2004 DODGE GRAND CARAVAN Owners Manual

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 ethylene glycol 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. UNDERSTANDING YOUR INSTRUMENT PANEL 217

Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, use the A/C,
PANEL and blower controls. Direct the panel outlets
toward the side windows. Do not use the Recirculation
mode without A/C for long periods as fogging may
occur.
Interior fogging on the windshield can be quickly re-
moved by using the defrost mode.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow and if they
enter the plenum they could plug the water drains. In
winter months make sure the air intake is clear of ice,
slush and snow. Operating Tips218 UNDERSTANDING YOUR INSTRUMENT PANEL

A/C Air Filter Ð If Equipped
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.
