The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Stop your vehicle as soon as it is safe
to do so. Fully apply the parking brake,
shift into park (P) or neutral (N).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK - 2.3L
ECOBOOST™
Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer. Have an authorized dealer check and
change the transmission fluid at the
correct service interval. See Maintenance
(page 284). Your transmission does not
consume fluid. However, the fluid level
should be checked if the transmission is
not working properly, (i.e., if the
transmission slips or shifts slowly) or if you
notice some sign of fluid leakage.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
AUTOMATIC TRANSMISSION
FLUID CHECK - 3.5L DURATEC/
3.5L ECOBOOST™
Do not use supplemental transmission
fluid additives because they are
unnecessary and could lead to
transmission damage that may not be
covered by the vehicle Warranty.
The transmission does not consume fluid.
However, if the transmission slips or shifts
slowly you should check the fluid level. If
you notice a sign of leaking fluid, contact
an authorized dealer.
Checking the Transmission Fluid
Level WARNING:
The dipstick and
surrounding components are hot. Use
gloves when moving components and
checking the transmission fluid level.
Failure to follow this warning could result
in serious personal injury.

*
Vehicles With Turbocharged Engines WARNING: Do not start the engine
with the air filter removed. This can cause
damage not covered by the vehicle
Warranty and can result in serious injury.
1. Loosen the clamp holding the air filter assembly to the rubber hose.
2. Remove the air filter assembly securing
bolts.
3. Lift the air filter assembly to disengage
the locating pins.
4. Rotate the air filter assembly slightly in a counterclockwise direction.
5. Check the transmission fluid level.
6. Install the air filter assembly in reverse
order. Tighten the air filter assembly
securing bolts until you feel a strong
resistance.
BRAKE FLUID CHECK WARNING:
Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use of
incorrect fluid could result in the loss of
vehicle control, serious personal injury or
death. WARNING: Only use brake fluid from
a sealed container. Contamination with
dirt, water, petroleum products or other
materials may result in brake system
damage or failure. Failure to adhere to this
warning could result in the loss of vehicle
control, serious personal injury or death. WARNING: Do not allow the fluid to
touch your skin or eyes. If this happens,
rinse the affected areas immediately with
plenty of water and contact your physician. WARNING: A fluid level between the
MAX
and MIN lines is within the normal
operating range and there is no need to
add fluid. A fluid level not in the normal
operating range could compromise the
performance of the system. Have your
vehicle checked immediately. To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications.

•
Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
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.
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 battery cables are disconnected.
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.
