Towing can require a variety of
equipment, depending on the size of
your trailer, how it will be used, and
how much load you are towing.
Discuss your needs with your trailer
sales or rental agency, and f ollow the
guidelines in the rest of this section.
Also make sure that all equipment is
properly installed and that it meets
f ederal, state, province, and local
regulations.
Any hitch used on your vehicle must
be properly bolted to the underbody,
using the six threaded holes
provided. A hitch and the required
f luid coolers designed especially f or
your Odyssey can be obtained f rom
your Honda dealer.If the total trailer weight is more
than 1,850 lbs (840 kg), you must
also use a weight distributing hitch.
This device transf ers weight f rom
the vehicle’s rear wheels to the f ront
wheels, and to the trailer’s wheels.
Caref ully f ollow the hitch maker’s
instructions f or proper installation
and adjustment.
If the total trailer weight exceeds
2,000 lbs (900 kg), you should install
a sway control device to minimize
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. Your trailer
maker can tell you what kind of sway
control you need and how to install it.
You must also have a transmission
f luid cooler and a power steering
f luid cooler installed. These coolers
are available only f rom your Honda
dealer.
Always use saf ety chains. Make sure
they are secured to both the trailer
and hitch, and that they cross under
the tongue so they can catch the
trailer if it becomes unhitched.
Leave enough slack to allow the
trailer to turn corners easily, but do
not let the chains drag on the ground.
