HYBRID VEHICLE OPERATION
This hybrid vehicle combines electric andgasoline propulsion to providebreakthrough performance and improvedefficiency.
Familiarizing yourself with these uniquecharacteristics will provide an optimaldriving experience from your new vehicle.
Note:You may notice higher engine speedsupon start-up. This temporary condition isnormal and necessary to heat up the cabinand minimize emissions.
Starting:
When you start your vehicle, agreen ready indicator light willappear in the lower right portionof the instrument cluster and a ready todrive message will appear in the middle ofthe left cluster screen, letting you knowthat your vehicle is ready for driving.
The engine may not start because thisvehicle is equipped with silent key start.This fuel saving feature allows your vehicleto be ready–to–drive without requiring thegas engine to be running. This indicator willremain on while your vehicle is on, whetherthe engine is running or not to indicate yourvehicle is capable of movement (using itselectric motor, engine, or both). Typically,the engine will not start unless the vehicleis cold, a climate control change isrequested, or the accelerator is pressed.
Driving:
The gas engine automatically starts andstops to provide power when needed andto save fuel when not needed. Whilecoasting at low speeds, coming to a stop,or standing, the gas engine normally shutsdown and your vehicle operates inelectric-only mode.
Conditions that may cause the engine tostart up or remain running include:
•Considerable vehicle acceleration.
•Vehicle speed above 85 mph(137 km/h). However, the maximumspeed for electric-only operation maybe lower while driving in hottemperatures or on hilly terrain.
•Ascending a hill.
•Charge level of high voltage battery islow.
•Very high or low outside temperature(to provide system cooling or heating).For Energi vehicles, climate controldemands by passengers may notdirectly cause the engine to run. Thisonly occurs when the high voltagebattery charge is low, or if the outsidetemperature is cold enough to requirethe engine to provide additional heatfor the cabin.
•Engine not warm enough to providepassenger requested cabintemperature.
Stopping:
The gas engine may shut off to conservefuel as you come to a stop. Restarting yourvehicle is not required. Simply step on theaccelerator when you are ready to drive.
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:
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:

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 (page223).
Can I tow the hybrid behind my motor homewith all four wheels down?

FUEL QUALITY
Choosing the Right Fuel
We recommend regular unleaded gasolinewith a minimum pump (R+M)/2 octanerating of 87. Some fuel stations offer fuelsposted as regular unleaded gasoline withan octane rating below 87, particularly inhigh altitude areas. We do not recommendfuels with an octane rating below 87.
Do not use any fuel other than thoserecommended because they could lead toengine damage that may not be coveredby the vehicle Warranty.
Note:Use of any fuel other than thoserecommended can impair the emissioncontrol system and cause a loss of vehicleperformance.
Do not use:
•Diesel fuel.
•Fuels containing kerosene or paraffin.
•Fuel containing more than 15% ethanolor E85 fuel.
•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
Fuel Freshness Mode (If Equipped)
This helps keep the fuel system functionaland the fuel fresh.
If you mainly use your vehicle in electricpower mode without refueling, the gasolinein the fuel tank may become stale due toaging. Stale gasoline can damage theengine and fuel system.
Your vehicle automatically switches to fuelfreshness mode if you do not refuel yourvehicle with fresh fuel within an 18-monthperiod. Fuel freshness mode protects yourvehicle from potential engine and fuelsystem damage caused by using stale fuel.
Note:If you do not add new fuel during an18-month period, fuel freshness mode willuse fuel until approximately 1.2 gal (4.5 L)of fuel remains in the fuel tank.
During fuel freshness mode:
•The information display will indicatefuel freshness mode is active.
•The vehicle will only run in hybrid mode.EV Now mode will not be available.
•Most of the plug-in power will bestored until fuel freshness mode iscompleted.
Note:EV Now mode resumes when lessthan 1.2 gal (4.5 L) of fuel remains in the fueltank.

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.
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 156).
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.
