RUNNING OUT OF FUEL -
DIESEL
Avoid running out of fuel. This allows air toenter the fuel system and may make itdifficult to restart your vehicle.
If your vehicle runs out of fuel:
•Normally adding 4–5 gal (15–19 L) offuel is enough to restart the engine. Ifyour vehicle is out of fuel and on asteep grade, more than 5 gal (19 L)may be required.
•You must purge trapped air from thesystem before restarting the engine.
Purging Air From the System
Switch the ignition on for 30 seconds andthen switch the ignition off. Repeat thisoperation six times in a row to purge anytrapped air from the fuel system.
Any remaining air in the system self-purgeswhen the engine starts. The engine mayrun rough or produce white smoke whenair remains in the fuel system. This isnormal and stops after a short period. Ifthe engine continues to run rough, haveyour vehicle checked as soon as possible.
Starting the Engine
Do not crank the engine for more than 10seconds as starter damage may occur. Ifthe engine fails to start, switch the ignitionoff and wait 30 seconds before crankingthe engine again. See Starting a DieselEngine (page 103).
RUNNING OUT OF FUEL -
GASOLINE
Avoid running out of fuel because thissituation may have an adverse effect onpowertrain components.
If you run out of fuel:
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal. With keyless ignition, just startthe engine. Crank time will be longerthan usual.
•Normally, adding 1 gal (3.8 L) of fuel isenough to restart the engine. If thevehicle is out of fuel and on a steepgrade, more than 1 gal (3.8 L) may berequired.
•The service engine soon indicator maycome on. See Warning Lamps andIndicators (page 67).
REFUELING - DIESEL
WARNING: Fuel vapor burnsviolently and a fuel fire can cause severeinjuries.
WARNING: Read and follow all theinstructions on the pump island.
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: Stay outside yourvehicle and do not leave the fuel pumpunattended when refueling your vehicle.
WARNING: Keep children awayfrom the fuel pump. Never let childrenpump fuel.

Note:If these checks do not help youcorrect the concern, have your vehiclechecked as soon as possible.
Noise Emissions Warranty,Prohibited Tampering Acts andMaintenance
On January 1, 1978, Federal regulationbecame effective governing the noiseemission on trucks over 10,000 lb(4,536 kg) Gross Vehicle Weight Rating(GVWR). The preceding statementsconcerning prohibited tampering acts andmaintenance, and the noise warrantyfound in the Warranty Guide, areapplicable to complete chassis cabs over10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
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: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
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.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 190).
•Use only the specified fuel listed.
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Resulting component damage maynot be covered by the vehicle Warranty.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.

As the diesel exhaust fluid levelnears empty, the warningsymbol displays and a series oftones and messages starting at 500 mi(800 km) remaining before diesel exhaustfluid is depleted. The warning symbol andmessages continue until you refill thediesel exhaust fluid tank.
Continued driving without refilling resultsin the following actions as required by theCalifornia Air Resources Board (CARB) andthe U.S. Environmental Protection Agency(EPA):
•Within a preset distance to empty,speed is limited upon vehicle restart.Prior to this occurring a messageappears in the information display.
•Further vehicle operation withoutrefilling the diesel exhaust fluid tankcauses the engine to enter an idle-onlycondition. This only occurs upon vehiclerefueling or at an extended idle. Amessage indicates the required actionsto resume normal operation. It isrequired to add a minimum of 1.0 gal(3.8 L) of diesel exhaust fluid to thetank to exit the idle-only condition, butyour vehicle is still in the speed-limitingmode until you refill the tankcompletely.
Note:For either vehicle speed limiting oridle-only condition, normal vehicle operationresumes when you refill the diesel exhaustfluid tank.
Note:When filling the diesel exhaust fluidtank from empty, there may be a short delaybefore detecting the increased level of fluid.The increased level detection must occurbefore your vehicle returns to full power.
Diesel Exhaust Fluid Guidelinesand Information
•Use only diesel exhaust fluid thatcarries the American PetroleumInstitute (API) certified diesel exhaustfluid trademark or ISO 22241.
•Do not put diesel exhaust fluid in thediesel fuel tank. If this happens, do notswitch the ignition on. Drain the fueltank as soon as possible.
•Do not overfill the diesel exhaust fluidtank.
•Diesel exhaust fluid is corrosive.
•Do not reuse the diesel exhaust fluidcontainer once it is emptied.
•Avoid spilling diesel exhaust fluid onpainted surfaces, carpeting or plasticcomponents. Immediately wipe awayany diesel exhaust fluid that has spilledwith a damp cloth and water. If it hasalready crystallized, use warm waterand a sponge.
•Store diesel exhaust fluid out of directsunlight and in temperatures between23°F (-5°C) and 68°F (20°C).
•Diesel exhaust fluid freezes below 12°F(-11°C).
•Do not store the diesel exhaust fluidbottle in your vehicle. If it leaks it coulddamage interior components or releasean ammonia odor inside your vehicle.
•Diesel exhaust fluid is anon-flammable, non-toxic, colorlessand water-soluble liquid.
•The system has a diesel exhaust fluidquality sensor. Dilution of dieselexhaust fluid or use of any other liquidin the selective catalytic reductionsystem leads to a diesel exhaust fluidsystem fault, eventually leading to thevehicle only operating in idle-onlymode.

•Do not dilute diesel exhaust fluid withwater or any other liquid.
•An ammonia odor may be smelledwhen the cap is removed or duringrefill. Refill diesel exhaust fluid in a wellventilated area.
Typical Diesel Exhaust Fluid UsageWhen Using the Power Take Off (PTO)
Continuous PTO use—Minimal PTO use
0–7,800 mi (0–12,550 km)
Contaminated Diesel ExhaustFluid or Inoperative SelectiveCatalytic Reduction System
Selective catalytic reduction systems aresensitive to contamination of the dieselexhaust fluid. Maintaining the purity of thefluid is important to avoid systemmalfunctions. Do not add fuel or anyadditive to the diesel exhaust fluid tank. Ifyou remove or drain the diesel exhaust fluidtank, do not use the same fluid to refill thetank. The system has a sensor to monitorfluid quality.
A warning lamp illuminates anda message appears in theinformation display if the systembecomes contaminated or inoperative.
Continued driving without replacing dieselexhaust fluid or having the selectivecatalytic reduction system repaired resultsin the following actions as required by theCalifornia Air Resources Board (CARB) andU.S. Environmental Protection Agency(EPA):
•Within a preset distance to empty,speed is limited upon vehicle restart.Prior to this occurring a messageappears in the information display.
•Further vehicle operation withoutreplacing contaminated diesel exhaustfluid causes the engine to enter anidle-only condition. This only occursupon vehicle refueling, vehicle idling inpark for 1 hour, or engine shutdown for10 minutes or more and is indicated bya message in the information displayindicating the required actions toresume normal operation.
Note:For vehicle speed limiting or idle-onlycondition, normal vehicle operation resumeswhen you repair the contaminated system.To service a contaminated or inoperativesystem, see an authorized dealer.
DIESEL PARTICULATE FILTER
Your vehicle has a diesel particulate filter.The diesel particulate filter is an inline filterin the exhaust system that reduces carbonemissions by trapping exhaust particlesbefore they reach the tailpipe. The dieselparticulate filter looks similar to atraditional exhaust catalyst, except larger,and is part of the exhaust system underyour vehicle. The filter couples to a dieseloxidation catalyst that reduces the amountof harmful exhaust emitted from thetailpipe. As soot gathers in the system, itbegins to restrict the filter. Periodically, youneed to clean the soot that gathers insidethe filter. You can clean the soot in twodifferent ways, passive regeneration andactive regeneration. Both methods occur

automatically and require no actions fromthe driver. During either one of theseregeneration methods, you may notice achange in exhaust tone. At certain times,various messages related to the dieselparticulate filter appear in the informationdisplays.
Oxidation Catalytic Converter andDiesel Particulate Filter System (If
Equipped)
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the diesel oxidationcatalytic converter or the dieselparticulate filter. The diesel oxidationcatalytic converter and the dieselparticulate filter heat up to very hightemperatures after only a short periodof engine operation and remain hot afteryou switch the engine off.
Diesel Particulate Filter Maintenance
You must properly maintain your vehicle'sdiesel particulate filter in order for it tofunction properly.
Do not disregard maintenance messagesthat appear in the information display.Failure to follow the instructions of aninformation message may degrade vehicleperformance and could lead to enginedamage that may not be covered by thevehicle Warranty.
Failure to perform active or operatorcommanded regeneration when instructedcould result in a clogged diesel particulatefilter. If the diesel particulate filter fillsbeyond the regeneration threshold, yourvehicle disables the ability for active andoperator commanded regeneration. Thiscould result in irreversible damage to thediesel particulate filter requiringreplacement that may not be covered bythe vehicle Warranty.
Passive Regeneration
In passive regeneration, the exhaustsystem temperature and constituentsautomatically clean the filter by oxidizingthe soot. Cleaning automatically occursduring normal vehicle operating conditionsdue to driving patterns.
Active Regeneration
Once the diesel particulate filter is full ofexhaust particles, the engine controlmodule commands the exhaust system toclean the filter through active regeneration.Active regeneration requires the enginecomputer to raise the exhaust temperatureto eliminate the particles. During cleaning,the particles convert to harmless gasses.Once cleaned the diesel particulate filtercontinues trapping exhaust particles.
The regeneration process operates moreefficiently when you drive your vehicle ata constant speed above 30 mph(48 km/h) and at a steady engine speedfor approximately 20 minutes. Thefrequency and duration of regenerationfluctuates by how you drive your vehicle,outside air temperature and altitude. Formost driving, regeneration frequency variesfrom 100–500 mi (160–805 km) betweenoccurrences and each occurrence lasts9–35 minutes. You can usually reduce theduration of regeneration if you maintain aconstant speed above 30 mph (48 km/h).

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.

GENERAL INFORMATION
WARNING: Exceeding these ratingsby overloading can cause componentfailure resulting in property damage,personal injury or death.
Fluid Temperature
If the operating temperature exceeds250°F (121°C), the rate of axle lubricationoxidation increases and shortens the lifeof the lubricant and seals, requiring axlelubrication changes to become morefrequent to preserve the axle. Do notconsistently run extreme pressure (EP)lubricants above 250°F (121°C).
Axle Conversions
WARNING: When operating aloaded vehicle, the driver must keep alladjustable axles on the ground at alltimes, supporting their share of thevehicle’s load. Failure to do so canoverload other axles, tires, wheels,springs, steering components, brakesand frames, resulting in early componentfailure, loss of vehicle control, possibleproperty damage and personal injury.
We do not recommend, or approve,performing axle conversions. However, weunderstand that, on occasion, others installaftermarket add-on axles on the truckchassis that allow operator control forweight transfer from other axles (such asair lift axles).
2-SPEED REAR AXLE (IF EQUIPPED)
WARNING: Never shift atwo-speed axle when descending asteep grade as this may cause loss ofvehicle control and result in personalinjury.
Note:Do not shift between ranges whenthe speed control is on.
A two-speed rear axle allows the driver toselect a low range for greater pulling powerand a high range for greater road speedand fuel economy. You can also use theseranges to provide extra steps betweentransmission shifts when driving on steepgrades or fuel economy may be factors.
Axle Shifting
Note:Do not shift the axle to LOW whenyour vehicle is moving. Use LOW when youdrive a fully loaded vehicle on a severe gradeor in congested traffic. Use HIGH for allnormal driving conditions with a lightlyloaded or partially loaded vehicle.
Note:The axle is set to HIGH by default.
To shift the axle between HIGH and LOWwith the vehicle stopped, place thetransmission in position N, then press andhold the button for two seconds.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out. Have thesystem checked as soon as possible. If thevehicle has continuous vibration or shudderin the steering wheel while braking, have thesystem checked as soon as possible.
All standard equipment brakes areself-adjusting. Automatic adjustment,when required, occurs whenever you applyand release the brakes during forward orreverse operation.
Know the required stopping distances forall driving conditions you may encounter.For longer brake lining life, take fulladvantage of engine braking power whencoming to a stop.
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
If the brakes do not grip well:
•Check brake adjustment.
•Check the brake linings for excessivewear.
•Check the system air pressure onvehicles with air brakes.
•Let the brakes cool if you have beenusing them excessively, as in mountaindriving or after several fast, high-speedstops.
•If you have been driving through deepwater, gently apply the brakes severaltimes while your vehicle is movingslowly.
Brake Over Accelerator
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
If the light does not illuminateduring start up, remains on orflashes, the system may bedisabled. It also momentarily illuminateswhen you switch the ignition on to confirmthe lamp is functional. If it does notilluminate when you switch the ignition on,or begins to flash at any time, have thesystem checked.
If you connect a PLC trailer withthe ignition on, the trailer ABSlight also illuminates. If the lightfails to illuminate, if it remains on after youstart the vehicle or continues to flash, havethe system serviced immediately.
