gear selector positions, the system will remain active until
the vehicle speed is increased to approximately 7 mph
(11 km/h) or above. A display warning will appear in the
instrument cluster display indicating the vehicle is above
ParkSense operating speed. The system will become active
again if the vehicle speed is decreased to speeds less than
approximately 6 mph (9 km/h).
ParkSense Sensors
The four ParkSense sensors, located in the rear fascia/
bumper, monitor the area behind the vehicle that is within
the sensors’ field of view. The sensors can detect obstacles
from approximately 12 inches (30 cm) up to 79 inches

direction, depending on the location, type and orientation
of the obstacle.
The six ParkSense sensors, located in the front fascia/
bumper, monitor the area in front of the vehicle that is
within the sensors’ field of view. The sensors can detect
obstacles from approximately 12 inches (30 cm) up to 47
inches (120 cm) from the front fascia/bumper in the
horizontal direction, depending on the location, type and
orientation of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be displayed if
Sound and Display is selected from the Customer - Pro-
grammable Features section of the Uconnect System. Refer

330 STARTING AND OPERATING

ParkSense Display
When the vehicle is in REVERSE and an obstacle has been
detected, the warning display will turn on indicating the
system status.
The system will indicate a detected obstacle by showing a
single arc in the left and/or right 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.

Service The ParkSense Park Assist System
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 thePARKSENSE UNAVAILABLE WIPE REAR
SENSORS, PARKSENSE UNAVAILABLE WIPE FRONT
SENSORS,orthePARKSENSE UNAVAILABLE SERVICE
REQUIRED message for five seconds. When the gear
selector is moved to Reverse and the system has detected a faulted condition, the instrument cluster display will dis-
play a
PARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS, PARKSENSE UNAVAILABLE WIPE FRONT SEN-
SORS orPARKSENSE UNAVAILABLE SERVICE
REQUIRED pop up message for five seconds. After five
seconds, a vehicle graphic will be displayed with UN-
AVAILABLE 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 function-
ing 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 dis-
played for as long as the vehicle is in REVERSE. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
If PARKSENSE UNAVAILABLE WIPE REAR SENSORS
or PARKSENSE UNAVAILABLE WIPE FRONT SEN-
SORS 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
6
STARTING AND OPERATING 337

snow, ice, mud, dirt or other obstruction and then cycle the
ignition. If the message continues to appear see an autho-
rized dealer.
If thePARKSENSE UNAVAILABLE SERVICE RE-
QUIRED message appears in the instrument cluster dis-
play, 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. Otherwise, you could damage the
sensors.
ParkSense System Usage Precautions
NOTE:
• Ensure that the front and rear bumper 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
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) from 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.
