JEEP CHEROKEE 2023 Owners Manual

STARTING AND OPERATING89
NOTE:
Even if the power steering assistance is no longer oper -
ational, it is still possible to steer the vehicle. Under
these conditions there will be a substantial increase in
steering effort, especially at low speeds and during
parking maneuvers.
 If the condition persists, see an authorized dealer for
service.
STOP/START SYSTEM
The Stop/Start system was designed to reduce fuel
consumption. The system will stop the engine
automatically during a vehicle stop if the required
conditions are met. Releasing the brake pedal or pressing
the accelerator pedal will automatically restart the engine.
This vehicle has been upgraded with a heavy-duty battery,
starter, as well as other engine parts, to handle the
additional engine starts.
AUTOSTOP MODE
The Stop/Start feature is enabled after every normal
customer engine start. At that time, the system will go into
STOP/START READY.
To Activate The Autostop Mode, The Following Must Occur:
The system must be in STOP/START READY state. A
“STOP/START READY” message will be displayed in the
instrument cluster display within the Stop/Start
section
Úpage 63.
 The vehicle must be completely stopped.
 The gear selector must be in a forward gear and the
brake pedal pressed. The engine will shut down, the tachometer will move to the
zero position, and the Stop/Start indicator light will
illuminate indicating you are in Autostop. Customer
settings will be maintained upon return to an
engine-running condition.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check many
safety and comfort conditions to see if they are fulfilled.
Detailed information about the operation of the Stop/Start
system may be viewed in the instrument cluster display
Stop/Start Screen. In the following situations, the engine
will not stop:
 Driver’s seat belt is not buckled
 Driver’s door is not closed
 Battery temperature is too warm or cold

 Steering angle is beyond threshold
It may be possible for the vehicle to be driven several
times without the Stop/Start system going into a STOP/
START READY state under more extreme conditions of the
items listed previously.TO START THE ENGINE WHILE IN
A
UTOSTOP MODE
While in a forward gear, the engine will start when the
brake pedal is released or the accelerator pedal is
pressed. The transmission will automatically re-engage
upon engine restart.

will appear in the instrument cluster display
Úpage 68.
If the “SERVICE STOP/START SYSTEM” message appears
in the instrument cluster display, have the system
checked by an authorized dealer.
CRUISE CONTROL SYSTEMS — IF EQUIPPED
Your vehicle may be equipped with the Cruise Control
system, or the Adaptive Cruise Control (ACC) system:
 Cruise Control will keep your vehicle at a constant
preset speed.
 Adaptive Cruise Control (ACC) will adjust the vehicle
speed up to the preset speed to maintain a distance
with the vehicle ahead.
NOTE:
In vehicles equipped with ACC, if ACC is not enabled,
Fixed Speed Cruise Control will not detect vehicles
directly ahead of you. Always be aware of the feature
selected. 
Only one Cruise Control feature can operate at a time.
For example, if Fixed Speed Cruise Control is enabled,
Adaptive Cruise Control will be unavailable, and vice
versa.
CRUISE CONTROL
When engaged, the Cruise Control takes over accelerator
operations at speeds greater than 20 mph (32 km/h).
The Cruise Control buttons are located on the right side of
the steering wheel.

Cruise Control Buttons

1 — On/Off
2 — CANC/Cancel
3 — SET (+)/Accel
4 — RES/Resume
5 — SET (-)/Decel

23_KL_OM_EN_USC_t.book Page 90

STARTING AND OPERATING91
NOTE:Do not place the gear selector in NEUTRAL when Cruise
Control is activated. Doing so will disengage the system.
To Activate
Push the on/off button to activate the Cruise Control. The
cruise indicator light in the instrument cluster display will
illuminate. To turn the system off, push the on/off button
a second time. The cruise indicator light will turn off. The
system should be turned off when not in use.
To Set A Desired Speed
Turn the Cruise Control on. When the vehicle has reached
the desired speed, push and release the SET (+) or SET (-)
button. Release the accelerator and the vehicle will
operate at the selected speed. Once a speed has been
set, a message “CRUISE CONTROL SET TO MPH (km/h)”
will appear indicating the set speed. A cruise control
indicator light, along with set speed will also appear and
stay on in the instrument cluster when the speed is set.
To Vary The Speed Setting
To Increase Or Decrease The Set Speed
When the Cruise Control is set, you can increase 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 until the button is released, then the
new set speed will be established.
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 until the button is released, then the
new set speed will be established.
To Accelerate For Passing
While the Cruise Control is set, press the accelerator to
pass as you would normally. When the pedal is released,
the vehicle will return to the set speed.
USING CRUISE CONTROL ON HILLS
The transmission may downshift on hills to maintain the
vehicle set speed.
The Cruise Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Cruise Control.
To Resume Speed
To resume a previously set speed, push the RES button
and release. Resume can be used at any speed above
20 mph (32 km/h).
WARNING!
Cruise Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could
go too fast for the conditions, and you could lose control
and have an accident. Do not use Cruise Control in
heavy traffic or on roads that are winding, icy, snow-
covered or slippery.
WARNING!
Leaving the Cruise Control system on when not in use is
dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always leave the system
off when you are not using it.
WARNING!

92STARTING AND OPERATING
(Continued)
To Deactivate
A tap on the brake pedal, pushing the CANC button, or
normal brake pressure will deactivate the Cruise Control
system without erasing the set speed from memory.
The following conditions will also deactivate the Cruise
Control without erasing the set speed from memory:
Vehicle parking brake is applied
 Stability event occurs
 Gear selector is moved out of DRIVE
 Engine overspeed occurs
Pushing the on/off button or placing the ignition in the OFF
position, will erase the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions. The Cruise
Control function performs differently
Úpage 90.
ACC will allow you to keep Cruise Control engaged in light
to moderate traffic conditions without the constant need
to reset your Cruise Control. ACC utilizes a radar sensor
and a forward facing camera designed to detect a vehicle
directly ahead of you.
NOTE:
 If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead. 
Any chassis/suspension or tire size modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
 Fixed Speed Cruise Control will not detect vehicles
directly ahead of you. Always be aware of the feature
selected
Úpage 262.
WARNING!
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. It is always the driver’s responsibility to be
attentive of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead and,
most importantly, brake operation to ensure safe
operation of the vehicle under all road conditions.
Your complete attention is always required while
driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a colli -
sion and death or serious personal injury.
 The ACC system:
 Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
 Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.
 Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
 Will bring the vehicle to a complete stop and
hold the vehicle in the stop position for approxi -
mately three minutes when following a vehicle
ahead. If the vehicle ahead does not start
moving within three minutes, the parking brake
will be activated, and the ACC system will be
canceled.
 You should switch off the ACC system:
 When driving in fog, heavy rain, heavy snow,
sleet, heavy traffic, and complex driving situa-
tions (i.e., in highway construction zones).
 When entering a turn lane or highway off-ramp;
when driving on roads that are winding, icy,
snow-covered, slippery, or have steep uphill or
downhill slopes.
 When towing a trailer up or down steep slopes.
 When circumstances do not allow safe driving at
a constant speed.

You could lose control and have a collision. Always leave
the system off when you are not using it.
WARNING!
In Fixed Speed Cruise Control mode, the system will not
react to vehicles ahead. In addition, the proximity
warning does not activate and no alarm will sound even
if you are too close to the vehicle ahead since neither
the presence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected. Be sure to
maintain a safe distance between your vehicle and the
vehicle ahead. Always be aware which mode is
selected.

23_KL_OM_EN_USC_t.book Page 94

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.

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_KL_OM_EN_USC_t.book Page 96

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.

98STARTING AND OPERATING
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 increase or decrease the vehicle speed for stability,
with no vehicle ahead 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.
USING ACC ON HILLS
ACC performance may be limited when driving on hills.
ACC may not detect a vehicle in your lane depending on
the speed, vehicle load, traffic conditions, and the
steepness of the hill.

ACC Hill Example

LANE CHANGING
ACC may not detect a vehicle until it is completely in the
lane in which you are traveling. In the following lane
changing example, ACC has not yet detected the vehicle
changing lanes and it may not detect the vehicle until it's
too late for the ACC system to take action. ACC may not
detect a vehicle until it is completely in the lane. There
may not be sufficient distance to the lane-changing
vehicle. Always be attentive and ready to apply the brakes
if necessary.

Lane Changing Example
