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 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. 2WD and 4WD vehicles: 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. See your authorized dealer if you must flat-tow a vehicle equipped with the Control Trac௡ 4WD system. In case of a roadside emergency with a disabled vehicle, see Wrecker towing in the Roadside Emergencies chapter. 222 2012 Navigator (nav) Owners Guide, 1st Printing USA (fus)
