STARTING AND OPERATING

Adjustable Chime Volume Settings

Rear chime volume settings can be selected from the
Customer-Programmable Features section of the Uconnect
System, refer to “Uconnect Settings” in “Multimedia” for
further information.

The chime volume settings include low, medium, and high.
The factory default volume setting is medium.

ParkSense will retain its last known configuration state
through ignition cycles.

Enabling And Disabling ParkSense

ParkSense can be enabled and disabled with the ParkSense
switch.

When the ParkSense switch is pushed to disable
the system, the instrument cluster will display
the “PARKSENSE OFF” message for approxi-
mately five seconds. Refer to “Instrument Clus-

ter Display” in “Getting To Know Your Instrument Panel”
for further information. When the gear selector is moved to
REVERSE and the system is disabled, the instrument
cluster display will display the “PARKSENSE OFF” mes-
sage for as long as the vehicle is in REVERSE.

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 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 “In-
strument Cluster Display”. When the gear selector is
moved to REVERSE and the system has detected a faulted
condition, the instrument cluster display will display the

⬙PARKSENSE UNAVAILABLE WIPE REAR SENSORS⬙ or

⬙PARKSENSE UNAVAILABLE SERVICE REQUIRED⬙ mes-
sage for as long as the vehicle is in REVERSE. Under this
condition, ParkSense will not operate.

If “PARKSENSE UNAVAILABLE WIPE REAR SENSORS”
appears in the instrument cluster display make sure the
outer surface and the underside of the rear fascia/bumper

STARTING AND OPERATING

291

is clean and clear of snow, ice, mud, dirt or other obstruc-
tion and then cycle the ignition. If the message continues to
appear, see an authorized dealer.

If “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
appears in the instrument cluster display, see an autho-
rized 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 rear bumper is 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 display will display “PARKSENSE OFF” mes-
sage 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 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 display.

• ParkSense should be disabled when the liftgate is in the

open position and the vehicle is in REVERSE. An open

292

STARTING AND OPERATING

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 respon-
sible 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 recommended

that the ball mount and hitch ball assembly 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 con-
tinuous 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 recommended that the
driver looks over his/her shoulder when using
ParkSense.

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 transmission, the
vehicle brakes may be automatically applied and released
when performing a reverse parking maneuver if the sys-
tem detects a possible collision with an obstacle.

STARTING AND OPERATING

293

NOTE:
• The driver can override the automatic braking function

by pressing the gas pedal, turning ParkSense off via
ParkSense switch, or changing the gear while the auto-
matic 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 colliding
with a detected obstacle.

• The automatic braking function will not be available if

vehicle is in 4LO transfer case mode.

• 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 Programmable Features
section of the Uconnect System.

• ParkSense will retain its last known configuration 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 ob-
stacles when backing up in REVERSE gear.

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 limita-
tions 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 gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of these
gear selector positions, the system will remain active until

294

STARTING AND OPERATING

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 (200
cm) from the rear fascia/bumper in the horizontal direc-
tion, 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
to

⬙Uconnect Settings” in “Multimedia” for further infor-

mation.

The ParkSense Warning screen is located within the instru-
ment cluster display. It provides visual warnings to indi-
cate the distance between the rear fascia/bumper and/or
front fascia/bumper and the detected obstacle. Refer to
“Instrument Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.

STARTING AND OPERATING

295

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.
