Weight-distributing Hitches

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.

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.

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

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.

Safety Chains

Note: Do not attach safety chains to the

bumper.

Always connect the safety chains to the

frame or hook retainers of your vehicle

hitch.

To connect the safety chains, cross the

chains under the trailer tongue and allow

enough slack for turning tight corners. Do

not allow the chains to drag on the ground.

Trailer Brakes

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.

The rating for the tow vehicle's braking

system operation is at the gross vehicle

weight rating, not the gross combined

weight rating.

Separate functioning brake systems

are required for safe control of towed

vehicles and trailers weighing more

than 1500 pounds (680 kilograms)

when loaded.
