2002 LINCOLN LS air conditioning

Turning the system off
Press OFF. The outside temperature
(EXT) function (if selected) will
continue to operate until the
ignition is turned off.
DATC automatic operation
Press AUTO and select the desired
temperature. The selected
temperature will appear in the
display window, and an indicator
above the AUTO control will light.
The DATC system will either heat or
cool the vehicle to achieve the
selected temperature. The system
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 of the defroster, 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
approximately 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), the manual override
controls allow you to select airflow locations as necessary. To return to
full automatic control, press the AUTO control.

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 speed 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 2É C (35É F) or higher. 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 defrost mode, if the outside temperature is about 2É C (35É F) or
higher, the air conditioner will automatically dehumidify the air to reduce
window 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. With automatic A/C operation, the A/C indicator will be lit if
the outside temperature is about 2É C (35É F) or higher. You may
override the automatic A/C operation at any time. To manually control
the A/C operation and cancel automatic A/C operation, press the A/C
control. When the A/C is manually controlled in the AUTO mode, the
AUTO indicator will remain lit. To return to automatic A/C operation,
press AUTO.
²Recirculation control
(air recirculation) Ð Used to manually enable or disable the
operation of the recirculated air operation in all modes except defrost.
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 DATC system to automatically control the selection of outside
or recirculated air.
The recirculation control cannot be selected in the defrost mode, as
interior fogging may occur.
In floor and floor/defrost modes, the DATC system will automatically
return to outside air to help reduce window fogging. When the
recirculation air control is selected, the amount of time in manual
recirculated air depends on the ambient temperature.

When AUTO is selected, the recirculated air feature operates automatically
for existing conditions. You may override the automatic recirculated air
operation at any time. To manually control the recirculated air operation
and cancel automatic recirculated air operation, press the recirculated air
control. When the recirculated air is manually controlled in the AUTO
mode, the AUTO indicator light will remain lit. To return to full automatic
recirculated air operation, press AUTO.
Do not leave the DATC system in recirculated air operation for extended
periods of time while the system is in a heating mode or in cold/damp
conditions as this may cause interior fogging of the front, side and rear
windows.
Manual override controls
The manual override controls allow you to manually determine where
airflow is directed. To return to fully automatic control, press AUTO.
When a manual airflow 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 compressor can operate in all modes except OFF.
However, the air conditioning will only function if the outside
temperature is about 2É C (35É 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.

(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.
When floor/defrost is selected, if the outside temperature is about 2É C
(35É F) or higher, the air conditioner will automatically dehumidify the
air to reduce window fogging. For added customer comfort, the air
distributed through the floor ducts may be slightly warmer than the air
sent to the windshield defroster ducts. When floor/defrost is selected,
the system will automatically provide outside air to reduce window
fogging. Recirculation and A/C override controls can be selected.
(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 temperature is about 2É C
(35É F) or higher, the air conditioner will automatically dehumidify the
air to reduce window 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.
Heated wiper rest
(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.

If you ever smell exhaust fumes of any kind inside your vehicle,
have your dealer inspect and fix your vehicle immediately. Do
not drive if you smell exhaust fumes. These fumes are harmful and
could kill you.
Have the exhaust and body ventilation systems checked whenever:
²the vehicle is raised for service
²the sound of the exhaust system changes
²the vehicle has been damaged in a collision
WARNING:Engine exhaust, some of its constituents, and
certain vehicle components contain or emit chemicals known to
the State of California to cause cancer and birth defects or other
reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear contain or emit chemicals known
to the State of California to cause cancer and birth defects or other
reproductive harm.
Important ventilating information
If the engine is idling while the vehicle is stopped in an open area for
long periods of time, open the windows at least 2.5 cm (one inch).
Adjust the heating or air conditioning (if equipped) to bring in fresh air.
Improve vehicle ventilation by keeping all air inlet vents clear of snow,
leaves and other debris.
BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle's brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking, the brake linings

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.
²The
symbol 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:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to a service facility.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
Never remove the coolant reservoir cap while the engine is
running or hot.
