Driving 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. • do not allow waves to break higher than 6 inches (15 cm) above the bottom edge of the rear bumper. Exceeding these limits may allow water to enter vehicle components: • causing internal damage to the components. • affecting driveability, emissions and reliability. Replace the rear axle lubricant any time the axle has been submerged in water. Rear axle lubricant quantities are not to be checked or changed unless a leak is suspected or repair required. RECREATIONAL TOWING (ALL WHEELS ON THE GROUND) An example of recreational towing would be towing your vehicle behind a motorhome. Follow these guidelines if you have the need for recreational towing your vehicle with all four wheels on the ground. These guidelines are designed to ensure that your transmission is not damaged. 2WD vehicles: • Place the transmission in N (Neutral) • Maximum speed is 35 mph (56 km) • Maximum distance is 50 miles (80 km) If a distance of 50 miles (80 km) or a speed of 35 mph (56 km) must be exceeded, the drive shaft will have to be removed before the vehicle is towed. Ford recommends the driveshaft be removed/installed only by a qualified technician. See your local dealer for driveshaft removal/installation. Improper removal/installation of the driveshaft can cause transmission fluid loss, damage to the driveshaft and internal transmission components. 4WD vehicles electronic shift transfer case: 4x4 vehicles with electronic shift on the fly cannot be towed with any wheels on the ground. 189 2004 F150 (f12) Owners Guide (post-2002-fmt) USA English (fus)
