F.A/C:Press the button 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.
Use A/C with recirculated air to improve cooling performance and
efficiency.
Note:A/C turns on automatically in MAX A/C, Defrost and Floor/Defrost.
G.Power:Press to turn the system on and off. When the system is off,
outside air is prevented from entering the vehicle.
H.AUTO:Press the button 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.
I.Rear defrost:Turns the heated rear window on and off. Refer to
Heated rear windowlater in this chapter for more information. If your
vehicle is equipped with heated mirrors, this button turns them on also.
J.Defrost:Distributes air through the windshield defroster vents and
de-mister vents. This setting can also be used to defog and clear the
windshield of a thin covering of ice.
GENERAL OPERATING TIPS
•To reduce fog build-up on the windshield during humid weather, select
Defrost. Temperature and fan speed can also be increased to improve
clearing.
•To reduce humidity build-up inside the vehicle, do not drive with the
system off or with recirculated air engaged.
•Do not put objects under the front seats that will interfere with the
airflow to the back seats.
•Remove any snow, ice or leaves from the air intake area at the base of
the windshield.
•To improve the A/C cool down, drive with the windows slightly open
for 2-3 minutes after start up or until the vehicle has been aired out.
•A small amount of air may be felt from the floor vent regardless of the
air distribution setting that is selected.
During extreme high ambient temperatures when idling stationary for
extended periods of time in gear, it is recommended to run the A/C in
the MAX A/C mode, adjust the blower fan speed to the lowest setting
and put the vehicle’s transmission into the P (Park) position to continue
to receive cool air from your A/C system.

Severe climates
If you drive in extremely cold climates:
Note:It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
Note:A coolant concentration of 60% will provide improved freeze point
protection. Increased engine coolant concentrations above 60% will
decrease the overheat protection characteristics of the engine coolant
and may cause engine damage.
If you drive in extremely hot climates:
Note:It may be necessary to have a Ford authorized dealer decrease the
coolant concentration to 40%.
Note:A coolant concentration of 40% will provide improved overheat
protection. Decreased 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.

E.MAX A/C:Touch to cool the vehicle with recirculated air. Touch again
for normal A/C operation. MAX A/C:
•Distributes air through instrument panel vents.
•Is more economical and efficient than normal A/C mode
•May help reduce odors from entering the vehicle.
F.A/C:Touch to turn the air conditioning on or off.
•Use with recirculated air to improve cooling performance and
efficiency.
•Engages automatically in MAX A/C, defrost and floor/defrost.
G.AUTO:Touch to engage automatic operation, then set the
temperature using the temperature control. The system automatically
controls:
•Fan speed
•Airflow distribution
•A/Conoroff
•Outside or recirculated air
H.Rear defroster:Touch to turn the rear window defroster and heated
mirrors (if equipped).
I.Defrost:Touch to clear the windshield of fog and thin ice. Touch again
to return to the previous airflow selection. When on, defrost:
•Provides outside air to reduce window fogging.
•Distributes air through the windshield defroster vents and demister
vents.
J.Manual controls:Select any of the following airflow distribution
modes:
•Floor/Defrost: Distributes air through the windshield defroster vents,
demister vents, floor vents and rear seat floor vents, and provides
outside air to reduce window fogging.
•Panel: Distributes air through the instrument panel vents.
•Panel/Floor: Distributes air through the instrument panel vents,
demister vents, floor vents and rear seat floor vents.
•Floor: Distributes air through the demister vents, floor vents and rear
seat floor vents.
