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.
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?

AnswerQuestion
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?
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 10,000 mi(16,000 km) or once per year under normaloperating 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?

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. Thepressure in an overfilled tank maycause leakage and lead to fuel sprayand fire.
The fuel system may be underpressure. If you hear a hissing soundnear the fuel filler inlet, do not refueluntil the sound stops. Otherwise, fuel mayspray out, which could cause seriouspersonal injury.
Fuels can cause serious injury ordeath if misused or mishandled.
Fuel may contain benzene, which isa cancer-causing agent.
When refueling always shut theengine off and never allow sparks oropen flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
Follow these guidelines when refueling:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Always switch the engine off beforerefueling.
•Automotive fuels can be harmful orfatal if swallowed. Fuel is highly toxicand if swallowed can cause death orpermanent injury. If fuel is swallowedimmediately call a physician, even if nosymptoms are immediately apparent.The toxic effects of fuel may not beapparent for hours.
•Avoid inhaling fuel vapors. Inhaling fuelvapor can lead to eye and respiratorytract irritation. In severe cases,excessive or prolonged breathing offuel vapor can cause serious illness andpermanent injury.
•Avoid getting fuel in your eyes. If yousplash fuel in your eyes, immediatelyremove contact lenses (if worn), flushwith water for 15 minutes and seekmedical attention. Failure to seekproper medical attention could lead topermanent injury.
•Fuels can be harmful if absorbedthrough the skin. If you splash fuel onyour skin, clothing or both, promptlyremove contaminated clothing andthoroughly wash your skin with soapand water. Repeated or prolonged skincontact causes skin irritation.
•Be particularly careful if you are takingAntabuse or other forms of Disulfiramfor the treatment of alcoholism.Breathing fuel vapors could cause anadverse reaction, serious personalinjury or sickness. Immediately call aphysician if you experience any adversereactions.
FUEL QUALITY
Choosing the Right Fuel
Your vehicle is designed to operate onregular unleaded gasoline with a minimumpump (R+M)/2 octane rating of 87.
157
Fusion Energi / Fusion Hybrid (CC7) Hybrid Electric Vehicle (HEV)/Plug-In Hybrid Electric Vehicle (PHEV), Canada/United States of America, enUSA, Edition date: 201705, Second Printing
Fuel and RefuelingE161513

Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. We do not recommendthese fuels.
For best overall vehicle and engineperformance, premium fuel with an octanerating of 91 or higher is recommended. Theperformance gained by using premium fuelis most noticeable in hot weather.
Do not use any fuel other than thoserecommended because they could lead toengine damage that will not be covered bythe 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.
Note:When the fuel level is less thanone-quarter full, refueling your vehicle willend fuel freshness mode.
Note:We recommend you use a fuelstabilizer if you use less than a full tank offuel during an 18-month period.
