AVG SPEED (average speed)
Select this function to display your
average speed in miles per hour or
kilometers per hour.
Your vehicle must be moving to
calculate your average speed. When your vehicle is not moving, the
average speed is displayed at 0 kilometers (0 miles) per hour.
Message center indicator lights
Check air suspension
Briefly illuminates when the ignition
is turned ON. This light will remain
on to indicate that the air
suspension switch is off or to
indicate a possible system fault. For
more information on the air
suspension system, refer to the
Drivingchapter.
Overdrive off
Illuminates when the transmission
control switch (TCS) has been
pushed. When the light is on, the
transmission does not shift into
overdrive. If the light does not come
on when the TCS is depressed or if
the light flashes when you are
driving, have your vehicle serviced.
Door ajar
Illuminates when one of the doors is
not completely shut and the ignition
is turned to ON. With the ignition
ON, this light will flash five times
and sound a tone for one second,
then remain on (if a door is open).

gears one through three. Drive provides more engine braking than
Overdrive and is useful when:
²driving with a heavy load
²towing a trailer up or down steep hills
²additional engine braking is desired. If towing a trailer, refer to
Driving while you towin theTowing a trailerchapter.
To return to Overdrive mode, press the transmission control switch. The
O/D OFF indicator light will no longer be illuminated.
Each time the vehicle is started, the transmission will automatically
return to normal Overdrive mode.
Every time the vehicle is shut off and restarted, you must press the
transmission control switch to cancel overdrive operation if the Overdrive
mode is not desired.
2 (Second)
Use 2 (Second) to start-up on
slippery roads or to provide
additional engine braking on
downgrades.
1 (First)
Use 1 (Low) to provide maximum
engine braking on steep
downgrades. Upshifts can be made
by shifting to 2 (Second) or to
Overdrive. Selecting 1 (Low) at
higher speeds causes the transmission to shift to a lower gear, and will
shift to 1 (Low) after vehicle decelerates to the proper speed.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
²Base Curb Weight: Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include passengers or
aftermarket equipment.
²Payload: Combined maximum allowable weight of cargo, passengers
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle's main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
Always replace the cover to the Power Distribution Box before
reconnecting the battery or refilling fluid reservoirs.

TRANSMISSION FLUID
Checking and adding automatic transmission fluid
Follow the scheduled service intervals outlined in the ªService Guide.º
Before adding any fluid, make sure the correct type is used. The type of
fluid used is normally indicated on the dipstick and/or dipstick handle
and also in theLubricant specificationssection in theCapacities and
specificationschapter.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
Do not drive the vehicle if the fluid
level is below the bottom hole on
the dipstick and outside
temperatures are above 10ÉC (50ÉF)
(see figure to the right).
Your transmission does not use up fluid. However, it is recommended
that you check the transmission fluid at least twice a year. The fluid level
should be checked if the transmission is not working properly, i.e., if the
transmission slips or shifts slowly or if you notice some sign of fluid
leakage.
Transmission fluid should be checked at normal operating temperatures
66ÉC-77ÉC (150ÉF-170ÉF) on a level surface. The normal operating
temperature can be reached after approximately 32 km (20 miles) of
driving.
The transmission fluid should be in
this range if at normal operating
temperature (66ÉC-77ÉC
[150ÉF-170ÉF]) (see figure to the
right).
The transmission fluid should be in
this range if at room temperature
(10ÉC-35ÉC [50ÉF-95ÉF]) (see figure
to the right).
If your vehicle has been operated for an extended period at high speeds,
in city traffic during hot weather or pulling a trailer, the vehicle should
be turned off for about 30 minutes to allow the fluid to cool before
checking.
1. Park the vehicle on a level surface and engage the parking brake.

2. With the parking brake engaged
and your foot on the brake pedal,
start the engine and move the
gearshift lever through all of the
gear ranges. Allow sufficient time for each gear to engage.
3. Latch the gearshift lever in P (Park) and leave the engine running.
4. Remove the dipstick, wiping it clean with a clean, dry lint free rag.
5. Install the dipstick making sure it is fully seated in the filler tube.
6. Remove the dipstick and inspect the fluid level. The fluid level should
be within the top hole area on the dipstick.
7. If necessary, add fluid in 250ml (1/2 pint) increments through the filler
tube until the level is correct.
8. If an overfill occurs, excess fluid should be removed by a qualified
technician.
An overfill condition of transmission fluid may cause shift and/or
engagement concerns and/or possible damage.
If the fluid level is above the
crosshatch (hot operating range)
area after driving the vehicle for
approximately 30 km (20 miles),
excess transmission fluid should be
removed by a qualified technician.
BATTERY
Your vehicle is equipped with a
Motorcraft maintenance-free battery
which normally does not require
additional water during its life of
service.P R N D 2 1

specification EST-M2C118±A for complete refill of Traction-Lok axles.
Service refill capacities are determined by filling the rear axle 6 mm to
14 mm (1/4 inch to 9/16 inch) below the bottom of the filler hole.
Rear axles are considered lubricated for life when the vehicle is used for
normal service. See your ªService Guideº for Severe Duty requirements.
2If your engine coolant is green, use Ford Premium Cooling System
Fluid; if your coolant is orange, use Ford Extended Life Coolant. Refer to
Lubricant Specificationsfor part numbers and specification numbers.
