CLEANING THE EXHAUST -
6.7L DIESEL
WARNINGS
Failure to maintain the functionalholes, in the tailpipe section of theexhaust, clean and free of debris orforeign material may result in the holesbecoming blocked or plugged. Do notmodify or remove the tail-pipe section.Blocked or plugged holes orremoval/modification of the system couldresult in elevated exhaust gastemperatures which may result invehicle/property damage or personalinjury.
The normal operating temperatureof the exhaust system is very high.Never work around or attempt torepair any part of the exhaust system untilit has cooled. Use special care whenworking around the diesel oxidationcatalytic converter and/or the dieselparticulate filter (DPF). The dieseloxidation catalytic converter and/or theDPF heats up to a high temperature afteronly a short period of engine operation andcan stay hot even after the engine is turnedoff. Failure to follow these instructions mayresult in personal injury.
The visible holes in the exhaust tip and theholes under the shield just inboard of theright rear tire(s) are functional. The holesneed to be kept clear of mud/debris orforeign material to maintain properfunction of the exhaust system. Clean andremove debris or foreign material if presentas needed. Spraying with a hose duringregular washing of vehicle should helpkeep holes clean and clear of debris orforeign material.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmentalfallout can result in windshield and wiperblade contamination. Dirty windshield andwipers will result in poor windshield wiperoperation. Keep the windshield and wiperblades clean to maintain windshield wiperperformance.

Vehicle Care

GENERAL INFORMATION
Use only approved wheel and tire sizes,using other sizes could damage yourvehicle. If you change the diameter of thetires from that fitted at the factory, thespeedometer may not display the correctspeed. Take your vehicle to an authorizedFord dealer to have the systemreprogrammed. If you intend to change thesize of the wheels from that fitted by themanufacturer, you can check the suitabilitywith an authorized dealer.
Additional information related to thefunctionality and maintenance of your tirescan be found later in this chapter. See TireCare (page 377).
The Ford recommended tire inflationpressures can be found on the Tire Label,which is located on the B-pillar or the edgeof the driver's door. This information canalso be found on the Safety ComplianceCertification Label (affixed to either thedoor hinge pillar, door-latch post, or thedoor edge that meets the door last post;next to the driver’s seating position).
Ford strongly recommends maintainingthese tire pressures at all times. Failure tofollow the tire pressure recommendationscan cause uneven treadwear patterns,reduced fuel economy, and adverselyaffect the way your vehicle handles.
Note:Check and set the tire pressure at theambient temperature in which you areintending to drive your vehicle and when thetires are cold.
Note:Check your tire pressures at leastonce per month.
Set the pressure for your spare tire to thehighest value given for your vehicle and tiresize combination (if equipped).
Notice to utility vehicle and truckowners
WARNINGS
Utility vehicles have a significantlyhigher rollover rate than other typesof vehicles. To reduce the risk ofserious injury or death from a rollover orother crash you must avoid sharp turns andabrupt maneuvers, drive at safe speeds forthe conditions, keep tires inflated to Fordrecommended pressures, never overloador improperly load your vehicle, and makesure every passenger is properly restrained.
In a rollover crash, an unbeltedperson is significantly more likely todie than a person wearing a seat belt.All occupants must wear seat belts andchildren/infants must use appropriaterestraints to minimize the risk of injury orejection.
Do not become overconfident in theability of four-wheel drive vehicles.Although a four-wheel drive vehiclemay accelerate better than a two-wheeldrive vehicle in low traction situations, itwon't stop any faster than two-wheel drivevehicles. Always drive at a safe speed.

Utility vehicles and trucks handledifferently than passenger cars in thevarious driving conditions that areencountered on streets, highways andoff-road. Utility vehicles and trucks are notdesigned for cornering at speeds as highas passenger cars any more than low-slungsports cars are designed to performsatisfactorily under off-road conditions.
Study your owner's manual and anysupplements for specific information aboutequipment features, instructions for safedriving and additional precautions toreduce the risk of an accident or seriousinjury.

WARNING
Do not become overconfident in theability of four-wheel drive vehicles.Although a four-wheel drive vehiclemay accelerate better than a two-wheeldrive vehicle in low traction situations, itwon't stop any faster than two-wheel drivevehicles. Always drive at a safe speed.
A vehicle equipped with four-wheel drive(when selected) has the ability to use allfour wheels to power itself. This increasestraction which may enable you to safelydrive over terrain and road conditions thata conventional two-wheel drive vehiclecannot.
Power is supplied to all four wheelsthrough a transfer case or power transferunit. Four-wheel drive vehicles allow youto select different modes as necessary. Forinformation on transfer case operation andshifting procedures, See Four-WheelDrive (page 210). For information ontransfer case maintenance, SeeMaintenance (page 322). You shouldbecome thoroughly familiar with thisinformation before you operate yourvehicle.
On some four-wheel drive vehicles, theinitial shift from two-wheel to four-wheeldrive while the vehicle is moving can causea momentary clunk and ratcheting sound.These sounds are normal and are notcause for concern.
For four-wheel drive vehicles, a spare tireof a different size other than the tireprovided should never be used. A dissimilarspare tire size (other than the spare tireprovided) or major dissimilar tire sizedbetween the front and rear axles couldcause the four-wheel drive system to stopfunctioning and default to front-wheeldrive. See Using Four-Wheel Drive (page210).

TIRE CARE
Information About UniformTire Quality Grading
Tire Quality Grades apply to newpneumatic passenger car tires.The Quality grades can be foundwhere applicable on the tiresidewall between tread shoulderand maximum section width. Forexample: Treadwear 200Traction AA Temperature A.
These Tire Quality Grades aredetermined by standards that theUnited States Department ofTransportation has set.
Tire Quality Grades apply to newpneumatic passenger car tires.They do not apply to deep tread,winter-type snow tires,space-saver or temporary usespare tires, light truck or LT typetires, tires with nominal rimdiameters of 10 to 12 inches orlimited production tires as definedin Title 49 Code of FederalRegulations Part 575.104 ©)(2).
U.S. Department ofTransportation Tire qualitygrades: The U.S. Department ofTransportation requires FordMotor Company to give you thefollowing information about tiregrades exactly as the governmenthas written it.
Treadwear
The treadwear grade is acomparative rating based on thewear rate of the tire when testedunder controlled conditions on aspecified government test course.For example, a tire graded 150would wear one and one-half (1½) times as well on thegovernment course as a tiregraded 100. The relativeperformance of tires depends
upon the actual conditions of theiruse, however, and may departsignificantly from the norm due tovariations in driving habits, servicepractices, and differences in roadcharacteristics and climate.
Traction AA A B C
WARNING
The traction grade assignedto this tire is based onstraight-ahead braking tractiontests, and does not includeacceleration, cornering,hydroplaning or peak tractioncharacteristics.
377
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201710, Second Printing
Wheels and TiresE142542

The traction grades, from highestto lowest are AA, A, B, and C. Thegrades represent the tire’s abilityto stop on wet pavement asmeasured under controlledconditions on specifiedgovernment test surfaces ofasphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING
The temperature grade forthis tire is established for atire that is properly inflated andnot overloaded. Excessive speed,underinflation, or excessiveloading, either separately or incombination, can cause heat
buildup and possible tire failure.
The temperature grades are A(the highest), B and C,representing the tire’s resistanceto the generation of heat and itsability to dissipate heat whentested under controlled conditionson a specified indoor laboratorytest wheel. Sustained hightemperature can cause thematerial of the tire to degenerateand reduce tire life, and excessivetemperature can lead to suddentire failure. The grade Ccorresponds to a level ofperformance which all passengercar tires must meet under the
Federal Motor Vehicle SafetyStandard No. 139. Grades B and Arepresent higher levels ofperformance on the laboratorytest wheel than the minimumrequired by law.
Glossary of Tire Terminology
*Tire label: A label showing theoriginal equipment tire sizes,recommended inflation pressureand the maximum weight thevehicle can carry.
*Tire Identification Number(TIN): A number on the sidewallof each tire providing informationabout the tire brand andmanufacturing plant, tire size anddate of manufacture. Also referredto as DOT code.
*Inflation pressure: A measureof the amount of air in a tire.
*Standard load: A class ofP-metric or Metric tires designedto carry a maximum load at setpressure. For example: ForP-metric tires 35 psi (2.4 bar) andfor Metric tires 36 psi (2.5 bar).Increasing the inflation pressurebeyond this pressure will notincrease the tire’s load carryingcapability.
*Extra load: A class of P-metricor Metric tires designed to carry aheavier maximum load at 42 psi(2.9 bar). Increasing the inflationpressure beyond this pressure willnot increase the tire’s loadcarrying capability.

*Temperature: The temperaturegrades are A (the highest), B andC, representing the tire'sresistance to the generation ofheat and its ability to dissipateheat when tested under controlledconditions on a specified indoorlaboratory test wheel.
M.Maximum InflationPressure: Indicates the tiremanufacturers' maximumpermissible pressure or thepressure at which the maximumload can be carried by the tire. Thispressure is normally higher thanthe vehicle manufacturer'srecommended cold inflationpressure which can be found onthe Safety ComplianceCertification Label (affixed toeither the door hinge pillar,door-latch post, or the door edgethat meets the door-latch post,next to the driver's seatingposition), or Tire Label located onthe B-pillar or the edge of thedriver's door. The cold inflationpressure should never be set lowerthan the recommended pressureon the vehicle label.
The tire suppliers may haveadditional markings, notes orwarnings such as standard loador radial tubeless.

Inflating Your Tires
Safe operation of your vehiclerequires that your tires areproperly inflated. Remember thata tire can lose up to half of its airpressure without appearing flat.
Every day before you drive, checkyour tires. If one looks lower thanthe others, use a tire gauge tocheck pressure of all tires andadjust if required.
At least once a month and beforelong trips, inspect each tire andcheck the tire pressure with a tiregauge (including spare, ifequipped). Inflate all tires to theinflation pressure recommendedby Ford Motor Company.
You are strongly urged to buy areliable tire pressure gauge, asautomatic service station gaugesmay be inaccurate. Fordrecommends the use of a digitalor dial-type tire pressure gaugerather than a stick-type tirepressure gauge.
Use the recommended coldinflation pressure for optimum tireperformance and wear.Under-inflation or over-inflationmay cause uneven treadwearpatterns.
WARNING
Under-inflation is the mostcommon cause of tire failuresand may result in severe tirecracking, tread separation orblowout, with unexpected loss ofvehicle control and increased riskof injury. Under-inflation increasessidewall flexing and rollingresistance, resulting in heatbuildup and internal damage tothe tire. It also may result inunnecessary tire stress, irregularwear, loss of vehicle control andaccidents. A tire can lose up tohalf of its air pressure and notappear to be flat!
Always inflate your tires to theFord recommended inflationpressure even if it is less than themaximum inflation pressureinformation found on the tire. TheFord recommended tire inflationpressure is found on the SafetyCompliance Certification Label orTire Label (affixed to either thedoor hinge pillar, door-latch post,or the door edge that meets thedoor-latch post, next to thedriver's seating position), or TireLabel located on the B-pillar orthe edge of the driver's door.Failure to follow the tire pressurerecommendations can causeuneven treadwear patterns andadversely affect the way yourvehicle handles.

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. For example, during

any procedure involving tireinflation, the technician orindividual must utilize a remoteinflation device, and ensure thatall persons are clear of thetrajectory area.
WARNING
Always inflate steel carcasstires with a remote air fill withthe person inflating standing at aminimum of 12 ft (3.66 m) awayfrom the wheel and tire assembly.
Inspecting Your Tires andWheel Valve Stems
Periodically inspect the tire treadsfor uneven or excessive wear andremove objects such as stones,nails or glass that may be wedgedin the tread grooves. Check the tireand valve stems for holes, cracks,or cuts that may permit air
leakage and repair or replace thetire and replace the valve stem.Inspect the tire sidewalls forcracking, cuts, bruises and othersigns of damage or excessivewear. If internal damage to the tireis suspected, have the tiredemounted and inspected in case
