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.
Driving through deep water 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.

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
For F-150 snowplow applications, Ford recommends the F-150 4x4
Regular Cab and SuperCab equipped with the 5.4L engine, Heavy Duty
Payload Package and Snow Plow Prep Package. The Heavy Duty Payload
Package for 4x4 includes unique powertrain control strategy, required for
engine cooling when the raised snowplow blade blocks radiator airflow in
highway driving. Factory installed snow plow prep package vehicles
already have been programmed with the unique power train control
strategy to provide proper cooling. If the vehicle is being upgraded to the
equivalent hardware set as the snow plow prep package, then the vehicle
can obtain the unique power train control strategy to provide proper
cooling by getting service at an authorized dealer. The powertrain control
strategy required for snowplowing to provide proper cooling may
increase fan noise that may also be noticed under conditions other than
snow plowing. F-150 SuperCrew, Limited and Harley-Davidson F-150 are
not recommended for snowplowing and the Snow Plow Prep Package is
not available.

Installing the snowplow
Weight limits and guidelines for selecting and installing the snowplow can
be found in the Ford 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 anAlterer’s
Labelon 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 Certification Label. 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 Ford Workshop
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
Operating the vehicle with the snowplow attached
Ford recommends that the F–150 be limited to low speed, personal-use
snow removal. 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.
Snowplowing with your airbag equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
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 air bag 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.
Transmission operation while plowing
•Shift transfer case to 4L (4WD Low) when plowing in small areas at
speeds below 5 mph (8 km/h).
•Shift transfer case to 4H (4WD 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.
Do not rock the vehicle if the engine is not at operating
temperature. Do not rock the vehicle for more than a minute. The
transmission and tires may be damaged or the engine may
overheat.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:The tire pressure monitoring system (TPMS) indicator light will
illuminate when the spare tire is in use. To restore the full functionality
of the monitoring system, all road wheels equipped with tire pressure
monitoring sensors must be mounted on the vehicle.
