MANUAL HEATING AND AIR CONDITIONING SYSTEM
(IF EQUIPPED)
1.Fan speed adjustment:Controls
the volume of air circulated in the
vehicle.
2.Temperature selection:
Controls the temperature of the
airflow in the vehicle.
3.Air flow selections:Controls the direction of the airflow in the
vehicle. See the following for a brief description on each control.
MAX A/C:Uses recirculated air to cool the vehicle. Air flows from the
instrument panel vents only. This mode will help prevent unpleasant
odors from entering the vehicle.
NORM A/C:Uses outside air to cool the vehicle. Air flows from the
instrument panel vents only.
VENT: Distributes outside air through the instrument panel vents.
OFF: Outside air is shut out and the fan will not operate.
FLOOR: Distributes outside air through the floor vents.
MIX: Distributes outside air through the windshield defroster vents, floor
vents and side window demisters.
:Distributes outside air through the windshield defroster vents and
the side window demisters.
Operating tips
•To reduce fog build up on the windshield during humid weather, place
the air flow selector in the
position.
•To reduce humidity build up inside the vehicle: do not drive with the
air flow selector in OFF or MAX A/C.
•Under normal weather conditions, do not leave the air flow selector in
MAX A/C or OFF when the vehicle is parked. This allows the vehicle
to “breathe” using the outside air inlet vents.
•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.
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 position reduce blower fan speed from the highest setting
and put the vehicle’s transmission into the park gear position to continue
to receive cool air from your A/C system.
To aid in side window defogging/demisting in cold weather:
1. Select NORM A/C.
2. Adjust the temperature control to maintain comfort.
3. Set the fan speed to HI.
4. Direct the outer instrument panel vents towards the side windows.
To increase airflow to the outer instrument panel vents, close the vents
located in the middle of the instrument panel.
ELECTRONIC AUTOMATIC TEMPERATURE CONTROL (EATC)
SYSTEM (IF EQUIPPED)
1.OFF:Outside air is shut out and
the fan will not operate.
2.AUTOMATIC:Press
AUTOMATIC and select the desired
temperature using the temperature
controls. The system will automatically determine fan speed, airflow
location, and outside or recirculated air to heat or cool the vehicle to the
selected temperature. The fan speed will remain automatic unless the
thumbwheel is turned all the way to LO.

10.Outside Temp:Press to display
the outside temperature. It will
remain in the display until pressed
again. The temperature will be most accurate when the vehicle is in
motion.
11.Temperature control:Press this control to select the temperature.
The display window indicates the selected temperature.
Fahrenheit/Celsius temperature:Press MAX A/C and DEF
simultaneously to toggle between Fahrenheit and Celsius temperature.
The set point temperatures in Celsius will be displayed in half-degree
increments.

REAR WINDOW DEFROSTER
The rear defroster control is located
on the instrument panel.
Press the rear defroster control to
clear the rear window of thin ice
and fog. A small LED will illuminate
when the rear defroster is activated.
The ignition must be in the on position to operate the rear window
defroster.
The defroster turns off automatically after a predetermined amount of
time or when the ignition is turned off. To manually turn off the
defroster, press the control again.
Activating the rear window defroster will also activate the heated mirrors
(if equipped). For more information refer toHeated outside mirrorsin
theDriver Controlschapter.
Do not use razor blades or other sharp objects to clean the inside
of the rear window or to remove decals from the inside of the
rear window. This may cause damage to the heated grid lines and
will not be covered by your warranty.

INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING
Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic passenger car tires. They do
not apply to deep tread, winter-type snow tires, space-saver or
temporary use spare tires, light truck or “LT” type tires, tires with
nominal rim diameters of 10 to 12 inches or limited production tires as
defined in Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Ford Motor Company to give you
the following information about tire grades exactly as the government
has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one
and one-half (1
1 2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.

Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Inspect all your tires, including the spare, frequently, and
replace them if one or more of the following conditions exist:
Tire wear
When the tread is worn down to
1/16th of an inch (2 mm), tires must
be replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or “wear bars”, which
look like narrow strips of smooth
rubber across the tread will appear
on the tire when the tread is worn
down to 1/16th of an inch (2 mm).
When the tire tread wears down to
the same height as these “wear bars”, the tire is worn out and must be
replaced.
Damage
Periodically inspect the tire treads and sidewalls for damage (such as
bulges in the tread or sidewalls, cracks in the tread groove and
separation in the tread or sidewall). If damage is observed or suspected
have the tire inspected by a tire professional. Tires can be damaged
during off-road use, so inspection after off-road use is also
recommended.
WARNING: Age
Tires degrade over time depending on many factors such as
weather, storage conditions, and conditions of use (load, speed,
inflation pressure, etc.) the tires experience throughout their lives.
In general, tires should be replaced after six years regardless of tread
wear. However, heat caused by hot climates or frequent high loading
conditions can accelerate the aging process and may require tires to be
replaced more frequently.
You should replace your spare tire when you replace the road tires or
after six years due to aging even if it has not been used.
