washer fluid.
CLIMATE CONTROLS
The Climate Control System allows you to regu -
late the temperature, air flow, and direction of
air circulating throughout the vehicle. The
controls are located on the touchscreen (if
equipped) and on the instrument panel below
the radio.
Manual Climate Control Overview
The Manual Temperature Controls consist of a
series of three outer rotary dials (blower speed,
temperature and mode) and three inner push
buttons (Recirculation, A/C, Rear Window
Defroster).
Manual Temperature Controls
WARNING!
Sudden loss of visibility through the
windshield could lead to a collision. You might
not see other vehicles or other obstacles. To
avoid sudden icing of the windshield during
freezing weather, warm the windshield with
the defroster before and during windshield
washer use.

Manual Climate Control Descriptions
Icon Description
A/C Button
Push the A/C button to engage the Air Conditioning (A/C). The A/C indicator illuminates when A/C is on.
Recirculation Button
Press and release this button to change the system between recirculation mode and outside air mode. The Recirculation
indicator and the A/C indicator illuminate when the Recirculation button is pressed. Recirculation can be used when
outside conditions such as smoke, odors, dust, or high humidity are present. Recirculation can be used in all modes except
for Defrost. Recirculation may be unavailable if conditions exist that could create fogging on the inside of the windshield.
The A/C can be deselected manually without disturbing the mode control selection. 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.
Front Defrost Mode
Turn the mode control 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 may 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). The Rear Defrost indicator illuminates when the rear window defroster is ON. The rear window defroster
automatically turns OFF after 15 minutes.
Temperature Control
Temperature Control regulates the temperature of the air forced through the climate system. The temperature increases as
you turn the temperature control knob clockwise. The temperature decreases as you turn the temperature control knob
counterclockwise.

Blower Control
Blower Control regulates the amount of air forced through the climate system. There are seven blower speeds available.
The blower speed increases as you turn the blower control knob clockwise from the lowest blower setting. The blower
speed decreases as you turn the blower control knob counterclockwise.
NOTE:
Depending on the configuration, your vehicle may be equipped with four blower speeds.
Mode Control
Turn the mode control 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 located below the air vents to shut off or adjust the amount of airflow from these
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 condi -
tioning 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 manu -
ally 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 radi -
ator), for an accumulation of dirt or insects.
Clean with a gentle water spray from the front
of the radiator and through the condenser.
Recirculation
In cold weather, use of Recirculation mode may
lead to excessive window fogging. The Recircu -
lation feature may be unavailable 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 improve window
clearing operation. Recirculation is disabled
automatically if this mode is selected.
Attempting to use Recirculation while in this
mode causes the LED in the control button to
blink and then turns 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) coolant that
meets the requirements of FCA Material Stan -dard MS.90032 and 50% water is recom
-
mended. Refer to “Fluids And Lubricants” in
“Technical Specifications” for proper coolant
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 conditioning system at idle for about
five minutes in the fresh air and high blower
setting. This will ensure adequate system lubri -
cation to minimize the possibility of compressor
damage 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 suffi -
cient heating. If side window fogging becomes 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 Mainte -
nance” for filter replacement instructions.
Operating Tips Chart
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 interior
surface of the window.
Keep all objects a safe distance from the
window.WEATHER CONTROL
