2017 FORD FUSION HYBRID maintenance

WARNINGS
Do not put engine coolant in thewindshield washer fluid container. Ifsprayed on the windshield, enginecoolant could make it difficult to seethrough the windshield.
To reduce the risk of personal injury,make sure the engine is cool beforeunscrewing the coolant pressurerelief cap. The cooling system is underpressure. Steam and hot liquid can comeout forcefully when you loosen the capslightly.
Do not add coolant further than theMAX mark.
Your vehicle has two separate coolingsystems. One for cooling the engine and aseparate system for cooling the invertersystem controller that is specific to thehybrid operating system. The two systemsoperate similarly, with the inverter systemcontroller cooling system generallyoperating at a lower temperature andpressure.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 466).
Note:Make sure that the coolant level isbetween the MIN and MAX marks on thecoolant 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
WARNING
Never remove the coolant reservoircap while the engine is running or hot.
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 310). 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: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 (page306).

Maintenance

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.
Note:If prediluted coolant is not available,use the approved antifreeze concentratediluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 306).Using water that has not been deionisedmay contribute to deposit formation,corrosion or plugging of the small coolingsystem passageways.
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.
Note:In case of emergency, you can add alarge amount of water without coolant inorder to reach a vehicle service location.Water alone, without coolant, can causeengine damage from corrosion, overheatingor freezing. When you reach a servicelocation, you must have the cooling systemdrained, flushed and refilled using thecorrect specification prediluted coolant orantifreeze concentrate. See Capacities andSpecifications (page 306).
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.
258

Maintenance

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.
Coolant Change
At specific mileage intervals, as listed inthe scheduled maintenance information,the coolant should be changed. Addprediluted coolant approved to the correctspecification. See Capacities andSpecifications (page 306).
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, thecoolant temperature gauge moves towardthe red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNINGS
Fail-safe mode is for use duringemergencies only. Operate yourvehicle in fail-safe mode only as longas necessary to bring your vehicle to restin a safe location and seek immediaterepairs. When in fail-safe mode, yourvehicle will have limited power, will not beable to maintain high-speed operation, andmay completely shut down withoutwarning, potentially losing engine power,power steering assist, and power brakeassist, which may increase the possibilityof a crash resulting in serious injury.
Never remove the coolant reservoircap while the engine is running or hot.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofautomatically shutting down to preventengine damage. In this situation:
1. Pull off the road as soon as safelypossible and switch the engine off.

2. If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3. If this is not possible, wait a shortperiod for the engine to cool.
4. Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5. When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note:Driving your vehicle without repairincreases the chance of engine damage.
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 higher atemperature 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.In order 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. Afterseveral minutes, if the temperaturedoes not drop, 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.
The automatic transmission does not havea transmission fluid dipstick.
Have an authorized dealer check andchange the transmission fluid at thecorrect service interval. Your transmissiondoes not consume fluid. However, the fluidlevel should be checked if the transmissionis not working properly, (i.e., if thetransmission slips or shifts slowly) or if younotice some sign of fluid leakage.
Do not use supplemental transmissionfluid additives, treatments or cleaningagents. The use of these materials mayaffect transmission operation and resultin damage to internal transmissioncomponents.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAXlines are within the normal operating range;there is no need to add fluid. If the fluidlevels are outside of the normal operatingrange, the performance of the systemcould be compromised; seek service fromyour authorized dealer immediately.
WASHER FLUID CHECK
WARNING
If you operate your vehicle intemperatures below 40°F (5°C), usewasher fluid with antifreezeprotection. Failure to use washer fluid withantifreeze protection in cold weather couldresult in impaired windshield vision andincrease the risk of injury or accident.
Add fluid to fill the reservoir if the level islow. Only use a washer fluid that meetsFord specifications. See Capacities andSpecifications (page 306).
State or local regulations on volatileorganic compounds may restrict the useof methanol, a common windshield washerantifreeze additive. Washer fluidscontaining non-methanol antifreezeagents should be used only if they providecold weather protection without damagingthe vehicle’s paint finish, wiper blades orwasher system.
CHANGING THE 12V BATTERY
WARNINGS
Batteries normally produce explosivegases which can cause personalinjury. Therefore, do not allowflames, sparks or lighted substances tocome near the battery. When working nearthe battery, always shield your face andprotect your eyes. Always provide correctventilation.
When lifting a plastic-cased battery,excessive pressure on the end wallscould cause acid to flow through thevent caps, resulting in personal injury anddamage to the vehicle or battery. Lift thebattery with a battery carrier or with yourhands on opposite corners.
Keep batteries out of reach ofchildren. Batteries contain sulfuricacid. Avoid contact with skin, eyes orclothing. Shield your eyes when workingnear the battery to protect against possiblesplashing of acid solution.

The 12V battery is located in the left-handside of the luggage compartment. Removethe door to gain access to the battery.
Your vehicle is fitted with a Motorcraftmaintenance-free battery which normallydoes not require additional water.
Note:After cleaning or replacing thebattery, make sure you reinstall the batterycover or shield.
When a battery replacement is required,you must use a recommendedreplacement battery that matches theelectrical requirements of the vehicle.
Note:Contact an authorized dealer for lowvoltage battery access, testing orreplacement.
To make sure the battery managementsystem works correctly, do not connect anelectrical device ground connectiondirectly to the low voltage battery negativepost. This can cause inaccuratemeasurements of the battery conditionand potential incorrect system operation.
Note:If you add electrical accessories orcomponents to the vehicle, it may adverselyaffect the low voltage battery performanceand durability. This may also affect theperformance of other electrical systems inthe vehicle.
For longer, trouble-free operation, keep thetop of the battery clean and dry.
If you see any corrosion on the battery orterminals, remove the cables from theterminals and clean with a wire brush. Youcan neutralize the acid with a solution ofbaking soda and water.
Because your vehicle’s engine iselectronically-controlled by a computer,some engine control settings aremaintained by power from the low-voltagebattery. Some engine computer settings,like the idle trim and fuel trim strategy,optimize the driveability and performanceof the engine. The clock and radio stationpresets are also maintained in memory bypower from the low-voltage battery. Thesesettings are erased when a techniciandisconnects and connects the low-voltagebattery.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start yourvehicle.
5. Run the engine until it reaches normaloperating temperature. While theengine is warming up, complete thefollowing: Reset the clock. See AudioSystem (page 314).
