•Follow the recommended servicemaintenance intervals. See GeneralMaintenance Information (page 594).
•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 afrequently appearing LOW FUELPRESSURE message.
Use of biodiesel in concentrations greaterthan 20% can 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 couldresult in a lack of power or damage to fuelsystem components, including fuel pumpand fuel injector failures.
We recommend SAE 5W-40 oil for fuelswith greater than 5% biodiesel (B5). Formore information about oil changeintervals and other maintenance whenoperating on biodiesel. See SpecialOperating Conditions ScheduledMaintenance (page 603).
Look for a label on the fuel pump toconfirm the amount of biodiesel containedin diesel fuel. Ask the service stationattendant to confirm the biodiesel contentof diesel fuel, if you do not see a label onthe fuel pump.
If you plan to park or store your vehicle formore than 1 month, then you should emptyyour vehicle fuel tank of biodiesel fuel. Youshould fill the tank with a purepetroleum-based diesel fuel and run yourvehicle for a minimum of 30 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 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 and performanceimprover or an equivalent additive if thereis fuel gelling.
Do not use alcohol-based additives toimprove cetane quality, to prevent fuelgelling or any other use. The use of alcoholadditives could result in damage to the fuelinjectors and system.
Your Warranty may not cover repairsneeded to correct the effects of using anaftermarket product that does not meetour specifications in your fuel.

WHAT IS THE CATALYTIC
CONVERTER
The catalytic converter is part of yourvehicle's emissions system and filtersharmful pollutants from the exhaust gas.
CATALYTIC CONVERTER
PRECAUTIONS
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
To avoid damaging the catalytic converter:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 422).

The electronic torque overlay steeringsystem adds supplemental steering assistto the hydraulic gear when needed,dependent on vehicle conditions such asvehicle speed, steering wheel angle, andsteering wheel torque. The hydraulicsteering system provides the majority ofsteering assistance. The electronic torqueoverlay enables features such as pro trailerbackup assistance and lane departurewarning.
If your vehicle loses electrical power whileyou are driving, your vehicle loses electricpower steering assistance. The steeringsystem still operates, and you can steeryour vehicle with hydraulic assist. Steeringyour vehicle with only hydraulic assistrequires 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.
LOCATING THE HYDRAULICPOWER STEERING FLUIDRESERVOIR
The hydraulic power steering fluid reservoiris found in the engine compartment. SeeUnder Hood Overview (page 441).
CHECKING THE HYDRAULICPOWER STEERING FLUID
Check the power steering fluid. SeeScheduled Maintenance (page 591). Ifadding fluid is necessary, use onlyMERCON LV ATF.
Check the fluid level when it is at ambienttemperature.
1.Check the fluid level in the reservoir. Itshould be between the MIN and MAXrange. Do not add fluid if the level iswithin this range.
2.If the fluid level is low, add fluid to bringthe fluid level up to between the MINand MAX range.
3.Switch the engine on.
4.While the engine idles, turn the steeringwheel left and right several times.
5.Switch the engine off.
6.Recheck the fluid level in the reservoir.Do not add fluid if the level is betweenthe MIN and MAX range.
7.If the fluid is low, add fluid in smallamounts, continuously checking thelevel until it is between the MIN andMAX range. For proper fluid type, SeeCapacities and Specifications (page520). Be sure to put the cap back on thereservoir.
