2023 JEEP CHEROKEE service indicator

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.

23_KL_OM_EN_USC_t.book Page 84

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

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, or extremely hot or cold
ambient temperatures will influence when the “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under Instrument Cluster
Display
Úpage 64.
NOTE:Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), 12 months or
350 hours of engine run time, whichever comes first. The
350 hours of engine run or idle time is generally only a
concern for fleet customers.
At Every Fuel Stop:

Check engine oil level.
 Check windshield washer fluid level.
 Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before the oil indicator system turns
on.
 Check the fluid levels of the coolant reservoir and
brake master cylinder; fill as needed.
 Check function of all interior and exterior lights.

SERVICING AND MAINTENANCE219
5. Remove the cabin air filter by pulling it straight out of
the housing. Take note of the air filter position
indicators.

Cabin Air Filter

6. Install the cabin air filter with the air filter position indicators pointing in the same direction as removal.
7. Install the passenger side hush panel under the dash panel and console closeout cover.
Refer to the Maintenance Plan in this chapter for the
proper maintenance intervals
Úpage 209.
BODY LUBRICATION
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should be
lubricated periodically with a lithium based grease, such
as Mopar® Spray White Lube to ensure quiet, easy
operation and to protect against rust and wear. Prior to the
application of any lubricant, the parts concerned should
be wiped clean to remove dust and grit; after lubricating,
excess oil and grease should be removed. Particular
attention should also be given to hood latching
components to ensure proper function. When performing
other underhood services, the hood latch, release
mechanism and safety catch should be cleaned and
lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Autumn and Spring. Apply a small
amount of a high quality lubricant, such as Mopar® Lock
Cylinder Lubricant directly into the lock cylinder.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumulations
of salt or road film.
Operation of the wipers on dry glass for long periods may
cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield. Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending on
geographical area and frequency of use. If chattering,
marks, water lines or wet spots are present, clean the
wiper blades or replace as necessary.
The wiper blades and wiper arms should be inspected
periodically, not just when wiper performance problems
are experienced. This inspection should include the
following points:

Wear or uneven edges
 Foreign material
 Hardening or cracking
 Deformation or fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not
attempt to repair a wiper arm or blade that is damaged.
CAUTION!
The cabin air filter is identified with an arrow to indicate
airflow direction through the filter. Failure to properly
install the filter will result in the need to replace it more
often.

SERVICING AND MAINTENANCE243
(Continued)
Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be
replaced.

Tire Tread

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be
replaced
Úpage 243.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
Driving style.

 Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.

 Distance driven.
 Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle sched-
uled maintenance is highly recommended.
NOTE:Wheel Valve Stem must be replaced as well when
installing new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The
manufacturer strongly recommends that you use tires
equivalent to the originals in size, quality and performance
when replacement is needed
Úpage 243. Refer to the
Tire And Loading Information Placard or the Vehicle Certification Label for the size designation of your tire. The
Load Index and Speed Symbol for your tire will be found on
the original equipment tire sidewall.
See the Tire Sizing Chart example found in the Tire Safety
Information for more information relating to the Load
Index and Speed Symbol of a tire
Úpage 236.
It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the
original wheels.
It is recommended you contact an authorized tire dealer or
original equipment dealer with any questions you may
have on tire specifications or capability. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
1 — Tread Wear Indicators
WARNING!
Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to
follow this warning can result in sudden tire failure. You
could lose control and have a collision resulting in
serious injury or death.
WARNING!
 Do not use a tire, wheel size, load rating, or speed
rating other than that specified for your vehicle.
Some combinations of unapproved tires and wheels
may change suspension dimensions and perfor -
mance characteristics, resulting in changes to
steering, handling, and braking of your vehicle. This
can cause unpredictable handling and stress to
steering and suspension components. You could
lose control and have a collision resulting in serious
injury or death. Use only the tire and wheel sizes with
load ratings approved for your vehicle.

254TECHNICAL SPECIFICATIONS
Tighten the lug nuts/bolts in a star pattern until each nut/
bolt has been tightened twice. Ensure that the socket is
fully engaged on the lug nut/bolt (do not insert it halfway).

Torque Patterns

After 25 miles (40 km), check the lug nut/bolt torque to be
sure that all the lug nuts/bolts are properly tightened.
FUEL REQUIREMENTS
While operating on gasoline with the required octane
number, hearing a light knocking sound from the engine is
not a cause for concern. However, if the engine is heard
making a heavy knocking sound, see a dealer
immediately. Use of gasoline with a lower than recommended octane number can cause engine failure
and may void or not be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such as hard
starting, stalling, and hesitations. If you experience these
symptoms, try another brand of gasoline before
considering service for the vehicle.
2.0L ENGINE
This engine is designed to meet all emission
requirements, and provide satisfactory fuel
economy and performance, when using
unleaded regular gasoline having an octane
rating of 87, as specified by the (R+M)/2 method. The use
of 91 or higher octane premium gasoline will allow these
engines to operate to optimal performance. This increase
in performance is most noticeable in hot weather or under
heavy load conditions, such as while towing.
2.4L ENGINE
This engine is designed to meet all emission
regulations and provide optimum fuel economy
and performance when using unleaded regular
gasoline having a posted octane number of 87
as specified by the (R+M)/2 method. The use of higher
octane premium gasoline is not required, as it will not
provide any benefit over regular gasoline in these engines.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner-burning gasoline referred to as “reformulated
gasoline”. Reformulated gasoline contains oxygenates
and are specifically blended to reduce vehicle emissions
and improve air quality.
The use of reformulated gasoline is recommended.
Properly blended reformulated gasoline will provide
improved performance and durability of engine and fuel
system components.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with
oxygenates such as ethanol.
Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void the New Vehicle Limited Warranty.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug nuts/bolts fully until the vehicle has
been lowered. Failure to follow this warning may result
in personal injury.
CAUTION!
DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the Malfunction Indicator Light to
illuminate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than
15% ethanol (E-15).

23_KL_OM_EN_USC_t.book Page 254

TECHNICAL SPECIFICATIONS255
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Use of gasoline with
higher ethanol content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,
the engine will have some or all of these symptoms:
 Operate in a lean mode.
 OBD II Malfunction Indicator Light on.
 Poor engine performance.
 Poor cold start and cold drivability.
 Increased risk for fuel system component corrosion.
CNG AND LP FUEL SYSTEM
M
ODIFICATIONS
Modifications that allow the engine to run on Compressed
Natural Gas (CNG) or Liquid Propane (LP) may result in
damage to the engine, emissions, and fuel system
components. Problems that result from running CNG or LP
are not the responsibility of the manufacturer and may
void the New Vehicle Limited Warranty.
METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive that is
blended into some gasolines to increase octane. Gasoline
blended with MMT provides no performance advantage beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug life
and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline pump;
therefore, you should ask the gasoline retailer whether the
gasoline contains MMT. MMT is prohibited in Federal and
California reformulated gasoline.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.
Designated TOP TIER Detergent Gasoline
contains a higher level of detergents to further
aide in minimizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent Gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER Detergent
Gasoline retailers.
Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and
diaphragm materials.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control system
can result in civil penalties being assessed against you.
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
 The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor -
mance and damage the emissions control system.
 An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact an authorized dealer for service assistance.
 The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of meth -
anol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or addi -
tives is not the responsibility of the manufacturer
and may void or not be covered under the New
Vehicle Limited Warranty.
