N (Neutral)
With the gearshift lever in N (Neutral), the vehicle can be started and is
free to roll. Hold the brake pedal down while in this position.
(Overdrive)
The normal driving position for the best fuel economy. Transmission
operates in gears one through four.
(Overdrive) can be deactivated
bypressing the transmission control switch on the end of the gearshift
lever. This will illuminate the O/D OFF lamp and activate Drive.
Drive (not shown)
Drive is activated when the transmission control switch is pressed.
•This position allows for all forward gears except overdrive.
•O/D OFF lamp is illuminated.
•Provides engine braking.
•Use when driving conditions cause excessive shifting from O/D to
other gears. Examples: citytraffic, hillyterrain, heavyloads, trailer
towing and when engine braking is required.
•To return to O/D (overdrive mode), press the transmission control
switch. The O/D OFF lamp will not be illuminated.
•O/D (Overdrive) is automaticallyreturned each time the keyis turned
off.
2 (Second)
This position allows for second gear only.
•Provides engine braking.
•Use to start-up on slipperyroads.
•To return to
(Overdrive), move the gearshift lever into the
(Overdrive) position.
•Selecting 2 (Second) at higher speeds will cause the transmission to
downshift to second gear at the appropriate vehicle speed.
1 (First)
•Provides maximum engine braking.
•Allows upshifts bymoving gearshift lever.
•Will not downshift into 1 (First) at high speeds; allows for 1 (First)
when vehicle reaches slower speeds.
Forced downshifts
•Allowed in
(Overdrive) or Drive.

•Depress the accelerator to the floor.
•Allows transmission to select an appropriate gear.
Shift strategy (4R100 automatic transmission)
To account for customer driving habits and conditions, your 4R100
automatic transmission electronicallycontrols the shift qualitybyusing
an adaptive learning strategy. The adaptive learning strategy is
maintained bypower from the battery. When the batteryis disconnected
or a new batteryis installed, the transmission must relearn its adaptive
strategy. Optimal shifting will resume within a few hundred kilometers
(miles) of operation.
If the shift quality does not improve within a few hundred
kilometers (miles) of operation, or if the downshifts and other
throttle conditions do not function normally, see your dealer or a
qualified service technician as soon as possible.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting from forward and reverse gears, stopping between shifts in a
steadypattern. Press lightlyon the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
MANUAL TRANSMISSION OPERATION (IF EQUIPPED)
Using the clutch
The manual transmission has a starter interlock that prevents cranking
the engine unless the clutch pedal is fullydepressed.
To start the vehicle:
1. Make sure the parking brake is fullyset.
2. Press the clutch pedal to the floor, then put the gearshift lever in the
neutral position.

3. Start the engine, then press the brake pedal and release the parking
brake.
4. Move the gearshift lever to the desired gear, then slowlyrelease the
clutch pedal while slowlypressing on the accelerator.
Do not drive with your foot resting on the clutch pedal or use the clutch
pedal to hold your vehicle at a standstill while waiting on a hill. These
actions will reduce the life of the clutch.
Recommended shift speeds
Downshift according to the following charts for your specific
engine/drivetrain combination:
Maximum downshift speeds1

3 - 2 32 km/h (20 mph) 13 km/h (8 mph)
2 - 1 8 km/h (5 mph) 3 km/h (2 mph)
1 - LO Onlyshift to LO when at a stop.
1Use 2H or 4H for 4WD equipped vehicles.2Downshift at lower speeds when driving on slipperysurfaces.
Reverse
1. Make sure that your vehicle is at a complete stop before you shift into
R (Reverse). Failure to do so maydamage the transmission.
2. Move the gearshift lever into the neutral position and wait at least
three seconds before shifting into R (Reverse).
•The gearshift lever can onlybe moved into R (Reverse) bymoving it
from left of 3 (Third) and 4 (Fourth) before shifting into R (Reverse).
This is a lockout feature that protects the transmission from
accidentallybeing shifted into R (Reverse) from

Shifting to/from 4L (4WD Low)
1. Bring the vehicle to a complete stop.
2. Depress the brake.
3. On vehicles equipped with an automatic transmission, place the
transmission in N (Neutral); on vehicles equipped with a manual
transmission, depress the clutch.
4. Move the transfer case lever through N (Neutral) directlyto the
desired position. The LOW RANGE indicator will illuminate once the
transfer case has engaged.
•If the transfer casedoes notengage, repeat steps 1 through 4.
Using the N (Neutral) position
The transfer case N (Neutral) position overrides the transmission
and puts the vehicle in neutral regardless of transmission
gearshift lever position. The vehicle can move forward or
backward.
This position should onlybe used when towing the vehicle.
Do not leave the vehicle unattended with the transfer case in the
N (Neutral) position. Always set the parking brake fully and turn
off the ignition when leaving the vehicle.

4X4 LOW (4WD Low)- Uses extra gearing to provide maximum power
to all four wheels. Intended onlyfor off-road applications such as deep
sand, steep grades or pulling heavyobjects. 4L (4WD Low) will not
engage while the vehicle is moving; this is normal and should be no
reason for concern. Refer toShifting to/from 4L (4WD Low)for proper
operation.
Shifting between 2WD (2WD High) and 4X4 HIGH (4WD High)
•Move the 4WD control between 2WD and 4X4 HIGH at anyforward
speed.
Note:Do not perform this operation at speeds above 72 km/h (45 mph)
if the outside temperature is below 0°C (32°F).
Note:Do not perform this operation if the rear wheels are slipping.
Shifting to/from 4X4 LOW (4WD Low)
1. Bring the vehicle to a complete stop
2. Depress the brake
3. On vehicles equipped with an automatic transmission, place the
transmission in N (Neutral); on vehicles equipped with a manual
transmission, depress the clutch.
4. Move the 4WD control to the desired position.
•If shifting into 4X4 LOW (4WD Low), wait for the LOW RANGE light
in the instrument cluster to turnonindicating the shift is complete.
•If shifting out of 4X4 LOW (4WD Low), wait for the LOW RANGE light
in the instrument cluster to turnoffindicating the shift is complete.
Driving off-road with truck and utility vehicles
4WD vehicles are speciallyequipped for driving on sand, snow, mud and
rough terrain and have operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
How your vehicle differs from other vehicles
Truck and utilityvehicles can differ from some other vehicles. Your
vehicle maybe higher to allow it to travel over rough terrain without
getting hung up or damaging underbodycomponents.
The differences that make your vehicle so versatile also make it handle
differentlythan an ordinarypassenger car.
Maintain steering wheel control at all times, especiallyin rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.

If your vehicle gets stuck
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting between forward and reverse gears, stopping between shifts, in a
steadypattern. Press lightlyon the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fullyreleased, but the brake warning lamp
remains illuminated, the brakes maynot be working properly.
See your dealer or a qualified service technician.
Do not spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
Emergency maneuvers
•In an unavoidable emergencysituation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
turn the steering wheel onlyas rapidlyand as far as required to avoid
the emergency. Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergencystop, avoid skidding the tires and do not
attempt anysharp steering wheel movements.

Vehicles with a higher center of gravitysuch as utilityand
four-wheel drive vehicles handle differentlythan vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars anymore
than low-slung sports cars are designed to perform satisfactorilyunder
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiouslycould result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injuryand death.
•If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the waythe vehicle
responds to a maneuver (steering, acceleration or braking). Again,
avoid these abrupt inputs.
Parking
On some 4WD vehicles, when the transfer case is in the N (Neutral)
position, the engine and transmission are disconnected from the rest of
the driveline. Therefore, the vehicle is free to roll even if the automatic
transmission is in P (Park) or the manual transmission is in gear. Do not
leave the vehicle unattended with the transfer case in the N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.
4WD Systems
4WD (when you select a 4WD mode), uses all four wheels to power the
vehicle. This increases traction, enabling you to drive over terrain and
road conditions that a conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels
through a transfer case. On 4WD
vehicles, the transfer case allows
you to select 4WD when necessary.
Information on transfer case
operation and shifting procedures
can be found in theDriving
chapter. Information on transfer
case maintenance can be found in theMaintenance and specifications
chapter. You should become thoroughlyfamiliar with this information
before you operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 while
the vehicle is moving can cause some momentaryclunk and ratcheting
Driving
119

sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Sand
When driving over sand, tryto keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadilythrough the terrain. Applythe accelerator slowly
and avoid spinning the wheels.
If you must reduce the tire pressure for whatever reason in sand, make
sure you re-inflate the tires as soon as possible.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.
Mud and water
If you must drive through high
water, drive slowly. Traction or
brake capabilitymaybe limited.
When driving through water,
determine the depth; avoid water
higher than the bottom of the hubs
(if possible) and proceed slowly. If
the ignition system gets wet, the
vehicle maystall.
Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectivelyas drybrakes. Drying can be improved bymoving
your vehicle slowly while applying light pressure on the brake pedal.
Be cautious of sudden changes in vehicle speed or direction when you
are driving in mud. Even 4WD vehicles can lose traction in slick mud. As
when you are driving over sand, applythe accelerator slowlyand avoid
spinning your wheels. If the vehicle does slide, steer in the direction of
the slide until you regain control of the vehicle.
If the transmission, transfer case or front axle are submerged in water,
their fluids should be checked and changed, if necessary.
Driving through deep water may damage the transmission.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
If the front or rear axle is submerged in water, the axle lubricant should
be replaced.
Driving

Each daybefore you drive, check
your tires. If one looks lower than
the others, use a tire gauge to check
pressure of all tires, and adjust if
required. Check tire pressure with a
tire gauge everyfew weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor a vehicle which is
overloaded.
Periodicallyinspect the tire treads and remove stones, nails, glass or
other objects that maybe wedged in the tread grooves. Check for holes
or cuts that maypermit air leakage from the tire and make necessary
repairs.
Inspect the tire side walls for cuts, bruises and other damage. If internal
damage to the tire is suspected, have the tire demounted and inspected
in case it needs to be repaired or replaced.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide both reasonablysafe, predictable performance
whether loaded or emptyand durable load carrying capability. For this
reason, Ford Motor Companystronglyrecommends that you do not make
modifications such as adding or removing parts (such as lift kits or
stabilizer bars) or byusing replacement parts not equivalent to the
original factoryequipment.
Anymodifications to a vehicle that raise the center of gravitycan make
it more likelythe vehicle will roll over as a result of a loss of control.
Ford Motor Companyrecommends that caution be used with anyvehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properlymayvoid the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adverselyaffect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavyoff-road usage.
POWER TAKE OFF (PTO) CAPABILITY (IF EQUIPPED)
Some vehicles maybe equipped with Power Take Off (PTO) capability.
These vehicles have a special transmission case, internal components and
calibration for PTO usage.
Driving
124
Page 125 of 256

The PTO can be used during mobile and stationary
continuous/intermittent applications.
PTO operation is disabled while the vehicle is in Overdrive (the TCIL will
not be illuminated), in N (Neutral), during engine cranking. Transmission
upshift and downshift schedules will be reduced byabout 15% and will
have a firmer shift feel during PTO mobile applications.
The PTO cannot be disabled while the transmission is in D (Drive)
(Overdrive position with Overdrive canceled), 2 (Second) or 1 (First).
Refer to theBody Builder’s Layout Bookfor recommended electrical
installation.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowlyespeciallyif the depth is not known. Never drive through water
that is higher than the bottom of the hubs (for trucks) or the bottom of
the wheel rims (for cars). Traction or brake capabilitymaybe limited
and your vehicle maystall. Water mayalso enter your engine’s air intake
and severelydamage your engine.
Once through the water, always drythe brakes bymoving your vehicle
slowlywhile applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quicklyas drybrakes.Driving through deep
water where the transmission vent tube is submerged may allow
water into the transmission and cause internal transmission
damage.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
•Base Curb Weight:Weight of the vehicle including anystandard
equipment, fluids, lubricants, etc. It does not include occupants or
aftermarket equipment.
•Payload:Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
•GVW (Gross Vehicle Weight):Base curb weight plus payload
weight.
•GVWR (Gross Vehicle Weight Rating):Maximum allowable total
weight of the base vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed on the Safety
Certification Label on the driver’s door pillar.
