FUEL INFORMATION
Important safety precautions
Do not overfill the fuel tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray and fire.
The fuel system may be under pressure. If the fuel cap is venting
vapor or if you hear a hissing sound, wait until it stops before
completely removing the cap.
Automotive fuels can cause serious injury or death if misused or
mishandled.

The amount of Empty Reserve varies and should not be relied
upon to increase driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel
the full amount of the advertised capacity of the fuel tank due to
the empty reserve still present in the tank.
Filling the tank
For consistent results:
•Use the same fill rate setting (low—medium—high) each time
during filling.
•Allow three automatic click-offs when filling.
•Always use fuel of a known quality, preferably a national brand.
•Have the vehicle loading and distribution the same every time.
•When refueling a vehicle equipped with dual fuel tanks, if the two
tanks are not filled equally, the fuel gauge reading may fluctuate
slightly until the fuel level between the two tanks balance out and
become equal.
Your results will be most accurate if your filling method is consistent.
Calculating fuel economy
1. Fill the fuel tank(s) completely and record the initial odometer
reading (in kilometers or miles).
2. Each time you fill the tank(s), record the amount of fuel added (in
liters or gallons).
3. After at least three to five tank fill-ups, fill the fuel tank(s) and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5.
Follow one of the simple calculations in order to determine fuel economy:
Multiply liters used by 100, then divide by total kilometers
traveled.
Divide total miles traveled by total gallons used.
Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle’s fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.

* Coolant protection checks should be made just prior to the onset of
freezing weather, where applicable. If coolant is dirty or rusty in
appearance, the system should be drained, flushed and refilled with the
prescribed solution of cooling system fluid and water. Use only
permanent type coolant that meets Ford specifications ESE-M97B18-C.
See the engine manufacturer’s operating guide for supplimental
corrosion inhibitor specifications.
In addition to the items to be performed daily or at each oil change, the
following need to be completed as specified:
5 000 MILES
•Initial change—change the lubricant in the manual shift transmission
–5 speed and 6 speed Eaton manual transmission. (Not required
when equipped with optional synthetic lubricant.)
20 000 MILES
•Replace the fuel filter.*
30 000 MILES
•Replace the engine spin-on coolant filter.*
•Repack and adjust the front wheel bearings—grease-filled hubs.
40 000 MILES
•Replace the fuel filter.*
