Service Engine Soon
If the service engine soonindicator light stays illuminatedafter you start the engine, itindicates that the On Board Diagnosticssystem (OBD) has detected a malfunctionof the vehicle emissions control system.Refer to On Board Diagnostics (OBD) inthe Fuel and Refueling chapter for moreinformation about having your vehicleserviced. See Emission Control System(page 156).
If the light is blinking, engine misfire isoccurring which could damage yourcatalytic converter. Drive in a moderatefashion (avoid heavy acceleration anddeceleration) and have your vehicleserviced immediately.
WARNING
Under engine misfire conditions,excessive exhaust temperaturescould damage the catalyticconverter, the fuel system, interior floorcoverings or other vehicle components,possibly causing a fire. Have your vehiclechecked as soon as possible.
The service engine soon indicator lightilluminates when you first switch on theignition before engine start to check thebulb and to indicate whether the vehicleis ready for Inspection/Maintenance (I/M)testing.

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
