If the "PARKSENSE UNAVAILABLE SERVICE
REQUIRED" message appears in the instrument
cluster display, see an authorized dealer.
CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear fascia/bumper
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Jackhammers, large trucks, and other vibra -
tions could affect the performance of
ParkSense.
When you turn ParkSense off, the instrument
cluster will display “PARKSENSE OFF.” Further -
more, 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 position 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.
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 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 ParkSense, it is strongly recom -
mended 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
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.

STARTING AND OPERATING165
SIDE DISTANCE WARNING SYSTEM
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 204.
The system warns the driver with an acoustic
signal and, when enabled, with visual indications
on the instrument cluster display. 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.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
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom
-
mended that the driver looks over his/her
shoulder when using ParkSense.

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 ParkSense system operating properly.
Construction equipment, large trucks, and other
vibrations 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 key.
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
interfere with the correct operation of the
parking sensors. Before using the ParkSense system, it is recommended to remove the
removable tow hook ball assembly and any
attachments from the vehicle when it is not
used for towing operations.

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 by identifying a
proper parking space, providing audible/visual
instructions, and controlling the steering wheel.
The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver
maintains control of the accelerator, gear selector
and brakes. 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).
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 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 ParkSense, it is strongly recom
-
mended 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
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
ParkSense in order to be able to stop in time
when an obstacle is detected. It is recom -
mended that the driver looks over his/her
shoulder when using ParkSense.

23_WL_OM_EN_USC_t.book Page 166

168STARTING AND OPERATING
NOTE:If the vehicle is driven above approximately
15 mph (25 km/h), the instrument cluster display
will instruct the driver to slow down. If the vehicle
is driven above approximately 18 mph (30 km/h),
the system will cancel. The driver must then reac -
tivate the system by pushing the ParkSense Active
Park Assist switch.
When pushed, the LED on the ParkSense Active
Park Assist switch will blink momentarily, and then
the LED will turn off if any of the preceding
conditions are not present.
If the vehicle is in any other gear than DRIVE, and
an objected is detected, the system will default to
Parallel Park Exit. A prompt will appear in the radio
screen, and the driver will need to select “Yes” or
“No” for a Parallel Park Exit maneuver. Any other
conditions will result in a default to a Parallel
Parking maneuver.
PARALLEL/PERPENDICULAR PARKING
S
PACE ASSISTANCE OPERATION
When the ParkSense Active Park Assist system is
enabled, you can select between Parallel,
Perpendicular, and Parallel Park Exit maneuvers in
the Uconnect system.
Choose Parking Maneuver Below

NOTE:
When searching for a parking space, use the
turn signal indicator to select which side of the
vehicle you want to perform the parking
maneuver. The ParkSense Active Park Assist
system will automatically search for a parking
space on the passenger's side of the vehicle if
the turn signal is not activated.
The driver needs to make sure that the selected
parking space for the maneuver remains free
and clear of any obstructions (e.g. pedestrians,
bicycles, etc.).
The driver is responsible to ensure that the
selected parking space is suitable for the
maneuver and free/clear of anything that may
be overhanging or protruding into the parking
space (e.g., ladders, tailgates, etc. from
surrounding objects/vehicles).
When searching for a parking space, the driver
should drive as parallel or perpendicular
(depending on the type of maneuver) to other
vehicles as possible.
The feature will only indicate the last detected
parking space (e.g., if passing multiple available
parking spaces, the system will only indicate the
last detected parking space for the maneuver).
While the vehicle is in DRIVE, there will be a full
screen image in the Uconnect display. If the
driver shifts to REVERSE while searching for a
parking space, a camera image will appear in
the Uconnect display with a “Shift To Drive”
message.
When an available parking space has been found,
and the vehicle is not in position, you will be
instructed to move forward to position the vehicle
for a perpendicular or parallel parking sequence
(depending on the type of maneuver being
performed).

STARTING AND OPERATING171
Selection Of The Maneuver Side
Use the direction indicators to choose the direction
that you want to perform the maneuver. Use the
right arrow indicator to perform the maneuver to
the right side and use the left arrow indicator to
perform the maneuver to the left.
During the maneuver, the system instructs the
driver to shift to REVERSE, and operate the turn
signal in the direction you want to exit. Let go of the
steering wheel and use the brake or accelerator
pedals as instructed, while the system handles the
steering automatically for exiting the parking
space. If the driver continues to carry out a
voluntary or involuntary action on the steering
wheel during the exit maneuver (touching or
holding the steering wheel to prevent its
movement), the maneuver will be interrupted.

Shift To Reverse Then Move Backward Shift To Drive Then Move Forward

End Of Maneuver
The semi-automatic maneuver ends when the
display shows the message of a completed
maneuver. At the end of the maneuver, the system
gives back the vehicle control to the driver.
ACTIVE LANE MANAGEMENT SYSTEM —
IF EQUIPPED
ACTIVE LANE MANAGEMENT OPERATION
The Active Lane Management (ALM) system uses a
forward facing camera to detect lane markings or
road edges and to measure vehicle position within
the lane boundaries. It also uses the Blind Spot
Monitoring (BSM) sensors to detect vehicles in
adjacent lanes while the driver is preparing to
change lanes. The system is operational at speeds above 37 mph
(60 km/h) and below 112 mph (180 km/h).
When both lane markings are detected, and the
vehicle approaches (or crosses) the lane marking
with no turn signal applied, and the blind spot zone
is not occupied, the ALM system provides warnings
to prompt the driver to remain within the lane
boundaries. These warnings include a visual
warning in the instrument cluster along with
steering assist torque (if configured in Uconnect
Settings).
If the driver crosses the lane marking, the system
will either guide the vehicle back to the center of
the lane, provide a vibration in the steering wheel,
or both, depending on radio settings.
When both lane markings are detected, and the
driver uses the turn signal to indicate a lane
change, and a vehicle is detected in the BSM zone
on that side of the vehicle, the ALM system
provides a warning in the form of steering assist
and/or steering vibration (depending on radio
settings) to guide the vehicle back to the center of
the lane.NOTE:
The system will suppress visual warnings,
steering vibration (if selected in radio settings),
and steering assistance (if selected in radio
settings) when the driver activates the turn
signal, the blind spot zone is clear of vehicles,
and a lane change is occurring.

RECOMMENDED DISTRIBUTION HITCH
ADJUSTMENT

1. Verify that the vehicle is at the Normal Ride
Height.

NOTE:The vehicle must remain in the engine run position
with all doors closed while attaching a trailer for
proper leveling of the air suspension system.
2. Position the vehicle to be ready to connect to the trailer (do not connect the trailer). 3. For vehicles equipped with Quadra-Lift air
suspension, use the touchscreen radio
settings to enable Tire/Jack mode. Tire/Jack
mode will be canceled and the procedure must
be restarted if the vehicle is driven at speeds
above 5mph (8 km/h).
4. Measure the height from the top of the front wheel opening on the fender to ground; this is
height H1.

Measuring Height (H)

5. Attach the trailer to the vehicle without the weight distribution bars connected.
6. Measure the height from the top of the front wheel opening on the fender to the ground;
this is height H2. 7. Install and adjust the tension in the weight
distributing bars per the manufacturer’s
recommendations so that the height of the
front fender is approximately (H2-H1)/2+H1
(about 1/2 the difference between H2 and H1
above Normal Ride Height [H1]).
8. Use the touchscreen radio settings and switch off Tire/Jack mode. Make sure the truck
returns to Normal Ride Height. Perform a
visual inspection of the trailer and
weight-distributing hitch to confirm the
manufacturers’ recommendations have been
met.
9. The vehicle can now be driven.
An improperly adjusted weight-distributing
hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight-distributing 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.
