ESSENTIAL TOWING CHECKS
WARNING
Do not exceed the maximumpermissible nose weight, e.g. verticalweight on the tow ball. Failure toadhere to this warning could result in lossof vehicle control, serious personal injuryor death.
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive yourvehicle at least 1,000 mi (1,600 km).
•Consult your local motor vehicle lawsfor towing a trailer.
•See the instructions included withtowing accessories for the properinstallation and adjustmentspecifications.
•Service your vehicle more frequently ifyou tow a trailer. See your scheduledmaintenance information.
•If you use a rental trailer, follow theinstructions the rental agency givesyou.
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.
Vehicles with a diesel engine have anengine braking feature. See GeneralInformation (page 221).

If this message displays, with no trailerconnected, the problem is with your vehiclewiring or trailer brake controller. Contactan authorized dealer.
If the message only displays with a trailerconnected, the problem is with the trailerwiring. Consult your trailer dealer forassistance. This can be a short to ground(such as a chaffed wire), short to voltage(such as a pulled pin on trailer emergencybreakaway battery) or the trailer brakesmay be drawing too much current.
Points to Remember
Note:Do not attempt removal of the trailerbrake controller without consulting theWorkshop Manual. Damage to the unit mayresult.
•Adjust gain setting before using thetrailer brake controller.
•Adjust gain setting, using the procedureabove, whenever road, weather, traileror vehicle loading conditions changefrom when the gain was initially set.
•Only use the manual control lever forproper adjustment of the gain duringtrailer setup. Misuse, such asapplication during trailer sway, couldcause instability of trailer or towvehicle.
•Avoid towing in adverse weatherconditions. The trailer brake controllerdoes not provide anti-lock control ofthe trailer wheels. Trailer wheels canlock up on slippery surfaces, resultingin reduced stability of trailer and towvehicle.
•The trailer brake controller is equippedwith a feature that reduces output atvehicle speeds below 11 mph (18 km/h)so trailer and vehicle braking is not jerkyor harsh. This feature is only activewhen applying the brakes using yourvehicle's brake pedal, not thecontroller.
•The controller interacts with the brakecontrol system and powertrain controlsystem of your vehicle to provide thebest performance on different roadconditions.
•Your vehicle's brake system and thetrailer brake system workindependently of each other. Changingthe gain setting on the controller doesnot affect the operation of yourvehicle's brakes.
•When you switch the engine off, thecontroller output is disabled and thedisplay and module shut down.
Trailer Lamps
WARNING
Never connect any trailer lamp wiringto the vehicle's tail lamp wiring; thismay damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
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.

Towing

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.

BREAKING-IN
You need to break in new tires forapproximately 300 mi (480 km). Duringthis time, your vehicle may exhibit someunusual driving characteristics.
Avoid driving too fast during the first1,000 mi (1,600 km). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Drive your new vehicle at least 1,000 mi(1,600 km) before towing a trailer. Makesure you use the specified engine oil. SeeCapacities and Specifications (page422).
Do not add friction modifier compoundsor special break-in oils during the first fewthousand miles (kilometers) of operation.These additives may prevent piston ringseating.
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Drive a heavily loaded vehicle or tow atrailer.
•Carry unnecessary weight(approximately 1 mpg [0.4 km/L] islost for every 400 lb [180 kilogram] ofweight carried).
•Driving with the wheels out ofalignment.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars, light bars, running boards, skiracks or luggage racks) may reducefuel economy.
•To maximize the fuel economy, drivewith the tonneau cover installed (ifequipped).
•Using fuel blended with alcohol maylower fuel economy.
292
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201710, Second Printing
Driving Hints

•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.
•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Four-wheel-drive operation (ifequipped) is less fuel efficient thantwo-wheel-drive operation.
•Close the windows for high-speeddriving.
DRIVING THROUGH WATER
WARNING
Do not drive through flowing or deepwater as you may lose control of yourvehicle.
Note:Driving through standing water cancause vehicle damage.
Note:Engine damage can occur if waterenters the air filter.
Before driving through standing water,check the depth. Never drive through waterthat is higher than the bottom of the wheelhubs.

•Headlight aim may requirere-adjustment.
•The tire air pressures recommendedfor general driving are on the vehicle’sSafety Certification Label. Themaximum cold inflation pressure forthe tire and associated load rating ison the tire sidewall. Tire air pressuremay require re-adjustment within thesepressure limits to accommodate theadditional weight of the snowplowinstallation.
•Federal and some local regulationsrequire additional exterior lamps forsnowplow-equipped vehicles. Consultyour authorized dealer for additionalinformation.
Operating the Vehicle with theSnowplow Attached
Note:Do not use your vehicle for snowremoval until you have driven at least500 mi (800 km).
Ford recommends vehicle speed does notexceed 45 mph (72 km/h) whensnowplowing.
The attached snowplow blade restrictsairflow to the radiator, and may cause theengine to run at a higher temperature:Attention to engine temperature isespecially important when outsidetemperatures are above freezing. Anglethe blade to maximize airflow to theradiator and monitor engine temperatureto determine whether a left or right angleprovides the best performance.
Follow the severe duty schedule in yourScheduled Maintenance information forengine oil and transmission fluid changeintervals.
Snowplowing with your AirbagEquipped Vehicle
WARNINGS
Do not attempt to service, repair, ormodify the airbag supplementalrestraint system (SRS) or its fuses.Contact an authorized dealer.
