GENERAL INFORMATION
WARNINGS
Extended idling at high enginespeeds can produce very hightemperatures in the engine andexhaust system, creating the risk of fire orother damage.
Do not park, idle or drive your vehicleon dry grass or other dry groundcover. The emission system heats upthe engine compartment and exhaustsystem, creating the risk of fire.
Do not start the engine in a closedgarage or in other enclosed areas.Exhaust fumes can be toxic. Alwaysopen the garage door before you start theengine.
If you smell exhaust fumes insideyour vehicle, have your vehiclechecked by your authorized dealerimmediately. Do not drive your vehicle ifyou smell exhaust fumes.
If you disconnect the battery, your vehiclemay exhibit some unusual drivingcharacteristics for approximately 5 miles(8 kilometers) after you reconnect it. Thisis because the engine management systemmust realign itself with the engine. You candisregard any unusual drivingcharacteristics during this period.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
When you start the engine, avoid pressingthe accelerator pedal before and duringoperation. Only use the accelerator pedalwhen you have difficulty starting theengine.
If your vehicle is operated in a heavy snowstorm or blowing snow conditions, theengine air induction may become partiallyclogged with snow and ice. If this occurs,the engine may experience a significantreduction in power output. At the earliestopportunity, clear all the snow and iceaway from the air induction inlet.
IGNITION SWITCH (If Equipped)

Failure to Start
If you cannot start the engine after threeattempts, wait 10 seconds and follow thisprocedure:
1. Fully depress the brake pedal.
2. Fully press the accelerator pedal andhold it there.
3. Start the engine.
Stopping the Engine When YourVehicle is Stationary
1. When your vehicle has stopped, shiftinto park (P) and switch the ignitionoff.
2. Apply the parking brake.
Stopping the Engine When YourVehicle is Moving
WARNING
Switching off the engine when thevehicle is still moving will result in aloss of brake and steering assistance.The steering will not lock, but higher effortwill be required. When the ignition isswitched off, some electrical circuits,including air bags, warning lamps andindicators may also be off. If the ignitionwas turned off accidentally, you can shiftinto neutral (N) and re-start the engine.
1. Put the transmission into neutral (N)and use the brakes to bring your vehicleto a safe stop.
2. When your vehicle has stopped, shiftinto park (P) and switch the ignitionoff.
3. Apply the parking brake.
Cold Weather Starting (FlexibleFuel Vehicles Only)
The starting characteristics of all gradesof E85 ethanol make it unsuitable for usewhen ambient temperatures fall below-0°F (-18°C). Consult your fuel distributorfor the availability of winter grade ethanol.As the outside temperature approachesfreezing, ethanol fuel distributors shouldsupply winter grade ethanol, the same aswith unleaded gasoline.
If summer grade ethanol is used in coldweather conditions, -0°F (-18°C), you mayexperience increased cranking times, roughidle or hesitation until the engine haswarmed up.
You may experience a decrease inperformance when the engine is cold whenoperating on E85 ethanol.
Do not use starting fluid such as ether inthe air intake system. Such fluid couldcause immediate explosive damage to theengine and possible personal injury.
If you should experience cold weatherstarting problems on E85 ethanol, andneither an alternative brand of E85 ethanolnor an engine block heater is available, theaddition of unleaded gasoline to your tankimproves cold starting performance. Yourvehicle is designed to operate on E85ethanol alone, unleaded gasoline alone, orany mixture of the two.
If the Engine Fails to Start Using thePreceding Instructions (Flexible FuelVehicles Only)
1. Press the accelerator pedal downone-third to one-half of its travel, andthen crank the engine.
2. When the engine starts, release thekey, then gradually release theaccelerator pedal as the engine speedincreases. If the engine still does notstart, repeat Step 1.

Cold Weather Starting
WARNINGS
Do not use starting fluid, for exampleether, in the air intake system. Suchfluid could cause immediateexplosive damage to the engine andpossible personal injury.
Do not add gasoline, gasohol, alcoholor kerosene to diesel fuel. Thiscreates a serious fire hazard andcauses engine performance problems.
We recommend that the engine blockheater be used for starting when thetemperature is -9°F (-23°C) or colder. SeeEngine Block Heater (page 181).
When operating in cold weather, you mayuse Motorcraft® cetane improvers ornon-alcohol-based cetane improvers froma reputable manufacturer as needed.
Do not crank the engine for more than 10seconds as starter damage may occur. Ifthe engine does not start, switch theignition off and wait 30 seconds beforetrying again.
Switch the ignition on. Do notstart the engine until theglow-plug indicator turns off.
When the glow plug pre-heat indicatorturns off, turn the key to start. After youstart the engine, the glow plugs mayremain on for a period. If you do not startthe engine before the glow plug activationtime ends, you will need to reset the glowplugs by switching the ignition off. Afterthe engine starts, allow it to idle for about15 seconds. This protects the engine. Donot increase engine speed until the oilpressure gauge indicates normal pressure.
Cold Weather Operation
Note:Idling in cold weather does not heatthe engine to its normal operatingtemperature. Long periods of idling,especially in cold weather, can cause abuildup of deposits which can cause enginedamage.
Change to a lighter grade engine oil tomake starting easier under theseconditions. Refer to engine oilspecifications. See Capacities andSpecifications (page 427).
Diesel fuel is adjusted seasonally for coldtemperatures. Diesel fuel which has notbeen properly formulated for the ambientconditions may gel which can clog the fuelfilters. One indication that the fuel filter(s)may be clogged is if the engine starts, stallsafter a short time, and then does notrestart. If you have been using biodiesel,you may need to use a fuel with lowerbiodiesel content, try another brand, ordiscontinue using biodiesel. Do not usealcohol based additives to correct fuelgelling. This may result in damage to thefuel injectors and system. Use the properanti-gel and performance improvementproduct. See Capacities andSpecifications (page 427).

Starting and Stopping the Engine

To help prolong engine life, werecommended you allow the engine to idlefor three to five minutes, especially afterany of the following:
•Continuous engine speed.
•High ambient temperature.
•High GVW or GCW operation, forexample heavy loads or trailers.
This allows the turbo charged engine tocool down.
ENGINE IDLE SHUTDOWN (If
Equipped)
Your vehicle may be equipped with anengine idle shutdown system. This systemautomatically shuts down your enginewhen it has been idling in P (Park) or N(Neutral) for five minutes (parking brakeset) or 15 minutes (parking brake not set).When the engine idle shutdown processhas started:
•A chime sounds and the informationdisplay will show ENGINE TURNS OFFIN 30 (seconds) and start countingdown
•You can restart the five or 15-minutetimer by changing the position of theaccelerator pedal, brake pedal or thepark brake within the final 30 seconds
•When the timer reaches zero, theengine shuts down and this messagewill appear in your information displayENGINE TURNED OFF
•One minute after the engine has shutdown, the electrical system simulateskey off, even though the ignition is stillin the on position, initiating normalaccessory delay period
•You must move the ignition to the offposition to reset the system beforerestarting your vehicle.
The engine idle shutdown idle timer doesnot start if:
•The engine is operating in powertake-off mode.
•The engine coolant temperature isbelow 60°F (16°C).
•The exhaust emission control device isregenerating.
ENGINE BLOCK HEATER (If
Equipped)
WARNINGS
Failure to follow engine block heaterinstructions could result in propertydamage or serious personal injury.
Do not use your heater withungrounded electrical systems ortwo-pronged adapters. There is a riskof electrical shock.
Note:The heater is most effective whenoutdoor temperatures are below 0°F(-18°C).
The heater acts as a starting aid bywarming the engine coolant. This allowsthe climate control system to respondquickly. The equipment includes a heaterelement (installed in the engine block) anda wire harness. You can connect thesystem to a grounded 120-volt ACelectrical source.

•Fuels containing methanol.
•Fuels containing metallic-basedadditives, including manganese-basedcompounds.
•Fuels containing the octane boosteradditive, methylcyclopentadienylmanganese tricarbonyl (MMT).
•Leaded fuel (using leaded fuel isprohibited by law).
The use of fuels with metallic compoundssuch as methylcyclopentadienylmanganese tricarbonyl (commonly knownas MMT), which is a manganese-basedfuel additive, will impair engineperformance and affect the emissioncontrol system.
Do not be concerned if the enginesometimes knocks lightly. However, if theengine knocks heavily while using fuel withthe recommended octane rating, contactan authorized dealer to prevent any enginedamage.
RUNNING OUT OF FUEL
Avoid running out of fuel because thissituation may have an adverse effect onengine components.
If you have run out of fuel:
•You may need to cycle the ignition fromoff to on several times after refuelingto allow the fuel system to pump thefuel from the tank to the engine. Onrestarting, cranking time will take a fewseconds longer than normal. Withkeyless ignition, just start the engine.Crank time will be longer than usual.
•Normally, adding 1.06 gal (4 L) of fuelis enough to restart the engine. If thevehicle is out of fuel and on a steepgrade, more than 1.06 gal (4 L) may berequired.
SELECTIVE CATALYTIC
REDUCTION SYSTEM - DIESEL
Your vehicle may have a selective catalyticreduction system. The system helps reduceemission levels of oxides of nitrogen fromthe exhaust system. The systemautomatically injects diesel exhaust fluidinto the exhaust system to enable correctselective catalytic reduction systemfunction.
Note:Selective catalytic reduction systemsare not fitted to vehicles in markets whereonly high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctlyyou must maintain the diesel exhaust fluidlevel.
A warning message appears in theinformation display when the dieselexhaust fluid level is low. If a warningmessage appears, refill the diesel exhaustfluid tank as soon as possible. SeeInformation Messages (page 128).
Filling the Diesel Exhaust FluidTank
WARNINGS
Keep diesel exhaust fluid out ofreach of children. Avoid contact withskin, eyes or clothing. In case ofcontact with your eyes, flush immediatelywith water and get prompt medicalattention. In case of contact with your skin,clean immediately with soap and water. Ifyou swallow any diesel exhaust fluid, drinkplenty of water, call a physicianimmediately.

Fuel and Refueling

WARNINGS
When refueling always shut theengine off and never allow sparks oropen flames near the fuel tank fillervalve. Never smoke or use a cell phonewhile refueling. Fuel vapor is extremelyhazardous under certain conditions. Avoidinhaling excess fumes.
Stop refueling after the fuel pumpnozzle automatically shuts off for thesecond time. Failure to follow thiswill fill the expansion space in the fuel tankand could lead to fuel overflowing.
The fuel system may be underpressure. If the fuel filler cap isventing vapor or if you hear a hissingsound, wait until it stops before completelyremoving the fuel filler cap. Otherwise, fuelmay spray out and injure you or others.
If you do not use the proper fuel fillercap, excessive pressure or vacuumin the fuel tank may damage the fuelsystem or cause the fuel cap to disengagein a collision, which may result in possiblepersonal injury.
Note:If you must replace the fuel filler cap,replace it with a fuel filler cap designed foryour vehicle. The vehicle Warranty may bevoid for any damage to the fuel tank or fuelsystem if the correct genuine Ford orMotorcraft® fuel filler cap is not used.
Fueling Tips
If air is allowed to enter the fuel system theengine automatically purges any trappedair. To purge the air sooner: prior to enginestart, prime the system by turning the keyto on for 30 seconds then to off. Repeatthis several times. The engine may runrough and produce white smoke while airis in the system. This is normal.
Use only clean, approved containers thatwill prevent the entry of dirt or waterwhenever you store diesel fuel.
Diesel fuel must not be stored in agalvanized container. The fuel will dissolvethe zinc in the galvanized container. Thezinc will then remain in the fuel. If you runthe contaminated fuel through the engine,the zinc will deposit in the fuel injectorscausing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
Your vehicle has a fuel fill pipe that is ableto accept fuel up to 20 gal (76 L) perminute from an 1.2 in (30 mm)fuel-dispensing nozzle. Pumping fuel atgreater flow rates may result in prematurenozzle shut-off or spit back.
Truck stops have pumps and nozzlesdesigned for larger, heavy-duty trucks.When refueling at truck stops: if the nozzleshuts off repeatedly when refueling, wait5–10 seconds; then use a slower rate offlow, do not depress the nozzle trigger asfar.
Refueling
When fueling your vehicle do the following:
1.Fully open the fuel tank filler door untilit engages and remove the fuel tankfiller cap. The fuel tank filler cap hasan indexed design with a 1/4 turnon/off feature. Carefully turn the fillercap counterclockwise until it spins off.

present, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixed city andhighway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness andlead to more costly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, your vehicle may needservice. See On-Board Diagnostics.
Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, the vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the on
position for 15 seconds without crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing,you can perform the following driving cycleconsisting of mixed city and highwaydriving:
1. 15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2. Allow your vehicle to sit for at leasteight hours with the ignition off. Then,start the vehicle and complete theabove driving cycle. The vehicle mustwarm up to its normal operatingtemperature. Once started, do not turnoff the vehicle until the above drivingcycle is complete.
If the vehicle is still not ready for I/Mtesting, you need to repeat the abovedriving cycle.
