2007 DODGE MAGNUM air condition

•Panel
Air flows through the outlets located in the
instrument panel. Air flows through the regis-
ters in the back of the center console to the rear seat
passengers. These registers can be closed to block
airflow.
•
Recirculation Control
The mode control knob also controls the
recirculation feature. You can choose Bi-
Level Recirculation air outlets, Panel Re-
circulation air outlets, or a mix or both
while in this mode. Normally, air enters from out-
side the vehicle. However, when in Recirculation
mode air inside the vehicle is re-used. Use this
mode to cool the inside of the vehicle rapidly. The
Recirculation mode can also be used to temporarily
block out outside odors, smoke, and dust.
Air Conditioning Control
Press this button to turn on and turn off the air
conditioning. When the air conditioning is turned
on, cool dehumidified air will flow through the
outlets selected with the mode control. Press this buttona second time to turn off the air conditioning. An LED in
the button will illuminate when compressor operation is
selected.
Automatic Temperature Control — If Equipped
Automatic Operation
The Infrared Dual-Zone Climate Control System auto-
matically maintains the climate in the cabin of the vehicle
at the comfort levels desired by the driver and passenger.
To accomplish this, the system gathers information from
Automatic Temperature Controls

the controls on the climate control, from a dual sun-
sensor located in the top of the instrument panel, from an
infrared sensor located in the face of the climate control,
and from various sensors located throughout the vehicle.
The controls on the climate control provide the system
with operator input. The dual sun-sensor monitors sun
load coming through the windshield. The infrared sensor
independently measures the surface temperature of the
driver and passenger. Other sensors take account of
vehicle-speed, A/C pressure, outside temperature, and
engine cooling temperature. Using all of these inputs, the
system automatically adjusts airflow temperature, air-
flow distribution, airflow volume, and the amount of
outside air recirculation. This maintains a comfortable
temperature even under changing conditions.
Operation of the system is quite simple. Begin by turning
the Mode Control knob (on the right) to AUTO, and place
the Blower Control knob (on the left) to either LO AUTO
or HI AUTO. The LO AUTO position should be used for
front seat occupants only. The HI AUTO position should
be used when more airflow is desired, or when rear seat
occupants are present. Then, dial in the temperature youwould like the system to maintain by rotating the driver
or passenger Temperature Control knob. Once the com-
fort level is selected, the system will maintain that level
automatically using the heating system. Should the de-
sired comfort level require air conditioning, the system
will automatically make the adjustment.
You will experience the greatest efficiency by simply
allowing the system to function automatically. Selecting
the OFF position on the fan control stops the system
completely and closes the outside air intake.
72°F (22°C) is the recommended setting for maximum
comfort for the average person; however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic operation.
Air conditioning in this system is automatic.
Pressing the Air Conditioning Control button
while in AUTO mode will cause the LED in the
control button to flash three times and then turn off.
This indicates that the system is in AUTO mode and
requesting the air conditioning is not necessary.

The system will automatically control recir-
culation. However, pressing the Recircula-
tion Control button will temporarily put the
system in recirculation mode (ten minutes).
This can be used when outside conditions such as
smoke, odors, dust, or high humidity are present.
Activating recirculation will cause the LED in the
control button to illuminate. After ten minutes, the
system will return to normal AUTO mode function
and the LED will turn off.
NOTE:
•
The surface of the climate control panel and the top
center of the instrument panel should be kept free of
debris due to the location of the climate control
sensors. Mud on the windshield may also cause poor
operation of this system.
•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the Recirculation button to return to outside air.Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper
visibility. For this reason, the system will not allow
Recirculation to be selected while in defrost or
defrost/floor mode. Attempting to use the recircula-
tion while in these modes will cause the LED in the
control button to blink and then turn off.
Manual Operation
This system offers a full complement of manual override
features, which consist of Blower Preferred Automatic,
Mode Preferred Automatic, or Blower and Mode Pre-
ferred Automatic. This means the operator can override
the blower, the mode, or both. There is a manual blower
range for times when the AUTO setting is not desired.
The blower can be set to any fixed blower speed by
rotating the Blower Control knob (on the left).
NOTE:Please read the Automatic Temperature Control

This button can be used to block out smoke,
odors, dust, high humidity, or if rapid cooling
is desired. The recirculation mode should only
be used temporarily. An LED in the button
illuminates when the recirculation mode is active. You
may use this feature separately.
NOTE:Extended use of recirculation may cause the
windows to fog. If the interior of the windows begins to
fog, press the Recirculation button to return to outside
air. Some temp/humidity conditions will cause captured
interior air to condense on windows and hamper visibil-
ity. For this reason, the system will not allow Recircula-
tion to be selected while in defrost or defrost/floor mode.
Attempting to use the recirculation while in these modes
will cause the LED in the control button to blink and then
turn off.
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 50% solution of ethylene
glycol antifreeze coolant in 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 condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate

WARNING!
•The Anti-Lock Brake System contains sophisticated
electronic equipment that may be susceptible to inter-
ference caused by improperly installed or high output
radio transmitting equipment. This interference can
cause possible loss of anti-lock braking capability. In-
stallation of such equipment should be performed by
qualified professionals.
•Pumping of the Anti-Lock Brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly on
your brake pedal when you need to slow down or stop.
•Anti-lock system (ABS) cannot prevent the natural laws
of physics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires or the
traction afforded.
•The ABS cannot prevent accidents, including those
resulting from excessive speed in turns, following an-
other vehicle too closely, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
•The capabilities of an ABS equipped vehicle must never
be exploited in a reckless or dangerous manner, which
could jeopardize the user’s safety or the safety of others.
All vehicle wheels and tires must be the same size and
type and tires must be properly inflated to produce
accurate signals for the computer.
Anti-Lock Brake Light
The ABS light monitors the Anti-Lock Brake Sys-
tem. The light will come on when the ignition
switch is turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
Ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning Light and the ABS Light
remain on, the Anti-Lock brakes (ABS) and Electronic

CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure.” Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least 3 hours, or driven less than 1 mile
(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall.
Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12° F (7° C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the winter.Example: If garage temperature = 68° F (20° C) and the
outside temperature = 32° F (0° C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12° F (7° C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to original equipment or an authorized tire
dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
246 STARTING AND OPERATING

Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare.
Do not install more than one compact spare tire/wheel
on the vehicle at any given time.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with the
compact spare installed. Damage to the vehicle may
result.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary emergency use
on your vehicle. This tire is identified by a limited use
spare tire warning label located on the limited use spare
tire and wheel assembly. This tire may look like the
original equipped tire on the front or rear axle of your
vehicle, but it is not. Installation of this limited use sparetire affects vehicle handling. Since it is not the same tire,
replace (or repair) the original tire and reinstall on the
vehicle at the first opportunity.
WARNING!
The limited use spare tires are for emergency use
only. Installation of this limited use spare tire affects
vehicle handling. With this tire, do not drive more
than 60 mph (100 km/h). Keep inflated to the cold
tire inflation pressure listed on either your tire
placard or limited use spare tire and wheel assembly.
Replace (or repair) the original tire at the first
opportunity and reinstall it on your vehicle. Failure
to do so could result in loss of vehicle control.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 35 mph (55 km/h).
Refer to the paragraph on “Freeing A Stuck Vehicle” in
Section 6 of this manual.
