2018 FORD FUSION ENERGI heating

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).
•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:
We recommend that you do not idle thevehicle in neutral (N) for an extendedperiod of time because this will dischargeyour high voltage battery, shut off your airconditioning and heating, and decreasefuel economy. The engine will not start orstop, and cannot provide power to thehybrid system in neutral (N).

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?

Unique Driving Characteristics

Overriding the Set Speed
WARNING
If you override the system by pressingthe accelerator pedal, it does notautomatically apply the brakes tomaintain a gap from any vehicle ahead.
When you press the accelerator pedal, youoverride the set speed and gap distance.
When you override the system,the green indicator lightilluminates and the vehicleimage does not appear in the informationdisplay.
The system resumes operation when yourelease the accelerator pedal. The vehiclespeed decreases to the set speed, or alower speed if following a slower vehicle.
Changing the Set Speed
•Press RES+ or SET- to change the setspeed in small increments.
•Press the accelerator or brake pedaluntil you reach the desired speed. PressRES+ or SET-.
•Press and hold RES+ or SET- tochange the set speed in largeincrements. Release the control whenyou reach the desired speed.
The system may apply the brakes to slowthe vehicle to the new set speed. The setspeed displays continuously in theinformation display when the system isactive.
Canceling the Set Speed
Press CNCL or tap the brake pedal. Theset speed does not erase.
Resuming the Set Speed
Note:Only use resume if you are aware ofthe set speed and intend to return to it.
Press RES+. Your vehicle speed returns tothe previously set speed and gap setting.The set speed displays continuously in theinformation display when the system isactive.
Automatic Cancellation
Automatic cancellation can also occur if:
•The tires lose traction.
•You apply the parking brake.
Hilly Condition Usage
Note:An audible alarm sounds and thesystem shuts down if it applies brakes foran extended period of time. This allows thebrakes to cool. The system functionsnormally again after the brakes cool.
Select a lower gear when the system isactive in situations such as prolongeddownhill driving on steep grades, forexample in mountainous areas. Thesystem needs additional engine braking inthese situations to reduce the load on thevehicle’s regular brake system to preventit from overheating.
Switching Adaptive Cruise ControlOff
Note:You erase the set speed and gapsetting when you switch the system off.
Press OFF when the system is in standbymode, or switch the ignition off.
Detection Issues
WARNINGS
On rare occasions, detection issuescan occur due to the roadinfrastructures, for example bridges,tunnels and safety barriers. In these cases,the system may brake late orunexpectedly. At all times, you areresponsible for controlling your vehicle,supervising the system and intervening, ifrequired.

Note:The system may not correctly operatewhen towing a trailer. For vehicles with atrailer tow module and tow bar approvedby us, the system turns off when you attacha trailer. For vehicles with an aftermarkettrailer tow module or tow bar, werecommend that you switch the system offwhen you attach a trailer.
To permanently switch the system off,contact an authorized dealer.
STEERING
Electric Power Steering
WARNINGS
The electric power steering systemhas diagnostic checks thatcontinuously monitor the system. Ifa fault is detected, a message displays inthe information display. Stop your vehicleas soon as it is safe to do so. Switch theignition off. After at least 10 seconds,switch the ignition on and watch theinformation display for a steering systemwarning message. If a steering systemwarning message returns, have the systemchecked by an authorized dealer.
If the system detects an error, youmay not feel a difference in thesteering, however a serious conditionmay exist. Obtain immediate service froman authorized dealer, failure to do so mayresult in loss of steering control.
Your vehicle has an electric power steeringsystem. There is no fluid reservoir. Nomaintenance is required.
If your vehicle loses electrical power whileyou are driving, electric power steeringassistance is lost. The steering system stilloperates and you can steer your vehiclemanually. Manually steering your vehiclerequires more effort.
Extreme continuous steering may increasethe effort required for you to steer yourvehicle. This increased effort preventsoverheating and permanent damage tothe steering system. You do not lose theability to steer your vehicle manually.Typical steering and driving maneuversallow the system to cool and return tonormal operation.
Steering Tips
If the steering wanders or pulls, check for:
•Correct tire pressures.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
Adaptive Learning
The electronic power steering systemadaptive learning helps correct roadirregularities and improves overall handlingand steering feel. It communicates withthe brake system to help operateadvanced stability control and accidentavoidance systems. Additionally, wheneverthe battery is disconnected or a newbattery installed, you must drive yourvehicle a short distance before the systemrelearns the strategy and reactivates allsystems.

Driving Aids

Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -30°F (-34°C) and -34°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNINGS
Do not add engine coolant when theengine is hot. Failure to follow thisinstruction could result in personalinjury.
Never remove the coolant reservoircap when the engine is running orhot.
Note: Automotive fluids are notinterchangeable. Do not use coolant orwindshield washer fluid outside of itsspecified function and vehicle location.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 312). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 308).Using water that has not been deionizedmay contribute to deposit formation,corrosion and plugging of the small coolingsystem passageways.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
To top up the coolant level do thefollowing:
1. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2. Add prediluted coolant approved tothe correct specification. SeeCapacities and Specifications (page308).
3. Add enough prediluted coolant toreach the correct level.
4.Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.

5. Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the correct level.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.In this instance, qualified personnel:
1. Must drain the cooling system.
2. Chemically clean the cooling system.
3. Refill with prediluted coolant as soonas possible.
Water alone, without coolant, can causeengine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Recycled Coolant
We do not recommend the use of recycledcoolant as an approved recycling processis not yet available.
Dispose of used engine coolant in anappropriate manner. Follow yourcommunity's regulations and standardsfor recycling and disposing of automotivefluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to increase thecoolant concentration above 50%.
•A coolant concentration of 60%provides improved freeze pointprotection. Coolant concentrationsabove 60% decrease the overheatprotection characteristics of thecoolant and may cause enginedamage.
If you drive in extremely hot climates:
•You can decrease the coolantconcentration to 40%.
•Coolant concentrations below 40%decrease the freeze and corrosionprotection characteristics of thecoolant and may cause enginedamage.
Vehicles driven year-round in non-extremeclimates should use prediluted coolant foroptimum cooling system and engineprotection.

Engine Coolant TemperatureManagement (If Equipped)
WARNING
To reduce the risk of crash and injury,be prepared that the vehicle speedmay reduce and the vehicle may notbe able to accelerate with full power untilthe coolant temperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
At this time, you may notice the coolanttemperature gauge moves toward the redzone and a message may appear in theinformation display.
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is no needto pull off the road. You can continue todrive your vehicle.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1. Pull off the road as soon as safelypossible and shift the transmission intopark (P).
2. Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4. If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5. If the coolant level is normal, restartthe engine and continue.
AUTOMATIC TRANSMISSION
FLUID CHECK
Note:Transmission fluid should be checkedby an authorized dealer. If required, fluidshould be added by an authorized dealer.
Have an authorized dealer check andchange the transmission fluid at thecorrect service interval. See ScheduledMaintenance (page 473). Yourtransmission does not consume fluid.However, the fluid level should be checkedif the transmission is not working properly,(i.e., if the transmission slips or shiftsslowly) or if you notice some sign of fluidleakage.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
