WINDSHIELD WIPERS
Note:
Fully defrost the windshield before
you switch the windshield wipers on.
Note: Make sure you switch the windshield
wipers off before entering a car wash.
Note: If streaks or smears appear on the
windshield, clean the windshield and the
wiper blades. If that does not resolve the
issue, install new wiper blades.
Note: Do not operate the wipers on a dry
windshield. This may scratch the glass,
damage the wiper blades or cause the wiper
motor to burn out. Always use the
windshield washers before wiping a dry
windshield. •
Rotate away from you for a long wipe
interval.
• Rotate toward you for a short wipe
interval.
Speed Dependent Wipers
When your vehicle speed increases, the
interval between wipes decreases.
AUTOWIPERS (IF EQUIPPED)
Note: Fully defrost the windshield before
you switch the windshield wipers on. Note:
Make sure you switch the windshield
wipers off before entering a car wash.
Note: If streaks or smears appear on the
windshield, clean the windshield and the
wiper blades. If that does not resolve the
issue, install new wiper blades.
Note: The courtesy wipe feature turns on
after using the windshield washers to
remove any excess washer fluid and debris.
You can adjust the courtesy wipe settings
in the instrument display.
Wet or winter driving conditions with ice,
snow or salty road mist can cause
inconsistent and unexpected wiping or
smearing. Use the rotary control to adjust the
sensitivity of the autowipers. When you
select low sensitivity, the wipers operate
when the sensor detects a large amount
of water on the windshield. When you
select high sensitivity, the wipers operate
when the sensor detects a small amount
of water on the windshield.
Keep the outside of the windshield clean.
The rain sensor is very sensitive and the
wipers may operate if dirt, mist or insects
hit the windshield.

In these conditions, you can do the
following:
•
Lower the sensitivity of the autowipers
to reduce the amount of smearing on
the windshield.
• Switch to normal or high-speed wipe.
• Switch autowipers off.
WINDSHIELD WASHERS •
A brief press causes a single wipe
without washer fluid.
• A brief press and hold causes the
wipers to swipe three times with
washer fluid.
• A long press and hold turns on the
wipers and washer fluid for up to 10
seconds.
A wipe occurs a few seconds after washing
to clear any remaining washer fluid. You
can switch this feature on or off in the
information display. See Information
Displays (page 110).
Note: Do not operate the washers when
the washer reservoir is empty. This could
cause the washer pump to overheat.

B. Halogen headlamp.
6. Repeat steps 3 thru 5 to adjust the
other headlamp.
7. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
WASHER FLUID CHECK WARNING: If you operate your
vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 441).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.
FUEL FILTER - 6.2L/7.3L
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed. CHECKING THE WIPER
BLADES
Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
You can manually move the wiper arms
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.
1. Pull the wiper blade and arm away
from the glass.

Engine
•
Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast
idle with the climate controls set to
defrost until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Disconnecting Your 12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting.
Note: It is necessary to reset memory
features if you disconnect the battery
cables. Brakes
•
Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
