Efficiency Leaves
Efficiency leaves indicate short term drivingefficiency measured over the last fewminutes. The more leaves and vines thatappear on the display, the better your fueleconomy. Leaves and vines will occasionallyappear and disappear to indicate a changein your driving efficiency.
Flowers appear on the efficiency leavesscreen in addition to the leaves and vines.The flowers indicate long term drivingefficiency. The more flowers that appear onthe display, the more efficiently you havedriven. Once earned, the flowers will remainunless reset, unlike the leaves, which comeand go as your short term fuel economychanges.
Flowers can be reset in the informationdisplays settings menu under Driving History.See General Information (page 112).
Fuel History
From left to right this view includes aninstantaneous fuel economy gauge, historicalfuel economy data and average fueleconomy. The historical data represents anaverage over time intervals of either 1, 2 or6 minutes, with the leftmost interval beingthe most recent. Shown at the bottom of the

view is the total time duration for the 5intervals. You can select total duration in theoptions menu. Intervals shown in grey colorare from the previous drive. The bluehorizontal line represents the average fueleconomy value shown to the right.
Note:Hold OK to reset fuel history andaverage fuel economy.
Coach
This view provides a comparison of yourrecent acceleration, braking and cruisingbehavior, then recommends the mostefficient use of energy under presentconditions. The horizontal bars fill from leftto right with best behavior and appear bluewhen at least half full. When the bars are lessthan half full, the color is amber, suggestingthat you need a change in your drivingbehavior to achieve better energy efficiency.
Note:Fuel Economy will be impacted by youruse of brakes, accelerator and accessories,as well as environmental conditions such ashills and weather.
Note:Fuel economy is not always a measureof appropriate driving behavior. For example,when driving uphill and maintaining anappropriate speed, your instant fueleconomy may not be good (losing leaves)but the Coach may show a blue bar forAcceleration and Cruising.
Common Displays
Both Average fuel economy and aninstantaneous fuel economy gauge areincluded in Engage, Empower and MyView(if selected) on the left information display.They are also included in Fuel History on theright information display.
Average Fuel Economy
Average Fuel Economy is continuouslyaveraged since the last reset. You can resetyour average fuel economy by pressing andholding the OK button on the correspondingsteering wheel controls.

3. Press and hold the function button youwant to program for 2 seconds, thenrelease. Repeat this step. Depending onyour brand of garage door opener, youmay need to repeat this sequence a thirdtime.
Gate Operator / Canadian Programming
Canadian radio-frequency laws requiretransmitter signals to “time-out” (or quit) afterseveral seconds of transmission – which maynot be long enough for HomeLink to pick upthe signal during programming. Similar tothis Canadian law, some U.S. gate operatorsare designed to “time-out” in the samemanner.
Note:If programming a garage door openeror gate operator, it is advised to unplug thedevice during the “cycling” process toprevent possible overheating.
1. Press and release, every two seconds,your hand-held transmitter until theHomeLink indicator light changes to arapidly blinking or continuously on light.
2.Release the hand-held transmitter button.
3. Continue programing HomeLink. SeeIn-Vehicle Programming, Step 4.
Erasing the Function Button Codes
Note:You cannot erase individual buttons.
1. Press and hold the outer two functionbuttons simultaneously for approximately10 seconds until the indicator light abovethe buttons flashes rapidly.
2.When the indicator light flashes, releasethe buttons. You erased the codes for allbuttons.
Reprogramming a Single Button
To program a device to a previously trainedbutton, follow these steps:
1. Press and hold the desired button. DoNOT release the button.

Transmission Operation:
Due to the technologically advanced,electronically-controlled continuouslyvariable transaxle, you will not feel shiftchanges like those of a non-hybrid vehicle.
Note:Since engine speed is controlled bythe transmission, it may seem elevated attimes. This is normal hybrid operation andhelps deliver fuel efficiency andperformance.
Neutral:
We recommend that you do not idle thevehicle in neutral (N) for an extended periodof time because this will discharge your highvoltage battery, shut off your air conditioningand heating, and decrease fuel economy.The engine will not start or stop, and cannotprovide power to the hybrid system in neutral(N).
Low:
Low (L) is designed to mimic the enhancedengine braking available in non-hybridvehicles. Low gear will produce high enginespeeds to provide necessary engine braking.This is normal and will not damage yourvehicle. In low gear, the gas engine willremain on more often than in drive (D).
Reverse:
In reverse (R), vehicle speed is limited to22 mph (35 km/h).
Battery:
Your hybrid is equipped with a high voltagebattery. A cool battery maintains battery lifeand provides the best possible performance.The high voltage battery is cooled by cabinair drawn from vent holes in the trim panelsbehind the rear seats. Avoid placing objectsat the vent holes that block airflow to thehigh voltage battery.
Engine:
The engine speed in your hybrid is notdirectly tied to your vehicle speed. Yourvehicle's engine and transmission aredesigned to deliver the power you need atthe most efficient engine speed. Duringheavy accelerations, your hybrid may reachhigh engine speeds (up to 6000 RPM).
In prolonged mountainous driving, you maysee the engine speed changing without yourinput. This is intentional and maintains thebattery charge level. You may also noticeduring extended downhill driving that yourengine continues to run instead of shuttingoff.
During this engine braking, the engine stayson, but it is not using any fuel. You may alsohear a slight whine or whistle when operatingyour vehicle. This is the normal operation ofthe electric generator in the hybrid system.

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS
AnswerQuestion
The high voltage battery is electrically isolated from the rest of thevehicle when the key is off. When you switch the key on, high voltagecontactors inside the battery are closed to make the electricity avail-able to the motor and generator and enable the vehicle to drive. Theclicks are the sound of these contactors as they close and open duringstart up and shut down.
What are the series of clicks from the cargo area when I first turn thekey in the ignition?
The vehicle's computer will determine if an engine start is requiredat key-on. Silent key start will start the engine if it is necessary forcabin heating, windshield defrost, or if the outside temperature is low.(For C-MAX and Fusion Energi vehicles, the engine may not berequired to operate these functions.)
Why does the engine sometimes start at key-on?
There are several reasons the engine stays on for an extended amountof time when you first start it. One common reason is to make surethat the emissions components are warm enough to minimize tailpipeemissions. As the climate gets cooler, this engine-on time is extended.
Why does it take a long time before the engine shuts down?
The engine is required to turn on above this speed to protect thetransmission hardware.Why does my engine never shut down above 85 mph (137 km/h)

AnswerQuestion
In order to make sure that the climate control system can begin heatingthe cabin or defrosting the windshield as soon as a driver requestsit, the engine coolant temperature has to be kept sufficiently hot.Keeping the engine on is required to maintain the correct coolanttemperature.
Why does my engine stay on when it is extremely cold outside?
Your vehicle's engine and transmission are designed to deliver thepower you need at the most efficient engine speed. This may behigher than expected during heavy accelerations, and may fluctuatewhen driving at a steady speed. These are characteristics of theAtkinson engine cycle and the transmission technology that helpmaximize your hybrid's fuel economy.
Why does my engine rev up so high sometimes when I accelerate?
The fan noise comes from a fan located next to the high voltagebattery pack. This fan turns on when the battery requires cooling air.The fan speed, and associated noise level, will change according tothe amount of cooling required to maintain good performance. Main-taining the battery temperature at optimal conditions also prolongsthe 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 yearunder normal operating conditions.What is the engine oil change service interval?
Your hybrid vehicle can use E15 (15% ethanol, 85% gasoline) fuel, butyou may notice slightly reduced fuel economy because ethanolcontains less energy per gallon than gasoline. Your hybrid vehicle isnot designed to use E85 (85% ethanol).
Can I put E15 or E85 in my vehicle, and how will it affect my fueleconomy?

The scheduled maintenance items listed inscheduled maintenance information areessential to the life and performance of yourvehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for service ofcomponents affecting emission control, suchnon-Ford parts should be equivalent togenuine 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 damaged exhaustsystem may allow exhaust to enter thevehicle. Have a damaged or improperlyoperating exhaust system inspected andrepaired 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 vehicles arenot permitted to intentionally remove anemission control device or prevent it fromworking. Information about your vehicle’semission system is on the Vehicle EmissionControl Information Decal located on or nearthe engine. This decal also lists enginedisplacement.
Please consult your warranty information forcomplete 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 the environmentby making sure that your vehicle continuesto meet government emission standards. TheOBD-II system also assists a servicetechnician in properly servicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected a malfunction.Temporary malfunctions may cause theservice engine soon indicator to illuminate.Examples are:
1. Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in the fuel—theengine may misfire or run poorly.
3. The fuel fill inlet may not have closedproperly. See Refueling (page 182).
4. Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank with goodquality fuel, properly closing the fuel fill inletor letting the electrical system dry out. Afterthree driving cycles without these or anyother temporary malfunctions present, theservice engine soon indicator should stay offthe next time you start the engine. A drivingcycle consists of a cold engine startupfollowed by mixed city and highway driving.No additional vehicle service is required.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving brakingsystem, aftermarket roof racks,suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stability controlsystem. In addition, installing any stereoloudspeakers may interfere with andadversely affect the electronic stabilitycontrol system. Install any aftermarket stereoloudspeaker as far as possible from the frontcenter console, the tunnel, and the frontseats in order to minimize the risk ofinterfering with the electronic stability controlsensors. Reducing the effectiveness of theelectronic stability control system could leadto an increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
WARNINGS
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to lose controlof a vehicle due to inappropriate driver inputfor the conditions. Aggressive driving on anyroad condition can cause you to lose controlof your vehicle increasing the risk of personalinjury or property damage. Activation of theelectronic stability control system is anindication that at least some of the tires haveexceeded their ability to grip the road; thiscould reduce the operator’s ability to controlthe vehicle potentially resulting in a loss ofvehicle control, vehicle rollover, personalinjury and death. If your electronic stabilitycontrol system activates, SLOW DOWN.
The system automatically turns on each timeyou switch the ignition on.
If a fault occurs in either the stability controlor the traction control system, you mayexperience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and traction controlsystems do not enhance your vehicle'sability to maintain traction of the wheels.
If a driving condition activates either thestability control or the traction control systemyou may experience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe and yourfoot is not on the brake, the brake pedalmay move as the system applies higherbrake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
