2020 JEEP WRANGLER UNLIMITED sensor

STARTING AND OPERATING
162
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 requires service, the
ParkSense switch LED will blink momen-
tarily, and then the LED will be on.
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 instru -
ment cluster display will read “PARK -
SENSE OFF.” Furthermore, once you turn
ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition.
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 indica-
tion 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.
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 atten -
tion 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 contin -
uous 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.

PARKSENSE FRONT AND
REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Front & Rear Park Assist
system provides visual and audible indica-
tions 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). Refer to “ParkSense
System Usage Precautions” in this section
for limitations of this system and recommen -
dations. ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is placed in the ON/
RUN position.
ParkSense can be active only when the gear
selector is in REVERSE or DRIVE. If Park
-
Sense 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. If
the gear selector is in REVERSE, a 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 direction,
depending on the location, type and orienta -
tion 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 obsta
-
cles 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 orienta -
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen is located
within the instrument cluster display. It
provides visual warnings to indicate 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 Instru -
ment Panel” for further information.
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 one or more
regions based on the obstacle’s distance and
location relative to 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.

STARTING AND OPERATING
166
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 the “PARKSENSE UNAVAILABLE
WIPE REAR SENSORS”, “PARKSENSE
UNAVAILABLE WIPE FRONT SENSORS” or
“PARKSENSE UNAVAILABLE SERVICE
REQUIRED” message. When the gear
selector is moved to REVERSE and the
system has detected a faulted condition, the
instrument cluster display will display a car
graphic with an overlay saying “Wipe Off” or
“Service”. Under this condition, ParkSense
will not operate. Refer to “Instrument Cluster
Display” in “Getting To Know Your Instru-
ment Panel” for further information.
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 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. In washing stations, clean
sensors quickly keeping the vapor jet/high
pressure washing nozzles at least 4 inches
(10 cm) from the sensors. Do not scratch or
poke the sensors. Otherwise, you could
damage the sensors.
ParkSense System Usage Precautions
NOTE:
Ensure that the front and rear bumpers 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 System off, the
instrument cluster display will show the
“ParkSense Off” message for two seconds.
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 System
is turned off, the instrument cluster
display will show the “ParkSense Off”
message. This message will be displayed
for as long as the vehicle is in REVERSE.
NOTE:
The “ParkSense Off” message will not
display while the vehicle is in 4LO position.
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 obstacles such as
bicycle carriers, trailer hitches, etc. are

placed within 30 cm from the rear fascia/
bumper. Failure to do so can result in the
system misinterpreting a close obstacle as
a sensor problem, causing the “PARK
-
SENSE UNAVAILABLE SERVICE
REQUIRED” message to appear in the
instrument cluster display.
ParkSense should be disabled when the
swing gate is in the open position. An open
swing gate could provide a false indication
that an obstacle is behind the vehicle.
PARKVIEW REAR BACK UP
CAMERA — IF EQUIPPED
The ParkView Rear Back Up Camera allows
you to see an on-screen image of the rear
surroundings of your vehicle whenever the
gear selector is put into REVERSE. The
image will be displayed in the touchscreen
display along with a caution note to “check
entire surroundings” across the top of the
screen. After five seconds this note will
disappear. The ParkView camera is located
on the rear of the vehicle in the center of the
spare tire. 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 atten -
tion 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 contin -
uous 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
