HYBRID OPERATION
This hybrid vehicle combines electric and gasoline propulsion without
compromise, to provide breakthrough performance and efficiency. It
requires no special fuels and never has to be plugged in. Familiarizing
yourself with these unique characteristics will help ensure optimal
performance from your new vehicle.
Normal vehicle operation
Starting:Turn the ignition key to
the start position while your vehicle
is in P (Park). The green “Ready
Indicator” light will appear in the
instrument cluster, letting you know
that the vehicle is ready for driving. The engine may not start because
this Hybrid vehicle is equipped with Silent Key Start (SKS). This fuel
saving feature allows your vehicle to be “ready to drive” without
requiring the gas engine to be running. This indicator will remain on
while the vehicle is on, whether the engine is running or not to indicate
the vehicle is capable of movement (using its electric motor, engine, or
both). The vehicle’s computer will determine if an engine start is
required. Typically, the engine will not start unless the vehicle is cold, a
climate control change is requested, or the accelerator is depressed.
Note:You may notice higher engine speeds upon start-up. This
temporary condition is normal and necessary to heat up the cabin and
minimize emissions.
Driving:The gas engine automatically starts and stops to provide power
when it’s needed and to save fuel when it’s not. While coasting at low
speeds, coming to a stop, or standing, the gas engine normally shuts
down and the vehicle operates in electric-only mode. Conditions that
may cause the engine to start up or remain running include:
•Considerable vehicle acceleration
•Vehicle speed above 47 mph (75 km/h)
•Ascending a hill
•Charge level of high voltage battery is low
•
Very high or low outside temperature (to provide system cooling/heating)
•Engine not warm enough to provide passenger requested cabin
temperature
Stopping:The gas engine may shut off to conserve fuel as you come to
a stop. Restarting the vehicle is not required. Simply step on the
accelerator when you are ready to drive.

Question Answer
What is the fan noise I hear from
the rear of my hybrid?The fan noise comes from a fan
located inside the high voltage
battery. This fan turns on when
the battery requires cooling air.
The fan speed, and associated
noise level, will change according
to the amount of cooling required
to maintain good performance.
Maintaining the battery
temperature at optimal conditions
also prolongs the useful life of the
battery and helps to achieve better
fuel economy.
How far can I go in Electric Drive
if I run out of gas?Running out of gas is not
recommended. However, you may
be able to go about one mile,
driving at 30 mph (48 km/h), if the
battery has a normal state of
charge.
What is the engine oil change
service interval?The engine oil should be changed
every 10,000 miles (16,000 km)
under normal operating conditions.
See theScheduled Maintenance
Guidechapter.
Can I put E10 or E85 in my
vehicle, and how will it affect my
fuel economy?Your hybrid vehicle can use E10
(10% ethanol, 90% gasoline) fuel,
but you may notice slightly
reduced fuel economy because
ethanol contains less energy per
gallon than gasoline. Your hybrid
vehicle is not designed to use E85
(85% ethanol).

WARNING:Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy Fuelsystem. This could
damage the fuel system and its seal, and may cause fuel to run onto
the ground instead of filling the tank, all of which could result in
serious personal injury.
JUMP STARTING (LOW VOLTAGE [UNDERHOOD] BATTERY ONLY)
WARNING:The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Preparing your vehicle
If your low voltage (underhood) battery becomes disconnected or
disabled for any reason, the vehicle controller must relearn the engine’s
operating characteristics in order to operate it at maximum efficiency.
This relearning process occurs the first time the vehicle is driven after
reconnecting the low voltage battery. If the learning procedure does not
have time to complete during the drive, the engine will continue to
operate for 3-5 seconds after you turn the ignition off to complete the
relearning process. This is a normal condition and will not re-occur until
the low voltage battery is disconnected again. Refer toLow voltage
(underhood) batteryin theMaintenance and Specificationchapter
for more information.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle making
sure the two vehiclesdo nottouch. Set the parking brake on both vehicles
and stay clear of the engine cooling fan and other moving parts.

ENGINE COOLANT AND MOTOR/ELECTRONICS COOLANT
Your vehicle is equipped with two separate coolant systems. One is for
engine cooling and the other is for various electric motors and other
components that are specific to the hybrid operating systems.
Checking engine coolant
The concentration and level of
engine coolant should be checked at
the intervals listed inscheduled
maintenance information. The
coolant concentration should be
maintained at 50/50 coolant and
distilled water. For best results,
coolant concentration should be
tested with a refractometer such as
Rotunda tool 300-ROB75240E
available from your dealer. Ford
does not recommend the use of
hydrometers or coolant test strips
for measuring coolant
concentration.The level of coolant
should be maintained at the FULL COLD level or within the COLD FILL
RANGE in the coolant reservoir. If the level falls below, add coolant per
the instructions in theAdding engine coolantsection. When the engine
is cold, check the level of engine coolant in the reservoir.
Checking motor/electronics (M/E) coolant
The M/E coolant reservoir is located
at the rear of the engine
compartment. Refer to the following
engine coolant sections for all
information, instructions and
warnings related to cooling systems.
The two systems use the same
coolant and operate similarly, with
the Motor and Electronics system
generally operating at a lower
temperature and pressure. The fluid
levels in both reservoirs need to be maintained. When the engine is cold,
check the level of M/E coolant in the reservoir. The coolant should be at
the FULL COLD level as shown on the side of the coolant reservoir.
