Answer
Question
The engine is required to turn on above thisspeed to protect the transmission hard- ware.
Why does my engine never shut down
above 85 mph (137 km/h)
In order to make sure that the climate
control system can begin heating the cabin or defrosting the windshield as soon as a driver requests it, the engine coolant
temperature has to be kept sufficiently hot. Keeping the engine on is required to main- tain the correct coolant temperature.
Why does my engine stay on when it is
extremely cold outside?
Your vehicle's engine and transmission aredesigned to deliver the power you need atthe most efficient engine speed. This may be higher than expected during heavy
accelerations, and may fluctuate when
driving at a steady speed. These are charac- teristics of the Atkinson engine cycle and the transmission technology that helpmaximize your hybrid's fuel economy.
Why does my engine rev up so high some-
times when I accelerate?
The fan noise comes from a fan located
next to the high voltage battery pack. This fan turns on when the battery requires
cooling air. The fan speed, and associated noise level, will change according to theamount 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.
What is the fan noise I hear from the rear
of my hybrid?
Change the engine oil every 10,000 mi
(16,000 km) or once per year under normal operating conditions.
What is the engine oil change service
interval?
Your hybrid vehicle can use E15 (15%
ethanol, 85% 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).
Can I put E15 or E85 in my vehicle, and how
will it affect my fuel economy?

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNINGS
Do not park, idle or drive your vehicle
on dry grass or other dry ground
cover. The emission system heats up
the engine compartment and exhaust
system, creating the risk of fire. The normal operating temperature
of the exhaust system is very high.
Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short period
of engine operation and stays hot after the
engine is switched off. WARNINGS
Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
•
Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle (page 188).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics. The engine
also needs to break in. Avoid hard
accelerations and driving too fast for the
first 1,000 mi (1,600 km). If possible, avoid
carrying heavy loads up steep grades
during the break-in period.
ECONOMICAL DRIVING
Your fuel economy depends on:
• How you drive your vehicle.
• How you maintain your vehicle.
• The conditions you drive your vehicle
in.
You may improve your fuel economy by
keeping these in mind:
• Drive your vehicle at reasonable
speeds. Traveling at
65 mph
(105 km/h) uses about 15% less fuel
than traveling at 75 mph (121 km/h).
• Drive at steady speeds without
stopping.
• Anticipate stops. Slowing down your
vehicle may eliminate the need to stop.
• Keep the tires properly inflated and use
only the recommended size.
• Switch off the heater if you do not need
it. When you have the heater on, keep
it at the lowest blower and
temperature setting necessary to be
comfortable.
• When it is cold outside, park in a sunny
location or a climate-controlled
environment. This may save fuel by
reducing the energy needed to heat the
cabin. •
Switch off the air conditioning if you do
not need it. When you have the air
conditioning on, keep it at the lowest
blower and highest temperature
setting necessary to be comfortable.
• When it is hot or sunny outside, parking
in a shaded or climate-controlled
environment will save fuel by reducing
the energy needed to cool the cabin.
• Switch off the heated seats if you are
not using them.
• Switch off the defroster when you no
longer need it for visibility.
• Shift into low gear (L) when enhanced
engine braking is needed. Otherwise,
use drive gear (D) shift position.
• Combine errands and minimize
stop-and-go driving. A warmed up
engine works more efficiently. When
running errands, go to the farthest
destination first and then work your
way back home.
• Close the windows for high-speed
driving.
• Use the recommended engine oil. See
Capacities and Specifications (page
270
).
• Perform all regularly scheduled
maintenance. See
Scheduled
Maintenance (page 415).
• Use the coach and brake coach display
to get feedback on your economical
drive style. See Information Displays
(page
92).
Avoid these actions because they reduce
your fuel economy:
• Avoid sudden or hard accelerations and
decelerations. Accelerate and slow
down in a smooth, moderate fashion.
• Avoid revving the engine before
switching off your vehicle.
• Avoid long idle periods.

To prevent engine damage under these
conditions customers should follow these
steps:
•
Drive your vehicle at full engine
temperature for 15 to 30 minutes.
• Drive your vehicle at highway speeds.
• Drive your vehicle with the defroster
(hybrid vehicles) at full.
We recommend frequent oil changes.
Follow severe duty cycle in the
maintenance guide. This helps remove the
moisture contaminated oil from the engine.
Cold Weather Operation
To determine if the shortened oil change
interval or warming of the engine is
sufficient, clean and check the oil fill cap
on a regular basis. This will confirm that
the thick milky substance is not returning.
When extreme cold weather and sub-zero
conditions exist, fuel may be found in the
engine oil. This is caused by the engine not
reaching its full engine temperature.
In this situation, carry out the above steps
to prevent engine damage.
OIL CHANGE INDICATOR
RESET (If Equipped)
Only reset the system after changing the
engine oil and oil filter.
Resetting the Oil Life Monitoring
System
1. Switch the ignition on. Do not start the
engine.
2. Fully press the accelerator and brake pedals at the same time.
3. Keep the accelerator and brake pedals
fully pressed. 4. After three seconds, a message
appears confirming that the reset is in
progress.
5. After 25 seconds, a message appears confirming that the reset is complete.
6. Release the accelerator and brake pedals.
7. Switch the ignition off.
ENGINE COOLANT CHECK WARNINGS
Never remove the coolant reservoir
cap when the engine is running or
hot.
Do not put coolant in the windshield
washer reservoir. If sprayed on the
windshield, coolant could make it
difficult to see through the windshield. 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 you loosen the cap
slightly. Do not add coolant further than the
MAX mark.
Your vehicle has two separate cooling
systems. One for cooling the engine and a
separate system for cooling the inverter
system controller that is specific to the
hybrid operating system. The two systems
operate similarly, with the inverter system
controller cooling system generally
operating at a lower temperature and
pressure.
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance
(page 415).
