Tires, Wheels and Loading 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. 171 2011 Crown Victoria (cro) Owners Guide, 1st Printing USA (fus)
