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 Lincoln,Motorcraft or Lincoln-authorized parts formaintenance replacements or for service ofcomponents affecting emission control, suchnon-Lincoln parts should be equivalent togenuine Lincoln 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 169).
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.

Engine Emission Control

If the service engine soon indicator remainson, have your vehicle serviced at the firstavailable opportunity. Although somemalfunctions detected by the OBD-II may nothave symptoms that are apparent, continueddriving with the service engine soon indicatoron can result in increased emissions, lowerfuel economy, reduced engine andtransmission smoothness and lead to morecostly repairs.
Readiness for Inspection andMaintenance (I/M) Testing
Some state and provincial and localgovernments may haveInspection/Maintenance (I/M) programs toinspect the emission control equipment onyour vehicle. Failure to pass this inspectioncould prevent you from getting a vehicleregistration.
If the service engine soon indicatoris on or the bulb does not work,your vehicle may need service.See On-Board Diagnostics.
Your vehicle may not pass the I/M test if theservice engine soon indicator is on or notworking properly (bulb is burned out), or ifthe OBD-II system has determined that someof the emission control systems have notbeen properly checked. In this case, thevehicle is not ready for I/M testing.
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 the vehicleis not ready for I/M testing. To determine ifthe vehicle is ready for I/M testing, turn theignition key to the on position for 15 secondswithout cranking the engine. If the serviceengine soon indicator blinks eight times, itmeans that the vehicle is not ready for I/Mtesting; if the service engine soon indicatorstays on solid, it means that your vehicle isready for I/M testing.
The OBD-II system checks the emissioncontrol system during normal driving. Acomplete check may take several days.
If the vehicle is not ready for I/M testing, youcan perform the following driving cycleconsisting of mixed city and highway driving:
1. 15 minutes of steady driving on anexpressway or highway followed by 20minutes of stop-and-go driving with atleast four 30-second idle periods.
2.Allow your vehicle to sit for at least eighthours with the ignition off. Then, start thevehicle and complete the above drivingcycle. The vehicle must warm up to itsnormal operating temperature. Oncestarted, do not turn off the vehicle untilthe above driving cycle is complete.
If the vehicle is still not ready for I/M testing,you need to repeat the above driving cycle.

USING ALL-WHEEL DRIVE
All-Wheel Drive (AWD) uses all four wheelsto power the vehicle. This increases traction,enabling you to drive over terrain and roadconditions that a conventional two-wheeldrive vehicle cannot. The AWD system isactive all the time and requires no input fromthe operator.
Note:Your vehicle may be equipped withDynamic Torque Vectoring. This feature usesall four wheels to power the vehicle andindependently controls the torque to eachrear wheel. In addition, the system has theability to over speed the outside rear wheelin a turn. This increases traction andhandling performance, allowing the vehicleto travel through road conditions and havepath following capability superior toconventional two-wheel drive and AWDvehicles. The Dynamic Torque Vectoringsystem is active all the time and requires noinput 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:When an AWD system fault is present,the warning AWD Malfunction ServiceRequired displays in the information display.The AWD system is not functioning correctlyand defaulted to front-wheel drive. Whenthis warning displays, have your vehicleserviced at an authorized dealer.
Note: The AWD OFF message may alsoappear in the information display if the AWDsystem overheats and defaults to front-wheeldrive. This may occur if the vehicle isoperated in extreme conditions withexcessive wheel slip, such as deep sand. To resume normal AWD function as soon aspossible, stop the vehicle in a safe locationand stop the engine for at least 10 minutes. After the engine has been restarted and theAWD system has adequately cooled, theAWD OFF message will turn off and normalAWD function returns. If the engine is notstopped, the AWD OFF message turns offwhen the system cools and normal AWDfunction returns.

Operating AWD Vehicles With Spareor Mismatched Tires
WARNING: Only use replacement tiresand wheels that are the same size, loadindex, speed rating and type (such asP-metric versus LT-metric or all-seasonversus all-terrain) as those originally providedby Ford. The recommended tire and wheelsize may be found on either the SafetyCompliance Certification Label (affixed toeither the door hinge pillar, door-latch post,or the door edge that meets the door-latchpost, next to the driver’s seating position), orthe Tire Label which is located on the B-Pillaror edge of the driver’s door. If thisinformation is not found on these labels, thenyou should contact your authorized dealeras soon as possible. Use of any tire or wheelnot recommended by Ford can affect thesafety and performance of your vehicle,which could result in an increased risk of lossof vehicle control, vehicle rollover, personalinjury and death.
A spare tire of a different size other than thetire provided should never be used. TheAWD system may disable automatically andenter front-wheel drive only mode to protectdriveline components if a non-full sized tireis installed. This condition may display anAWD OFF message in the informationdisplay. If there is an AWD OFF message inthe information display from using a non-fullsized spare tire, this indicator should turn offafter reinstalling the repaired or replacednormal road tire and cycling the ignition offand on. It is recommended to reinstall therepaired or replaced road tire as soon aspossible.
Major dissimilar tire sizes between the frontand rear axles (for example, 17 inch lowprofile tires on the front axle and 22 inch highprofile tires on the rear axle) could cause theAWD system to stop functioning and defaultto front-wheel drive or damage the AWDsystem. However, the AWD system iscapable of tolerating any combination of newand worn tires of the same original tire size.For example, using 3 worn tread tires and 1new tread tire all of the same original tiresize, can be tolerated by the AWD system.
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.
When driving at slow speeds in deep sandunder high outside temperatures, use a lowgear when possible. Lower gear operationwill maximize the engine and transmissioncooling capability.
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.
