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.

N (Neutral)
With the gearshift lever in N (Neutral), the vehicle is free to roll; hold
the brake pedal down while in this position. Because of the unique
nature of the hybrid vehicle, the engine will not start in the N (Neutral)
position.
The vehicle does not charge the high voltage battery in the N
(Neutral) position. Do not idle the vehicle in N (Neutral) for
extended periods as this will discharge your high voltage battery.
D (Drive)
The normal driving position for the best fuel economy.
L (Low)
•Provides maximum engine braking.
•The transmission may be shifted into L (Low) at any vehicle speed.
WARNING:When parking, do not use the gearshift in place of
the parking brake. Always set the parking brake fully and make
sure that the gearshift is securely latched in P (Park). Turn off the
ignition whenever you leave your vehicle. Never leave your vehicle
unattended while it is running. If you do not take these precautions,
your vehicle may move unexpectedly and injure someone.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting between forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
REVERSE SENSING SYSTEM (IF EQUIPPED)
The Reverse Sensing System (RSS) sounds a tone to warn the driver of
obstacles near the rear bumper when the R (Reverse) is selected and the
vehicle is moving at speeds less than 3 mph (5 km/h). The system is not

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%.
Maintenance and Specifications
286
2010 Fusion Hybrid(hfv)
Owners Guide, 3rd Printing
USA(fus)

•NEVER increase the coolant concentration above 60%.
•A coolant concentration of 60% will provide freeze point
protection down to -62°F [-52°C]. Increased engine coolant
concentrations above 60% will decrease the overheat
protection characteristics of the engine coolant and may cause
engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate freeze protection at the temperatures in which you
drive in the winter months.
If you drive in extremely hot climates:
•It is still necessary to maintain the coolant concentration
above 40%.
•NEVER decrease the coolant concentration below 40%.
•A coolant concentration of 40% will provide freeze point
protection down to -12°F [-24°C]. Decreased engine coolant
concentrations below 40% will decrease the corrosion/freeze
protection characteristics of the engine coolant and may cause
engine damage.
•If available, refer to the chart on the coolant container to
ensure the coolant concentration in your vehicle will provide
adequate protection at the temperatures in which you drive.
Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system
and engine protection.
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.
WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS
