2017 FORD F250 SUPER DUTY fuel

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.

Towing

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.

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.
When driving through standing water, drivevery slowly and do not stop your vehicle.Your brake performance and traction maybe limited. After driving through water andas soon as it is safe to do so:
•Lightly press the brake pedal to dry thebrakes and to check that they work.
•Check that the horn works.
•Check that the exterior lights work.
•Turn the steering wheel to check thatthe steering power assist works.
FLOOR MATS
WARNINGS

Onlyuse floor mats that are firmly secured toretention posts so that they cannot slip outof position and interfere with the pedalsor impair safe operation of your vehicle inother ways.
Pedals that cannot move freely cancause loss of vehicle control andincrease the risk of serious personalinjury.
Always make sure that the floormats are properly attached to theretention posts in the carpet that aresupplied with your vehicle. Floor mats mustbe properly secured to both retention poststo make sure mats do not shift out ofposition.
Never place floor mats or any othercovering in the vehicle foot well thatcannot be properly secured toprevent them from moving and interferingwith the pedals or the ability to control thevehicle.
