authorized dealer as soon as possible. Refer toWarning lights and
chimesin theInstrument Clusterchapter.

•4X4 LOW– displays when 4L is selected.
Positions of the Control Trac system
The Control Trac system functions
in four modes:
•2H (2WD)delivers power to the
rear wheels only. This is
appropriate for normal on-road
driving on dry pavement.
•4A (4X4 AUTO)provides
electronic control four-wheel
drive with power delivered to all
four wheels, as required, for
increased traction. The RTT location in the message center will
display “4X4 AUTO” when this position is selected. This is appropriate
for all on-road driving conditions, such as dry road surfaces, wet
pavement, snow or gravel.
•4H (4X4)provides electronically locked four-wheel drive power to
front and rear wheels. The RTT location in the message center will
display “4X4” when this position is selected. This position is not
recommended for use on dry pavement. This position is only intended
for severe winter or off-road conditions, such as deep snow, ice or
shallow sand.
•4L (4X4 LOW)provides electronically locked four-wheel drive when
extra power at reduced speeds is required. The RTT location in the
message center will display “4X4 LOW” when this position is selected.
This position is not recommended for use on dry pavement. Use this
position for off-road low-speed operation or when extra power is
required, such as climbing steep grades, going through deep sand or
pulling a boat out of the water.
Note:If your vehicle is equipped with AdvanceTracwith RSC, the
AdvanceTracwith RSC system will automatically turn off the stability
enhancement feature when you shift the Control Trac four-wheel drive
system into 4L (4X4 LOW). The brake traction enhancement feature will
still be enabled.

Cleaner air
Ford endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in theChoosing the Right
Fuelsection.
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
indicator may come on. For more information on the
“service engine soon” indicator
, refer toWarning lights and
chimesin theInstrument Clusterchapter.
ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fill-ups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1,000 miles
(1,600 km) of driving (engine break-in period). You will get a more
accurate measurement after 2,000 miles–3,000 miles
(3,000 km–5,000 km).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theMaintenance
product specifications and capacitiessection of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
