Introduction

FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
When Four±wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD power can be selected when
additional driving power is desired.
If equipped with the Electronic Shift 4WD System, and the
instrument panel control is moved to 4WD Low while the vehicle
is moving, the system will not engage and no damage will occur to
the 4WD system.
All utility-type vehicles and 4WD vehicles have special design and
equipment features to make them capable of performing in a wide
variety of off-road applications. Specific design characteristics give them
higher centers of gravity than ordinary passenger cars.
Utility and four-wheel drive vehicles arenotdesigned for
cornering at speeds as high as passenger cars any more than
low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns or abrupt maneuvers in these
vehicles.
4WD operation is not recommended on dry pavement. Doing so could
result in difficult disengagement of the transfer case, increased tire wear
and decreased fuel economy.
4WD system indicator lights
The 4WD system indicator lights illuminate only under the following
conditions. If these lights illuminate during normal driving, have your
vehicle serviced.
²4X4Ðilluminates when the
ignition is turned on or when 4H

²Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
²Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
Calculating 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 (in liters
or gallons).
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current kilometer (mileage) reading.
4. 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. Additionally, keeping records during summer and winter will
show how temperature impacts fuel economy. In general, lower
temperatures give lower fuel economy.
Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.

1Add 118 ml (4 oz.) of additive friction modifier C8AZ-19B546±A, Ford
specification EST-M2C118±A for complete refill of 8.8 inch and 9.75 inch
Traction-Lok axles. Add 236 ml (8 oz.) of additive friction modifier
C8AZ-19B546±A, Ford specification EST-M2C118±A for complete refill of
10.25 and 10.5 inch Traction-Lok axles.
2Refer to the dipstick for the type of transmission fluid required. Some
fluid labels may indicate dual usage such as MERCONtand MERCON
Vt. These dual usage fluids are not to be used in transmissions that use
only the MERCONttype fluid. These dual usage fluids may be used in
transmissions that require MERCONtV use.
Using a transmission fluid that indicates a dual usage (MERCONtand
MERCON Vt) in a transmission application requiring MERCONtmay
cause transmission damage. Use of any fluid other than the
recommended fluid may cause transmission damage.
