2002 Mercury Mountaineer air conditioning

Compasscalibrationadjustment
Perform this adjustment in an open area free from steel structures and
high voltage lines:
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
1. Start the vehicle.
2. Locate compass sensor mounted at base of mirror.
3. Insert a paperclip into the small
hole on the bottom of the compass
sensor or press the button on the
top of the compass module until
ZONE appears in the instrument
cluster display. Continue to hold
down until ZONE disappears and CAL is displayed (approximately eight
seconds) and release.
4. Drive the vehicle slowly (less than 5 km/h [3 mph]) in circles until
CAL indicator turns off (4–5 complete circles).
5. The compass is now calibrated.
MESSAGE CENTER (IF EQUIPPED)
With the ignition in the ON position,
the message center, located on your
instrument cluster, displays
important vehicle information
through a constant monitor of
vehicle systems.You may select
display features on the message center for a display of status preceded
by a brief indicator chime. The system will also notify you of potential
vehicle problems with a display of system warnings followed by a long
indicator chime.

vehicle crosses multiple zones. A correct zone setting will eliminate this
error. Refer toCompass zone/calibration adjustment.
Compass zone/calibration adjustment
Perform this adjustment in an open area free from steel structures and
high voltage lines.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
1. Turn ignition to the ON position.
2. Start the engine.
3. Determine your magnetic zone by
referring to the zone map.
4. From Info menu, select the

not select Trip, DTE, or AFE. The
top of the message center must be
blank).
5. Press and hold the RESET and
SETUP control until the message
center display changes to show the
current zone setting.
6. Release the RESET AND SETUP
control, then slowly press RESET
down again.
7. Press the SETUP control
repeatedly until the correct zone
setting for your geographic location is displayed on the message center.

CLIMATE CONTROL SYSTEM
Manual heating and air conditioning system (if equipped)
Fan speed control
Controls the volume of air circulated
in the vehicle.
Temperature control knob
Controls the temperature of the
airflow inside the vehicle.
Mode selector control
Controls the direction of the airflow
to the inside of the vehicle.
The air conditioning can operate in all modes. However, the air
conditioning will only function if the outside temperature is about 6°C
(43°F) or higher.

Since the air conditioner removes considerable moisture from the air
during operation, it is normal if clear water drips on the ground under
the air conditioner drain while the system is working and even after you
have stopped the vehicle.
•MAX A/C-Uses recirculated air to cool the vehicle. MAX A/C is noisier
than A/C but more economical and will cool the inside of the vehicle
faster. Airflow will be restricted to instrument panel registers. This
mode can also be used to prevent undesirable odors from entering the
vehicle. When placed in MAX A/C, the A/C indicator will be
illuminated and cannot be manually disabled.
•
(Panel)-Distributes outside air through the instrument panel
registers. Heating and air conditioning capabilities are provided in this
mode. Push the A/C control in order to cool the vehicle below the
outside temperature. For added customer comfort, the system will
allow some airflow through the floor ducts in this mode.
•OFF (0)-Outside air is shut out and the fan will not operate. For short
periods of time only, use this mode to prevent undesirable odors from
entering the vehicle.
•
(Panel and floor)-Distributes outside air through the instrument
panel registers and the floor ducts. Heating and air conditioning
capabilities are provided in this mode. Push the A/C control in order
to cool the vehicle below the outside temperature. For added
customer comfort, when the temperature control knob is anywhere in
between the full hot and full cold positions, the air distributed through
the floor ducts will be slightly warmer than the air sent to the
instrument panel registers.
•
(Floor)-Distributes outside air through the floor ducts. Heating
and air conditioning capabilities are provided in this mode. Push the
A/C control in order to cool the vehicle below the outside
temperature.
•
(Floor and defrost)-Distributes outside air through the windshield
defroster ducts and the floor ducts. Heating and air conditioning
capabilities are provided in this mode. For added customer comfort,
when the temperature control knob is anywhere in between the full
hot and full cold positions, the air distributed through the floor ducts
will be slightly warmer than the air sent to the windshield defrost
ducts. If the outside temperature is about 6°C (43°F) or higher, the air
conditioner will automatically dehumidify the air to reduce fogging.
(Note that the A/C indicator does not illuminate when this mode is
selected.)

•(Defrost)-Distributes outside air through the windshield defroster
ducts. It can be used to clear ice or fog from the windshield. If the
outside temperature is about 6°C (43°F) or higher, the air conditioner
will automatically dehumidify the air to reduce fogging. (Note that the
A/C indicator does not illuminate when this mode is selected.) For
added customer comfort, the system will allow some airflow through
the floor ducts in this mode.
Cooling your vehicle with outside air
Cooling your vehicle with air conditioned outside air is quieter but less
economical than using recirculated air. It also has less cooling capacity.
In order to cool your vehicle using outside air:
1. Turn the mode selector to
,or.
2. Press
A/C. (The indicator light will illuminate.)
3. Turn the temperature control knob to the left.
4. Turn the fan speed control to the position of your choice.
During periods of high humidity, vapor may be emitted from the air
outlets when using the A/C system with outside air. This can be
corrected by using MAX A/C to cool the vehicle.
•A/C control
This control is used to manually enable or disable the operation of the
air conditioning in all modes except
,and MAX A/C.
When manual A/C is selected (ON) the indicator will be lit. When manual
A/C is selected (OFF) the indicator will not be lit.
In
and, if the outside temperature is about 6°C (43°F) or
higher, the air conditioner will automatically dehumidify the air to reduce
fogging. However, the A/C indicator will not illuminate.
When placed in MAX A/C, the A/C indicator will illuminate automatically
and cannot be manually disabled.

Fan speed ()
When AUTO is pressed, fan speed is adjusted automatically for existing
conditions. You can override fan speed at any time. To control fan speed
manually, press the fan control to cancel the automatic fan speed
operation. Press the control up for higher fan speed or down for lower
fan speed. The display will show
and a bar graph to indicate manual
fan operation and relative speed.
When the fan is adjusted in the AUTO mode, the AUTO indicator will
remain lit and the system will remain in auto operation.
To return to automatic fan operation, press AUTO. The fan icon and bars
will disappear from the display, and the DEATC system will return to full
automatic operation.
•A/C control
A/C(air conditioning)—Used to manually enable or disable the
operation of the air conditioning in all modes except

all modes, the air conditioning will only function if the outside
temperature is about 6°C (43°F) or higher. When manual A/C is selected
(ON) the indicator will be lit. When manual A/C is selected (OFF) the

when in AUTO operation, the DEATC system will be disabled and you
will return to manual operation with the A/C indicator lit.
To return to automatic A/C operation, press AUTO.
•Recirculation control
(air recirculation)—Used to manually enable or disable
recirculated air operation in all modes except
and. The use of
recirculated air when the air conditioning is operating helps to reduce
the amount of time to cool down the interior of the vehicle in very hot
conditions. Recirculated air may also help to keep undesired outside
odors from reaching the vehicle interior. It is recommended to allow the
DEATC system to automatically control the selection of outside or
recirculated air.
The recirculation control cannot be selected in

fogging may occur.
When AUTO is selected, the recirculated air feature operates
