•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars/light bars, running boards, skiracks) may reduce fuel economy.
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.
•Transmissions give their best fueleconomy when operated in the topcruise gear and with steady pressureon the gas pedal.
•Close windows for high speed driving.
EMISSION CONTROL SYSTEM
WARNINGS
Do not park, idle, or drive your vehiclein dry grass or other dry ground cover.The emission system heats up theengine compartment and exhaust system,which can start a fire.
Exhaust leaks may result in entry ofharmful and potentially lethal fumesinto the passenger compartment. Ifyou smell exhaust fumes inside yourvehicle, have your dealer inspect yourvehicle immediately. Do not drive if yousmell exhaust fumes.
Your vehicle is equipped with variousemission control components and acatalytic converter that will enable yourvehicle to comply with applicable exhaustemission standards. To make sure that thecatalytic converter and other emissioncontrol components continue to workproperly:
•Use only the specified fuel listed.
•Avoid running out of fuel.
•Do not turn off the ignition while yourvehicle is moving, especially at highspeeds.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use parts other than Ford, Motorcraftor Ford-authorized parts for maintenancereplacements, or for service ofcomponents affecting emission control,such non-Ford parts should be theequivalent to genuine Ford Motor Companyparts in performance 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 damagedexhaust system may allow exhaust toenter the vehicle. Have a damaged orimproperly operating exhaust systeminspected and repaired 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 vehiclesare not permitted to intentionally removean emission control device or prevent itfrom working. Information about yourvehicle’s emission system is on the VehicleEmission Control Information Decallocated on or near the engine. This decalalso lists engine displacement
Please consult your warranty informationfor complete details.

On-Board Diagnostics (OBD-II)
Your vehicle is equipped with an on-boarddiagnostics system (OBD-II) that monitorsthe engine’s emission control system. Thissystem protects the environment byensuring that your vehicle continues tomeet government emission standards. TheOBD-II system also assists your authorizeddealer in properly servicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate.
Examples of temporary malfunctions are:
•the vehicle has run out of fuel—theengine may misfire or run poorly
•poor fuel quality or water in thefuel—the engine may misfire or runpoorly
•the fuel fill inlet may not have beenproperly closed See Refueling (page138).
•driving through deep water—theelectrical system may be wet.
You can correct these temporarymalfunctions by filling the fuel tank withgood quality fuel, properly closing the fuelfill inlet or letting the electrical system dryout. After three driving cycles without theseor any other temporary malfunctionspresent, the service engine soon indicatorshould stay off the next time you start theengine. A driving cycle consists of a coldengine startup followed by mixedcity/highway driving. No additional vehicleservice is required.
If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II maynot have symptoms that are apparent,continued driving with the service enginesoon indicator on can result in increasedemissions, lower fuel economy, reducedengine and transmission smoothness, andlead to more costly repairs.
Readiness forInspection/Maintenance (I/M)Testing
Some state/provincial and localgovernments may haveInspection/Maintenance (I/M) programsto inspect the emission control equipmenton your vehicle. Failure to pass thisinspection could prevent you from gettinga vehicle registration.
If the service engine soonindicator is on or the bulb doesnot work, you may need to havethe vehicle serviced. See On-BoardDiagnostics (OBD-II).
Your vehicle may not pass the I/M test ifthe service engine soon indicator is on ornot working properly (bulb is burned out),or if the OBD-II system has determinedthat some of the emission control systemshave not been properly checked. In thiscase, your vehicle is not ready for I/Mtesting.
If the vehicle’s engine or transmission hasjust been serviced, or the battery hasrecently run down or been replaced, theOBD-II system may indicate that thevehicle is not ready for I/M testing. Todetermine if the vehicle is ready for I/Mtesting, turn the ignition key to the onposition for 15 seconds without cranking

How Your Vehicle Differs FromOther Vehicles
WARNING
Vehicles with a higher center ofgravity such as utility and four-wheeldrive vehicles handle differently thanvehicles with a lower center of gravity.Utility and four-wheel drive vehicles arenot designed for cornering at speeds ashigh as passenger cars any more thanlow-slung sports cars are designed toperform satisfactorily under off-roadconditions. Avoid sharp turns, excessivespeed and abrupt maneuvers in thesevehicles. Failure to drive cautiously couldresult in an increased risk of loss of vehiclecontrol, vehicle rollover, personal injury anddeath.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle may behigher to allow it to travel over roughterrain without getting hung up ordamaging underbody components.
The differences that make your vehicle soversatile also make it handle differentlythan an ordinary passenger car.
Maintain steering wheel control at alltimes, especially in rough terrain. Sincesudden changes in terrain can result inabrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes.
Drive cautiously to avoid vehicle damagefrom concealed objects such as rocks andstumps.
You should either know the terrain orexamine maps of the area before driving.Map out your route before driving in thearea. To maintain steering and brakingcontrol of your vehicle, you must have allfour wheels on the ground and they mustbe rolling, not sliding or spinning.
Driving Off-Road With Truck andUtility Vehicles
Note:On some models, the initial shift fromtwo-wheel drive to four-wheel drive whilethe vehicle is moving can cause somemomentary clunk and ratcheting sounds.This is the front drivetrain coming up tospeed and the automatic locking hubsengaging and is not cause for concern.
Note:Your vehicle may be equipped witha front air dam that can become damaged(due to reduced ground clearance) whentaking your vehicle off-road. This air damcan be taken off by removing two bolts.
Four-wheel drive vehicles are speciallyequipped for driving on sand, snow, mudand rough terrain and have operatingcharacteristics that are somewhatdifferent from conventional vehicles, bothon and off the road.
Power is supplied to all four wheelsthrough a transfer case. On Four-wheeldrive vehicles, the transfer case allows youto select 4WD when necessary.Information on transfer case operation andshifting procedures can be found in thischapter. Information on transfer casemaintenance can be found in theMaintenance chapter. You should becomethoroughly familiar with this informationbefore you operate your vehicle.
