Hitches
Do not use a hitch that either clamps ontothe bumper or attaches to the axle.
Distribute the trailer load so 10-15% of thetotal trailer weight is on the tongue.
Weight-Distributing Hitches
WARNING
Do not adjust a weight-distributinghitch to any position where the rearbumper of the vehicle is higher thanit was before attaching the trailer. Doingso will defeat the function of theweight-distributing hitch, which may causeunpredictable handling, and could resultin serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, always use thefollowing procedure:
1.Park the loaded vehicle, without thetrailer, on a level surface.
2.Measure the height to the top of yourvehicle’s front wheel opening on thefender. This is H1.
3.Securely attach the loaded trailer toyour vehicle without theweight-distributing bars connected.
4.Measure the height to the top of yourvehicle’s front wheel opening on thefender a second time. This is H2.
5.Install and adjust the tension in theweight-distributing bars so that theheight of your vehicle’s front wheelopening on the fender is approximatelyhalfway between H1 and H2.
6.Check that the trailer is level or slightlynose down toward your vehicle. If not,adjust the ball height accordingly andrepeat Steps 1-6.
7.Lock the bar tension adjuster in place.
8.Check that the trailer tongue securelyattaches and locks onto the hitch.
9.Install safety chains, lighting and trailerbrake controls as required by law or thetrailer manufacturer.
