2009 JEEP PATRIOT air condition

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 demister outlets with a small amount
through the defrost outlet.
Mix
Air is directed through the floor, defrost and side
window demister 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 demister outlets. Use this mode with
maximum fan and temperature settings for best wind-
shield and side window defrosting.
NOTE:The air conditioning compressor operates in
both Mix and Defrost 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.
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 from left (OFF)
to right.
NOTE:For vehicles equipped with Remote Start, the
climate controls will not function during Remote Start
operation if the fan control is left in the “O” (Off)
position.
Temperature Control
Use this control to regulate the
temperature of the air inside the
passenger compartment. The blue
area of the scale indicates cooler
temperatures while the red area
indicates warmer temperatures.
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.

Circulation Control
Use this button to choose between
outside air intake or recirculation
of the air inside the vehicle. A
lamp will illuminate when you
are in recirculate mode. Only use
the recirculate mode to tempo-
rarily 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 Conditioning (A/C)
A/C Operation
Use this button to engage the Air
Conditioning. A lamp will illumi-
nate when the Air Conditioning
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 de-
sired interior temperature.
NOTE:The air conditioning compressor will not engage
until the engine has been running for about 10 seconds.

MAX A/C
For maximum cooling select the
air direction to either the Panel or
Bi-Level position using the mode
control. Press the A/C button and
the recirculation button so that
both lamps are illuminated and
set the temperature control to its
coolest setting.
NOTE:
•Recirculation Mode will not operate in floor, mix or
defrost modes.
•See “Circulation Control” in this section, for proper or
extended use of this position.
Air Filtration System — If Equipped
An air filter is included in the optional Security Group.
Filter media includes a particle filtration 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 com-
partment. 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 the
vehicle. Moisture and ice can also accumulate
on the inside of the sheet metal and may result inheadliner and/or electronic component damage. 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.
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.

designated and approved. You should tread lightly and
avoid damage to the environment. You should know
your vehicles abilities and be able to recover it if some-
thing goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do
not attempt to restart it. Determine if it has ingested
water first. The key to any crossing is low and slow. You
want to use low (L Off-Road) with the 4WD LOCK
engaged and proceed very slowly with a constant slow
speed {3-5 mph (5–8 km/h) maximum} and light throttle.
Keep the vehicle moving; do not try to accelerate through
the crossing. After crossing any water higher than the
bottom of the axle differentials, you should inspect all of
the vehicle fluids for signs of water ingestion.CAUTION!
Water ingestion into the transaxle, transfer case,
engine or vehicle interior can occur if you drive too
fast or through too deep of water. Water can cause
permanent damage to engine, driveline or other
vehicle components and your brakes will be less
effective once wet and/or muddy.
Before You Cross Any Type Of Water
As you approach any type of water you need to deter-
mine if you can cross it safely and responsibly. If neces-
sary, get out and walk through the water or probe it with
a stick. You need to be sure of its depth, approach angle,
current and bottom condition. Be careful of murky or
muddy waters, check for hidden obstacles. Make sure
you will not be intruding on any wildlife and you can
recover the vehicle if necessary. The key to a safe crossing
is the water depth, current and bottom conditions. On

the slowest current can push the heaviest vehicle down-
stream out of control if the water is deep enough to push
on the large surface area of the vehicle’s body. Before you
proceed determine the speed of the current, the water’s
depth, approach angle, bottom condition and if there are
any obstacles, then cross at an angle heading slightly
upstream using the low and slow technique.
WARNING!
Never drive through fast moving deep water. It can
push your vehicle downstream, sweeping it out of
control. This could put you and your passengers at
risk of injury or drowning.
Airing Down For Off-Road Driving
Running lower tire pressure off-road can improve your
ride comfort and vehicle traction. Reducing the tire air
pressure allows the tire to bulge slightly, improving its
surface area for better flotation and ability to mold orform to the ground contour. Different terrain, tires, and
vehicles require different tire pressure. Hard surfaces like
rock and heavier vehicles require higher pressures than
softer surfaces such as sand and lighter vehicles. You will
need to experiment to determine what is right for your
situation. It is easier and faster to let air out than it is to
replace it so, start high and lower it as required. Remem-
ber you must return the tires to normal air pressure
before driving on-road or at highway conditions. Be sure
you have a way to return the tires to their normal on-road
air pressure.
CAUTION!
Reduced tire pressure increases the risk of tire dam-
age and may cause tire unseating with total loss of air
pressure. To reduce the risk of tire unseating, while at
a reduced tire pressure, drive at slower speeds and
avoid sharp turns or abrupt maneuvers.

the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning light and the ABS light remain
on, the ABS and Electronic Brake Force Distribution
(EBD) systems are not functioning. Immediate repair to
the ABS is required.
When the vehicle is driven over 7 mph (11 km/h), you
may also hear a slight clicking sound as well as some
related motor noises. These noises are the system per-
forming its self-check cycle to ensure that the ABS
working properly. This self-check occurs each time the
vehicle is started and accelerated past 7 mph (11 km/h).ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You may also experience the following when the brake
system goes into Anti-Lock mode:
•the ABS motor running (it may continue to run for a
short time after the stop)
•the clicking sound of solenoid valves
•brake pedal pulsations
•a slight drop or fall away of the brake pedal at the end
of the stop
These are all normal characteristics of ABS.
