Towing

Safety Chains Note: Never attach safety chains to the bumper. Always connect the safety chains to the hook retainers of your vehicle hitch. To connect the trailer’s safety chains, cross them under the trailer tongue and allow enough slack for turning tight corners. Do not allow the chains to drag on the ground. Trailer Brakes (If Equipped) WARNING Do not connect a trailer's hydraulic brake system directly to your vehicle's brake system. Your vehicle may not have enough braking power and your chances of having a collision greatly increase. Electric brakes and manual, automatic or surge-type trailer brakes are safe if you install them properly and adjust them to the manufacturer's specifications. The trailer brakes must meet local and federal regulations.

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 mi (3 km) to re-level the suspension. 3. Park the loaded 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 loaded trailer to your vehicle without the weight-distributing bars connected. 6. Securely attach and lock the trailer tongue to the hitch. 7. Install safety chains, lighting and trailer brake controls as required by law or the trailer manufacturer. 8. Drive the vehicle and trailer at 20–25 mph (32–40 km/h) for approximately 2 mi (3 km) to re-level the suspension.

9. Park your vehicle and trailer on a level surface. 10. Measure the height to the top of your vehicle's front wheel opening on the fender a second time. This is H2. 11. 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. 12. Check that the trailer is level or slightly nose down toward your vehicle. If not, remove the trailer, adjust the ball height accordingly and repeat Steps 5-11. 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.
