Night time and dark area use
At night time or in dark areas, the camera system relies on the reverse
lamp lighting to produce an image. Therefore it is necessary that both
reverse lamps are operating in order to get a clear image in the dark. If
either of the lamps are not operating, stop using the camera system, at
least in the dark, until the lamp(s) are replaced and functioning.
Servicing
•If the image comes on while the vehicle is not in R (Reverse), have
the system inspected by your authorized dealer.
•If the image is not clear, then check if there is anything covering the
lens such as dirt, mud, ice, snow, etc. If the image is still not clear
after cleaning, have your system inspected by your authorized dealer.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING:For important information regarding safe operation
of this type of vehicle, seePreparing to drive your vehiclein
this chapter.
When four–wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD can be selected when additional
driving power is desired.
4WD operation is not recommended on dry pavement. Doing so could
result in difficult disengagement of the transfer case, increased tire wear
and decreased fuel economy.
Manual Shift On Stop (MSOS) 4x4 system (if equipped)
The 4WD system is engaged or
disengaged by rotating the control
for both front wheel hub locks from
the FREE or LOCK position, then
manually engaging or disengaging
the transfer case with the
floor-mounted shifter. For increased
fuel economy in 2WD, rotate both
hub locks to the FREE position.
•For proper operation, make
sure that each hub is fully
engaged and that both hub locks are set to the same position
(both set to LOCK or both set to FREE). To engage LOCK,

Using a Manual Shift On Stop (MSOS) 4x4 system (if equipped)
Note: High shift efforts may be encountered when attempting to
shift into and out of 4x4 modes. It is recommended to allow the
vehicle to roll at a speed below 3 mph (5 km/h) when shifting
between modes.
Note:Some noise may be heard as the 4x4 system shifts or engages.
This is normal. In order to reduce engagement noise, it is recommended
that all shifts be performed at speeds below 3 mph (5 km/h).
2H (2WD)– For general on-road driving. Sends power to the rear
wheels only should be used for street and highway driving. Provides
optimal smoothness and fuel economy at high speeds.
4H (4x4 High)– Used for extra traction such as in snow or icy roads or
in off road situations.This mode is not intended for use on dry
pavement.
N (Neutral)– Only used when towing the vehicle. No power to front or
rear wheels.

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.
WARNING:Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Refer toGaugesin theInstrument Clusterchapter 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.
WARNING: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 arenotdesigned 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.

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.
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.
Note:If air is released from your tires, the Tire Pressure Monitoring
System (TPMS) indicator light may illuminate (if equipped).
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.
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.
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.

Ford Super Duty Vehicles are qualified for use as a stationary or mobile
power source, within limits detailed in theFord Truck Body Builders
Layout Book,found at www.fleet.ford.com/truckbbas, and through the
Ford Truck Body Builders Advisory Service.
For stationary PTO operation of extended duration (beyond 10 minutes),
diesel engine is recommended. Further consult your aftermarket PTO
installer, since the duration of operation limit for the aftermarket PTO
may be less than the vehicle is capable of.
DRIVING THROUGH WATER
If driving through deep or standing
water is unavoidable, proceed very
slowly especially when the depth is
not known. Never drive through
water that is higher than the bottom
of the wheel rims (for cars) or the
bottom of the hubs (for trucks).
When driving through water, traction or brake capability may be limited.
Also, water may enter your engine’s air intake and severely damage your
engine or your vehicle may stall.Driving through deep water where
the transmission vent tube is submerged may allow water into the
transmission and cause internal transmission damage.
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.
SNOWPLOWING
Ford recommends that the Super Duty F-Series used for snow removal
include the Snow Plow Package Option.
Installing the snowplow
Weight limits and guidelines for selecting and installing the snowplow can
be found in theFord Truck Body Builders Layout Book,Snowplow
section, found at www.fleet.ford.com/truckbbas. A typical installation
affects the following:
•Certification to government safety laws such as occupant protection
and airbag deployment, braking, and lighting. Look for an “Alterer’s
Label” on the vehicle from the snowplow installer certifying that the
installation meets all applicable Federal Motor Vehicle Safety
Standards (FMVSS).

•The Total Accessory Reserve Capacity (TARC) is shown on the lower
right side of the vehicle’s Safety Compliance Certification Label. This
applies to Ford-completed vehicles of 10,000 lb. (4,536 kg) GVWR or
less. This is the weight of permanently-attached auxiliary equipment,
such as snowplow frame-mounting hardware, that can be added to the
vehicle and satisfy Ford compliance certification to FMVSS. Exceeding
this weight may require the auxiliary equipment installer additional
safety certification responsibility. The Front Accessory Reserve
Capacity (FARC) is added for customer convenience.
•Rear ballast weight behind the rear axle may be required to prevent
exceeding the FGAWR, and provide front-to-rear weight balance for
proper braking and steering.
•Front wheel toe may require re-adjustment to prevent premature
uneven tire wear. Specifications are found in the FordWorkshop
Manual.
•Headlight aim may require re-adjustment.
•The tire air pressures recommended for general driving are found on
the vehicle’s Safety Certification Label. The maximum cold inflation
pressure for the tire and associated load rating is imprinted on the tire
sidewall. Tire air pressure may require re-adjustment within these
pressure limits to accommodate the additional weight of the snowplow
installation.
•Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your authorized dealer for
additional information.
Operating the vehicle with the snowplow attached
Do not use your vehicle for snow removal until it has been driven at
least 500 miles (800 km).
The attached snowplow blade restricts airflow to the radiator, and may
cause the engine to run at a higher temperature: Attention to engine
temperature is especially important when outside temperatures are
above freezing. Angle the blade to maximize airflow to the radiator and
monitor engine temperature to determine whether a left or right angle
provides the best performance.
Follow the severe duty schedule in yourscheduled maintenance
informationfor engine oil and transmission fluid change intervals.

Snowplowing with your airbag-equipped vehicle
Your vehicle is equipped with a driver and passenger airbag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the airbag. Such driving also
increases the risk of accidents.
WARNING:All occupants of the vehicle, including the driver,
should always properly wear their safety belts, even when an air
bag supplemental restraint system (SRS) is provided.
Never remove or defeat the “tripping mechanisms” designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible airbag deployment.
WARNING:Do not attempt to service, repair, or modify the air
bag supplemental restraint system (SRS) or its fuses. See your
Ford or Lincoln Mercury dealer.
WARNING:Additional equipment such as snowplow equipment
may effect the performance of the airbag sensors increasing the
risk of injury. Please refer to theBody Builders Layout Bookfor
instructions about the appropriate installation of additional equipment.
Transmission operation while plowing
Operate the vehicle with the automatic transmission gearshift lever in
the D (Overdrive) position and tow/haul off.
•Shift transfer case to 4L (4x4 Low) when plowing in small areas at
speeds below 5 mph (8 km/h).
•Shift transfer case to 4H (4x4 High) when plowing larger areas or light
snow at higher speeds. Do not exceed 15 mph (24 km/h).
•Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
•If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
