Operation in Standing Water
Ingestion of water into the diesel enginecan result in immediate and severedamage to the engine. If driving throughwater, slow down to avoid splashing waterinto the intake. If the engine stalls, and yoususpect ingestion of water into the engine,do not try to restart the engine. Consultyour dealer for service immediately.
Your fuel tank vents to the atmosphere byvalves on top of the tank and through thefuel cap. If water reaches the top of thetank, the valves may pull water into thefuel tank. Water in the fuel can causeperformance issues and damage the fuelinjection system.
DIESEL PARTICULATE FILTER
The filter forms part of the emissionsreduction system on your vehicle. It filtersharmful diesel particulates (soot) from theexhaust gas.
Regeneration
WARNING
Do not park or idle your vehicle overdry leaves, dry grass or othercombustible materials. Theregeneration process creates very highexhaust gas temperatures and the exhaustwill radiate a considerable amount of heatduring and after regeneration and after youhave switched the engine off. This is apotential fire hazard.
Note:Avoid running out of fuel.
Note:During regeneration at low speed orengine idle, you may smell a hot metallicodor and could notice a clicking metallicsound. This is due to the high temperaturesreached during regeneration and is normal.
Note:Changes in the engine or exhaustsound may be heard during the regenerationprocess.
The diesel particulate filter on your vehiclerequires periodic regeneration to maintainits correct function. Your vehicle will carryout this process automatically.
If your journeys meet one of the followingconditions:
•You drive only short distances.
•You frequently switch the ignition onand off.
•Your journeys contain a high level ofacceleration and deceleration.
You must carry out occasional trips withthe following conditions to assist theregeneration process:
•Drive your vehicle in more favorableconditions, which you will find at highervehicle speeds in normal driving, on amain road or freeway for a minimumof 20 minutes. This drive may includeshort stops that will not affect theregeneration process.
•Avoid prolonged idling and alwaysobserve speed limits and roadconditions.
•Do not switch the ignition off.
•Select a suitable gear to ideallymaintain engine speed between 1500and 3000 RPM.

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.

Vehicles with engines configured for usewith high sulfur diesel fuel are onlyavailable for sale in countries where ultralow sulfur diesel fuel is generally notavailable or mandated by the government.Vehicles originally sold in a ultra low sulfurdiesel fuel market that are subsequentlyexported to non- ultra low sulfur diesel fuelmarkets will need to be retrofitted (at thecustomer’s expense using Ford authorizeddealer service parts) in order to be reliablyoperated on non- ultra low sulfur dieselfuel.
Biodiesel
WARNINGS
Do not use home heating oil,agricultural fuel, raw fats and oils,waste cooking greases, biodieselfuels greater than 20% or any diesel fuelnot intended for highway use. Damage tothe fuel injection system, engine andexhaust catalyst can occur if an improperfuel is used. Do not add gasoline, gasoholor alcohol to diesel fuel. This practicecreates a serious fire hazard and engineperformance problems.
Do not mix diesel fuel with gasoline,gasohol or alcohol. This could causean explosion resulting in personalinjury.
Do not add gasoline, gasohol oralcohol to diesel fuel. This practicecreates a serious fire hazard resultingin personal injury and engine performanceproblems.
Do not use home heating oil or anydiesel fuel not intended for highwayuse. Damage to the fuel injectionsystem, engine, exhaust catalyst and dieselparticulate filter can occur if an improperfuel is used. Red dye is used to identifyfuels intended for agricultural andnon-highway use.
You may operate your vehicle on dieselfuels containing up to 20% biodiesel, alsoknown as B20.
Biodiesel fuel is a chemically convertedproduct from renewable fuel sources, suchas vegetable oils, animal fats and wastecooking greases.
To help achieve acceptable engineperformance and durability when usingbiodiesel in your vehicle:
•Confirm the biodiesel content of thefuel to be B20 (20% biodiesel) or less
•Only use biodiesel fuel of good qualitythat complies with industry standards
•Follow the recommended servicemaintenance intervals. SeeScheduled Maintenance (page 573).
•Do not store biodiesel fuel in the fueltank for more than 1 month
•Consider changing brands or reducingbiodiesel content if you have coldtemperature fuel gelling issues or afrequent LOW FUEL PRESSUREmessage appearing
•Do NOT use raw oils, fats or wastecooking greases
Use of biodiesel in concentrations greaterthan 20% may cause damage to yourvehicle, including engine and/or exhaustafter-treatment hardware (exhaustcatalyst and particulate filter) failures.Concentrations greater than 20% can alsocause fuel filter restrictions that may resultin a lack of power or damage to fuelsystem components, including fuel pumpand fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil isrecommended for fuels with greater than5% biodiesel (B5). Refer to the Specialoperating conditions section under theSchedule Maintenance chapter for moreinformation about oil change intervals andother maintenance when operating onbiodiesel.
