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

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
Companyjoins 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 maymake it necessaryto travel diagonallyup
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
possiblyrolling 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.
When climbing a steep slope or hill,
start in a lower gear rather than
downshifting to a lower gear from a
higher gear once the ascent has
started. This reduces strain on the
engine and the possibilityof stalling.
If you do stall out, do not try to
turn around because you might roll
over. It is better to back down to a
safe location.
Applyjust enough power to the
wheels to climb the hill. Too much
power will cause the tires to slip,
spin or lose traction, resulting in
loss of vehicle control.

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.
Driving

•GAWR (Gross Axle Weight Rating):Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
SafetyCertification 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 bysubtracting the vehicle curb weight for each
engine/transmission combination, anyrequired 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 bysubtracting 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 SafetyCertification Label, located on the driver’s door pillar, lists
vehicle weight rating limitations. Before adding anyadditional equipment,
refer to these limitations.
Always ensure that the weight of occupants, cargo and equipment is
within the weight limitations, including both gross vehicle weight and
front and rear gross axle weight rating limits.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Exceeding anyvehicle weight rating limitation could result in
serious damage to the vehicle, loss of vehicle control, vehicle
rollover, and/or personal injury.
Do not use replacement tires with lower load carrying capacities than the
originals because theymaylower the vehicle’s GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.

Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
this chapter.
Loaded vehicles mayhandle differentlythan unloaded vehicles.
Extra precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavilyloaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people mayraise the center of gravityof the vehicle.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum GCWR chart (in theTrailer Towing
section in this chapter) for your type of engine and rear axle ratio.
2. Weigh your vehicle without cargo. To obtain correct weights, take your
vehicle to a shipping companyor an inspection station for trucks.
3. Subtract your loaded weight from the maximum GCWR in the chart.
This is the maximum trailer weight your vehicle can tow. It must be
below the maximum trailer weight shown in the chart.
TRAILER TOWING
Your vehicle maytow a Conventional/Class IV trailer or fifth wheel trailer
provided the maximum trailer weight is less than or equal to the
maximum trailer weight listed for your engine and rear axle ratio on the
following charts.
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 capacityis designated byweight, not byvolume, 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 carefullyprior to and after anytowing operation. The
following trailer towing charts applyto vehicles equipped with gasoline
engines; for Diesel engines, refer to the7.3 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.
