Shifting from 2WD (2WD High) to 4x4 HIGH (4WD High)
Rotate the 4WD control to the 4x4
HIGH position at speeds up to 88
km/h (55 mph).
•The electronic shift 4WD
system is designed to engage
4x4 HIGH (4WD High) when
the vehicle is moving. If
shifted to 4x4 HIGH (4WD
HIGH) while at complete stop,
4x4 may not engage and the
4x4 indicator may not
illuminate until the vehicle is driven above 8 km/h (5 mph).
•Do not shift into 4x4 HIGH with the rear wheels slipping.
Shifting from 4x4 HIGH (4WD High) to 2WD (2WD High)
Rotate the 4WD control to 2WD at
any forward speed. Disengagement
of the transfer case and front hubs
may be delayed due to torque bind
which is caused by driving on dry
hard surfaces or performing tight
turns while using the 4WD system.
•Yo udo notneed to operate the vehicle in R (Reverse) to disengage
your front hubs, but it will eliminate any torque bind and allow the
system to immediately disengage.
Shifting from 4x4 HIGH (4WD High) to 4x4 LOW (4WD Low)
1. Bring the vehicle to a complete stop.
2. Depress the brake.
3. Place the gearshift in N (Neutral) (automatic transmission) or depress
the clutch (manual transmission).

Driving off-road with truck and utility vehicles
4WD vehicles are specially equipped 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 utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
The differences that make your vehicle so versatile also make it handle
differently than an ordinary passenger car.

Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed 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, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
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
steady pattern. Press lightly on 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 fully released, but the brake warning lamp
remains illuminated, the brakes may not 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 emergency situation where a sudden sharp turn
must be made, remember to avoid“over-driving”your vehicle, i.e.,
turn the steering wheel only as rapidly and 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 emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed 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, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and 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 way the 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.

Once through water, always try the brakes. Wet brakes do not stop the
vehicle as effectively as dry brakes. Drying can be improved by moving
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, apply the accelerator slowly and 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.
After driving through mud, clean off residue stuck to rotating driveshafts
and tires. Excess mud stuck on tires and rotating driveshafts causes an
imbalance that could damage drive components.
“Tread Lightly”is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford Motor
Company joins the U.S. Forest Service and the Bureau of Land
Management in encouraging you to help preserve our national forest and
other public and private lands by“treading lightly.”
Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down.Avoid driving crosswise or turning on steep
slopes or hills. A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.

and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
Power take off (PTO) capability (if equipped)
Some vehicles are equipped with Power Take Off (PTO) capability. These
vehicles have a special transmission case, internal components and
calibration for PTO usage.
The PTO can be used during mobile and stationary
continuous/intermittent applications.
Gasoline engine:
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 by about 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.
Diesel engine:
The Auxiliary Powertrain Control Module (APCM) will elevate the engine
speed to 1,200 RPM when in PTO mode. PTO operation will be disabled
in stationary drive idle conditions. For more information on the APCM
and PTO operation with the Diesel engine, refer to the APCM manual
supplied with your vehicle.
DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially if 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 capability may be limited
and your vehicle may stall. Water may also enter your engine’s air intake
and severely damage your engine.
Once through the water, always dry the brakes by moving your vehicle
slowly while applying light pressure on the brake pedal. Wet brakes do
not stop the vehicle as quickly as dry brakes.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 any standard
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.
•GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Safety Certification Label on the driver’s door pillar.
•GCW (Gross Combined Weight):The combined weight of the
towing vehicle (including occupants and cargo) and the loaded trailer.
•GCWR (Gross Combined Weight Rating):Maximum allowable
combined weight of towing vehicle (including occupants and cargo)
and the loaded trailer.
•Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
•Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle (including occupants and cargo) is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
•Trailer Weight Range:Specified range of trailer weight from zero to
the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
The Safety Certification Label, located on the driver’s door pillar, lists
vehicle weight rating limitations. Before adding any additional equipment,
refer to these limitations.
Driving

2nd unit bodies are not included in maximum trailer weight ratings. The
weight of the additional“body”must be subtracted from the maximum
trailer weight.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully prior to and after any towing operation. The
following trailer towing charts apply to vehicles equipped with gasoline
engines; for Diesel engines, refer to the6.0 Liter Power Stroke Direct
Injection Turbo Diesel Supplement.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.
