2006 JEEP LIBERTY Owners Manual

OFF This position turns off the blower motor and outside
air will not pass through any outlets.
Recirculate (Max A/C) Air flows through the outlets located in the
instrument panel. Allows for circulation of
interior air only which will cool the cabin
faster. This setting can be used in very hot
weather to maximize the effect of the air conditioner. This
mode can also be used to temporarily block out outside
odors, smoke, and dust. Slight airflow from the floor
outlets and the defrost outlets, located at the base of the
windshield, may be noticed.
Panel Air flows through the outlets located in the instru-
ment panel. Slight airflow from the defrost outlet,
located at the base of the windshield, may be noticed. Bi-Level
Air flows through the outlets located in the instru-
ment panel, on the floor, and in the rear of the center
console. Slight airflow from the defrost outlet, located at
the base of the windshield, may be noticed.
Floor Air flows through the floor outlets located under
the instrument panel and through the outlets lo-
cated in the rear of the center console. Slight airflow from
the defrost outlet, located at the base of the windshield,
may be noticed. The air conditioning system has been
enabled in Floor mode to provide less humid air, espe-
cially when heat is used. This will help you reduce or
prevent window fogging in high humidity conditions.
This function cannot be disabled. You may still select the
desired amount of heat using the temperature control
dial. The heated air will simply be drier and less prone to
condensing on cold window surfaces.

the base of the windshield, and the side window
demisters outlets.

windshield and through the side window demister
outlets.
Operating Tips
Fast Cool Down
For a fast cool down, turn the blower fan rotary knob to
the extreme clockwise position, turn the mode selector to
the panel position and drive with the windows open for
the first few minutes. Once the hot air has been expelled,
close the windows and turn the mode selector to Max
A/C-Recirculation. When a comfortable condition has been reached, choose a mode position and adjust the
temperature control knob and blower speed as necessary
to maintain comfort. For high humidity conditions it may
be necessary to remain in the Max A/C-Recirculation
mode to maintain comfort.
Window Fogging
In mild but rainy or humid weather, windows will fog on
the inside. To rapidly clear the fog off all the windows,
select the defrost mode, turn the temperature control
knob fully clockwise, and position the blower control to
its highest speed. Once the windshield has been cleared,
adjust the controls for your comfort.
On air conditioned vehicles, the compressor will operate
when in the Mix or Defrost modes and when the outside
temperature is approximately 30°F (-1°C) to provide
additional defrost/defog.

Summer Operation
Air conditioned equipped vehicle’s cooling systems must
be protected with a high quality engine coolant during
summer to provide proper corrosion protection and to
raise the boiling point of the coolant for protection
against overheating. A 50% concentration is recom-
mended.
Winter Operation
When operating the system during the winter months,
make sure the air intake, located directly in front of the
windshield, is free of ice, slush, snow, or other obstruc-
tions.
