2008 DODGE DURANGO Owners Manual

Automatic Control
The ATC system can maintain a steady comfort level in
various weather conditions with a simple operation:
²Select your desired temperature setting by pressing
the + or - side of the TEMP rocker switches. A digital
temperature setting for driver and passenger will be
displayed. The ATC system uses an infrared sensor
located in the overhead console to measure the tem-
perature of the driver and passengers. Based on the
sensor input, the system will automatically control
comfort by varying the temperature, fan speed, and
mode. This maintains a comfortable temperature, even
under changing conditions. It is important that objects
are not blocking the infrared sensor. It is also impor-
tant that objects are not used that may scratch or
damage it in any way.
Level Of Automatic Control
72ÉF (22ÉC) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation. It is
not necessary to move the temperature setting for cold or
hot vehicles. The system automatically adjusts the tem-
perature, mode and fan speed to provide comfort as
quickly as possible.
NOTE:In cold weather, the fan will not turn on in
AUTO mode until the engine coolant has warmed up
sufficiently. This is indicated by the WARM UP DELAY
message on the display.
NOTE:The temperature can be displayed in U.S. or
Metric by selecting the US/M customer programmable

feature. Refer to the9Overhead Console-Customer Pro-
grammable Features.9The mode will also be shown in the
display and will change as required during automatic
operation.
NOTE:The system can be put into recirculate mode
without affecting ATC operation. This will prevent out-
side air from entering the vehicle. Use this mode to
temporarily block out any outside odors, smoke, or dust.
Manual Control (ATC)
You also may choose to customize your comfort by
selecting the fan speed and mode manually. Turning the
fan speed knob or any mode button places the system
into manual operation.
While in manual operation there are six fan speeds
available and the choice of any mode. The airflow
temperature is adjusted automatically to maintain the
desired comfort level. You can adjust the temperature by
pressing the + or - TEMP rocker switches.
FAN Control
Use this knob to regulate the amount of air delivered
through the system in any mode you select. Rotation
of the knob to increase (clockwise) or decrease (counter-
clockwise) fan speed.
Air Conditioning Operation
Press this button to enable the air conditioning
system. Compressor operation is automatic when
you press the AUTO button and no snowflake is
shown. A snowflake indicates that the A/C system is
enabled. The snowflake will not be displayed in AUTO
mode even though the A/C system is enabled.
The compressor may operate at any temperature above
32ÉF (0ÉC).
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in
258 INSTRUMENT PANEL AND CONTROLS

engine speed or power may be noticed when the com-
pressor cycles. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
Recirculate Button
Press this button to recirculate the air inside the
vehicle. Outside air is prevented from entering
the vehicle. Use this mode to temporarily block
out any outside odors, smoke, dust or when
rapid cooling of the interior is required.
Manual control of Recirculation is possible only in Panel,
Floor, and Bi-Level modes. It will not operate in Mix, or
Defrost modes. The recirculation symbol will flash three
times indicating recirculation is not available in these
modes.NOTE:If the interior of the windows begin to fog, press
the recirculate button to return to outside air. Some
conditions will cause captured interior air to fog win-
dows when in recirculate mode.
Panel
Air flows through the outlets located in the instru-
ment panel. These outlets can be adjusted to direct
the airflow.
Floor (Heat)
Air flows primarily through the floor outlets lo-
cated under the instrument panel. A small amount
of air is directed through the defrost and side window
demister outlets.
Mix
Outside air flows in equal proportions through the
floor and defroster outlets.
INSTRUMENT PANEL AND CONTROLS 259

Bi-Level
Air flows through the outlets located in the instru-
ment panel and those located on the floor.
NOTE:There is a difference in temperature between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Defrost
Outside air is directed to the windshield through
the defroster outlet located at the base of the
windshield and side window demist outlets.
NOTE:The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes, even if
the A/C snowflake button has not been pressed. This
dehumidifies the air to help dry the windshield.
Rear Temperature Control (ATC)
The ªREARº button cycles through the following modes:
Rear Control from Front
This allows the driver or passenger to control the rear
blower speeds rotating the POWER / FAN knob and the
rear temperature using the pass/rear TEMP +/- rocker
switch. While in this mode, pressing the POWER/FAN
knob will turn the rear system off. Pressing the POWER/
FAN knob will turn the rear system back on.
NOTE:The display will show a9REAR9fan speed graph
and a9REAR9digital temp setting.
CONTROL IN REAR
This allows the passengers in the second row seats to
control the blower speed and temperature by means of
the rear control located in the rear of the center floor
console as described under the9Rear Zone Climate
Control.9
NOTE:The front display will show ªCONTROL IN
REAR.º
260 INSTRUMENT PANEL AND CONTROLS

REAR OFF

Operating Tips
Fast Cooldown
For a fast cooldown, set the blower fan to the highest
setting, set the mode control to the panel fresh position,
press the snowflake button to turn on the air condition-
ing, and drive with the windows open for the first few
minutes. Once the hot air has been expelled, close the
windows and set the mode selector to the Recirculation
panel or Recirculation Bi-level position. When a comfort-
able condition has been reached, choose a mode position

and adjust the temperature control and blower speed as
necessary to maintain comfort. For high humidity condi-
tions it may be necessary to remain in the Recirculation
mode to maintain comfort.
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it's rainy or humid. In most cases
turning on the Air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Interior fogging
on the windshield can be quickly removed by selecting
the defrost mode.Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant during summer to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50 %
concentration is recommended.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions. This will also prevent snow ingestion into the
ducts.
