Mode Control
Select one of the Mode buttons on the touchscreen or press the Mode button on the faceplate to adjust the airflow
distribution. The airflow distribution can be adjusted so air comes from the instrument panel outlets, floor outlets,
defrost outlets, and demist outlets.
The Mode settings are as follows:
Panel Mode Panel Mode Air comes from the outlets in the instrument panel. Each of these outlets can be individually adjusted to direct the
flow of air. The air vanes of the center outlets and outboard outlets can be moved up and down or side to side to
regulate airflow direction. There is a shut off wheel located below the air vanes to shut off or adjust the amount of
airflow from these outlets.
Bi-Level Mode Bi-Level Mode Air comes from the instrument panel outlets and floor outlets. A slight amount of air is directed through the defrost
and side window demister outlets.
NOTE:
Bi-Level mode is designed under comfort conditions to provide cooler air out of the panel outlets and warmer air
from the floor outlets.

Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the
operator to manually activate or deactivate
the air conditioning system. When the air
conditioning system is turned on, cool dehu-
midified air will flow through the outlets into
the cabin. For improved fuel economy, press
the A/C button to turn off the air conditioning
and manually adjust the blower and airflow
mode settings. Also, make sure to select only
Panel, Bi-Level, or Floor modes.
NOTE:
For Manual Climate Controls, if the system
is in Mix, Floor or Defrost Mode, the A/C
can be turned off, but the A/C system shall
remain active to prevent fogging of the
windows.
If fog or mist appears on the windshield or
side glass, select Defrost mode, and
increase blower speed if needed.
If your air conditioning performance
seems lower than expected, check the
front of the A/C condenser (located in front
of the radiator), for an accumulation of dirt or insects. Clean with a gentle water spray
from the front of the radiator and through
the condenser.
MAX A/C
MAX A/C sets the control for maximum
cooling performance.

Press and release to toggle between MAX A/C
and the prior settings. The button illuminates
when MAX A/C is on.

In MAX A/C, the blower level and mode position
can be adjusted to desired user settings.
Pressing other settings will cause the MAX A/C
operation to switch to the selected setting and
MAX A/C to exit.

Recirculation
In cold weather, use of Recirculation mode
may lead to excessive window fogging. The
Recirculation feature may be unavailable
(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 that you would like the system to maintain by
adjusting the driver and passenger
temperature control buttons. Once the
desired temperature 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 tempera-
ture settings for cold or hot vehicles. The
system automatically adjusts the tempera-
ture, mode, and blower speed to provide
comfort as quickly as possible.
2020_JEEP_JL_WRANGLER_UG_RHD_UK.book Page 44

The temperature can be displayed in U.S.
or Metric units by selecting the U.S./
Metric customer-programmable feature.
Refer to the “Uconnect Settings” in
“Multimedia” in the 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 provide proper corrosion protec -
tion and to protect against engine over -
heating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and
defroster 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
recommended, 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
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc -
tions, such as leaves. Leaves collected in the
air intake may reduce airflow, and if they
enter the plenum, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled
off after soaking with warm water.
Do not use scrapers, sharp instruments,
or abrasive window cleaners on the inte-
rior surface of the window.
Keep all objects a safe distance from the
window.

WARNING!

Never leave children unattended in a vehicle,
and do not let children play with power
windows. Do not leave the key fob in or near

Wind Buffeting
Wind buffeting can be described as the
perception of pressure on the ears or a heli-
copter-type sound in the ears. Your vehicle
may exhibit wind buffeting with the windows
down in certain open or partially open posi -
tions. This is a normal occurrence and can be
minimized by adjusting the window opening.
