2012 Ram Cargo Van air conditioning

If you ever wish to interrupt the system while it lists
options, press the Voice Command
button, listen
for the beep, and say your command.
Pressing the Voice Command
button while the
system is speaking is known as “barging in.” The system
will be interrupted, and after the beep, you can add or
change commands. This will become helpful once you
start to learn the options.
NOTE: At any time, you can say the words “Cancel”,
“Help” or “Main Menu”.
These commands are universal and can be used from any
menu. All other commands can be used depending upon
the active application.
When using this system, you should speak clearly and at
a normal speaking volume. The system will best recognize your speech if the win-
dows are closed, and the heater/air conditioning fan is
set to low.
At any point, if the system does not recognize one of your
commands, you will be prompted to repeat it.
To hear the first available Menu, press the Voice Com-
mand
button and say “Help” or “Main Menu”.
Commands
The Voice Command system understands two types of
commands. Universal commands are available at all
times. Local commands are available if the supported
radio mode is active.
Changing the Volume
1. Start a dialogue by pressing the Voice Command
button.
2. Say a command (e.g., “Help”).

CLIMATE CONTROLS
The Climate Control system allows you to regulate the
temperature, amount, and direction of air circulating
throughout the vehicle. The controls are located on the
instrument panel, below the radio.
Manual Heating And Air Conditioning System —
If Equipped
The controls for the manual system in this vehicle contain
a series of outer rotary dials and inner push knobs. These
comfort controls can be set to obtain desired interior
conditions.
With the Three-Zone Temperature Control system, each
front seat occupant can independently control the Heat-
ing, Ventilation, and Air Conditioning operations coming
from the outlets on their side of the vehicle.
The primary control for the rear blower is on the front
climate control unit located on the instrument panel.
When the front control is in any position other than rear,
the front control operates all the rear functions.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.

7. Front Defrost ModeAir 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. For an additional five minutes of operation,
press the button a second time. 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.
CAUTION!
Failure to follow these cautions can cause damage to
the heating elements:
•Use care when washing the inside of the rear
window. Do not use abrasive window cleaners on
the interior surface of the window. Use a soft cloth
and a mild washing solution, wiping parallel to
the heating elements. Labels can be peeled off
after soaking with warm water.

•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 window
demist outlets.
12. Bi-Level Mode Button Air is directed through the panel and floor outlets.
NOTE: There is a difference in temperature (in any
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 instrument
panel. These outlets can be adjusted for direction,
and turned on or off to control airflow.

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.1. Air Conditioning (A/C) Button

(A/C) setting, the indicator illuminates when A/C is ON.
Performing this function will cause the ATC to switch
into manual mode.

UNDERSTANDING YOUR INSTRUMENT PANEL 401

Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When in A/C mode and the ATC is set to a cool
temperature, dehumidified air flows through the air
outlets. If Economy mode is desired, press the A/C
button to turn off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•If the system is in Mix, Floor or Defrost Mode, the A/C
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.
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. Re-
circulation mode should only be used temporarily. A LED
will illuminate on the Recirculation control button when
Recirculation mode is selected. Push the button a second
time to turn off the Recirculation mode LED and allow
outside air into the vehicle.
NOTE: In cold weather, use of the Recirculation mode
may lead to excessive window fogging. The Recirculation
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled auto-
matically if this mode is selected.

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.
