While audible signals are emitted, the audio system is
muted.
The audible signal is turned off immediately if the distance
increases. The tone cycle remains constant if the distance
measured by the inner sensors is constant. If this condition occurs
for the external sensors, the signal is turned off after three seconds
(stopping warnings during maneuvers parallel to walls).

ParkSense Rear Park Assist Failure Indications
A malfunction of the ParkSense sensors or system is indi
-
cated, during REVERSE gear engagement, by the instrument
panel warning icon.
The warning icon is illuminated and a message is
displayed on the instrument cluster display (if
equipped). Refer to “Warning Lights And
Messages” in “Getting To Know Your Instrument Panel” for
further information.

The sensors and wiring are tested continuously when the
ignition is in the MAR (ACC/ON/RUN) position. Failures are
indicated immediately if they occur when the system is on.

Even if the system is able to identify that a specific sensor is
in failure condition, the instrument cluster display shall
indicate that the ParkSense system is unavailable, without
reference to the sensor in failure condition. If even a single
sensor fails, the entire system must be disabled. The system
is turned off automatically.

STARTING AND OPERATING 179
If it’s necessary to keep the ball mount and hitch ball
assembly mounted for a long period, it is possible to filter out
the ball mount and hitch ball assembly presence in sensor
field of view. The filtering operation must be performed only
by an authorized dealer.
PARKVIEW REAR BACK UP CAMERA
Your vehicle is equipped with the ParkView Rear Back Up
Camera that allows you to see an on-screen image of the rear
surroundings of your vehicle whenever the gear selector is
put into REVERSE. The image will be displayed on the
touchscreen display along with a caution note to “check
entire surroundings” across the top of the screen. After five
seconds this note will disappear. The ParkView camera is
located on the rear of the vehicle above the rear license plate.

The Rear Back Up Camera can also be activated when the
vehicle is not in REVERSE through the Uconnect System. Refer
to “Uconnect Settings” in “Multimedia” for further information.

NOTE:
If one of the rear cargo doors is not completely closed, the
Back Up Camera cannot provide an accurate image of the
area behind the vehicle. A dedicated message will appear on
the Uconnect display indicating the camera is not in the
correct position.
• Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly is discon -
nected from the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury or damage
to vehicles or obstacles because the hitch ball will be
much closer to the obstacle than the rear fascia when
the loudspeaker sounds the continuous tone. Also, the
sensors could detect the ball mount and hitch ball
assembly, depending on its size and shape, giving a
false indication that an obstacle is behind the vehicle.
CAUTION!
• ParkSense is only a parking aid and it is unable to recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
• The vehicle must be driven slowly when using Park -
Sense in order to be able to stop in time when an
obstacle is detected. It is recommended that the driver
looks over his/her shoulder when using ParkSense.

180 STARTING AND OPERATING
The Camera Delay setting can be set to on/off in the rear
camera settings menu. When the vehicle is shifted out of
REVERSE and the Camera Delay is turned off, the rear
camera mode is exited and the navigation or audio screen
appears on display again.
When the transmission is shifted out of REVERSE, and
Camera Delay is activated in the menu screen, the camera
image will continue to be displayed for up to 10 seconds,
unless the speed of the vehicle is greater than 8 mph (13 km/h), the transmission is in PARK, or the ignition is placed in
the OFF position.
When displayed, static grid lines will illustrate the width of
the vehicle and will show separate zones that will help
indicate the distance to the rear of the vehicle. The following
table shows the approximate distances for each zone:
NOTE:
If snow, ice, mud, or any foreign substance builds up on the
camera lens, clean the lens, rinse with water, and dry with a
soft cloth. Do not cover the lens.
Zone
Distance To The Rear Of The
Vehicle
Red 0 - 1 ft (0 - 30 cm)
Yellow 1 ft - 3 ft (30 cm - 1 m)
Green 3 ft or greater (1 m or greater)WARNING!
Drivers must be careful when backing up even when
using the ParkView Rear Back Up Camera. Always check
carefully behind your vehicle, and be sure to check for
pedestrians, animals, other vehicles, obstructions, or
blind spots before backing up. You are responsible for
the safety of your surroundings and must continue to
pay attention while backing up. Failure to do so can
result in serious injury or death.
CAUTION!
• To avoid vehicle damage, ParkView should only be used as a parking aid. The ParkView camera is unable
to view every obstacle or object in your drive path.
• To avoid vehicle damage, the vehicle must be driven slowly when using ParkView to be able to stop in time
when an obstacle is seen. It is recommended that the
driver look frequently over his/her shoulder when
using ParkView.

Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact sparetire.
• Do not drive more than 50 mph (80 km/h) when towing while using a full size spare tire.
• Proper tire inflation pressures are essential to the safe and satisfactory operation of your vehicle. Refer to “Tires” in
“Servicing And Maintenance” for proper tire inflation
procedures.
• Check the trailer tires for proper tire inflation pressures before trailer usage.
• Check for signs of tire wear or visible tire damage before towing a trailer. Refer to “Tires” in “Servicing And Main -
tenance” for the proper inspection procedure.
• When replacing tires, refer to “Tires” in “Servicing And Maintenance” for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits. Towing Requirements — Trailer Brakes
• Do
not interconnect the hydraulic brake system or vacuum
system of your vehicle with that of the trailer. This could
cause inadequate braking and possible personal injury.
• An electronically actuated trailer brake controller is required when towing a trailer with electronically actu -
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic brake
controller is not required.

• Trailer brakes are recommended for trailers over 1,000 lbs (453 kg) and required for trailers in excess of 2,000 lbs (907 kg).

WARNING!
• Do not connect trailer brakes to your vehicle's hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have brakes
when you need them and could have an accident.
• Towing any trailer will increase your stopping distance. When towing, you should allow for addi -
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an accident.

192 STARTING AND OPERATING
Towing Requirements — Trailer Lights And Wiring
Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.
NOTE:
Do not cut or splice wiring into the vehicle’s wiring harness.
The electrical connections are all complete to the vehicle but
you must mate the harness to a trailer connector. Refer to the
following illustrations.NOTE:
• Disconnect trailer wiring connector from the vehicle
before launching a boat (or any other device plugged into
vehicle’s electrical connect) into water.
• Be sure to reconnect once clear from water area.
Four-Pin Connector
CAUTION!
If the trailer weighs more than 1,000 lbs (453 kg) loaded,
it should have its own brakes and they should be of
adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal effort,
and longer stopping distances.

Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The trans-
mission controls include a drive strategy to avoid frequent
shifting when towing. However, if frequent shifting does
occur while in DRIVE, use the Electronic Range Select (ERS)
shift control to select a lower gear range.
NOTE:
Using a lower gear range while operating the vehicle under
heavy loading conditions will improve performance and
extend transmission life by reducing excessive shifting and
heat build up. This action will also provide better engine
braking.

194 STARTING AND OPERATING
Electronic Range Select (ERS)
• When using the ERS shift control, select the highest gearthat allows for adequate performance and avoids frequent
downshifts. For example, choose “5” if the desired speed
can be maintained. Choose “4” or “3” if needed to main -
tain the desired speed.
• To prevent excess heat generation, avoid continuous driving at high RPM. Reduce vehicle speed as necessary to
avoid extended driving at high RPM. Return to a higher
gear range or vehicle speed when grade and road condi -
tions allow.
Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the Speed Control, if you experience speed drops greater than 10 mph (16 km/h), disengage until you
can get back to cruising speed.
• Use Speed Control in flat terrain and with light loads to maximize fuel efficiency. Cooling System
To reduce potential for engine and transmission over
-
heating, take the following actions:
City Driving
• In city traffic — while stopped, place the transmission in NEUTRAL, but do not increase engine idle speed.
Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

196 STARTING AND OPERATING
DRIVING TIPS
Driving On Slippery Surfaces
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the front (driving)
wheels.Traction
When driving on wet or slushy roads, it is possible for a
wedge of water to build up between the tire and road
surface. This is hydroplaning and may cause partial or
complete loss of vehicle control and stopping ability. To
reduce this possibility, the following precautions should be
observed:
• Slow down during rainstorms or when the roads are
slushy.
• Slow down if the road has standing water or puddles.
• Replace the tires when tread wear indicators first become visible.
• Keep tires properly inflated.
• Maintain sufficient distance between your vehicle and the vehicle in front of you to avoid a collision in a sudden stop.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the front
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice, snow,
wet, mud, loose sand, etc.).
