Exhaust GasThe best protection against carbon monoxide
entry into the vehicle body is a properly
maintained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the
complete exhaust system and adjacent body
areas for broken, damaged, deteriorated, or
mispositioned parts. Open seams or loose
connections could permit exhaust fumes to
seep into the passenger compartment. In
addition, inspect the exhaust system each
time the vehicle is raised for lubrication or oil
change. Replace as required.
Safety Checks You Should Make Inside
The Vehicle
Seat Belts

Inspect the seat belt system periodically,
checking for cuts, frays, and loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies
must be replaced after a collision if they
have been damaged (i.e., bent retractor, torn
webbing, etc.). If there is any question
regarding seat belt or retractor condition,
replace the seat belt.
Air Bag Warning Light
The Air Bag warning light will turn on for
four to eight seconds as a bulb check when
the ignition switch is first turned to ON/RUN.
If the light is either not on during starting,
stays on, or turns on while driving, have the
system inspected at an authorized dealer as
soon as possible. After the bulb check, this
light will illuminate with a single chime when
a fault with the Air Bag System has been
detected. It will stay on until the fault is
removed. If the light comes on intermittently
or remains on while driving, have an autho
-
rized dealer service the vehicle immediately.
Refer to “Occupant Restraint Systems” in
“Safety” for further information.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage
or in confined areas any longer than
needed to move your vehicle in or out of
the area.
If you are required to drive with the
trunk/liftgate/rear doors open, make sure
that all windows are closed and the
climate control BLOWER switch is set at
high speed. DO NOT use the recircula-
tion mode.
If it is necessary to sit in a parked vehicle
with the engine running, adjust your
heating or cooling controls to force
outside air into the vehicle. Set the
blower at high speed.

Defroster
Check operation by selecting the defrost
mode and place the blower control on high
speed. You should be able to feel the air
directed against the windshield. See an
authorized dealer for service if your defroster
is inoperable.
Floor Mat Safety Information
Always use floor mats designed to fit your
vehicle. Only use a floor mat that does not
interfere with the operation of the acceler -
ator, brake or clutch pedals. Only use a floor
mat that is securely attached using the floor
mat fasteners so it cannot slip out of position
and interfere with the accelerator, brake or
clutch pedals or impair safe operation of your
vehicle in other ways.
WARNING!
An improperly attached, damaged, folded,
or stacked floor mat, or damaged floor mat
fasteners may cause your floor mat to
interfere with the accelerator, brake, or
clutch pedals and cause a loss of vehicle
control. To prevent SERIOUS INJURY or
DEATH:
ALWAYS securely attach your floor
mat using the floor mat fasteners. DO
NOT install your floor mat upside down
or turn your floor mat over. Lightly pull to
confirm mat is secured using the floor
mat fasteners on a regular basis.
ALWAYS REMOVE THE EXISTING
FLOOR MAT FROM THE VEHICLE
before installing any other floor mat.
NEVER install or stack an additional
floor mat on top of an existing floor mat.
ONLY install floor mats designed to fit
your vehicle. NEVER install a floor mat
that cannot be properly attached and
secured to your vehicle. If a floor mat
needs to be replaced, only use a FCA
approved floor mat for the specific make,
model, and year of your vehicle.
WARNING! (Continued)
ONLY use the driver’s side floor mat on
the driver’s side floor area. To check for
interference, with the vehicle properly
parked with the engine off, fully depress
the accelerator, the brake, and the
clutch pedal (if present) to check for
interference. If your floor mat interferes
with the operation of any pedal, or is not
secure to the floor, remove the floor mat
from the vehicle and place the floor mat
in your trunk.
ONLY use the passenger’s side floor mat
on the passenger’s side floor area.
ALWAYS make sure objects cannot fall
or slide into the driver’s side floor area
when the vehicle is moving. Objects can
become trapped under accelerator,
brake, or clutch pedals and could cause
a loss of vehicle control.
NEVER place any objects under the floor
mat (e.g., towels, keys, etc.). These
objects could change the position of the
floor mat and may cause interference
with the accelerator, brake, or clutch
pedals.

STARTING AND OPERATING
STARTING THE ENGINE
Before starting your vehicle, adjust your seat,
adjust both inside and outside mirrors, and
fasten your seat belts.Start the engine with the gear selector in the
NEUTRAL or PARK position. Apply the brake
before shifting to any driving range.
Normal Starting — Gasoline Engine
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pushing the accelerator pedal.
Place your foot on the brake and place the
ignition to the START mode and release
when the engine starts. If the engine fails to
start within 10 seconds:
1. Place the ignition in the OFF mode.
2. Wait 10 to 15 seconds.
3. Repeat the “Normal Starting” procedure.NOTE:
Only press one pedal at a time while driving
the vehicle. Torque performance of the
vehicle could be reduced if both pedals are
pressed at the same time. If pressure is
detected on both pedals simultaneously, a
warning message will display in the instru
-
ment cluster. For further information, refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel”.
Tip Start Feature
Place the ignition in the START mode and
release it as the starter engages. The starter
motor will automatically disengage itself
once the engine is running. If the engine fails
to start, the starter will disengage automati -
cally in 10 seconds. If this occurs:
1. Place the ignition in the OFF mode.
2. Wait 10 to 15 seconds.
3. Repeat the “Normal Starting” procedure.
WARNING!
When leaving the vehicle, always remove
the key fob from the ignition and lock
your vehicle. If equipped with Keyless
Enter-N-Go, always make sure the
keyless ignition node is in “OFF” mode,
remove the key fob from the vehicle and
lock the vehicle.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Allowing children to be in a vehicle unat -
tended 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 the ignition of

Normal Starting — Diesel Engine
Before starting your vehicle, adjust your seat,
both inside and outside mirrors, and fasten
your seat belts.
The starter is allowed to crank for up to
30-second intervals. Waiting a few minutes
between such intervals will protect the
starter from overheating.NOTE:
Engine start up in very low ambient tempera-
ture could result in evident white smoke.
This condition will disappear as the engine
warms up.
Battery Blanket Usage
A battery loses 60% of its cranking power as
the battery temperature decreases to 0°F
(-18°C). For the same decrease in tempera -
ture, the engine requires twice as much
power to crank at the same RPM. The use of
battery blankets will greatly increase starting
capability at low temperatures. Suitable
battery blankets are available from your
authorized Mopar dealer.
Normal Starting Procedure — Keyless
Enter-N-Go
Observe the instrument panel telltales when
starting the engine.
NOTE:
Normal starting of either a cold or a warm
engine is obtained without pumping or
pressing the accelerator pedal.
1. Always apply the parking brake.
2. Press and hold the brake pedal while pushing the ENGINE START/STOP
button once.
NOTE:
A delay of the start of up to five seconds is
possible under very cold conditions. The
“Wait to Start” telltale will be illuminated
WARNING!
Before exiting a vehicle, always come to
a complete stop, then shift the auto-
matic transmission into PARK and apply
the parking brake.
Always make sure the keyless ignition
node is in the OFF mode, key fob is
removed from the vehicle and vehicle is
locked.
Never leave children alone in a vehicle,
or with access to an unlocked vehicle.
Leaving children in a vehicle unattended
is dangerous for a number of reasons. A
child or others could be seriously 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 the ignition of
a vehicle equipped with Keyless
Enter-N-Go in the ACC or ON/RUN
mode. A child could operate power
windows, other controls, or move the
vehicle.
Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
CAUTION!
The engine is allowed to crank as long as
30 seconds. If the engine fails to start
during this period, please wait at least two
minutes for the starter to cool before
repeating start procedure.

during the pre-heat process, When the
engine “Wait To Start” telltale goes off the
engine will automatically crank.
3. The system will automatically engage thestarter to crank the engine. If the vehicle
fails to start, the starter will disengage
automatically after 30 seconds.
4. If you wish to stop the cranking of the engine prior to the engine starting, push
the ENGINE START/STOP button again.
5. Check that the oil pressure warning light has turned off.
6. Release the parking brake.Engine Warm Up
Avoid full throttle operation when the engine
is cold. When starting a cold engine, bring
the engine up to operating speed slowly to
allow the oil pressure to stabilize as the
engine warms up.
NOTE:
High-speed, no-load running of a cold engine
can result in excessive white smoke and poor
engine performance. No-load engine speeds
should be kept under 1,200 RPM during the
warm-up period, especially in cold ambient
temperature conditions.
ENGINE BREAK-IN
RECOMMENDATIONS
A long break-in period is not required for the
engine and drivetrain (transmission and axle)
in your vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles
(100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable. While cruising, brief full-throttle accelera
-
tion within the limits of local traffic laws
contributes to a good break-in. Wide-open
throttle acceleration in low gear can be detri -
mental and should be avoided.
The engine oil installed in the engine at the
factory is a high-quality energy conserving
type lubricant. Oil changes should be consis -
tent with anticipated climate conditions
under which vehicle operations will occur.
For the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical Specifications”.
NOTE:
A new engine may consume some oil during
its first few thousand miles (kilometers) of
operation. This should be considered a
normal part of the break-in and not inter -
preted as a problem.
CAUTION!
To prevent damage to the starter, do not
crank continuously for more than 10
seconds at a time. Wait 10 to 15 seconds
before trying again.
CAUTION!
Never use Non-Detergent Oil or Straight
Mineral Oil in the engine or damage may
result.

PARKING BRAKE
Electric Park Brake (EPB)
Your vehicle is equipped with a new Electric
Park Brake System (EPB) that offers greater
convenience. The park brake switch is
located in the center console.Park Brake Switch
To apply the park brake manually, pull up on
the switch momentarily. The BRAKE telltale
light in the instrument cluster and an indi -
cator on the switch will illuminate. To release the park brake manually, the igni
-
tion must be in ON/RUN. Then put your foot
on the brake pedal and push the park brake
switch down momentarily. Once the park
brake is fully disengaged, the BRAKE telltale
light and the switch indicator will extinguish.
The park brake can also be automatically
released. With the engine running and the
transmission in gear, release the brake pedal
and depress the throttle pedal. For safety
reasons, your seat belt must also be
fastened.
NOTE:
You may hear a slight whirring sound from
the back of the vehicle while the parking
brake engages or disengages.
If your foot is on the brake pedal while you
are engaging or disengaging the parking
brake, you may notice a small amount of
brake pedal movement.
The Auto Park Brake feature can be used
to apply the park brake automatically
every time you park the vehicle. Auto Park
Brake can be enabled and disabled in the
Settings menu in Uconnect.
The parking brake can be engaged even
when the ignition is OFF, however, it can
only be disengaged when the ignition is in
the ON/RUN mode.
SafeHold is a feature that will automati -
cally apply the park brake under certain
conditions. The EPB monitors the status
of the driver’s seat belt, driver’s door and
pedal positions to determine if the driver
may have exited while the vehicle is still
capable of moving and will then automati -
cally apply the park brake to prevent the
vehicle from rolling.
The EPB fault 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.

147
NOTE:
You must press and hold the brake pedal
while shifting out of PARK.
Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition
Park Interlock which requires the transmis-
sion to be in PARK before the ignition can be
turned to the LOCK/OFF (key removal) posi -
tion. The key fob can only be removed from
the ignition when the ignition is in the LOCK/
OFF position, and the transmission is locked
in PARK whenever the ignition is in the
LOCK/OFF position.
Brake/Transmission Shift Interlock
System
This vehicle is equipped with a Brake Trans -
mission Shift Interlock system (BTSI) that
holds the transmission gear selector in PARK
unless the brakes are applied. To shift the
transmission out of PARK, the ignition must
be in the ON/RUN mode (engine running or
not) and the brake pedal must be pressed.
The brake pedal must also be pressed to shift
from NEUTRAL into DRIVE or REVERSE
when the vehicle is stopped or moving at low
speeds.
Nine-Speed Automatic Transmission
The transmission gear range (PRND) is
displayed both beside the gear selector and
in the instrument cluster. To select a gear
range, press the lock button on the gear
selector and move the selector rearward or
forward. You must also press the brake pedal
to shift the transmission out of PARK (or
NEUTRAL, when the vehicle is stopped or
moving at low speeds). Select the DRIVE
range for normal driving. NOTE:
In the event of a mismatch between the gear
selector position and the actual transmission
gear (for example, driver selects REVERSE
while driving forward), the position indicator
will blink continuously until the selector is
returned to the proper position, or the
requested shift can be completed.
The electronically-controlled transmission
adapts its shift schedule based on driver
inputs, along with environmental and road
conditions. The transmission electronics are
self-calibrating; therefore, the first few shifts
on a new vehicle may be somewhat abrupt.
This is a normal condition, and precision
shifts will develop within a few hundred
miles (kilometers).
The nine-speed transmission has been devel
-
oped to meet the needs of current and future
FWD/AWD vehicles. Software and calibration
is refined to optimize the customer’s driving
experience and fuel economy. By design,
some vehicle and driveline combinations
utilize 9th gear only in very specific driving
situations and conditions.
CAUTION!
Shift into or out of PARK or REVERSE
only after the vehicle has come to a
complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is
above idle speed.
Before shifting into any gear, make sure
your foot is firmly pressing the brake
pedal.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 147

149
NOTE:
In AutoStick mode, the transmission will
only shift up or down when the driver moves
the gear selector rearward (+) or forward (-),
except as described below.
The transmission will automatically
upshift when necessary to prevent engine
overspeed.
The transmission will automatically down-
shift as the vehicle slows (to prevent
engine lugging) and will display the
current gear.
The transmission will automatically down -
shift to FIRST or SECOND gear
(depending on model) when coming to a
stop. After a stop, the driver should manu -
ally upshift (+) the transmission as the
vehicle is accelerated.
You can start out (from a stop) in FIRST or
SECOND gear. Starting out in SECOND
gear can be helpful in snow or icy condi -
tions. Tap the gear selector forward or
rearward to select the desired gear after
the vehicle is brought to a stop.
If a requested downshift would cause the
engine to overspeed, that shift will not
occur.
The system will ignore attempts to upshift
at too low of a vehicle speed.
Avoid using Speed Control when AutoStick
is engaged because the transmission will
not shift automatically.
Transmission shifting will be more notice-
able when AutoStick is enabled.
The system may revert to automatic shift
mode if a fault or overheat condition is
detected. To disengage AutoStick mode, return the
gear selector to the DRIVE position. You can
shift in or out of the AutoStick position at any
time without taking your foot off the acceler
-
ator pedal.
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip and the
vehicle could skid, causing a collision or
personal injury.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 149

153
NOTE:
It may also be necessary to drive slowly
steering back and forth to complete
engagement and disengagement of the
E-Locker.

When disengaging Rear E-Locker, the indi-
cator lights in the instrument cluster and on
the REAR LOCK button will begin to flash.
When the shift is complete the REAR LOCK
indicator lights will remain off.

Shifting into or out of Rear E-Locker is
possible with the vehicle completely
stopped; however, difficulty may occur
due to the mating clutch teeth not being
properly aligned. Several attempts may be
required for clutch teeth alignment and
shift completion to occur. The preferred
method is for the vehicle to be rolling,
below 15 mph (24 km/h), while including
right and left steering maneuvers to allow
for the clutch teeth to align.
The Rear E-Locker System must be disen -
gaged prior to taking the vehicle out of
4WD LOW range. If 4WD LOW shift condi -
tions/interlocks are not met, a message
will flash from the instrument cluster
display with instructions on how to
complete the requested shift.
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 operation can be used
both on and off road. Balances traction
with 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
conditions), the transmission may use
SECOND gear (rather than FIRST gear)
during launches, to minimize wheel slip -
page.
SPORT — This mode alters the transmis -
sion's automatic 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 traction 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.

(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 tempera-
ture 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.

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).
PARKSENSE REAR PARK
ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system
provides visual and audible indications of
the distance between the rear fascia and a
detected obstacle when backing up (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. Refer to “Ucon
-
nect Settings” in “Multimedia” in the
Owner’s Manual for information on turning
Rear Braking Assist on or off.
Refer to “ParkSense System Usage Precau -
tions” in this section for limitations of this
system and recommendations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the ON/
RUN position.
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 orienta -
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be
displayed if Sound and Display is selected
from the Customer - Programmable Features
section of the Uconnect System.
Refer to "Uconnect Settings” in “Multi -
media” in the Owner’s Manual for further
information.
The ParkSense Warning screen is located
within the instrument cluster display. It
provides visual warnings to indicate the
distance between the rear fascia/bumper and
the detected obstacle.
