2017 LINCOLN NAVIGATOR sensor

PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, please
read and understand the limitations of
the system as contained in this section.
Sensing is only an aid for some (generally
large and fixed) objects when moving on a
flat surface at parking speeds. Certain
objects with surfaces that absorb ultrasonic
waves, surrounding vehicle's parking aid
systems, traffic control systems, fluorescent
lamps, inclement weather, air brakes, and
external motors and fans may also affect the
function of the sensing system; this may
include reduced performance or a false
activation. To help avoid personal injury, always
use caution when in reverse (R) and
when using the sensing system. WARNINGS
This system is not designed to prevent
contact with small or moving objects.
The system is designed to provide a warning
to assist the driver in detecting large
stationary objects to avoid damaging your
vehicle. The system may not detect smaller
objects, particularly those close to the
ground. Certain add-on devices such as large
trailer hitches, bike or surfboard racks
and any device that may block the normal
detection zone of the system, may create
false beeps. Note:
Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system’ s accuracy can be
affected. Do not clean the sensors with sharp
objects.
Note: If your vehicle sustains damage to the
bumper or fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. Note:
The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation (page 54).
Note: If you attach certain add-on devices
such as a trailer or bike rack, the rear
sensing system may detect that add-on
device and therefore provide warnings. It is
suggested that you disable the rear sensing
system when you attach an add-on device
to your vehicle to prevent these warnings.
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on. You can turn the system on or off
by pressing the parking aid button.
If your vehicle does not have a
parking aid button, the system can be
switched off through the information display
menu or from the pop-up message that
appears once you shift the transmission into
reverse (R).
See General Information (page
102).
If a fault is present in the system, a warning
message appears in the information display.
See
Information Messages (page 108).

REAR PARKING AID
The rear sensors are only active when the
transmission is in reverse (R). As your vehicle
moves closer to the obstacle, the rate of the
audible warning increases. When the
obstacle is less than 12 in (30 cm) away, the
warning sounds continuously. If the system
detects a stationary or receding object
farther than
12 in (30 cm) from the corners of
the bumper, the tone sounds for only three
seconds. Once the system detects an object
approaching, the warning sounds again. Coverage area of up to
6 ft (1.8 m) from the
rear bumper. There may be decreased
coverage area at the outer corners of the
bumper.
The system detects certain objects while the
transmission is in reverse (R) :
• Your vehicle is moving toward a
stationary object at a speed of
3 mph
(5 km/h) or less.
• Your vehicle is not moving, but a moving
object is approaching the rear of your
vehicle at a speed of
3 mph (5 km/h) or
less.
• Your vehicle is moving at a speed of less
than 3 mph (5 km/h) and a moving object
is approaching the rear of your vehicle
at a speed of less than
3 mph (5 km/h).
The system provides audio warnings only
when your vehicle is moving or when your
vehicle is stationary and the detected
obstacle is less than 12 in (30 cm) away from
the bumper. Obstacle Distance Indicator
(If Equipped)
The system provides obstacle distance
indication through the information display.
The distance indicator displays when the
transmission is in reverse (R).
The indicator displays:
• As the distance to the obstacle
decreases the indicator blocks illuminate
and move towards the vehicle icon.
• If there is no obstacle detected, the
distance indicator blocks are grayed out.
FRONT PARKING AID
The front parking aid sensors automatically
turn on when you shift into reverse (R) or a
forward gear.
The front sensors are active when the
transmission is in any position other than
park (P) and the vehicle speed is below
7 mph (12 km/h)
.

Navigator (TB5) Canada/United States of America, enUSA, First Printing Parking AidsE130178

Coverage area of up to 28 in (70 cm) from
the front bumper. There is decreased
coverage area at the outer corners.
The system sounds an audible warning when
obstacles are near either bumper in the
following manner:
• Objects detected by the front sensors
are indicated by a high-pitched tone from
the front of the vehicle.
• Objects detected by the rear sensors are
indicated by a lower pitched tone from
the rear of the vehicle. •
The sensing system reports the obstacle
which is closest to the front or rear of the
vehicle. For example, if an obstacle is
12 in (30 cm) from the front of the vehicle
and, at the same time, an obstacle is only
6 in (15 cm)
from the rear of the vehicle,
the lower pitched tone sounds.
• An alternating warning sounds from the
front and rear if there are objects at both
bumpers that are closer than
12 in
(30 cm).
The system provides warnings when your
vehicle is moving or when your vehicle is
stationary and the detected obstacle is less
than
12 in (30 cm) away from the bumper.
REAR VIEW CAMERA WARNINGS
The rear view camera system is a
reverse aid supplement device that still
requires the driver to use it in conjunction
with the interior and exterior mirrors for
maximum coverage. WARNINGS
Objects that are close to either corner
of the bumper or under the bumper,
might not be seen on the screen due to the
limited coverage of the camera system. Back up as slow as possible since
higher speeds might limit your reaction
time to stop your vehicle. Use caution when using the rear video
camera and the luggage compartment
door is ajar. If the luggage compartment door
is ajar, the camera will be out of position and
the video image may be incorrect. All
guidelines disappear when the luggage
compartment door is ajar. Use caution when turning camera
features on or off. Make sure your
vehicle is not moving. The rear view camera system provides a
video image of the area behind your vehicle.
During operation, lines appear in the display
which represent your vehicle
’s path and
proximity to objects behind your vehicle.

BLIND SPOT INFORMATION
SYSTEM
WARNING
Never use the Blind Spot Information
System as a replacement for using the
interior and exterior mirrors or looking over
your shoulder before changing lanes. The
Blind Spot Information System is not a
replacement for careful driving. The Blind Spot Information System is
designed to aid you in detecting vehicles
that may have entered the blind spot zone
(A). The detection area is on both sides of
your vehicle, extending rearward from the
exterior mirrors to approximately 10 ft (3 m)
beyond the bumper. The system is designed
to alert you if certain vehicles enter the blind
spot zone while driving.
Cross Traffic Alert warns the driver of
vehicles approaching from the sides when
the transmission is in reverse (R).
Note: The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor detect parked vehicles,
people, animals or infrastructure (fences,
guardrails, trees). It’ s only designed to alert
you to vehicles in the blind spot zones.
Note: When a vehicle passes quickly through
the blind spot zone, typically fewer than two
seconds, the system does not trigger. Using the System
The Blind Spot Information System turns on
when you start the engine and you drive your
vehicle forward above
3 mph (5 km/h). It
remains on while the transmission is in drive
(D) or neutral (N). If shifted out of drive (D) or
neutral (N), the system enters Cross Traffic
Alert mode. Once shifted back into drive (D),
the Blind Spot Information System turns back
on when the vehicle is driven above
3 mph
(5 km/h).
Note: The Blind Spot Information System
does not function in reverse (R) or park (P)
or provide any additional warning when a
turn signal is on.
Cross Traffic Alert detects approaching
vehicles from up to 46 ft (14 m) away though
coverage decreases when the sensors are
blocked. Reversing slowly helps increase the
coverage area and effectiveness.

WARNING
Never use the Cross Traffic Alert
system as a replacement for using the
interior and exterior mirrors and looking over
your shoulder before backing out of a
parking space. Cross Traffic Alert is not a
replacement for careful driving. In this first example, the left sensor is only
partially obstructed; zone coverage to the
right is nearly maximized.
202
Navigator (TB5) Canada/United States of America, enUSA, First Printing Driving AidsE142440

Zone coverage also decreases when parking
at shallow angles. Here, the left sensor is
mostly obstructed; zone coverage on that
side is severely limited. 203
Navigator (TB5) Canada/United States of America, enUSA, First Printing Driving AidsE142441

System Lights and Messages
The Blind Spot Information and Cross Traffic
Alert systems illuminate an amber alert
indicator in the outside mirror on the side of
your vehicle the approaching vehicle is
coming from.
The alert indicator dims when the system
detects nighttime darkness. Cross Traffic Alert sounds also sounds an
audible alarm and a message appears in the
information display indicating a vehicle is
coming from the right or left. Cross Traffic
Alert works with the reverse sensing system
which sounds its own audible alarm. See
Rear Parking Aid (page 194).
System Sensor Blockage WARNING
Never
use the Blind Spot Information
System as a replacement for using the
interior and exterior mirrors or looking over
your shoulder before changing lanes. The
Blind Spot Information System is not a
replacement for careful driving. Note:
It is possible to get a blockage warning
with no blockage present; this is rare and
known as a false blockage warning. A false
blocked condition either self-corrects or
clears after a key cycle. 204
Navigator (TB5) Canada/United States of America, enUSA, First Printing Driving AidsE142442 E205199

The system uses radar sensors which are
located behind the bumper fascia on each
side of your vehicle. Do not allow these areas
to become obstructed by mud, snow or
bumper stickers, as this can cause degraded
system performance.
If the system detects a degraded
performance condition, a blocked sensor
warning or low visibility warning will appear
in the information display and the alert
indicator illuminates in the appropriate
mirror(s). The information display warning
can be cleared but the alert indicator remains
illuminated.When the blockage is removed, the system
can be reset in two ways: 1) when at least
two objects are detected while driving, or 2)
turn the ignition key from on to off, then back
on. If the blockage is still present after the
key cycle, the system senses again that it is
blocked after driving in traffic. Reasons for messages being displayed
Clean the fascia area in front of the radar or remove the obstruction.
The radar surface is dirty or obstructed
Drive normally in traffic for a few minutes to allow the radar to detect\
passing vehicles so it can clear the blocked state.
The radar surface is not dirty or obstructed
No action required. The system automatically resets to an unblockedstate once the rainfall/snowfall rate decreases or stops. Do not use the Blind Spot Information System or Cross Traffic Alert in these conditions.
Heavy rainfall/snowfall interferes with the radar signals
System Limitations
The Blind Spot Information and Cross Traffic
Alert systems do have their limitations;
situations such as severe weather conditions
or debris build-up on the sensor area may
limit vehicle detection. 205
