ESSENTIAL TOWING CHECKS
See Load limits in the Load Carryingchapter for load specification terms foundon the tire label and Safety Compliancelabel and instructions on calculating yourvehicle's load.
Remember to account for the trailertongue weight as part of your vehicle loadwhen calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps ontothe bumper or attaches to the axle. Youmust distribute the load in your trailer sothat 10-15% of the total weight of thetrailer is on the tongue.
Safety Chains
Note:Do not attach safety chains to thebumper.
Always connect the safety chains to theframe or hook retainers of your vehiclehitch.
To connect the safety chains, cross thechains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.
Trailer Brakes
WARNING: Do not connect atrailer's hydraulic brake system directlyto your vehicle's brake system. Yourvehicle may not have enough brakingpower and your chances of having acollision greatly increase.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Trailer Lamps
WARNING: Never connect anytrailer lamp wiring to the vehicle's taillamp wiring; this may damage theelectrical system resulting in fire. Contactyour authorized dealer as soon aspossible for assistance in proper trailertow wiring installation. Additionalelectrical equipment may be required.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.
Before Towing a Trailer
Practice turning, stopping and backing upto get the feel of your vehicle-trailercombination before starting on a trip.When turning, make wider turns so thetrailer wheels clear curbs and otherobstacles.
When Towing a Trailer
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mph(80 km/h).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) or neutral (N)to aid engine and transmission coolingand to help air conditioningperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.

VEHICLE INSPECTION
INFORMATION
To make sure your vehicle is ready tooperate, conduct a pre-trip inspection atthe beginning of each work period. Followthe steps listed in this section to verify aproper vehicle inspection procedure.
WARNING: Exercise great cautionwhen working on a vehicle equipped withan automatic fan clutch. The fan startsin motion only after the engine coolantreaches a predetermined temperatureor the refrigerant pressure (if equippedwith air conditioning) reaches apredetermined setting. The fan starts atthis point with no advance warning.Never reach near, or permit objects toprotrude into, the fan blade radius whilethe engine is running as this could resultin vehicle damage, personal injury ordeath.
WARNING: Do not operate thevehicle if any suspension conditionslisted in the following charts are evident.Loss of steering or suspension couldresult in property damage, personal injuryor death.
WARNING: If a wheel must bechanged, obtain expert tire service help.Mounting and un-mounting of tiresshould only be performed by a qualifiedtechnician using necessary safetyprocedures and equipment, otherwisethe result could be property damage,personal injury or death.
Note:Always make sure you apply theparking brake before starting the engine.
Engine compartment (with engine off)
Use the dipstick to verify the oil level is in the proper operatingrange. See Engine Oil Dipstick (page 227).Engine oil
Look through the plastic reservoir and verify the coolant levelis within the proper operating range. Do not remove thepressure cap until the coolant has cooled. See EngineCoolant Check (page 238).
Engine coolant
Verify that the fluid level is in the proper operating range. SeePower Steering Fluid Check (page 246).Power steering fluid
Remove the master cylinder caps and inspect the fluid level.See Brake Fluid Check (page 245).Brake fluid

2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingVehicle Inspection Guide

Engine compartment (with engine off)
Inspect for glazing, fraying or cracking. There should be nomore than 5-7 cracks per rib, per 1 in (2.5 cm)Belts (fan, alternator,water pump and airconditioningcompressor)
Inspect for signs of fluid puddles or dripping fluid on theground under the engine, or the underside of the engine.Fluid leaks
Inspect for debris that may have collected on the HVAC airinlet grille or inside the exterior module as this may reducesystem performance.
HVAC air inlet
Engine starting (with parking brake applied)
Before entering the cab, verify that the vehicle is equippedwith spare electrical fuses (if used), three red reflectivetriangles, a properly charged and rated fire extinguisher andwheel chocks.
Safety and emergencyequipment
Walk around the vehicle and verify all steps and grab handles,inside and out (as well as behind), are tight and clean. Useextreme caution and a three-point stance at all times.
Inspect door latches for proper closing, latching and locking.
Set the parking brake. Make sure the gearshift lever is inneutral (N) or park (P) (if equipped with a park position).Starting the engine
Diesel engine: Turn the key to the on position. Turn the keyto start when the wait to start indicator light in the instrumentcluster turns off.
Gasoline engine: Turn the key to start, and then release itas soon as the engine starts.
Verify pressure builds to normal operating range.Engine oil pressure
A tone indicating low air pressure should sound immediatelyafter the engine starts but before the compressor has built-up pressure. The tone should stop when the air pressurereaches 70 psi (483 kPa). Let the air pressure build togoverned cutout pressure, which should occur between115–130 psi (793–896 kPa).
Low air pressure warningtone (if equipped with anair compressor)
Press the accelerator and verify that it operates smoothly,without any binding or irregular feel. Release the pedal andverify the engine returns to idle speed immediately.

If the engine reaches a presetover-temperature condition, the engineswitches to alternating cylinder operation.Each disabled cylinder acts as an air pumpand cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
Continued operation increases the enginetemperature, causing the engine tocompletely shut down. Your steering andbraking effort increases in this situation.
When the engine temperature cools, youcan re-start the engine. Have your vehiclechecked as soon as possible to minimizeengine damage.
When Fail-Safe Mode Is Activated
WARNING: Fail-safe mode is foruse during emergencies only. Operateyour vehicle in fail-safe mode only aslong as necessary to bring your vehicleto rest in a safe location and seekimmediate repairs. When in fail-safemode, your vehicle will have limitedpower, will not be able to maintainhigh-speed operation, and maycompletely shut down without warning,potentially losing engine power, powersteering assist, and power brake assist,which may increase the possibility of acrash resulting in serious injury.
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
Your vehicle has limited engine powerwhen in the fail-safe mode, drive yourvehicle with caution. Your vehicle does notmaintain high-speed operation and theengine may operate poorly.
Remember that the engine is capable ofshutting down to prevent engine damage.In this situation:
1.Pull off the road as soon as safelypossible and switch the engine off.
2.If you are a member of a roadsideassistance program, we recommendthat you contact your roadsideassistance service provider.
3.If this is not possible, wait a shortperiod for the engine to cool.
4.Check the coolant level. If the coolantlevel is at or below the minimum mark,add prediluted coolant immediately.
5.When the engine temperature cools,you can re-start the engine. Have yourvehicle checked as soon as possible tominimize engine damage.
Note: Driving your vehicle without repairincreases the chance of engine damage.
Engine Coolant TemperatureManagement (If Equipped)
WARNING: To reduce the risk ofcrash and injury, be prepared that thevehicle speed may reduce and thevehicle may not be able to acceleratewith full power until the coolanttemperature reduces.
If you tow a trailer with your vehicle, theengine may temporarily reach a highertemperature during severe operatingconditions, for example ascending a longor steep grade in high ambienttemperatures.
