You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. To maintain
steering and braking control of your vehicle, you must have all four
wheels on the ground and they must be rolling, not sliding or spinning.
Basic operating principles
Maintain steering wheel control at all times, especially in rough terrain;
sudden changes in terrain can result in abrupt steering wheel motion. Do
not use 4WD on dry, hard surfaced roads (except models equipped with
Auto 4WD).
If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or rollover. Remember, your safety and the
safety of others should be your primary concern.
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
The vehicle 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.

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.
Normal characteristics
On some 4WD vehicles, the initial shift from two-wheel drive to
four–wheel drive while the vehicle is moving can cause some momentary
clunk and ratcheting sounds. This is normal and should be no cause for
concern.
Driving on sand, mud and water
When driving over sand, avoid reducing the tire pressures; instead, shift
to a lower gear. Apply the accelerator slowly and avoid spinning the
wheels. If you must reduce the tire pressure, make sure you re-inflate
the tires as soon as possible. Avoid excessive speed because vehicle
momentum can work against your vehicle and cause it to become stuck.
If you must drive through high
water, drive slowly. Traction or
braking ability may be reduced.
Also, if the ignition system gets wet,
the vehicle may stall.
Once you’re 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.
When driving through mud, be cautious of sudden changes in vehicle
speed or direction. Even 4WD vehicles can lose traction in slick mud.
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 either axle
become submerged in mud or water, their fluids should be checked and
changed, if necessary. After driving through mud, clean off residue stuck
to rotating driveshafts and tires. Excess mud stuck on tires and rotating
driveshafts could damage driveline components.

Driving on snow and ice
4WD vehicles can skid like any other vehicle. If you start to skid while
driving on a snowy or icy road, turn the steering wheel in the direction
of the slide until you regain control. Although a 4WD vehicle may
accelerate better than a two-wheel drive vehicle in snow and ice, it won’t
stop any faster.
Don’t press hard on the accelerator or brake pedal or make quick
steering changes while on snow or ice. Apply the accelerator slowly and
steadily when starting from a full stop. If your vehicle is equipped with
ABS, apply the brake steadily. Do not “pump” the brakes. Refer to the
Brakessection of this chapter for additional information on the
operation of the anti-lock brake system. If your vehicle is not equipped
with ABS, use a “squeeze” braking 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.
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.
Maintenance and Modifications
Ford strongly recommends that you do not add or remove steering or
suspension parts (such as lift kits or stabilizer bars) or by using
replacement parts not equivalent to the original factory equipment. Do
not use aftermarket “lift kits” or other suspension modifications. These
could adversely affect the vehicle’s handling characteristics, which could
lead to loss of vehicle control or roll over and serious injury. Frequent
inspection of vehicle chassis components is recommended if the vehicle
is subjected to heavy off-road usage.
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.
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 any vehicle 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 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.
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 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 can 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 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 company or 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
Trailer towing puts additional loads on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. For your safety and to
maximize vehicle performance, be sure to use the proper equipment
while towing.
Follow these guidelines to ensure safe towing:
•Stay within your vehicle’s load limits.
•Thoroughly prepare your vehicle for towing. Refer toPreparing to
towin this chapter.
•Use extra caution when driving with a trailer. Refer toDriving while
you towin this chapter.
•Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
•Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
•Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter. Remember to figure in the tongue
load of your loaded vehicle when figuring the total weight. Tongue load
should not exceed 10% of the loaded trailer.

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.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that 10% of
the total weight of the trailer is on the tongue.
Use a frame-mounted weight distributing hitch for trailers over
1,588 kg (3,500 lb).
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.Do
not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications.
Do not connect a trailer’s hydraulic brake system directly to your
vehicle’s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the towing vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Make sure your trailer lamps conform to local and Federal regulations.
See your dealer or trailer rental agency for proper instructions and
equipment for hooking up trailer lamps.
