front of the engine compartment, behind the
left headlight assembly.Positive Battery Post NOTE:
Never use a fast battery charger to start the
engine, as this could damage the electronic
systems of your vehicle, particularly the igni
-
tion and engine fuel supply control units.
1. Apply the parking brake, shift the auto -
matic transmission into PARK (manual
transmission in NEUTRAL) and turn the
ignition OFF.
2. Turn off the heater, radio, and all unnec -
essary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the
jumper cables reach, apply the parking
brake and make sure the ignition is OFF.
Jump Starting Procedure
WARNING!
Take care to avoid the radiator cooling
fan whenever the hood is raised. It can
start anytime the ignition switch is ON.
You can be injured by moving fan blades.
Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
Batteries contain sulfuric acid that can
burn your skin or eyes and generate
hydrogen gas which is flammable and
explosive. Keep open flames or sparks
away from the battery.
WARNING! (Continued) WARNING!

Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.

WARNING!
Failure to follow this jump starting
procedure could result in personal injury or
property damage due to battery explosion.
CAUTION!
Failure to follow these procedures could
result in damage to the charging system of

Connecting The Jumper Cables
1. Connect the positive (+) end of the
jumper cable to the positive (+) post of
the discharged vehicle.

2. Connect the opposite end of the positive (+)
jumper cable to the positive (+) post of the
booster battery.

3. Connect the negative (-) end of the
jumper cable to the negative (-) post of
the booster battery.
4. Connect the opposite end of the negative (-) jumper cable to a good engine ground
(exposed metal part of the discharged
vehicle’s engine) away from the battery
and the fuel injection system. 5. Start the engine in the vehicle that has
the booster battery, let the engine idle for
a few minutes, and then start the engine
in the vehicle with the discharged
battery.
6. Once the engine is started, remove the jumper cables in the reverse sequence.
Disconnecting The Jumper Cables
1. Disconnect the negative (-) end of the
jumper cable from the engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the nega -
tive (-) jumper cable from the negative (-)
post of the booster battery.
3. Disconnect the positive (+) end of the
jumper cable from the positive (+) post of
the booster battery. 4. Disconnect the opposite end of the posi
-
tive (+) jumper cable from the positive
(+) post of the vehicle with the
discharged battery.
If frequent jump starting is required to start
your vehicle, you should have the battery and
charging system inspected at an authorized
dealer.
WARNING!
Do not connect the jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause
the battery to explode and could result in
personal injury. Only use the specific
ground point, do not use any other
exposed metal parts.
CAUTION!
Accessories plugged into the vehicle power
outlets draw power from the vehicle’s
battery, even when not in use (i.e., cellular
devices, etc.). Eventually, if plugged in
long enough without engine operation, the
vehicle’s battery will discharge sufficiently
to degrade battery life and/or prevent the
engine from starting.

REFUELING IN EMERGENCY —
IF EQUIPPED

The fuel filling procedure in case of emer-
gency is described in the “Emergency Gas
Can Refueling”. Refer to “Refueling The
Vehicle” in “Starting And Operating” for
further information.
The vehicle is equipped with a refueling
funnel. If refueling is necessary, while using
an approved gas can, please insert the refu -
eling funnel into the filler neck opening.
Refueling Funnel Inserting Funnel
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating your
engine by taking the appropriate action.
On the highways — slow down.
In city traffic — while stopped, place the
transmission in NEUTRAL, but do not
increase engine idle speed.
NOTE:
There are steps that you can take to slow
down an impending overheat condition:
If your Air Conditioner (A/C) is on, turn it
off. The A/C system adds heat to the
engine cooling system and turning the A/C
off can help remove this heat.
CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads “H,” pull over and stop the
vehicle. Idle the vehicle with the air
conditioner turned off until the pointer
drops back into the normal range. If the
pointer remains on the “H” and you hear
continuous chimes, turn the engine off
immediately and call for service.
2020_JEEP_CHEROKEE_UG_RHD_UK.book Page 212

213
You can also turn the temperature control
to maximum heat, the mode control to
floor and the blower control to high. This
allows the heater core to act as a supple-
ment to the radiator and aids in removing
heat from the engine cooling system.GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector
cannot be moved out of the PARK position,
you can use the following procedure to
temporarily move the gear selector:
1. Turn the engine OFF.
2. Apply the parking brake.
3. Using a screwdriver or similar tool, care-
fully separate the shifter bezel and boot
assembly from the center console, and
raise it up to access the gear selector
mechanism.
4. Press and maintain firm pressure on the brake pedal. 5. Insert a small screwdriver or similar tool
down into the gear selector override
access hole (at the left front corner of the
gear selector assembly), and push and
hold the override release lever down.
Override Access Hole
6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector boot.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand
or snow, it can often be moved using a
rocking motion. Turn the steering wheel right
and left to clear the area around the front
wheels. For vehicles with automatic trans-
mission, push and hold the lock button on
the gear selector. Then shift back and forth
between DRIVE and REVERSE (with auto -
matic transmission) or SECOND GEAR and
REVERSE (with manual transmission), while
gently pressing the accelerator.
NOTE:
For vehicles with automatic transmission:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two
seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking
motion without spinning the wheels or racing
the engine. NOTE:
Push the “ESC OFF” switch (if necessary), to
place the Electronic Stability Control (ESC)
system in “Partial Off” mode, before rocking
the vehicle. Refer to “Electronic Brake
Control System” in “Safety” for further infor
-
mation. Once the vehicle has been freed,
push the "ESC OFF" switch again to restore
“ESC On” mode.
CAUTION!
Racing the engine or spinning the wheels
may lead to transmission overheating
and failure. Allow the engine to idle with
the transmission in NEUTRAL for at
least one minute after every five
rocking-motion cycles. This will mini -
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
When “rocking” a stuck vehicle by
shifting between DRIVE/SECOND GEAR
and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drive -
train damage may result.
Revving the engine or spinning the
wheels too fast may lead to transmission
overheating and failure. It can also
damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,
of the axle and tires. A tire could explode
and injure someone. Do not spin your
vehicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
are stuck and do not let anyone near a
spinning wheel, no matter what the speed.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service.
Proper towing or lifting equipment is
required to prevent damage to your vehicle.
Use only tow bars and other equipment
designed for this purpose, following equip-
ment manufacturer’s instructions. Use of
safety chains is mandatory. Attach a tow bar
or other towing devices to main structural
members of the vehicle, not to bumpers or
associated brackets. State and local laws
regarding vehicles under tow must be
observed.
NOTE:
You must ensure that the Auto Park Brake
feature is disabled before towing this
vehicle, to avoid inadvertent Electric Park
Brake engagement. The Auto Park Brake feature is enabled or disabled via the
customer programmable features in the
Uconnect Settings.
Vehicles with a discharged battery or total
electrical failure when the electric park
brake (EPB) is engaged, will need a wheel
dolly or jack to raise the rear wheels off the
ground when moving the vehicle onto a
flatbed.
If you must use the accessories (wipers,
defrosters, etc.) while being towed, the igni -
tion must be in the ON/RUN mode, not the
ACC mode. NOTE:
The Safehold feature will engage the Electric
Park Brake whenever the driver's door is
opened (if the battery is connected, ignition
is ON, transmission is not in PARK, and
brake pedal is released). If you are towing
this vehicle with the ignition in the ON/RUN
mode, you must manually disable the Elec
-
tric Park Brake each time the driver's door is
opened, by pressing the brake pedal and
then releasing the EPB.
If the vehicle’s battery is discharged, refer to
“Gear Selector Override” in this section for
instructions on shifting the automatic trans -
mission out of PARK so that the vehicle can
be moved.

Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to
prevent damage to the vehicle.
Front-Wheel Drive (FWD) Models
The manufacturer recommends towing your
vehicle with all four wheels OFF the ground
using a flatbed.
If flatbed equipment is not available, this
vehicle must be towed with the front wheels
OFF the ground (using a towing dolly, or
wheel lift equipment with the front wheels
raised).
Ensure that the Electric Park Brake is
released, and remains released, while being
towed. The Electric Park Brake does not
need to be released, if all four wheels are off
the ground.
4x4 Models
The manufacturer requires towing with all
four wheels OFF the ground.
Acceptable methods are to tow the vehicle
on a flatbed, or with one end of vehicle raised
and the opposite end on a towing dolly.
CAUTION!
Do not use sling-type equipment when
towing. Vehicle damage may occur.
When securing the vehicle to a flatbed
truck, do not attach to front or rear
suspension components. Damage to your
vehicle may result from improper towing.
Ensure that the Electric Park Brake is
released, and remains released, while
being towed.
CAUTION!
Towing this vehicle in violation of the
above requirements can cause severe
engine and/or transmission damage.
Damage from improper towing is not
covered under the New Vehicle Limited
Warranty.
CAUTION!
Front or rear wheel lifts must not be used
(if the remaining wheels are on the
ground). Internal damage to the trans-
mission or power transfer unit will occur
if a front or rear wheel lift is used when
towing.
Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or power transfer unit
damage. Damage from improper towing
is not covered under the New Vehicle
Limited Warranty.

SERVICING AND MAINTENAN
CESCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the car under the best condi-
tions. For this reason, Jeep has planned a
series of checks and services at fixed
distance intervals and, where provided, at
fixed time intervals, as described in the
Scheduled Servicing plan. To keep the car’s
efficiency in tip-top condition, in the
following Scheduled Service plan pages a
few additional checks are listed that should
be carried out more frequently with respect
to the normal coupon redemption schedule.
Scheduled Servicing is offered by all autho -
rized dealerships according to fixed time or
mileage intervals. If, during each operation,
in addition to the ones scheduled, the need
arises for further replacements or repairs,
these may be carried out with the owner's
explicit agreement only.
The technicians at your dealership know your
vehicle best, and have access to factory
trained information, genuine Mopar parts,
and specially designed electronic and
mechanical tools that can help prevent
future costly repairs. If your car is used
frequently for towing, the interval between
one scheduled servicing operation and the next should be reduced. More frequent main
-
tenance may be needed for vehicles in severe
operating conditions, such as dusty areas
and very short trip driving.
NOTE:
Scheduled Servicing interventions are set
out by the Manufacturer. Failure to have
them carried out may invalidate the
warranty. It is advised to inform an autho -
rized dealership of any small operating irreg -
ularities without waiting for the next service.
Scheduled Servicing — Gasoline Engine
The oil change indicator system will remind
you that it is time to take your vehicle in for
engine oil replacement.
An “Oil Change Required” message will be
displayed in the instrument cluster and a
single chime will sound, indicating that an
oil change is necessary.
The oil change indicator message will illumi -
nate approximately 7,000 miles
(11,200 km) after the most recent oil
change was performed. Have your vehicle
serviced as soon as possible, within
500 miles (800 km). NOTE:
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle’s oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time (refer to the “Heavy Duty
Use of Vehicle” section).
Under no circumstances should oil change
intervals exceed 7,500 miles
(12,000 km) or 12 months, whichever
comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change.
