2014 Ram ProMaster Compressor

•ECONOMY MODE
If economy mode is desired, press the A/C button to turn
OFF the indicator light and the A/C compressor. Then,
select Panel, Bi-Level or Floor mode and move the
temperature control to the desired temperature.
Mode Control (Air Direction)
Rotate this control to choose from sev-
eral patterns of air distribution. You
can select either a primary mode as
identified by the symbols on the con-
trol, or a blend of two of these modes.
The closer the setting is to a particular
symbol, the more air distribution you
receive from that mode. •
Panel
Air is directed through the outlets in the instru-
ment panel. These outlets can be adjusted to direct
airflow.
NOTE: The center instrument panel outlets can be aimed
so that they are directed toward the rear seat passengers
for maximum airflow to the rear.
• Bi-Level
Air is directed through the panel and floor outlets.
NOTE: For all settings, except full cold or full hot, there
is a difference in temperature between the upper and
lower outlets. The warmer air flows to the floor outlets.
This feature gives improved comfort during sunny but
cool conditions.

•Floor
Air is directed through the floor outlets with a
small amount flowing through the defrost and
side window demist outlets.
• Mix
Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield.
• Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting. NOTE:
The air conditioning compressor operates in Mix,
Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
• Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
• The use of the Recirculation mode in cold or damp
weather will cause windows to fog on the inside,
because of moisture buildup inside the vehicle. Select
the outside air position for maximum defogging.
• Recirculated air is not allowed in Defrost modes. If the
Recirculation button is pressed while in Defrost mode,
the LED indicator will flash several times then go out.
Recirculation will be disabled automatically when
Defrost mode is selected.

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 performance
test. Drive belt tension should also be checked at this
time.
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
Warranty Information Book, located on the DVD,
for further warranty information.

WARNING! (Continued)
•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 technician.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.

VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days, you may want to take these steps to protect your
battery.
•
Disconnect the negative cable from the battery.
• Anytime you store your vehicle, or keep it out of
service (e.g., vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
ensure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
