Emission Control System Laws
WARNING
Do not remove or alter the originalequipment floor covering orinsulation between it and the metalfloor of the vehicle. The floor covering andinsulation protect occupants of the vehiclefrom the engine and exhaust system heatand noise. On vehicles with no originalequipment floor covering insulation, do notcarry passengers in a manner that permitsprolonged skin contact with the metalfloor. Failure to follow these instructionsmay result in fire or personal injury.
In the United States, federal law andcertain state laws prohibit removing orrendering the emission control systeminoperative. Similar federal or provinciallaws may apply in Canada. We do notrecommend any vehicle modificationwithout determining applicable law.
Tampering with emissionscontrol system, including relatedsensors or the diesel exhaustfluid injection system can result in reducedengine power and the service engine soonwarning lamp illuminating in theinformation display.
Tampering with a Noise ControlSystem
Federal law prohibits the following acts orthe causing thereof:
•The removal or rendering inoperativeby any person other than for purposesof maintenance, repair or replacementof any device or element of designincorporated into any new vehicle forthe purpose of noise control prior to itssale or delivery to the ultimatepurchaser or while it is in use.
•The use of the vehicle after such deviceor element of design has been removedor rendered inoperative by any person.
Among those acts, which the United StatesEnvironmental Protection Agency maypresume to constitute tampering are theacts listed below:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturer’sspecifications.

Putting your vehicle in or out of gear:
1. Fully press down the brake pedal.
2. Move the gearshift lever into thedesired gear.
3. Come to a complete stop.
4. Move the gearshift lever and securelylatch it in park (P).
Park (P)
This position locks the transmission andprevents the rear wheels from turning.
Reverse (R)
With the gearshift lever in reverse (R), yourvehicle will move backward. Always cometo a complete stop before shifting into andout of reverse (R).
Neutral (N)
With the gearshift lever in neutral (N), yourvehicle can be started and is free to roll.Hold the brake pedal down while in thisposition.
Drive (D)
Drive (D) is the normal driving position forthe best fuel economy. The drive functionallows automatic upshifts and downshiftsthrough gears one through six.
M (Manual)
With the gearshift lever in manual (M), thedriver can change gears up or down asdesired. By moving the gearshift lever fromdrive position drive (D) to manual (M) younow have control of selecting the gear youdesire using buttons on the shift lever. SeeUnderstanding your SelectShiftAutomatic™ transmission later in thissection.
To return to normal drive (D) position,move the shift lever back from manual (M)to drive (D).
The transmission operates in gears onethrough six.

Forced downshifts
•Allowed in drive (D) with the tow/haulfeature on or off.
•Press the accelerator to the floor.
•Allows transmission to select anappropriate gear.
Tow/Haul Mode
WARNING
Do not use the tow/haul featurewhen driving in icy or slipperyconditions as the increased enginebraking can cause the rear wheels to slideand your vehicle to swing around with thepossible loss of vehicle control.
To activate tow/haul, press thebutton on the gearshift leveronce. The TOW HAUL indicatorlight illuminates in the instrument cluster.
The tow/haul feature:
•Delays upshifts to reduce the frequencyof transmission shifting.
•Provides engine braking in all forwardgears, which slows your vehicle andassists you in controlling your vehiclewhen descending a grade.
•Depending on driving conditions andload conditions, may downshift thetransmission, slow your vehicle andcontrol your vehicle speed whendescending a hill, without pressing theaccelerator pedal. The amount ofdownshift braking provided will varybased upon the amount you press thebrake pedal.
The tow/haul feature improvestransmission operation when towing atrailer or a heavy load. All transmissiongear ranges are available when usingtow/haul.
Note:If your vehicle is equipped with theAdaptive Steering System, enabling thetow/haul feature will adjust the steeringresponse. In tow/haul mode the AdaptiveSteering system reduces vehicle sensitivityto steering inputs at higher vehicle speedswhile maintaining the ease of parking andmaneuverability at low speeds. SeeSteering (page 256).
To deactivate the tow/haul feature andreturn to normal driving mode, press thebutton on the gearshift lever whentow/haul is active. The TOW HAUL lightdeactivates. Tow/haul also deactivateswhen you power down your vehicle.

Automatic Transmission AdaptiveLearning
This feature's design is to increasedurability and provide consistent shift feelover the life of your vehicle. A new vehicleor transmission may have firm shifts, softshifts or both. This operation is normal anddoes not affect function or durability of thetransmission. Over time, the adaptivelearning process fully updates transmissionoperation. Additionally, whenever youdisconnect the battery or install a newbattery, the system must relearn thestrategy.
Brake-Shift Interlock
WARNINGS
Do not drive your vehicle until youverify that the brake lamps areworking.
When doing this procedure, you needto take the transmission out of park(P) which means your vehicle canroll freely. To avoid unwanted vehiclemovement, always fully apply the parkingbrake prior to doing this procedure. Usewheels chocks if appropriate.
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. Have your vehiclechecked as soon as possible.
Your vehicle is equipped with a brake-shiftinterlock feature that prevents thegearshift lever from moving from park (P)when the ignition is on and the brake pedalis not pressed.
If you cannot move the gearshift lever outof park (P) position with the ignition is onand the brake pedal pressed, a malfunctionmay have occurred. It is possible that afuse has blown or your vehicle’s brakelamps are not operating properly. SeeFuse Specification Chart (page 312).
If the fuse is not blown and the brakelamps are working properly, the followingprocedure allows you to move the gearshiftlever from park (P):
1. Apply the parking brake. Switch theignition key to 1 (off), then remove thekey.
2. Move the steering column to the fulldown and full rearward position(toward the driver’s seat).
3. Remove the gearshift lever boot.
4. Place fingers into hole where youremoved the gearshift lever boot andpull top half of shroud up and forwardto separate it from the lower half of theshroud. There is a hinge at the forwardedge of the top shroud. Roll the tophalf of the shroud upward on the hingepoint to clear the hazard flasher button,then pull straight rearward toward thedriver’s seat 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.
8.Apply the brake. Gently lift the overridedisk and move the gearshift lever intoneutral (N).

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 may occur.
Note:Do not rock your vehicle for morethan a minute or damage to thetransmission and tires may occur, or theengine may overheat.
If your vehicle is stuck in mud or snow, youmay rock it out by shifting between forwardand reverse gears, stopping between shiftsin a steady pattern. Press lightly on theaccelerator in each gear.
POWER TAKE-OFF
WARNING
Use of auxiliary equipment thatexceeds the maximum PowerTake-Off (PTO) load specified in theFord Truck Body Builders Layout Book canadversely affect the performance of thepowertrain system. Refer to the BodyBuilders Layout Book for instructions aboutthe appropriate installation of additionalequipment.
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 thevehicle is stationary. In this condition, thereis limited cooling air flow through theradiator and around the vehicle thatnormally occurs when a vehicle is moving.The aftermarket PTO system installer,having the most knowledge of the finalapplication, is responsible for determiningwhether additional chassis heat protectionor powertrain cooling is required, andalerting the user to the safe and properoperation.
Ford Super Duty Vehicles are approved foruse as a stationary (including split shaftcapability) or mobile power source, withinlimits and operating guidelines detailed inthe Ford Truck Body Builders Layout Book,found at www.fleet.ford.com/truckbbas,and through the Ford Truck Body BuildersAdvisory Service.

If Shift Delayed Pull Forward appears inthe information display, transfer case geartooth blockage is present. To alleviate thiscondition, place the transmission in aforward gear, move the vehicle forwardapproximately 5 ft (1.5 m), and shift thetransmission back to neutral to allow thetransfer case to complete the range shift.
How Your Vehicle Differs FromOther Vehicles
WARNING
Vehicles with a higher center ofgravity (utility and four-wheel drivevehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injury anddeath.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle may behigher to allow it to travel over roughterrain without getting hung up ordamaging underbody components.
The differences that make your vehicle soversatile also make it handle differentlythan an ordinary passenger car.
Maintain steering wheel control at alltimes, especially in rough terrain. Sincesudden changes in terrain can result inabrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes.
Drive cautiously to avoid vehicle damagefrom concealed objects such as rocks andstumps.
You should either know the terrain orexamine maps of the area before driving.Map out your route before driving in thearea. To maintain steering and brakingcontrol of your vehicle, you must have allfour wheels on the ground and they mustbe rolling, not sliding or spinning.
Driving Off-Road With Truck andUtility Vehicles
Note:On some models, the initial shift fromtwo-wheel drive to four-wheel drive whilethe vehicle is moving can cause somemomentary clunk and ratcheting sounds.This is the front drivetrain coming up tospeed and the automatic locking hubsengaging and is not cause for concern.
Note:Your vehicle may be equipped witha front air dam that can become damaged(due to reduced ground clearance) whentaking your vehicle off-road. This air damcan be taken off by removing 15 bolts.
Four-wheel drive vehicles are speciallyequipped for driving on sand, snow, mudand rough terrain and have operatingcharacteristics that are somewhatdifferent from conventional vehicles, bothon and off the road.
Power is supplied to all four wheelsthrough a transfer case. On four-wheeldrive vehicles, the transfer case allows youto select 4WD when necessary.Information on transfer case operation andshifting procedures can be found in thischapter. Information on transfer casemaintenance can be found in theMaintenance chapter. You should becomethoroughly familiar with this informationbefore you operate your vehicle.
Four-wheel drive (when you select a 4WDmode) uses all four wheels to power thevehicle. This increases traction, enablingyou to drive over terrain and roadconditions that a conventional two-wheeldrive vehicle cannot.

Driving on Snow and Ice
WARNING
If you are driving in slipperyconditions that require tire chains orcables, then it is critical that you drivecautiously. Keep speeds down, allow forlonger stopping distances and avoidaggressive steering to reduce the chancesof a loss of vehicle control which can leadto serious injury or death. If the rear end ofyour vehicle slides while cornering, steer inthe direction of the slide until you regaincontrol of your vehicle.
Note:Excessive tire slippage can causetransmission damage.
Four-wheel drive vehicles have advantagesover two-wheel drive vehicles in snow andice but can skid like any other vehicle.Should you start to slide while driving onsnowy or icy roads, turn the steering wheelin the direction of the slide until you regaincontrol.
Avoid sudden applications of power andquick changes of direction on snow andice. Apply the accelerator slowly andsteadily when starting from a full stop.
Avoid sudden braking. Although afour-wheel drive vehicle may acceleratebetter than a two-wheel drive vehicle insnow and ice, it will not stop any faster asbraking occurs at all four wheels. Do notbecome overconfident as to roadconditions.
Make sure you allow sufficient distancebetween you and other vehicles forstopping. Drive slower than usual andconsider using one of the lower gears. Inemergency stopping situations, apply thebrake steadily. Do not pump the brakepedal. See Hints on Driving WithAnti-Lock Brakes (page 222).
If Your Vehicle Gets Stuck In Mud orSnow
WARNING
Do not spin the wheels at over34 mph (55 km/h). The tires may failand injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,it may be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature,damage to the transmission may occur.
Note:Do not rock your vehicle for morethan a minute, damage to the transmissionand tires may occur or the engine mayoverheat.
Parking
WARNINGS
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not beworking properly. Have your vehiclechecked as soon as possible.
Always set the parking brake andleave your vehicle with thetransmission in park (P).
On some four-wheel drive vehicles, whenthe transfer case is in the N (Neutral)position, the engine and transmission aredisconnected from the rest of the driveline.Therefore, the vehicle is free to roll even ifthe automatic transmission is in P (Park)or the manual transmission is in gear. Donot leave the vehicle unattended with thetransfer case in the N (Neutral) position.Always set the parking brake fully and turnoff the ignition when leaving the vehicle.

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 by an authorized dealer. Ifyour vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 370).
See Warning Lamps andIndicators (page 105).
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.
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.
Brake Assist
Brake assist detects when you brakerapidly by measuring the rate at which youpress the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal, and can reduce stoppingdistances in critical situations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarilyilluminates when you switch theignition on. If the light does notilluminate during start up, remains on orflashes, the system may be disabled. Havethe system checked by an authorizeddealer. If the anti-lock brake system isdisabled, normal braking is still effective.
If the brake warning lampremains illuminated after yourelease the parking brake, havethe system checked by an authorizeddealer.
Diesel Engine Braking (If Equipped)
WARNING
Do not use tow/haul or enginebraking when driving in icy or slipperyconditions as the increased brakingcan cause the rear wheels to slide and yourvehicle to swing around with the possibleloss of vehicle control.
This feature increases engine braking athigher engine speeds to provide bettergrade descent control with less brake andtransmission wear and tear. It alsoimproves engine braking when towing orcarrying heavy loads.
Press the button on the switchbank next to the audio unit toswitch the system on or off.
There are two engine brake modes, manualand automatic.
