Using fuel blended with alcohol may lower fuel economy.
•
Fuel economy may decrease with lower temperatures during the first
8–10 miles (12–16 km) of driving.
•
Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•
Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•
Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.

Close windows for high speed driving.
EPA fuel economy estimates
If applicable, every new vehicle should have a sticker on the window
called the Monroney Label which contains EPA fuel economy estimates.
Contact your authorized dealer if the Monroney Label is not supplied
with your vehicle. The EPA fuel economy estimates should be your guide
for the fuel economy comparisons with other vehicles. Your fuel economy
may vary depending upon the method of operation and conditions.
EMISSION CONTROL SYSTEM
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
威
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.
