2013 JEEP WRANGLER instrument panel

DefrostAir is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE: The air conditioning compressor operates in Mix,
Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
Recirculation Control
Pressing the Recirculation Control button will
put the system in recirculation mode. This can
be used when outside conditions such as
smoke, odors, dust, or high humidity are pres-
ent. Activating recirculation will cause the LED in the
control button to illuminate. NOTE:
•
Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
• The use of the Recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Select
the outside air position for maximum defogging.
• The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or Bi-Level.
• The A/C can be deselected manually without disturb-
ing the mode control selection.
• When the ignition switch is turned to the LOCK
position, the recirculation feature will be cancelled.

Air Conditioning Control
Press this button to engage the Air Con-
ditioning. A light will illuminate when
the Air Conditioning system is engaged.
Rotating the dial left into the blue area of
the scale indicates cooler temperatures,
while rotating right into the red area
indicates warmer temperatures.
NOTE:The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.
• MAX A/C
For maximum cooling, turn on the A/C and recirculation
buttons at the same time.
• ECONOMY MODE
If economy mode is desired, press the A/C button to turn
OFF the indicator light and the A/C compressor. Then,
move the temperature control to the desired temperature.
Automatic Temperature Control (ATC) — If Equipped
Automatic Operation

Operation of the system is quite simple.
1. Turn the Mode Control knob (on the right) and theBlower Control knob (on the left) to AUTO.
NOTE: The AUTO position performs best for front seat
occupants only.
Dial in the temperature you would like
the system to maintain by rotating the
Temperature Control knob. Once the
comfort level is selected, the system will
maintain that level automatically using
the heating system. Should the desired
comfort level require air conditioning,
the system will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the “O” (OFF) position on the blower control stops the
system completely and closes the outside air intake. The recommended setting for maximum comfort is 72° F
(22° C) for the average person; however, this may vary.
NOTE:
•
The temperature setting can be adjusted at anytime
without affecting automatic operation.
• Pressing the Air Conditioning Control button while in
AUTO mode will cause the LED in the control button
to flash three times and then turn off. This indicates
that the system is in AUTO mode and requesting the
air conditioning is not necessary.
• 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 behind
the radiator and through the condenser. Fabric front
fascia protectors may reduce airflow to the condenser,
reducing air conditioning performance.

Blower Control
For full automatic operation or for
automatic blower operation, turn the
knob to the AUTO position. In manual
mode, there are seven blower speeds
that can be individually selected. In off
position, the blower will shut off.
Manual Operation
This system offers a full complement of manual override
features, which consist of Blower Preferred Automatic,
Mode Preferred Automatic, or Blower and Mode Pre-
ferred Automatic. This means the operator can override
the blower, the mode, or both. There is a manual blower
range for times when the AUTO setting is not desired.
The blower can be set to any fixed blower speed by
rotating the Blower Control knob (on the left).
NOTE:Please read the Automatic Temperature Control
Operation Chart that follows for details.

The operator can override the AUTO mode setting to
change airflow distribution by rotating the Mode Control
knob (on the right) to one of the following positions.
•Panel
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct airflow.
NOTE: The center instrument panel outlets can be aimed
so that they are directed toward the rear seat passengers
for maximum airflow to the rear.
• Bi-Level
Air is directed through the panel and floor outlets.
NOTE: For all settings, except full cold or full hot, there
is a difference in temperature between the upper and
lower outlets. The warmer air flows to the floor outlets.
This feature gives improved comfort during sunny but
cool conditions. •
Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and
side window demist outlets.
• Mix
Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield.
• Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.4

•Air Conditioner Control
Press this button to turn on the air
conditioning during manual operation
only. When the air conditioning is
turned on, cool dehumidified air will
flow through the outlets selected with
the Mode control dial. Press this but-
ton a second time to turn OFF the air
conditioning. An LED in the button illuminates when
manual compressor operation is selected.
• Recirculation Control
The system will automatically control recircu-
lation. However, pressing the Recirculation
Control button will put the system in recircu-
lation mode. This can be used when outside
conditions such as smoke, odors, dust, or high humidity
are present. Activating recirculation will cause the LED in
the control button to illuminate. NOTE:
•
When the ignition switch is turned to the LOCK
position, the recirculation feature will be cancelled.
• In cold weather, use of the Recirculation mode may
lead to excessive window fogging. The Recirculation
mode is not allowed in the defrost mode in order to
improve window clearing. Recirculation will be dis-
abled automatically if in defrost mode.
• Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the Recirculation button to return to outside air.
Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper
visibility. For this reason, the system will not allow
recirculation to be selected while in defrost mode.
Attempting to use recirculation while in these modes
will cause the LED in the control button to blink and
then turn off.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
mode by pressing the Recirculation button. However,
under certain conditions, while in Automatic mode,
the system is blowing air out the defrost vents. When
these conditions are present, and the Recirculation
button is pressed, the indicator will flash and then turn
off. This tells you that you are unable to go into
Recirculation mode at this time. If you would like the
system to go into Recirculation mode, you must first
move the Mode knob to Panel, Bi-Level and then press
the Recirculation button. This feature reduces the
possibility of window fogging.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 in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A solution of 50% OAT
(Organic Additive Technology) coolant that meets the
requirements of Chrysler Material Standard MS-12106
and 50% water is recommended. Refer to “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection.
