2017 JEEP CHEROKEE sensor

NOTE:
•
If the “ACC/FCW Unavailable Wipe Front Radar Sensor”
message occurs frequently (e.g. more than once on every
trip) without any snow, rain, mud, or other obstruction,
have the radar sensor realigned at your authorized dealer.
•Installing a snow plow, front-end protector, an aftermarket
grille or modifying the grille is not recommended. Doing
so may block the sensor and inhibit ACC/FCW operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” warning will display and also a chime will indicate
when conditions temporarily limit system performance. This
most often occurs at times of poor visibility, such as in snow
or heavy rain and fog. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt,
or ice on windshield and fog on the inside of glass. In these
cases, the instrument cluster display will read “ACC/FCW
Limited Functionality Clean Front Windshield” and the
system will have degraded performance.
The “ACC/FCW Limited Functionality Clean Front Wind-
shield” message can sometimes be displayed while driving
in adverse weather conditions. The ACC/FCW system will
recover after the vehicle has left these areas. Under rare conditions, when the camera is not tracking any vehicles or
objects in its path this warning may temporarily occur.
If weather conditions are not a factor, the driver should
examine the windshield and the camera located on the
back side of the inside rear view mirror. They may require
cleaning or removal of an obstruction.
When the condition that created limited functionality is no
longer present, the system will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently (e.g. more
than once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward facing
camera inspected at your authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the instrument cluster display
reads “ACC/FCW Unavailable Service Required” or
“Cruise/FCW Unavailable Service Required”, there may
be an internal system fault or a temporary malfunction that
limits ACC functionality. Although the vehicle is still
drivable under normal conditions, ACC will be temporar-
ily unavailable. If this occurs, try activating ACC again
later, following an ignition cycle. If the problem persists,
see your authorized dealer.
306 STARTING AND OPERATING

PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. Refer to “ParkSense System Usage
Precautions” in this section for limitations 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. If ParkSense is enabled at this gear selector posi-
tion, 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 within the instrument cluster display
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 inches (30 cm) up to 79 inches (200 cm) from
the rear 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
toUconnect 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 the
detected obstacle. Refer to “Instrument Cluster Display”
for further information.
314 STARTING AND OPERATING

Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with the ParkSense
switch, located on the switch panel below the Uconnect
display.
When the ParkSense switch is pushed to disable the
system, the instrument cluster display will show the
“PARKSENSE OFF” message for approximately five sec-
onds. Refer to “Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further information.
When the gear selector is moved to REVERSE and thesystem is disabled, the instrument cluster display will
show the “PARKSENSE OFF” message 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 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 display will actuate a single chime, once per
ignition cycle, and it will display the “PARKSENSE UN-
AVAILABLE WIPE REAR SENSORS” or the “PARKSENSE
UNAVAILABLE SERVICE REQUIRED” message. Refer to
“Instrument Cluster Display”. When the gear selector is
moved to REVERSE and the system has detected a faulted
condition, the instrument cluster display will show 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.
ParkSense Switch
318 STARTING AND OPERATING

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
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
•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
display will read “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 show a “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.
6
STARTING AND OPERATING 319

•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 appear in the instrument clus-
ter display.
• ParkSense should be disabled when the liftgate is in the
open position and the vehicle is in REVERSE. An open
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.
(Continued)
WARNING! (Continued)
•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.

320 STARTING AND OPERATING

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 the
vehicle speed is increased to approximately 7 mph (11 km/h)
or above. When in REVERSE and above the system’s operat-
ing speed, a warning will appear in the instrument cluster
display 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 inches (30 cm) up to 79 inches (200 cm) from
the rear fascia/bumper in the horizontal direction, depending
on the location, type and orientation of the obstacle.
