2000 LINCOLN LS air conditioning

will automatically determine the fan speed, airflow location and whether
outside or recirculated air is required.
When in AUTO and weather conditions require heat, the DATC directs
the majority of the airflow to the floor area. The system will allow some
airflow out the defroster and demister outlets and outer instrument
panel registers in order to reduce window fogging. Additionally, if the
engine is not warm enough to provide heat, the fan will operate at a low
speed and the airflow will be directed to the windshield or to the floor.
In 3
1¤2minutes or less, the fan speed will start to increase and the airflow
location will change to the floor area.
When in AUTO mode, the DATC system automatically controls the air
conditioning operation, the fan speed, the airflow direction and
determines whether outside or recirculated air is required. Manual
control of the A/C, air recirculation and fan speed are available in auto
mode.
If unusual conditions exist (i.e.-window fogging, etc.), the manual
override controls allow you to select airflow locations as necessary. To
return to full automatic control, press the AUTO control.
DATC system AUTO temperature balance
Press and hold the AUTO control for about two seconds to equalize the
passenger set temperature with the driver side temperature. This feature
is useful when the driver is alone in the vehicle.

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 DATC system will return to full
automatic operation.
²A/C control
A/C(air conditioning) Ð Used to manually enable or disable the
operation of the air conditioning in all modes except defrost. In all
modes, the air conditioning will only function if the outside temperature
is about 2ÉC (35ÉF) or higher.
When manual A/C is selected (ON) the indicator will be lit. When manual
A/C is selected (OFF) the indiator will not be lit.
In defrost or floor/defrost mode, if the temperature is about 2ÉC (35ÉF)
or higher, the air conditioner will automatically dehumidify the air to
reduce fogging. However, the A/C indicator will be off and the A/C
override control cannot be selected.
When AUTO is selected, the A/C operates automatically for existing
conditions. You may override the A/C at any time. To manually control
the A/C, press the A/C control to cancel the A/C automatic operation.

In AUTO mode, the air conditioner will operate automatically. When the
A/C is adjusted in the AUTO mode, the AUTO indicator will remain lit
and the system will remain in AUTO operation.
²Recirculation control
(air recirculation) Ð The recirculation feature is used to
manually select whether the DATC system uses outside or recirculated
air. 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
unwanted odors from the outside from reaching the vehicle interior. It is
recommended to allow the DATC system to automatically control the
selection of outside or recirculated air.
The recirculation mode cannot be selected in the defrost mode, as
interior fogging may occur. When the recirculation and floor/defrost
override modes are selected, the DATC system will automatically return
to outside air to help reduce window fogging.
In AUTO mode, the air recirculation feature will operate automatically.
However, the air recirculation indicator will be off. The selection of the
air recirculation override control will automatically enable a manual
airflow override.
DO NOT leave the DATC system in recirculated air mode for extended
periods of time while the system is in a heating mode or in cold or damp
conditions as this may cause interior fogging of the front, side and rear
windows.
In AUTO mode, the air conditioner will operate automatically. When the
fan is adjusted in the AUTO mode, the AUTO indicator will remain lit,
and the system will remain in A/C operation.

Manual override controls
The override controls allow you to:
²manually control where the airflow is directed.
²manually control the air conditioning operation.
²turn the DATC system OFF.
²manually select between outside or recirculated air.
To return to full automatic control, press AUTO.
When a manual override control is selected, the DATC system will turn
off the AUTO indicator and display the indicators of all operating
override controls. More than one override control indicator may turn on
when an override control is selected.
The air conditioning can operate in all modes except OFF. However, the
air conditioning will only function if the outside temperature is about 2ÉC
(35ÉF) 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.
²Airflow direction control
(panel) Ð Distributes air through the instrument panel, and center
console registers.
(panel/floor) Ð Distributes air through the instrument panel and
center console registers, and the front and rear seat floor ducts. For
added customer comfort, the air distributed through the floor ducts may
be slightly warmer than the air sent to the instrument panel registers.
(floor) Ð Distributes air through the front and rear seat floor ducts.
The system will allow some airflow out the defroster ducts, the demister
outlets and outer instrument panel registers.

(floor/defrost) Ð Distributes air through the windshield defroster
ducts, the demister outlets and the front and rear seat floor ducts. The
system will allow some airflow out the outer instrument panel registers.
If the temperature is about 2ÉC (35ÉF) or higher, the air conditioner will
automatically dehumidify the air to reduce fogging when manually
selected. For added customer comfort, the air distributed through the
floor ducts may be slightly warmer than the air sent to the windshield
defroster ducts.
(defrost) Ð Distributes outside air through the windshield
defroster ducts and the demister outlets. It can be used to clear ice or
fog from the windshield. The system will allow some airflow out the
outer instrument panel registers. If the outside air temperature is about
2ÉC (35ÉF) 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.) Recirculation and A/C override
controls cannot be selected.
²Turn DATC off
OFF-Outside air is shut out. The fan, heating and air conditioning will
not operate. The outside temperature will still display when selected
with the ignition in the RUN position.
Electric window heaters
(heated wiper rest) Ð Located at the base of the windshield, this
feature heats the front glass area below the area heated by the front
defroster where the windshield wipers sit in their parked position. When
activated, the feature keeps the wiper blades warm and reduces the
chance of ice build up on the blades. The indicator will light when the
feature is in operation.
With the ignition in RUN and the engine running, the feature will be
automatically enabled if the temperature is below 5ÉC (40ÉF). The
feature can be manually selected or deselected at any time.
In cold, dry conditions where wet snow or ice is not present it is
acceptable to manually deselect the operation of this feature.
The feature will run continuously unless a low battery condition is
detected, or unless the feature is manually deselected, and will only
activate when the vehicle engine is running (to prevent excessive drain
of the vehicle battery).

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
What you should know about fail-safe cooling
If the engine coolant supply is depleted, this feature allows the vehicle to
be driven temporarily before incremental component damage is incurred.
The ªfail-safeº distance depends on ambient temperatures, vehicle load
and terrain.
How fail-safe cooling works
If the engine begins to overheat:
²the engine coolant temperature
gauge will move to the H (hot)
area.
²the
symbol will illuminate.
²the
symbol will illuminate.
²theCheck Engineindicator light
will illuminate.
If the engine reaches a preset over-temperature condition, the engine
will automatically switch to alternating cylinder operation. Each disabled
cylinder acts as an air pump and cools the engine.
When this occurs the vehicle will still operate. However:
²the engine power will be limited.
²the air conditioning system will be disabled.
Continued operation will increase the engine temperature and the engine
will completely shut down, causing steering and braking effort to
increase
Once the engine temperature cools, the engine can be re-started. Take
your vehicle to a service facility as soon as possible to minimize engine
damage.
When fail-safe mode is activated
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
