CHRYSLER PACIFICA 2006 1.G Owners Manual

NOTE:
•The compressor will not engage until the engine has
been running for a few seconds.
•If your air conditioning performance seems lower than
expected, check the A/C air filter (ATC equipped
vehicles only) and the front of the A/C condenser for
an accumulation of dirt or insects. The A/C condenser
is located in front of the radiator. The A/C air filter is
located under the instrument panel on the passenger
side.
•Fabric type fascia protectors tend to block the amount
of air to the condenser and may reduce air condition-
ing performance.
Economy Mode
If economy mode is desired, press the A/C button to turn
off the indicator light, and the A/C compressor. Move the
temperature control lever to the desired temperature.
Recirculation Control
Press the recirculation button to recirculate the
air inside the vehicle. This is located next to the
A/C button. An indicator light on the button
shows that air is being recirculated. Use the
recirculation mode to rapidly cool the inside of the
vehicle. The recirculation mode can also be used to
temporarily block out outside odors, smoke, and dust.
NOTE:
•When the ignition switch is turned OFF, the recircula-
tion feature will be cancelled.
•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.

•If the recirculation button is pressed while in the Mix
or Defrost mode, the indicator light in the recirculation
button will flash 3 times indicating that recirculation is
not allowed.
A/C Recirculation Programming
The recirculation control is programmed to cancel the
recirculation mode when the ignition key is turned OFF
and will reset to outside air mode when the ignition key
is turned ON. The frequent use of outside air will help
keep odors from building up within the air conditioner-
heater housing. It is recommended that the recirculation
mode be used as little as possible, especially in humid
climates.
For hot and dry climates, or people who are allergic to
pollen and find frequent use of the recirculation mode
necessary, the recirculation mode can be programmed to
not automatically reset to the outside mode by using the
following procedures:
•Turn the ignition switch to the OFF position.
•Set the mode control to “PANEL”.
•Depress and hold in the “POWER” button.
•Start the engine, and continue to hold in the “POWER”
button until the indicator light starts flashing repeat-
edly.
•Press the recirculation button until the indicator light
remains lit.
•The selection will be stored when the ignition switch is
turned OFF or if the “POWER” button is pressed.
If the recirculation indicator light is lit, the recirculation
mode will not reset when the engine is started. If the
recirculation indicator light is not lit, the recirculation
mode will reset to the outside air mode when the engine
is started. The programmed status can be changed back
and forth by following the above mentioned procedure.

Dual-Zone Automatic Temperature Control
The Dual Zone Automatic Temperature Control (ATC)
System automatically maintains the interior comfort level
desired by the driver and front seat passenger. This is
accomplished 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 front seat passenger. Based on the
sensor input, the system automatically adjusts the air
temperature, the airflow volume, the airflow distribu-
tion, and amount of inside air recirculation to maintain
front seat occupant comfort, even under changing out-
side weather conditions. To operate the system, press either the AUTO HIor
 AUTO LO buttons. The system now automatically
regulates the heating and air conditioning system includ-
ing blower speed, outlet air temperature, and airflow
distribution through the various outlets within the in-
strument panel. Using the TEMPbuttons, adjust the

temperature you would like the system to maintain.
When the system is set to your comfort level, it is not
necessary to change the settings. You will experience the
greatest efficiency by allowing the system to function
automatically. The system will operate fully automati-
cally in either AUTO HIorAUTO LO. The AUTO
LO  setting will limit the maximum fan speed and should
be used when more quiet operation is desired. Use the
 AUTO HI setting when the quickest cool-down or
warm-up performance is desired.
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 “Electronic Vehicle Information Center-
Customer Programmable 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 display until the
engine warms up. An estimate of the time remaining
until the “DELAY” is complete will appear periodically
in the display. However, the fan will engage immediately
if the defrost mode is selected or by pushing the blower
switch and manually adjusting the fan 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.

Power Button
This button turns the entire system ON/OFF. When the
system is turned on it will return to the previous settings.
Dual/Single Zone Operation
When DUAL is displayed in the ATC control unit, the
driver and passenger air outlet temperatures can be
individually adjusted from the two independent TEMP
buttons. When a front seat passenger is not present,
pressing the DUALbutton will match the passenger’s
temperature setting to the driver’s temperature setting.
This will help equalize air outlet temperatures across the left and right side of the instrument panel. The outside
temperature will replace the passenger’s temperature
setting in the display. Pressing the
DUALbutton a
second time or adjusting the passenger’s TEMPbutton
will return the system to dual independent temperature
operation.
Manual Operation
This system offers a full complement of manual override
features. The indicator light in both the AUTO HIor
 AUTO LO buttons will turn off when the system is
being used in the manual mode. The fan speed, airflow
distribution, and outside air/recirculated air can be
manually adjusted.
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 front blower control can be set to any fixed
blower speed by pressing the rocker switch up or
down. This allows the front occupants to control the
volume of air circulated in the vehicle and cancel the auto
mode. The fan will now operate at a fixed speed until
additional speeds are selected or until either the AUTO
HI  orAUTO LO buttons are pressed. The system will
continue to automatically adjust air temperature and
airflow distribution.
The operator can also select the direction of the air by
pressing the mode control rocker switch located to the
left of the A/C button and 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
