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.

Basic Operating Principles
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•When driving your vehicle on surfacesmade slippery by loose sand, water,gravel, snow or ice proceed with care.
•Do not use 4H or 4L on dry, hardsurfaced roads. Doing so will produceexcessive noise, increase tire wear andmay damage drive components. 4H or4L modes are only intended forconsistently slippery or loose surfaces.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce yourvehicle speed and avoid severe braking.When your vehicle speed has been reducedease your vehicle back onto the road. Donot turn the steering wheel sharply whilereturning your vehicle to the road.
It may be safer to stay on the shoulder ofthe road and slow down gradually beforereturning to the road. You may lose controlif you do not slow down or if you turn thesteering wheel too sharply or abruptly.
It may be less risky to strike small objects,such as freeway reflectors, with minordamage to your vehicle rather thanattempt a sudden return to the road whichcould cause your vehicle to slide sidewaysout of control or roll over. Remember, yoursafety and the safety of others should beyour primary concern.
Emergency Maneuvers
In an unavoidable emergency situationwhere a sudden sharp turn must be made,remember to avoid over-driving yourvehicle (i.e. turn the steering wheel only asrapidly and as far as required to avoid theemergency). Excessive steering can resultin loss of vehicle control. Apply smoothpressure to the accelerator pedal or brakepedal when changes in vehicle speed are
required. Avoid abrupt steering,acceleration and braking. This could resultin an increased risk of vehicle roll over, lossof vehicle control and personal injury. Useall available road surface to bring yourvehicle to a safe direction of travel.
In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.
If your vehicle goes from one type ofsurface to another (i.e. from concrete togravel) there will be a change in the wayyour vehicle responds to a maneuver (i.e.steering, acceleration or braking).
Sand
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Avoid reducing the tire pressures but shiftto a lower gear and drive steadily throughthe terrain. Apply the accelerator slowlyand avoid excessive wheel slip.
When driving at slow speeds in deep sandunder high outside temperatures, use a lowgear when possible. Low gear operationwill maximize the engine and transmissioncooling capability.
Avoid driving at excessive speeds, thiscauses vehicle momentum to work againstyou and your vehicle could become stuckto the point that assistance may berequired from another vehicle. Remember,you may be able to back out the way youcame if you proceed with caution.
Mud and Water
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even four-wheel drive vehicles canlose traction in slick mud. If your vehicledoes slide, steer in the direction of the slideuntil you regain control of your vehicle.

Four-Wheel Drive (If Equipped)

PRINCIPLE OF OPERATION
WARNINGS
Hill descent control cannot controldescent in all surface conditions andcircumstances, such as ice orextremely steep grades. Hill descentcontrol is a driver assist system and cannotsubstitute for good judgment by the driver.Failure to do so may result in loss of vehiclecontrol, crash or serious injury.
Hill descent control does not providehill hold at zero miles per hour (0kilometers per hour). When stopped,the parking brake must be applied or thevehicle must be placed in P (Park) or itmay roll away.
Hill descent control allows the driver to setand maintain vehicle speed whiledescending steep grades in various surfaceconditions.
Hill descent control can maintain vehiclespeeds on downhill grades between 2 mph(3 km/h) and 12 mph (20 km/h). Above 20mph (32 km/h), the system remainsarmed, but descent speed cannot be setor maintained.
Hill descent control requires a coolingdown interval after a period of sustaineduse. The amount of time that the featurecan remain active before cooling varieswith conditions. The system will provide awarning in the message center and a chimewill sound when the system is about todisengage for cooling. At this time,manually apply the brakes as needed tomaintain descent speed.
USING HILL DESCENT
CONTROL
Press and release the hilldescent button located on theinstrument panel. A light in thecluster will illuminate and a chime willsound when this feature is activated.
To increase descent speed, press theaccelerator pedal until the desired speedis reached. To decrease descent speed,press the brake pedal until the desiredspeed is reached.
Whether accelerating or decelerating, oncethe desired descent speed is reached,remove your feet from the pedals and thechosen vehicle speed will be maintained.
Note:Noise from the ABS pump motor maybe observed during hill descent controloperation. This is a normal characteristic ofthe ABS and should be no reason forconcern.
Hill descent modes
•At speeds below 20 mph (32 km/h):When the Hill Descent Control switchis pressed and Hill Descent Control isactive, the Hill Descent Control telltalewill flash.
•At speeds below 20 mph (32 km/h):When the Hill Descent Control switchis pressed and conditions are notcorrect for hill descent activation, theHill Descent Control system will beenabled, the Hill Descent Controltelltale will be solid and a message willdisplay in the information display.
•At speeds above 20 mph (32 km/h):When the Hill Descent Control switchis pressed, the Hill Descent Controlsystem will be enabled, the telltale inthe cluster will not be illuminated anda message will be displayed in theinformation display.

When Towing a Trailer
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•When stopped in congested or heavytraffic during hot weather, place thegearshift in position P to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off automaticallywhen you are towing on long, steepgrades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission is equipped with aGrade Assist or Tow/Haul feature, usethis feature when towing. This providesengine braking and helps eliminateexcessive transmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdaptive Steering and you haveenabled Tow/Haul, the AdaptiveSteering system adjusts the steeringresponse to match your vehicle’s load.The system reduces vehicle sensitivityto steering inputs at higher vehiclespeeds while it maintains the ease ofparking and maneuverability at lowspeeds.
•If your vehicle is equipped withAdvanceTrac with RSC, this systemmay turn on during typical corneringmaneuvers with a heavily loaded trailer.This is normal. Turning the corner at aslower speed while towing may reducethis tendency.
•If you are towing a trailer frequently inhot weather, hilly conditions, at thegross combined weight rating (or anycombination of these factors), considerrefilling your rear axle with syntheticgear lubricant (if the axle is not alreadyfilled with it).
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission inposition P.
4. Place wheel chocks in front and backof the trailer wheels. (Chocks notincluded with vehicle.)
Your vehicle may be equipped with atemporary or conventional spare tire. A"temporary" spare tire is different in size(diameter or width), tread-type(All-Season or All Terrain) or is from adifferent manufacturer than the road tireson your vehicle. Consult information on thetire label or Safety Compliance label forlimitations when using.
Launching or Retrieving a Boat orPersonal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbefore backing the trailer into the water.
Note:Reconnect the wiring to the trailerafter you remove the trailer from the water.
