vehicle.

Engine

Ensure the hood prop rod is in place before performing maintenance or inspections in the engine compartment.

Failure to comply could result in personal injury.

Engine will become hot during normal operation. Allow engine to completely cool before performing maintenance

or inspections. Failure to comply could result in burn injury.

Stay clear of moving parts. Be sure to wear eye protection, long sleeves or a shop coat while performing engine

maintenance or inspection. Failure to comply could result in personal injury.

Battery

Conrm main power and all other electrical components are o before performing maintenance on batteries or

electrical system. Failure to comply could result in equipment damage.

Do not make contact between terminals. Do not wear jewelry while performing maintenance on batteries. Always

disconnect the ground and the negative terminals rst and re-connect last. Failure to comply could result in

equipment damage, electrical shock, or re hazard.

Always wear face and skin protection i.e. goggles and long sleeves.

Engine Coolant

Wait een minutes aer vehicle operation to remove the coolant reservoir cap. Using a heavy rag, turn radiator

cap ¼ to ½ of a turn to allow pressure to escape from radiator.

Ensure all personnel are clear of radiator and radiator fans while engine is running. Failure to comply could result

in injury to personnel.

Wear safety goggles and work gloves while servicing coolant system. Label all connections before removing any

parts. Failure to comply could result in equipment damage or personal injury.

Fuel

Do not ll fuel tank while engine is running, do not over ll tank, and make sure fuel nozzle is grounded to ller

neck to prevent sparks while fueling.

Be alert at all times for the smell of fuel while operating vehicle. If fuel smell is detected shut down engine

immediately.

Clean up all fuel spills, as they can create a re and slip hazard. Dispose of materials in accordance with local

hazardous waste disposal procedures.

Fuel is highly ammable and can explode. Keep open ames, sparks and other ignition sources away from diesel

fuel and have a re extinguisher at hand. Do not smoke while working with fuel; do not work on fuel system while

engine is hot. Fuel can be ignited by a hot engine.

Transmission

Transmission becomes hot during normal operation. When performing maintenance on transmission wear safety

goggles, work gloves, and protective clothing to avoid injury. Avoid contact with hot transmission oil while draining

transmission oil. Failure to comply could result in burn injury.

Transfer Case

Transfer case and oil cooler become very hot during normal operation. Allow transfer case and oil cooler to cool

before servicing. Wear safety goggles, work gloves and protective clothing. Extreme caution should be used while

opening drain valves and removing bolts. Failure to comply could result in burn injury.

Engine Fluids

Oil, Fuel, and coolant may be hazardous to the environment and to human health. Become familiar with MSDS’s

(Material Safety Data Sheets). Handle all uids and other contaminated material (Filters, Rags) in accordance with

standard operating procedures. Recycle or dispose of engine uids/lters and other contaminated materials in

accordance with standard operating procedures.

Refrigerant

e temperature of R-134a refrigerant is -20 Degrees Fahrenheit (-29 Degrees Celsius). Wear a full face shield,

protective rubberized gloves, and protective clothing when working with refrigerants. Contact your safety

personnel for appropriate safety precautions while handling refrigerants.

Do not expose refrigerant containers empty or full to open ames or temperatures above 125 Degrees Fahrenheit

(52 Degrees Celsius). Do not discard empty containers where they are subject to heat from a trash burner; containers

may explode. Failure to comply may result in equipment failure or personal injury.

Refrigerant may become poisonous in the presence of heat. Do not smoke or allow any type of ame in the

immediate area while servicing air conditioning system. Never weld, solder, steam clean or use excessive heat on

any part of the air conditioning system while charged or pressurized.

R134a must not be mixed with air before being pressurized. When mixed with large quantities of air and pressurized

R134a becomes combustible.

Refrigerant evaporates quickly and can displace oxygen in the work area, and can cause suocation. If a leak occurs

avoid breathing refrigerant vapor and thoroughly ventilate work area before continuing service to HVAC system.

Federal and state laws require that refrigerant be recovered and recycled. Refrigerant must be recovered from

system with authorized recommended equipment before any work can be performed on the unit. Always use

approved recycling equipment to prevent accidental discharge.

Do not use parts other than those specied for the system being serviced.

Accidental and intentional introduction of liquid contaminants to the environment is a violation of State, Federal,

and Military regulations. Store, install, and dispose of containers in accordance with standard operating procedures.

Carbon Monoxide

Carbon Monoxide is a dangerous gas that deprives the body of oxygen and causes suocation. Carbon Monoxide is

colorless and odorless, but can be detected with a carbon monoxide detector. To avoid carbon monoxide poisoning

follow these precautions:

• Do not let engine idle for long periods of time. If it is necessary to the run engine indoors during vehicle

maintenance use proper ventilation equipment to exhaust gases outside

• Do not operate personnel heater in enclosed area without proper ventilation

• Do not sleep in vehicle with heater on or engine idling

• Notify Fleet Maintenance if exhaust fumes are detected in crew compartment of vehicle while operating

Be aware at all times for exhaust odors and signs of exposure to carbon monoxide such as headache, dizziness,

and loss of muscular control, apparent drowsiness, and coma. Contact your safety personnel for appropriate safety

precautions when in contact with carbon monoxide.

Brakes

Use Tow/Haul for constant stop and go, short haul, and steep grade operation.

Do not park vehicle on longitudinal slopes greater than 30 Degrees.

Wheels and Tires

If tire air pressure is lost do not exceed 25MPH while driving on Run Flats.

Wheel and tire assemblies are heavy; do not attempt to li wheel or tire assemblies without assistance. Be sure to

wear the appropriate PPE while working on wheel assemblies.

Ensure vehicle is parked on a at level surface before removing Wheel/Tire assemblies. So or uneven ground

could result in jack or jack stands sinking.

Jacks / Liing

Before liing the vehicle, make sure it is parked on a level surface. Put the vehicle in park, set the emergency brake,

and chock the wheels. Use hydraulic jack rated for 6 ton or more.

Never work under a vehicle supported by only a jack or liing device. Use properly rated jack stands under frame

rails to properly support vehicle components during removal and installation procedures.

Towing

If brakes of disabled vehicle are inoperable do not at tow. Request support from a at bed or a wrecker. Do not

move towing vehicle without a ground guide. Ground guide should be in clear view at all times. Conrm that all

personnel are clear of vehicles before removing wheel chocks.

Maximum o road towing speed should not exceed 15MPH (24KM/PH). Terrain and weather conditions may

require further reduced speeds. On paved roads speeds up to 25MPH can be accomplished if conditions permit.

Prior to removing tow bar, or straps, park vehicle on level ground with wheels chocked.

Never attach safety chains or straps to axles or suspension components that have been damaged or compromised.

Vehicles with catastrophic axle or suspension damage may require the axle to be properly secured to the chassis

for safe recovery of the vehicle.

Doors

e doors are heavy; verify nobody is standing directly behind the doors before opening and closing.

Keep hands and feet clear before closing doors. Use extra caution when vehicle is on an incline.

Driving and Operating

Adjust mirrors properly prior to operation to allow for maximum eld of view.

Use ground guides in low visibility situations. Be sure ground guides remain clear of the vehicle path and remain

in clear view of the driver. Failure to comply may result in vehicle collision or injury to personnel.

Operator should visually check interior and exterior of vehicle for personnel before moving.

Do not exceed the recommended crew capacity for your specic vehicle layout.

Ensure tires are inated to proper pressure. Failure to do so could result in tire failure which could lead to an

accident.

Do not drive the vehicle more than 25 miles or at speeds over 25 MPH when operating on a at tire with Run Flat

inserts. Failure to comply could result in loss of vehicle control.

Vehicle has a 30 degree roll over angle. Sharp turns and other maneuvers should be taken cautiously. Adjust

driving style to operating conditions. Avoid side slopes, always approach slopes head on when possible.

Avoid driving or parking on so shoulders. So road shoulders can collapse. Vehicle can roll over causing severe

injury or death to personnel.

Wear restraint harnesses during vehicle operation. Check harnesses for damage before using. Adjust restraint

harnesses properly for maximum protection.

Fording Water

Do not attempt to ford water deeper than 32 inches. Ensure the ground underwater is rm to avoid sinking.

Reduce speed before entering water. Unless absolutely necessary, do not stop while driving through water.

Be sure brakes are functioning properly before commencing normal driving aer fording water.

Stowage / Cargo

Stow equipment based on a load plan. Do not block re extinguishers or vehicle exit points with equipment or

cargo.

Gunner Hatch / Stand

Be sure gunner stand is locked at a predetermined height before operation out of the hatch.

Make sure lock pins are secure before using. Before lowering gunner stand into the stowed position check for

obstructions below the stand. Check to make sure all personnel are clear of gunner stand while lowering into the

stowed position.

Before moving the vehicle with the hatch in the open position verify the hatch lid is completely locked in the open

position.

Use extreme caution when standing in the gunner position while vehicle is in motion. Operator should be holding

onto supports to maintain stability at all times.

General Vehicle Operation

Restraint Systems

Front Air Bags

Warning: Never place your arm or any objects over an airbag module. Placing your arm over a deploying

airbag can result in serious arm fractures or other injuries. Objects placed on or over the airbag ination area

may cause those objects to be propelled by the airbag into your face and torso causing serious injury.

e front passenger airbag on/o switch activates an illuminated light indicating the airbag status. e indicator

light is located to the right of the climate controls, and stays on when the airbag switch has been moved to the o

position.

Note: e passenger airbag status indicator OFF lamp will illuminate for a short period of time when the ignition is

rst turned on to conrm it is functional.

Turning the Passenger Airbag OFF

e airbag ON/OFF Switch is located on the driver’s side of the center console and is controlled using the ignition

key.

1. Insert the ignition key, turn the switch to OFF and hold in OFF while removing the key.

2. When the ignition is turned on, the “PASS AIRBAG OFF” light illuminates briey, then momentarily shuts o

and turns back on. is indicates that the passenger airbag is deactivated.

Warning: If the light fails to illuminate when the passenger air bag switch is o and the ignition is on, have the

passenger air bag switch serviced at your authorized dealer immediately. In order to avoid inadvertent

activation of the switch, always remove the ignition key from the passenger air bag on and o switch.

3. e passenger airbag remains o until you turn it back on.

Turning the Passenger Airbag Back ON

1. Insert the ignition key and turn the switch to ON.

2. e PASS AIRBAG OFF light will briey illuminate when the ignition is turned to on. is indicates that the

passenger airbag is operational.

e passenger side airbag should always be on (the PASS AIRBAG OFF light should not be illuminated) unless the

passenger is a person who meets the requirements stated either in Category 1, 2 or 3 of the National Highway Trac

Safety Administration or Transport Canada deactivation criteria. e vast majority of drivers and passengers are

much safer with an airbag than without. To do their job and reduce the risk of life threatening injuries, airbags must

open with great force, and this force can pose a potentially deadly risk in some situations, particularly when a front

seat occupant is not properly buckled up. e most eective way to reduce the risk of unnecessary airbag injuries

without reducing the overall safety of the vehicle is to make sure occupants in the front of the vehicle are properly

restrained. is provides the protection of safety belts and permits the airbags to provide the additional protection

they were designed to provide. If you choose to deactivate your airbag, you are losing the very signicant risk

reducing benets of the airbag and you are also reducing the eectiveness of the safety belts, because safety belts

in modern vehicles are designed to work as a safety system with the airbags.

Front Seats

When you use them properly, the seat, head restraint, safety belt and air bags will provide optimum protection in

the event of a crash.

Follow these guidelines:

• Ensure you are sitting in an upright position with the base of your spine as far back as possible

• Do not recline the seat back more than 30 degrees

• Keep sucient distance between yourself and the steering wheel. It is recommend a minimum of 10 inches (25

centimeters) between your breastbone and the air bag cover

• Hold the steering wheel with your arms slightly bent

• Bend your legs slightly so that you can press the pedals fully

• Position the lap belts across your hips and position the shoulder strap over the center of your shoulder. Make sure

that your driving position is comfortable and that you can maintain full control of your vehicle

Adjusting the Front Seats

Adjusting the seat base forward or backwards

1. Locate the seat adjust lever on the front of the seat base.

2. Pull the lever to the side.

3. Position the seat to its proper position by sliding it forward or backwards.

4. Release the seat adjust lever and slide the seat forward or backwards to ensure seat lock is secure.

Adjusting the back of the seat

1. Locate the knob on the le hand side of the seat.

2. Turn the knob forward to bring the back rest forward or turn the knob backwards to recline the seat.

Adjusting the Steering Wheel

Seat restraints with visible abrasion or

tearing must be replaced. Cut the old belt

in half, and discard so it cannot be used

again. Cuts, tears and other damage to the

belt will greatly reduce its eectiveness,

may cause it to fail, and may result in severe

injury or death.

Warning: Do not adjust the steering wheel while vehicle is moving.

1. Unlock the steering column.

2. Adjust the steering wheel to the desired position up/down in/out.

3. Lock the steering column.

Engine Oil Pressure Gauge

Engine Oil Pressure Gauge indicates engine oil pressure. e needle should stay in the normal operating range

(centered between L and H). If the needle falls below the normal range, stop the vehicle, turn o the engine and

check the engine oil level. Add oil if needed. If the oil level is correct, have your vehicle checked by your authorized

dealer.

Engine Coolant Temperature Gauge

Engine Coolant Temperature Gauge indicates engine coolant temperature. At normal operating temperature, the

level indicator will be in the normal range. If the engine coolant temperature exceeds the normal range, stop the

vehicle as soon as safely possible, switch o the engine and let the engine cool.

Warning: Never remove the coolant reservoir cap while the engine is running or hot.

Transmission Fluid Temperature Gauge

Transmission Fluid Temperature Gauge indicates transmission uid temperature. At normal operating temperature,

the level indicator will be in the normal range. If the transmission uid temperature exceeds the normal range,

stop the vehicle as soon as safely possible and verify that airow is not restricted such as snow or debris blocking

airow through the grill. Higher than normal operating temperature can also be caused by special operation

conditions (i.e. Towing or o-road use). Operating the transmission with the temperature in the higher than

normal range can cause transmission damage. Altering the severity of the driving conditions is recommended to

lower the transmission temperature into the normal range. If the gauge continues to show high temperatures, see

your authorized dealer.

Fuel Gauge

Note: e fuel gauge may vary slightly when your vehicle is moving or on a gradient.

Switch the ignition on. e fuel gauge will indicate approximately how much fuel is le in the fuel tank. e arrow

adjacent to the fuel pump symbol indicates on which side of your vehicle the fuel ller door is located. e needle

should move toward F when you refuel your vehicle. If the needle points to E aer adding fuel, this indicates your

vehicle needs service.

Aer refueling some variability in needle position is normal.

• It may take a short time for the needle to reach F aer fueling. is is normal and depends upon the slope of

pavement at the fueling station.

• e fuel amount dispensed into the tank is a little less or more than the gauge indicated. is is normal and

depends upon the slope of pavement at the fueling station.

• If the fuel station nozzle shuts o before the tank is full, try a dierent fuel pump nozzle.

Speedometer

e Speedometer displays the speed of the vehicle in MPH (Miles per Hour) and KPH (Kilometers per Hour). e

Speedometer is calibrated in accordance to the tire size.

Information Display

e Information Display can be used to control various systems on the vehicle using the information display

controls on the steering wheel. (See Page 89 in the Ford Owner’s Manual for more information).

Tachometer

e Tachometer shows the engine RPM’s (Revolutions per Minute).

Boost Gauge

e Boost Gauge displays pounds of boost being produce by the turbo charger.

Starting and Stopping (6.7L V8 Diesel)

Note: Make sure you are sitting in the correct position before adjusting steering wheel.

Read all starting instructions thoroughly before attempting to start the vehicle.

Before starting the engine on the vehicle make sure all occupants have fastened their seat belts. Make sure the head

lamps and electrical accessories are o. Apply the parking brake. Be sure the gearshi lever is in P (Park).

Turn the ignition key to the start position. e glow plug pre-heat indicator will illuminate in the dash.

Do not turn the key to the start position until the glow plug pre-heat indicator turns o. When the glow

plug pre-heat indicator turns o, turn the key to the start position and release the key as soon as the

engine starts. If the vehicle does not start aer the glow plug activation time ends, you may need to reset the glow

plugs by turning the key to the o position and back to run, in order to cycle the glow plugs again.

Aer the engine starts, allow it to idle for 15 seconds before driving in order to protect the engine.

Note: Make sure all auxiliary switches and interior lights are o before starting the vehicle.

Note: Do not press the accelerator during starting.

Note: Do not crank the engine for more than 10 seconds as starter damage may occur. If the engine fails to start, turn

the key to the o position and wait 30 seconds before attempting to start again.

Warning: Do not use starting uid, such as ether; in the air intake system (See air lter decal) such uid could

result in immediate explosive damage to the engine and possible personal injury.

Warning: Do not add gasoline, gasohol, alcohol, or kerosene to diesel fuel. is practice creates a serious re

hazard and causes engine performance problems.

Switching O the Engine (6.7L V8 Diesel)

Turn the ignition to the o position. To prolong engine life (especially aer extended high speed, high ambient

temperature, or high GVW/GCW operation, such as heavy loads or heavy trailers), it is recommended that a hot

engine be idled for 3-5 minutes. is allows the turbocharged engine to cool down. For more information on

GVW/GCW, see the Load Carrying chapter in your OEM Owner’s Manual.

Starting and Stopping (6.8L V10 Gasoline)

Read all starting instructions thoroughly before attempting to start the vehicle.

Before starting the engine on the vehicle make sure all occupants have fastened their seat belts. Make sure the head

lamps and electrical accessories are o. Apply the parking brake. Be sure the gearshi lever is in P (Park).

Turn the ignition key to the start position.

Aer the engine starts, allow it to idle for 15 seconds before driving in order to protect the engine.

Note: Make sure all auxiliary switches and interior lights are o before starting the vehicle.

Note: Do not press the accelerator during starting.

Note: Do not crank the engine for more than 10 seconds as starter damage may occur. If the engine fails to start, turn

the key to the o position and wait 30 seconds before attempting to start again.

Warning: Do not use starting uid, such as ether; in the air intake system such uid could result in immediate

explosive damage to the engine and possible personal injury.

Cold Weather Operation (6.7L V8 Diesel)

e use of the factory engine block heater assists in engine starting in extreme cold ambient temperatures. e

engine block heater plug is located behind the front bumper on the passenger side frame rail.

Note: e heater is most eective when outdoor temperatures are below 0°F (-18°C).

e heater acts as a starting aid by warming the engine coolant. is allows the climate control system to respond

quickly. e equipment includes a heater element (installed in the engine block) and a wire harness. You can

connect the system to a grounded 120-volt AC electrical source.

• Use a 16-gauge outdoor extension cord that is product certied by Underwriter’s Laboratory (UL) or Canadian

Standards Association (CSA). is extension cord must be suitable for use outdoors, in cold temperatures, and be

clearly marked Suitable for Use with Outdoor Appliances.

• Use as short of an extension cord as possible

• Do not use multiple extension cords

• To avoid electrical shock or re make sure that the extension cord plug and heater cord plugs are free and clear

of water

• Make sure your vehicle is parked in a clean area, clear of combustibles

• Make sure the heater cord and extension cords are rmly connected

• Check for heat anywhere in the electrical hookup once the system has been operating for approximately 30

minutes

• Make sure the system is unplugged and properly stowed before driving your vehicle. Make sure the protective

cover seals the prongs of the block heater cord plug when not in use.

• Make sure the heater system is checked for proper operation before winter. Make sure the receptacle terminals

are clean and dry prior to use. Clean them with a dry cloth if necessary.

e heater uses 0.4 to 1.0 kilowatt-hours of energy per hour of use. e system does not have a thermostat. It

achieves maximum temperature aer approximately three hours of operation. Using the heater longer than three

hours does not improve system performance and unnecessarily uses electricity.

Your vehicle is equipped with a fuel and water separator that recirculates fuel from the engine to help prevent

fuel lter clogging. To avoid engine fuel starvation during cold weather operation of 32°F (0°C) or below, the

manufacturer recommends that the fuel level in your tank should not drop below 1⁄4 full. is helps prevent air

from entering the fuel system and stalling the engine.

In cold weather below 32°F (0°C), the engine may slowly increase to a higher idle speed if le idling in P (Park)

due to the engine warming. As the engine warms up, the engine sound level decreases due to the activation of PCM

controlled sound reduction features.

If you operate your vehicle in a heavy snowstorm or blowing snow conditions, snow and ice can clog the engine

air induction. If this occurs, the engine may experience a signicant reduction in power output. At the earliest

opportunity, clear all the snow and/or ice away from inside the air lter assembly. Remove the air cleaner cover

and the pleated paper lter, leaving the foam lter in and remove any snow or ice. Make sure you install the foam

lter correctly in place. Remove any debris, snow or ice on the foam lter by brushing the surface with a so brush.

Once you have cleared all of the debris, reinstall the air lter and assembly.

Note: Do not use water, solvents, or hard brushes to clean the air lter.

Warning: To reduce the risk of vehicle damage and/or personal burn injuries do not start your engine with the

air lter removed and do not remove it while the engine is running.

In order to operate the engine in temperatures of 32°F (0°C) or lower, read the following instructions:

• Make sure that the batteries are of sucient size and are fully charged. Check other electrical components to

make sure they are in optimum condition

• Use the proper coolant solution at the concentration recommended protecting the engine against damage from

freezing

• Refuel tank at the end of operation to prevent condensation in the fuel system

• Make sure you use proper cold weather engine oil and that it is at its proper level. Also, if necessary, make sure to

follow the engine oil and lter change schedule listed in the scheduled maintenance information

• At temperatures of -10°F (-23°C) or below, it is recommended that you use an engine block heater to improve

cold engine starting

If operating in arctic temperatures of -20°F (-29°C) or lower, consult your truck dealer for information about

special cold weather equipment and precautions. e following cold weather idling guidelines are recommended:

• You can use Motorcra® cetane improvers or non-alcohol-based cetane improvers from a reputable manufacturer

as needed

• Maintain the engine cooling system properly

• Avoid shutting the engine down aer an extensive idling period. Drive your vehicle for several miles with the

engine at normal operating temperatures under a moderate load

• For extended idle times in low ambient temperatures use an approved idle speed increase device. See Stationary

Elevated Idle Control page 31.
