2023 JEEP WRANGLER warning

STARTING AND OPERATING155
If ACC is set when the vehicle speed is below 20 mph
(32 km/h), the set speed will default to 20 mph
(32 km/h).
NOTE:Fixed Speed Cruise Control cannot be set below 20 mph
(32 km/h).
If either system is set when the vehicle speed is above
20 mph (32 km/h), the set speed shall be the current speed of the vehicle.
On vehicles equipped with a manual transmission, the
ACC system cannot be set when the vehicle speed is below
20 mph (32 km/h) or when the vehicle is in FIRST gear.
NOTE:
 Keeping your foot on the accelerator pedal can cause
the vehicle to continue to accelerate beyond the set
speed. If this occurs, the message “DRIVER OVERRIDE”
will display in the instrument cluster display.
 If you continue to accelerate beyond the set speed
while ACC is enabled, the system will not be controlling
the distance between your vehicle and the vehicle
ahead. The vehicle speed will only be determined by
the position of the accelerator pedal.

The Adaptive Cruise Control (ACC) on/off button is
pushed
 The Fixed Speed Cruise Control on/off button is pushed
 The ignition is placed in the OFF position
 4WD Low is engaged
To Resume
If there is a set speed in the memory, push the RES button
and then 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:

While in ACC mode, when the vehicle comes to a
complete stop longer than two seconds, the system will
cancel. The driver will have to apply the brakes to keep
the vehicle at a standstill.
 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.
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 condi -
tions could cause the vehicle to accelerate or deceler -
ate too sharply for safe operation. Failure to follow
these warnings can result in a collision and death or
serious personal injury.

156STARTING AND OPERATING
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 applies the brake down to a full stop
when following the vehicle in front. If your vehicle
follows the vehicle in front to a standstill, your vehicle
will release the brakes two seconds after coming to a
full stop.
 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 displays in the instrument cluster display.

Distance Settings

To increase the distance setting, push the Distance
Setting 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
Setting 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 displays the ACC Set
With Target Light. The system will then adjust 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 154
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

STARTING AND OPERATING157
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 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 A Stop (Automatic
Transmission Only)
In the event that the ACC system brings your vehicle to a
standstill while following a target vehicle, your vehicle will
resume motion without the need for any driver action if the
target vehicle starts moving within two seconds of your
vehicle coming to a standstill.
If the target vehicle does not start moving within two
seconds of your vehicle coming to a standstill, the ACC
with Stop system will cancel and the brakes will release. A
cancel message will display on the instrument cluster
display and produce a warning chime. Driver intervention
will be required at this moment.
While ACC with Stop is holding your vehicle at a standstill,
if the driver seatbelt is unbuckled or the driver door is
opened, the ACC with Stop system will cancel and the brakes will release. A cancel message will display on the
instrument cluster display and produce a warning chime.
Driver intervention will be required at this moment.
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 “ACC/FCW Unavailable Wipe Front Radar Sensor”
and the system will deactivate.
The “ACC/FCW Unavailable Wipe Front Radar Sensor”
message can sometimes be displayed while driving in
highly reflective areas (i.e. tunnels with reflective tiles, or
ice and snow). 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.
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.

23_JL_OM_EN_USC_t.book Page 157

158STARTING AND OPERATING
“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
display “ACC/FCW Limited Functionality Clean Front
Windshield” and the system will have degraded
performance.
The “ACC/FCW Limited Functionality Clean Front
Windshield” 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 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 displays
“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.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or
unexpectedly. The driver needs to stay alert and may need
to intervene. The following are examples of these types of
situations:
TOWING A TRAILER
Towing a trailer is not recommended when using ACC.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.

Offset Driving Condition Example

TURNS AND BENDS
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for
stability reasons, with no vehicle in front detected. Once
the vehicle is out of the curve the system will resume your
original set speed. This is a part of normal ACC system
functionality.
NOTE:On tight turns ACC performance may be limited.

23_JL_OM_EN_USC_t.book Page 158

160STARTING 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/bumper and a detected obstacle when backing up
(e.g. during a parking maneuver). For limitations of this
system and recommendations, see
Úpage 163.
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. If ParkSense is enabled at this gear selector
position, 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 is located within the
instrument cluster display Úpage 108. It provides visual
warnings to indicate the distance between the rear fascia/
bumper and the detected obstacle.
PARKSENSE DISPLAY
When the vehicle is in REVERSE, the instrument cluster
display will show 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 a single
arc moving closer to the vehicle and emit a fast sound
tone that will change from 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.

23_JL_OM_EN_USC_t.book Page 160

162STARTING AND OPERATING
The vehicle is close to the obstacle when the warning 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:
NOTE:ParkSense will reduce the volume of the radio, if on, when
the system is sounding an audio tone.
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 display
Úpage 108 will
show 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 show the “PARKSENSE OFF” message
for as long as the vehicle is in REVERSE (Not in 4WD Low). 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
remain on.
SERVICE THE PARKSENSE REAR PARK
A
SSIST SYSTEM
During vehicle start up, when the ParkSense Rear Park
Assist System has detected a faulted condition, the
instrument cluster display will actuate a single chime,
once per ignition cycle, and it will display the “PARKSENSE
UNAVAILABLE WIPE REAR SENSORS” or the “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 show the "PARKSENSE UNAVAILABLE
WIPE REAR SENSORS" or "PARKSENSE 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 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
obstruction 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
authorized dealer.

STARTING AND OPERATING163
CLEANING THE PARKSENSE SYSTEM
Clean the Rear Park Assist 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.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
 Ensure that the rear fascia/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.
 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) of 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.
PARKVIEW REAR BACK UP CAMERA
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.
Manual Activation Of The Rear View Camera

1. Press the Controls button located on the bottom of
the Uconnect display.

2. Press the Back Up Camera button to turn the Rear View Camera system on.
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 Park -
Sense.

(Continued)
When the vehicle is shifted out of REVERSE with Camera
delay turned off, the rear Camera mode is exited and the
previous screen appears again.
When the vehicle is shifted out of REVERSE with Camera
delay turned on, the rear Camera image will be displayed
for up to 10 seconds unless the vehicle speed exceeds
8 mph (13 km/h), the transmission is shifted into PARK,
the ignition is placed in the OFF position, or the
touchscreen X button to disable display of the Rear View
Camera image is pressed.
Whenever the Rear View Camera image is activated
through the Back Up Camera button in the Controls menu,
and the vehicle speed is greater than, or equal to, 8 mph
(13 km/h), a display timer for the image is initiated. The
image will continue to be displayed until the display timer
exceeds 10 seconds.
NOTE:

If the vehicle speed remains below 8 mph (13 km/h),
the Rear View Camera image will be displayed continu -
ously until deactivated via the touchscreen X button,
the transmission is shifted into PARK, or the ignition is
placed in the OFF position.
 The touchscreen X button to disable display of the
camera image is made available ONLY when the
vehicle is not in REVERSE.
When enabled, active guidelines are overlaid on the image
to illustrate the width of the vehicle and its projected back
up path based on the steering wheel position. A dashed
center line overlay indicates the center of the vehicle to
assist with parking or aligning to a hitch/receiver.
When enabled, fixed guidelines are overlaid on the image
to illustrate the width of the vehicle. Different colored zones indicate the distance to the rear of
the vehicle.
The following table shows the approximate distances for
each zone:
NOTE:If snow, ice, mud, or any foreign substance builds up on
the camera lens, clean the lens, rinse with water, and dry
with a soft cloth. Do not cover the lens.
TRAILCAM SYSTEM — IF EQUIPPED
Your vehicle may be equipped with a TrailCam that allows
you to you see an on-screen image of the front view of your
vehicle. The image will be displayed on the touchscreen
display along with a caution note “Check Entire
Surroundings” across the top of the screen.

WARNING!
Drivers must be careful when backing up even when
using the ParkView Rear Back Up Camera. Always
check carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles,
obstructions, or blind spots before backing up. You are
responsible for the safety of your surroundings and
must continue to pay attention while backing up.
Failure to do so can result in serious injury or death.
CAUTION!
 To avoid vehicle damage, ParkView should only be
used as a parking aid. The ParkView camera is
unable to view every obstacle or object in your drive
path.
To avoid vehicle damage, the vehicle must be driven
slowly when using ParkView to be able to stop in time
when an obstacle is seen. It is recommended that
the driver look frequently over his/her shoulder when
using ParkView.
