2008 JEEP COMPASS air condition

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 dehu-
midifies 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 becauseof 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 a
charcoal 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 the
vehicle. 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.

The ABS light monitors the Anti-Lock Brake
System. The light will come on when the
ignition switch is turned to the ON position
and may stay on for as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
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 Anti-Lock brakes (ABS) and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system 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 system
is 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 also may experience the following when the brake
system goes into Anti-lock:
²The ABS motor running (it may continue to run for a
short time after the stop),
²the clicking sound of solenoid valves,
²brake pedal pulsations,

check tire pressure. Do not make a visual judgement
when determining proper inflation. Radial tires may look
properly inflated even when they are under inflated.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap (if equipped). This
will prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
Inflation pressures specified on the placard are always
ªcold tire inflation pressure.º Cold tire inflation pressure
is defined as the tire pressure after the vehicle has not
been driven for at least 3 hours, or driven less than 1 mile
(1 km) after a 3 hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall.Check tire pressures more often if subject to a wide range
of outdoor temperatures, as tire pressures vary with
temperature changes.
Tire pressures change by approximately 1 psi (7 kPa) per
12 ÉF (7 ÉC) of air temperature change. Keep this in mind
when checking tire pressure inside a garage, especially in
the winter.
Example: If garage temperature = 68 ÉF (20 ÉC) and the
outside temperature = 32 ÉF (0 ÉC) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12 ÉF (7 ÉC) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
