Jeep Cherokee (2019 year). Manual — part 28

• 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 supplement
to the radiator and aids in removing heat from the
engine cooling system.

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.

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, carefully 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 right front
corner of the gear selector assembly), and push and hold
the override release lever down.

6. Move the gear selector to the NEUTRAL position.

7. The vehicle may then be started in NEUTRAL.

8. Reinstall the gear selector boot.

IN CASE OF EMERGENCY

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. Push and hold the lock button on the gear selector.
Then shift back and forth between DRIVE and REVERSE,
while gently pressing the accelerator.

NOTE:

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.

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.

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 information.
Once the vehicle has been freed, push the

⬙ESC Off⬙ switch

again to restore “ESC On” mode.

IN CASE OF EMERGENCY

437

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 minimize 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 and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain 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 transmis-
sion shifting occurring).

TOWING A DISABLED VEHICLE

This section describes procedures for towing a disabled
vehicle using a commercial towing service.

If the transmission and drivetrain are operable, disabled
4x4 vehicles may also be towed as described under “Rec-
reational Towing” in the “Starting And Operating” section.

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 equipment
manufacturer’s instructions. Use of safety chains is man-
datory. Attach a tow bar or other towing device to main
structural members of the vehicle, not to bumpers or
associated brackets. State and local laws regarding vehicles
under tow must be observed.

IN CASE OF EMERGENCY

439

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 program-
mable 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 ignition must be in the ON/RUN
mode, not the ACC mode.

Note that the Safehold feature will engage the Electric Park
Brake whenever the driver’s door is opened (if the 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 key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Gear Selector Override” in this section

for instructions on shifting the transmission out of PARK so
that the vehicle can be moved.

CAUTION!

• Do not use sling type equipment when towing.

Vehicle damage may occur.

• When securing the vehicle to a flat bed truck, do not

attach to front or rear suspension components. Dam-
age to your vehicle may result from improper towing.

• Ensure that the Electric Park Brake is released, and

remains released, while being towed.

Front-Wheel Drive (FWD) Models

The manufacturer recommends towing your vehicle with
all four wheels OFF of the ground using a flatbed.

If flatbed equipment is not available, this vehicle must be
towed with the front wheels OFF of 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.

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, extremely hot or cold
ambient temperatures will influence when the “Oil Change
Required” message is displayed. Severe Operating Condi-
tions can cause the change oil message to illuminate as
early as 3,500 miles (5,600 km) since last reset. Have your
vehicle serviced as soon as possible, within the next 500
miles (805 km).

Your 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
your authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” in “Understanding Your Instrument Panel” for
further information.

NOTE:

Under no circumstances should oil change inter-

vals exceed 10,000 miles (16,000 km), twelve 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.

Severe Duty All Models

Change Engine Oil at 4,000 miles (6,500 km) or 350 hours of
engine run time if the vehicle is operated in a dusty and off
road environment or is operated predominately at idle or
only very low engine RPM’s. This type of vehicle use is
considered Severe Duty.
