USING ALL-WHEEL DRIVE
All-wheel drive uses all four wheels to powerthe vehicle. This increases traction, enablingyou to drive over terrain and road conditionsthat a conventional two-wheel drive vehiclecannot. The AWD system is active all the timeand requires no input from the operator.
Note:Your AWD vehicle is not intended foroff-road use. The AWD feature gives yourvehicle some limited off-road capabilities inwhich driving surfaces are relatively level,obstruction-free and otherwise similar tonormal on-road driving conditions. Operatingyour vehicle under other than thoseconditions could subject the vehicle toexcessive stress which might result indamage which is not covered under yourwarranty.
Note:A warning message will be displayedin the information display when an AWDsystem fault is present See InformationMessages (page 125). An AWD system faultwill cause the AWD system to default tofront-wheel drive only mode. When thiswarning message is displayed, have yourvehicle serviced at an authorized dealer
Note:A warning message will be displayedin the information display if the AWD systemhas overheated See Information Messages(page 125). This condition may occur if thevehicle was operated in extreme conditionswith excessive wheel slip, such as deepsand. To resume normal AWD function assoon as possible, stop the vehicle in a safelocation and stop the engine for at least 10minutes. After the engine has been restartedand the AWD system has adequately cooled,the warning message will turn off and normalAWD function will return.
Do not use a spare tire of a different sizeother than the tire provided. If the mini-sparetire is installed, the AWD system may disableautomatically and enter front-wheel driveonly mode to protect driveline components.This condition will be indicated by a warningin the information display See InformationMessages (page 125). If there is a warningmessage in the information display fromusing the spare tire, this indicator should turnoff after reinstalling the repaired or replacednormal road tire and cycling the ignition offand on. It is recommended to reinstall the
repaired or replaced road tire as soon aspossible. Major dissimilar tire sizes betweenthe front and rear axles could cause the AWDsystem to stop functioning and default tofront-wheel drive or damage the AWDsystem.
Driving In Special Conditions With All-Wheel Drive (AWD)
AWD vehicles are equipped for driving onsand, snow, mud and rough roads and haveoperating characteristics that are somewhatdifferent from conventional vehicles, both onand off the highway.
Under severe operating conditions, the A/Cmay cycle on and off to protect overheatingof the engine.
Basic operating principles in specialconditions
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•Be extremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving brakingsystem, aftermarket roof racks,suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stability controlsystem. In addition, installing any stereoloudspeakers may interfere with andadversely affect the electronic stabilitycontrol system. Install any aftermarket stereoloudspeaker as far as possible from the frontcenter console, the tunnel, and the frontseats in order to minimize the risk ofinterfering with the electronic stability controlsensors. Reducing the effectiveness of theelectronic stability control system could leadto an increased risk of loss of vehicle control,vehicle rollover, personal injury and death.
WARNINGS
Remember that even advancedtechnology cannot defy the laws ofphysics. It’s always possible to lose controlof a vehicle due to inappropriate driver inputfor the conditions. Aggressive driving on anyroad condition can cause you to lose controlof your vehicle increasing the risk of personalinjury or property damage. Activation of theelectronic stability control system is anindication that at least some of the tires haveexceeded their ability to grip the road; thiscould reduce the operator’s ability to controlthe vehicle potentially resulting in a loss ofvehicle control, vehicle rollover, personalinjury and death. If your electronic stabilitycontrol system activates, SLOW DOWN.
The system automatically turns on each timeyou switch the ignition on.
If a fault occurs in either the stability controlor the traction control system, you mayexperience the following conditions:
•The stability and traction control lightilluminates steadily.
•The stability control and traction controlsystems do not enhance your vehicle'sability to maintain traction of the wheels.
If a driving condition activates either thestability control or the traction control systemyou may experience the following conditions:
•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 and yourfoot is not on the brake, the brake pedalmay move as the system applies higherbrake force.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:

USING ADAPTIVE CRUISE
CONTROL (If Equipped)
WARNINGS
Always pay close attention to changingroad conditions when using adaptivecruise control. The system does not replaceattentive driving. Failing to pay attention tothe road may result in a crash, serious injuryor death.
Do not use the adaptive cruise controlwhen entering or leaving a highway,on roads with intersections or roundaboutsor non-vehicular traffic or roads that arewinding, slippery, unpaved, or steep slopes.
Do not use the system in poor visibility,for example fog, heavy rain, spray orsnow.
WARNINGS
Do not use the system when towing atrailer with aftermarket trailer brakecontrols. Aftermarket trailer brakes will notfunction properly when you switch thesystem on because the brakes areelectronically controlled. Failing to do so mayresult in loss of vehicle control, which couldresult in serious injury.
Do not use tire sizes other than thoserecommended because this can affectthe normal operation of the system. Failureto do so may result in a loss of vehiclecontrol, which could result in serious injury.
Adaptive cruise control may not detectstationary or slow moving vehiclesbelow 6 mph (10 km/h).
Adaptive cruise control does not detectpedestrians or objects in the road.
Adaptive cruise control does not detectoncoming vehicles in the same lane.
Adaptive cruise control is not a crashwarning or avoidance system.
Note:It is your responsibility to stay alert,drive safely and be in control of the vehicleat all times.
The system adjusts your vehicle speed tomaintain the set gap between you and thevehicle in front of you in the same lane. Youcan select four gap settings.
The system uses a radar sensor that projectsa beam directly in front of your vehicle.
The adaptive cruise controls are on thesteering wheel.
Switching Adaptive Cruise Control On
Press ON.

GENERAL INFORMATION
Notice to utility vehicle and truckowners
WARNINGS
Utility vehicles have a significantlyhigher rollover rate than other types ofvehicles. To reduce the risk of serious injuryor death from a rollover or other crash youmust avoid sharp turns and abruptmaneuvers, drive at safe speeds for theconditions, keep tires properly inflated, neveroverload or improperly load your vehicle,and make sure every passenger is properlyrestrained.
In a rollover crash, an unbelted personis significantly more likely to die thana person wearing a seat belt. All occupantsmust wear seat belts, and children andinfants must use appropriate restraints tominimize the risk of injury or ejection.
Utility vehicles and trucks handle differentlythan passenger cars in the various drivingconditions that are encountered on streets,highways and off-road. Utility vehicles andtrucks are not designed for cornering atspeeds as high as passenger cars any morethan low-slung sports cars are designed toperform satisfactorily under off-roadconditions.
Study your owner's manual and anysupplements for specific information aboutequipment features, instructions for safedriving and additional precautions to reducethe risk of an accident or serious injury.
All-wheel drive system (if equipped)
WARNING
Do not become overconfident in theability of all-wheel-drive vehicles.Although an all-wheel-drive vehicle mayaccelerate better than a two-wheel drivevehicle in low traction situations, it will notstop any faster than two-wheel drivevehicles. Always drive at a safe speed.
A vehicle equipped with all-wheel drive hasthe ability to use all four wheels to poweritself. This increases traction which mayenable you to safely drive over terrain androad conditions that a conventionaltwo-wheel drive vehicle cannot.
For all-wheel-drive vehicles, a spare tire ofa different size other than the tire providedshould never be used. A dissimilar spare tiresize (other than the spare tire provided) ormajor dissimilar tire sized between the frontand rear axles could cause theall-wheel-drive system to stop functioningand default to front-wheel drive.

depends upon the actual conditions oftheir use, 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 assigned to thistire is based on straight-aheadbraking traction tests, and does notinclude acceleration, cornering,hydroplaning or peak tractioncharacteristics.
The traction grades, from highest tolowest are AA, A, B, and C. The gradesrepresent the tire’s ability to stop on wetpavement as measured under controlledconditions on specified government testsurfaces of asphalt and concrete. A tiremarked C may have poor tractionperformance.
Temperature A B C
WARNING
The temperature grade for this tireis established for a tire that isproperly inflated and not overloaded.Excessive speed, underinflation, orexcessive loading, either separately orin combination, can cause heat buildupand possible tire failure.
The temperature grades are A (thehighest), B and C, representing the tire’sresistance to the generation of heat andits ability to dissipate heat when testedunder controlled conditions on aspecified indoor laboratory test wheel.Sustained high temperature can causethe material of the tire to degenerate
and reduce tire life, and excessivetemperature can lead to sudden tirefailure. The grade C corresponds to alevel of performance which all
passenger car tires must meet under theFederal Motor Vehicle Safety StandardNo. 139. Grades B and A representhigher levels of performance on thelaboratory test wheel than the minimumrequired by law.

Location of the Tire Label
You will find a Tire Label containing tireinflation pressure by tire size and otherimportant information located on theB-Pillar or the edge of the driver’s door.
Inflating Your Tires
Safe operation of your vehicle requiresthat your tires are properly inflated.Remember that a tire can lose up to halfof its air pressure without appearing flat.
Every day before you drive, check yourtires. If one looks lower than the others,use a tire gauge to check pressure of alltires and adjust if required.
At least once a month and before longtrips, inspect each tire and check the tirepressure with a tire gauge (includingspare, if equipped). Inflate all tires to theinflation pressure recommended by FordMotor Company.
You are strongly urged to buy a reliabletire pressure gauge, as automaticservice station gauges may beinaccurate. Ford recommends the useof a digital or dial-type tire pressuregauge rather than a stick-type tirepressure gauge.
Use the recommended cold inflationpressure for optimum tire performanceand wear. Under-inflation orover-inflation may cause uneventreadwear patterns.
WARNING
Under-inflation is the most commoncause of tire failures and may resultin severe tire cracking, tread separationor blowout, with unexpected loss ofvehicle control and increased risk of
injury. Under-inflation increases sidewallflexing and rolling resistance, resultingin heat buildup and internal damage tothe tire. It also may result in unnecessarytire stress, irregular wear, loss of vehiclecontrol and accidents. A tire can lose upto half of its air pressure and not appearto be flat!

Note:If you overfill the tire, release airby pressing on the metal stem in thecenter of the valve. Then recheck thepressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,including the spare.
Note:Some spare tires operate at ahigher inflation pressure than the othertires. For T type mini-spare tires, see theDissimilar Spare Wheel and TireAssembly section. Store and maintainat 60 psi (4.15 bar). For full-size anddissimilar spare tires, see the DissimilarSpare Wheel and Tire AssemblyInformation section. Store and maintainat the higher of the front and rearinflation pressure as shown on the Tire
Label.
6. Visually inspect the tires to make surethere are no nails or other objectsembedded that could poke a hole in thetire and cause an air leak.
7. Check the sidewalls to make surethere are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel ValveStems
Periodically inspect the tire treads foruneven or excessive wear and removeobjects such as stones, nails or glassthat may be wedged in the treadgrooves. Check the tire and valve stemsfor holes, cracks, or cuts that may permitair leakage and repair or replace the tireand replace the valve stem. Inspect thetire sidewalls for cracking, cuts, bruisesand other signs of damage or excessivewear. If internal damage to the tire issuspected, have the tire demounted andinspected in case it needs to be repairedor replaced. For your safety, tires thatare damaged or show signs of excessivewear should not be used because theyare more likely to blow out or fail.
Improper or inadequate vehiclemaintenance can cause tires to wearabnormally. Inspect all your tires,including the spare, frequently, andreplace them if one or more of thefollowing conditions exist:
Tire Wear
When the tread is worn down to onesixteenth of an inch (2 millimeters), tiresmust be replaced to help prevent yourvehicle from skidding and hydroplaning.Built-in treadwear indicators, or wearbars, which look like narrow strips ofsmooth rubber across the tread willappear on the tire when the tread isworn down to one sixteenth of an inch(2 millimeters).
When the tire tread wears down to thesame height as these wear bars, the tire
is worn out and must be replaced.
