2018 FORD FUSION ENERGI service

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?

CATALYTIC CONVERTER
WARNINGS
Do not park, idle or drive your vehicleon dry grass or other dry groundcover. The emission system heats upthe engine compartment and exhaustsystem, creating the risk of fire.
The normal operating temperatureof the exhaust system is very high.Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a short periodof engine operation and stays hot after theengine is switched off.
WARNINGS
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 233).
•Use only the specified fuel listed.
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Resulting component damage maynot be covered by the vehicle Warranty.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.

Engine Emission Control

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 160).
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.

Engine Emission Control

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.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 278).
See Warning Lamps andIndicators (page 92).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Switch the engine off, move thetransmission to park (P) and apply theparking brake. Inspect the acceleratorpedal and the area around it for any itemsor debris that may be obstructing itsmovement.If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate atwhich you press the brake pedal. Itprovides maximum braking efficiency aslong as you press the pedal. Emergencybrake assist can reduce stopping distancesin critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the anti-lock braking system maybe disabled. Have the system checked byan authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.
If the brake warning lampilluminates with the parkingbrake released, have your brakesystem serviced immediately.
It also illuminates momentarily when youswitch the ignition on to confirm the lampis functional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the system checkedby an authorized dealer.
HINTS ON DRIVING WITH
