CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and childsafety seat systems periodically to makesure they work properly and are notdamaged. Inspect the vehicle and childrestraint seatbelts to make sure there areno nicks, tears or cuts. Replace ifnecessary. All vehicle seatbelt assemblies,including retractors, buckles, front seatbeltbuckle assemblies, buckle supportassemblies (slide bar-if equipped),shoulder belt height adjusters (ifequipped), shoulder belt guide on seatbackrest (if equipped), child safety seatLATCH and tether anchors, and attachinghardware, should be inspected after acrash. Read the child restraintmanufacturer's instructions for additionalinspection and maintenance informationspecific to the child restraint.
We recommend that all seatbeltassemblies in use in vehicles involved in acrash be replaced. However, if the crashwas minor and an authorized dealer findsthat the belts do not show damage andcontinue to operate properly, they do notneed to be replaced. Seatbelt assembliesnot in use during a crash should also beinspected and replaced if either damageor improper operation is noted.
Properly care for seatbelts. See VehicleCare (page 262).

personal injury or sickness may result.If you splash fuel on your skin, promptlywash your skin thoroughly with soapand water. Consult a physicianimmediately if you experience anadverse reaction.
Low Fuel Pressure (If Equipped)
Diesel engine vehicles have a low fuelpressure detection system.
The following are possible causes for a lowfuel pressure warning message to appearin the information display:
•Cold start or during cold operationbelow 32°F (0°C). If the low fuelpressure message appears during acold start or up to 10 minutes after theinitial cold start, monitor theinformation display. If the low fuelpressure message disappears and doesnot re-appear after the engine has fullywarmed up, waxed or gelled fuel iswhat most likely caused the message.Do not use alcohol based additives tocorrect fuel gelling. This may result indamage to the fuel injectors andsystems. Use an anti-gel additive. SeeFuel Quality (page 108).
Note:The vehicle Warranty may be void ifyou use additives that do not meet orexceed Ford specifications. If the low fuelpressure message persistently appears afterre-fueling and then disappears when theengine has fully warmed up, consider usingdifferent fuel sources.
•Low fuel operation: If the low fuelpressure message appears when yourvehicle is warm and during low fueltank level operation (near empty),refuel your vehicle. If the messagereappears after fueling, see below. Ifthe message does not come back, thelow fuel pressure condition was due tolow fuel levels in the fuel tank.
•Normal operation: If the low fuelpressure message appears duringnormal operation when the engine isfully warm, and fuel level is not low,you must change the fuel filtersregardless of the maintenanceschedule interval.
•If replacement of the fuel filter doesnot remedy the low fuel pressuremessage during normal operation asdefined above, take the vehicle to anauthorized dealer.
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.

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 325).
•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.
Look for a label on the fuel pump toconfirm the amount of biodiesel containedin a diesel fuel. Biodiesel content is oftenindicated with the letter B followed by thepercent of biodiesel in the fuel. Forexample, B20 indicates a fuel containing20% biodiesel. Ask the service stationattendant to confirm the biodiesel contentof a diesel fuel if you do not see a label onthe fuel pump.
Biodiesel fuels degrade more easily thandiesel fuels not containing biodiesel andshould not be stored in the fuel tank formore than 1 month. If you plan to park orstore your vehicle for more than 1 month,then you should empty your vehicle fueltank of biodiesel fuel. You should fill thetank with a pure petroleum-based dieselfuel and run your vehicle for a minimum of30 minutes.
Note:Degraded or oxidized biodiesel candamage fuel system seals and plastics andcorrode steel parts.
During cold weather, if you have problemsoperating on biodiesel, you may need touse a diesel fuel with lower biodieselcontent, try another brand, or discontinuethe use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add anyaftermarket additives to your fuel if youuse a high quality diesel fuel that conformsto ASTM industry specifications.Aftermarket additives can damage the fuelinjector system or engine.
Use Motorcraft® cetane booster or anequivalent cetane booster additive if yoususpect fuel has low cetane. UseMotorcraft® anti-gel & performanceimprover or an equivalent additive if thereis fuel gelling.
