RUNNING OUT OF FUEL
Running out of fuel can cause damage notcovered by the vehicle Warranty.
If your vehicle runs out of fuel:
•Add a minimum of 1.3 gal (5 L) of fuelto restart the engine. If your vehicle isout of fuel and on a steep slope, morefuel may be required.
•You may need to switch the ignitionfrom off to on several times afterrefueling to allow the fuel system topump the fuel from the tank to theengine. When restarting, cranking timetakes a few seconds longer thannormal.
Filling a Portable Fuel Container
Use the following guidelines to avoidelectrostatic charge build-up, which canproduce a spark, when filling anungrounded fuel container:
•Only use an approved fuel container totransfer fuel to your vehicle. Place thecontainer on the ground when filling it.
•Do not fill a fuel container when it isinside your vehicle (including the cargoarea).
•Keep the fuel pump nozzle in contactwith the fuel container when filling it.
•Do not use a device that holds the fuelpump nozzle lever in the fill position.
Adding Fuel From a Portable FuelContainer
WARNINGS
Do not insert the nozzle of a fuelcontainer or an aftermarket funnelinto the fuel system filler neck. Thismay damage the fuel system filler neck orits seal and cause fuel to run onto theground.
WARNINGS
Do not try to pry open or push openthe capless fuel system with foreignobjects. This could damage the fuelsystem and its seal and cause injury to youor others.
Do not dispose of fuel in thehousehold refuse or the publicsewage system. Use an authorizedwaste disposal facility.
When refueling the vehicle fuel tank froma fuel container, use the fuel filler funnelincluded with your vehicle. See Fuel FillerFunnel Location (page 145).
Note:Do not use aftermarket funnels asthey will not work with the capless fuelsystem and can damage it.
When refueling the vehicle fuel tank froma fuel container, do the following:
1.Fully open the fuel tank filler door untilit engages.

5. Insert a fuel pump nozzle or the fuelfiller funnel provided with your vehiclein to the fuel tank filler pipe opening.This action should dislodge any debristhat may be preventing the fuel fillerinlet from fully closing.
Note: If this action corrects the problemthe message may not reset immediately. Ifthe message remains and the service enginesoon warning lamp appears in theinformation display, have your vehiclechecked as soon as possible.
FUEL CONSUMPTION
The advertised capacity is the indicatedcapacity and the empty reserve combined.In addition, the fuel tank contains an emptyreserve. Empty reserve is the amount offuel in the fuel tank after the fuel gaugeindicates empty.
Note:The amount of fuel in the emptyreserve varies and should not be relied uponto increase driving range.
•The usable capacity of the fuel tank isthe amount of fuel that you can add tothe fuel tank when the fuel gaugeindicates empty, before the first fuelfiller nozzle automatic shutoff event.
•The advertised capacity is equal to thevolumetric difference between actualfuel fill before the first fuel filler nozzleautomatic shutoff event and the fuelquantity when the fuel gauge indicatesempty. See Capacities andSpecifications (page 297). It is theusable capacity minus the emptyreserve.
•Due to the empty reserve, you may beable to add more fuel than theadvertised capacity of the fuel tankwhen the fuel gauge indicates empty.
Filling the Fuel Tank
For consistent results when refueling:
•Turn the ignition off before fueling; aninaccurate reading results if the engineis left running.
•Use the same fill rate(low-medium-high) each time the tankis filled.
•Allow no more than one automaticshut-off when refueling.
Results are most accurate when the fillingmethod is consistent.
Calculating Fuel Economy
Do not measure fuel economy during thefirst 1,000 mi (1,600 km) of driving (this isyour engine’s break-in period). A moreaccurate measurement is obtained after2,000 mi (3,200 km) to 3,000 mi(4,800 km). Also, fuel expense, frequencyof fill ups or fuel gauge readings are notaccurate ways to measure fuel economy.
1.Fill the fuel tank completely and recordthe initial odometer reading.
2. Each time you fill the fuel tank, recordthe amount of fuel added.
3. After at least three fill ups, fill the fueltank and record the current odometerreading.
4. Subtract your initial odometer readingfrom the current odometer reading.
To calculate L/100 km (liters per 100kilometers) fuel consumption, multiply theliters used by 100, then divide by kilometerstraveled. To calculate MPG (miles pergallon) fuel consumption, divide milestraveled by gallons used.

Keep a record for at least one month andrecord the type of driving (city or highway).This provides an accurate estimate of yourvehicle's fuel economy under currentdriving conditions. Keeping records duringsummer and winter will show howtemperature impacts fuel economy.
Conditions
•Heavily loading your vehicle reducesfuel economy.
•Carrying unnecessary weight in yourvehicle may reduce fuel economy.
•Adding certain accessories to yourvehicle such as bug deflectors, rollbarsor light bars, running boards and skiracks may reduce fuel economy.
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures.
•Fuel economy may decrease whendriving short distances.
•You will get better fuel economy whendriving on flat terrain than when drivingon hilly terrain.
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 the catalytic converterand other emission control componentscontinue to work properly:
•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 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 remove

an 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 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 147).
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 malfunctions
present, 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 on

position 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.
