Cleaner air

Ford approves the use of gasolines to improve air quality, including
reformulated gasolines that contain oxygenates up to 10% ethanol or
15% MTBE.

Running out of fuel

Avoid running out fuel because this situation may have an adverse affect
on modern powertrain components.

If you have run out of fuel:
• You may need to crank the engine several times before the system

starts to pump fuel from the tank to the engine.

• Your “Service Engine Soon” indicator may come on. For more

information on the “Service Engine Soon” indicator, refer to the
Instrumentation chapter.

Fuel Filter

Your vehicle is equipped with a fuel filter that is mounted on the
underbody.

For fuel filter replacement, see your dealer or a qualified service
technician. Refer to the Scheduled Maintenance Guide for the
appropriate intervals for changing the fuel filter.

If you replace the fuel filter, replace it with an authorized
Motorcraft part. The customer warranty may be void for any
damage to the fuel system if an authorized Motorcraft fuel filter
is not used.
