engine DODGE CARAVAN 2004 4.G Owner's Manual

Defrost Mode
Air comes from the windshield and side window demist
outlets. Use this setting when necessary to defrost your
windshield and side windows.
NOTE:For improved safety, the compressor is activated
and the recirculation mode is deactivated when Mix orDefrost modes are selected. This is done to assist in
drying the air and it will help in keeping the windows
from fogging.
Manual Air Conditioning Operation
To turn on the air conditioning, set the front
blower control to any position except O (OFF) and
press the A/C button which is located next to the
recirculation button. An indicator light on the A/C
button shows that the air conditioning is on.
Cool dehumidified air comes through the outlets selected
by the Mode Control. To turn off the air conditioning,
press the A/C button a second time. The indicator light
will turn off.
NOTE:
²The compressor will not engage until the engine has
been running for a few seconds.

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 outside air mode when the ignition key
is turned ON. 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.
²Set the mode control to ªPANELº.
²Depress and hold in the ªRear Wipe/Washº button.
²Start the engine, and continue to hold in the ªRear
Wipe/Washº button until the indicator light starts
flashing repeatedly.
²Press the recirculation button until the indicator light
remains lit.
²The selection will be stored when the ignition switch is
turned OFF or if the ªRear Wipe/Washº button is
pressed.
If the recirculation indicator light is lit, the recirculation
mode will not reset when the engine is started. If the
recirculation indicator light is not lit, the recirculation
mode will reset to the outside air mode when the engine
is started. The programmed status can be changed back
and forth by following the above mentioned procedure.

display along with ªHIº or ªLOº. The system will then
automatically regulate the amount of air flow. Next, dial
in the temperature you would like the system to maintain
by pressing the driver's or passenger's temperature con-
trol button. The rear temperature can only be adjusted
from the front when the ªREAR SYSTEMº knob on the
front ATC unit is in the ªAUTOº position. Once the
desired temperature is displayed, the system will achieve
and maintain that comfort level automatically. When the
system is set up for your comfort level, it is not necessary
to change the settings. You will experience the greatest
efficiency by simply allowing the system to function
automatically.
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 ªOverhead Console-Customer Program-
mable 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 front ATC display
until the engine warms up. Also, an estimate of the time
remaining until the ªDELAYº is over will appear peri-
odically in the display. However, the fan will engage
immediately if the defrost mode is selected or by rotating
the blower control to any fixed blower 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.

Bi-Level Mode
Air comes from both the headliner outlets and the
floor outlets.
NOTE:In many temperature positions, the bi-level
mode is designed to provide cooler air out of the head-
liner outlets and warmer air from the floor outlets.
Headliner Mode
Air comes from the outlets in the headliner. Each of
these outlets can be individually adjusted to direct
the flow of air. Moving the air vane knob on the outlets to
one side will shut off the air flow.
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 ethyleneglycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
The air from the heater system will heat faster in cold
weather if you use only low blower speeds for the first 10
minutes of vehicle operation. Use of the air Recirculation
mode during winter months is not recommended be-
cause 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.

Rear Washer Operation Ð Automatic
Temperature Control Only
Press and hold the button as long as spray is
desired. If the switch is depressed while the wipers
are on, the wipers will operate for a few seconds
after the switch is released then resume the previously set
mode of intermittent wiper or continuous wipe. If the
switch is depressed when the wipers are off, the wipers
will operate for two cycles, then turn off.
NOTE:The washers will stop spraying if the switch is
pressed longer than 10 seconds.
Adding Washer Fluid
The fluid reservoir for the windshield washers and the
rear window washer is shared. It is located in the front of
the engine compartment on the passenger side and
should be checked for fluid level at regular intervals. Fillthe reservoir with windshield washer solvent (not radia-
tor antifreeze) and operate the system for a few seconds
to flush out the residual water.
The washer fluid reservoir will hold a full gallon of fluid
when the Low Washer Fluid Light illuminates.

STARTING PROCEDURES
CAUTION!
Long periods of engine idling, especially at high
engine speeds, can cause excessive exhaust tempera-
tures which can damage your vehicle. Do not leave
your vehicle unattended with the engine running.
WARNING!
Do not leave animals or children inside parked
vehicles in hot weather; interior heat build up may
cause serious injury or death.
The gear selector must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
2.4L Engine
Normal Startingof either a cold or a warm engine is
obtained without pumping or depressing the accelerator
pedal. Turn the key to the ªSTARTº position and release
when the engine starts. If the engine has not started
within 3 seconds, slightly depress the accelerator pedal
while continuing to crank. If the engine fails to start
within 15 seconds, turn the key to the ªOFFº position,
wait 10 to 15 seconds, then repeat the normal starting
procedure.
Cold Weather(Below 0É C or 32É F) orHigh Altitude
(Above 4,000 feet at all temperatures). If engine has not
been started within past 3 to 4 hours, slightly depress and
hold the accelerator pedal before attempting to start a
cold engine. Turn the key to the ªSTARTº position. When
the engine starts, release first the key, then the accelerator
pedal. If the engine fails to start within 15 seconds,
discontinue cranking and return the key to the ªOFFº
position. Repeat the starting procedure.
226 STARTING AND OPERATING

Extremely Cold Weather(below229ÉC or220ÉF). To
insure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your dealer) is recommended.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle. If the vehicle has a discharged battery,
booster cables may be used to obtain a start from a
booster battery or the battery in another vehicle. This
type of start can be dangerous if done improperly.
See section 6 of this manual for the proper jump
starting procedures and follow them carefully.
WARNING!
Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
If Engine Fails to Start
If the engine fails to start after you have followed the
ªNORMAL STARTINGº, ªCOLD WEATHERº or ªHIGH
ALTITUDEº procedures, it may be flooded. Push the
accelerator pedal all the way to the floor and hold it there
while cranking the engine. This should clear any excess
fuel in case the engine is flooded.
