2019 JEEP CHEROKEE overheating

(button on the touchscreen greyed out) if
conditions exist that could create fogging on
the inside of the windshield.
Automatic Temperature Control (ATC) —
If Equipped
Automatic Operation
1. Push the AUTO button on the faceplate,
or the AUTO button on the touchscreen on
the Automatic Temperature Control (ATC)
Panel.
2. Next, adjust the temperature you would
like the system to maintain by adjusting
the driver and passenger temperature
control buttons. Once the desired tem-
perature is displayed, the system will
achieve and automatically maintain that
comfort level.
3. When the system is set up for your comfort
level, it is not necessary to change the
settings. You will experience the greatest
efficiency by simply allowing the system
to function automatically.NOTE:
• It is not necessary to move the temperature
settings for cold or hot vehicles. The system
automatically adjusts the temperature,
mode, and blower speed to provide comfort
as quickly as possible.
• The temperature can be displayed in U.S.
or Metric units by selecting the US/Metric
customer-programmable feature. Refer to
the “Uconnect Settings” in “Multimedia”
in your Owner’s Manual for further
information.
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the
blower fan will remain on low until the engine
warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to pro-
vide proper corrosion protection and to pro-
tect against engine overheating. OAT coolant
(conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and de-
froster performance, make sure the engine
cooling system is functioning properly and
the proper amount, type, and concentration
of coolant is used. Use of the Air Recircula-
tion mode during Winter months is not rec-
ommended, because it may cause window
fogging.
Vacation/Storage
Before you store your vehicle, or keep it out of
service (i.e., vacation) for two weeks or more,
run the air conditioning system at idle for
about five minutes, in fresh air with the
blower setting on high. This will ensure ad-
GETTING TO KNOW YOUR VEHICLE

Extreme Cold Weather (Below –22°F Or
−30°C)
To ensure reliable starting at these tempera-
tures, use of an externally powered electric
engine block heater (available from an autho-
rized dealer) is recommended.
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.
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
WARNING!
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.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.
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 re-
peating start procedure.
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 bat-
tery blankets are available from your autho-
rized Mopar dealer.
STARTING AND OPERATING
140

CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’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 dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
REFUELING IN EMERGENCY
Emergency Fuel Filler Door Release
If you are unable to open the fuel filler door,
use the fuel filler door emergency release.
1. Open the liftgate.
2. Remove access door located on right inte-
rior trim panel for release cable with the
tip of your key.
3. Grab the release cable tether and pull up
to release the fuel filler door.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating your en-
gine by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease engine idle speed.
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 con-
ditioner turned off until the pointer drops
back into the normal range. If the pointer
remains on the “H” and you hear continu-
ous chimes, turn the engine off immedi-
ately and call for service.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.
• 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.
IN CASE OF EMERGENCY
212

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 tem-
porarily 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 ac-
cess hole (at the left 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.
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 transmission, push
and hold the lock button on the gear selector.
Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or
SECOND GEAR and REVERSE (with manual
transmission), while gently pressing the ac-
celerator.
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 sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating 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 shift-
ing between DRIVE/SECOND GEAR 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 dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).

NOTE:
The rear wiper arm cannot be fully raised
off the glass unless the wiper arm pivot
cap is unsnapped first. Attempting to fully
raise the rear wiper arm without unsnap-
ping the wiper arm pivot cap may damage
the vehicle.
2. Lift the rear wiper arm fully off the glass.
3. Insert the wiper blade pivot pin into the
opening on the end of the wiper arm. Grab
the bottom end of the wiper arm with one
hand, and apply pressure on the wiper
blade flush with the wiper arm until it
snaps into place.
4. Lower the wiper blade onto the glass and
snap the wiper arm pivot cap back into
place.
RAISING THE VEHICLE
In the case where it is necessary to raise the
vehicle, go to an authorized dealer or service
station.
TIRES
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
WARNING!
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle control.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure.
Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
