2007 DODGE GRAND CARAVAN Owners Manual

The rear temperature knob and the rear blower speed can
be adjusted as desired by the second seat occupants.
Automatic Temperature Control — If Equipped
The Infrared Three-Zone Automatic Temperature Control
System automatically maintains the interior comfort level
desired by the driver and all passengers. This is accom-
plished by using two infrared sensors, located in the
center of the instrument panel. The two infrared sensors
independently measure the surface temperature of the
driver and passenger. Based on the sensor input, the
system automatically adjusts the air temperature, the air
flow volume, and amount of outside air recirculation.
This maintains a comfortable temperature even under
changing conditions. Operation of the system is quite simple. Begin by press-
ing the auto rocker switch to the “HI” or “LO” position,
the word “AUTO” will illuminate in the front ATC
display along with “HI” or “LO”. The system will then
automatically regulate the amount of air flow. Next, dial
in the temperature you would like the system to maintain
by pressing the driver’s or passenger’s temperature con-
trol button. The rear temperature can only be adjusted
from the front when the “REAR SYSTEM” knob on the Three-Zone Automatic Temperature Control UNDERSTANDING YOUR INSTRUMENT PANEL 289

front ATC unit is in the “AUTO” position. Once the
desired temperature is displayed, the system will achieve
and maintain that comfort level automatically. 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:

This feature may be enabled using the following proce-
dure:

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. Moving the air vane knob on the center
outlets down, will close off the air flow from the center
outlets. The thumbwheel next to the outboard outlets can
be rotated to regulate or shut off the air flow from these
outlets.
Panel Outlets292 UNDERSTANDING YOUR INSTRUMENT PANEL

Bi-Level Mode Air comes from both the instrument panel outlets, floor
outlets and defrost. A slight amount of air is also directed
through the side window demister outlets.
NOTE: In many temperature positions, the bi-level
mode is designed to provide cooler air out of the panel
outlets and warmer air from the floor outlets.

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
Air comes from the floor, defrost and side window
demist outlets. This mode works best in cold or snowy
conditions. It allows you to stay comfortable while keep-
ing the windshield clear.Floor Outlets Mix Outlets294 UNDERSTANDING YOUR INSTRUMENT PANEL

Defrost Mode
Air comes from the windshield and side window demist
outlets. Use this setting when necessary to defrost your
windshield and side windows.
NOTE: While operating in either  Auto HI  or  Auto
LO  , the system will not automatically sense the presence of fog, mist, or ice on the windshield.  Defrost  mode
must be manually selected to clear the windshield and
side glass.
The  snowflake  or  a/c  button allows the opera-
tor to manually activate or deactivate the air
conditioning system. When the snowflake symbol
in the ATC display is on, cool, dehumidified air flows
through the air outlets. If economy mode is desired, press
the snowflake button to turn off the snowflake icon in the
ATC display and deactivate the air conditioning system.
Note: While operating in  auto hi  or  auto lo  , the air
conditioning system is always activated. If fog, or mist
appears on the windshield or side glass, select  defrost 
mode and increase blower speed.
Recirculation Control
When outside air contains smoke, odors, high
humidity, or if rapid cooling is desired, you
may wish to recirculate interior air by pressingDefrost Outlets UNDERSTANDING YOUR INSTRUMENT PANEL 295

the recirculation button. The recirculation mode should
only be used temporarily. The recirculation symbol will
illuminate in the display when this button is selected.
Push the button a second time to turn off the recirculation
icon in the display and allow outside air into the vehicle.
NOTE: In cold weather, use of the Recirculation mode
may lead to excessive window fogging. The Recirculation
mode is not allowed in the Mix and Defrost modes to
improve window clearing operation. Recirculation will
be disabled automatically if these modes are selected.
Rear Automatic Temperature Control — If
Equipped
The Rear Automatic Temperature Control System has
floor air outlets to the rear of the right side sliding door
and overhead outlets at each outboard rear seating
position. The system provides heated air through the
floor outlets or cool, dehumidified air through the head-
liner outlets. The “REAR SYSTEM” knob for the Rear Automatic
Temperature Control System is on the front ATC control
unit located on the instrument panel.
Selecting the “AUTO” position for the Rear Automatic
Temperature Control System from the front ATC control
unit, illuminates a “LOCK” symbol in the rear display.
The rear temperature and air source are controlled from
the front ATC control unit.
The “REAR SYSTEM” knob on the front ATC control unit
has three positions, “REAR CONTROL”, “OFF”, and
“AUTO”. Only when the “REAR SYSTEM” knob is in the
“REAR CONTROL” position do the second seat occu-
pants have control of the Rear Automatic Temperature
Control System.
The Rear Automatic Temperature Control System is
located in the headliner near the center of the vehicle.296 UNDERSTANDING YOUR INSTRUMENT PANEL
