Hitches

Do not use hitches that clamp onto the vehicle’s bumper or attach to the

axle. You must distribute the load in your trailer so that 10%–15% of the

total weight of the trailer is on the tongue.

Load equalizing hitch

When hooking up a trailer using a load equalizing hitch, always use the

following procedure:

1. Park the unloaded vehicle on a level surface. With the ignition on and

all doors closed, allow the vehicle to stand for several minutes so that it

can level.

2. Measure the height of a reference point on the front and rear bumpers

at the center of the vehicle.

Attach the trailer to the vehicle and adjust the hitch equalizers so that

the front bumper height is within

⁄

” (13 mm) of the reference point. After

proper adjustment, the rear bumper should be no higher than in Step 2.

Note: Adjusting an equalizing hitch so the rear bumper of the vehicle is

higher than it was unloaded will defeat the function of the load

equalizing hitch and may cause unpredictable handling.

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.

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.

The braking system of the tow vehicle is rated for operation at the

GVWR not GCWR.
