Note:Use of any fuel other than recommended fuel can cause
powertrain damage, impair the emission control system or cause loss of
vehicle performance. Any damage to the vehicle that is caused by the
use of fuel not recommended will not be covered under warranty.
Octane Recommendations
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87
is recommended. Some stations
offer fuels posted as Regular with
an octane rating below 87,
particularly in high altitude areas. Fuels with octane levels below 87 are
not recommended. Premium fuel will provide improved performance and
is recommended for severe duty usage such as trailer tow.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
• You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
• Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
• The service engine soon indicator may come on. For more information
on the service engine soon indicator, refer to the Instrument Cluster
chapter.
See Settings in theInstrument Cluster chapter for information on
calculating DTE (Distance to empty).

When fueling your vehicle:
1. Turn the engine off.
2. Open the fuel door by pulling the indent on the door.
3. Insert the fuel plug key (if equipped) into the locking plug and turn it
counterclockwise to unlock it.
4. Slowly insert the fuel filler nozzle fully into the fuel system, and leave
the nozzle fully inserted until you are done pumping.
5. After you are done pumping fuel, slowly remove the fuel filler
nozzle—allow about ten seconds after pumping fuel before removing the
fuel filler nozzle. This allows residual fuel to drain back into the fuel tank
and not spill onto the vehicle.
6. Reinstall the plug (if equipped) into the fuel fill inlet and turn the key
clockwise to lock.
Note:Do not overfill the tank or fuel spillage will occur.
If the fuel fill inlet was not properly closed, a Check Fuel Fill Inlet
message may appear on the information display. See the Information
Displays chapter for more information.
At the next opportunity, do the following:
1. Safely pull off the road.
2. Turn off the engine.
3. Open the fuel filler door and remove any visible debris from the fuel
fill opening.
4. Insert either the fuel fill nozzle or the fuel fill funnel provided with the
vehicle several times to dislodge any debris and/or allow the inlet to
close properly.
If this action corrects the problem, the message may not reset
immediately. It may take several driving cycles for the message to turn
off. A driving cycle consists of an engine start-up (after four or more
hours with the engine off) followed by city/highway driving. Continuing
to drive with the message on may cause the service engine soon lamp to
turn on as well.

EMISSION CONTROL SYSTEM
WARNING:Do not park, idle, or drive your vehicle in dry grass
or other dry ground cover. The emission system heats up the
engine compartment and exhaust system, which can start a fire.
WARNING: Exhaust leaks may result in entry of harmful and
potentially lethal fumes into the passenger compartment. If you
smell exhaust fumes inside your vehicle, have your dealer inspect your
vehicle immediately. Do not drive if you smell exhaust fumes.
Your vehicle is equipped with various emission control components and a
catalytic converter which will enable your vehicle to comply with
applicable exhaust emission standards. To make sure that the catalytic
converter and other emission control components continue to work
properly:
• Use only the specified fuel listed.
• Avoid running out of fuel.
• Do not turn off the ignition while your vehicle is moving, especially at
high speeds.
• Have the items listed in Scheduled Maintenance Information
performed according to the specified schedule.
The scheduled maintenance items listed in Scheduled Maintenance
Information are essential to the life and performance of your vehicle
and to its emissions system.
If other than Ford, Motorcraft® or Ford-authorized parts are used for
maintenance replacements or for service of components affecting
emission control, such non-Ford parts should be equivalent to genuine
Ford Motor Company parts in performance and durability.
Illumination of the service engine soon indicator, charging system
warning light or the temperature warning light, fluid leaks, strange odors,
smoke or loss of engine power could indicate that the emission control
system is not working properly.
An improperly operating or damaged exhaust system may allow exhaust
to enter the vehicle. Have a damaged or improperly operating exhaust
system inspected and repaired immediately.
Do not make any unauthorized changes to your vehicle or engine. By
law, vehicle owners and anyone who manufactures, repairs, services,

sells, leases, trades vehicles, or supervises a fleet of vehicles are not
permitted to intentionally remove an emission control device or prevent
it from working. Information about your vehicle’s emission system is on
the Vehicle Emission Control Information Decal located on or near the
engine. This decal also lists engine displacement.
Please consult your warranty information for complete emission warranty
information.
On-board Diagnostics (OBD-II)
Your vehicle is equipped with a computer that monitors the engine’s
emission control system. This system is commonly known as the
on-board diagnostics system (OBD-II). The OBD-II system protects the
environment by ensuring that your vehicle continues to meet
government emission standards. The OBD-II system also assists your
authorized dealer in properly servicing your vehicle.When the service engine soon indicator illuminates, the OBD-II
system has detected a malfunction. Temporary malfunctions
may cause the service engine soon indicator to illuminate.
Examples are:
1. The vehicle has run out of fuel—the engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel—the engine may misfire or run
poorly.
3. The fuel fill inlet may not have been properly closed. See Easy Fuel®
No Cap Fuel System in this chapter.
4. Driving through deep water—the electrical system may be wet.
These temporary malfunctions can be corrected by filling the fuel tank
with good quality fuel, properly closing the fuel fill inlet or letting the
electrical system dry out. After three driving cycles without these or any
other temporary malfunctions present, the service engine soon indicator
should stay off the next time the engine is started. A driving cycle
consists of a cold engine start-up followed by mixed city or highway
driving. No additional vehicle service is required.
If the service engine soon indicator remains on, have your vehicle
serviced at the first available opportunity. Although some malfunctions
detected by the OBD-II may not have symptoms that are apparent,
continued driving with the service engine soon indicator on can result in
increased emissions, lower fuel economy, reduced engine and
transmission smoothness, and can lead to more costly repairs.

Readiness for Inspection/Maintenance (I/M) Testing
Some state, provincial and local governments may have
Inspection/Maintenance (I/M) programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection could prevent
you from getting a vehicle registration.If the service engine soon indicator is on or the bulb does not
work, the vehicle may need to be serviced. See On-board
Diagnostics (OBD-II) in this chapter.
Your vehicle may not pass the I/M test if the service engine soon
indicator is on or not working properly (bulb is burned out), or if the
OBD-II system has determined that some of the emission control systems
have not been properly checked. In this case, the vehicle is considered
not ready for I/M testing.
If the vehicle’s engine or transmission has just been serviced, or the
battery has recently run down or been replaced, the OBD-II system may
indicate that the vehicle is not ready for I/M testing. To determine if the
vehicle is ready for I/M testing, turn the ignition key to the on position
for 15 seconds without cranking the engine. If the service engine soon
indicator blinks eight times, it means that the vehicle is not ready for I/M
testing; if the service engine soon indicator stays on solid, it means that
the vehicle is ready for I/M testing.
The OBD-II system is designed to check the emission control system
during normal driving. A complete check may take several days. If the
vehicle is not ready for I/M testing, the following driving cycle consisting
of mixed city and highway driving may be performed:
15 minutes of steady driving on an expressway or highway followed by
20 minutes of stop-and-go driving with at least four 30-second idle
periods.
Allow the vehicle to sit for at least eight hours without starting the
engine. Then, start the engine and complete the above driving cycle. The
engine must warm up to its normal operating temperature. Once the
engine is started, do not turn off the engine until the above driving cycle
is complete. If the vehicle is still not ready for I/M testing, the above
driving cycle will have to be repeated.
