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 171).
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.

If Your Vehicle Goes Off the Edge of thePavement
•If your vehicle goes off the edge of thepavement, slow down, but avoid severebrake application, ease the vehicle backonto the pavement only after reducingyour speed. Do not turn the steeringwheel too sharply while returning to theroad surface.
•It may be safer to stay on the apron orshoulder of the road and slow downgradually before returning to thepavement. You may lose control if youdo not slow down or if you turn thesteering wheel too sharply or abruptly.
•It often may be less risky to strike smallobjects, such as highway reflectors, withminor damage to your vehicle rather thanattempt a sudden return to the pavementwhich could cause the vehicle to slidesideways out of control or rollover.Remember, your safety and the safety ofothers should be your primary concern.
If Your Vehicle Gets Stuck
WARNINGS
Always set the parking brake fully andmake sure you shift the gearshift leverto park (P). Switch the ignition off and removethe key whenever you leave your vehicle.
If the parking brake is fully released,but the brake warning lamp remainsilluminated, the brakes may not be workingproperly. Have your vehicle checked as soonas possible.
Do not spin the wheels at over 34 mph(55 km/h). The tires may fail and injurea passenger or bystander.
Note:Do not rock the vehicle if the engineis not at normal operating temperature ordamage to the transmission may occur.
Note:Do not rock the vehicle for more thana few minutes or damage to the transmissionand tires may occur or the engine mayoverheat.
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.
If your vehicle is equipped withAdvanceTrac® with Roll Stability Control™, itmay be beneficial to disengage theAdvanceTrac® with Roll Stability Control™system while attempting to rock the vehicle.
Emergency Maneuvers
•In an unavoidable emergency situationwhere a sudden sharp turn must bemade, remember to avoid "over-driving"your vehicle (that is, turn the steeringwheel only as rapidly and as far asrequired to avoid the emergency).Excessive steering will result in lessvehicle control, not more. Additionally,smooth variations of the acceleratorand/or brake pedal pressure should beutilized if changes in vehicle speed arecalled for. Avoid abrupt steering,

All-Wheel Drive (If Equipped)

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. Have thesystem checked by an authorized dealer. Ifyour vehicle has continuous vibration orshudder in the steering wheel while braking,have it checked by an authorized dealer.
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 333).
Note:Depending on applicable laws andregulations in the country for which yourvehicle was originally built, your brake lampsmay flash during heavy braking. Followingthis, your hazard lights may also flash whenyour vehicle comes to a stop.
See Warning Lamps andIndicators (page 106).
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. Movethe transmission to park (P), switch theengine off and apply the parking brake. Inspect the accelerator pedal for anyinterference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.
Brake Assist
Brake assist detects when you brake rapidlyby measuring the rate at which you press thebrake pedal. It provides maximum brakingefficiency as long as you press the pedal,and can 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 turn the ignition on. Ifthe light does not illuminate duringstart up, remains on or flashes, the systemmay be disabled. Have the system checkedby an authorized dealer. If the anti-lock brakesystem is disabled, normal braking is stilleffective.

PRINCIPLE OF OPERATION
The traction control system helps avoid drivewheel spin and loss of traction.
If your vehicle begins to slide, the systemapplies the brakes to individual wheels and,when needed, reduces engine power at thesame time. If the wheels spin whenaccelerating on slippery or loose surfaces,the system reduces engine power in orderto increase traction.
USING TRACTION CONTROL
WARNING
The stability and traction control lightilluminates steadily if the systemdetects a failure. Make sure you did notmanually disable the traction control systemusing the information display controls or theswitch. If the stability control and tractioncontrol light is still illuminating steadily, havethe system serviced by an authorized dealerimmediately. Operating your vehicle with thetraction control disabled could lead to anincreased risk of loss of vehicle control,vehicle rollover, personal injury and death.
The system automatically turns on each timeyou switch the ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Note:When you switch traction control off,stability control remains fully active.
Switching the System Off
When you switch the system off or on, amessage appears in the information displayshowing system status.
You can switch the system off by either usingthe information display controls or the switch.
