2008 DODGE CARAVAN air conditioning

A/C AIR FILTER Ð IF EQUIPPED
On vehicles equipped with Automatic Temperature Con-
trol (ATC), the climate control system filters out dust and
pollen from the air. Refer to Section 7 ªAir Conditioningº
for filter replacement instructions.
ELECTRIC REAR WINDOW DEFROSTER Ð IF
EQUIPPED
Press this button (located on your front climate
control) to turn on the rear window defroster and
the optional heated mirrors. A light will show that the
defroster is on. The defroster automatically turns off after
about ten minutes of operation, as long as the ignition
switch is in the ON position.
After the initial time interval has expired, if the rear
window defogger switch is pressed to the on position
again (during the same ignition cycle), the system will
automatically turn off after about five minutes.NOTE:You may turn off the heated mirror feature at
anytime by pressing the rear window defogger switch a
second time.
CAUTION!
To avoid damaging the electrical conductors of the
rear window defroster, do not use scrapers, sharp
instruments, or abrasive window cleaners on the
interior surface of the window.
Labels can be peeled off after soaking with warm
water.
320 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE:
²Check the automatic transmission fluid level before
towing.
²The six-speed automatic transmission is sealed and
requires an authorized dealer service center to check
the transmission fluid.
Towing Tips Ð Electronic Speed Control (If
Equipped)
²
Don't use in hilly terrain or with heavy loads.
²When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
²Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips Ð Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
²City Driving
When stopped for short periods of time, put transmission
gear selector lever in NEUTRAL but do not increase
engine idle speed.
²Highway Driving
Reduce speed.
²Air Conditioning
Turn off temporarily.
²Refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
406 STARTING AND OPERATING

HAZARD WARNING FLASHER
The hazard flasher switch is located in the center of
the instrument panel below the radio.
To engage the Hazard Warning Flashers, depress the
switch on the instrument panel. When the Hazard Warn-
ing Switch is activated, all directional turn signals will
flash on and off to warn oncoming traffic of an emer-
gency. Push the switch a second time to turn off the
flashers.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning Flashers will continue to operate even
though the ignition switch is OFF.NOTE:With extended use, the Hazard Warning Flash-
ers may wear 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.
²On the highways Ð Slow down.
²In city traffic Ð While stopped, shift the transmission
gear selector lever into 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
410 WHAT TO DO IN EMERGENCIES

AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a system
performance check. Drive belt tension should also be
checked at this time.WARNING!
²Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book for
further warranty information.
²The 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
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by an authorized dealer or other an
authorized service facility using recovery and recycling
equipment.
NOTE:Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.
A/C Air Filter Ð If Equipped
Refer to the ªMaintenance Scheduleº in Section 8 of this
manual for A/C Air Filter service intervals.
WARNING!
Do not remove the A/C Air Filter while the blower is
operating or personal injury may result.
The A/C Air Filter is located in the fresh air inlet behind
the glove box. Perform the following procedure to re-
place the filter:
1. Open the glove box and remove all contents.
2. Push in on the sides of the glove box and lower the
door.
3. Pivot the glove box downward.

When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill.
Points To Remember
NOTE:When the vehicle is stopped after a few miles (a
few kilometers) of operation, you may observe vapor
coming from the front of the engine compartment. This is
normally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot coolant to
enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
²Do not overfill the coolant recovery bottle.
²Check coolant freeze point in the radiator and in the
coolant recovery bottle. If antifreeze needs to be
added, contents of coolant recovery bottle must also be
protected against freezing.
²If frequent coolant additions are required, or if the
level in the coolant recovery bottle does not drop when
the engine cools, the cooling system should be pres-
sure tested for leaks.
²Maintain coolant concentration at 50% HOAT engine
coolant (minimum) and distilled water for proper
corrosion protection of your engine which contains
aluminum components.
²Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
