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 - POLICE
RESPONDER
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 399).
The system is active at speeds above
3 mph (5 km/h)
. Note:
The pre-collision assist system
automatically disables when you select
four-wheel drive low, manually disable
AdvanceTrac ™, or select rock crawl mode.
Note: Brake support and automatic
emergency braking are active at speeds up
to
75 mph (120 km/h).
Pedestrian Detection Limitations
Pedestrian detection is active at speeds
up to
50 mph (80 km/h).
Pedestrian detection operates 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.
PRE-COLLISION ASSIST

WHAT IS TRAILER HITCHING
ASSISTANCE
Trailer hitching assistance helps the driver
align the vehicle hitch ball to a trailer
coupler.
HOW DOES TRAILER HITCHING
ASSISTANCE WORK
Trailer hitching assistance uses the
following to detect your trailer:
•
Rear view camera.
• Radar.
• Parking aid sensors.
• External rear lighting.
This feature also controls the following to
align the hitch ball with the trailer coupler:
• Steering.
• Shifting.

may result in a crash.
Note: Trailer hitching assistance only works
with conventional trailers, couplers and
hitch balls.
Note: The hitch ball must be properly
installed on the vehicle for the system to
function as intended. An improperly
installed hitch ball could result in damage
to your vehicle or trailer.
Note: Certain aftermarket modifications
such as oversized tires or lift kits could make
trailer hitching assistance fail or not work
as intended.
Note: Keep the sensors and camera free
from snow, ice and dirt.
Note: Clean the camera lens with a soft,
lint-free cloth and non-abrasive cleaner.
TRAILER HITCHING
ASSISTANCE LIMITATIONS
The system could not function or could
function with reduced performance during
the following:

WHAT IS TRAILER BACKUP
ASSISTANCE
Trailer backup assistance utilizes the
control knob on the instrument panel to
help you steer a trailer. Turn the control
knob in the direction you want the trailer
to go and the system steers the vehicle.
HOW DOES TRAILER BACKUP
ASSISTANCE WORK
Trailer backup assistance uses a sticker or
sensor attached to the trailer to detect the
trailer angle relative to the towing vehicle
and provides instructions, graphics and
camera views on the touchscreen.
TRAILER BACKUP
ASSISTANCE PRECAUTIONS
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. Always be aware of
your vehicle and trailer combination, and
the surrounding environment.
Note: The system does not detect or
prevent your vehicle or trailer from making
contact with obstacles in the surrounding
environment.
Note: The front end of your vehicle swings
out when changing the direction of the
trailer.
Note: In certain conditions, the trailer could
turn faster or the trailer angle could increase
more than anticipated. Always monitor the
clearance between the trailer and vehicle
and the surroundings.
SETTING UP THE TRAILER
BACKUP ASSISTANCE FOR A
CONVENTIONAL TRAILER
CONFIGURING THE TRAILER
You must configure a trailer in the system
to use trailer backup assistance. This is a
one-time setup process and the trailer
information is saved in the system for the
next time you use that trailer.
The system only works with conventional
trailers. It does not work with other types
including fifth-wheel and gooseneck. The
following illustration shows examples of
conventional trailers on the left-hand side.
