If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
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.
Do not spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.
Emergency maneuvers
²In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid ªover-drivingº 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. Use all
available road surface to return the vehicle to a safe direction of
travel.
²In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
²If 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 barking). 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 N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.

ªTread Lightlyº is an educational
program designed to increase public
awareness of land-use regulations
and responsibilities in our nations
wilderness areas. Ford 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
ªtreading lightly.º
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.
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 possibility of 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.
Apply just 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.

DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine's air intake and severely damage your engine.
If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the 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.
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:
²Base Curb Weight:Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include occupants or
aftermarket equipment.
²Payload:Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
²GVW (Gross Vehicle Weight):Base curb weight plus payload
weight. The GVW is not a limit or a specification.
²GVWR (Gross Vehicle Weight Rating):Maximum permissable 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.
²GAWR (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.
²GCW (Gross Combined Weight):The combined weight of the
towing vehicle (including occupants and cargo) and the loaded trailer.
²GCWR (Gross Combined Weight Rating):Maximum permissable
combined weight of towing vehicle (including occupants and cargo)
and the loaded trailer
Driving
197

²Maximum 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.
²Maximum 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.
²Trailer Weight Range:Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
The Safety Certification Label, found on the driver's door pillar, lists
several important vehicle weight rating limitations. Before adding any
additional equipment, refer to these limitations. If you are adding weight
to the front of your vehicle, (potentially including weight added to the
cab), the weight added should not exceed the front axle reserve capacity
(FARC). Additional frontal weight may be added to the front axle reserve
capacity provided you limit your payload in other ways (i.e. restrict the
number of occupants or amount of cargo carried).
Always ensure that the weight of occupants, cargo and equipment being
carried is within the weight limitations that have been established for
your vehicle including both gross vehicle weight and front and rear gross
axle weight rating limits. Under no circumstance should these limitations
be exceeded.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle and/or personal injury.

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, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling cargo and people may raise the center of gravity of the vehicle.
Calculating the load your vehicle can carry/tow
1.
Use the appropriate maximum gross combined weight rating (GCWR)
chart to find the maximum GCWR for your type engine and rear axle ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum trailer weight your vehicle can tow
and must fall below the maximum shown under maximum trailer weight
on the chart.
TRAILER TOWING
Your vehicle may tow a class I, II or III 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.
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 periodically during, and after any towing operation.
Exceeding the maximum GCWR could result in extensive damage
to your vehicle and personal injury.
Driving
199

Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight could result in engine damage, transmission/axle damage,
structural damage, loss of control, and personal injury.
