Here are some important things to consider before you do recreational vehicle towing: Dinghy Towing Two-Wheel-Drive Vehicles Notice: If you tow your vehicle with all four wheels on the ground, the drivetrain components could be damaged. The repairs would not be covered by your warranty. Do not tow your vehicle with all four wheels on the ground. Two-wheel-drive vehicles should not be towed with all four wheels on the ground. Two-wheel-drive transmissions have no provisions for internal lubrication while being towed. To properly tow these vehicles, they should be placed on a platform trailer. • What's the trailering capacity of the towing vehicle? Be sure you read the tow vehicle manufacturer's recommendations. • How far will you tow? Some vehicles have restrictions on how far and how long they can be towed. • Do you have the proper towing equipment? See your dealer or trailering professional for additional advice and equipment recommendations. • Is your vehicle ready to be towed? Just as you would prepare your vehicle for a long trip, you'll want to make sure your vehicle is prepared to be towed. See Before Leaving on a Long Trip on page 4-37. 4-51
