Mercury 1999 Villager - Manual (Page 168)

Preparing to tow
Use the proper equipment for towing a trailer, and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
For towing trailers up to 907 kg (2 000 lb), use a weight carrying hitch
and ball which uniformly distributes the trailer tongue load through the
underbody structure. For towing trailers up to 1 588 kg (3 500 lb) use a
frame-mounted weight distributing hitch which transfers a portion of the
trailer tongue load to the front axle system.
Do not install a single or multi-clamp type bumper hitch, or a hitch
which attaches to the axle. Follow the towing instructions of a reputable
rental agency.
Whenever a trailer hitch and hardware are removed, make sure all
mounting holes in the underbody are properly sealed to prevent noxious
gases or water from entering.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle. 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 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.
