2009 JEEP LIBERTY air conditioning

•Air Conditioner ControlPress this button to turn on the air conditioning
during manual operation only. When the air con-
ditioning is turned on, cool dehumidified air will
flow through the outlets selected with the Mode control
dial. Press this button a second time to turn off the air
conditioning. An LED in the button illuminates when
manual compressor operation is selected.
•Recirculation Control The system will automatically control recircu-
lation. However, pressing the Recirculation
Control button will temporarily put the system
in recirculation mode (ten minutes). This can
be used when outside conditions such as smoke, odors,
dust, or high humidity are present. Activating recircula-
tion will cause the LED in the CONTROL button to
illuminate. After ten minutes, the system will return to
normal AUTO mode function and the LED will turn off. NOTE:
•When the ignition switch is turned to the LOCK
position, the recirculation 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 floor, defrost, or defrost/
floor mode in order to improve window clearing.
Recirculation will be disabled automatically if these
modes are selected.
•Extended use of recirculation may cause the windows
to fog. If the interior of the windows begins to fog,
press the RECIRCULATION button to return to out-
side air. Some temp/humidity conditions will cause
captured interior air to condense on windows and
hamper visibility. For this reason, the system will not
allow Recirculation to be selected while in floor, de-
frost, or defrost/floor mode. Attempting to use the
Recirculation while in these modes will cause the LED
in the CONTROL button to blink and then turn off.

•Most of the time, when in Automatic Operation, you
can temporarily put the system into Recirculation
mode by pressing the RECIRCULATION button.
However, under certain conditions, while in Auto-
matic Mode, the system is blowing air out the defrost
vents. When these conditions are present, and the
RECIRCULATION button is pressed, the indicator will
flash and then turn off. This tells you that you are
unable to go into recirculation mode at this time. If you
would like the system to go into Recirculation mode,
you must first move the Mode Knob to Panel, Panel/
Floor and then press the RECIRCULATION button.
This feature reduces the possibility of window
fogging.
Operating Tips
NOTE:Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
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 “Maintenance Procedures” in Section 7 of this manual
for proper coolant selection.
Winter Operation
Use of the air Recirculation mode during winter months
is not recommended because 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
conditioning system at idle for about five minutes in the
fresh air and high blower settings. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the system is started again.

Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, put transmission
in NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
Towing – Two-Wheel Drive Models
Recreational towing is allowed ONLY if the driveshaft
is removed. Towing with the rear wheels on the ground
while the driveshaft is connected can result in severe
transmission damage.
Towing — Four-Wheel Drive Models
The transfer case must be shifted into NEUTRAL for
recreational towing. The NEUTRAL selection button is
located at the top of the 4WD Control Switch. Shifts into
and out of transfer case NEUTRAL can take place with
the selector switch in any mode position.
CAUTION!
•The transmission must be in PARK position for
recreational towing. Failure to follow these proce-
dures can cause severe transmission and/or trans-
fer case damage.
•Internal damage to the transmission or transfer
case will occur if a front or rear wheel lift is used
when recreational towing.

CAUTION! (Continued)
•If a “fast charger” is used while the battery is in
the vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do
not use a “fast charger” to provide starting voltage
as battery damage can result.
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
Section 3 of the Warranty Information Book for
additional 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 technician.
418 MAINTAINING YOUR VEHICLE

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
service facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, and Refrigerants.
A/C Air Filter — If Equipped
Refer to the “Maintenance Schedule” in Section 8 for the
proper maintenance intervals.
WARNING!
Do not remove the A/C Air Filter while the blower is
operating or personal injury may result.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium based grease such as
MOPAR Spray White Lube to assure quiet, easy opera-
tion and to protect against rust and wear. Prior to the
application of any lubricant, the parts concerned should
be wiped clean to remove dust and grit; after lubricating
excess oil and grease should be removed. Particular
attention should also be given to hood latching compo-
nents to ensure proper function. When performing other
underhood services, the hood latch, release mechanism
and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant such as MOPAR
Lock Cylinder Lubricant directly into the lock cylinder.

the engine operating temperature is satisfactory, the
coolant bottle need only be checked once a month.
When additional engine coolant (antifreeze) 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/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is nor-
mally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being vapor-
ized when the thermostat opens, allowing hot engine
coolant (antifreeze) 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.
•Do not overfill the coolant bottle.
•Check coolant freeze point in the radiator and in the
coolant recovery bottle. If engine coolant (antifreeze)
needs to be added, contents of coolant recovery bottle
must also be protected against freezing.
•If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
•Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (minimum)
and distilled water for proper corrosion protection of
your engine, which contains aluminum components.
•Make sure that the radiator and coolant recovery
bottle hoses are not kinked or obstructed.
•Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
