Cross Traffic Alert System 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 could affect system
performance.
If the sensors are blocked, a message may
appear in the information display when you
shift into reverse (R). Cross Traffic Alert System Limitations
The system may not correctly operate when
any of the following occur:
•
The sensors are blocked.
• 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).

(12 km/h)
.
• You reverse out of an angled parking
space.
Cross Traffic Alert Behavior When
Trailer is Attached
Note: The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer. Cross traffic alert remains on when you
attach a trailer in vehicles that come with
blind spot information system with trailer tow
under the following conditions:
•
You connect a trailer.
• The trailer is a bike rack or cargo rack
with a maximum length of
3 ft (1 m).
• You set the trailer length to
3 ft (1 m) in
the information display.

Cross Traffic Alert Indicator
When the system 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 approaching vehicle is coming
from. Note:
If arrows do not display, a message
appears in the information display.
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:
In exceptional 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.

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.

2 If a message regarding a blocked sensor or
camera appears in the information display,
the radar signals or camera images have
become obstructed. If your vehicle has a
radar sensor, it is located behind a fascia
cover near the passenger side of the lower
grille. With an obstructed radar, the
Pre-Collision Assist system does not function
and cannot detect a vehicle ahead. With a
blocked sensor or camera, the Pre-Collision
Assist system may not function, or
performance may reduce. The following table
lists possible causes and actions for when
this message displays.
