FUEL CONSUMPTION
Advertised Capacity
The advertised capacity is the maximumamount of fuel that you can add to the fueltank after running out of fuel. Included in theadvertised capacity is an empty reserve. Theempty reserve is an unspecified amount offuel that remains in the fuel tank when thefuel gauge indicates empty.
Note:The amount of fuel in the emptyreserve varies and should not be relied uponto increase driving range.
Fuel Economy
Your vehicle calculates fuel economy figuresthrough the trip computer average fuelfunction.
The first 1,000 mi (1,500 km) of driving is thebreak-in period of the engine. A moreaccurate measurement is obtained after2,000 mi (3,000 km).
Impacting Fuel Economy
•Incorrect tire inflation pressures.
•Fully loading your vehicle.
•Carrying unnecessary weight.
•Adding certain accessories to yourvehicle such as bug deflectors, rollbarsor light bars, running boards and skiracks.
•Using fuel blended with alcohol. SeeFuel Quality (page 200).
•Fuel economy may decrease with lowertemperatures.
•Fuel economy may decrease whendriving short distances.
•You may get better fuel economy whendriving on flat terrain than when drivingon hilly terrain.

EMISSION LAW
WARNING: Do not remove or alterthe original equipment floor covering orinsulation between it and the metal floorof the vehicle. The floor covering andinsulation protect occupants of the vehiclefrom the engine and exhaust system heatand noise. On vehicles with no originalequipment floor covering insulation, do notcarry passengers in a manner that permitsprolonged skin contact with the metal floor.Failure to follow these instructions mayresult in fire or personal injury.
U.S. federal laws and certain state lawsprohibit removing or rendering inoperativeemission control system components. Similarfederal or provincial laws may apply inCanada. We do not approve of any vehiclemodification without first determiningapplicable laws.
Tampering with emissions controlsystems including related sensorsor the Diesel Exhaust Fluid systemcan result in reduced engine power and theillumination of the service engine soon light.
Tampering With a Noise ControlSystem
Federal laws prohibit the following acts:
•Removal or rendering inoperative by anyperson other than for purposes ofmaintenance.
•Repair or replacement of any device orelement of the design incorporated intoa new vehicle for the purpose of noisecontrol prior to its sale or delivery to theultimate purchaser or while it is in use.
•The use of the vehicle after any personremoves or renders inoperative anydevice or element of the design.
The U.S. Environmental Protection Agencymay presume to constitute tampering asfollows:
•Removal of hood blanket, fender apronabsorbers, fender apron barriers,underbody noise shields or acousticallyabsorptive material.
•Tampering or rendering inoperative theengine speed governor, to allow enginespeed to exceed manufacturerspecifications.
If the engine does not start, runs rough,experiences a decrease in engineperformance, experiences excess fuelconsumption or produces excessive exhaustsmoke, check for the following:
•A plugged or disconnected air inletsystem hose.
•A plugged engine air filter element.

Engine Emission Control

The scheduled maintenance items listed inscheduled maintenance information areessential to the life and performance of yourvehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for service ofcomponents affecting emission control, suchnon-Ford parts should be equivalent togenuine Ford Motor Company parts inperformance and durability.
Illumination of the service engine soonindicator, charging system warning light orthe temperature warning light, fluid leaks,strange odors, smoke or loss of enginepower could indicate that the emissioncontrol system is not working properly.
An improperly operating or damaged exhaustsystem may allow exhaust to enter thevehicle. Have a damaged or improperlyoperating exhaust system inspected andrepaired immediately.
Do not make any unauthorized changes toyour vehicle or engine. By law, vehicleowners and anyone who manufactures,repairs, services, sells, leases, tradesvehicles, or supervises a fleet of vehicles arenot permitted to intentionally remove anemission control device or prevent it fromworking. Information about your vehicle’semission system is on the Vehicle EmissionControl Information Decal located on or nearthe engine. This decal also lists enginedisplacement.
Please consult your warranty information forcomplete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as theon-board diagnostics system (OBD-II) thatmonitors the engine’s emission controlsystem. The system protects the environmentby making sure that your vehicle continuesto meet government emission standards. TheOBD-II system also assists a servicetechnician in properly servicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected a malfunction.Temporary malfunctions may cause theservice engine soon indicator to illuminate.Examples are:
1. Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in the fuel—theengine may misfire or run poorly.
3. The fuel fill inlet may not have closedproperly. See Refueling (page 202).
4. Driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank with goodquality fuel, properly closing the fuel fill inletor letting the electrical system dry out. Afterthree driving cycles without these or anyother temporary malfunctions present, theservice engine soon indicator should stay offthe next time you start the engine. A drivingcycle consists of a cold engine startupfollowed by mixed city and highway driving.No additional vehicle service is required.

Basic Operating Principles
•Do not use SLIPPERY, DEEPCONDITIONS or SLOW CLIMB on dry,hard surfaced roads. Doing so producesexcessive noise, increases tire wear andmay damage drive components. The 4X4system in these modes is only intendedfor consistently slippery or loosesurfaces.
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•When driving your vehicle on surfacesmade slippery by loose sand, water,gravel, snow or ice, proceed with care.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce yourvehicle speed and avoid severe braking.When your vehicle speed has been reducedease your vehicle back onto the road. Donot turn the steering wheel sharply whenreturning your vehicle to the road.
It may be safer to stay on the shoulder of theroad and slow down gradually beforereturning to the road. You may lose controlif you do not slow down or if you turn thesteering wheel too sharply or abruptly.
It may be less risky to strike small objects,such as freeway reflectors, with minordamage to your vehicle rather than attempta sudden return to the road which couldcause your vehicle to slide sideways out ofcontrol or roll over. Remember, your safetyand the safety of others should be yourprimary concern.
If your vehicle gets stuck
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
Note:Do not rock your vehicle if the engineis not at normal operating temperature,damage to the transmission may occur.
Note:Do not rock your vehicle for more thana minute, damage to the transmission andtires may occur or the engine may overheat.
If your vehicle gets stuck in mud or snow itmay be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts, in a steady pattern. Presslightly on the accelerator in each gear.
Emergency Maneuvers
In an unavoidable emergency situationwhere a sudden sharp turn must be made,remember to avoid over-driving your vehicle(i.e. turn the steering wheel only as rapidlyand as far as required to avoid theemergency). Excessive steering can resultin loss of vehicle control. Apply smoothpressure to the accelerator pedal or brakepedal when changes in vehicle speed arerequired. Avoid abrupt steering, accelerationand braking. This could result in an increasedrisk of vehicle roll over, loss of vehicle controland personal injury. Use all available roadsurface to bring your vehicle to a safedirection of travel.
In the event of an emergency stop, avoidskidding the tires and do not attempt anysharp steering wheel movements.

GENERAL INFORMATION
Note: Occasional brake noise is normal. Ifa metal-to-metal, continuous grinding orcontinuous squeal sound is present, thebrake linings may be worn-out and anauthorized dealer should check them. If thevehicle has continuous vibration or shudderin the steering wheel while braking, anauthorized dealer should check your vehicle.
Note:Brake dust may accumulate on thewheels, even under normal drivingconditions. Some dust is inevitable as thebrakes wear and does not contribute tobrake noise. See Cleaning the Wheels(page 389).
See Warning Lamps andIndicators (page 113).
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when driving from a car wash orstanding water to dry the brakes.
Brake Over Accelerator
In the event the accelerator pedal becomesstuck or entrapped, apply steady and firmpressure to the brake pedal to slow thevehicle and reduce engine power. If youexperience this condition, apply the brakesand bring your vehicle to a safe stop. Switchthe engine off, move the transmission to park(P) and apply the parking brake. Inspect theaccelerator pedal and the area around it forany items or debris that may be obstructingits movement.If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Emergency Brake Assist
Emergency brake assist detects when youbrake heavily by measuring the rate at whichyou press the brake pedal. It providesmaximum braking efficiency as long as youpress the pedal. Emergency brake assistcan reduce stopping distances in criticalsituations.
Anti-lock Brake System
This system helps you maintain steeringcontrol during emergency stops by keepingthe brakes from locking.
This lamp momentarily illuminateswhen you switch the ignition on. Ifthe light does not illuminate duringstart up, remains on or flashes, the anti-lockbraking system may be disabled. Have thesystem checked by an authorized dealer. Ifthe anti-lock brake system is disabled,normal braking is still effective.
If the brake warning lampilluminates with the parking brakereleased, have your brake systemserviced immediately.
It also illuminates momentarily when youswitch the ignition on to confirm the lamp isfunctional. If it does not illuminate when youswitch the ignition on, or begins to flash atany time, have the system checked by anauthorized dealer.
