2023 JEEP CHEROKEE parking brake

86STARTING AND OPERATING

2-Speed 4x4 Switch (with Rear Lock)

The Four-Wheel Drive is fully automatic in the normal
driving mode. The Selec-Terrain buttons provide three
selectable mode positions:
4WD LOW
 REAR LOCK (If Equipped)
 N (NEUTRAL)
When additional traction is required, the 4WD LOW range
position can be used to provide an additional gear
reduction, which allows for increased torque to be
delivered to both the front and rear wheels. 4WD LOW is
intended for loose, slippery road surfaces only. Driving in
4WD LOW on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline components.
When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the normal
driving mode at a given road speed. Take care not to
overspeed the engine, and do not exceed 25 mph
(40 km/h).
Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel. Any difference will adversely affect shifting and cause
damage to the driveline components.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
SHIFT POSITIONS
For additional information on the appropriate use of each
4WD system mode position, see the information below:
N (NEUTRAL)
This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle
Úpage 120.
4WD LOW
This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slippery
road surfaces only. Do not exceed 25 mph (40 km/h).
NOTE:For further information on the various positions and their
intended uses Úpage 88.
SHIFTING PROCEDURES
Shifting Into 4WD LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h), the
ignition in the ON/RUN position and the engine running,
shift the transmission into NEUTRAL (N), and push the
4WD LOW button once. The 4WD LOW indicator light in the
instrument cluster will begin to flash and remain on solid
when the shift is complete.

4WD LOW Button

NOTE:
If shift conditions/interlocks are not met, a message will
flash from the instrument cluster display with instructions
on how to complete the requested shift
Úpage 63.
WARNING!
You or others could be injured or killed if you leave the
vehicle unattended with the power transfer unit in the N
(NEUTRAL) position without first fully engaging the
parking brake. The N (NEUTRAL) position disengages
both the front and rear driveshafts from the powertrain
and will allow the vehicle to roll, even if the
transmission is in PARK. The parking brake should
always be applied when the driver is not in the vehicle,
unless the vehicle is otherwise secured (for example,
when attached to the tow vehicle).

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
 Battery charge is low
 The vehicle is on a steep grade
 Cabin heating or cooling is in process and an accept -
able cabin temperature has not been achieved
 HVAC is set to full defrost mode at a high blower speed
 HVAC is set to MAX A/C
 Engine has not reached normal operating temperature
 The transmission is not in a forward or reverse gear
 Hood is open
 Brake pedal is not pressed with sufficient pressure with
vehicle in DRIVE (D) position
 Accelerator pedal input 
Engine temperature is too high
 5 mph (8 km/h) threshold has not been achieved from
previous Autostop
 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.
Conditions That Will Cause The Engine To Start
Automatically While In Autostop Mode:
 The transmission gear selector is moved out of DRIVE,
except in the PARK position
 To maintain cabin temperature comfort
 HVAC is set to full defrost mode
 HVAC system temperature or fan speed is manually
adjusted
 Battery voltage drops too low
 Stop/Start OFF switch is pushed
 A Stop/Start system error occurs
 Steering wheel is turned beyond threshold

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.

WARNING!
Leaving the Adaptive Cruise Control (ACC) 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 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.

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.

23_KL_OM_EN_USC_t.book Page 96

STARTING AND OPERATING99
NARROW VEHICLES
Some narrow vehicles traveling near the outer edges of
the lane or edging into the lane are not detected until they
have moved fully into the lane. There may not be sufficient
distance to the vehicle ahead.

Narrow Vehicle Example

STATIONARY OBJECTS AND VEHICLES
ACC does not react to stationary objects or vehicles. For
example, ACC will not react in situations where the vehicle
you are following exits your lane and the vehicle ahead is
stopped in your lane. It will consider this stopped vehicle a
stationary object as it did not previously detect movement
from it. Always be attentive and ready to apply the brakes
if necessary.

Stationary Object And Stationary Vehicle Example

PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear, and
if equipped, the front fascia/bumper and a detected
obstacle when backing up or moving forward (e.g. during a
parking maneuver). The vehicle brakes may be
automatically applied and released when performing a
reverse parking maneuver if the system detects a possible
collision with an obstacle.
NOTE:
The driver can disable the automatic braking function
by turning ParkSense off via the ParkSense switch. The
driver can also override automatic braking by changing
the gear or by pressing the gas pedal over 90% of its
capacity during the braking event.
 Automatic brakes are not available if the vehicle is in
4WD Low.
 Automatic brakes will not be available if there is a
faulted condition detected with the ParkSense Park
Assist system or the Braking System Module.
 The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
 The automatic braking function may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
 The automatic braking function can be enabled/
disabled from the Customer Programmable Features
section of the Uconnect system.
 ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles.

106STARTING AND OPERATING
PARKSENSE ACTIVE PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Active Park Assist system is intended to
assist the driver during parallel, perpendicular, and
parallel park exit maneuvers by identifying a proper
parking space, providing audible/visual instructions, and
controlling the steering wheel. The ParkSense Active Park
Assist system is defined as “semi-automatic” since the
driver maintains control of the accelerator, gear selector
and brakes. Depending on the driver's parking maneuver
selection, the ParkSense Active Park Assist system is
capable of maneuvering a vehicle into a parallel or a
perpendicular parking space on either side (i.e., driver
side or passenger side), as well as exiting a parallel
parking space.
NOTE:
The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required during a parking maneuver.
 The system is designed to assist the driver and not to
substitute the driver. 
During a semi-automatic maneuver, if the driver
touches the steering wheel after being instructed to
remove their hands from the steering wheel, the
system will cancel, and the driver will be required to
manually complete the parking maneuver.
 The system may not work in all conditions (e.g. environ -
mental conditions such as heavy rain, snow, etc., or if
searching for a parking space that has surfaces that
will absorb the ultrasonic sensor waves).
 New vehicles from the dealer must have at least
30 miles (48 km) accumulated before the ParkSense
Active Park Assist system is fully calibrated and
performs accurately. This is due to the system’s
dynamic vehicle calibration to improve the perfor -
mance of the feature. The system will also continuously
perform the dynamic vehicle calibration to account for
differences such as over or under inflated tires and
new tires.
ENABLING AND DISABLING THE
P
ARKSENSE ACTIVE PARK ASSIST
S
YSTEM
The ParkSense Active Park Assist system can
be enabled and disabled with the ParkSense
Active Park Assist switch, located on the switch
panel below the Uconnect display.
To enable or disable the ParkSense Active Park Assist
system, push the ParkSense Active Park Assist switch
once (LED turns on). Pushing the switch a second time will
disable the system (LED turns off). The ParkSense Active Park Assist system will turn off
automatically for any of the following conditions:

Parking maneuver is completed
 Vehicle speed is greater than 18 mph (30 km/h) when
searching for a parking space
 Vehicle speed is greater than 5 mph (7 km/h) during
active steering guidance into the parking space
 Steering wheel is touched during active steering guid -
ance into the parking space
 ParkSense switch is pushed
 Driver's door is opened
 Rear liftgate is opened
 Electronic Stability Control/Anti-Lock Braking System
intervention
NOTE:The ParkSense Active Park Assist system allows a
maximum number of shifts between DRIVE and REVERSE.
If the maneuver cannot be completed within the maximum
amount of shifts, the system will cancel and the
instrument cluster display will instruct the driver to
complete the maneuver manually.
The ParkSense Active Park Assist system will only operate
and search for a parking space when the following
conditions are present:
Gear selector is in DRIVE.
 Ignition is in the RUN position.
 ParkSense Active Park Assist switch is activated.
 Driver's door is closed.
 Rear liftgate is closed.

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.
CAUTION!
