1999 FORD F250 SUPER DUTY wheel

Driving through deep water where the transmission is submerged
may allow water into the transmission and cause internal
transmission damage.
TOWING A TRAILER
Your vehicle may tow 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.
Weight of additional “body” must be
subtracted from the maximum
trailer weight.
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 after any towing operation.
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.

Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your Scheduled Maintenance guide
for more information.
Trailer towing tips
•Practice turning, stopping and backing up in an area before starting on
a trip to get the feel of the vehicle trailer combination. When turning,
make wider turns so the trailer wheels will clear curbs and other
obstacles.
•Allow more distance for stopping with a trailer attached.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) (automatic transmissions) or N (Neutral)
(manual transmissions). This aids engine cooling and air conditioner
efficiency.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
When backing down a ramp during boat launching or retrieval,
•Do not allow the static water level to rise above the bottom edge of
the rear bumper and
•Do not allow waves to break higher than 15 cm (six inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions and reliability.
Replace front and rear axle lubricants anytime the axles have been
submerged in water. Axle lubricant quantities are not to be checked
unless a leak is suspected.
Recreational towing
If you may want to tow your vehicle behind another vehicle, such as an
RV, follow these guidelines:
Driving
140

•4x2 vehicles must have the driveshaft removed if the rear wheels are
to be kept on the ground. If only the front wheels will be on the
ground, the driveshaft does not need to be removed.
•4x4 Electronic Shift on the Fly vehicles cannot be towed with any
wheels on the ground.
•
4x4 vehicles with a manual shift (floor-mounted) transfer case shifter
must have the transfer case and transmission gearshift levers placed in
the N (Neutral) position in order to tow with all wheels on the ground.
SNOWPLOWING
For low speed snow removal, Ford offers a Snowplow Package as an
option. If you do not have this equipment, do not use your vehicle as a
snowplow or powertrain and suspension system damage may occur.
Do not install a snowplow and plow with your vehicle until it has been
driven at least 800 km (500 miles).
Installing snowplow
Read the following instructions before installing a snowplow:
•Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find Front GAWR.
•The Front Axle Accessory Reserve Capacity and the Total Accessory
Reserve Capacity listed on the bottom right of the Safety Compliance
Certification Label will determine whether or not the addition of a
snowplow will overload your vehicle.
•The weight of the snowplow and supporting components distributed to
the front axle must not exceed the front accessory reserve capacity.
•The total weight of the snowplow and aftermarket equipment must
not exceed the Total Accessory Reserve Capacity.
•The weight of the installed snowplow and aftermarket equipment must
not load the vehicle beyond the GAWR (front/rear) and GVWR listed
on the Safety Compliance Certification Label.
•The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the Gross
Combined Weight Rating (GCWR) for towing.
•Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.

Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln-Mercury dealer.
Engine temperature while plowing
When driving with a plow, your
engine may run at a higher
temperature than normal because
the attached snowplow blade will
restrict airflow to the radiator.
If you are driving more than 24 km (15 miles) at temperatures above
freezing, angle the plow blade either full left or full right to provide
maximum airflow to the radiator.
If you are driving less than 24 km (15 miles) at speeds up to 64 km/h
(40 mph) in cold weather, you will not need to worry about blade
position to provide maximum airflow.
4WD operation while plowing
•Shift transfer case to 4x4 LOW (4WD Low) when plowing in small
areas at speeds below 8 km/h (5 mph).
•
Shift transfer case to 4x4 HIGH (4WD High) when plowing larger areas
or light snow at higher speeds. Do not exceed 24 km/h (15 mph).
•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.
Do not spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
