Service The ParkSense® Rear Park Assist
System
During vehicle start up, when the ParkSense® Rear Park
Assist System has detected a faulted condition, the instru-
ment cluster will actuate a single chime, once per ignition
cycle, and it will display the “PARKSENSE UNAVAIL-
ABLE WIPE REAR SENSORS” or the “PARKSENSE UN-
AVAILABLE SERVICE REQUIRED” message. Refer to
“Electronic Vehicle Information Center (EVIC)” in “Under-
standing Your Instrument Panel” for further information.
When the shift lever/gear selector is moved to REVERSE
and the system has detected a faulted condition, the EVIC
will display thePARKSENSE UNAVAILABLE WIPE
REAR SENSORS orPARKSENSE UNAVAILABLE
SERVICE REQUIRED message for as long as the vehicle is
in REVERSE. Under this condition, ParkSense® will not
operate.
If “PARKSENSE UNAVAILABLE WIPE REAR SEN-
SORS” appears in the Electronic Vehicle Information
Center (EVIC) make sure the outer surface and the
underside of the rear 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 “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the EVIC, 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 dam-
age the sensors.

ParkSense® System Usage Precautions
NOTE:
•Ensure that the rear bumper is free of snow, ice, mud,
dirt and debris to keep the ParkSense® system oper-
ating properly.
• Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense®.
• When you turn ParkSense® OFF, the instrument clus-
ter 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 key.
• When you move the shift lever/gear selector to the
REVERSE position and ParkSense® is turned OFF, the
EVIC will display “PARKSENSE OFF” message 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 the fascia/bumper, or it could provide
a false indication that an obstacle is behind 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 in (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 EVIC.
240 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•On vehicles equipped with a tailgate, ParkSense®
should be disabled when the tailgate is in the lowered
or open position and the vehicle is in REVERSE. A
lowered tailgate could provide 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 recommended
that the driver looks over his/her shoulder when
using ParkSense®.
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 assem-
bly is 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 loudspeaker
sounds the continuous tone. Also, the sensors

could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
PARKSENSE® FRONT AND REAR PARK
ASSIST — IF EQUIPPED
The ParkSense® Park Assist system provides visual and
audible indications of the distance between the rear
and/or front fascia and a detected obstacle when backing
up or moving forward, e.g. during a parking maneuver.
If your vehicle is equipped with an Automatic Transmis-
sion, the vehicle brakes may be automatically applied
and released when performing a reverse parking maneu-
ver if the system detects a possible collision with an
obstacle. NOTE:
•
The driver can override the automatic braking func-
tion by pressing the gas pedal, turning ParkSense® off
via ParkSense® switch, or changing the gear while the
automatic brakes are being applied.
• Automatic brakes will not be available if ESC is not
available.
• 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 collid-
ing 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.
242 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

•The automatic braking function can be enabled/
disabled from the Customer-Programmable Features
section of the Uconnect® System.
• ParkSense® will retain its last known configuration
state for the automatic braking function through igni-
tion cycles.
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected ob-
stacles when backing up in REVERSE gear.
If your vehicle is equipped with a Manual Transmission,
the automatic braking function in REVERSE gear is not
available. NOTE:
•
The driver is always responsible for controlling the
vehicle.
• The system is provided 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.
Refer to ParkSense® System Usage Precautions for limi-
tations of this system and recommendations.
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 shift lever is in
REVERSE or DRIVE (NON-REVERSE for manual trans-
mission). If ParkSense® is enabled at one of these shift
lever positions, the system will remain active until the
vehicle speed is increased to approximately 7 mph
(11 km/h) or above. When in REVERSE and above the
system’s operating speed, a warning will appear in the
EVIC indicating the vehicle speed is too fast. 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 in (30 cm) up to 79 in
(200 cm) from the rear fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.NOTE:
If your vehicle is equipped with the ParkSense®
Active Park Assist system, six sensors will be located in
the rear fascia/bumper. Refer to the ParkSense® Active
Park Assist System section for further information.
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 in (30 cm) up to 47 in
(120 cm) from the front fascia/bumper in the horizontal
direction, depending on the location, type and orienta-
tion of the obstacle.ParkSense® Warning Display
The ParkSense® Warning screen will only be displayed if
Sound and Display is selected from the Customer -
Programmable Features section of the Uconnect® Sys-
tem. Refer to Uconnect® Settings” in “Understanding

The ParkSense® Warning screen is located within the
Electronic Vehicle Information Center (EVIC). It provides
visual warnings to indicate the distance between the rear
fascia/bumper and/or front fascia/bumper and the de-
tected obstacle. Refer to “Electronic Vehicle Information
Center (EVIC)/Settings” in Understanding Your Instru-
ment Panel” for further information.
ParkSense® Display
Rear Park Assist
When the vehicle is in REVERSE, the EVIC will display
the park assist ready system status.
The system will indicate a detected obstacle by showing
a single arc in one or more regions based on the obstacle’s
distance and location relative to the vehicle.If an obstacle is detected in the center rear region, the
display will show a single solid arc in the center rear
region and will produce a one-half second tone. As the
vehicle moves closer to the obstacle, the display will
show the single arc moving closer to the vehicle and the
sound tone will change from slow, to fast, to continuous.
If an obstacle is detected in the left and/or right rear
region, the display will show a single flashing arc in the
left and/or right rear region and will produce a fast
sound tone. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to the
vehicle and the tone will change from fast to continuous.
