2009 JEEP COMPASS ECO mode

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.

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.

To turn ESP on again, momentarily depress the ESP OFF
switch. This will restore the normal “ESP On” mode of
operation.
NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the ESP OFF switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily depressing
the ESP OFF switch. This may be done while the vehicle
is in motion.
Full Off (4WD Models Only)
This mode is intended for off-highway or off-road use
when ESP stability features could inhibit vehicle maneu-
verability due to trail conditions. This mode is entered by
depressing and holding the ESP OFF switch for five
seconds when the vehicle is stopped and the engine is
running. After five seconds, the “ESP/TCS IndicatorLight” will illuminate and the “ESP Off” message will
appear in the odometer. Press and release the Trip
Odometer button located on the instrument cluster to
clear this message.
In this mode, ESP and TCS, except for the “limited slip”
feature described in the TCS section, are turned off until
the vehicle reaches a speed of 35 mph (56 km/h). At
35 mph (56 km/h) the system returns to “Partial Off”
mode, as described above. TCS remains off. When the
vehicle speed drops below 30 mph (48 km/h) the ESP
system shuts off. ESP is deactivated at low vehicle speeds
so that it will not interfere with off-road driving however,
ESP function returns to provide the stability feature at
speeds above 35 mph (56 km/h). The “ESP/TCS Indica-
tor Light” will always be illuminated when ESP is off.

E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosion
To fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have been
shown to reduce spark plug life and reduce emission
system performance in some vehicles. The manufacturer
recommends using gasolines without MMT. Since the
MMT content of gasoline may not be indicated on the
pump, you should ask your gasoline retailer whether or
not their gasoline contains MMT.

Fluid Level Check
Check the fluid level by removing the fill plug. The fluid
level should be between the bottom of the fill hole and a
point not more that 3/16 in (4.7 mm) below the bottom of
the hole.
Add fluid, if necessary, to maintain the proper level.
Frequency Of Fluid Change
Under normal operating conditions, the fluid installed at
the factory will give satisfactory lubrication for the life of
the vehicle. Fluid changes are not necessary unless lubri-
cant has become contaminated with water.
NOTE:If contaminated with water, the fluid should be
changed immediately.

Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons, are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
