2011 HONDA ODYSSEY ECU

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.Always use saf ety chains when you
tow a trailer. Make sure the chains
are secured to the trailer and hitch,
and that they cross under the tongue
and 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.
An additional ATF (automatic
transmission f luid) cooler should be
installed. This device will help
prevent automatic transmission
overheating, which could cause
serious damage. The additional ATF
cooler can be obtained f rom your
dealer.
Your vehicle is designed to tow
without the need f or a load
distributing hitch. If you wish to use
one, please consult your trailer
maker f or proper installation and set-
up. Improper set-up could degrade
the handling, stability, and braking
perf ormance of your vehicle. A sway control device helps
minimize swaying that can occur in
crosswinds and in normal and
emergency driving maneuvers. If
you experience swaying when
pulling your trailer, consult the
trailer maker f or the specif ic type of
device and how to install it properly.
