PLUG-IN HYBRID VEHICLE
OPERATION
Plug-in Power Mode and HybridMode
You must plug in your Energi vehicleregularly for optimal use of the highvoltage battery's extended rangecapability. Charging your vehicle addselectrical energy. This energy is used topropel the vehicle in plug-in power mode.
Estimated electric range is shown in bluenext to gasoline range at the bottom of theright information display. You can alsoconfigure MyView to include detailedvehicle range information. See Gauges(page 84).
The system maximizes the use ofelectric-only operation in plug-in powermode. System conditions may requireengine operation; however, the systemuses plug-in power whenever possible.
When your plug-in power is depleted, thepowertrain system will automaticallyswitch to hybrid mode. Hybrid mode usesboth the gasoline engine and electricmotor to power your vehicle and maximizefuel economy.
EV Modes
Your vehicle contains selectableEV modes through the EV buttonlocated on the center of theinstrument panel, below the climatecontrols.
These modes are available when yourvehicle can run under high voltage batterypower. With your vehicle in driving mode,you can change EV modes with each pressof the EV button. The current mode will bedisplayed in the left-hand instrumentcluster screen.
Auto EV
This mode provides anautomatic use of high voltagebattery power during the drive,staying in electric mode when possible andrunning the engine when needed. Thismode will be the only one available if theplug-in power has been depleted.
EV Now
This mode provides an electriconly driving experience. Theleft-hand information displaychanges to a screen displaying youraverage miles or kilometers per chargealong with EV specific tools and functions.

AnswerQuestion
Your vehicle's engine and transmission aredesigned to deliver the power you need atthe most efficient engine speed. This maybe higher than expected during heavyaccelerations, and may fluctuate whendriving at a steady speed. These are charac-teristics of the Atkinson engine cycle andthe 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 locatednext to the high voltage battery pack. Thisfan turns on when the battery requirescooling air. The fan speed, and associatednoise level, will change according to theamount of cooling required to maintaingood performance. Maintaining the batterytemperature at optimal conditions alsoprolongs the useful life of the battery andhelps to achieve better fuel economy.
What is the fan noise I hear from the rearof my hybrid?
Change the engine oil every 10000 miles(16000 kilometers) or once per year undernormal operating conditions.
What is the engine oil change serviceinterval?
Your hybrid vehicle can use E15 (15%ethanol, 85% gasoline) fuel, but you maynotice slightly reduced fuel economybecause ethanol contains less energy pergallon than gasoline. Your hybrid vehicle isnot designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and howwill it affect my fuel economy?
The high voltage battery system is designedto last the life of the vehicle and requiresno maintenance.
How long will my high voltage battery last?Does it need maintenance?
There are no provisions for charging thehigh voltage battery from a power supplyexternal to the vehicle. (For C-MAX Energivehicles, the vehicle can be plugged into a110-volt outlet with charge cord provided.)
Can you charge the battery with a plug intoan A/C outlet?
Yes. Your hybrid vehicle can be flat towedwithout modification. See Towing (page192).
Can I tow the hybrid behind my motor homewith all four wheels down?

Unique Driving Characteristics

EMISSION CONTROL SYSTEM
WARNINGS
Do not park, idle, or drive your vehiclein dry grass or other dry ground cover.The emission system heats up theengine compartment and exhaust system,which can start a fire.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your dealer inspect yourvehicle immediately. Do not drive if yousmell exhaust fumes.
Your vehicle is equipped with variousemission control components and acatalytic converter that will enable yourvehicle to comply with applicable exhaustemission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while yourvehicle is moving, especially at highspeeds.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for serviceof components affecting emission control,such non-Ford parts should be equivalentto genuine Ford Motor Company parts inperformance and durability.
Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damagedexhaust system may allow exhaust toenter the vehicle. Have a damaged orimproperly operating exhaust systeminspected and repaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehiclesare not permitted to intentionally removean emission control device or prevent itfrom working. Information about yourvehicle’s emission system is on the VehicleEmission Control Information Decallocated on or near the engine. This decalalso lists engine displacement.
Please consult your warranty informationfor complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1. Your vehicle has run out of fuel—theengine may misfire or run poorly.

Fuel and Refueling

2. Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3. The fuel fill inlet may not have closedproperly. See Refueling (page 145).
4. Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the onposition for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing,you can perform the following driving cycleconsisting of mixed city and highwaydriving:
1. 15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2. Allow your vehicle to sit for at leasteight hours with the ignition off. Then,start the vehicle and complete theabove driving cycle. The vehicle mustwarm up to its normal operatingtemperature. Once started, do not turnoff the vehicle until the above drivingcycle is complete.
If the vehicle is still not ready for I/Mtesting, you need to repeat the abovedriving cycle.

Driving Aids

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). Duringthis time, your vehicle may exhibit someunusual driving characteristics. The enginealso needs to break in. Avoid hardaccelerations and driving too fast for thefirst 1,000 mi (1,600 km). If possible, avoidcarrying heavy loads up steep gradesduring 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 vehiclein.
You may improve your fuel economy bykeeping these in mind:
•Drive your vehicle at reasonablespeeds. Traveling at 65 mph(105 km/h) uses about 15% less fuelthan traveling at 75 mph (121 km/h).
•Drive at steady speeds withoutstopping.
•Anticipate stops. Slowing down yourvehicle may eliminate the need to stop.
•Keep the tires properly inflated and useonly the recommended size.
•Switch off the heater if you do not needit. When you have the heater on, keepit at the lowest blower andtemperature setting necessary to becomfortable.
•When it is cold outside, park in a sunnylocation or a climate-controlledenvironment. This may save fuel byreducing the energy needed to heat thecabin.
•Switch off the air conditioning if you donot need it. When you have the airconditioning on, keep it at the lowestblower and highest temperaturesetting necessary to be comfortable.
•When it is hot or sunny outside, parkingin a shaded or climate-controlledenvironment will save fuel by reducingthe energy needed to cool the cabin.
•For Plug-In Hybrid vehicles, usepreconditioning to improve your fueleconomy. See High Voltage Battery(page 151).
•Switch off the heated seats if you arenot using them.
•Switch off the defroster when you nolonger need it for visibility.
•For Plug-In Hybrid vehicles, plug in andrecharge the high voltage batterywhenever possible.
•Use ECO Cruise Control, especially inhilly terrain. See Cruise Control (page177).
•Shift into low gear (L) when enhancedengine braking is needed. Otherwise,use drive gear (D) shift position.
•Combine errands and minimizestop-and-go driving. A warmed upengine works more efficiently. Whenrunning errands, go to the farthestdestination first and then work yourway back home.
•Close the windows for high-speeddriving.
•Use the recommended engine oil. SeeCapacities and Specifications (page282).
