2004 CHRYSLER PACIFICA air condition

regulates the heating and air conditioning system includ-
ing blower speed, outlet air temperature, and airflow
distribution through the various outlets within the in-
strument panel. Using the9TEMP9buttons, adjust the
temperature you would like the system to maintain.
When the system is set to your comfort level, it is not
necessary to change the settings. You will experience the
greatest efficiency by allowing the system to function
automatically. The system will operate fully automati-
cally in either9AUTO HI9or9AUTO LO9. The9AUTO
LO9setting will limit the maximum fan speed and should
be used when more quiet operation is desired. Use the
9AUTO HI9setting when the quickest cool-down or
warm-up performance is desired.
NOTE:
²It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode and fan speed to provide
comfort as quickly as possible.
²The temperature can be displayed in U.S. or Metric by
selecting the US/M customer programmable feature.
Refer to the ªElectronic Vehicle Information Center-
Customer Programmable Featuresº in Section 3 of this
manual.
To provide you with maximum comfort in the automatic
mode, during cold start-ups the blower fan will remain
off and ªDELAYº will appear in the display until the
engine warms up. An estimate of the time remaining
until the ªDELAYº is complete will appear periodically
in the display. However, the fan will engage immediately
if the defrost mode is selected or by pushing the blower
switch and manually adjusting the fan speed.
This feature may be disabled using the following proce-
dure:
²Press and hold the Heated Rear Window and Auto LO
buttons for 5 seconds.

NOTE:While operating in9AUTO HI9or9AUTO LO9,
the system will not automatically sense the presence fog,
mist, or ice on the windshield. The defrost button must be
pressed to clear the windshield and side glass.
Depress the ªA/Cº button to turn on and off the
air conditioning during manual operation only.
Cool dehumidified air comes through the outlets
selected by the Mode Control. To turn off the air condi-
tioning, press the A/C button a second time. The A/C
symbol in the display will turn off.
NOTE:If a fog or mist appears on the windshield or
side glass, press the ªA/Cº button to engage the com-
pressor or press the defrost button. If a fog or mist on the
windshield or side glass starts to impair visibility, press
the front blower button and increase the fan speed to
maximum.Recirculation Control
When the outside air contains smoke, odors,
high humidity, or if rapid cooling is desired
you may wish to recirculate interior air by
pressing the recirculation button. The recircu-
lation mode should only be used temporarily. The recir-
culate symbol will illuminate in the display when this
button is selected. Push the button a second time to 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 the Mix and Defrost modes to
improve window clearing operation. Recirculation will
be disabled automatically if these modes are selected.

A/C Recirculation Programming
The recirculation control is programmed to cancel the
recirculation mode when the ignition key is turned OFF
and will reset to the outside air mode when the ignition
key is turned ªONº. The frequent use of outside air will
help keep odors from building up within the air
conditioner-heater housing. It is recommended that the
recirculation mode be used as little as possible, especially
in humid climates.
For hot and dry climates, or people who are allergic to
pollen and find frequent use of the recirculation mode
necessary, the recirculation mode can be programmed to
not automatically reset to the outside mode by using the
following procedures:
²Turn the ignition switch to the OFF position.
²Press and hold the recirculation button.
²While holding the recirculation button, turn the igni-
tion switch to the ªRUNº position.
²Continue holding the recirculation button for 4 sec-
onds, then release.
The recirculation control is now programmed so that the
recirculation mode willnotreset to the outside air mode
when the engine is restarted. The recirculation program-
ming can be changed back by repeating this procedure.

Rear Fan Operation
To operate the rear fan, press the9REAR9button. The first
time this button is pressed the9REAR AUTO9display
will illuminate indicating that the rear fan speed is
automatically controlled. To manually control the rear
fan speed, press the9REAR9button again and only
9REAR9will illuminate in the display. This allows the rear
seat occupants to control the rear fan speed using the
switch located in the center console between the second
row seats. By pressing the9REAR9button a third time,
the rear fan will shut off.
When the ATC display reads9REAR AUTO9or when the
rear fan is off, the switch located in the center console
between the second row seats is not functional. When the
ATC display reads9REAR9, only the rear seat occupants
can control the rear fan speed from the rear switch. When
in the ªREARº mode, the rear occupants can set the rearswitch to any fan speed including9OFF9,or9AUTO9.
While in the9AUTO9position, the rear fan speed will be
automatically controlled.
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 section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
To insure 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 section 7, Maintenance
Procedures, of this manual for proper coolant selection.

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
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, use the A/C
button to reduce the humidity inside the vehicle.
Fogging on the inside of the windshield can be quickly
removed by pressing the defrost button and increasing
the blower speed.Do not use the Recirculation mode without the A/C
button for long periods as fogging may occur.
Outside Air Intake
Before driving, always make sure the air intake located
directly in front of the windshield is free of obstructions
such as leaves, ice, or snow, which could reduce airflow
and/or plug the water drain tube inside the plenum.
A/C Air Filter
The climate control system filters out dust, pollen and
some odors from the air. Strong odors can not be totally
filtered out. Refer to section 7 ªAir Conditioningº for
filter replacement instructions.

WARNING!
²Anti-lock system (ABS) cannot prevent the natu-
ral laws of physics from acting on the vehicle, nor
can it increase braking or steering efficiency be-
yond that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
²The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
²The 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.
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
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.

The pressure should be checked and adjusted as well as
inspecting for signs of tire wear or visible damage at least
once a month. Use a good quality pocket-type gauge to
check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are underinflated.
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
ªcold tire inflation pressureº. 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 1mile(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire side wall.
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
12É F (7É C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage especially in
the winter.
Example: If garage temperature = 68É F (20É C) and the
outside temperature = 32É F (0É C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12É F (7É C) for this
outside temperature condition.
224 STARTING AND OPERATING

CAUTION!
If the Malfunction Indicator light is flash-
ing, immediate service is required. Refer to
the paragraph on the Onboard Diagnostics
System in section 7 of this manual.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and would result in additional cost.
Therefore you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
damage the emission control system, and could result
in loss of warranty coverage.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out-of-tune or
malfunctioning and may require immediate service.
Contact your dealer for service assistance.
