•The gearshift lever must be in P (Park)or N (Neutral) in order for the starterto operate.
•Try operating the starter switch severaltimes. This operation may cleanpotentially corroded contacts or makethe switch temporarily operable untilyou can reach the dealer.
•If all electrical connections are tightand you need assistance to start, SeeJump Starting the Vehicle (page 190).
If engine cranks but won’t start
Prolonged starter cranking (in excess of 10seconds) could cause damage to thestarter motor or the high-pressure fuelpump.
•Check the fuel gauge. You may be outof fuel. If the gauge shows that thereis fuel in the tank, the trouble may bein the electrical system or the fuelsystem. If equipped with an auxiliarytank, be sure that the tank controlswitch is set for the tank with fuel andnot on an empty tank.
•Leaving your ignition key turned to onfor over two minutes without startingmay make starting difficult becausethe glow plugs will cease activation.Reset the system by turning the ignitionkey to off and then back to on again.
Note:If the system is out of fuel and theengine will not start, do not continuecranking the engine. Continued cranking candamage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine tooverheat:
•Lack of coolant
•Dirty cooling system.
•Plugged radiator fins, A/C condenserand/or oil cooler
•Malfunctioning fan drive
•Driving with frozen coolant
•Sticking thermostat
•Overloading or pulling heavy trailersduring hot weather
•Grill or radiator air blockage
•Slipping or missing drive belt
•Plugged or very dirty air filter
If fuses burn out
WARNING: Replacement fuses andcircuit breakers must always be thesame rating as the original equipmentshown. Never replace a fuse or circuitbreaker with one of a higher rating.Higher rated fuses or circuit breakerscould allow circuit overloading in theevent of a circuit malfunction, resultingin severe vehicle damage or personalinjury due to fire.
Burned-out or blown fuses usually indicatean electrical short-circuit, although a fusemay occasionally burn out from vibration.Insert a second fuse. If this fuseimmediately burns out and you cannotlocate the cause, return your vehicle toyour dealer for a circuit check. SeeChanging a Fuse (page 211).
Selective catalytic reduction systemspeed limit and Idle-only modes
If the vehicle’s speed is limited or in anidle-only mode, the selective catalyticreduction system may be limiting thevehicle’s functions due to low orcontaminated DEF. Check the DEF. SeeSelective Catalytic Reductant System(page 120).

Note:Do not blend used engine oil withdiesel fuel under any circumstances.Blending used oil with the fuel willsignificantly increase your vehicle’s exhaustemissions and reduce engine life due toincreased internal wear.
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 may 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), it isrecommended to use a diesel fuel whichhas been seasonally adjusted for theambient conditions.
Fuel Requirements - Choosing TheRight Fuel: Vehicles OperatedWhere Ultra Low Sulfur Diesel FuelIs 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 usingFord Motor Company dealer service parts.Failure to use retrofit components otherthan those available through yourauthorized dealer will result in coolantsystem damage, engine overheating,selective catalyst reduction system ordiesel particulate filter damage andpossible 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 SulfurDiesel fuel may result in damage to engineemission control devices and theaftertreatment system, potentiallyrendering the vehicle inoperable.
Vehicles with engines configured for usewith high sulfur diesel fuel are onlyavailable for sale in countries where ultralow sulfur diesel fuel is generally notavailable or mandated by the government.Vehicles originally sold in a ultra low sulfurdiesel fuel market that are subsequentlyexported to non- ultra low sulfur diesel fuelmarkets will need to be retrofitted (at thecustomer’s expense using Ford authorizeddealer service parts) in order to be reliablyoperated on non- ultra low sulfur dieselfuel.
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 fuels greater than20% or any diesel fuel not intended forhighway use. Red dye is used to identifyfuels intended for agricultural andnon-highway use. Damage to the fuelinjection system, engine and exhaustcatalyst can occur if an improper fuel isused.
You may operate your vehicle on dieselfuels containing up to 20% biodiesel, alsoknown as B20.

9.Start your vehicle.
Perform Steps 4 through 8 in reverse order,making sure to engage the hinge pivotsbetween the upper and lower halves of theshroud. Keep slight pressure in the forwarddirection as you rotate the halves together.
If Your Vehicle Gets Stuck in Mudor Snow
Note:Do not rock your vehicle if the engineis not at normal operating temperature ordamage to the transmission could occur.
Note:Do not rock your vehicle for morethan a minute or damage to thetransmission and tires could occur, or theengine could overheat.
If your vehicle is stuck in mud or snow, youcould rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
POWER TAKE-OFF (IF EQUIPPED)
Auxiliary equipment called power take-off,or PTO, is often added to the engine ortransmission to operate utility equipment.Examples include a wheel-lift for towtrucks, cranes, tools for construction or tireservice and pumping fluids. PTOapplications draw auxiliary horsepowerfrom the powertrain, often while the
vehicle is stationary or mobile. In thestationary condition, there is limitedcooling air flow through the radiator andaround the vehicle that normally occurswhen a vehicle is moving. The aftermarketPTO system installer, having the mostknowledge of the final application, isresponsible for determining whetheradditional chassis heat protection orpowertrain cooling is required and alertingthe user to the safe and proper operation.
Your vehicle is approved for use as aStationary Mode, SplitShaft Mode orMobile Mode power source within the limitsand operating guidelines detailed in theFord Truck Body Builders Layout Book,found at https://fordbbas.com/home andthrough the Ford Truck Body BuildersAdvisory Service. The transmission powersource modes are engine specific.

Hilly Condition and Trailer TowUsage
You should select a lower gear when thesystem is active in situations such asprolonged downhill driving on steepgrades, for example in mountainous areas.The system needs additional enginebraking in these situations to reduce theload on the vehicle’s regular brake systemto prevent it from overheating.
Note:An audible alarm sounds and thesystem shuts down if it applies brakes foran extended period of time. This allows thebrakes to cool. The system functionsnormally again after the brakes cool.
Note:When towing with adaptive cruisecontrol, switch on Tow/Haul mode.
Switching Adaptive Cruise ControlOff
Press and release the buttonwhen the system is in standbymode, or switch the ignition off.
Note:The set speed and gap setting iserased when you switch the system off.
Detection Issues
WARNING: On rare occasions,detection issues can occur due to theroad infrastructures, for example bridges,tunnels and safety barriers. In thesecases, the system may brake late orunexpectedly. At all times, you areresponsible for controlling your vehicle,supervising the system and intervening,if required.
WARNING: If the systemmalfunctions, have your vehicle checkedas soon as possible.
The radar sensor has a limited field of view.It may not detect vehicles at all or detecta vehicle later than expected in somesituations. The lead vehicle graphic doesnot illuminate if the system does notdetect a vehicle in front of you.
Detection issues can occur:
When driving on a different linethan the vehicle in front.A
With vehicles that edge into yourlane. The system can only detectthese vehicles once they movefully into your lane.

STEERING
Hydraulic Power Steering
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.
