Using Seatbelts During Pregnancy
WARNING: Always ride and drivewith your seatback upright and properlyfasten your seatbelt. Fit the lap portionof the seatbelt snugly and low acrossthe hips. Position the shoulder portion ofthe seatbelt across your chest. Pregnantwomen must follow this practice. Seethe following figure.
Pregnant women should always wear theirseatbelt. Position the lap belt portion of acombination lap and shoulder belt lowacross the hips below the belly and wornas tight as comfort allows. Position theshoulder belt to cross the middle of theshoulder and the center of the chest.
Seatbelt Locking Modes
WARNING: If your vehicle isinvolved in a crash, have the seatbeltsand associated components inspectedas soon as possible. Failure to follow thisinstruction could result in personal injuryor death.
The safety restraints in the vehicle arecombination lap and shoulder belts. Thedriver seatbelt has the first type of lockingmode. The front outboard passenger andrear outboard seat seatbelts have bothtypes of locking modes described asfollows:
Vehicle Sensitive Mode
This is the normal retractor mode, whichallows free shoulder belt lengthadjustment to your movements andlocking in response to vehicle movement.For example, if the driver brakes suddenlyor turns a corner sharply, or the vehiclereceives an impact of about 5 mph(8 km/h) or more, the combinationseatbelts will lock to help reduce forwardmovement of the driver and passengers.
In addition, the retractor is designed to lockif you pull the webbing out too quickly. Ifthe seatbelt retractor locks, slowly lowerthe height adjuster to allow the seatbeltto retract. If the retractor does not unlock,pull the seatbelt out slowly then feed asmall length of webbing back toward thestowed position. For rear seatbelts, reclinethe rear seat backrest or push the seatbackrest cushion away from the seatbelt.Feed a small length of webbing backtoward the stowed position.
Automatic Locking Mode
In this mode, the shoulder beltautomatically prelocks. The belt stillretracts to remove any slack in theshoulder belt. The automatic locking modeis not available on the driver seatbelt oroptional front center or rear centerseatbelt.

2.Put the transmission into neutral (N)and use the brakes to bring your vehicleto a safe stop.
3.When your vehicle has stopped, shiftinto park (P).
4.Apply the parking brake.
Guarding Against Exhaust Fumes
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.
Important Ventilating Information
If you stop your vehicle and leave theengine idling for long periods of time, werecommend you either open the windowsat least 1 in (3 cm) or set the climatecontrol to outside air.
STARTING A DIESEL ENGINE
Read all starting instructions carefullybefore you start your vehicle.
The 6.7L diesel engine incorporates a delaybetween a crank command and starterengagement to crank the engine. Thisdelay ensures robust starting performancein all environmental conditions includingextreme cold. The crank command isinitiated by the operator by turning theignition key. The delay varies with enginecoolant temperature. There is no delay forhot coolant temperature. The delayincreases at colder coolant temperatures.Maximum delay of 2.5 seconds isexperienced below -13.0°F (-25°C).
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, using the enginecoolant temperature, barometric pressuresensor and environmental temperaturesensor, determines how long the glowplugs stay energized. The required time forthe glow plugs to be energized decreasesas the coolant temperature, barometricpressure and environmental temperatureincrease.
Before starting the engine, check thefollowing:
•Make sure all occupants fasten theirseatbelt.
•Make sure the headlamps andelectrical accessories are off.
•Make sure the parking brake is on.
•Make sure the transmission is in park(P) or neutral (N).
•Turn the ignition key to the on position.
Note:Do not press the accelerator duringstarting.
1.Fully press the brake pedal.
2.Turn the key to the start position tostart the engine. Release the key whenthe engine starts.

Automatic Transmission AdaptiveLearning
This feature could increase durability andprovide consistent shift feel over the lifeof your vehicle. A new vehicle ortransmission may have firm shifts, softshifts, or both. This is normal and does notaffect the function or durability of thetransmission. Over time, the adaptivelearning process fully updates transmissionoperation.
Brake-Shift Interlock
WARNING: Do not drive yourvehicle until you verify that thestoplamps are working.
WARNING: When doing thisprocedure, you need to take thetransmission out of park (P) whichmeans your vehicle can roll freely. Toavoid unwanted vehicle movement,apply the parking brake prior to doingthis procedure. Use wheel chocks ifappropriate.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
Your vehicle has a brake-shift interlockfeature that prevents the gearshift leverfrom moving from park (P) when youswitch the ignition on but have not pressedthe brake pedal.
If you cannot move the gearshift lever outof the park (P) position with the ignition inthe on position and the brake pedalpressed, a malfunction could haveoccurred. It is possible that a fuse hasblown, or your vehicle’s brake lamps arenot operating properly. See FuseSpecification Chart (page 202).
If you do not have a blown fuse and thebrake lamps are working properly, thefollowing procedure allows you to movethe gearshift lever from park (P):
1.Apply the parking brake. Switch theignition key to off, then remove the key.
2.Move the steering column to the fulldown and full rearward position,toward the driver seat.
3.Remove the gearshift lever boot.
4.Place your fingers into the hole whereyou removed the gearshift lever bootand pull the top half of the shroud upand forward to separate it from thelower half of the shroud. There is ahinge at the forward edge of the top ofthe shroud. Roll the top half of theshroud upward on the hinge point, thenpull straight rearward toward the driverseat to remove.
5.Remove the top half of the shroud.
6.Remove the three fasteners under thecolumn that secure the lower shroudhalf to the column.
7.Pull the lock lever into the full unlockedposition and remove the lower shroudcover by pulling the lever handlethrough the slot in the cover.

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.
See Warning Lamps and Indicators(page 67).

2024 F-650/750 (TBC) , enUSA, Edition date: 202210, First-PrintingBrakesE67020 E210335

If the system is disabled, normalbraking is still effective. If thebrake warning lamp illuminateswith the parking brake released, have thesystem checked immediately. It alsomomentarily illuminates when you switchthe ignition on to confirm the lamp isfunctional. If it does not illuminate whenyou switch the ignition on, or begins toflash at any time, have the systemchecked.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
The anti-lock brake system does noteliminate the risks when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and may travel further.Maintain pressure on the brake pedal. Youmay also hear a noise from the system. Thisis normal.
PARKING BRAKE
Hydraulic Brakes (If Equipped)
WARNING: Always set the parkingbrake and leave your vehicle with thetransmission in park (P).
WARNING: This control is forparking only. Do not leave the vehicleunattended after setting the parkingbrake without placing the transmissionin park (P). We recommend using wheelchocks for hilly or off-roadcircumstances.
WARNING: Unexpected andpossibly sudden vehicle movement mayoccur if you do not take theseprecautions.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
Apply the parking brake whenever thevehicle is parked. To set the parking brake,pull the handle up until it snaps into thelocked position.
When the parking brake is out ofadjustment, seek service immediately.
The parking brake warning lampin the instrument clusterilluminates, and remainsilluminated (when you switch on theignition), until you release the parkingbrake.

Push the palm release lever (A) on theparking brake handle (B) and push downas far as possible to release the brake.Driving with the parking brake on causesthe brakes to wear out quickly and reducesfuel economy.
We recommend you not use the parkingbrake to stop a moving vehicle. However,if the normal brakes fail, you can use theparking brake to stop your vehicle in anemergency. Since the parking brake onlyapplies retardation to the rear wheels, thevehicle's stopping distance increasesgreatly and the handling of your vehicle isadversely affected.
Releasing Spring Manually
WARNING: Do not attempt todisassemble the parking brake airchamber under any circumstances asthis may cause serious injury.
WARNING: Block the wheels tohelp prevent the vehicle from moving.
WARNING: Unexpected andpossibly sudden vehicle movement mayoccur if you do not take theseprecautions.
If you release hydraulic pressure from thespring brake chamber, the power springapplies the brake. If the hydraulic pressurecan be re-established, you must releasethe spring brake in order to move yourvehicle.
Air Brakes (If Equipped)
WARNING: This control is forparking only. Do not leave the vehicleunattended after setting the parkingbrake without placing the transmissionin park (P). We recommend using wheelchocks for hilly or off-roadcircumstances.
If the service brakes fail to operate whileyour vehicle is moving, you can make anemergency stop with the parking brake.Since the parking brake only appliesstopping power to the rear wheels, yourvehicle’s stopping distance greatlyincreases and the handling of your vehicleis adversely affected. Make repairsimmediately to an inoperative air brakesystem circuit.
Pull the yellow, dash-mounted parkingbrake knob to apply the parking brake.
The parking brake lightilluminates and remainsilluminated (when you switchthe ignition to the on position) until yourelease the parking brake.
