Switching Between E85 andGasoline
We do not recommend repeatedlyalternating between E85 and gasoline. Ifyou switch from using E85 to gasoline, orfrom gasoline to E85, add as much fuel aspossible, at least half a tank. Drive yourvehicle immediately for a minimum of 5 mi(8 km) to allow it to adapt to the changein ethanol concentration. If you use E85exclusively, we recommend that you fillthe fuel tank with regular unleadedgasoline at each scheduled oil change.
FUEL QUALITY - DIESEL
Fuel Requirements - Choosing TheRight Fuel: Vehicles OperatedWhere Ultra Low Sulfur Diesel FuelIs Required (UnitedStates/Canada/Puerto Rico/U.S.Virgin Islands And Other Locales)
You should use Ultra-Low Sulfur Dieselfuel (also known as ULSD) designated asnumber 1-D or 2-D with a maximum of15-ppm sulfur in your diesel vehicle. Youmay operate your vehicle on diesel fuelscontaining up to 20% biodiesel, alsoknown as B20. These fuels should meetthe ASTM D975 diesel or the ASTM D7467B6-B20 biodiesel industry specifications.Outside of North America, use fuelsmeeting EN590 or equivalent local marketstandard.
Note:The vehicle Warranty does not coverdamage caused by using an improper typeof fuel or fuel additive.
Note:Do not blend used engine oil withdiesel fuel under any circumstances.Blending used oil with the fuel willsignificantly increase your vehicle’s exhaustemissions and reduce engine life due toincreased internal wear.
Using low sulfur diesel fuel(16-500 ppm) or high sulfurdiesel fuel (greater than 500ppm) in your diesel engine will causecertain emission components tomalfunction which may also cause theservice engine soon light to illuminateindicating an emissions-related concern.
Diesel fuel is adjusted seasonally for coldtemperature. For best results attemperatures below 19°F (-7°C), it isrecommended to use a diesel fuel whichhas been seasonally adjusted for theambient conditions.
Fuel Requirements - Choosing TheRight Fuel: Vehicles OperatedWhere Ultra Low Sulfur Diesel FuelIs Not Required
For the engine to operate reliably onlow-sulfur or high-sulfur diesel fuel, theengine must be a factory built high-sulfurengine (available as a dealer order optionfor select markets) or an ultra low sulfurdiesel fuel configured engine that has beenretrofitted for high-sulfur diesel fuel usingFord Motor Company dealer service parts.Failure to use retrofit components otherthan those available through yourauthorized dealer will result in coolantsystem damage, engine overheating,selective catalyst reduction system ordiesel particulate filter damage andpossible base engine damage.
Use only a diesel engine configured for usewith high sulfur diesel fuel in markets withdiesel fuel that has sulfur content greaterthan 15 ppm. Using low sulfur diesel fuel(16–500 ppm) or high sulfur diesel fuel(greater than 500 ppm) in a diesel enginedesigned to use only Ultra Low SulfurDiesel fuel may result in damage to engineemission control devices and theaftertreatment system, potentiallyrendering the vehicle inoperable.

ENGINE COOLANT CHECK -
6.2L/6.8L
WARNINGS
Do not add engine coolant when theengine is hot. Steam and scaldingliquids released from a hot coolingsystem can burn you badly. Also, spillingcoolant on hot engine parts can burn you.
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.
WARNINGS
Do not add coolant further than theMAX mark.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 573).
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. Werecommend, Robinair® Coolant andBattery Refractometer 75240 (Rotundatool part number: ROB75240). We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
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.

Maintenance

It is very important to use predilutedcoolant meeting the correct specificationin order to avoid plugging the smallpassageways in the engine cooling system.See Capacities and Specifications(page 422). Incorrect prediluted coolantuse can cause damage not covered by thevehicle Warranty.
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 meeting thecorrect specification. See Capacitiesand Specifications (page 415).
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.
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.
Do not mix different colors or types ofprediluted coolant in your vehicle. Mixingof prediluted coolant or using an incorrectprediluted coolant may harm the engineor cooling system components and maynot be covered by the vehicle Warranty.
In case of emergency, you can add a largeamount of water without predilutedcoolant in order to reach a vehicle servicelocation. On arrival do the following:
1. Drain the cooling system.
2. Chemically clean the cooling system.We recommend Motorcraft PremiumCooling System Flush.
3. Refill with prediluted coolant as soonas possible.
Water alone, without prediluted coolant,can cause engine 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.

Maintenance

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:
•It may be necessary to decrease thecoolant concentration to 40%.
•A coolant concentration of 40%provides improved overheat protection.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.
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:

Maintenance

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.

For vehicles with overflow coolant systemswith a non-pressurized cap on the coolantrecovery system, add coolant to thecoolant recovery reservoir when the engineis cool. Add prediluted coolant to themaximum level. For all vehicles which havea coolant degas system with a pressurizedcap, or if it is necessary to remove thecoolant pressure relief cap on the radiator,follow these steps to add engine coolant:
1. Turn the engine off and let it cool.
2. Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
3. Fill the coolant reservoir slowly withprediluted engine coolant to within theminimum and maximum range on theengine coolant reservoir. If youremoved the radiator cap in anoverflow system, fill the radiator untilthe coolant is visible and the radiatoris almost full. If coolant is added tobring the level within the minimum andmaximum range when the engine is notcold, the system may remain underfilled.
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 proper level.
Note:If prediluted coolant is not available,use the approved antifreeze concentratediluting it to 50/50 with distilled water. SeeCapacities and Specifications (page 427).Using water that has not been deionizedmay 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 427).
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 non-specifiedadditives to the coolant. These can beharmful and compromise the corrosionprotection of the coolant.
