Recirculation Button
Press and release this button to change the system between recirculation mode and outside air
mode. Recirculation can be used when outside conditions such as smoke, odors, dust, or high
humidity are present.
NOTE:
•Continuous use of the Recirculation mode may make the inside air stuffy and window fog-
ging may occur. Extended use of this mode is not recommended.
•The use of the Recirculation mode in cold or damp weather could cause windows to fog on
the inside, because of moisture buildup inside the vehicle. Select the outside air position for
maximum defogging.
•Recirculation can be used in all modes except for Defrost.
•The A/C can be deselected manually without disturbing the mode control selection.
Front Defrost Mode
Turn the Knob to the Front Defrost position. Air comes from the windshield and side window
demist outlets. When the defrost button is selected, the blower level will increase. Use Defrost
mode with maximum temperature settings for best windshield and side window defrosting and
defogging.
Rear Defrost Button
Push and release the Rear Defrost Control button to turn ON the rear window defroster and the
heated outside mirrors (if equipped). An indicator will illuminate when the rear window de-
froster is ON. The rear window defroster automatically turns OFF after ten minutes.

Temperature Control
Use this control to regulate the temperature of the air inside the passenger compartment. Rotat-
ing the knob counterclockwise, from top center into the blue area of the scale, indicates cooler
temperatures. Rotating the knob clockwise, into the red area, indicates warmer temperatures.
Blower Control
There are seven blower speeds. Use this control to regulate the amount of air forced through the
system in any mode you select. The blower speed increases as you move the control clockwise
from the OFF position.
NOTE:Depending on the configuration, your vehicle may be equipped with four blower
speeds.
Modes Control
Turn the knob to change the airflow distribution mode. The airflow distribution mode 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 lo-
cated 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.
Floor Mode
Floor Mode
Air comes from the floor outlets. A slight amount of air is directed through the defrost and side
window demister outlets.
Mix Mode
Mix Mode
Air is directed through the floor, defrost, and side window demister 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.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
• Use care when washing the inside of the rear win-
dow. Do not use abrasive window cleaners on the
interior surface of the window. Use a soft cloth and a

Additional Rear Climate Control — If Equipped
This switch, mounted on the instrument panel to the left of
the steering column, activates the additional rear heating/
air conditioning system vent.
NOTE:The switch must be enabled for operation by the
Upfitter.
Climate Control Functions
A/C (Air Conditioning)
The Air Conditioning (A/C) button allows the operator to
manually activate or deactivate the air conditioning sys-
tem. When the air conditioning system is turned on, cool
dehumidified 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 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.
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 button a second time to turn off the
Recirculation mode and allow outside air into the vehicle.
NOTE:In cold weather, use of recirculation mode may lead
to excessive window fogging. On systems with Manual
Climate Controls, the Recirculation mode is not allowed in
Defrost mode to improve window clearing operation.
Recirculation will be disabled automatically if this mode is
selected. Attempting to use Recirculation while in this
mode will cause the LED in the control button to blink and
then turn off.
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 provide proper corrosion
protection and to protect against engine overheating. A
solution of 50% OAT (Organic Additive Technology) cool-
ant that meets the requirements of FCA Material Standard MS.90032 and 50% water is recommended. Refer to “Dealer
Service” in “Servicing And Maintenance” for proper cool-
ant selection.
Winter Operation
Use of the air Recirculation mode during winter months is
not recommended because it may cause window fogging.
Vacation Storage
Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh air
and high blower setting. This will ensure adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly removed
by turning the mode selector to Defrost. The Defrost/Floor
mode can be used to maintain a clear windshield and
provide sufficient heating. If side window fogging be-
comes a problem increase blower speed. Vehicle windows
tend to fog on the inside in mild but rainy or humid
weather.

NOTE:Recirculate without A/C should not be used 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.
A/C Air Filter
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be totally
filtered out. Refer to “Dealer Service” in “Servicing and
Maintenance” for filter replacement instructions.

WINDOWS
Power Windows
The control on the left front door panel has up-down
switches that give you fingertip control of all power
windows. There is a single opening and closing switch on
the front passenger door for passenger window control.
NOTE:The Key Off Power Delay feature will allow the
power windows to operate for up to three minutes after the
ignition is turned OFF. This feature is cancelled when
either front door is opened.
WARNING!
• Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing children to
be 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. A child could oper-
ate power windows, other controls, or move the
vehicle.
