PRINCIPLE OF OPERATION
The traction control system helps avoiddrive wheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheelsand, when needed, reduces engine powerat the same time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL -
VEHICLES WITH: AIR BRAKES
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
Press the TCS Off button on theinstrument panel to enable themud/snow mode.
This is beneficial when your vehicle is stuckin snow or on a slippery road surface. Thismode allows wheel spin to dig your vehicleout and allows you to rock your vehicle.
Press the switch again to select standardtraction control. The system automaticallyselects standard traction control at thenext ignition cycle.
System Indicator Light
Note:If the traction control light does notflash during a traction control event or staysilluminated, the system is not functioningproperly. Take your vehicle to an authorizeddealer for service.
During traction control operation, thetraction control light flashes rapidly andthe engine does not rev-up when you pressfurther on the accelerator. This is normaland is no reason for concern.
In mud/snow mode, the TCS OFF lightilluminates on the instrument cluster. If atraction event occurs in either mode, thestability and traction control light flashesrapidly.
USING TRACTION CONTROL -
VEHICLES WITH: HYDRAULIC
BRAKES
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system turns on each time you switchthe ignition on.
Use the traction control buttonon the instrument panel toswitch the system off or on.
If your vehicle is stuck in mud or snow,switching traction control off is beneficialas this allows the wheels to spin.
Press the button again to switch thetraction control system on.
System Indicator Light
Note:If the traction control light does notflash during a traction control event or stayson, the system is not operating. Have thesystem checked as soon as possible.

ESSENTIAL TOWING CHECKS
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.
Remember to account for the trailertongue weight as part of your vehicle loadwhen calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps ontothe bumper or attaches to the axle. Youmust distribute the load in your trailer sothat 10-15% of the total weight of thetrailer is on the tongue.
Safety Chains
Note:Do not attach safety chains to thebumper.
Always connect the safety chains to theframe or hook retainers of your vehiclehitch.
To connect the safety chains, cross thechains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.
Trailer Brakes
WARNING: Do not connect atrailer's hydraulic brake system directlyto your vehicle's brake system. Yourvehicle may not have enough brakingpower and your chances of having acollision greatly increase.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Trailer Lamps
WARNING: Never connect anytrailer lamp wiring to the vehicle's taillamp wiring; this may damage theelectrical system resulting in fire. Contactyour authorized dealer as soon aspossible for assistance in proper trailertow wiring installation. Additionalelectrical equipment may be required.
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.
When Towing a Trailer
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mph(80 km/h).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) or neutral (N)to aid engine and transmission coolingand to help air conditioningperformance.
•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 withthe Tow/Haul feature, use this featurewhen towing. This provides enginebraking and helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•Allow more distance for stopping witha trailer attached. Anticipate stops andbrake gradually.
FIFTH WHEEL OPERATION (IF
EQUIPPED)
WARNING: Failure to follow thefifth wheel manufacturer’s instructionsfor hooking and unhooking as well assliding the fifth wheel could result in anaccident, personal injury or death.
WARNING: When the tractor andtrailer are parked unattended, the trailerbrake hand control should never be usedto apply the brake, since air may leakfrom the system, allowing vehiclemovement, resulting in possible propertydamage, personal injury or death.
Before hook-up, make sure:
•The fifth wheel jaws are fully open.
•The fifth wheel is fully tilted back toprevent body damage when the tractoris backed under a trailer.
•You block the trailer wheels and adjustand apply the trailer spring brakes.Never chase a trailer.
•The brake hoses and light cords areclear of the fifth wheel.
Hook-up
1.Back the tractor squarely under thetrailer, engaging the fifth-wheel jawson the kingpin. Always back up slowly;make sure the trailer is neither too highnor too low. Avoid backing under thetrailer from an angle.
2.Connect the service and emergencybrake hoses and trailer light connector.
3.Inspect the jaws of the fifth wheel tobe sure they have fully closed on thetrailer kingpin and the trailer plate isresting securely on the fifth wheel.
4.Make sure the coupler release lever isin the locked position.
5.Charge the trailer brake system. Setthe trailer brakes, with either the handvalve or tractor protection valve. Pullagainst the trailer for an extra check ofproper hook-up. Do not pull hardenough to damage or strain theequipment.
6.Set the tractor parking brakes and fullyraise the trailer landing gear.
7.Check the operation of all trailer lightsand correct any lights that may befaulty.
Un-hook
1.Try to keep the tractor and trailer in astraight line.
2.Apply the parking brakes.
3.Lower the trailer landing gear, makingsure it is on solid, level ground. Theweight of the trailer is to be on thelanding gear.
4.Block the trailer wheels.

DRIVING THROUGH WATER
WARNING: Do not drive throughflowing or deep water as you may losecontrol of your vehicle.
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.
Operation in Standing Water
Ingestion of water into the diesel enginecan result in immediate and severedamage to the engine. If driving throughwater, slow down to avoid splashing waterinto the intake. If the engine stalls, and yoususpect ingestion of water into the engine,do not try to restart the engine. Consultyour dealer for service immediately.
Your fuel tank vents to the atmosphere byvalves on top of the tank and through thefuel cap. If water reaches the top of thetank, the valves may pull water into thefuel tank. Water in the fuel can causeperformance issues and damage the fuelinjection system.

ENGINE COOLANT CHECK -
6.7L DIESEL
WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: To reduce the risk ofpersonal injury, make sure the engine iscool before unscrewing the coolantpressure relief cap. The cooling systemis under pressure. Steam and hot liquidcan come out forcefully when you loosenthe cap slightly.
When the engine is cold, check theconcentration and level of the coolant atthe intervals listed in the scheduledmaintenance information. See ScheduledMaintenance (page 325).
Note:Make sure that the coolant level isbetween the MIN and the MAX marks onthe coolant reservoir.
Note: Coolant expands when it is hot. Thelevel may extend beyond the MAX mark.
Maintain coolant concentration within48% to 50%, which equates to a freezepoint between -30°F (-34°C) and -34°F(-37°C). Coolant concentration should bechecked using a refractometer. We do notrecommend the use of hydrometers orcoolant test strips for measuring coolantconcentration.
Adding Coolant
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.

Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle warranty.
It is very important to use predilutedcoolant approved to the correctspecification to avoid plugging the smallpassageways in the engine cooling system.See Cooling System Capacity andSpecification (page 301). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and maynot be covered by the vehicle warranty.
Note: Coolants marketed for all makes andmodels may not be approved to Fordspecifications and may cause damage tothe cooling system. Resulting componentdamage may not be covered by the vehicleWarranty.
If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
For vehicles with overflow coolant systemswith a non-pressurized cap on the coolantrecovery system, add coolant to thecoolant recovery reservoir when the engineis cool. Add prediluted coolant to themaximum level. For all vehicles which havea coolant degas system with a pressurizedcap, or if it is necessary to remove thecoolant pressure relief cap on the radiator,follow these steps to add engine coolant:
1.Turn the engine off and let it cool.
2.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
3.Fill the coolant reservoir slowly withprediluted engine coolant to within theminimum and maximum range on theengine coolant reservoir. If youremoved the radiator cap in anoverflow system, fill the radiator until
the coolant is visible and the radiatoris almost full. If coolant is added tobring the level within the minimum andmaximum range when the engine is notcold, the system may remain underfilled.
4.Replace the coolant reservoir cap, turnit clockwise until you feel a strongresistance.
5.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, add enoughprediluted engine coolant to bring thecoolant level to the proper level.
Note:If prediluted coolant is not available,use the approved antifreeze concentratediluting it to 50/50 with distilled water. SeeCooling System Capacity andSpecification (page 301). Using water thathas not been deionized may contribute todeposit formation, corrosion or plugging ofthe small cooling system passageways.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
Note:During normal vehicle operation, thecoolant may change color from orange topink or light red. As long as the coolant isclear and uncontaminated, this color changedoes not indicate the coolant has degradednor does it require the coolant to be drained,the system to be flushed, or the coolant tobe replaced.
In case of emergency, you can add a largeamount of water without predilutedcoolant to reach a vehicle service location.On arrival do the following:
1.Drain the cooling system.
2.Chemically clean the cooling system.We recommend Motorcraft PremiumCooling System Flush.

When you reach a servicelocation, you must have the cooling systemdrained, flushed and refilled using thecorrect specification prediluted coolant orantifreeze concentrate. See CoolingSystem Capacity and Specification (page302).
Do not use the following as a coolantsubstitute:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Alcohol and other liquids can cause enginedamage from overheating or freezing.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
