air condition DODGE GRAND CARAVAN 2013 5.G User Guide

6. Mix Mode
Air is directed through the floor, defrost and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort,
while reducing moisture on the windshield.
7. Front Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use Defrost mode with
maximum blower and temperature settings for best
windshield and side window defrosting.
NOTE:The air conditioning compressor may operate in
Mix and Defrost, or a blend of these modes even if the
A/C button is not pressed. This dehumidifies the air to
help dry the windshield. To improve fuel economy, use
these modes only when necessary.8. Electronic Rear Window Defrost
Press this button to turn on the rear window
defroster and the heated outside mirrors (if
equipped). An indicator in the button will illuminate
when the rear window defroster is on. The rear window
defroster automatically turns off after approximately
10 minutes.
NOTE:
•You can turn off the heated mirror feature at anytime
by pressing the rear window defroster switch a second
time.
•To prevent excessive battery drain, use the rear win-
dow defroster only when the engine is operating.

•Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
•In cold or damp weather, the use of the Recirculation
mode will cause windows to fog on the inside because
of moisture buildup inside the vehicle. For maximum
defogging, select the outside air position.
•In order to prevent fogging, when the Recirculation
button is pressed and the mode control is set to Panel,
the A/C will engage automatically.
•The A/C can be deselected manually without disturb-
ing the mode control selection.
10. Air Conditioning (A/C) Button
Press and release to change the current setting.
The indicator illuminates when ON.NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser (located in front of the radiator), for an accumu-
lation of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce airflow to the
condenser, reducing air conditioning performance.
11. Floor Mode Button
Air is directed through the floor outlets with a
small amount through the defrost and side win-
dow demist outlets.
12. Bi-Level Mode Button
Air is directed through the panel and floor outlets.

conditions other than full cold or full hot), between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
13. Panel Mode Button
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted for
direction, and turned on or off to control airflow.

Automatic Temperature Control (ATC) — If
Equipped
•Front Three-Zone ATC allows both driver and front
passenger seat occupant, and rear seat occupants to
select individual comfort settings.
•When occupants in the vehicle select the AUTO mode
operation, a comfort temperature can be set by using
the temperature up and down buttons, and the auto
blower operation will be set automatically.
•The system can be controlled manually, if desired.
•SYNC feature links the controls for all three zones,
allowing one comfort setting (driver setting) for the
cabin, if desired.
The Three-Zone ATC system automatically maintains the
interior comfort level desired by the driver and all passen-
gers. The system automatically adjusts the air temperature,the airflow volume, amount of outside air recirculation and
the airflow direction. This maintains a comfortable tem-
perature, even under changing conditions.Front ATC Panel

can be turned off, but the A/C system shall remain active
to prevent fogging of the windows.
•If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed.
Rear Automatic Temperature Control (ATC) — If
Equipped
The rear ATC system has floor air outlets at 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 headliner outlets.
The rear system temperature control is on the front ATC
panel located on the instrument panel.
Pressing the Rear Temperature Lock button on the front
ATC panel, illuminates a lock symbol in the rear display.

Recirculation Control
When outside air contains smoke, odors, or high
humidity, or if rapid cooling is desired, you may
wish to recirculate interior air by pressing the
Recirculation control button. Recirculation mode
should only be used temporarily. The recirculation LED will
illuminate when this button is selected. Push the button a
second time to turn off the Recirculation mode LED and
allow outside air into the vehicle.
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 protectagainst engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for proper coolant selection.
Winter Operation
To ensure 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 “Maintenance
Procedures” in “Maintaining Your Vehicle” for proper
coolant selection. Use of the air Recirculation mode
during Winter months is not recommended, because it
may cause window fogging.
452 UNDERSTANDING YOUR INSTRUMENT PANEL

Vacation/Storage
Before you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes, in
fresh air with the blower setting on high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild, rainy
and/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.

A/C Air Filter
On vehicles equipped with Automatic Temperature Con-
trol (ATC), the climate control system filters out dust and
pollen from the air. Refer to “Air Conditioning” in “Main-
taining Your Vehicle” for filter replacement instructions.
