2016 FORD F450 SUPER DUTY run flat

Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1000 miles (1600 kilometers) ofdriving (this is your engine’s break-inperiod); a more accurate measurement isobtained after 2000 miles - 3000 miles(3200 kilometers - 4800 kilometers). Also,fuel expense, frequency of fill ups or fuelgauge readings are not accurate ways tomeasure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2. Each time you fill the tank, record theamount of fuel added.
3.After at least 3 to 5 tank fill ups, fill thefuel tank and record the currentodometer reading.
4. Subtract your initial odometer readingfrom the current odometer reading.
5. Calculate fuel economy by dividingmiles traveled by gallons used (ForMetric: Multiply liters used by 100, thendivide by kilometers traveled).
Keep a record for at least 1 month andrecord the type of driving (city or highway).This provides an accurate estimate of thevehicle’s fuel economy under currentdriving conditions. Additionally, keepingrecords during summer and winter showhow temperature impacts fuel economy.In general, lower temperatures mean lowerfuel economy.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Carrying unnecessary weight mayreduce fuel economy (approximately1 mpg [0.4 km/L] is lost for every 400pounds [180 kilograms] of weightcarried).
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars/light bars, running boards, skiracks) may reduce fuel economy.
•Using fuel blended with alcohol maylower fuel economy.
•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.
•Close windows for high speed driving.
EMISSION CONTROL SYSTEM
WARNINGS
Do not park, idle, or drive your vehiclein dry grass or other dry ground cover.The emission system heats up theengine compartment and exhaust system,which can start a fire.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your dealer inspect yourvehicle immediately. Do not drive if yousmell exhaust fumes.

Fuel and Refueling

STEERING
To help prevent damage to the powersteering system:
•Never hold the steering wheel at itsfurthest turning points (until it stops)for more than three to five secondswhen the engine is running.
•Do not operate the vehicle with a lowpower steering pump fluid level (belowthe MIN mark on the reservoir).
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks down(or if the engine is turned off), you cansteer the vehicle manually, but it takesmore effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper vehicle alignment
If any steering components are serviced orreplaced, install new fasteners (many arecoated with thread adhesive or haveprevailing torque features which may notbe re-used). Never re-use a bolt or nut.Torque fasteners to specifications.
A high crown in the road or high crosswindsmay also make the steering seem towander or pull.

Driving Aids

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
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.
•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.

Driving Hints

•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.
Additional equipment such assnowplow equipment may affect theperformance of the airbag sensorsincreasing the risk of injury. Please refer tothe Body Builders Layout Book forinstructions about the appropriateinstallation of additional equipment.
All occupants of the vehicle,including the driver, should alwaysproperly wear their safety belts, evenwhen provided with an airbagsupplemental restraint system (SRS).
Your vehicle is equipped with a driver andpassenger airbag supplemental restraintsystem. The supplemental restraint systemwill activate in certain frontal and offsetfrontal collisions when the vehicle sustainssufficient frontal deceleration.
Careless or high speed driving whileplowing snow that results in sufficientvehicle decelerations can deploy theairbag. Such driving also increases the riskof accidents
Never remove or defeat the trippingmechanisms designed into the snowremoval equipment by its manufacturer.Doing so may cause damage to the vehicleand the snow removal equipment as wellas possible airbag deployment.
Engine temperature while plowing
When driving with a plow, your engine mayrun at a higher temperature than normalbecause the attached snowplow blade willrestrict airflow to the radiator.

Driving Hints

Note:If you have to drive adistance to get air for your tire(s),check and record the tire pressurefirst and add the appropriate airpressure when you get to thepump. It is normal for tires to heatup and the air pressure inside to goup as you drive.
2. Remove the cap from the valveon one tire, then firmly press thetire gauge onto the valve andmeasure the pressure.
3. Add enough air to reach therecommended air pressure.
Note:If you overfill the tire, releaseair by pressing on the metal stemin the center of the valve. Thenrecheck the pressure with your tiregauge.
4. Replace the valve cap.
5. Repeat this procedure for eachtire, including the spare.
Note:Some spare tires operate ata higher inflation pressure than theother tires. For T type mini-sparetires, (see the Dissimilar sparewheel and tire assemblyinformation for a description. Storeand maintain at 60 psi (4.15 bar).For full-size and dissimilar sparetires, see the Dissimilar spare wheeland tire assembly information fora description. Store and maintainat the higher of the front and rearinflation pressure as shown on theSafety Compliance CertificationLabel or Tire Label.
6. Visually inspect the tires tomake sure there are no nails orother objects embedded thatcould poke a hole in the tire andcause an air leak.
7. Check the sidewalls to makesure there are no gouges, cuts orbulges.
Tire Inflation Information
WARNING
An inflated tire and rim canbe very dangerous ifimproperly used, serviced ormaintained. To reduce the risk ofserious injury, never attempt tore-inflate a tire which has been runflat or seriously under-inflatedwithout first removing the tire
from the wheel assembly forinspection. Do not attempt to addair to tires or replace tires orwheels without first takingprecautions to protect personsand property.
All tires with Steel Carcass Plies(if equipped):
This type of tire utilizes steel cordsin the sidewalls. As such, theycannot be treated like normal lighttruck tires. Tire service, includingadjusting tire pressure, must beperformed by personnel trained,supervised and equippedaccording to Federal OccupationalSafety and Health Administrationregulations.

Wheels and Tires

*Avoid fast starts, stops and turns.
*Avoid potholes and objects onthe road.
*Do not run over curbs or hit thetire against a curb when parking.
Highway Hazards
No matter how carefully you drivethere’s always the possibility thatyou may eventually have a flat tireon the highway. Drive slowly to theclosest safe area out of traffic.This may further damage the flattire, but your safety is moreimportant.
If you feel a sudden vibration orride disturbance while driving, oryou suspect your tire or vehiclehas been damaged, immediately
reduce your speed. Drive withcaution until you can safely pulloff the road. Stop and inspect thetires for damage. If a tire isunder-inflated or damaged,deflate it, remove wheel andreplace it with your spare tire andwheel. If you cannot detect acause, have the vehicle towed tothe nearest repair facility or tiredealer to have the vehicleinspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb orpothole can cause the front endof your vehicle to becomemisaligned or cause damage toyour tires. If your vehicle seems topull to one side when you’redriving, the wheels may be out ofalignment. Have an authorizeddealer check the wheel alignmentperiodically.
Wheel misalignment in the frontor the rear can cause uneven andrapid treadwear of your tires andshould be corrected by anauthorized dealer. Front-wheeldrive vehicles and those with anindependent rear suspension mayrequire alignment of all fourwheels.
The tires should also be balancedperiodically. An unbalanced tireand wheel assembly may result inirregular tire wear.
Tire Rotation
WARNING
If the tire label showsdifferent tire pressures for thefront and rear tires and the vehicleis equipped with a tire pressuremonitoring system, then thesettings for the system sensorsneed to be updated. Alwaysperform the system resetprocedure after tire rotation. If thesystem is not reset, it may notprovide a low tire pressurewarning when necessary.
