Zone coverage also decreases when
parking at narrow angles. The sensor on
the left-hand side is mostly obstructed and
zone coverage on that side is severely
reduced.
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).
• The vehicle speed is greater than 7 mph
(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.
See
Blind Spot Information System
(page 249).
Switching the System On and Off
To switch the system on or off, adjust the
setting. Depending on your vehicle options,
the setting could be in the following:
• Information display.
See General
Information (page 114).
• Touchscreen. See Settings (page 457).
Note: The system turns on every time you
switch the ignition on. To permanently
switch the system off, contact an authorized
dealer.
Cross Traffic Alert Indicator When the system detects an

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.

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 is designed to provide 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.
Brake Support
: The system is designed
to help reduce the impact speed by
preparing the brakes for rapid braking.
Brake support 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.
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
75 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: 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 leads to
fewer and later system warnings.
Note: The system disables when you select
4x4 low, sand mode, mud/ruts mode or
when you manually disable AdvanceTrac ™.
Distance Indication and Alert
(If
Equipped)
This 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.

Note:
If your vehicle has a radar sensor, we
recommend that you switch the system off
if you install a snowplow or similar object
in such a way that it could block the radar
sensor. Your vehicle remembers the selected
setting across key cycles.
Blocked Sensors If a message regarding a blocked sensor
or camera appears in the information
display, the radar signals or camera images
are obstructed. If your vehicle has a radar
sensor, it is located behind a fascia cover
near the driver 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.
Camera Troubleshooting Action
Cause
Clean the outside of the windshield in frontof the camera.
The windshield in front of the camera is
dirty or obstructed in some way.
Wait a short time. It may take several
minutes for the camera to detect that there is no obstruction.
The windshield in front of the camera is
clean but the message remains in the display screen.

minutes for the radar to detect that there is no obstruction.
The surface of the radar in the grille is clean
but the message remains in the display screen.
The pre-collision assist system is tempor-
arily disabled. Pre-collision assist automat- ically reactivates a short time after the weather conditions improve.
Heavy rain, spray, snow or fog is interfering
with the radar signals.
The pre-collision assist system is tempor-
arily disabled. Pre-collision assist automat- ically reactivates a short time after the weather conditions improve.
Swirling water or snow or ice on the surface
of the road may interfere with the radar signals.
Contact an authorized dealer to have theradar checked for proper coverage and operation.
Radar is out of alignment due to a front-
end impact.
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, the radar sensing
zone may change. This could cause missed
or false vehicle detections. Contact an
authorized dealer 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. This message
deactivates automatically when operational
conditions are correct. For example, when
the ambient temperature around the sensor
decreases or the sensor automatically
recalibrates successfully. DRIVE CONTROL
Selectable Drive Modes
The system delivers a driving experience
through a suite of sophisticated electronic
vehicle systems. These systems optimize
steering, handling and powertrain
response. This provides a single location
to control multiple systems performance
settings.
Changing the drive mode automatically
changes the functionality of the following
systems:
