Each time you switch the system on, it
selects the last chosen gap setting. Following a Vehicle
When a vehicle ahead of you enters the
same lane or a slower vehicle is ahead in the
same lane, the vehicle speed adjusts to
maintain the gap setting.
Note:
When you are following a vehicle and
you switch on a turn signal lamp, adaptive
cruise control may provide a small,
temporary acceleration to help you pass.
Your vehicle maintains a consistent gap from
the vehicle ahead until:
• The vehicle in front of you accelerates to
a speed above the set speed.
• The vehicle in front of you moves out of
the lane you are in.
• You set a new gap distance.
The system applies the brakes to slow down
your vehicle to maintain a safe gap distance
from the vehicle in front of you. The system
only applies limited braking. You can
override the system by applying the brakes.
Note: The brakes may emit noise when
applied by the system.

If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds, a message appears in the
instrument cluster display and an indicator
flashes when the system continues to brake.
Take immediate action.
CANCELING THE SET SPEED
Press the button or tap the brake
pedal.
The set speed does not erase.
RESUMING THE SET SPEED Press the button.
Your vehicle speed returns to the previously
set speed and gap setting. The set speed
displays continuously in the information
display when the system is active.
Note: Only use resume if you are aware of
the set speed and intend to return to it. Resuming the Set Speed from a
Complete Stop
If your vehicle follows a vehicle to a complete
stop and remains stationary for less than
three seconds, your vehicle accelerates from
a stationary position to follow the vehicle
ahead.
If your vehicle follows a vehicle to
a complete stop and remains
stationary for more than three
seconds, press and release the button or
press the accelerator pedal to follow the
vehicle ahead.
OVERRIDING THE SET SPEED WARNING: If you override the system
by pressing the accelerator pedal, it does
not automatically apply the brakes to
maintain a gap from any vehicle ahead.
When you press the accelerator pedal, you
override the set speed and gap distance. Use the accelerator pedal to intentionally
exceed the set speed limit.
When you override the system, the green
indicator illuminates and the vehicle icon
does not appear in the instrument cluster
display.
The system resumes operation when you
release the accelerator pedal. The vehicle
speed decreases to the set speed, or a lower
speed if following a slower vehicle.

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.
You can change from adaptive cruise control
to normal cruise control through the
information display. 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. LANE CENTERING
How Does Lane Centering Work
Adaptive cruise control with lane centering
uses radar and camera sensors to help keep
your vehicle in the lane by applying
continuous assistance steering torque input
toward the lane center on highways.
Note:
The adaptive cruise control gap setting
operates normally.
Lane Centering Precautions WARNING:
Do not use the system
when towing a trailer. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING: Do not use the system if
any changes or modifications to the

WHAT IS PRE-COLLISION ASSIST
Pre-collision assist detects and warns of
approaching hazards in the roadway. If your
vehicle is rapidly approaching another
stationary vehicle, a vehicle traveling in the
same direction as yours, or a pedestrian
within your driving path, the system provides
multiple levels of assistance to help avoid a
collision.
HOW DOES PRE-COLLISION
ASSIST WORK
Pre-Collision Assist with Automatic
Emergency Braking
The system warns the driver of potential
hazards by providing three levels of
assistance.
If your vehicle is rapidly approaching
potential hazards, the system provides the
following levels of functionality:
1. Alert.
2. Brake Support.
3. Automatic Emergency Braking. Alert: When active, a flashing visual warning
appears and an audible warning tone
sounds.
Brake Support
: The system is designed to
help reduce the impact speed by preparing
the brakes for rapid braking. The system
does not automatically apply the brakes. If
you press the brake pedal, the system could
apply additional braking up to maximum
braking force, even if you lightly press the
brake pedal.
Automatic Emergency Braking
: Automatic
emergency braking could activate if the
system determines that a collision is
imminent. Note:
If you perceive pre-collision assist
alerts as being too frequent or disturbing,
then you could reduce the alert sensitivity.
The manufacturer recommends using the
highest sensitivity setting where possible.
Setting a lower sensitivity would lead to
fewer and later system warnings.
Each system has various levels of detection
capabilities.
See Pre-Collision Assist
Limitations (page 280).
PRE-COLLISION ASSIST
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.

2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing Pre-Collision AssistE255268

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.

AUTOMATIC EMERGENCY BRAKING
What Is Automatic Emergency Braking
Automatic emergency braking may activate
if the system determines that a collision is
imminent. The system may help reduce
impact damage to avoid the crash
completely.
Automatic emergency braking is only
available up to certain speeds. See
Pre-Collision Assist Limitations (page 280).
Switching Automatic Emergency
Braking On and Off
To switch the system on or off, use the
instrument cluster display:
1. Using the instrument cluster display controls on the steering wheel, select
SETTINGS
.
2. Select

EVASIVE STEERING ASSIST (If
Equipped)
What Is Evasive Steering Assist
If your vehicle is rapidly approaching a road
user, evasive steering assist helps you steer
around the road user.
After you turn the steering wheel in an
attempt to avoid a crash with the road user,
the system applies additional steering torque
to help you steer around the road user. After
you pass the road user, the system applies
steering torque when you turn the steering
wheel to steer back into the lane. The system
deactivates after you fully pass the road user.
Note: Road users are defined as obstacles
encountered on the road that the system is
able to detect.
See Pre-Collision Assist
Precautions (page 279). Evasive Steering Assist Limitations
Evasive steering assist only activates when
all the following occur:
•
Automatic emergency braking and
evasive steering assist are on.
• The system detects a road user ahead
and starts to apply the brakes.
• You significantly turn the steering wheel
to steer around a road user.
Note: The system does not automatically
steer around a road user. If you do not turn
the steering wheel, the system does not
activate.
Note: The system does not activate if the
distance to the road user ahead is too small
and the system cannot avoid a crash.
Switching Evasive Steering Assist On
and Off
To switch the system on or off, use the
