PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involvingbraking system, aftermarket roofracks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronic stabilitycontrol system. In addition, installing anystereo loudspeakers may interfere withand adversely affect the electronic stabilitycontrol system. Install any aftermarketstereo loudspeaker as far as possible fromthe front center console, the tunnel, andthe front seats in order to minimize the riskof interfering with the electronic stabilitycontrol sensors. Reducing theeffectiveness of the electronic stabilitycontrol system could lead to an increasedrisk of loss of vehicle control, vehiclerollover, personal injury and death.
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicleincreasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip the road;this could reduce the operator’s ability tocontrol the vehicle potentially resulting ina loss of vehicle control, vehicle rollover,personal injury and death. If your electronicstability control system activates, SLOWDOWN.
The system automatically turns on eachtime you switch the ignition on.
If a fault occurs in either the stabilitycontrol or the traction control system, youmay experience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal may move as the system applieshigher brake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
The system enhances your vehicle’s abilityto prevent skids or lateral slides byapplying brakes to one or more of thewheels individually and, if necessary,reducing engine power.
Roll Stability Control
The system enhances your vehicle’s abilityto prevent rollovers by detecting yourvehicle’s roll motion and the rate at whichit changes by applying the brakes to oneor more wheels individually.

Stability Control

•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 removing the trailer from the water.
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 inches (15 centimeters) abovethe bottom edge of the rear bumper.
Exceeding these limits may allow water toenter vehicle components:
•Causing internal damage to thecomponents.
•Affecting driveability, emissions, andreliability.
Replace the rear axle lubricant anytimethe rear axle has been submerged in water.Water may have contaminated the rearaxle lubricant, which is not normallychecked or changed unless a leak issuspected or other axle repair is required.
TOWING POINTS (If Equipped)
WARNINGS
Using recovery hooks is dangerousand should only be done by a personfamiliar with proper vehicle recoverysafety practices. Improper use of recoveryhooks may cause hook failure or separationfrom the vehicle and could result in seriousinjury or death.
Always slowly remove the slack fromthe recovery strap prior to pulling.Failure to do so can introducesignificantly higher loads which can causethe recovery hooks to break off, or therecovery strap to fail which can causeserious injury or death.
Never link two straps together witha clevis pin. These heavy metalobjects could become projectiles ifthe strap breaks and can cause seriousinjury or death.
Your vehicle comes equipped withframe-mounted front recovery hooks.These hooks should never have a loadapplied to them greater than the grossvehicle weight rating of your vehicle.

Towing

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).
REDUCED ENGINE
PERFORMANCE
WARNING
Continued operation will increase theengine temperature and cause theengine to shut down completely.
If the engine coolant temperature gaugeneedle moves to the upper limit position,the engine is overheating. See Gauges(page 84).
You must only drive your vehicle for a shortdistance if the engine overheats. Thedistance you can travel depends onambient temperature, vehicle load andterrain. The engine will continue to operatewith limited power for a short time.
If the engine temperature continues to rise,the fuel supply to the engine will reduce.The air conditioning will switch off and theengine cooling fan will operate continually.
1.Reduce your speed gradually and stopyour vehicle as soon as it is safe to doso.
2. Switch the engine off immediately toprevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See EngineCoolant Check (page 247).
5. Have your vehicle checked by anauthorized dealer as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several thingssuch as how you drive, the conditions youdrive under and how you maintain yourvehicle.
There are some things to keep in mind thatmay improve your fuel economy:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving (When runningerrands, go to the furthest destinationfirst and then work your way backhome).
•Close the windows for high-speeddriving.
•Drive at reasonable speeds.
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
There are also some things you may wantto avoid doing because they reduce yourfuel economy:
•Avoid sudden or hard accelerations.
•Avoid revving the engine before turningoff the car.
•Avoid long idle periods.
•Do not warm up your vehicle on coldmornings.
•Reduce the use of air conditioning andheat.

Driving Hints

You should:
•Remove dust and loose dirt with avacuum cleaner.
•Clean and treat spills and stains assoon as possible.
Do not use the following products as thesemay damage the leather:
•Oil and petroleum or silicone-basedleather conditioners.
•Household cleaners.
•Alcohol solutions.
•Solvents or cleaners intendedspecifically for rubber, vinyl andplastics.
With King Ranch Edition
Your vehicle has seating covered inpremium, top-grain leather that isextremely durable, but still requires specialcare and maintenance in order to preservelongevity and comfort.
Regular cleaning and conditioningmaintains the appearance of the leather.
Cleaning
For dirt, use a vacuum cleaner then use aclean, damp cloth or soft brush.
For routine cleaning, wipe the surface witha soft, damp cloth. For more thoroughcleaning, wipe the surface with a mild soapand water solution.
•Clean spills as quickly as possible.
•Test any cleaner or stain remover onan inconspicuous part of the leather ascleaners may darken the leather.
•Do not spill coffee, ketchup, mustard,orange juice or oil-based products onthe leather as they may permanentlystain the leather.
•Do not use household cleaningproducts, alcohol solutions, solventsor cleaners intended for rubber, vinylor plastics.
Scratches
Because the leather in the seat comesfrom genuine steer hides, there may beevidence of naturally occurring markings,such as small scars. These markings givecharacter to the seating covers and areconsidered to be proof of a genuine leatherproduct.
In order to lessen the appearance ofcertain scratches and other wear marks,apply conditioner on the affected areafollowing the same instructions as in theConditioning section.
Conditioning
Bottles of King Ranch Leather Conditionerare available at the King Ranch SaddleShop. Visit the website atwww.krsaddleshop.com, or call1–800–282–KING (5464) in the UnitedStates. If you are unable to obtain KingRanch Leather Conditioner, use anotherpremium leather conditioner.
•Clean the surfaces using the stepsoutlined in the Cleaning section.
•Make sure the leather is dry then applya nickel-sized amount of conditionerto a clean, dry cloth.
•Rub the conditioner into the leatheruntil it disappears. Allow theconditioner to dry, then repeat theprocess for the entire interior. If a filmappears, wipe it off with a dry, cleancloth.

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 276).
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.
Four-wheel drive system (If Equipped)
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 165). For information ontransfer case maintenance, SeeMaintenance (page 243). 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 (page165).
How your vehicle differs fromother vehicles

Wheels and Tires

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 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.
