HOW DOES THE ENGINE BLOCKHEATER WORK
The engine block heater warms the enginecoolant. This allows the climate controlsystem to quickly respond. The equipmentincludes a heater element installed in theengine block and a wire harness. You canconnect the system to a grounded 110 voltAC electrical source.
Note:The engine block heater is mosteffective when outdoor temperatures arebelow 0°F (-18°C). We recommend the useof engine block heater to improve enginecold start performance.
USING THE ENGINE BLOCKHEATER
Make sure the receptacle terminals areclean and dry prior to use. Clean them witha dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hoursof energy per hour of use. The system doesnot have a thermostat. It achievesmaximum temperature afterapproximately three hours of operation.Using the engine block heater longer thanthree hours does not improve systemperformance and unnecessarily useselectricity.

FUEL AND REFUELING
PRECAUTIONS
WARNING: Fuels can cause seriousinjury or death if misused or mishandled.
WARNING: Fuel may containbenzene, which is a cancer-causingagent.
Follow these guidelines when refueling:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Switch the engine off before refueling.
•Automotive fuels can be harmful orfatal if swallowed. Fuel is highly toxicand if swallowed can cause death orpermanent injury. If fuel is swallowedimmediately call a physician, even if nosymptoms are immediately apparent.The toxic effects of fuel may not beapparent for hours.
•Avoid inhaling fuel vapors. Inhaling fuelvapor can lead to eye and respiratorytract irritation. In severe cases,excessive or prolonged breathing offuel vapor can cause serious illness andpermanent injury.
•Avoid getting fuel in your eyes. If yousplash fuel in your eyes, immediatelyremove contact lenses, if worn, flushwith water for 15 minutes and seekmedical attention. Failure to seekproper medical attention could lead topermanent injury.
•Fuels can be harmful if absorbedthrough the skin. If you splash fuel onyour skin, clothing or both, promptlyremove contaminated clothing andthoroughly wash your skin with soapand water. Repeated or prolonged skincontact causes skin irritation.
•Be particularly careful if you are takingAntabuse or other forms of Disulfiramfor the treatment of alcoholism.Breathing fuel vapors could cause anadverse reaction, serious personalinjury or sickness. Immediately call aphysician if you experience any adversereactions.
FUEL QUALITY
SELECTING THE CORRECT FUEL -GASOLINE
Your vehicle operates on regular unleadedgasoline with a minimum pump (R+M)/2octane rating of 87.
Some fuel stations, particularly those inhigh altitude areas, offer fuels posted asregular unleaded gasoline with an octanerating below 87. The use of these fuelscould result in engine damage that will notbe covered by the vehicle Warranty.

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 could 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), werecommend using a diesel fuel which hasbeen seasonally adjusted for the ambientconditions.
Choosing the Right Fuel: VehiclesOperated Where Ultra Low SulfurDiesel Fuel Is 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 usingauthorized dealer service parts. Failure touse retrofit components other than thoseavailable through your authorized dealerresults in coolant system damage, engineoverheating, selective catalyst reductionsystem or diesel particulate filter damageand possible 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 sulfur dieselfuel could result in damage to engineemission control devices and the aftertreatment system, potentially renderingthe vehicle inoperable.
Vehicles with engines configured for usewith high-sulfur diesel fuel are onlyavailable for sale in countries whereultra-low sulfur diesel fuel is generally notavailable or mandated by the government.Vehicles originally sold in an ultra-lowsulfur diesel fuel market that aresubsequently exported to non-ultra lowsulfur diesel fuel markets will need to beretrofitted at the customer’s expense usingFord authorized dealer service parts inorder to be reliably operated on non-ultralow sulfur diesel fuel.
Biodiesel
WARNING: Do not mix diesel withgasoline, gasohol or alcohol. This couldcause an explosion.
Note:Do not use home heating oil,agricultural fuel, raw fats and oils, wastecooking greases, biodiesel greater than 20%or any diesel not intended for highway use.Damage to the fuel injection system, engineand exhaust catalyst, and diesel particulatefilter can occur if you use an improper fuel.Red dye is used to identify fuels intendedfor agricultural and non-highway use.
You can 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.
