FORD F150 2002 10.G Owners Manual

4WD Systems (if equipped)
4WD (when you select the 4WD mode), uses all four wheels to power
itself. This increases traction, enabling you to drive over terrain and road
conditions that a conventional two-wheel drive vehicle can't.
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 thoroughly familiar 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 momentary clunk and ratcheting
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, try to 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 steadily through the terrain. Apply the 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 capability may be 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 may stall.
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.
Water intrusion into the transmission may damage the
transmission.
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.

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
193

Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral, disengage
overdrive or manually shift to a
lower gear. When descending a
steep hill, avoid sudden hard
braking as you could lose control.
When you brake hard, the front
wheels can't turn and if they aren't
turning, you won't be able to steer.
The front wheels have to be turning in order to steer the vehicle. Rapid
pumping of the brake pedal will help you slow the vehicle and still
maintain steering control.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
ªpumpº the brakes.
Driving on snow and ice
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won't stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles for
stopping as well as drive slower than usual and consider using one of the
lower gears. In emergency stopping situations, avoid locking of the wheels.
Use a ªsqueezeº technique, push on the brake pedal with a steadily increasing
force which allows the wheels to brake yet continue to roll so that you may
steer in the direction you want to travel. If you lock the wheels, release the
brake pedal and repeat the squeeze technique. If your vehicle is equipped
with a Four Wheel Anti-Lock Brake System (ABS), apply the brake steadily.
Do not ªpumpº the brakes. Refer to theBrakessection of this chapter for
additional information on the operation of the anti-lock brake system.
Driving
194

Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Tires, Replacement Requirements
4WD vehicles are equipped with tires designed to provide for safe ride
and handling capability.
Do not use a size and type of tire and wheel other than that originally
provided by Ford because it can affect the safety and performance of
your vehicle, which could lead to loss of vehicle control or roll over and
serious injury. Make sure all tires and wheels on the vehicle are of the
same size, type, tread design, brand and load-carrying capacity. If you
have questions regarding tire replacement, see an authorized Ford or
Lincoln/Mercury dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford recommends, you should not use these tires for
highway driving.
If you use any tire/wheel combination not recommended by Ford, it may
adversely affect vehicle handling and could cause steering, suspension,
axle or transfer case failure.
Do not useºaftermarket lift kitsº or other suspension modifications,
whether or not they are used with larger tires and wheels.
These ªaftermarket lift kitsº could adversely affect the vehicle's handling
characteristics, which could lead to loss of vehicle control or roll over
and serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adversely affect the way your vehicle
handles. Do not exceed the Ford recommended pressure even if it is less
than the maximum pressure allowed for the tire.
Driving
195

Each day before 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 every few weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor overloaded.
Periodically inspect the tire treads and remove stones, nails, glass or
other objects that may be wedged in the tread grooves. Check for holes
or cuts that may permit 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 reasonably safe, predictable performance
whether loaded or empty and durable load carrying capability. For this
reason, Ford strongly recommends that you do not make modifications
such as adding or removing parts (such as lift kits or stabilizer bars) or
by using replacement parts not equivalent to the original factory
equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford recommends that caution be used with any vehicle equipped with a
high load or device (such as ladder racks or pickup box cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
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.
Driving
196

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.
