Weight-Distributing Hitches and Weight Carrying Hitches Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Always leave just enough slack so you can turn with your rig. Never allow safety chains to drag on the ground. Trailer Brakes If your trailer weighs more than 2,000 lbs (900 kg) loaded, then it needs its own brakes - and they must be adequate. Be sure to read and follow the instructions for the trailer brakes so you'll be able to install, adjust and maintain them properly. (A) Body-to-Ground Distance (B) Front of Vehicle When using a weight-distributing hitch, the hitch must be adjusted so that the distance (A) remains the same both before and after coupling the trailer to the tow vehicle. If you'll be pulling a trailer that, when loaded, will weigh more than 5,000 lbs (2 270 kg) be sure to use a properly mounted weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when driving. You should always use a sway control if your trailer will weigh more than these limits. You can ask a hitch dealer about sway controls. Since your vehicle is equipped with the StabiliTrak® system, your trailer brake system cannot tap into the vehicle's hydraulic brake system. 4-69
