Weight-distributing Hitch - Vehicles without Automatic Leveling Suspension WARNING Do not adjust the spring bars so that your vehicle's rear bumper is higher than before attaching the trailer. Doing so will defeat the function of the weight-distributing hitch, which may cause unpredictable handling, and could result in serious personal injury. When hooking-up a trailer using a weight-distributing hitch, always use the following procedure: 1. Park the loaded vehicle, without the trailer, on a level surface. 2. Measure the height to the top of your vehicle's front wheel opening on the fender. This is H1. 3. Attach the loaded trailer to your vehicle without the weight-distributing bars connected. 4. Measure the height to the top of your vehicle's front wheel opening on the fender a second time. This is H2.

Weight-distributing Hitch - Vehicles with Automatic Leveling Suspension WARNING Do not adjust the spring bars so that your vehicle's rear bumper is higher than before attaching the trailer. Doing so will defeat the function of the weight-distributing hitch, which may cause unpredictable handling, and could result in serious personal injury. Note: If you do not move the loaded vehicle for approximately 12 hours, the leveling system may bleed down to a lower height. This can be especially apparent if you leave a trailer attached to the parked vehicle for long periods. You must drive your vehicle in order to re-level the suspension. When hooking-up a trailer using a weight-distributing hitch, always use the following procedure:

5. Install and adjust the tension in the weight-distributing bars so that the height of your vehicle's front wheel opening on the fender is approximately half the way down from H2, toward H1. 6. Check that the trailer is level or slightly nose down toward your vehicle. If not, adjust the ball height accordingly and repeat Steps 2-6. When the trailer is level or slightly nose down toward the vehicle: • Lock the bar tension adjuster in place. • Check that the trailer tongue securely attaches and locks onto the hitch. • Install safety chains, lighting and trailer brake controls as required by law or the trailer manufacturer.
