FORD 2009 F-150 v.2 - Manual (Page 309)

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.
