air condition DODGE GRAND CARAVAN 2006 User Guide

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 or Defrost 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:
• The compressor will not engage until the engine has
been running for a few seconds.Defrost Outlets UNDERSTANDING YOUR INSTRUMENT PANEL 279

• If your air conditioning performance seems lower than
expected, check the A/C air filter, if so equipped, and
the front of the A/C condenser for an accumulation of
dirt or insects. The A/C condenser is located in front
of the radiator. The A/C air filter is located under the
instrument panel on the passenger side.
• Fabric type fascia protectors tend to block the amount
of air to the condenser and may reduce air condition-
ing performance.
Economy Mode
If economy mode is desired, press the A/C button to turn
off the indicator light, and the A/C compressor. Move the
temperature control lever to the desired temperature.
Recirculation Control
Press the recirculation button to recirculate the
air inside the vehicle. This is located next to the
A/C button. An indicator light on the button
shows that air is being recirculated. Use the recirculation mode to rapidly cool the inside of the
vehicle. The recirculation mode can also be used to
temporarily block out outside odors, smoke, and dust.
NOTE:
• When the ignition switch is turned OFF, the recircula-
tion feature will be cancelled.
• 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.
• If the recirculation button is pressed while in the Mix
or Defrost mode, the indicator light in the recirculation
button will flash 3 times indicating that recirculation is
not allowed.280 UNDERSTANDING YOUR INSTRUMENT PANEL

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:
• Turn the ignition switch to the OFF position.
• Set the mode control to “ PANEL ” . • Depress and hold in the “ Rear Wipe/Wash ” button.
• Start the engine, and continue to hold in the “ Rear
Wipe/Wash ” button until the indicator light starts
flashing repeatedly.
• Press the recirculation button until the indicator light
remains lit.
• The selection will be stored when the ignition switch is
turned OFF or if the “ Rear Wipe/Wash ” 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. UNDERSTANDING YOUR INSTRUMENT PANEL 281

driver and passenger. Based on the sensor input, the
system automatically adjusts the air temperature, the air
flow volume, and amount of outside air recirculation.
This maintains a comfortable temperature even under
changing conditions.
Operation of the system is quite simple. Begin by press-
ing the auto rocker switch to the “ HI ” or “ LO ” position,
the word “ AUTO ” will illuminate in the front ATC
display along with “ HI ” or “ LO ” . 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 “ REAR SYSTEM ” knob on the
front ATC unit is in the “ AUTO ” 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:
• It 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.Three-Zone Automatic Temperature Control UNDERSTANDING YOUR INSTRUMENT PANEL 285

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: While operating in either  Auto HI  or  Auto
LO  , the system will not automatically sense the presence
of fog, mist, or ice on the windshield.  Defrost  mode
must be manually selected to clear the windshield and
side glass.
The  snowflake  or  a/c  button allows the opera-
tor to manually activate or deactivate the air
conditioning system. When the snowflake symbol
in the ATC display is on, cool, dehumidified air flows
through the air outlets. If economy mode is desired, press
the snowflake button to turn off the snowflake icon in the
ATC display and deactivate the air conditioning system.
Note: While operating in  auto hi  or  auto lo  , the air
conditioning system is always activated. If fog, or mist
appears on the windshield or side glass, select  defrost 
mode and increase blower speed.Defrost Outlets290 UNDERSTANDING YOUR INSTRUMENT PANEL

Rear Mode Control
The Rear Mode Control, located in
the headliner near the center of
the vehicle can be used to select
between Auto, Headliner, Bi-
Level and Floor modes.
Auto Mode
The rear system automatically maintains the correct
mode and comfort level desired by the rear seat occu-
pants.
Floor Mode
Air comes from the floor outlets. 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 ethylene294 UNDERSTANDING YOUR INSTRUMENT PANEL

Operating Tips A/C Air Filter — 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 MAINTAINING YOUR VEHICLE,
“ Air Conditioner Maintenance ” for filter replacement
instructions.
REAR WINDOW FEATURES
Intermittent Rear Wiper Operation — Manual
Temperature Control Only
The controls are located on the Manual Tempera-
ture Control head above the front blower control.
When the button is pressed and released and the
Ignition Switch in ON, the rear wiper will operate at a
fixed interval of about 8 seconds. As vehicle speed
increases, the time delay will shorten. The LED indicator
will light when the wiper is ON. Pressing and releasing

by increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Lamp.
Anti-Lock Brake System — If Equipped
The Anti-Lock Brake System provides increased vehicle
stability and brake performance under most braking
conditions. The system automatically “ pumps ” the
brakes during severe braking conditions to prevent
wheel lock-up.
WARNING!Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to an accident.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop. The ABS light monitors the Anti-Lock Brake
System. 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. STARTING AND OPERATING 315

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
“ cold tire inflation pressure ” . 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 1 mile
(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
12 ° F(7 ° C) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the winter.
Example: If garage temperature = 68 ° F (20 ° C) and the
outside temperature = 32 ° F(0 ° C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12 ° F(7 ° C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures for High Speed Operation
The manufacturer advocates driving at safe speeds
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle330 STARTING AND OPERATING
