A/C Button
Push the A/C button to engage the Air Conditioning (A/C). An LED illuminates when the A/C

system is engaged.

MAX A/C Setting
Turn the temperature control knob to the MAX Air Conditioning (A/C) setting to engage MAX

Air Conditioning (A/C). This is the coldest setting.

Recirculation Button
Push 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.

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.
Modes Control
Turn the knob to adjust airflow distribution. The airflow distribution mode can be adjusted so

Climate Control Functions

Air Conditioning (A/C)

The Air Conditioning (A/C) button allows the operator to

turn the air conditioning system on and off. When the

system is turned on, cool dehumidified air flows through

the vents into the cabin.
For improved fuel economy, press the A/C button to turn

off the air conditioning off and adjust the blower and

airflow mode settings. Make sure to only select Panel,

Bi-Level, or Floor modes.

NOTE:
• If fog or mist appears on the windshield or windows,

select Defrost mode and increase the blower speed.

• If the air conditioning performance is lower than ex-

pected, there may a blockage. Gently clean the area

around the radiator with water.

MAX A/C

The MAX A/C setting provides the maximum cooling

performance.
Press the button to toggle between MAX A/C and your

prior setting. The button illuminates when MAX A/C is on.

In the MAX A/C setting, you can adjust the blower level

and mode position. Pressing other settings causes the MAX

A/C operation to switch to your desired setting.

Recirculation

The Recirculation button helps remove smoke, odors, or

high humidity from the cabin.
The indicator illuminates when Recirculation mode is on.

Press the button again to turn it off.

NOTE:

Using Recirculation in cold weather may cause the

windows to fog up and this mode may be unavailable on

the touchscreen.

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 Tempera-

ture 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 tempera-

ture is displayed, the system will achieve and automati-

cally maintain that comfort level.

GETTING TO KNOW YOUR VEHICLE

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 temperature settings for

cold or hot vehicles. The system automatically adjusts

the temperature, 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 fea-

ture. Refer to the “Uconnect Settings” in “Multimedia”

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

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. OAT

coolant (conforming to MS.90032) is recommended.

Winter Operation

To ensure the best possible heater and defroster perfor-

mance, make sure the engine cooling system is functioning

properly and the proper amount, type, and concentration

of coolant is used. Use of the Air Recirculation 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 dam-

age when the system is started again.

GETTING TO KNOW YOUR VEHICLE

Window Fogging

Vehicle windows tend to fog on the inside in mild, rainy,

and/or humid weather. To clear the windows, select De-

frost 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.

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
mild washing solution, wiping parallel to the heat-
ing 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 win-
dow.

• Keep all objects a safe distance from the window.

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 an authorized dealer to service your cabin

air filter, and to have it replaced when needed.

leave the key fob in or near the vehicle, or in a location
accessible to children. Occupants, particularly unat-
tended children, can become entrapped by the win-
dows while operating the power window switches.
Such entrapment may result in serious injury or death.

Your vehicle may exhibit wind buffeting with the windows

down in certain open or partially open positions. This is a

normal occurrence and can be minimized by adjusting the

window opening.

both tops being installed at the same time.
For your convenience, a tool kit is provided with your

vehicle located in the center console. This kit includes the

necessary tools required for the operations described in the

following sections. All pieces fit into the ratchet for easy

use.
