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,
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!
The ParkSense Active Park Assist system 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 the
ParkSense Active Park Assist system 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 the ParkSense Active Park
Assist system.

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.
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.
It is the driver’s responsibility to use the brake and
accelerator during the Semi-Automatic parking
maneuver.
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 ParkSense Active Park Assist system will allow a
maximum of eight shifts between DRIVE and REVERSE.
If the maneuver cannot be completed within eight
shifts, the system will cancel and the instrument
cluster display will instruct the driver to complete the
maneuver manually.
The system will cancel the maneuver if the vehicle
speed exceeds 18 mph (30 km/h) during active
steering guidance into the parking space. The system
will provide a warning to the driver at 15 mph
(25 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!

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.
