2017 FORD C MAX ENERGI battery

Neutral:
It is not recommended to idle the vehiclein neutral (N) for an extended period oftime because this will discharge your highvoltage battery and decrease fueleconomy. The engine will not start or stop,and cannot provide power to the hybridsystem 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 enginebraking. This is normal and will not damageyour vehicle. In low gear, the gas enginewill remain 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 batterylife and provides the best possibleperformance. The high voltage battery iscooled by cabin air drawn from vent holesin the trim panels behind the rear seats.Avoid placing objects at the vent holes thatblock airflow to the high 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 withoutyour input. This is intentional and maintainsthe battery charge level. You may alsonotice during extended downhill drivingthat your engine continues to run insteadof shutting off.
During this engine braking, the engine stayson, but it is not using any fuel. You may alsohear a slight whine or whistle whenoperating your vehicle. This is the normaloperation of the electric generator in thehybrid system.
During certain events (such as vehicleservicing) your low voltage 12-volt batterymay become disconnected or disabled.Once the battery is reconnected and afterdriving the vehicle, the engine maycontinue to operate for three to fiveseconds after the key is turned to off. Thisis a normal condition.
Braking:
Your hybrid is equipped with standardhydraulic braking and regenerative braking.Regenerative braking is performed by yourtransmission and it captures brake energyand stores it in your high voltage battery.
Driving to Optimize Fuel Economy
Note:Having your engine running is notalways an indication of inefficiency. In somecases, it is actually more efficient thandriving in electric mode.
Your fuel economy should improvethroughout your hybrid's break-in period.As with any vehicle, your driving habits andaccessory usage can significantly impactyour fuel economy. For best results, keepin mind these tips:

•Keep the tires properly inflated andonly use the recommended size.
•Aggressive driving increases theamount of energy required to moveyour vehicle. In general, you canachieve better fuel economy with mildto moderate acceleration anddeceleration. Moderate braking isparticularly important since it allowsyou to maximize the energy capturedby the regenerative braking system.
Additional Tips:
•Do not carry extra loads.
•Be mindful of adding externalaccessories that may increaseaerodynamic drag.
•Observe posted speed limits.
•Perform all scheduled maintenance.
•There is no need to wait for your engineto warm up. The vehicle is ready todrive immediately after starting.
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.

Your vehicle may accelerate more slowlyand the top speed may be lower in EV Nowmode than in Auto EV mode.
You can enable your engine at any time byusing one of the following methods:
1.Press the OK button on the left 5–waysteering wheel control while viewingthe miles or kilometers per chargescreen. Your vehicle will enable theengine as needed, and willautomatically return to EV Now aftereight seconds or when the engine is nolonger needed.
2.Press the accelerator pedal fully. A popup message will appear. Press OK onthe left-hand steering wheel button toactivate as needed. The message willdisappear if you release the acceleratorpedal.
3. Press the EV button. This will changethe mode to EV Later and permitengine operation.
Your vehicle may automatically enterEngine Enabled mode if system conditionsrequire it. A engine enabled message willdisplay if this occurs. This is normalfunction, and your vehicle will return to EVNow when possible.
Your vehicle may enter Enable Enginemode if the climate control is in a defrostmode and the outside temperature is cold.A engine enabled message will display ifthis occurs. If defrost is not needed, selecta different climate control mode to permitEV Now.
When you enable EV Now, a blue EV icondisplays in the left-hand informationdisplay. If your vehicle is in the EngineEnabled mode, the EV icon will be yellow.
EV Now will automatically exit when thePlug in power has been depleted.
EV Later
This mode saves most of thehigh voltage battery plug inpower for future use (forexample, your initial drive is at high speedson open roads, but later your drive will beat low speeds in an urban area whereplug-in power usage is most efficient).Your vehicle will run the engine as neededand keep most of the high voltage batteryplug in power for later use in Auto Mode orEV Now mode.
When you enable EV Later, a white EVLater icon appears on the left-handinformation display.
The EV Later mode will automatically resetto EV Auto mode when you power yourvehicle off. You may press the EV buttontwice during the next drive to return to EVLater mode, if desired.
ECO Cruise
Note:ECO Cruise is available as a separatefeature on Energi vehicles only. On nonplug-in vehicles it is included in EcoSelect.
This feature saves vehicle energy byrelaxing acceleration compared tostandard cruise control. For example, yourvehicle may temporarily lose speed whengoing uphill. When set to on, ECO appearsin the information display when cruisecontrol is on.
You can switch it on or off in through theinformation display. See GeneralInformation (page 92).

HYBRID VEHICLE FREQUENTLY ASKED QUESTIONS
AnswerQuestion
The high voltage battery is electrically isol-ated from the rest of the vehicle when thekey is off. When you switch the key on, highvoltage contactors inside the battery areclosed to make the electricity available tothe motor and generator and enable thevehicle to drive. The clicks are the sound ofthese contactors as they close and openduring start up and shut down.
What are the series of clicks from the cargoarea when I first turn the key in the ignition?
The vehicle's computer will determine if anengine start is required at key-on. Silent keystart will start the engine if it is necessaryfor cabin heating, windshield defrost, or ifthe outside temperature is low. (For C-MAXEnergi vehicles, the engine may not berequired to operate these functions.)
Why does the engine sometimes start atkey-on?
There are several reasons the engine stayson for an extended amount of time whenyou first start it. One common reason is tomake sure that the emissions componentsare warm enough to minimize tailpipeemissions. As the climate gets cooler, thisengine-on time is extended.
Why does it take a long time before theengine shuts down?
The engine is required to turn on above thisspeed to protect the transmission hard-ware.
Why does my engine never shut downabove 85 mph (137 km/h)
In order to make sure that the climatecontrol system can begin heating the cabinor defrosting the windshield as soon as adriver requests it, the engine coolanttemperature 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 isextremely cold outside?

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?

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.
