GENERAL INFORMATION
WARNING: Extended idling at highengine speeds can produce very hightemperatures in the engine and exhaustsystem, creating the risk of fire or otherdamage.
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: Do not start the enginein a closed garage or in other enclosedareas. Exhaust fumes are toxic. Alwaysopen the garage door before you startthe engine. Failure to follow thisinstruction could result in personal injuryor death.
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.
The powertrain control system meets allCanadian interference-causing equipmentstandard requirements regulating theimpulse electrical field or radio noise.
Note:If you use your vehicle regularly abovethe altitude of 7,500 ft (2,286 m) and underthe temperature of -4.0°F (-20°C), it isrecommended to use the alternative engineoil. See Capacities and Specifications(page 291).
If you disconnect the battery, your vehiclecould exhibit some unusual drivingcharacteristics for approximately 5 mi(8 km) after you reconnect it. This isbecause the engine management systemmust realign itself with the engine. You candisregard any unusual drivingcharacteristics during this period.
When you start the engine, avoid pressingthe accelerator pedal before and duringoperation.
If you operate your vehicle in a heavy snowstorm or blowing snow conditions, theengine air induction could become partiallyclogged with snow and ice. If this occurs,the engine could experience a significantreduction in power output. At the earliestopportunity, clear all the snow and iceaway from the air induction inlet.

2.Put the transmission into neutral (N)and use the brakes to bring your vehicleto a safe stop.
3.When your vehicle has stopped, shiftinto park (P).
4.Apply the parking brake.
Guarding Against Exhaust Fumes
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.
Important Ventilating Information
If you stop your vehicle and leave theengine idling for long periods of time, werecommend you either open the windowsat least 1 in (3 cm) or set the climatecontrol to outside air.
STARTING A DIESEL ENGINE
Read all starting instructions carefullybefore you start your vehicle.
The 6.7L diesel engine incorporates a delaybetween a crank command and starterengagement to crank the engine. Thisdelay ensures robust starting performancein all environmental conditions includingextreme cold. The crank command isinitiated by the operator by turning theignition key. The delay varies with enginecoolant temperature. There is no delay forhot coolant temperature. The delayincreases at colder coolant temperatures.Maximum delay of 2.5 seconds isexperienced below -13.0°F (-25°C).
Diesel Engine Fast Start Glow PlugSystem
The diesel engine glow system consists of:
•Eight glow plugs, one per cylinder.
•Glow plug control module.
•Engine coolant temperature sensor.
•Barometric pressure sensor.
•Environmental temperature sensor.
The powertrain and glow plug controlmodules electronically control the glowplug system. After you switch the ignitionon, the glow plug control moduleimmediately energizes the glow plugs. Theglow plug control module, using the enginecoolant temperature, barometric pressuresensor and environmental temperaturesensor, determines how long the glowplugs stay energized. The required time forthe glow plugs to be energized decreasesas the coolant temperature, barometricpressure and environmental temperatureincrease.
Before starting the engine, check thefollowing:
•Make sure all occupants fasten theirseatbelt.
•Make sure the headlamps andelectrical accessories are off.
•Make sure the parking brake is on.
•Make sure the transmission is in park(P) or neutral (N).
•Turn the ignition key to the on position.
Note:Do not press the accelerator duringstarting.
1.Fully press the brake pedal.
2.Turn the key to the start position tostart the engine. Release the key whenthe engine starts.

Cold Weather Starting
WARNING: Do not use startingfluid, for example ether, in the air intakesystem. Such fluid could causeimmediate explosive damage to theengine and possible personal injury.
WARNING: Do not mix diesel withgasoline, gasohol or alcohol. This couldcause an explosion.
We recommend using the engine blockheater for starting when the ambienttemperature is at or below -9°F (-23°C).See Engine Block Heater (page 105).
When operating in cold weather, you canuse 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 fails to start, turn the key to theoff position and wait 30 seconds beforetrying again.
Your vehicle may come with a coldweather starting strategy that preventssevere engine damage by assisting inengine lubrication warm-up. In extremelycold ambient temperatures, this strategyactivates and prevents the acceleratorpedal use for 30 seconds after startingyour vehicle. A message appears in theinformation display as your vehicle warmsup. By not allowing the accelerator pedaluse, the engine oil can properly lubricatethe bearings preventing engine damagedue to lack of proper lubrication. After the30 second warm-up period, theaccelerator pedal is operational again anda message appears informing you that yourvehicle is ready to drive.
When starting the engine in extremely coldtemperatures, for example -15°F (-26°C),we recommend you allow the engine toidle for several minutes before driving yourvehicle.
Illuminates when you switch theignition on as part of thepre-starting system.
1.Turn the key to the on position withoutturning the key to the start position. Donot start the engine until the wait tostart indicator turns off.
2.When the wait to start indicator turnsoff, turn the key to the start positionand release the key as soon as theengine starts. Once the engine starts,the glow plugs may remain on for aperiod. If you attempt to start theengine before the glow plug activationtime ends, but it fails to start, reset theglow plugs by turning the key to the offposition.
3.Once the engine starts, allow it to idlefor about 15 seconds. This is to protectthe engine. Do not increase enginespeed until the oil pressure gaugeindicates normal pressure.
SWITCHING OFF THE ENGINE
Allow the engine to idle for three to fiveminutes before shutting it down. The largerthe engine, the greater the need is for thisidling period.
Note:Try to limit engine idle to 10 minutes.Excessive idling reduces fuel economy.

ENGINE IDLE SHUTDOWN (IF
EQUIPPED)
WARNING: In the event of engineshutdown, make sure your vehicle issafely off the road and the problem isresolved before returning to the road.Failure to do so may result in a crash,serious injury or death.
This feature automatically shuts down theengine when it has been idling in park (P)or neutral (N) for an extended period,depending on the setting.
When the engine idle shutdown processhas started:
•A chime sounds and a messageappears in the information displayshowing a timer counting down from30 seconds.
•You can reset the timer by pressing thebrake pedal, accelerator pedal, or byshifting into another gear.
•If you do not intervene within 30seconds, the engine shuts down and amessage appears in the informationdisplay alerting you that the engine hasshut down.
•Shortly after the engine has shut down,the electrical system simulates a keyoff and even though the ignition is stillon, the electrical system simulates anormal accessory delay period beforeshutting down.
•You must switch the ignition off toreset the system before restarting yourvehicle.
The engine idle shutdown timer does notstart if:
•The engine is operating in batterycharge protect or power take-off mode.
•The exhaust emission control device isregenerating.
ENGINE BLOCK HEATER (IF
EQUIPPED)
WARNING: Failure to follow engineblock heater instructions could result inproperty damage or serious personalinjury.
WARNING: Do not use your heaterwith ungrounded electrical systems ortwo-pronged adapters. There is a risk ofelectrical shock.
WARNING: Do not fully close thehood, or allow it to drop under its ownweight when using the engine blockheater. This could damage the powercable and may cause an electrical shortresulting in fire, injury and propertydamage.
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.

We recommend that you do the followingfor a safe and correct operation:
•Use a 16-gauge outdoor extension cordthat is product certified byUnderwriter’s Laboratory (UL) orCanadian Standards Association(CSA). This extension cord must besuitable for use outdoors, in coldtemperatures, and be clearly markedSuitable for Use with OutdoorAppliances. Do not use an indoorextension cord outdoors. This couldresult in an electric shock or become afire hazard.
•Use as short an extension cord aspossible.
•Do not use multiple extension cords.
•Make sure that when in operation, theextension cord plug and heater cordplug connections are free and clear ofwater. This could cause an electricshock or fire.
•Make sure your vehicle is parked in aclean area, clear of combustibles.
•Make sure the heater, heater cord andextension cord are firmly connected.
•Check for heat anywhere in theelectrical hookup once the system hasbeen operating for approximately 30minutes.
•Make sure the system is unplugged andproperly stowed before starting anddriving your vehicle. Make sure theprotective cover seals the prongs of theblock heater cord plug when not in use.
•Make sure the heater system ischecked for proper operation beforewinter.
Using the Engine Block Heater
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 heater longer than three hoursdoes not improve system performance andunnecessarily uses electricity.

SAFETY PRECAUTIONS
WARNING: Do not overfill the fueltank. The pressure in an overfilled tankmay cause leakage and lead to fuel sprayand fire.
WARNING: The fuel system maybe under pressure. If you hear a hissingsound near the fuel filler inlet, do notrefuel until the sound stops. Otherwise,fuel may spray out, which could causeserious personal injury.
WARNING: Fuels can cause seriousinjury or death if misused or mishandled.
WARNING: Gasoline may containbenzene, which is a cancer-causingagent.
WARNING: When refueling alwaysshut the engine off and never allowsparks or open flames near the fuel tankfiller valve. Never smoke or use a cellphone while refueling. Fuel vapor isextremely hazardous under certainconditions. Avoid inhaling excess fumes.
WARNING: Flow of fuel through afuel pump nozzle can produce staticelectricity. This can cause a fire if you arefilling an ungrounded fuel container.
WARNING: Stop refueling after thefuel pump nozzle automatically shutsoff for the second time. Failure to followthis will fill the expansion space in thefuel tank and could lead to fueloverflowing.
Observe the following guidelines whenhandling automotive fuel:
•Extinguish all smoking materials andany open flames before refueling yourvehicle.
•Automotive fuels can be harmful orfatal if swallowed. Fuel such asgasoline is highly toxic and ifswallowed can cause death orpermanent injury. If swallowed, call aphysician immediately, even if nosymptoms are immediately apparent.The toxic effects of fuel may not bevisible for hours.
•Avoid inhaling fuel vapors. Inhaling toomuch fuel vapor of any kind can leadto eye and respiratory tract irritation.In severe cases, excessive or prolongedbreathing of fuel vapor can causeserious illness and permanent injury.
•Avoid getting fuel liquid in your eyes. Ifyou splash fuel in your eyes, removecontact lenses (if worn), flush withwater for 15 minutes and seek medicalattention. Failure to seek propermedical attention could lead topermanent injury.
•Fuels can also be harmful if absorbedthrough the skin. If you splash fuel onyour skin, clothing or both, promptlyremove contaminated clothing andwash your skin thoroughly with soapand water. Repeated or prolonged skincontact with fuel liquid or vapor causesskin irritation.
•Be particularly careful if you are taking“Antabuse” or other forms of disulfiramfor the treatment of alcoholism.Breathing gasoline vapors, or skincontact could cause an adversereaction. In sensitive individuals, serious

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.
