•
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 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
Alert
: When active, a flashing visual warning
appears and an audible warning tone
sounds.
298
Navigator (TB9) Canada/United States of America, enUSA, First-Printing Driving AidsE156130

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 system disables when you select
the Slow Climb or Deep Conditions drive
modes. 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.

TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum recommended
gross trailer weight exceeds the limit
of your vehicle and could result in
engine damage, transmission damage,
structural damage, loss of vehicle
control, vehicle rollover and personal
injury. WARNING:
Do not exceed the
GVWR or the GAWR specified on the
certification label.
Note: See
Recommended Towing
Weights (page 327).
Your vehicle may have electrical items,
such as fuses or relays, related to
towing.
See Fuses (page 360). Your vehicle's load capacity designation
is by weight, not by volume, so you
cannot necessarily use all available
space when loading a vehicle or trailer.
Towing a trailer places an extra load on
your vehicle's engine, transmission, axle,
brakes, tires and suspension. Inspect
these components periodically during,
and after, any towing operation.
Load Placement
To help minimize how trailer movement
affects your vehicle when driving:
•
Load the heaviest items closest to
the trailer floor.
• Load the heaviest items centered
between the left and right side trailer
tires. •
Load the heaviest items above the
trailer axles or just slightly forward
toward the trailer tongue. Do not
allow the final trailer tongue weight
to go above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the correct
rise or drop and load capacity. When
both the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly angled
down toward your vehicle, when
viewed from the side.
When driving with a trailer or payload, a
slight takeoff vibration or shudder may
be present due to the increased payload
weight. Additional information regarding
proper trailer loading and setting your
vehicle up for towing is located in
another chapter of this manual.
See
Load Limit (page 309).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.

TRAILER REVERSING AIDS (IF
EQUIPPED)
Pro Trailer Backup Assist™ WARNING:
Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the safe
operation of your vehicle. We recommend
against the use of any hand-held device
while driving and encourage the use of
voice-operated systems when possible.
Make sure you are aware of all applicable
local laws that may affect the use of
electronic devices while driving. WARNING:
This system is an extra
driving aid. It does not replace your
attention and judgment, or the need to
apply the brakes. This system does NOT
automatically brake your vehicle. If you fail
to press the brake pedal when necessary,
you may collide with another vehicle.
Note: The system is not a substitute for safe
driving practices.
Note: You must always be aware of the
vehicle and trailer combination and the
surrounding environment.
Note: The system does not detect or prevent
the vehicle or trailer from making contact
with obstacles in the surrounding
environment.
Note: Keep in mind that the front end of the
vehicle swings out when changing the
direction of the trailer. Note:
The system relies on user
measurements to determine sticker
placement and system limits. It is critical to
take the key measurements correctly.
Incorrect measurements can result in the
improper function of the system up to and
including contact between the vehicle and
trailer.
Note: The system limits vehicle speed when
backing up. The system is not a replacement
