2007 DODGE 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

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:
•It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
•The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the “Overhead Console-Customer Program-
mable Features” in Section 3 of this manual. To provide you with maximum comfort in the automatic
mode, during cold start-ups the blower fan will remain
off and “DELAY” will appear in the front ATC display
until the engine warms up. Also, an estimate of the time
remaining until the “DELAY” is over will appear peri-
odically in the display. However, the fan will engage
immediately if the defrost mode is selected or by rotating
the blower control to any fixed blower speed.
This feature may be disabled using the following proce-
dure:
•Press and hold the Heated Rear Window and Auto LO
buttons for 5 seconds.
•The “DELAY” symbol will flash to indicate that the
feature as been disabled.

This button turns the entire system ON/OFF. When the
system is turned on it will return to the previous settings.
Manual Operation
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. NOTE:
Each of these features operate independently
from each other. If any one feature is controlled manually,
the remaining features will continue to operate automati-
cally.
The left blower control knob can be set to any fixed
blower speed by rotating the knob from low to high. The
fan will now operate at a fixed speed until additional
speeds are selected or either the Auto HIor Auto LO 
buttons are pressed. This allows the front occupants to
control the volume of air circulated in the vehicle and
cancel the “AUTO” mode.
The operator can also select the direction of the air by
rotating the right mode control knob to one of the
following positions.

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.

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.
