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 in (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. Do not tow your vehicle with any wheels on the ground, as vehicle or transmission damage may occur. It is recommended to tow your vehicle with all four (4) wheels off the ground such as when using a car-hauling trailer. Otherwise, no recreational towing is permitted. In case of a roadside emergency with a disabled vehicle, see Wrecker towing in the Roadside Emergencies chapter. 192 2010 Econoline (eco) Owners Guide, 3rd Printing USA (fus)
