Engine coolant temperature
gauge:Indicates engine coolant
temperature. At normal operating
temperature, the level indicator will
be blue and will be in the normal
range (between “H” and “C”). If the
engine coolant temperature exceeds
the normal range, the level indicator
will change to red to indicate that
the engine is overheating. Stop the
vehicle as soon as safely possible,
switch off the engine and let the engine cool.
Empower instrument cluster level only:The
indicator next to the
gauge will illuminate in green or white to indicate the following:
•
Indicator white: This indicates that the hybrid system is not
warm enough to allow operation in electric vehicle mode only. The
gasoline engine will run continuously when the indicator is white.
Note:During silent key start mode, the
indicator will be white,
but the gasoline engine will not run. This is a result of the vehicle
computer allowing the engine to be cooler during the silent key start
period. This is normal operation and does not indicate a problem with
your vehicle. After the first engine start, the
indicator will turn
green when the gasoline engine is warm enough to turn off.
•
Indicator green: This indicates that the hybrid system is warm
enough to allow operation in electric vehicle mode.
If the vehicle operates in electric mode long enough, it is possible that
the gasoline engine may need to run to keep the system warm. In this
case, the
indicator will revert back to white.
High-voltage battery information
gauge:The fill level indicates the
amount of energy stored in the
high-voltage battery as a percent of
total energy capacity. The level will
increase and decrease as the battery
charges and discharges during
normal operation, but the hybrid
system will attempt to control the
level to approximately the middle of
the gauge under most driving
conditions.

Power point (110V AC)
The 110V AC power point outlet,
located on the rear of the floor
console, is used for powering
electrical devices that require up to
150W. Exceeding the 150W limit will
cause the power point to cut off the
power temporarily to provide
overload protection.
Note:The 110V AC power point is equipped with a safety cap and a
safety twist tab. They both provide protection from inserting any object
into the power point other than the 110V AC electrical device plug. The
safety cap should always be in a closed position whenever the power
point outlet is not in use.
The power outlet is not designed for the following electric appliances;
they may not work properly:
•Cathode ray tube type televisions.
•Motor loads, such as vacuum cleaners, electric saws and other electric
power tools, compressor-driven refrigerators, etc.
•Measuring devices, which process precise data, such as medical
equipment, measuring equipment, etc.
•Other appliances requiring an extremely stable power supply:
microcomputer-controlled electric blankets, touch sensor lamps, etc.
Do not keep electrical devices plugged in the power point
whenever the device is not in use. It is not recommended to use
any extension cord with the 110V AC power point, since it will
defeat the safety protection design provided by the cap and twist
tab. It will also cause the power point to overload due to
powering multiple devices that can reach beyond the 150W load
limit.
The power point can switch to a fault mode when it is overloaded,
overheated, or shorted. For overloading and shorting conditions, unplug
your device and turn the ignition key off then on. For an overheating
condition, let the system cool off, then turn the ignition key off then on.
The 110V AC power point can provide power whenever the vehicle
ignition is in the run position and the power point green indicator light

STEERING
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill.
If your vehicle loses electrical power while you are driving (or if the
ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Under extreme usage conditions, the steering effort may
increase. This occurs to prevent overheating and permanent damage to
your steering system. If this should occur, you will neither lose the ability
to steer the vehicle manually nor will it cause permanent damage.
Typical steering and driving maneuvers will allow the system to cool and
steering assist will return to normal.
The EPS system has diagnostic checks that continuously monitor the
EPS system to ensure proper operation. When a system error is
detected, the following message SERVICE POWER STEERING, SERVICE
POWER STEERING NOW or POWER STEERING ASSIST FAULT may
display in the message center, refer to theMessage centerin theDriver
Controlschapter for more information.

improper coolant may harm engine and cooling system components
and may void the warranty. Refer toMaintenance product
specifications and capacitiesin this chapter.
Note:Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the engine cooling and/or heating systems.
This damage would not be covered under your vehicle’s warranty.
•A large amount of water without engine coolant may be added, in case
of emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained and refilled with a 50/50 mixture of
engine coolant and distilled water as soon as possible. Water alone
(without engine coolant) can cause engine damage from corrosion,
overheating or freezing.
•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 engine
coolant.
For vehicles with overflow coolant systems with a non-pressurized cap
on the coolant recovery system, add coolant to the coolant recovery
reservoir when the engine is cool. Add the proper mixture of coolant and
distilled water to the FULL COLD level. For all other vehicles which have
a coolant degas system with a pressurized cap, or if it is necessary to
remove the coolant pressure relief cap on the radiator of a vehicle with
an overflow system, follow these steps to add engine coolant.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
Add the proper mixture of coolant and water to the cooling system by
following these steps:
1. Before you begin, turn the engine off and let it cool.
2. When the engine is cool, wrap a thick cloth around the coolant
pressure relief cap on the coolant reservoir (a translucent plastic bottle).
Slowly turn cap counterclockwise (left) until pressure begins to release.
3. Step back while the pressure releases.

4. When you are sure that all the pressure has been released, use the
cloth to turn it counterclockwise and remove the cap.
5. Fill the coolant reservoir slowly with the proper coolant mixture, to
within the COLD FILL RANGE or the FULL COLD level on the reservoir.
If you removed the radiator cap in an overflow system, fill the radiator
until the coolant is visible and radiator is almost full.
6. Replace the cap. Turn until tightly installed. Cap must be tightly
installed to prevent coolant loss.
After any coolant has been added, check the coolant concentration (refer
toChecking engine coolant). If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the
concentration. It may take several drains and additions to obtain a 50/50
coolant concentration.
Whenever coolant has been added, the coolant level in the coolant
reservoir should be checked the next few times you drive the vehicle. If
necessary, add enough 50/50 concentration of engine coolant and
distilled water to bring the liquid level to the proper level.
If you have to add more than 1.0 quart (1.0 liter) of engine coolant per
month, have your authorized dealer check the engine cooling system.
Your cooling system may have a leak. Operating an engine with a low
level of coolant can result in engine overheating and possible engine
damage.
Recycled engine coolant
Ford Motor Company does NOT recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Coolant refill capacity
To find out how much fluid your vehicle’s cooling system can hold, refer
toMaintenance product specifications and capacitiesin this chapter.
Fill your engine coolant reservoir as outlined inAdding engine coolant
in this section.
Severe climates
If you drive in extremely cold climates (less than –34°F [–36°C]):
•It may be necessary to increase the coolant concentration
above 50%.

Oil, fluids and flushing
In many cases, fluid discoloration is a normal operating characteristic
and, by itself, does not necessarily indicate a concern or that the fluid
needs to be changed. However, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected
immediately by a qualified expert such as the factory-trained technicians
at your Ford or Lincoln Mercury dealership. Your vehicle’s oils and fluids
should be changed at the specified intervals or in conjunction with a
repair. Flushing is a viable way to change fluid for many vehicle
sub-systems during scheduled maintenance. It is critical that systems are
flushed only with new fluid that is the same as that required to fill and
operate the system, or using a Ford-approved flushing chemical.
