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.
279
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 ™.
280
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.

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.
