154STARTING AND OPERATING
PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear and
the front fascia/bumper and a detected obstacle when
backing up or moving forward (e.g. during a parking
maneuver). The vehicle brakes may be automatically
applied and released when performing a reverse parking
maneuver if the system detects a possible collision with
an obstacle.
NOTE:
The driver can disable the automatic braking function
by turning ParkSense off via the ParkSense switch. The
driver can also override automatic braking by changing
the gear or by pressing the gas pedal over 90% of its
capacity during the braking event.
 Automatic brakes are not available if the vehicle is in
4WD Low.
 Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
 The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
 The automatic braking function may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
 The automatic braking function can be enabled/
disabled from the Customer Programmable Features
section of the Uconnect system. 
ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles.
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected
obstacles when backing up in REVERSE gear.
NOTE:
 The system is designed to assist the driver and not to
substitute the driver.
 The driver must stay in full control of the vehicle's
acceleration and braking and is responsible for the
vehicle's movements.
For limitations of this system and recommendations, see
Úpage 159.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of
these gear selector positions, the system will remain
active until the vehicle speed is increased to
approximately 7 mph (11 km/h) or above. The system will
become active again if the vehicle speed is decreased to
speeds less than approximately 6 mph (9 km/h). A display
warning will appear in the instrument cluster display if the
vehicle is in REVERSE and the speed exceeds 7 mph
(11 km/h).
PARKSENSE SENSORS
The four ParkSense sensors located in the rear fascia/
bumper, and the six ParkSense sensors located in the
front fascia/bumper, monitor the area in front and behind
the vehicle that is within the sensors’ field of view. The
front sensors detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from the front fascia/bumper. The rear sensors can detect obstacles
from approximately 12 inches (30 cm) up to 79 inches
(200 cm) from the rear fascia/bumper. These distances
depend on the location, type and orientation of the
obstacle in the horizontal direction.
NOTE:If the vehicle is equipped with ParkSense Active Park
Assist, there will be six ParkSense sensors located in the
rear fascia/bumper.
PARKSENSE DISPLAY
The warning display will turn on indicating the system
status when the vehicle is in REVERSE or when the vehicle
is in DRIVE and an obstacle has been detected.
The system will indicate a detected obstacle by showing a
single arc in the left and/or right front or rear regions
based on the object’s distance and location relative to the
vehicle.
If an object is detected in the left and/or right rear region,
the display will show a single arc in the left and/or right
rear region and the system will produce a tone. As the
vehicle moves closer to the object, the display will show
the single arc moving closer to the vehicle and the tone will
change from a single 1/2 second tone to slow, to fast, to
continuous.

158STARTING AND OPERATING
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
 Ensure that the front and rear fascias/bumpers are
free of snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
 Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.
 When you turn ParkSense off, the instrument cluster
will display “PARKSENSE OFF.” Furthermore, once you
turn ParkSense off, it remains off until you turn it on
again, even if you cycle the ignition.
 When you move the gear selector to the REVERSE posi -
tion and ParkSense is turned off, the instrument
cluster will display “PARKSENSE OFF” for as long as the
vehicle is in REVERSE.
 ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
 Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper. 
Use the ParkSense switch to turn the ParkSense
system off if objects such as bicycle carriers, trailer
hitches, etc. are placed within 12 inches (30 cm) of the
rear fascia/bumper. Failure to do so can result in the
system misinterpreting a close object as a sensor
problem, causing the “PARKSENSE UNAVAILABLE
SERVICE REQUIRED” message to be displayed in the
instrument cluster.
 ParkSense should be disabled when the liftgate is in
the open position. An opened liftgate could provide a
false indication that an obstacle is behind the vehicle.
SIDE DISTANCE WARNING SYSTEM —
I
F EQUIPPED
The Side Distance Warning system detects the presence
of side obstacles near the vehicle using the parking
sensors located in the front and rear fascia/bumpers.
Side Distance Warning Display
The Side Distance Warning screen will only be displayed if
this feature is enabled within Uconnect Settings
Úpage 197.
The system warns the driver with an acoustic signal and,
when enabled, with visual indications on the instrument
cluster display.
WARNING!
 Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind your
vehicle, look behind you, and be sure to check for
pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up. You are respon -
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
 Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly be
disconnected 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 vehicle sounds the contin -
uous 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.

23_WS_OM_EN_USC_t.book Page 158

STARTING AND OPERATING159
When the vehicle is in DRIVE, the Side Distance Warning
volume/chime will match the Front ParkSense volume
and chime type.
When the vehicle is in REVERSE, the Side Distance
Warning volume/chime will match the Rear ParkSense
volume and chime type.
NOTE:Parksense will reduce the volume of the radio if on when
the system is sounding an audible tone. An audible tone
will only sound if a collision is possible.
Activation/Deactivation
The system can operate only after driving a short distance
and if the vehicle speed is between 0 and 7 mph
(0 and 11 km/h). The system can be activated/
deactivated via the Settings menu of the Uconnect
system. If the ParkSense System is deactivated via the
ParkSense hard switch then the Side Distance Warning
system will automatically be deactivated.
Message on the display for Side Distance Warning
feature:
“Wipe Sensors” — This message is displayed in the case of
a failure of the Side Distance Warning system sensors.
Free the bumpers of any obstacles, ensure that the front
and rear fascia/bumper are free of snow, ice, mud, dirt
and debris to keep the ParkSense system operating
properly.
“System Not Available” — This message is displayed if the
Side Distance Warning system is not available. The failed
operation of the system might be due to the insufficient
voltage from the battery or other failures on the electrical
system. Contact an authorized dealer as soon as possible
to have the electrical system checked.
ParkSense Usage Precautions
Some conditions may influence the performance of the
Side Distance Warning system:
NOTE:
Ensure that the front and rear fascia/bumper are free
of snow, ice, mud, dirt and debris to keep the Park -
Sense system operating properly.
 Construction equipment, large trucks, and other vibra -
tions could affect the performance of ParkSense.
 When you turn ParkSense off, the message to appear
in the instrument cluster display will read “PARKSENSE
OFF.” Furthermore, once you turn ParkSense off, it
remains off until you turn it on again, even if you cycle
the ignition.
 ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
 Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
 The presence of a tow hook without a trailer may inter -
fere with the correct operation of the parking sensors.
Before using the ParkSense system, it is recom -
mended to remove the removable tow hook ball
assembly and any attachments from the vehicle when
it is not used for towing operations.

(Continued)
PARKSENSE ACTIVE PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers. The system works by identifying a proper
parking space, providing audible/visual instructions, and
controlling the steering wheel only, or the accelerator,
gear selector, brakes, and the steering wheel (if equipped
with the Fully Automated system). Depending on the
driver's parking maneuver selection, the ParkSense Active
Park Assist system is capable of maneuvering a vehicle
into a parallel or a perpendicular parking space on either
side (i.e., driver side or passenger side).
Two types of ParkSense Active Park Assist systems are
available:
Semi-Automatic ParkSense Active Park Assist
 ParkSense Automated Parking system Semi-Automatic ParkSense Active Park Assist —
If Equipped
The Semi-Automatic system detects parking spaces, and
controls the steering wheel only. The driver maintains
control of the accelerator, gear selector and brakes.
ParkSense Automated Parking — If Equipped
The Fully Automated system detects parking spaces, and
controls the accelerator, gear selector, brakes, and
steering wheel. In this mode, the system also provides
obstacle detection by providing visual and audible
warnings and automatic braking to avoid a collision.
If your vehicle is equipped with the Fully Automated
system, you can switch between Semi-Automatic and Fully
Automated mode in the Uconnect Settings
Úpage 197.
NOTE:

The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required.
 The system is designed to assist the driver and not to
substitute the driver.
 During a Semi-Automatic or Fully Automated
maneuver, if the driver touches the steering wheel
after being instructed to remove their hands from the
steering wheel, the system will cancel, and the driver
will be required to manually complete the parking
maneuver.
WARNING!
Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind your
vehicle, look behind you, and be sure to check for
pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up. You are respon -
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
 Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly be
disconnected 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 vehicle sounds the contin -
uous 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.

STARTING AND OPERATING163
(Continued)
The system will then instruct the driver to remove hands
from the steering wheel and feet from the pedals. This
screen will be shown for a minimum of two seconds, or
until the driver releases the brake pedal.
When the parking sequence is initiated by the driver after
the previously described conditions are met, the Uconnect
system will display a Top View along with either a rear
camera view (if the vehicle is placed in REVERSE) or a
forward camera view (if the vehicle is placed in DRIVE).
The Top View will have integrated ParkSense arcs in the
image at the front and rear of the vehicle. The arcs will
change color from yellow to red corresponding the
distance zones to the oncoming object.
The system will then perform the parking maneuver. Once
the maneuver is complete, the vehicle will automatically
shift into PARK.
The system will display a “Complete!” message and
instruct the driver to release the Active Park Assist switch.
Once the Active Park Assist switch is released, a chime will
sound and the LED on the switch will turn off. After
approximately five seconds, the previous Uconnect screen
will display.
NOTE:

It is the driver's responsibility to use the brake and stop
the vehicle. The driver should check their surroundings
and be prepared to stop the vehicle either when
instructed to, or when driver intervention is required.
 When the system instructs the driver to remove their
hands from the steering wheel, the driver should check
their surroundings and begin to back up slowly.
 The system will cancel the maneuver if the vehicle
speed exceeds 28 mph (40 km/h) during active
steering guidance into the parking space. The system
will provide a warning to the driver at 28 mph
(40 km/h) that tells them to slow down. The driver is
then responsible for completing the maneuver if the
system is canceled.
 If the system is canceled during the maneuver for any
reason, the driver must take control of the vehicle.
WARNING!
Drivers must be careful when performing parallel or
perpendicular parking maneuvers even when using
the ParkSense Active Park Assist system. Always
check carefully behind and in front of your vehicle,
look behind and in front of you, and be sure to check
for pedestrians, animals, other vehicles, obstruc -
tions, and blind spots before backing up and moving
forward. You are responsible for safety and must
continue to pay attention to your surroundings.
Failure to do so can result in serious injury or death.
 Before using the ParkSense Active Park Assist
system, it is strongly recommended that the ball
mount and hitch ball assembly be disconnected from
the vehicle when the vehicle is not used for towing.
Failure to do so can result in injury or damage to vehi -
cles or obstacles because the hitch ball will be much
closer to the obstacle than the rear fascia/bumper
when the vehicle sounds the continuous tone. Also,

166STARTING AND OPERATING
Once active steering begins, a camera image will appear
in the Uconnect display with instructions that will display
for the duration of the maneuver.
The system may then instruct the driver to wait for steering
to complete before then instructing to check the vehicle’s
surroundings, and move backward.

Move Backward

Several more gear shifts (DRIVE and REVERSE) while
keeping hands off of the steering wheel will be instructed
to the driver while checking the vehicle’s surroundings
before completing the parking maneuver.
When the vehicle is in the parking position, the maneuver
is complete and the driver will be instructed to check the
vehicle's parking position, then shift the vehicle into PARK.
The message “Complete! Check Parking Position” will be
displayed momentarily.

178STARTING AND OPERATING
VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
PAYLOAD
The payload of a vehicle is defined as the allowable weight
a vehicle can carry, including the weight of the driver, all
passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles, or suspension
components sometimes specified by purchasers for
increased durability, do not necessarily increase the
vehicle's GVWR or GAWR.
TIRE SIZE
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire size
listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
CURB WEIGHT
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
LOADING
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to ensure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should then
be determined separately to be sure that the load is
properly distributed over the front and rear axles.
Weighing the vehicle may show that the GAWR of either
the front or rear axles has been exceeded but the total
load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to
front as appropriate until the specified weight limitations
are met. Store the heavier items down low and be sure
that the weight is distributed equally. Stow all loose items
securely before driving.
NOTE:

Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles and
the way the brakes operate.
 Air suspension vehicle may limit off-road heights if
loaded beyond recommended values for vehicle GVWR
and GAWR.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
WARNING!
Do not load your vehicle any heavier than the GVWR or
the maximum front and rear GAWR. If you do, parts on
your vehicle can break, or it can change the way your
vehicle handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

23_WS_OM_EN_USC_t.book Page 178

STARTING AND OPERATING179
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 178.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its "loaded and
ready for operation" condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle and
trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 178.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
If equipped, the electronic TSC recognizes a swaying
trailer and automatically applies individual wheel brakes
and/or reduces engine power to attempt to eliminate the
trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some
other connecting point of the vehicle. These kinds of
hitches are used to tow small and medium sized trailers.
Weight-Distributing Hitch
A Weight-Distributing Hitch system works by applying
leverage through spring (load) bars. They are typically
used for heavier loads to distribute trailer tongue weight to
the tow vehicle's front axle and the trailer axle(s). When
used in accordance with the manufacturer's directions, it
provides for a more level ride, offering more consistent
steering and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway control
also dampens sway caused by traffic and crosswinds and
contributes positively to tow vehicle and trailer stability.
Trailer sway control and a weight-distributing (load
equalizing) hitch are recommended for heavier Tongue
Weights (TW) and may be required depending on vehicle
and trailer configuration/loading to comply with Gross Axle
Weight Rating (GAWR) requirements.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg) or
more, it is recommended to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.
WARNING!
An improperly adjusted Weight-Distributing Hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
 Weight-Distributing Hitch systems may not be
compatible with surge brake couplers. Consult with
your hitch and trailer manufacturer or a reputable
Recreational Vehicle dealer for additional
information.
