Following a Vehicle
WARNING: When following a vehicle,
your vehicle does not always decelerate
quickly enough to avoid a crash without
driver intervention. Always apply the
brakes when necessary. Failing to do so
may result in a crash, serious injury or
death. WARNING: Adaptive cruise control
only warns of vehicles detected by the
radar sensor. In some cases there may be
no warning or a delayed warning. You
should always apply the brakes when
necessary. Failure to do so may result in a
crash, serious injury or death.
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 a preset gap distance. A vehicle
graphic illuminates in the instrument cluster.
Note: The brakes may emit noise when
applied by the system. Note:
When you are following a vehicle and
you switch on a direction indicator, 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 your
vehicle to maintain a safe gap distance from
the vehicle in front. The system only applies
limited braking. You can override the system
by applying the brakes.
If the system determines that its maximum
braking level is not sufficient, an audible
warning sounds, a message appears in the
information display and an indicator flashes
when the system continues to brake. Take
immediate action. Following a Vehicle to 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 to follow the vehicle ahead.
Or press the accelerator pedal.
Setting the Gap Distance
You can decrease or increase the distance
between your vehicle and the vehicle in front
by pressing the gap control. Press and release to decrease the
gap distance.
Press and release to increase the
gap distance.

The selected gap appears in the information
display as shown by the bars in the image.
Note:
The gap setting is time dependent and
therefore the distance adjusts with your
vehicle speed.
Note: It is your responsibility to select a gap
appropriate to the driving conditions. Adaptive Cruise Control Gap Settings Dynamic

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 normally
to intentionally exceed the set
speed limit.
When you override the system, the green
indicator light illuminates and the vehicle
image does not appear in the information
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.
Changing the Set Speed Press and release to increase the
set speed in small increments.
Press and release to decrease the
set speed in small increments.
Press and hold either button to change the
set speed in large increments. Release the
button when you reach your preferred speed.

The system may apply the brakes to slow
the vehicle to the new set speed. The set
speed displays continuously in the
information display when the system is
active.
Canceling the Set Speed
Press and release the button or tap
the brake pedal.
The set speed does not erase.
Resuming the Set Speed Press and release 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.
Automatic Cancellation
Automatic cancellation can also occur when: •
The tires lose traction.
• You apply the parking brake.
Park Brake Application
Automatic parking brake application and
cancellation occurs if:
• You unbuckle the seatbelt and open the
door after you stop the vehicle.
• You hold the vehicle at a stop
continuously for more than three minutes.
Hilly Condition Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep grades,
for example in mountainous areas. The
system needs additional engine braking in
these situations to reduce the load on the
vehicle ’s regular brake system to prevent it
from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for an
extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool. Switching Adaptive Cruise Control Off Press and release the button when
the system is in standby mode, or
switch the ignition off.
Note: You erase the set speed and gap
setting when you switch the system off.
Detection Issues WARNING: On rare occasions,
detection issues can occur due to the road
infrastructures, for example bridges,
tunnels and safety barriers. In these cases,
the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening, if
required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.
273
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Cruise Control E265299 E265297

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.

Action
Cause
Do not use the system in these conditions because it may not detect
any vehicles ahead.
Water, snow or ice on the surface of the road may interfere with the
radar signals.
Wait a short time or switch to normal cruise control.
You are in a desert or remote area with no other vehicles and no
roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no actual block. A false\
blocked condition either self
clears, or clears after you restart your vehicle.
Switching to Normal Cruise Control 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. 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. You can change from adaptive cruise control
to normal cruise control through the
information display.

STEERING
Electric Power Steering
WARNING: The electric power
steering system has diagnostic checks that
continuously monitor the system. If a fault
is detected, a message displays in the
information display. Stop your vehicle as
soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked as soon as possible. WARNING:
If the system detects an
error, you may not feel a difference in the
steering, however a serious condition may
exist. Have your vehicle checked as soon
as possible. Failure to do so may result in
loss of steering control.
Your vehicle has an electric power steering
system, there is no fluid reservoir, no
maintenance is required. If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle, this increased effort prevents
overheating and permanent damage to the
steering system. You do not lose the ability
to steer your vehicle manually. Typical
steering and driving maneuvers allow the
system to cool and return to normal
operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• Uneven tire wear.
• Loose or worn suspension components.
• Loose or worn steering components.
• Improper vehicle alignment. Note:
A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
(If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with the
brake system to help operate advanced
stability control and accident avoidance
systems. Additionally, whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short distance
before the system relearns the strategy and
reactivates all systems.

PRE-COLLISION ASSIST
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:
The system does not
detect vehicles moving in a different
direction 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
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:
Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types, and
pedestrians. 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 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.
Using the Pre-Collision Assist System
The Pre-Collision Assist system is active at
speeds above approximately 3 mph (5 km/h)
and pedestrian detection is active at speeds
up to
50 mph (80 km/h). 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
three levels of functionality:
1. Alert
2. Brake Support
3. Active Braking
294
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Driving AidsE156130

Alert: When active, a flashing visual warning
appears and an audible warning tone
sounds.
Brake Support
: The system helps reduce
the impact speed by preparing the brakes
for rapid braking. Brake support does not
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.
Active Braking
: Active braking may activate
if the system determines that a collision is
imminent. The system may help the driver
reduce impact damage or avoid the crash
completely.
Note: Brake Support and Active Braking are
active at speeds up to 74.6 mph (120 km/h).
If the vehicle has a radar sensor or Adaptive
Cruise Control, then Brake Support and
Active Braking are active up to the maximum
speed of the vehicle.
Note: The Active Braking capability of the
system disables when you select the SLOW
CLIMB
drive mode. Note:
If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends using
the highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings.
Distance Indication and Alert
(If Equipped)
Distance Indication and Alert is a function
that provides you with a graphical indication
of the time gap to other preceding vehicles
traveling in the same direction. The Distance
Indication and Alert screen in the information
display shows one of the following graphics. If the time gap to a preceding vehicle is
small, a red visual indication appears.
Note:
Distance Indication and Alert
deactivates, and the graphics do not display
when adaptive cruise control is active.

operation at Gross Vehicle Weight
Rating, not at Gross Combined Weight
Rating.) Separate functional brakes
should be used for safe control of towed
vehicles and for trailers where the Gross
Combined Weight of the towing vehicle
plus the trailer exceed the Gross Vehicle
Weight Rating of the towing vehicle.
The gross combined weight must never
exceed the Gross Combined Weight
Rating.
Note:
For trailer towing information
refer to the RV and Trailer Towing Guide
available at an authorized dealer. WARNING: Do not exceed the
GVWR or the GAWR specified on the
certification label. WARNING:
Do not use
replacement tires with lower load
carrying capacities than the original
tires because they may lower your
vehicle's GVWR and GAWR limitations.
Replacement tires with a higher limit
than the original tires do not increase
the GVWR and GAWR limitations. WARNING:
Exceeding any
vehicle weight rating can adversely
affect the performance and handling
of your vehicle, cause vehicle damage
and can result in the loss of control of
your vehicle, serious personal injury
or death.
Steps for determining the correct load
limit:
1. Locate the statement "The combined
weight of occupants and cargo
should never exceed XXX kg or XXX
lb." on your vehicle ’s placard. 2.
Determine the combined weight of
the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the
driver and passengers from XXX kg
or XXX lb.
4. The resulting figure equals the available amount of cargo and
luggage load capacity. For example,
if the “XXX” amount equals 1,400 lb.
and there will be five 150 lb.
passengers in your vehicle, the
amount of available cargo and
luggage load capacity is 650 lb.
(1400-750 (5 x 150) = 650 lb.)
5. Determine the combined weight of
luggage and cargo being loaded on
the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calculated
in Step 4.
