WARNING!
The Active Driving Assist (ADA) system is a
convenience system. It is not a substitute for
active driver involvement. It is always the driver’s
responsibility to be attentive of road traffic,
weather conditions, vehicle speed, distance to
the vehicle ahead, position in the lane compared
to other vehicles, and brake operation to ensure
safe operation of the vehicle under all road
conditions. Your complete attention is always
required while driving to maintain safe control of
your vehicle. Failure to follow these warnings can
result in a collision and death or serious
personal injury.
Some states and local laws may require hands
to be kept on the steering wheel at all times. For
vehicles equipped with the Hands-Free ADA
system, ONLY remove your hands from the
steering wheel if the Hands-Free system is
engaged, it is safe to do so, and it is permitted by
state and local laws.
You should turn off the Active Driving Assist
systems:
When driving in complex driving situations
(e.g. urban environments, construction zones,
etc.), adverse weather or low visibility condi -
tions (e.g. rain, snow, fog, sleet, dust), or
adverse road conditions (e.g. heavy traffic,
worn or missing lane markings, etc.).
When entering a highway on-ramp or exiting
an off-ramp.
When driving on roads that are icy, snow
covered, or slippery.
When driving during difficult or uncertain
conditions.
WARNING!

status indicator lights will turn off, Active Lane
Management will return to its previous state,
and ACC will disable or remain engaged pending
system conditions.
Hands-Free System Deactivation (If Equipped)
In addition to the deactivation conditions listed
above, the Hands-Free ADA system will also
deactivate in the following situations:
The system initiates a Stop-In-Lane maneuver to
stop the vehicle due to driver inattentiveness.
The Stop-In-Lane maneuver can be overridden
by placing hands on the steering wheel and
applying the accelerator or brake pedal. Refer to
“Indications On The Display” in the next section
for further information.
The vehicle is not receiving a clear cellular
signal for an extended period of time.

WARNING!

23_WL_OM_EN_USC_t.book Page 158

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.

23_WL_OM_EN_USC_t.book Page 160

162STARTING AND OPERATING
The vehicle is close to the obstacle when the instrument cluster display shows one flashing arc and sounds a continuous tone. The following chart shows the
warning alert operation when the system is detecting an obstacle:
NOTE:ParkSense will reduce the volume of the radio, if on, when the system is sounding an audio tone.

STARTING AND OPERATING163
Front Park Assist Audible Alerts
ParkSense will turn off the Front Park Assist
audible alert (chime) after approximately three
seconds when an obstacle has been detected, and
the vehicle is stationary.
Adjustable Chime Volume Settings
Front and rear chime volume settings can be
selected from the Uconnect system Ú page 204.
The chime volume settings include low, medium,
and high.
ParkSense will retain its last known configuration
state through ignition cycles.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within
the instrument cluster display Ú page 98. It
provides visual warnings to indicate the distance
between the rear fascia/bumper and/or front
fascia/bumper and the detected obstacle.
ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled
with the ParkSense switch located on the
switch panel above the Uconnect display.
When the ParkSense switch is pushed to enable
the system, the instrument cluster will display the
system state. When the ParkSense switch is pushed to disable
the system, the instrument cluster will display the
“PARKSENSE OFF” message for approximately two
seconds. When the gear selector is moved to
REVERSE and the system is disabled, the
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.

164STARTING AND OPERATING
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.
