You can switch the system off using the
information display. See General Information
(page
134). When you switch the system off,
a warning lamp illuminates and a message
displays. When you switch the system on or
off, the alert indicators flash twice.
Note: The system remembers the last setting
when you start your vehicle.
Note: The system may not correctly operate
when towing a trailer. For vehicles with a
trailer tow module and tow bar approved by
us, the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer. To permanently switch the system off,
contact an authorized dealer.
CROSS TRAFFIC ALERT WARNING:
Do not use the cross
traffic alert system as a replacement for
using the interior and exterior mirrors or
looking over your shoulder before
reversing out of a parking space. The cross
traffic alert system is not a replacement for
careful driving. WARNING:
The system may not
operate properly during severe weather
conditions, for example snow, ice, heavy
rain and spray. Always drive with due care
and attention. Failure to take care may
result in a crash. The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
Using Cross Traffic Alert
The system detects vehicles that approach
at a speed between
4 mph (6 km/h) and
37 mph (60 km/h). Coverage decreases when
the sensors are partially, mostly or fully
obstructed. Slowly reversing helps increase
the coverage area and effectiveness.
The system turns on when you start the
engine and you shift into reverse (R). The
system turns off when you shift out of reverse
(R).

Zone coverage also decreases when parking
at narrow angles. The sensor on the left-hand
side is mostly obstructed and zone coverage
on that side is severely reduced.
