the Easy Fuel™ “no cap” fuel system as it can be damaged. You must
use the included funnel in such circumstances.
WARNING:Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy Fuel™ system. 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.

7. Drive the vehicle to complete the relearning process.
•The vehicle may need to be driven 10 miles (16 km) or more to
relearn the idle and fuel trim strategy.
•If you do not allow the engine to relearn its idle trim, the idle
quality of your vehicle may be adversely affected until the idle
trim is eventually relearned.
If the battery has been disconnected or a new battery has been installed,
the clock and the preset radio stations must be reset once the battery is
reconnected.
•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.
Low and high voltage battery – storage
Your vehicle must be started and run for a minimum of 10 minutes once
a month in order to maintain the high voltage battery charge. This will
maintain the high voltage battery but it is not enough to maintain the
low voltage (underhood) battery and additional low voltage (underhood)
battery charging may be required after 60 days.
If your vehicle is to be stored for 30 days or longer, the low voltage
(underhood) battery negative terminal must be disconnected. Failure to
do this could damage your vehicle’s batteries.
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, which equates to a
freeze point of -34°F (-37°C).
Coolant concentration testing is
possible with a hydrometer or
antifreeze tester. 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.
Factory fill and coolant specifications
Your vehicle was factory-filled with a 50/50 engine coolant and water
concentration. If the concentration of coolant falls below 40% or above
60%, the engine parts could become damaged or not work properly.A
50/50 mixture of coolant and water provides the following:
•Freeze protection down to -34°F (-37°C).
•Boiling protection up to 265°F (129°C).

•Protection against rust and other forms of corrosion.
•Enables calibrated gauges to work properly.
Common instructions for cooling systems
•The engine coolant should be at the FULL COLD level or within the
COLD FILL RANGE as listed on the engine coolant reservoir
(depending upon application).
•Refer to thescheduled maintenance informationfor service interval
schedules.
•Be sure to read and understandPrecautions when servicing your
vehiclein this chapter.
If the engine coolant has not been checked at the recommended interval,
the engine coolant reservoir may become low or empty. If the reservoir is
low or empty, add engine coolant to the reservoir. Refer toAdding
engine coolantin this chapter.
Note:Automotive fluids are not interchangeable; do not use engine
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding engine coolant
When adding coolant, make sure it is a 50/50 mixture of engine coolant
and distilled water. Add the mixture to the coolant reservoir,when the
engine is cool,until the appropriate fill level is obtained. If coolant is
filled to the COLD FILL RANGE or FULL COLD level when the engine is
not cool, the system will remain underfilled.
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.

•DO NOT MIXdifferent colors or types of coolant in your vehicle.
Make sure the correct coolant is used.DO NOT MIXrecycled coolant
and new (unused) coolant together in the vehicle. Mixing of engine
coolants may harm your engine’s cooling system. The use of an
improper coolant may harm engine and cooling system components
and may void the warranty. Refer toMaintenance product
specifications and capacitiesin this chapter.
•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/–37°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 [–37°C]):
•It may be necessary to increase the coolant concentration
above 50%.
•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

Driving style — good driving and fuel economy habits
Since it is able to operate in electric mode and to collect braking energy,
your hybrid vehicle may get better fuel economy in city driving than on
the highway. This is contrary to conventional vehicles. However, many of
the same actions that improve fuel economy in a conventional vehicle
will also improve fuel economy in this vehicle.
Give consideration to the lists that follow and you may be able to
improve your fuel economy.
Habits
•Avoid aggressive driving. Quick acceleration and deceleration decrease
fuel economy.
•Drive at a smooth, constant speed. Excessive variation in pedal input
causes more operating mode changes and reduces efficiency.
•Drive at reasonable speeds. Traveling at 60 mph [96 km/h] uses
approximately 20% less fuel than traveling at 70 mph [112 km/h]).
•Minimize A/C and defroster usage. Your vehicle is equipped with an
electric A/C system, which can provide cooling for passenger comfort
or defrost without running the engine. However, the A/C system uses
battery energy when the engine is off, which reduces fuel economy.
Using Auto mode, minimizing use of defrost and Max A/C, or choosing
a higher temperature setting can help reduce energy usage.
•Minimize temperature extremes when the vehicle is parked, for
example by storing in a garage to avoid extreme cold in winter and
extreme sun loads in summer. The high voltage battery operates more
efficiently in moderate temperatures, and less energy will be spent
returning the passenger compartment to a comfortable temperature.
•Combine errands. Your vehicle is more fuel efficient when the engine
is warm. Driving to your farthest destination first will warm the engine
more quickly and may improve fuel economy for the rest of the trip.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Keep wheels properly aligned.
•Use recommended engine oil. Refer toMaintenance product
specifications and capacitiesin this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found inscheduled maintenance information.
