2009 Dodge Grand Caravan Owner's Manual - Page 404

402 STARTING AND OPERATING • When hauling cargo or towing a trailer, do not overload your vehicle or trailer. Overloading can cause a loss of control, poor performance or damage to brakes, axle, engine, transaxle, steering, suspension, chassis structure or tires. • Safety chains must always be used between your vehicle and trailer. Always connect the chains to the frame or hook retainers of the vehicle hitch. Cross the chains under the trailer tongue and allow enough slack for turning corners. • Vehicles with trailers should not be parked on a grade. When parking, apply the parking brake on the tow vehicle. Put the tow vehicle automatic transmission in PARK. Always, block or chock the trailer wheels. • GCWR must not be exceeded. • Total weight must be distributed between the tow vehicle and the trailer such that the following four ratings are not exceeded: 1. GVWR 2. GTW 3. GAWR 4. Trailer tongue weight rating for that trailer hitch. (This requirement may limit the ability to always achieve the 10% to 15% range of trailer tongue weight as a percentage of total trailer weight.)
