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:
• If fog or mist appears on the windshield or
side glass, select Defrost mode and in-
crease 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 cool-
ing 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 posi-
tion can be adjusted to desired user settings.
Pressing other settings will cause the MAX
A/C operation to switch to the selected set-
ting and MAX A/C to exit.
Recirculation
When outside air contains smoke, odors, or
high humidity, or if rapid cooling is desired,
you may wish to recirculate interior air by
pressing the Recirculation control button.
The recirculation indicator will illuminate
when this button is selected. Press the but-
ton a second time to turn off the Recircula-
tion mode and allow outside air into the
vehicle.NOTE:
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. On systems with
Manual Climate Controls, the Recirculation
mode is not allowed in Defrost mode to im-
prove window clearing operation. Recircula-
tion will be disabled automatically if this
mode is selected. Attempting to use Recircu-
lation while in this mode will cause the LED
in the control button to blink and then turn
off.
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 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.
• The temperature can be displayed in U.S. or Metric units by selecting the US/Metric
customer-programmable feature. Refer to
the “Customer Programmable Features —
Uconnect System Settings” in “Multime-
dia” in your Owner’s Manual on
jeep.com/en/owners/manuals 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
GETTING TO KNOW YOUR VEHICLE
50

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.
NOTE:
The system will not automatically sense the
presence of fog, mist or ice on the wind-
shield. DEFROST mode must be manually
selected to clear the windshield and side
glass.
Operating Tips
NOTE:
Refer to the chart at the end of this section
for suggested control settings for various
weather conditions.
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-
equate 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 obstructions
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.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact your autho-
rized dealer to service your cabin air filter,
and to have it replaced when needed.

• The gauge may take up to five seconds toupdate after adding a gallon or more of
Diesel Exhaust Fluid (DEF) to the DEF
tank. If you have a fault related to the DEF
system, the gauge may not update to the
new level. See your authorized dealer for
service.
• The DEF gauge may also not immediately update after a refill if the temperature of
the DEF fluid is below 12F (-11C). The
DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update
after a period of run time. Under very cold
conditions, it is possible that the gauge
may not reflect the new fill level for several
drives.

WARNING/INDICATOR
LIGHTS AND MESSAGES
IMPORTANT: The warning/indicator light
switches on in the instrument panel together
with a dedicated message and/or acoustic
signal when applicable. These indications
are indicative and precautionary and as such
must not be considered as exhaustive and/or
alternative to the information contained in
the Owner Manual, which you are advised to
read carefully in all cases. Always refer to the
information in this chapter in the event of a
failure indication.
All active telltales will display first, if appli-
cable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales are
optional and may not appear.
Red Telltale Lights
– Seat Belt Reminder Warning Light
When the ignition switch is first turned to
ON/RUN, this light will turn on for four to
eight seconds as a bulb check. During the
bulb check, if the driver's seat belt is unbuck- led, a chime will sound. After the bulb check
or when driving, if the driver’s seat belt re-
mains unbuckled, the Seat Belt Reminder
Light will flash or remain on continuously and
a chime will sound.
– Air Bag Warning Light
This light will turn on for four to eight sec-
onds as a bulb check when the ignition
switch is first turned to ON/RUN. If the light
is either not on during startup, stays on, or
turns on while driving, have the system in-
spected at an authorized dealer as soon as
possible. This light will illuminate with a
single chime when a fault with the Air Bag
Warning Light has been detected, it will stay
on until the fault is cleared. If the light comes
on intermittently or remains on while driving,
have an authorized dealer service the vehicle
immediately.
– Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
GETTING TO KNOW YOUR INSTRUMENT PANEL
80

indicate that the parking brake is applied,
that the brake fluid level is low, or that there
is a problem with the anti-lock brake system
reservoir.
If the light remains on when the parking
brake has been disengaged, and the fluid
level is at the full mark on the master cylinder
reservoir, it indicates a possible brake hy-
draulic system malfunction or that a problem
with the Brake Booster has been detected by
the Anti-Lock Brake System (ABS) / Elec-
tronic Stability Control (ESC) system. In this
case, the light will remain on until the condi-
tion has been corrected. If the problem is
related to the brake booster, the ABS pump
will run when applying the brake, and a brake
pedal pulsation may be felt during each stop.
The dual brake system provides a reserve
braking capacity in the event of a failure to a
portion of the hydraulic system. A leak in
either half of the dual brake system is indi-
cated by the Brake Warning Light, which will
turn on when the brake fluid level in the
master cylinder has dropped below a speci-
fied level.The light will remain on until the cause is
corrected.
NOTE:
The light may flash momentarily during sharp
cornering maneuvers, which change fluid
level conditions. The vehicle should have
service performed, and the brake fluid level
checked.
If brake failure is indicated, immediate repair
is necessary.
WARNING!
Driving a vehicle with the red brake light
on is dangerous. Part of the brake system
may have failed. It will take longer to stop
the vehicle. You could have a collision.
Have the vehicle checked immediately.
Vehicles equipped with the Anti-Lock Brake
System (ABS) are also equipped with Elec-
tronic Brake Force Distribution (EBD). In the
event of an EBD failure, the Brake Warning
Light will turn on along with the ABS Light.
Immediate repair to the ABS system is re-
quired. Operation of the Brake Warning Light can be
checked by turning the ignition switch from
the OFF position to the ON/RUN position.
The light should illuminate for approximately
two seconds. The light should then turn off
unless the parking brake is applied or a brake
fault is detected. If the light does not illumi-
nate, have the light inspected by an autho-
rized dealer.
The light also will turn on when the parking
brake is applied with the ignition switch in
the ON/RUN position.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake
application.
– Vehicle Security Light
This light will flash at a fast rate for approxi-
mately 15 seconds when the vehicle security
alarm is arming, and then will flash slowly
until the vehicle is disarmed.

WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the engine control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
– Electronic Stability Control (ESC)
Warning Light
The “ESC Indicator Light” in the instrument
cluster will come on when the ignition switch
is turned to the ON/RUN position. It should
go out when the engine is running. If the “ESC Indicator Light” comes on continuously
with the engine running, a malfunction has
been detected in the ESC system. If this light
remains on after several ignition cycles, and
the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see your authorized dealer as soon
as possible to have the problem diagnosed
and corrected.
• The “ESC Off Indicator Light” and the
“ESC Indicator Light” come on momen-
tarily each time the ignition switch is
turned to ON/RUN.
• Each time the ignition is turned to ON/ RUN, the ESC system will be ON, even if it
was turned off previously.
• The ESC system will make buzzing or clicking sounds when it is active. This is
normal; the sounds will stop when ESC
becomes inactive following the maneuver
that caused the ESC activation.
This telltale indicates that an ESC event is
active.
– Electronic Stability Control (ESC) OFF
Indicator Light — If Equipped
This light indicates the Electronic Stability
Control (ESC) is off.
– Tire Pressure Monitoring System
(TPMS) Warning Light
The warning light switches on and a message
is displayed to indicate that the tire pressure
is lower than the recommended value and/or
that slow pressure loss is occurring. In these
cases, optimal tire duration and fuel con-
sumption may not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in se-
quence.
IMPORTANT: Do not continue driving with one
or more flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp brak-
ing and steering. Repair immediately using
the dedicated tire repair kit and contact your
authorized dealer as soon as possible.

required. However, the conventional brake
system will continue to operate normally if
the “Brake System Warning Light” is not on.
If the “Anti-Lock Brake Warning Light” is on,
the brake system should be serviced as soon
as possible to restore the benefits of anti-lock
brakes. If the “Anti-Lock Brake Warning
Light” does not come on when the ignition is
turned to the ON/RUN mode, have the light
repaired as soon as possible.
Electronic Brake Control System
Your vehicle is equipped with an advanced
Electronic Brake Control system (EBC). This
system includes Electronic Brake Force Dis-
tribution (EBD), Anti-Lock Brake System
(ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Elec-
tronic Roll Mitigation (ERM). These systems
work together to enhance both vehicle stabil-
ity and control in various driving conditions.Your vehicle may also be equipped with
Trailer Sway Control (TSC), Ready Alert Brak-
ing (RAB), Rain Brake Support (RBS), Dy-
namic Steering Torque (DST), Hill Descent
Control (HDC), and Selec-Speed Control
(SSC).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the
braking torque between the front and rear
axles by limiting braking pressure to the rear
axle. This is done to prevent overslip of the
rear wheels to avoid vehicle instability, and to
prevent the rear axle from entering ABS be-
fore the front axle.
Brake System Warning Light
The red “Brake System Warning Light” will
turn on when the ignition is turned to the
ON/RUN mode and may stay on for as long as
four seconds.
If the “Brake System Warning Light” remains
on or comes on while driving, it indicates that
the brake system is not functioning properly
and that immediate service is required. If the“Brake System Warning Light” does not
come on when the ignition is turned to the
ON/RUN mode, have the light repaired as
soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emer-
gency braking situation by sensing the rate
and amount of brake application and then
applies optimum pressure to the brakes. This
can help reduce braking distances. The BAS
complements the anti-lock brake system
(ABS). Applying the brakes very quickly re-
sults in the best BAS assistance. To receive
the benefit of the system, you must apply
continuous braking pressure during the stop-
ping sequence, (do not “pump” the brakes).
Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake
pedal is released, the BAS is deactivated.
