2004 DODGE INTREPID air condition

NOTE:The Recirc button light will blink if you try to
use it in the Mix or Defrost modes.
Air Direction Buttons (Mode)
These buttons allow you to select from five air distribu-
tion patterns. These buttons should be used only when
you can not achieve comfort or visibility in Auto opera-
tion. A symbol in the display window will show which
mode is operating.
Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
air flow. This mode is not recommended when heat is
required.
Floor
Air is directed through the floor outlets with a
lesser amount through the Defrost and side
window demist outlets. This mode is recommended
when heat is desired.
Mix
Air is directed through the floor, defrost, and
side window demist outlets. Use this setting incold or snowy conditions that require extra heat at the
windshield. This setting is good for maintaining com-
fort while reducing moisture on the windshield. The
compressor is on in this mode.
Bi-Level
Air is directed through both the panel and floor
outlets. This mode is not recommended when
heat is required in very cold temperatures.
NOTE:There is a varying difference in temperature
between the upper and lower outlets for added comfort.
The warmer air goes to the floor outlets. This feature
provides improved comfort during sunny but cool con-
ditions.
Windshield Defrost
Air is directed through the defrost outlets and
side window demist outlets. A small amount of
air also is directed through the floor outlets. Use this
mode with maximum fan and comfort level settings
for best windshield and side window defrosting. The
defrost symbol will glow in amber to show that the
defroster is on.

NOTE:The air conditioning compressor is on in this
mode. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, leave in the defrost
mode only when necessary.
Rear Window Defroster
Press the button once to turn on the Rear Window
Defroster and a second time to turn it off. An
indicator light to the right of the control shows that the
defroster is on.
NOTE:The defroster turns off automatically after 15
minutes of operation. Each later activation will allow 7
1/2 minutes of operation.
CAUTION!
To avoid damaging the electrical conductors, do not
use scrapers, sharp instruments, or abrasive window
cleaners on the interior surface of the rear window.
Labels can be peeled off by soaking with warm
water.
Window Fogging
In mild but rainy or humid weather, your windows may
fog up on the inside. You can remove this fog by pressing
the Defrost button. The Mix mode can be used to
maintain a clear windshield and provide sufficient heat-
ing. If side window fogging becomes a problem, increase
blower speed. The compressor will remain on during
these conditions.
Hot Weather Automatic Recirculation
The system will automatically recirculate the air inside
the vehicle when the interior is very warm. This will
provide maximum cooling. The system will also occa-
sionally return to REC on hot, humid days to maintain
occupant comfort.
NOTE:See Operating Tips chart (for both Manual A/C
and ATC systems) at the end of this section for suggested
control settings in different weather conditions.

After Starting
The idle speed will automatically decrease as the engine
warms up. At cooler ambient temperatures, the idle
speed for the 2.7L engine may increase during extended
idles for improved heater performance.
ENGINE BLOCK HEATER — Optional U.S. and
Standard Canada
These heaters use a common power cord which is stored
under the hood, behind the Air Cleaner housing. Plug the
cord into any 110 volt AC outlet and both heaters will be
energized. Use the heaters when temperatures below 0°F
(-18°C) are expected to last for several days.
AUTOMATIC TRANSAXLE
Brake/Transmission Interlock
This interlock system prevents you from moving the gear
selector out of the Park position unless the brake pedal is
pressed. This system is active only while the key is in the
RUN position.
CAUTION!
Damage to the transaxle may occur if the following
precautions are not observed:
•Shift into PARK only after the vehicle has come to a
complete stop.
•Shift into or out of REVERSE only after the vehicle has
come to a complete stop and the engine is at idle
speed.
•Do not shift from REVERSE, PARK or NEUTRAL into
any forward gear when the engine is above idle speed.
•Before shifting into any gear, make sure your foot is
firmly on the brake pedal.
The electronically controlled transaxle provides a precise
shift schedule. The transaxle electronics are self-
calibrating. Therefore, the first few shifts on a new
vehicle may be somewhat abrupt. This is a normal
condition, and precision shifts will develop within a few
shift cycles.

HAZARD WARNING FLASHER
The flasher switch is on the steering column, just
behind the steering wheel. Push in the flasher
switch and all front and rear directional signals
will flash. Press the flasher switch a second time to turn
the flashers off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher may run down
your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put transaxle in
neutral, but do not increase engine idle speed.
NOTE:There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
152 WHAT TO DO IN EMERGENCIES

the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads “H”, pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H”, turn the engine off immediately, and call for
service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.

Engine Timing Belt
Replace the engine timing belt at the intervals described
in the appropriate maintenance schedule.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.
Fuel Filter
A plugged fuel filter can cause hard starting or limit the
speed at which a vehicle can be driven. Should an
excessive amount of dirt accumulate in the fuel tank,
frequent replacement of the fuel filter which is mounted
in the fuel tank may be necessary. See your dealer for
service.
Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on Schedule “A”. If, however, you
drive the vehicle frequently under dusty or severe con-
ditions, the filter element should be inspected periodi-
cally and replaced if necessary at the intervals shown on
Schedule “B”.
WARNING!
The air cleaner can provide a measure of protection
in the case of engine backfire. Do not remove the air
cleaner unless such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with
the air cleaner removed. Failure to do so can result in
serious personal injury.
180 MAINTAINING YOUR VEHICLE

CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and identified on the battery case.
Cable clamps should be tight on the terminal posts
and free of corrosion. Apply grease to posts and
clamps after tightening. If a “fast charger” is used
while the battery is in the vehicle, disconnect both
vehicle battery cables before connecting the charger
to battery. Do not use a “fast charger” to provide
starting voltage as battery damage can result.
Air Conditioner
Check the air conditioning system at the start of the
warm weather season.
NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects. Clean with
a gentle water spray from behind the radiator andthrough the condenser as required. Fabric front fascia
protectors may reduce air flow to the condenser, reducing
air conditioning performance.
WARNING!
The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal injury
or damage to the system, adding refrigerant or any
repair requiring lines to be disconnected should be
done by an experienced repairman.
Refrigerant Recovery and Recycling
The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere. The manufacturer recommends
that air conditioning service be done by facilities using
refrigerant recyling and recovery equipment that meets
SAE standard J1991.
