air conditioning LINCOLN NAVIGATOR 2013 Owners Manual

When this button is pressed, the display only shows the rear temperature
setting. After the rear setting changes are completed on the front
control, the display automatically shows both climate settings.
F.Passenger temperature control:Press and turn to increase or
decrease the air temperature on the passenger side of the vehicle.
G.Rear defrost:Press to turn the heated windows and mirrors on and
off. SeeHeated windows and mirrorslater in this chapter for more
information.
H.Auxiliary climate control fan speed:Press to turn on the auxiliary
climate control system or to adjust the rear fan speed from the front
control.
I.Recirculated air:Press to switch between outside air and
recirculated air. Using recirculated air can reduce the time needed to
cool the interior and reduce unwanted odors from entering your vehicle.
J.A/C:Press to turn air conditioning on or off. Air conditioning cools the
vehicle using outside air. To improve air conditioning when starting your
vehicle, drive with the windows slightly open for two to three minutes.
K.Footwell/Defrost:Distributes air through the windshield defroster
vents, demister vents and floor vents.
L.Footwell:Distributes air through the floor vents.
M.Instrument panel/Footwell:Distributes air through the instrument
panel vents, floor vents, and demister vents.
N.Instrument panel:Distributes air through the instrument panel
vents.
O.Manual override controls:Press buttons I through P to override
automatic control (AUTO). To return to automatic operation, press
AUTO.
P.Front fan speed control:Controls the volume of air circulated in
your vehicle. Press to increase or decrease fan speed.
Q.OFF:Turn the climate control system off. When the system is off,
outside air is prevented from entering the vehicle.
R.Driver temperature control:Press to turn the climate control
system on and off. Turn to increase or decrease the air temperature for
the driver side of the vehicle.
This control also adjusts the passenger side temperature when dual zone
operation is disengaged.

DUAL AUTOMATIC TEMPERATURE CONTROL SYSTEM WITH
HEATED AND COOLED SEATS
A.AUTO:Press to turn on fully automatic operation. Select the desired
temperature using the temperature control. The system automatically
determines fan speed, air distribution, A/C operation, and outside or
recirculated air, to heat or cool the vehicle to maintain the selected
temperature.
B.A/C:Press to turn air conditioning on or off. Air conditioning cools
the vehicle using outside air. To improve air conditioning when starting
your vehicle, drive with the windows slightly open for two to three
minutes.
C.EXT:Press to display the outside temperature. Press again to display
the interior temperature.
Note:The exterior temperature reading is more accurate when the
vehicle is moving.
D.Recirculated air:Press to switch between outside air and
recirculated air. Using recirculated air can reduce the time needed to
cool the interior and reduce unwanted odors from entering your vehicle.
E.Defrost:Distributes air through the windshield defroster vents and
demister vents. This setting can also be used to defog and clear the
windshield of a thin covering of ice.

If you drive in extremely hot climates:
•It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
•A coolant concentration of 40% will provide improved overheat
protection. Engine coolant concentrations below 40% will decrease the
corrosion/freeze protection characteristics of the engine coolant and
may cause engine damage.
Vehicles driven year-round in non-extreme climates should use
prediluted engine coolant 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 “fail-safe” distance depends on ambient temperatures, vehicle load
and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the engine coolant temperature gauge
will move to the red (hot) area and:
The coolant temperature warning light will illuminate.
The service engine soon indicator 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:
•The engine power will be limited.
•The 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 restarted. Take
your vehicle to an authorized dealer as soon as possible to minimize
engine damage.
