Octane Recommendations
•3.7L V6 engine
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. Do not use
fuels with octane
posted on pump below 87.
•5.0L V8 engine
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. Do not use fuels with
octane posted on pump below 87.
Premium fuel will provide improved performance and is recommended
for severe duty usage, such as trailer tow.
•For Shelby GT500 octane requirements, see the Shelby GT500
Supplement.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily 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, crank time will be a few seconds longer
than normal. With keyless ignition, just start the engine. Crank time
will be longer than usual.
•Normally, adding 1 gallon (3.8 liters) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8 liters) may be required.
•The service engine soon indicator may come on. For more information
on the service engine soon indicator, seeWarning Lamps and
Indicatorsin theInstrument Clusterchapter.
Fuel and Refueling161

For consistent results when filling the fuel tank:
•Turn the ignition off before fueling; an inaccurate reading results if the
engine is left running.
•Use the same fill rate (low–medium–high) each time the tank is filled.
•Allow no more than two automatic click–offs when filling.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles
(1600 kilometers) of driving (this is your engine’s break-in period); a
more accurate measurement is obtained after 2000 miles–3000 miles
(3200 kilometers–4800 kilometers). Also, fuel expense, frequency of
fill-ups or fuel gauge readings are not accurate ways to measure fuel
economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Calculate fuel economy as follows:
Standard: Divide miles traveled by gallons used.
Metric: Multiply liters used by 100, then divide by kilometers traveled.
Keep a record for at least one month and record the type of driving (city
or highway). This provides an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter show how temperature impacts fuel economy.
In general, lower temperatures mean lower fuel economy.

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 inScheduled Maintenance Information
performed according to the specified schedule.
The scheduled maintenance items listed inScheduled Maintenance
Informationare 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.

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. SeeOn-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.

AUTOMATIC TRANSMISSION (IF EQUIPPED)
WARNING:Always set the parking brake fully and make sure
the gearshift is latched in position P. Turn the ignition off and
remove the key whenever you leave your vehicle.
Your vehicle has been designed to improve fuel economy by reducing
fuel usage while coasting or decelerating. When you take your foot off
the accelerator pedal and the vehicle begins to slow down, the torque
converter clutch locks up and aggressively shuts off fuel flow to the
engine while decelerating. This fuel economy benefit may be perceived
as a light to medium braking sensation when removing your foot from
the accelerator pedal.
Position P
This position locks the transmission and prevents
the front wheels from turning.
To put your vehicle in gear:
•Press the brake pedal.
•Move the gearshift lever into the desired gear.
To put your vehicle in position P:
•Come to a complete stop.
•Move the gearshift lever and securely latch it in position P.
Position R
With the gearshift lever in position R, the vehicle will move backward.
Always come to a complete stop before shifting into and out of position R.
Position N
With the gearshift lever in position N, the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
Position D with overdrive
The normal driving position for the best fuel economy. The transmission
operates in gears one through six. The automatic transmission shift
strategy has the ability to detect hilly terrain or mountainous areas and
will provide a limited amount of grade assist features automatically.

selecting a gear that is out of the current vehicle speed range, the
vehicle will not make the requested shift and will blink the current gear.
Brake-shift interlock
WARNING:Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. Contact your authorized dealer as soon as possible to
have the system serviced immediately.
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved fromP(Park) when the ignition is
in the on position unless the brake pedal is pressed.
If you cannot move the gearshift lever out ofP(Park) with the ignition
on and the brake pedal pressed:
1. Apply the parking brake.
2. Using a flat head screwdriver or
similar tool, remove the chrome
bezel at the base of the gearshift
lever.
