Weight-distributing hitch

When hooking-up a trailer using a weight-distributing hitch, always use

the following procedure:

1. Park the vehicle (without the trailer) on a level surface.

2. Measure the height of the top of the front wheel opening on the

fender, this is H1.

3. Attach the trailer to the vehicle without the weight distributing bars

connected.

4. Measure the height of the top of the 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 the front fender is approximately halfway between H1 and

H2.

6. Check that the trailer is level. If not level, adjust the ball height

accordingly and repeat Steps 3–6.

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.

Safety chains

Always connect the trailer’s safety chains to the frame or hook retainers

of the vehicle hitch. To connect the trailer’s safety chains, cross the

chains under the trailer tongue and allow slack for turning corners.

If you use a rental trailer, follow the instructions that the rental agency

gives to you.

Do not attach safety chains to the bumper.

Trailer brakes

Electric brakes and manual, automatic or surge-type trailer brakes are

safe if installed properly and adjusted to the manufacturer’s

specifications. The trailer brakes must meet local and Federal

regulations.
