2009 DODGE CHALLENGER air conditioning

When you press the VR button, you will hear a beep. The
beep is your signal to give a command.
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 VR button, listen for the beep, and say
your command.
Pressing the VR 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 VR button and
say “Help” or “Main Menu”.

NOTE:If you experience difficulty in playing a particu-
lar disc, it may be damaged (i.e., scratched, reflective
coating removed, a hair, moisture or dew on the disc)
oversized, or have copyright encoding. Try a known
good disc before considering disc player service.
RADIO OPERATION AND CELLULAR PHONES
Under certain conditions, the cellular phone being on in
your vehicle can cause erratic or noisy performance from
your radio. This condition may be lessened or eliminated
by relocating the cellular phone antenna. This condition
is not harmful to the radio. If your radio performance
does not satisfactorily “clear” by the repositioning of the
antenna, it is recommended that the radio volume be
turned down or off during cellular phone operation.
CLIMATE CONTROLS
Manual Air Conditioning and Heating System
The Manual Temperature Control consists of a series of
outer rotary dials and inner pushbuttons.
230 UNDERSTANDING YOUR INSTRUMENT PANEL

Blower Control
Use this control to regulate the
amount of air forced through the ven-
tilation system in any mode. The
blower speed increases as you move
the control to the right from the “O”
(Off) position. There are four blower
speeds.
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 “O” (Off)
position.
Temperature Control
Use this control to regulate the tem-
perature of the air inside the passenger
compartment. The blue area of the
scale indicates cooler temperatures
while 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.

•Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE:The air conditioning compressor operates in
Mix, Defrost, and Floor or a blend of these modes, even
if the Air Conditioning Snowflake button is not pressed.
This dehumidifies the air to help dry the windshield. To
improve fuel economy, use these modes only when
necessary.
•Recirculation Control
Use this button to block the flow of outside air
from coming into the passenger compartment.
A light will illuminate when the system is in
recirculation mode. Use the recirculation mode
to provide maximum A/C performance in hot ambient
conditions, or to block outside odors, dust, etc.NOTE:
•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.
•The use of the recirculation mode in cold or damp
weather may cause windows to fog on the inside,
because of moisture build-up inside the vehicle. Select
the Outside Air position for maximum defogging.
•The A/C will engage automatically to prevent fogging
when the recirculation button is pressed.
•The A/C can be deselected manually without disturb-
ing the mode control selection.
Air Conditioning Control
Use this button to engage the Air Conditioning. A
light will illuminate when the Air Conditioning
System is engaged.

NOTE:The air conditioning compressor will not engage
until the engine has been running for a few seconds.
•MAX A/C
For maximum cooling use the A/C and recirculation
buttons at the same time and set the temperature control
to full cool by rotating the temperature control knob full
counterclockwise.
•Economy Mode
If economy mode is desired, press the A/C button to turn
off the indicator light and the A/C compressor. Then,
move the temperature control to the desired temperature.
Remote Start – If Equipped
During remote start operation, the climate control soft-
ware may override the climate control settings depend-
ing on the outside ambient temperature. The table below
explains the different scenarios that could occur during
remote start operation.
Once the driver enters the vehicle, the control will return
to the customer selected settings. This feature was de-
signed to ensure maximum comfort during extreme
conditions. To enable the feature, customers must park
their vehicles with the blower control set in any of the
four blower speeds.

NOTE:
•The feature can be disable by parking the vehicle with
the blower control set to the “O” (or OFF) position.
•For maximum performance, it is recommended that
the vehicle is parked with the blower control set to the
“High” (full clockwise) position.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
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 protect
against engine overheating. A solution of 50% ethylene
glycol antifreeze coolant and 50% water is recommended.
Refer to “Maintenance Procedures” in Section 7 of this
manual for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime 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 the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.

performance. For example, choose “4” if the desired
speed can be maintained. Choose “3” or “2” if needed
to maintain the desired speed.
Extended driving at high RPM should be avoided to
prevent excess heat generation. A reduction in vehicle
speed may be required to avoid extended driving at
high RPM. Return to a higher gear range or vehicle
speed when road conditions and RPM level allows.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods, put transmission in
NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Recreational towing is allowed ONLY if the driveshaft
is removed.Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
