Filling the Fuel Tank
For consistent results when refueling:
•Switch the ignition off before fueling,an inaccurate reading results if youleave the engine running.
•Use the same fill rate,low-medium-high, each time you fillthe tank.
•Allow no more than one automaticshut-off when refueling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Your vehicle calculates fuel economyfigures through the trip computer averagefuel function. See Information Displays(page 98).
The first 1,000 mi (1,600 km) of driving isthe break-in period of the engine. Thesystem obtains a more accuratemeasurement after 2,000–3,000 mi(3,200–4,800 km).
Keep a record for at least one month andrecord the type of driving, for example cityor highway. This provides an accurateestimate of your vehicle’s fuel economyunder current driving conditions. Keepingrecords during summer and winter showshow temperature impacts fuel economy.

CATALYTIC CONVERTER
WARNING: Do not park, idle ordrive your vehicle on dry grass or otherdry ground cover. The emission systemheats up the engine compartment andexhaust system, creating the risk of fire.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the catalytic converter.The catalytic converter heats up to a veryhigh temperature after only a shortperiod of engine operation and stays hotafter the engine is switched off.
WARNING: Exhaust leaks mayresult in entry of harmful and potentiallylethal fumes into the passengercompartment. If you smell exhaustfumes inside your vehicle, have yourvehicle inspected immediately. Do notdrive if you smell exhaust fumes.
Your vehicle has various emission controlcomponents and a catalytic converter thatenables it to comply with applicableexhaust emission standards.
To make sure that the catalytic converterand other emission control componentscontinue to work properly:
•Do not crank the engine for more than10 seconds at a time.
•Do not run the engine with a spark pluglead disconnected.
•Do not push-start or tow-start yourvehicle. Use booster cables. See JumpStarting the Vehicle (page 235).
•Use only the specified fuel listed.
•Do not switch the ignition off when yourvehicle is moving.
•Avoid running out of fuel.
•Have the items listed in scheduledmaintenance information performedaccording to the specified schedule.
Note:Resulting component damage maynot be covered by the vehicle Warranty.
The scheduled maintenance items listedin scheduled maintenance information areessential to the life and performance ofyour vehicle and to its emissions system.
If you use anything other than Ford,Motorcraft or Ford-authorized parts formaintenance replacements or for serviceof components affecting emission control,such non-Ford parts should be equivalentto genuine 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 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.

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 theenvironment by making sure that yourvehicle continues to meet governmentemission standards. The OBD-II systemalso assists a service technician in properlyservicing your vehicle.
When the service engine soonindicator illuminates, the OBD-IIsystem has detected amalfunction. Temporary malfunctions maycause the service engine soon indicator toilluminate. Examples are:
1.Your vehicle has run out of fuel—theengine may misfire or run poorly.
2.Poor fuel quality or water in thefuel—the engine may misfire or runpoorly.
3.The fuel fill inlet may not have closedproperly. See Refueling (page 155).
4.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 mixed city andhighway 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 for Inspection andMaintenance (I/M) Testing
Some state and 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, your vehicle may needservice. See On-Board Diagnostics.
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, the 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 crankingthe engine. If the service engine soonindicator blinks eight times, it means thatthe vehicle is not ready for I/M testing; ifthe service engine soon indicator stays onsolid, it means that your vehicle is readyfor 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,you can perform the following driving cycleconsisting of mixed city and highwaydriving:
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 leasteight hours with the ignition off. Then,start the vehicle and complete theabove driving cycle. The vehicle mustwarm up to its normal operatingtemperature. Once started, do not turnoff the vehicle until the above drivingcycle is complete.
If the vehicle is still not ready for I/Mtesting, you need to repeat the abovedriving cycle.
