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.

STARTING AND OPERATING
140
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.

(Continued)
Refer to the Starting And Operating section
in the Owner’s Manual.
Auto Park Brake
The electric park brake can be programmed
to be applied automatically whenever the
vehicle is at a standstill and the automatic
transmission is placed in PARK, or with a
manual transmission, whenever the ignition
is turned “OFF”. Auto Park Brake is enabled
and disabled by customer selection through
the Customer Programmable Features
section of the Uconnect Settings.
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.
WARNING!
Never use the PARK position as a substi-
tute for the parking brake. Always apply
the parking brake fully when exiting the
vehicle to guard against vehicle move-
ment and possible injury or damage.
When exiting the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, 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 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 transmission
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
in the ACC or ON/RUN mode. A child
could operate power windows, other
controls, or move the vehicle.
Be sure the parking brake is fully disen -
gaged 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.

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.

WARNING! (Continued) 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.

SafeHold
SafeHold is a safety feature of the Electric
Park Brake System that will engage the park
brake automatically if the vehicle is left
unsecured while the ignition is in ON/RUN.
For automatic transmissions, the park brake
will automatically engage if all of the
following conditions are met:
The vehicle is at a standstill.
There is no attempt to depress the brake
pedal or accelerator pedal.
The seat belt is unbuckled.
The driver door is open.
For manual transmissions, the park brake
will automatically engage if all of the
following conditions are met:
The vehicle is at a standstill.
There is no attempt to depress the brake
pedal or accelerator pedal.
The clutch pedal is not pressed.
The seat belt is unbuckled.
The driver door is open.
MANUAL TRANSMISSION —
IF EQUIPPED NOTE:
During cold weather, you may experience
increased effort in shifting until the trans -
mission fluid warms up. This is normal.
Shifting
Fully press the clutch pedal before shifting
gears. As you release the clutch pedal, lightly
press the accelerator pedal.
You should always use FIRST gear when
starting from a standing position.
WARNING!
You or others could be injured if you leave
the vehicle unattended without having the
parking brake fully applied. The parking
brake should always be applied when the
driver is not in the vehicle, especially on
an incline.
CAUTION!
Never drive with your foot resting on the
clutch pedal, or attempt to hold the
vehicle on a hill with the clutch pedal
partially engaged, as this will cause
abnormal wear on the clutch.
Do not drive with your hand resting on
the gear selector as the force exerted,
even if slight, could lead over time to
premature wear of the gearbox internal
components.

Recommended Vehicle Shift Speeds
To utilize your manual transmission efficiently for fuel economy and performance, it should be upshifted as listed in the recommended shift
speed chart. Shift at the vehicle speeds listed for acceleration. When heavily loaded or pulling a trailer, these recommended up-shift speeds
may not apply.
Downshifting
Moving from a high gear down to a lower gear
is recommended to preserve brakes when
driving down steep hills. In addition, down-
shifting at the right time provides better
acceleration when you desire to resume
speed. Downshift progressively. Do not skip
gears to avoid overspeeding the engine and
clutch.
Manual Transmission Shift Speeds in MPH (KM/H)
All Engines Gear Selection 2 to 33 to 44 to 55 to 6
Accel. 24 (39) 34 (55) 47 (76) 56 (90)
Cruise 19 (31) 27 (43) 37 (60) 41 (66)
WARNING!
Do not downshift for additional engine
braking on a slippery surface. The drive
wheels could lose their grip, and the
vehicle could skid.
CAUTION!
Skipping gears and downshifting into
lower gears at higher vehicle speeds can
damage the engine and clutch systems,
Any attempt to shift into lower gear with
clutch pedal depressed may result
damage to the clutch system. Shifting
into lower gear and releasing the clutch
may result in engine damage.
When descending a hill, be very careful
to downshift one gear at a time to
prevent overspeeding the engine which
can cause engine damage, and/or clutch
damage, even if the clutch pedal is
pressed. If transfer case is in low range
the vehicle speeds to cause engine and
clutch damage are significantly lower.
Failure to follow the maximum recom -
mended downshifting speeds may cause
the engine damage and/or damage the
clutch, even if the clutch pedal is
pressed.
Descending a hill in low range with
clutch pedal depressed could result in
clutch damage.
CAUTION! (Continued)

Maximum Recommended Downshift Speeds
CAUTION!
Failure to follow the maximum
recommended downshifting speeds may
cause the engine to overspeed and/or
damage the clutch disc, even if the clutch
pedal is pressed.
Manual Transmission Downshift Speeds in MPH (KM/H)
Gear Selection 6 to 55 to 44 to 33 to 22 to 1

CAUTION!
If you skip a gear while downshifting or
downshift at too high of a vehicle speed,
these conditions may cause the engine to
overspeed if too low of a gear is selected
and the clutch pedal is released. Damage
to the clutch and the transmission can
result from skipping a gear while
downshifting or downshifting at too high of
a vehicle speed even if the clutch pedal is
held pressed (i.e., not released).

AUTOMATIC
TRANSMISSION — IF
EQUIPPED
WARNING!
It is dangerous to shift out of PARK (P)
or NEUTRAL (N) if the engine speed is
higher than idle speed. If your foot is not
firmly pressing the brake pedal, the
vehicle could accelerate quickly forward
or in reverse. You could lose control of
the vehicle and hit someone or some-
thing. Only shift into gear when the
engine is idling normally and your foot is
firmly pressing the brake pedal.
Unintended movement of a vehicle could
injure those in or near the vehicle. As
with all vehicles, you should never exit a
vehicle while the engine is running.
Before exiting a vehicle, always come to
a complete stop, then apply the parking
brake, shift the transmission into PARK,
turn the engine OFF, and remove the key
fob. When the ignition is in the LOCK/
OFF (key removal) position, (or, with
Keyless Enter-N-Go, when the ignition is
in the OFF mode) the transmission is
locked in PARK, securing the vehicle
against unwanted movement.
When leaving the vehicle, always make
sure the ignition is in the OFF mode,
remove the key fob from the vehicle, and
lock the vehicle.
Never use the PARK position as a substi
-
tute for the parking brake. Always apply
the parking brake fully when exiting the
vehicle to guard against vehicle move-
ment and possible injury or damage.
WARNING! (Continued)
Your vehicle could move and injure you
and others if it is not in PARK. Check by
trying to move the gear selector out of
PARK with the brake pedal released.
Make sure the transmission is in PARK
before exiting 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 transmission
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
(in 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.
WARNING! (Continued)
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 146

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

STARTING AND OPERATING
148
Only shift from DRIVE to PARK or REVERSE
when the accelerator pedal is released and
the vehicle is stopped. Be sure to keep your
foot on the brake pedal when shifting
between these gears.
The transmission gear selector provides
PARK, REVERSE, NEUTRAL, DRIVE, and
MANUAL (AutoStick) shift positions. Manual
shifts can be made using the AutoStick shift
control. Moving the gear selector into the
MANUAL (-/+) position (beside the DRIVE
position) activates AutoStick mode,
providing manual shift control and displaying
the current gear in the instrument cluster (as
1, 2, 3, etc.). Toggling the gear selector
forward (-) or rearward (+) while in the
MANUAL position will manually select the
transmission gear.
Refer to “AutoStick” in the Owner’s Manual.
NOTE:
If the gear selector cannot be moved to the
PARK, REVERSE, or NEUTRAL position
(when pushed forward) it is probably in the
MANUAL (AutoStick, (+/-)) position (beside
the DRIVE position). In MANUAL (AutoStick)
mode, the transmission gear (1, 2, 3, etc.) isdisplayed in the instrument cluster. Move
the gear selector to the right (into the DRIVE
[D] position) for access to PARK, REVERSE,
and NEUTRAL.
Gear Selector
Gear Ranges
Do not depress the accelerator pedal when
shifting from PARK or NEUTRAL into
another gear range.
NOTE:
After selecting any gear range, wait a
moment to allow the selected gear to engage
before accelerating. This is especially
important when the engine is cold.
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, elim -
inate undesirable upshifts and downshifts,
and improve overall vehicle performance.
This system can also provide you with more
control during passing, city driving, cold slip -
pery 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 transmis -
sion gear being used. Moving the gear
selector forward (-) triggers a downshift, and
rearward (+) an upshift. The current gear is
displayed in the instrument cluster.
