222 Towing 5. Install and adjust the tension in the weight distributing bars so that the height of the front fender is approximately halfway between H1 and H2. 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. Once 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. Weight-distributing Hitch - Vehicles with Automatic Leveling Suspension WARNING: Do not adjust a weight-distributing hitch to any position where the rear bumper of the vehicle is higher than it was 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 connecting a trailer to a vehicle with automatic leveling suspension using a weight-distributing hitch, always use the following procedure: 1. Load the interior of the vehicle to a weight similar to that which you intend to carry when towing. This includes things such as passenger weight and cargo. 2. Drive the vehicle for approximately 2 miles (3 kilometers) to re-level the suspension. 3. Park your vehicle, without the trailer, on a level surface. 4. Measure the height to the top of your vehicle's front wheel opening on the fender. This is H1. 5. Attach the trailer to your vehicle without the weight-distributing bars connected. 6. Make sure you securely attach and lock the trailer tongue to the hitch. 2014 Navigator (nav) Owners Guide gf, 1st Printing, June 2013 USA (fus)
