2011 Ram 5500 Chassis Cab air conditioning

NOTE:If you do not say a command within a few
seconds, the system will present you with a list of
options.
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. For example, if you are in the disc menu and you are
listening to FM radio, you can speak commands from the
disc menu or from the FM radio menu.
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
Command
button and say “Help” or “Main
Menu”.

higher temperatures than the outside ambient tempera-
ture. The higher displayed temperature is due to blocked
or reduced airflow to the underhood ambient tempera-
ture sensor caused by the snowplow. In addition, on
vehicles equipped with Automatic Temperature Control
(ATC), it is suggested that the interior cabin temperature
be manually controlled should the system not perform as
desired while in automatic mode. Both the outside tem-
perature display and ATC operation will return to nor-
mal when the snowplow is removed.
Manual Heating and Air Conditioning System
The controls for the manual heating and air conditioning
system in this vehicle consist of a series of outer rotary
dials and inner push knobs. These comfort controls can
be set to obtain desired interior conditions.1 – Front Blower4 – DEFROST Mode

Front Blower Control
There are four blower speeds. Use this
control to regulate the amount of air
forced through the system in any
mode you select. The blower speed
increases as you move the control
clockwise from the OFF position.
NOTE: For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the blower control is left in the OFF position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. Rotating the knob coun-
terclockwise, from top center into the
blue area of the scale, indicates cooler temperatures. Rotating the knob clockwise, into the red
area, indicates warmer temperatures.
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.
Mode Control (Air Direction)
Mode control allows you to choose
from several patterns of air distribu-
tion. You can select either a primary
mode, as identified by the symbols, or
a blend of two of these modes. The
closer the control is to a particular
mode, the more air distribution you
receive from that mode.
250 UNDERSTANDING YOUR INSTRUMENT PANEL

Panel Mode
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct airflow.
Bi-Level Mode
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.
Floor Mode
Air is directed through the floor outlets with a
small amount through the defrost and side window
demist outlets.
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.
Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use the DEFROST mode
with maximum blower and warm temperature settings
for best windshield and side window defrosting.
NOTE: The air conditioning compressor operates 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.4

Economy Mode
If ECONOMY mode is desired, press the A/C button to
turn off the LED indicator and the A/C compressor.
Rotate the temperature control knob to the desired
temperature.
Air Conditioning Operation
Push this button to engage the Air
Conditioning (A/C). A LED will illu-
minate when the A/C system is
engaged.
MAX A/C
For maximum cooling, when MAX
A/C is selected the A/C is turned on
automatically and the air is recircu-
lated.NOTE:
A/C cannot be deselected when in MAX A/C
position. The LED will blink three times if the A/C
button is pushed.
Automatic Temperature Control (ATC) — If
Equipped
•
The Automatic Temperature Control (ATC) allows
both driver and front passenger seat occupants to
select individual comfort settings.
•When occupants in the vehicle select an Auto mode
operation, Auto blower operation is set by using rotary
knobs on the control unit and a comfort temperature
setting by using the temperature up and down but-
tons.
•The system provides set-and-forget operation for op-
timum comfort and convenience.

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 maximum
blower and temperature settings for best windshield 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
selected to clear the windshield and side glass.
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, Bi-Level 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.

Vacation/Storage
Any time 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 in high. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging and Frosting
Vehicle windows tend to fog on the inside of the glass in
mild, rainy and/or humid weather. Windows may frost
on the inside of the glass in very cold weather. To clearthe 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, can cause
odor, 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.
