2007 JEEP PATRIOT Owners Manual

The air conditioning system of your vehicle contains
R-134a, a refrigerant that does not deplete the ozone layer
in the upper atmosphere.
The controls are as follows:
Fan Control
Use this control to regulate
the amount of air forced
through the system in any
mode you select. The fan
speed increases as you move
the control to the right from
the OFF position.
Mode Control (Air Direction)
The mode control allows you
to choose from several pat-
terns of air distribution. You
can select either a primary
mode, as identified by the
symbols, or a blend of two of
these modes. The closer the
control is to a particular
mode, the more air distribu-
tion you receive from that
mode.
Panel
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct air
flow.
Bi-Level
Air is directed through the panel and floor outlets.

NOTE:There is a difference in temperature between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Floor
Air is directed through the floor outlets and side
window demist outlets with a small amount
through the defrost outlet.
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 at
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 fan and temperature settings for best windshield
and side window defrosting.
NOTE:The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes even if
the Air Conditioning Snowflake button is not pressed.
This dehumidifies the air to help dry the windshield. To
improve fuel economy, use these modes only when
necessary.
Air Outlets
The airflow from each of the instrument panel outlets can
be adjusted for direction and turned on or off to control
air flow.

NOTE:For maximum airflow to the rear seat passen-
gers, the center instrument panel outlets can be aimed, so
that the left center outlet is directed toward the right rear
passenger and the right center outlet is directed toward
the left rear passenger.
Temperature Control
Use this control to regulate
the temperature of the air in-
side the passenger compart-
ment. The blue area of the
scale indicates cooler tem-
peratures while the red area
indicates warmer tempera-
tures.NOTE:If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser: located in front of the radiator, for an accumula-
tion of dirt or insects. Clean with a gentle water spray
from behind the radiator and through the condenser.
Fabric front fascia protectors may reduce air flow to the
condenser, reducing air conditioning performance.
Air Conditioning
MAX A/C
For maximum cooling use the
A/C and recirculate buttons
at the same time.

NOTE:See ªCirculation Controlº later in this section,
for proper or extended use of this position.
Air Conditioning (Normal)
Use this button to engage the
Air Conditioning. A lamp will
illuminate when the Air Con-
ditioning System is engaged.
Once the air conditioning is
engaged, use a combination
of the mode control, fan
speed control, and tempera-
ture control to achieve your
desired interior temperature.
NOTE:The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.
Circulation Control
Use this button to choose be-
tween outside air intake or
recirculation of the air inside
the vehicle. A lamp will illu-
minate when you are in recir-
culate mode. Only use the re-
circulate mode to temporarily
block out any outside odors,
smoke, or dust and to cool the
interior rapidly upon initial
start up in very hot or humid weather.

NOTE:Continuous use of the recirculate mode may
make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold or damp weather, the use of the Recirculate
position will cause windows to fog on the inside because
of moisture build up inside the vehicle. For maximum
defogging, select the Outside Air position.
NOTE:Recirculation Mode will not operate in floor, mix
or defrost modes.
Air Filtration System ± If Equipped
An air filter is included in the optional Security Group.
Filter media includes a particle filtration layer and acharcoal layer. The filter will reduce, but not eliminate,
diesel and agricultural smells. The filter acts only on air
coming from outside the vehicle; it does not filter air
inside the passenger compartment. See the maintenance
schedule for the filter change interval. The air filter
change interval coincides with engine oil and filter
change intervals. As with oil changes, the interval is
shorter for heavy duty service or dusty conditions. See
your authorized dealer for service.

Window Fogging
Vehicle side windows tend to fog on the inside in mild
rainy or humid weather. To clear the windows, set mode
to the mix or defrost position. Direct the panel outlets
toward the side windows. Do not use recirculate without
A/C for long periods as fogging may occur.
Interior fogging on the windshield can be quickly re-
moved by using the defrost position.
If the fogging problem persists, clean the inside window
surfaces. The cause of undue fogging may be dirt collect-
ing on the inside surface of the glass.
NOTE:In cold weather, the use of the recircu-
late position will cause windows to fog on the
inside because of moisture build up inside thevehicle. For maximum defogging, press the recirculation
button until recirculate is off.
Summer Operation
Air conditioned vehicles must be protected with a high-
quality antifreeze coolant to provide proper corrosion
protection and to raise the boiling point of the coolant for
protection against overheating. A 50% concentration is
recommended.
Outside Air Intake
When operating the system during the winter months,
make sure the air intake, directly in front of the wind-
shield, is free of ice, slush, snow or other obstructions
such as leaves. Leaves collected in the air-intake plenum
may reduce air flow and plug the plenum water drains.
230 UNDERSTANDING YOUR INSTRUMENT PANEL

The blower air will heat faster in cold weather if you use
only a low blower speed for the first few minutes of
vehicle operation.
Side Window Demisters
A side window demister outlet is at each end of the
instrument panel. These nonadjustable outlets direct airtoward the side windows when the system is in either the
FLOOR, MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view the
outside mirrors.
