2023 JEEP CHEROKEE warning

STARTING AND OPERATING95
To Resume
If there is a set speed in memory, push the RES (resume)
button and remove your foot from the accelerator pedal.
The instrument cluster display will show the last set
speed.
Resume can be used at any speed above 20 mph
(32 km/h) when only Fixed Speed Cruise Control is being
used.
Resume can be used at any speed above 0 mph (0 km/h)
when ACC is active.
NOTE:
If your vehicle stays at a standstill for longer than two
seconds, then the driver will either have to push the
RES (resume) button, or apply the accelerator pedal to
reengage the Adaptive Cruise Control (ACC) to the
existing set speed.
 ACC cannot be resumed if there is a stationary vehicle
in front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
After setting a speed, you can increase the set speed by
pushing the SET (+) button, or decrease speed by pushing
the SET (-) button.
U.S. Speed (mph)
 Pushing the SET (+), or SET (-) button once will result in
a 1 mph speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 mph.
 If the button is continually pushed, the set speed will
continue to adjust in 5 mph increments until the button
is released. The new set speed is reflected in the instru -
ment cluster display.
Metric Speed (km/h)
 Pushing the SET (+), or SET (-) button once will result in
a 1 km/h speed adjustment. Each subsequent tap of
the button results in an adjustment of 1 km/h.
 If the button is continually pushed, the set speed will
continue to adjust in 10 km/h increments until the
button is released. The new set speed is reflected in
the instrument cluster display.
NOTE:When you override and push the SET (+) button or SET (-)
buttons, the new set speed will be the current speed of the
vehicle. When ACC Is Active

When you use the SET (-) button to decelerate, if the
engine’s braking power does not slow the vehicle suffi -
ciently to reach the set speed, the brake system will
automatically slow the vehicle.
 The ACC system decelerates the vehicle to a full stop
when following a vehicle in front. If your vehicle follows
the vehicle in front to a standstill, after two seconds the
driver will either have to push the RES (resume) button,
or apply the accelerator pedal to reengage the ACC to
the existing set speed.
 The ACC system maintains set speed when driving
uphill and downhill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill. This
is normal operation and necessary to maintain set
speed. When driving uphill and downhill, the ACC
system will cancel if the braking temperature exceeds
normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle ahead. This
distance setting appears in the instrument cluster display.WARNING!
The Resume function should only be used if traffic and
road conditions permit. Resuming a set speed that is
too high or too low for prevailing traffic and road
conditions could cause the vehicle to accelerate or
decelerate too sharply for safe operation. Failure to
follow these warnings can result in a collision and death
or serious personal injury.

96STARTING AND OPERATING

Distance Settings

To increase the distance setting, push the Distance
Increase button and release. Each time the button is
pushed, the distance setting increases by one bar (longer).
To decrease the distance setting, push the Distance
Decrease button and release. Each time the button is
pushed, the distance setting decreases by one bar
(shorter).
If there is no vehicle ahead, the vehicle will maintain the
set speed. If a slower moving vehicle is detected in the
same lane, the instrument cluster display will show the
ACC Set With Target Detected Indicator Light, and the
system will adjust the vehicle speed automatically to
maintain the distance setting, regardless of the set speed. The vehicle will then maintain the set distance until:

The vehicle ahead accelerates to a speed above the
set speed.
 The vehicle ahead moves out of your lane or view of the
sensor.
 The distance setting is changed.
 The system disengages
Úpage 94.
The maximum braking applied by ACC is limited; however,
the driver can always apply the brakes manually, if
necessary.
NOTE:The brake lights will illuminate whenever the ACC system
applies the brakes.
A Proximity Warning will alert the driver if ACC predicts that
its maximum braking level is not sufficient to maintain the
set distance. If this occurs, a visual alert “BRAKE!” will
flash in the instrument cluster display and a chime will
sound while ACC continues to apply its maximum braking
capacity.
NOTE:The “BRAKE!” screen in the instrument cluster display is a
warning for the driver to take action and does not neces -
sarily mean that the Forward Collision Warning system is
applying the brakes autonomously.
Overtake Aid
When driving with Adaptive Cruise Control (ACC) engaged
and following a vehicle, the system will provide an
additional acceleration up to the ACC set speed to assist
in passing the vehicle. This additional acceleration is
triggered when the driver utilizes the left turn signal and
will only be active when passing on the left hand side.
ACC Operation At Stop
In the event that the ACC system brings your vehicle to a
standstill while following the vehicle in front, if the vehicle
in front starts moving within two seconds of your vehicle
coming to a standstill, your vehicle will resume motion
without the need for any driver action.
If the vehicle in front does not start moving within two
seconds of your vehicle coming to a standstill, the driver
will either have to push the RES (resume) button, or apply
the accelerator pedal to reengage the ACC to the existing
set speed.
NOTE:After the ACC system holds your vehicle at a standstill for
approximately three consecutive minutes, the parking
brake will be activated, and the ACC system will be
canceled.
While ACC is holding your vehicle at a standstill, if the
driver seat belt is unbuckled or the driver door is opened,
the parking brake will be activated, and the ACC system
will be canceled.
1 — Longest Distance Setting (Four Bars)
2 — Medium Distance Setting (Two Bars)
3 — Long Distance Setting (Three Bars)
4 — Short Distance Setting (One Bar)
WARNING!
When the ACC system is resumed, the driver must
ensure that there are no pedestrians, vehicles or
objects in the path of the vehicle. Failure to follow these
warnings can result in a collision and death or serious
personal injury.

STARTING AND OPERATING97
Display Warnings And Maintenance
“WIPE FRONT RADAR SENSOR IN FRONT OF
VEHICLE” WARNING
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning will display and a chime will sound when
conditions temporarily limit system performance.
This most often occurs at times of poor visibility, such as
in snow or heavy rain. The ACC system may also become
temporarily blinded due to obstructions, such as mud, dirt
or ice. In these cases, the instrument cluster display will
display this message and the system will deactivate.
This message can sometimes be displayed while driving in
highly reflective areas (i.e. ice and snow, or tunnels with
reflective tiles). The ACC system will recover after the
vehicle has left these areas. Under rare conditions, when
the radar is not tracking any vehicles or objects in its path
this warning may temporarily occur.
NOTE:If the “ACC/FCW Unavailable Wipe Front Radar Sensor”
warning is active, Fixed Speed Cruise Control is still
available.
If weather conditions are not a factor, the driver should
examine the sensor. It may require cleaning or removal of
an obstruction. The sensor is located in the center of the
vehicle behind the lower grille.
To keep the ACC system operating properly, it is important
to note the following maintenance items:
Always keep the sensor clean. Carefully wipe the
sensor lens with a soft cloth. Be cautious not to
damage the sensor lens. 
Do not remove any screws from the sensor. Doing so
could cause an ACC system malfunction or failure and
require a sensor realignment.
 If the sensor or front end of the vehicle is damaged due
to a collision, see an authorized dealer for service.
 Do not attach or install any accessories near the
sensor, including transparent material or aftermarket
grilles. Doing so could cause an ACC system failure or
malfunction.
When the condition that deactivated the system is no
longer present, the system will return to the “Adaptive
Cruise Control Off” state and will resume function by
simply reactivating it.
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 an
authorized dealer.
 Installing a snow plow, front-end protector, an after -
market grille or modifying the grille is not recom -
mended. Doing so may block the sensor and inhibit
ACC/FCW operation.
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC/FCW Limited Functionality Clean Front
Windshield” warning will display, and a chime will sound
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.
This 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 rearview 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 Wind
-
shield” 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 an 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 temporarily
unavailable. If this occurs, try activating ACC again later,
following an ignition cycle. If the problem persists, see an
authorized dealer.

23_KL_OM_EN_USC_t.book Page 97

100STARTING AND OPERATING
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected
obstacles when backing up in REVERSE gear.
NOTE:
The system is designed 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.
For limitations of this system, precautions, and
recommendations, see
Úpage 103.
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. The system will
become active again if the vehicle speed is decreased to
less than approximately 6 mph (9 km/h). A display
warning will appear in the instrument cluster display if the
vehicle is in REVERSE and the speed exceeds 7 mph
(11 km/h).PARKSENSE SENSORS
The six ParkSense sensors (four when vehicle is not
equipped with front sensors), located in the rear fascia/
bumper, and the six ParkSense sensors located in the
front fascia/bumper, monitor the area in front and behind
the vehicle that is within the sensors’ field of view. The
front sensors detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from the front
fascia/bumper. The rear sensors can detect obstacles
from approximately 12 inches (30 cm) up to 79 inches
(200 cm) from the rear fascia/bumper. These distances
depend on the location, type and orientation of the
obstacle in the horizontal direction.
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.

23_KL_OM_EN_USC_t.book Page 100

102STARTING AND OPERATING
The vehicle is close to the obstacle when the instrument cluster display shows one flashing arc and sounds a continuous tone. The following chart shows the warning alert operation
when the system is detecting an obstacle:

obstacle.
ENABLING AND DISABLING PARKSENSE
ParkSense can be enabled and disabled with
the ParkSense switch located below the
Uconnect display.
When the ParkSense switch is pushed to disable the
system, the instrument cluster will display the
“PARKSENSE OFF” message for approximately five
seconds. When the gear selector is moved to REVERSE and the system is disabled, the instrument cluster display
will display the “PARKSENSE OFF” message for as long as
the vehicle is in REVERSE.
NOTE:When ParkSense is disabled and the gear selector is
moved to the DRIVE position, no warning message will be
displayed.
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 PARK ASSIST
S
YSTEM
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 the "PARKSENSE 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 display a "PARKSENSE UNAVAILABLE WIPE
REAR SENSORS", "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" or "PARKSENSE UNAVAILABLE SERVICE
REQUIRED" pop-up message for five seconds. After five
seconds, a vehicle graphic will be displayed with
"UNAVAILABLE" 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 functioning 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 displayed
for as long as the vehicle is in REVERSE.
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
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.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
 Ensure that the front and rear fascia/bumper are free
of snow, ice, mud, dirt and debris to keep the Park -
Sense system operating properly.
 Jackhammers, large trucks, and other vibrations could
affect the performance of ParkSense.

104STARTING AND OPERATING
(Continued)

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 posi -
tion 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 WIPE REAR
SENSORS” message to be displayed in the instrument
cluster. It may also result is false braking events.
 ParkSense should be disabled when the liftgate is in
the open position. An opened liftgate could provide a
false indication that an obstacle is behind the vehicle.
SIDE DISTANCE WARNING SYSTEM
The Side Distance Warning system detects the presence
of side obstacles near the vehicle using the parking
sensors located in the front and rear bumpers.
Side Distance Warning Display
The Side Distance Warning screen will only be displayed if
“Sound and Display” is selected within the Uconnect
system
Úpage 126.
The system warns the driver with an acoustic signal and,
when enabled, with visual indications on the instrument
panel 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 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 be
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 vehicle 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.
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 Park -
Sense 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.

feature:
“Wipe Sensors” — This message is displayed in the case of
a failure of the Side Distance Warning system sensors.
Free the bumpers of any obstacles, ensure that the front
and rear fascia/bumper are free of snow, ice, mud, dirt
and debris to keep the ParkSense system operating
properly.
“System Not Available” — This message is displayed if the
Side Distance Warning system is not available. The failed
operation of the system might be due to the insufficient voltage from the battery or other failures on the electrical
system. Contact an authorized dealer as soon as possible
to have the electrical system checked.
ParkSense Usage Precautions
Some conditions may influence the performance of the
Side Distance Warning system:
NOTE:

Ensure that the front and rear fascia/bumper are free
of snow, ice, mud, dirt and debris to keep the Park -
Sense system operating properly.
 Construction equipment, large trucks, and other vibra -
tions 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 key.
 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.
 The presence of a tow hook without a trailer may inter -
fere with the correct operation of the parking sensors.
Before using the ParkSense system, it is recom -
mended to remove the removable tow hook ball assembly and any attachments from the vehicle when
it is not used for towing operations.
