2024 FORD F650/750 warning

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.

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.
108
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and Refueling

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.

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.
112
2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingFuel and Refueling

WARNING: Wait at least fiveseconds before removing the fuel pumpnozzle to allow any residual fuel to draininto the fuel tank.
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.
WARNING: Do not remove the fuelpump nozzle from its fully insertedposition when refueling.
An engine that suddenly becomes noisy oroperates poorly after a fuel fill could beusing substandard fuel. We recommendthat you purchase diesel fuel from areputable fuel station.
Use only clean, approved containers thatprevent the entry of dirt or water wheneveryou store diesel fuel.
Do not store diesel fuel in a galvanizedcontainer. The fuel dissolves the zinc in thegalvanized container. The zinc will thenremain in the fuel. If you run thecontaminated fuel through the engine, thezinc damages the fuel injectors. Enginedamage caused may not be covered bythe vehicle warranty.
Use the following guidelines to avoidelectrostatic charge build-up when fillingan ungrounded fuel container:
•Place the approved fuel container onthe ground.
•Do not fill a fuel container while it is inthe vehicle (including the cargo area).
•Keep the fuel pump nozzle in contactwith the fuel container when filling.
•Do not use a device that would holdthe fuel pump handle in the fill position.
Fuel Filler Cap
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.
Note:If you do not use the correct fuel fillercap, excessive pressure or vacuum in thefuel tank may damage the fuel system orcause the fuel cap to disengage in a crash.
The fuel tank has a threaded fuel filler cap.
Note:If you must replace the fuel filler cap,replace it with a fuel filler cap that isdesigned for your vehicle. The vehiclewarranty may be void for any damage to thefuel tank or fuel system if the correctgenuine Ford, Motorcraft or other certifiedfuel filler cap is not used.
When refueling the vehicle fuel tank do thefollowing:
1.Bring your vehicle to a complete stopand shift into neutral (N) or park (P).
2.Apply the parking brake and switch theignition off.
3.Turn the fuel filler capcounterclockwise and remove it.
4.Refuel your vehicle as required.
5.Replace the fuel filler cap, turn itclockwise until you feel a strongresistance.
Fuel Fill Rate
Your vehicle has a fuel fill inlet that is ableto accept fuel up to 20 gal (75 L) perminute from a fuel-dispensing nozzle.Pumping fuel at greater flow rates mayresult in premature nozzle shut off or spitback.
