Guarding Against Exhaust Fumes
WARNING
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your vehicle inspectedimmediately. Do not drive if you smellexhaust fumes.
Important Ventilating Information
If you stop your vehicle and then leave theengine idling for long periods of time, werecommend that you do one of thefollowing:
•Open the windows at least 1 inch (2.5centimeters).
•Set your climate control to outside air.
STARTING A DIESEL ENGINE -
6.7L DIESEL
Read all starting instructions carefullybefore you start your vehicle.
For temperatures below 32°F (0°C), theuse of the correct grade engine oil isessential for proper operation. Refer toengine oil specifications for moreinformation. See Capacities andSpecifications (page 427).
Your vehicle may have a cold weatherstarting strategy that prevents severeengine damage by assisting in enginelubrication warm-up. In extremely coldambient temperatures, this strategyactivates and prevents the acceleratorpedal from being used for 30 seconds afteryou start your vehicle. A message appearsin the information display as your vehiclewarms up. By not allowing the acceleratorpedal to be used, the engine oil is allowedto properly lubricate the bearings
preventing engine damage due to lack ofproper lubrication. After the 30 secondwarm-up period, the accelerator pedal willbe operational again and a messageappears informing you the vehicle is ok todrive.
When you start the engine in extremelycold temperatures -15°F (-26°C), werecommend that you allow the engine toidle for several minutes before you drivethe vehicle.
Before starting the engine check thefollowing:
•Make sure all occupants have fastenedtheir seatbelts.
•Make sure the headlamps andelectrical accessories are off.
•Make sure the parking brake is on.
•Make sure the transmission is in park(P).
Note:Do not press the accelerator duringstarting.
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 uses the enginecoolant temperature, barometric pressuresensor and environmental temperature

sensor to determine how long the glowplugs stay energized. The required time forthe glow plugs to be energized decreasesas the coolant temperature, barometricpressure and environmental temperatureincrease.
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

Your vehicle has a fuel and water separatorthat recirculates fuel from the engine tohelp prevent fuel filter clogging. To avoidengine fuel starvation during cold weatheroperation of 32°F (0°C) or below, werecommend that the fuel level in your tankshould not drop below ¼ full. This helpsprevent air from entering the fuel systemand stalling the engine.
Your vehicle has a selective catalyticreduction system that uses Diesel ExhaustFluid (DEF) to operate properly. You needto replenish your vehicle’s DEF at certainintervals. When filling your vehicle’s DEFtank in cold weather, take special care toprevent damage to the tank. SeeSelective Catalytic Reduction System(page 188).
In cold weather below 32°F (0°C), theengine may slowly increase to a higher idlespeed if you leave it idling in park (P). Asthe engine warms-up, the engine soundlevel decreases due to the activation ofPCM-controlled sound reduction features.
If you operate your vehicle in a heavysnowstorm or blowing snow conditions,snow and ice can clog the engine airinduction. If this occurs, the engine mayexperience a significant reduction in poweroutput. At the earliest opportunity, clearall the snow and ice away from inside theair filter assembly. Remove the air cleanercover and the air filter and remove anysnow or ice. Remove any debris, snow orice, on the foam filter by brushing thesurface with a soft brush. Once you havecleared all of the debris, reinstall the airfilter and cover.
Do not use water, solvents, or a hard brushfor cleaning the foam filter.
WARNING
To reduce the risk of vehicle damageand personal burn injuries, do notstart your engine with the air cleanerremoved and do not remove it while theengine is running.
In order to operate the engine intemperatures of 32°F (0°C) or lower, readthe following instructions:
•Make sure that the batteries are ofsufficient size and are fully charged.Check other electrical components tomake sure they are in optimumcondition.
•Use the proper coolant solution at theconcentration recommendedprotecting the engine against damagefrom freezing.
•Try to keep the fuel tank full as muchas possible at the end of operation toprevent condensation in the fuelsystem.
•Make sure you use proper cold weatherengine oil and that it is at its properlevel. Also, if necessary, make sure tofollow the engine oil and filter changeschedule found under the Specialoperating conditions section listed inthe scheduled maintenanceinformation.
•At temperatures of -9°F (-23°C) orbelow, it is recommended that you usean engine block heater to improve coldengine starting.
•If operating in arctic temperatures of-20°F (-29°C) or lower, consult yourtruck dealer for information aboutspecial cold weather equipment andprecautions.

Starting Aids
WARNING
Do not use starting fluid, for exampleether, in the air intake system. Suchfluid could cause immediateexplosive damage to the engine andpossible personal injury.
The use of the factory engine block heaterassists in engine starting in extreme coldambient temperatures See Engine BlockHeater (page 181).
Idle Control
Your vehicle may have a factory option fora stationary elevated idle control throughthe upfitter switches in the overheadconsole. This allows the operator toelevate the idle RPM for extended idleperiods, as well as aftermarket equipmentsuch as PTO operation. You must configurethis feature even if ordered from thefactory. See your authorized dealer forrequired upfitting.
Operation in Snow and Rain
Vehicle operation in heavy snowfall orextreme rain conditions may feedexcessive amounts of snow or water intothe air intake system. This could plug theair filter with snow and may cause theengine to lose power and possibly shutdown.
We recommend the following actions afteroperating your vehicle up to 200 mi(320 km) in snowfall or extreme rain:
•Snow: At the earliest opportunity, openthe hood and clear all the snow and icefrom the air filter housing inlet (do notremove the foam filter) and reset theair filter restriction gauge.
Note:Removal of the foam filter degradesyour vehicle performance during snow andhot weather conditions.
•Extreme rain: The air filter dries afterabout 15–30 minutes at highwayspeeds. At the earliest opportunity,open the hood and reset the air filterrestriction gauge.
Refer to Air filter and restriction gauge inthe Maintenance chapter for moreinformation. See Changing the EngineAir Filter (page 357).

Operation in Standing Water
Ingestion of water into the diesel enginecan result in immediate and severedamage to the engine. If driving throughwater, slow down to avoid splashing waterinto the intake. If the engine stalls, and yoususpect ingestion of water into the engine,do not try to restart the engine. Consultyour dealer for service immediately.
Your fuel tank vents to the atmosphere byvalves on top of the tank and through thefuel cap. If water reaches the top of thetank, the valves may pull water into thefuel tank. Water in the fuel can causeperformance issues and damage the fuelinjection system.
DIESEL PARTICULATE FILTER
The filter forms part of the emissionsreduction system on your vehicle. It filtersharmful diesel particulates (soot) from theexhaust gas.
Regeneration
WARNING
Do not park or idle your vehicle overdry leaves, dry grass or othercombustible materials. Theregeneration process creates very highexhaust gas temperatures and the exhaustwill radiate a considerable amount of heatduring and after regeneration and after youhave switched the engine off. This is apotential fire hazard.
Note:Avoid running out of fuel.
Note:During regeneration at low speed orengine idle, you may smell a hot metallicodor and could notice a clicking metallicsound. This is due to the high temperaturesreached during regeneration and is normal.
Note:Changes in the engine or exhaustsound may be heard during the regenerationprocess.
The diesel particulate filter on your vehiclerequires periodic regeneration to maintainits correct function. Your vehicle will carryout this process automatically.
If your journeys meet one of the followingconditions:
•You drive only short distances.
•You frequently switch the ignition onand off.
•Your journeys contain a high level ofacceleration and deceleration.
You must carry out occasional trips withthe following conditions to assist theregeneration process:
•Drive your vehicle in more favorableconditions, which you will find at highervehicle speeds in normal driving, on amain road or freeway for a minimumof 20 minutes. This drive may includeshort stops that will not affect theregeneration process.
•Avoid prolonged idling and alwaysobserve speed limits and roadconditions.
•Do not switch the ignition off.
•Select a suitable gear to ideallymaintain engine speed between 1500and 3000 RPM.

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.
