Driving 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. 308 2009 F-150 (f12) Owners Guide (own2002), 3rd Printing USA (fus)
