JEEP LIBERTY 2010 KK / 2.G Owners Manual

•Air Conditioner ControlPress this button to turn on the air
conditioning during manual operation
only. When the air conditioning is
turned on, cool dehumidified air will
flow through the outlets selected with
the Mode control dial. Press this but-
ton 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 illumi-
nate. 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 outside 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, defrost, or
defrost/floor mode. Attempting to use the recircula-
tion 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 Automatic 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 thesystem 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 solution of 50% ethylene
glycol antifreeze coolant and 50% 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.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clearwindshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:
Recirculate without A/C should not be used for
long periods as fogging may occur.
Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
FLOOR, MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view the
outside mirrors.
292 UNDERSTANDING YOUR INSTRUMENT PANEL

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.
A/C Air Filter — If Equipped
The A/C Filter prevents most dust and pollen from
entering the cabin. The filter acts on air coming from
outside the vehicle and recirculated air within the pas-
senger compartment. Refer to “Maintenance Procedures”
in Section 7 of this manual for A/C Air Filter service
information or see your authorized dealer for service.
Refer to the “Maintenance Schedules” in Section 8 of this
manual for filter service intervals.

WARNING!
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up may
cause serious injury or death.
Start the engine with the shift lever in the NEUTRAL or
PARK position. Apply the brake before shifting to any
driving range.
Normal Starting
NOTE: Normal starting of either a cold or a warm
engine is obtained without pumping or pressing the
accelerator pedal. Turn the ignition switch to the START position and
release when the engine starts. If the engine fails to start
within 10 seconds, turn the ignition switch to the LOCK
position, wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.

Turn the ignition switch to START position and release it
as soon as the starter engages. The starter motor will
continue to run, but will automatically disengage itself
when the engine is running. If the engine fails to start, the
starter will disengage automatically in 10 seconds. If this
occurs, turn the ignition switch to the LOCK position,
wait 10 to 15 seconds, then repeat the “Normal Starting”
procedure.
