service JEEP CHEROKEE 2023 Owner's Manual

76GETTING TO KNOW YOUR INSTRUMENT PANEL
Your vehicle has a simple ignition actuated test, which you
can use prior to going to the test station. To check if your
vehicle's OBD II system is ready, you must do the following:

1. Cycle the ignition switch to the ON position, but do
not crank or start the engine.

NOTE:If you crank or start the engine, you will have to start this
test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the Malfunction Indicator Light
symbol come on as part of a normal bulb check. 3. Approximately 15 seconds later, one of two things will
happen:
 The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that
your vehicle's OBD II system is not ready and you
should not proceed to the I/M station.
 The MIL will not flash at all and will remain fully illu -
minated until you place the ignition in the off posi -
tion or start the engine. This means that your
vehicle's OBD II system is ready and you can
proceed to the I/M station. If your OBD II system is
not ready, you should see an
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,
you may need to do nothing more than drive your vehicle
as you normally would in order for your OBD II system to
update. A recheck with the previously mentioned test
routine may then indicate that the system is now ready.

EPB Switch

To apply the parking brake manually, pull up on the EPB
switch momentarily. You may hear a sound from the back
of the vehicle while the parking brake engages. Once the
parking brake is fully engaged, the red Brake Warning
Light in the instrument cluster and an indicator on the
switch will illuminate. If your foot is on the brake pedal
while you apply the parking brake, you may notice a small
amount of brake pedal movement. The parking brake can
be applied even when the ignition switch is OFF but the
Brake Warning Light will not illuminate. The parking brake
can only be released when the ignition is in the ON/RUN
position.
NOTE:The EPB Warning Light will illuminate if the EPB switch is
held for longer than 90 seconds in either the released or
applied position. The light will extinguish upon releasing
the switch.
If the Auto Park Brake feature is enabled, the parking
brake will automatically engage whenever the
transmission is placed into PARK, while the ignition is turned OFF. If your foot is on the brake pedal, you may
notice a small amount of brake pedal movement while the
parking brake is engaging.
The parking brake will release automatically when the
ignition is ON, the transmission is in DRIVE (D) or REVERSE
(R) and the driver seat belt is buckled.
To release the parking brake manually, the ignition switch
must be in the ON/RUN position. Put your foot on the
brake pedal, then push the EPB switch down momentarily.
You may hear a sound from the back of the vehicle while
the parking brake disengages. You may also notice a small
amount of movement in the brake pedal. Once the parking
brake is fully disengaged, the Brake Warning Light in the
instrument cluster and the LED indicator on the switch will
extinguish.
NOTE:When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away from
the curb on an uphill grade. Apply the parking brake before
placing the gear selector in PARK, otherwise the load on
the transmission locking mechanism may make it difficult
to move the gear selector out of PARK.
WARNING!

Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.
 When exiting the vehicle, always turn the ignition off,
secure the key fob and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a
number of reasons. A child or others could be seri -
ously or fatally injured. Children should be warned
not to touch the parking brake, brake pedal or the
gear selector.
 Do not leave the key fob in or near the vehicle, or in
a location accessible to children, and do not leave a
vehicle equipped with Keyless Enter ‘n Go™ in the
ACC or ON/RUN position. A child could operate power
windows, other controls, or move the vehicle.
 Be sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and
a collision.
 Always fully apply the parking brake when leaving
your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the Brake System Warning Light remains on with the
parking brake released, a brake system malfunction is
indicated. Have the brake system serviced by an
authorized dealer immediately.
WARNING!

23_KL_OM_EN_USC_t.book Page 79

80STARTING AND OPERATING
If exceptional circumstances should make it necessary to
engage the parking brake while the vehicle is in motion,
maintain upward pressure on the EPB switch for as long as
engagement is desired. The Brake Warning Light will
illuminate, and a continuous chime will sound. The rear
stop lamps will also be illuminated automatically while the
vehicle remains in motion.
To disengage the parking brake while the vehicle is in
motion, release the EPB switch. If the vehicle is brought to
a complete stop using the parking brake, when the vehicle
reaches approximately 3 mph (5 km/h) the parking brake
will remain engaged.
In the unlikely event of a malfunction of the EPB system, a
yellow EPB Warning Light will illuminate. This may be
accompanied by the Brake Warning Light flashing. In this
event, urgent service of the EPB system is required. Do not
rely on the parking brake to hold the vehicle stationary.
Auto Park Brake
The EPB can be programmed to be applied automatically
whenever the vehicle is at a standstill and the automatic
transmission is placed in PARK, whenever the ignition is turned OFF. Auto Park Brake is enabled and disabled by
customer selection through the customer programmable
features
Úpage 132.
Any single Auto Park Brake application can be bypassed by
pushing the EPB switch to the release position while the
transmission is placed in PARK.
SafeHold
SafeHold is a safety feature of the EPB system that will
engage the parking brake automatically if the vehicle is
left unsecured while the ignition is in ON/RUN position.
The parking brake will automatically engage if all of the
following conditions are met:
 The vehicle is at a standstill.
 There is no attempt to press the brake pedal or accel -
erator pedal.
 The driver seat belt is unbuckled.
 The driver door is open.

SafeHold can be temporarily bypassed by pressing the
brake pedal and pushing the EPB Switch while the driver
door is open. Once manually bypassed, SafeHold will be
enabled again once the vehicle reaches 12 mph (20 km/h)
or the ignition is turned to the OFF position and back to ON
again.

Brake Maintenance Mode
We recommend having your brakes serviced by an
authorized dealer. You should only make repairs for which
you have the knowledge and the right equipment. You
should only enter Brake Maintenance mode during brake
service. When servicing your rear brakes, it may be necessary for
you or your technician to push the rear piston into the rear
caliper bore. With the EPB system, this can only be done
after retracting the EPB actuator. Fortunately, actuator
retraction can be done easily by entering the Brake
Maintenance mode through the Uconnect Settings in your
vehicle. This menu-based system will guide you through
the steps necessary to retract the EPB actuator in order to
perform rear brake service.
Maintenance mode has requirements that must be met in
order to be activated:

The vehicle must be at a standstill.
 The parking brake must be unapplied.
 The transmission must be in PARK (P) or NEUTRAL (N).
While in Maintenance Mode, the EPB Warning Light will
flash continuously while the ignition is ON.
When brake service work is complete, the following steps
must be followed to reset the parking brake system to
normal operation:
 Ensure the vehicle is at a standstill.
 Press the brake pedal with moderate force.
 Apply the EPB Switch.
WARNING!
Driving the vehicle with the parking brake engaged, or
repeated use of the parking brake to slow the vehicle,
may cause serious damage to the brake system. Be
sure the parking brake is fully disengaged before
driving; failure to do so can lead to brake failure and a
collision.
WARNING!
You can be badly injured working on or around a motor
vehicle. Do only that service work for which you have
the knowledge and the right equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.

23_KL_OM_EN_USC_t.book Page 80

84STARTING AND OPERATING
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission
automatically upshifts through all forward gears.
When frequent transmission shifting occurs (such as
when operating the vehicle under heavy loading
conditions, in hilly terrain, traveling into strong head
winds, or while towing a heavy trailer), use the AutoStick
shift control to select a lower gear
Úpage 84. Under
these conditions, using a lower gear will improve
performance and extend transmission life by reducing
excessive shifting and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller may modify the
transmission shift schedule, reduce engine torque, and/or
expand the range of torque converter clutch engagement.
This is done to prevent transmission damage due to
overheating.
If the transmission becomes extremely hot, the
Transmission Temperature Warning Light may illuminate,
and the transmission may operate differently until the
transmission cools down.
During cold temperatures, transmission operation may be
modified depending on engine and transmission
temperature as well as vehicle speed. This feature
improves warm-up time of the engine and transmission to
achieve maximum efficiency. Engagement of the torque
converter clutch, and shifts into EIGHTH or NINTH gear,
are inhibited until the transmission fluid is warm
Úpage 85. Normal operation will resume once the
transmission temperature has risen to a suitable level.
SPORT — If Equipped
This mode alters the transmission's automatic shift
schedule for sportier driving. Upshift speeds are increased
to make full use of available engine power.
SPORT mode is activated using the rotary switch on the
center console
Úpage 88.
Transmission Limp Home Mode
Transmission function is monitored electronically for
abnormal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
mode is activated. In this mode, the transmission may
operate only in a fixed gear, or may remain in NEUTRAL.
The Malfunction Indicator Light (MIL) may be illuminated.
Limp Home mode may allow the vehicle to be driven to an
authorized dealer for service without damaging the
transmission.
In the event of a momentary problem, the transmission
can be reset to regain all forward gears by performing the
following steps:

1. Stop the vehicle.

2. Shift the transmission into PARK.
3. Turn the ignition to the OFF position.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Shift into the desired gear range. If the problem is no longer detected, the transmission will return to
normal operation.
NOTE:Even if the transmission can be reset, we recommend that
you visit an authorized dealer at your earliest possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission. If
the transmission cannot be reset, authorized dealer
service is required.
AutoStick
AutoStick is a driver interactive transmission feature
providing manual shift control, giving you more control of
the vehicle. AutoStick allows you to maximize engine
braking, eliminate undesirable upshifts and downshifts,
and improve overall vehicle performance. This feature can
also provide you with more control during passing, city
driving, cold slippery conditions, mountain driving, trailer
towing and many other situations.
Operation
When the gear selector is in the AutoStick position (beside
the DRIVE position), it can be moved forward and
rearward. This allows the driver to manually select the
transmission gear being used. Moving the gear selector
forward (-) triggers a downshift, and rearward (+) an
upshift. The current gear is displayed in the instrument
cluster.
NOTE:
In AutoStick mode, the transmission will only shift up or
down when the driver moves the gear selector rearward (+)
or forward (-), except as follows:


The transmission will automatically upshift when
necessary to prevent engine overspeed.
 The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.

88STARTING AND OPERATING
SELEC-TERRAIN
DESCRIPTION
Selec-Terrain allows the driver to specify the driving
surface to allow the vehicle systems to provide the best
performance possible across a wide range of conditions.
Rotate the Selec-Terrain knob to select the desired mode.

Selec-Terrain Switch

Selec-Terrain offers the following modes:
AUTO — Fully automatic, full-time four-wheel drive oper -
ation can be used on and off-road. Balances traction
with a seamless steering feel to provide improved
handling and acceleration.
 SNOW — Tuning set for additional stability in inclement
weather. Use when driving on loose traction surfaces
such as snow, while either on or off-road. When in
SNOW mode (depending on certain operating condi -tions), the transmission may use SECOND gear (rather
than FIRST gear) during launches, to minimize wheel
slippage.
 SPORT — This mode alters the transmission's auto -
matic shift schedule for sportier driving. Upshift speeds
are increased to make full use of available engine
power.
NOTE:SPORT mode is not available when 4WD LOW is selected.
 SAND/MUD — Off-road calibration for use on low trac -
tion surfaces such as mud, sand, or wet grass. The
4WD system provides maximum capability to all
wheels. Some binding may be felt on high traction
surfaces. The electronic brake system will be adjusted
to reduce the automatic braking of slipping wheels and
to allow the engine to operate without restriction.
 ROCK — Off-road calibration is only available in 4WD
LOW range. ROCK mode provides the most aggressive
four-wheel drive performance for extreme off-road
terrain. Use for low speed obstacles such as large
rocks, deep ruts, etc. The driver may notice additional
tire scrubbing and steering wheel feedback while
driving in ROCK mode on higher traction off-road
surfaces. For use only in off-road driving situations.
NOTE:
 ROCK mode is only available on the vehicles equipped
with the Off-Road package.
 Activate the Hill Descent Control or Selec-Speed
Control for steep downhill control
Úpage 143.
Instrument Cluster Display Messages
When the appropriate conditions exist, a message will
appear in the instrument cluster Úpage 63.
POWER STEERING
The power steering system will provide increased vehicle
response and ease of maneuverability. The power steering
system adapts to different driving conditions.
If the “SERVICE POWER STEERING” or “POWER
STEERING ASSIST OFF - SERVICE SYSTEM”
message and a steering wheel icon are
displayed on the instrument cluster display
screen, it indicates that the vehicle needs to be taken to
an authorized dealer for service. It is likely the vehicle has
lost power steering assistance
Úpage 68.
If the “POWER STEERING SYSTEM HOT - PERFORMANCE
MAY BE LIMITED” message and an icon are displayed on
the instrument cluster display screen, it indicates that
extreme steering maneuvers may have occurred, which
caused an over temperature condition in the power
steering system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, pull over
and let the vehicle idle for a few moments until the light
turns off
Úpage 68.
WARNING!
Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.

23_KL_OM_EN_USC_t.book Page 88

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

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.

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

23_KL_OM_EN_USC_t.book Page 103

STARTING AND OPERATING125
NOTE:Remember, never drive diagonally across a hill — drive
straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels slowly left and right. This may
provide a fresh “bite” into the surface and may provide
traction to complete the climb.
Traction Downhill
Shift the transmission into a low gear and the 4WD system
to 4WD LOW range or Select Hill Descent Control (if
equipped)
Úpage 143. Let the vehicle go slowly down the
hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmission
whenever possible.
After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is always
a good idea to check for damage.
 Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
 Inspect the radiator for mud and debris and clean as
required.
 Check threaded fasteners for looseness, particularly
on the chassis, drivetrain components, steering, and
suspension. Retighten them, if required, and torque to
the values specified in the Service Manual.
 Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts. 
After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.
 Impacted material can cause wheel imbalance.
Freeing the wheels of impacted material will likely
rectify imbalance condition.
WARNING!
Abrasive material in any part of the braking system may
cause excessive wear or unpredictable braking
performance. Full braking power may not be available
to prevent a collision. If you have been operating your
vehicle in dirty conditions, inspect and clean the
braking components as soon as possible.
