Note:During normal vehicle operation, the coolant may change color
from orange to pink or light red. As long as the coolant is clear and
uncontaminated, this color change does not indicate the coolant has
degraded nor does it require the coolant to be drained, the system
to be flushed, or the coolant to be replaced.
•DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of coolants may harm your
cooling system. The use of an improper coolant may harm engine,
inverter system controller, and cooling system components and may
void the warranty.
•
In case of emergency, a large amount of water without engine coolant
may be added to the engine cooling system only in order to reach a
vehicle service location. In this instance, the engine cooling system must
be drained, chemically cleaned with Motorcraft® Premium Cooling
System Flush, and refilled with prediluted engine coolant as soon as
possible. Water alone (without engine coolant) can cause engine damage
from corrosion, overheating, or freezing. DO NOT use this method for
the inverter system controller cooling system. The inverter system
controller cooling system operates close to ambient temperature, and is
susceptible to freezing in any subfreezing environment in the absence of
coolant.
•Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). Alcohol and other liquids can
cause engine damage from overheating or freezing.
•Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the coolant.
Adding Engine Coolant
1. Remove the Easy Fuel funnel from the storage compartment. Refer to
Running Out of Fuelfor the location of the Easy Fuel funnel.
2. Unscrew the engine coolant reservoir cap slowly. Any pressure will
escape as you unscrew the cap.
3. Position the Easy Fuel funnel in the engine coolant reservoir opening.
Push the Easy Fuel funnel neck fully into the engine coolant reservoir,
past the vent tube, in order to avoid pouring the coolant into the vent
tube and spilling the coolant on the ground.
4. Add prediluted engine coolant to the engine coolant reservoir. Make
sure that the level is between the MIN and MAX marks on the engine
coolant reservoir. Use prediluted engine coolant meeting the Ford
specification. See the technical specifications chart in theCapacities
and Specificationschapter.

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.

BRAKE FLUID CHECK
Fluid levels between the MIN and MAX lines are within the normal
operating range; there is no need to add fluid. If the fluid levels are
outside of the normal operating range, the performance of the system
could be compromised; seek service from your authorized dealer
immediately.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric power steering system. There is
no fluid reservoir to check or fill.
FUEL FILTER
Your vehicle is equipped with a lifetime fuel filter that is integrated with
the fuel tank. Regular maintenance or replacement is not needed.
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 the technical specifications chart in
theCapacities and Specificationschapter.
Note:The front and rear washer systems are supplied from the same
reservoir.
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.

CHANGING THE LOW VOLTAGE BATTERY
Your vehicle is equipped with a Motorcraft® maintenance-free low
voltage battery which normally does not require additional water during
its life of service.
Note:See an authorized dealer for low voltage battery access, testing, or
replacement.
When a low voltage battery replacement is necessary, see an authorized
dealer to replace the low voltage battery with a Ford recommended
replacement low voltage battery that matches the electrical requirements
of the vehicle.
To ensure proper operation of the battery management system (BMS), do
not allow a technician to connect any electrical device ground connection
directly to the low voltage battery negative post. A connection at the low
voltage battery negative post can cause inaccurate measurements of the
battery condition and potential incorrect system operation.
Note:If a person adds electrical or electronic accessories or components
to the vehicle, the accessories or components may adversely affect the
low voltage battery performance and durability and may also affect the
performance of other electrical systems in the vehicle.
Note:Always dispose of automotive batteries in a responsible manner.
Follow your local authorized standards for disposal. Call your local
authorized recycling center to find out more about recycling automotive
batteries.
Because your vehicle’s engine is electronically-controlled by a computer,
some engine control settings are maintained by power from the low
voltage battery. Some engine computer settings, like the idle trim and
fuel trim strategy, optimize the driveability and performance of the
engine. Some other computer settings, like the clock and radio station
presets, are also maintained in memory by power from the low voltage
battery. When a technician disconnects and connects the low voltage
battery, these settings are erased. Complete the following procedure in
order to restore the settings:
1. With the vehicle at a complete stop, set the parking brake.
2. Shift the transmission to P (Park).
3. Turn off all accessories.
4. Step on the brake pedal and start the vehicle.
5. Step on the accelerator to start the engine.

6. Run the engine until the engine reaches normal operating
temperature. While the engine is warming up, complete the following:
•Reset the clock. SeeClockin theAudio Systemchapter.
•Reset the radio station presets. SeeNumber blockin theAudio
Systemchapter.
•Reset the power windows bounce-back feature. SeeResetting the
Bounce-Back Featurein thePower Windowssection.
7. Allow the engine to idle for at least one minute.
8. If the engine turns off, step on the accelerator to start the engine.
9. While the engine is running, step on the brake pedal and shift the
transmission to N (Neutral).
10. Allow the engine to run for at least one minute by pressing on the
accelerator pedal.
11. Drive the vehicle at least 10 miles (16 kilometers) to completely
relearn the idle and fuel trim strategy.
Note:If you do not allow the engine to relearn the idle and fuel trim
strategy, the idle quality of your vehicle may be adversely affected until the
engine computer eventually relearns the idle trim and fuel trim strategy.
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
Note:Use the service position in winter to provide easier access to the
front wiper blades for freeing them from snow and ice. The front wipers
will not return to their normal position as soon as you switch on the
ignition. The front wipers will stay in the service position when you
switch the ignition on or start the engine. Switch on the front wipers to
any mode, then switch off the front wipers to bring the front wipers back
to the park position.
Note:The windshield wiper blades are different in length. If you install
wiper blades of the wrong length, the wipers may not work correctly.
If equipped with autowipers, the rain sensor may not work correctly.
