2006 DODGE GRAND CARAVAN air filter

• 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

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,

Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, use only those oils that are American
Petroleum Institute (API) Certified and have the recom-
mended SAE viscosity grade. Follow the maintenance
schedule that describes your driving type.
Materials Added to Engine Oil
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it ’ s performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your dealer, service station, or governmental agency for advice on how and where used
oil and oil filters can be safely discarded in your area.
Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
All the manufacturers engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. Mopar Engine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts — Check Condition and Tension
At the mileage indicated in the maintenance schedule, all
belts should be checked for condition and proper tension.
Improper belt tension can cause belt slippage and failure. MAINTAINING YOUR VEHICLE 405
7

Belts should be inspected for evidence of cuts, cracks, or
glazing, and replaced if there is indication of damage
which could result in belt failure. If adjustment is re-
quired, the belts must be adjusted according to the
specifications and procedures described in the Service
Manual. Low generator belt tension can cause battery
failure. A special tool is required to properly measure
tension and to restore belt tension to factory specifica-
tions.
Also check belt routing to make sure there is no interfer-
ence between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark plug, malfunctioning spark plugs can damage the cata-
lytic converter. For proper type of replacement spark
plugs, refer to the “ Vehicle Emission Control Informa-
tion ” label in the engine compartment.
Engine 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 ” .406 MAINTAINING YOUR VEHICLE

WARNING!• Use 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.
• 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
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
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 — If Equipped
The A/C Air Filter — if so equipped, is found behind the
filter access door located under the instrument panel on
the passenger side. To replace the filter slide the lock
toward the rear of the vehicle (unlock position). Remove
the access door and pull the filter downward. When
installing a new filter, ensure its proper orientation. Align MAINTAINING YOUR VEHICLE 411

the black arrow on the bottom of the filter frame with the
direction of airflow (away from the blower motor and
towards the center of the car).
Refer to the “ Maintenance Schedules ” section of this
manual for the recommended air conditioning filter
replacement intervals.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.  WARNING!Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front Suspension Ball Joints
The front suspension ball joints are permanently sealed.
No regular maintenance is required for these compo-
nents.412 MAINTAINING YOUR VEHICLE
