PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and if equipped, 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 Program -
mable Features section of the Uconnect system.
ParkSense will retain its last known configura -
tion 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.

160STARTING AND OPERATING
For limitations of this system and
recommendations, see Ú page 166.
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 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.

instrument cluster display will display the
“PARKSENSE OFF” message for as long as the
vehicle is in REVERSE.
NOTE:When ParkSense is disabled and the gear selector
is moved to the DRIVE position, no warning
message will be displayed.
The ParkSense switch LED will be on when
ParkSense is disabled or requires service. The
ParkSense switch LED will be off when the system
is enabled. If the ParkSense switch is pushed, and
the system requires service, the ParkSense switch
LED will blink momentarily, and then the LED will
be on.
SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start-up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single chime,
once per ignition cycle, and it will display a pop-up.
The pop-up will include up to two faults. Possible
fault messages are "PARKSENSE UNAVAILABLE
WIPE REAR SENSORS", "PARKSENSE
UNAVAILABLE WIPE FRONT SENSORS", or "PARKSENSE UNAVAILABLE SERVICE REQUIRED.”
The pop-up message will display for five seconds.

When the gear selector is moved to REVERSE and
the system has detected a faulted condition, the
instrument cluster display will display a
"PARKSENSE UNAVAILABLE WIPE REAR SENSORS",
"PARKSENSE UNAVAILABLE WIPE FRONT SENSORS"
or "PARKSENSE UNAVAILABLE SERVICE REQUIRED"
pop-up message for five seconds. After five seconds,
a vehicle graphic will be displayed with
"UNAVAILABLE" at either the front or rear sensor
location depending on where the fault is detected.
The system will continue to provide arc alerts for the
side that is functioning properly. These arc alerts will
interrupt the "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS", or "PARKSENSE UNAVAILABLE
SERVICE REQUIRED" messages if an object is
detected within the five second pop-up duration. The
vehicle graphic will remain displayed for as long as
the vehicle is in REVERSE.

If "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" appears in the instrument
cluster display make sure the outer surface and
the underside of the rear fascia/bumper and/or
front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle
the ignition. If the message continues to appear
see an authorized dealer.

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.

23_WL_OM_EN_USC_t.book Page 164

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

STARTING AND OPERATING167
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 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.
The system may not work in all conditions (e.g.
environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space
that has surfaces that will absorb the ultrasonic
sensor waves).
New vehicles from the dealership must have at
least 30 miles (48 km) accumulated before the
ParkSense Active Park Assist system is fully cali -
brated and performs accurately. This is due to
the system’s dynamic vehicle calibration to
improve the performance of the feature. The
system will also continuously perform the
dynamic vehicle calibration to account for differ -
ences such as over or under inflated tires and
new tires.
ENABLING AND DISABLING THE

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).
