BLIND SPOT INFORMATION
SYSTEM INDICATORS When blind spot information
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 turn signal on
for that side of your vehicle, the alert
indicator flashes.

WHAT IS CROSS TRAFFIC ALERT
The system alerts you of vehicles
approaching from the sides behind your
vehicle when you shift into reverse (R).
HOW DOES CROSS TRAFFIC
ALERT WORK
Cross Traffic Alert detects vehicles that
approach at a speed between 4–37 mph
(6–60 km/h). Coverage decreases when the
sensors are partially, mostly or fully
obstructed. The sensor on the left-hand side is only
partially obstructed and zone coverage on
the right-hand side is maximized. 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.
Note:
Slowly reversing helps increase the
coverage area and effectiveness. CROSS TRAFFIC ALERT
PRECAUTIONS 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.

CROSS TRAFFIC ALERT
LIMITATIONS
Cross Traffic Alert may not correctly operate
when any of the following occur:
•
Something is blocking the sensors.
• Adjacently parked vehicles or objects are
obstructing the sensors.
• Vehicles approach at speeds less than
4 mph (6 km/h) or greater than 37 mph
(60 km/h).
• Your vehicle speed is greater than 7 mph
(12 km/h)
.
• You reverse out of an angled parking
space.
SWITCHING CROSS TRAFFIC
ALERT ON AND OFF
To switch cross traffic alert on or off use the
instrument cluster display:
1. Using the instrument cluster display controls on the steering wheel, select
SETTINGS
. 2. Select
Driver assistance.
3. Switch
Cross traffic alert on or off.
LOCATING THE CROSS TRAFFIC
ALERT 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 may affect system
accuracy. If something is blocking the sensors, a
message may appear in the information
display when you shift into reverse (R).
CROSS TRAFFIC ALERT
INDICATORS
When the cross traffic alert detects
an approaching vehicle, a tone
sounds, a warning lamp illuminates
in the relevant exterior mirror and arrows
appear in the information display to show
which side the vehicle is approaching from.
If the system malfunctions, a warning lamp
illuminates in the instrument cluster and a
message appears in the information display.
Have your vehicle checked as soon as
possible.
Note: If arrows do not display, a message
appears in the information display.
Note: In some conditions, the system could
alert you, even when there is nothing in the
detection zone, for example a vehicle
passing further away from your vehicle.

WARNING: The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury. WARNING:
The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
Take additional care if
your vehicle is heavily loaded or you are
towing a trailer. These conditions could
result in reduced performance of this
system. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
The system cannot help
prevent all crashes. Do not rely on this
system to replace driver judgment and the
need to maintain a safe distance and
speed. WARNING:
In situations where the
vehicle camera has limited detection
capability, this may reduce system
performance. These situations include but
are not limited to direct or low sunlight,
vehicles at night without tail lights,
unconventional vehicle types, pedestrians
with complex backgrounds, running pedestrians, partly obscured pedestrians,
or pedestrians that the system cannot
distinguish from a group. Failure to take
care may result in the loss of control of
your vehicle, serious personal injury or
death.
PRE-COLLISION ASSIST
LIMITATIONS
Pre-collision assist depends on the detection
ability of its camera and sensors. Any
obstructions or damage to these areas can
limit detection or prevent the system from
functioning. See Locating the Pre-Collision
Assist Sensors (page 281).
The system is active at speeds above 3 mph
(5 km/h)
Note: The pre-collision assist system
disables when you select four-wheel drive
low or manually disable AdvanceTrac ™.

2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing Pre-Collision Assist

Note:
Brake support and automatic
emergency braking are active at speeds up
to 75 mph (120 km/h). If the vehicle has a
radar sensor included with adaptive cruise
control, then brake support and automatic
emergency braking are active up to the
maximum speed of the vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speeds up
to
50 mph (80 km/h).
Pedestrian detection functions optimally
when detected hazards are clearly
identifiable. System performance may reduce
in situations where pedestrians are running,
partly obscured, have a complex
background, or cannot be distinguished from
a group. LOCATING THE PRE-COLLISION
ASSIST SENSORS
Camera.
1
Radar sensor (if equipped).
2
If a message regarding a blocked sensor or
camera appears in the information display,
something is obstructing the radar signals or
camera images. The radar sensor is behind
the fascia cover in the center of the lower
grille. With a blocked sensor or camera, the
system may not function, or performance
may reduce.
See Pre-Collision Assist –
Information Messages (page 285). Note:
Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note: If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
could change. This could cause missed or
false vehicle detections. Have your vehicle
serviced to have the radar checked for
proper coverage and operation.
Note: If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message could 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 recalibrates successfully.

WHAT IS DRIVER ALERT
Driver alert alerts you if it determines that
you are becoming drowsy or if your driving
deteriorates.
HOW DOES DRIVER ALERT WORK
Driver Alert calculates your alertness level
based on your driving behavior in relation to
the lane markings and other factors through
use of the front camera sensor behind the
interior mirror. DRIVER ALERT PRECAUTIONS
WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. 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. WARNING:
The system may not
operate properly if the sensor is blocked.
Keep the windshield free from obstruction.
Note: If something is blocking the camera
or damaged the windshield, Driver Alert may
not function.
