2007 DODGE GRAND CARAVAN Owners Manual

Operation of the rear system is quite simple. Begin by
rotating the rear system center control knob on the front
ATC control unit to the “REAR CONTROL” position, this
illuminates an “UNLOCK” symbol in the rear display.
Next, rotate the Rear Blower Control and the Rear Mode
Control to the “AUTO” positions. Select the temperature you would like the system to maintain by pressing the
Rear Temperature Control button. Once the desired tem-
perature is displayed, the system will achieve and main-
tain 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:

Rear Blower Control
The rear blower control, located in
the headliner near the center of
the vehicle has an “OFF”,
“AUTO” and a range of blower
speeds.
The rear blower control knob can be manually set to
“OFF” or any fixed blower speed by rotating the knob
from low to high. This allows the rear seat occupants to
control the volume of air circulated in the rear of the
vehicle. CAUTION!Interior air enters the Rear Automatic Temperature
Control System through an intake grille located in
the passenger side trim panel behind the third seat.
The heater outlets are located in the passenger side
trim panel just behind the sliding door. Do not block
or place objects directly in front of the inlet grille or
heater outlets. The electrical system could overload
causing damage to the blower motor.
Rear Temperature Control
To change the temperature in the rear of the vehicle, press
the temperature control button down for cold and up for
heated air.298 UNDERSTANDING YOUR INSTRUMENT PANEL

Rear Mode Control
The Rear Mode Control, located in
the headliner near the center of
the vehicle can be used to select
between Auto, Headliner, Bi-
Level and Floor modes.
Auto Mode
The rear system automatically maintains the correct
mode and comfort level desired by the rear seat occu-
pants.
Floor Mode
Air comes from the floor outlets. Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE: In many temperature positions, the bi-level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Headliner Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vane knob on the outlets to
one side will shut off the air flow.
Summer Operation
The engine cooling system in air conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene UNDERSTANDING YOUR INSTRUMENT PANEL 299

glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
To insure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to section 7, Maintenance
Procedures, of this manual for proper coolant selection.
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, select  defrost 
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.
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.300 UNDERSTANDING YOUR INSTRUMENT PANEL
