2008 DODGE GRAND CARAVAN instrument panel

Only when the front control for the rear blower is in the
RRposition do the second seat occupants have control of
the rear blower speed.
The rear blower control, located in the rear overhead
console has an off position and a range of blower speeds.
This allows the second seat occupants to control the
volume of air circulated in the rear of the vehicle.
CAUTION!
Interior air enters the Manual Rear Zone Climate
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
When the blower knob on the front climate control unit is
set to any position other thanRR, the rear temperature
selection follows the setting of the rear temperature
control knob on the front climate control unit. The rear
mode selection follows the setting of the rear mode
control knob.
To change the temperature in the rear of the vehicle,
rotate the temperature control knob counterclockwise for
cold and clockwise for heated air.
When rear controls are locked by the front system, the
lock symbol on the temperature knob is illuminated and
the rear overhead adjustments are ignored.
The rear airflow modes will mirror the front unit opera-
tion. Rear PANEL mode is automatically selected when
the front control is in the PANEL mode. When the front
unit is in BI-LEVEL mode, airflow will be emitted from
both the upper and lower rear outlets. When the front

control is in FLOOR, DEFROST, or MIX modes, airflow
will be directed out of the rear floor outlets.
Rear Mode Control
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 vanes of the outlets to one
side will shut off the airflow.

The Infrared Three-Zone ATC System automatically
maintains the interior comfort level desired by the driver
and all passengers. This is accomplished by an infrared
sensor, located in the forward overhead console. Based
on the sensor input, the system automatically adjusts the
air temperature, the airflow volume, and amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.

Below the automatic control, the system selects the
appropriate mode (airflow outlets) and fan speed.Operation of the system is quite simple.
1. Press the AUTO button and the word AUTO will
illuminate in the front ATC display, along with three
temperatures for Driver's, Passenger, and Rear seats. The
system will then automatically regulate the amount of
airflow.
2. Next, adjust the temperature you would like the
system to maintain by adjusting the driver's, passenger,
and rear seat rotary temperature knobs. Once the desired
temperature is displayed, the system will achieve and
automatically maintain that comfort level.
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:
²It 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.
²The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the ªCustomer Programmable Featuresº 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
on low and the DELAY symbol will appear in the front
ATC display until the engine warms up. The fan will
engage immediately if the DEFROST mode is selected or
by rotating the blower control to any fixed blower speed.
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 pressing the upper front blower rocker
button. The fan will now operate at a fixed speed until
additional speeds are selected. 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 selecting
one of the following positions.

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 vanes of the center
outlets down, will close off the airflow from the center
outlets. The thumbwheel next to the outboard outlets can
be rotated to regulate or shut off the airflow from these
outlets.
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 keeping the windshield clear.
DEFROST Mode
Air comes from the windshield and side window
demist outlets. Use DEFROST mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE:While operating in the other modes, the system
will not automatically sense the presence of fog, mist or
ice on the windshield. DEFROST mode must be manually

and DEFROST modes to improve window clearing op-
eration. Recirculation will be disabled automatically if
these modes are selected. Recirculation will be disabled
automatically if these modes are selected.
