Tires, Wheels and Loading Launching or retrieving a boat Disconnect the wiring to the trailer before backing the trailer into the water. Reconnect the wiring to the trailer after the trailer is removed from the water. 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 Follow these guidelines if you have a need for recreational (RV) towing. An example of recreational towing would be towing your vehicle behind a motorhome. These guidelines are designed to ensure that your transmission is not damaged. Note: Put your climate control system in recirculated air mode to prevent exhaust fumes from entering the vehicle. Refer to the Climate Controls chapter for more information. 262 2010 F-250/350/450/550 (f23) Owners Guide, 2nd Printing USA (fus)
